## Background
CROSS REFERENCE TO RELATED APPLICATIONS
The present invention is a continuation in part of application with Ser. No. 12/563,522 filed on Sep. 21, 2009 now U.S. Pat. No. 8,167,079.


BACKGROUND
1. Technical Field
The embodiments herein generally relate to motor vehicles and particularly to power transmission in motor vehicles. The embodiments herein more particularly relates to an automatic clutch system for power transmission in motor vehicles.
2. Description of the Related Art
For driving motor vehicles, the output power of the combustion engine must be transmitted to the driving wheels. The power of the engine is transmitted through a clutch to the gearbox. Usually, the clutch is engaged which can be disengaged by depressing a pedal, actuating a hand lever, or by any electromagnetic operating elements. The clutch disengaged to interrupt the power transmission from the engine to the gearbox and to permit an easy shifting of the gears.
Despite the advent and popularity of automatic transmissions, several automobiles and trucks are presently constructed with manually operated gear shifts. The vehicles with manual transmissions generally have several advantages, including increased fuel efficiency and better control of the vehicle. However, such vehicles must be equipped with independently operated clutches to disengage the engine from the drive shaft while the gears are being shifted. Since this action requires the application of a substantial force, a purely mechanical clutch must be actuated by the driver through a foot pedal mechanism.
Vehicles with manually operated throttles, brakes, and headlight dimmer switches are well known in the art. Conventional technologies also teach manual clutch control systems that are hydraulically or pneumatically powered with compressed air, brake-type fluid, or similar working fluids, or connected to the engine manifold vacuum system. These clutches are controlled generally by a manual operation of a hydraulic valve or a fluid switch, whereby a source of hydraulic power may be connected to a hydraulic cylinder and a piston arrangement or other equivalent energy-conversion mechanism which drives the clutch plates. These valves have an on-off character which precludes a gradual engagement or disengagement of the clutch and the rate of operation of the clutch is not subjected to the driver's control but is determined by the parameters of the hydraulic circuit in these systems. Hence a gradual engagement of the clutch during the starting of the vehicle from a standstill or the slipping of the clutch while driving under special conditions is not feasible with such a manual control valve. Also a constant gear shifting is required while driving in high traffic streets, which is a difficult task especially for the people who drive for a long time and suffering from a foot pain or a back ache.
There exists a need for an automatic clutch system to modify the regular stick shift automobiles to an automatic system for power transmission in motor vehicles.
The abovementioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
OBJECTS OF THE EMBODIMENTS
The primary object of the embodiments herein is to provide an automatic clutch system to modify a regular manual transmission in the automobiles to an automatic system for power transmission in the motor vehicles.
Another object of the embodiments herein is to provide an automatic clutch system which eliminates the need for a clutch pedal when a driver brakes and tries to stop the vehicle.
Yet another object of the embodiments herein is to provide an automatic clutch system which eliminates the need for applying a clutch at the time of starting the vehicle.
Yet another object of the embodiments herein is to provide an automatic clutch system which eliminates the need of a clutch for changing gears.
Yet another object of the embodiments herein is to provide an automatic clutch system which can be easily installed on all vehicles having clutch system.
Yet another object of the embodiments herein is to provide an automatic clutch system which is capable of being regulated for a variety of clutch pedals.
These and other objects and advantages of the present invention will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

FIG. 22 illustrates a block diagram of an electronic section of the automatic clutch system, according to an embodiment herein. The electronic section 230 of the automatic clutch system comprises an input section 231, an order/command circuit 232, an exit/output section 233, a feedback circuit 234, a plurality of monitors and a circuit connected to car's speed sensors. The input section 231 includes a keyboard for regulating the system by the user or driver of the vehicle and order/command transmission resources for placing the clutch lever in a due place. The keyboard of the electronic section 230 enables the user or driver of the vehicle to exercise the required regulations including the oscillation speed of the elevator mechanism, setting favorite points for placing the elevator mechanism and regulating the reaction times of the elevator mechanism. The order/command transmission resources in the input section 231 of the electronic section 230 of the automatic clutch system include three order/command transmission resources. The processor then sends a reaction order/command to the output section 233 depending on reception of at least any one of three order/command transmission resources.
A first order/command transmission resource to the clutch pedal lever is the gas pedal, which rotates around an axle and is connected to a secondary system. At the side of the gas lever there is the rotary encoder that generates 360 pulses in each rotation. The rate of change of angle of the elevator mechanism is reported to the processor through pulses generated by the rotary encoder and processor sends the required order/command to the output section 233. The second and third resources are two switches (first switch and second switch) that with the activation of each switch, the clutch pedal lever enter a default state for each switch.
The first switch is used for changing the gear while driving, resulting in putting the elevator mechanism in the endmost position. Upon pressing the first switch, the gas pedal is pressed to the end allowing a gear change action. Similarly, upon releasing the first switch, the elevator mechanism and the clutch pedal return to the previous state. Finally, the first switch is installed on a speed gear knob of vehicles. According to one embodiment herein, the first switch is temporarily installed on the command box in the electronic section of the automatic clutch system.
The second switch is adopted for elevating the clutch pedal lever. Upon pressing the second switch, the elevator mechanism and the clutch pedal lever enters the most possible primary state of lifting the clutch pedal lever upside. When the vehicle is completely stopped, the automatic clutch system leads the clutch pedal lever to the lowest position. For avoiding damage on car's (clutch) disk while the vehicle is stopped for a long time with the running engine, the second switch can avoid or prevent a placement of the clutch pedal lever in the endmost position. Finally, the second switch is installed on the steering wheel of the vehicle or on an end of vehicle's speed gear. According to one embodiment herein, the second switch is temporarily installed on the command box in the electronic section 230 of the automatic clutch system.
The order/command circuit 232 includes a command box to receive data from entries, send order/command to output section 233, investigating the output reaction in the feedback circuit 234 and representing all occurred reactions and regulations on the plurality of monitors. The order/command circuit 232 is composed of a microcontroller to which all output sections 233 and input sections 231, samplers (feedback circuits 234) and plurality of monitors are attached.
The output section 233 changes the linear position of the elevator mechanism according to the received data. These changes are made by a DC motor which converts an electrical energy into a mechanical energy and changes the position of the elevator mechanism by rotating. The DC motor used in this system is 12V and a momentary current required by the DC motor is 5 A while a permanent current needed is 3 A. For meeting the current used by the DC motor, an L6203 Driver is used.
The feedback circuit 234 or output sampler reports an output status from the output section 233 to the order/command circuit 232 in order to assess a true practice of orders/commands by processor and to ensure resistance of the automatic clutch system. For the stability of the automatic clutch system, the output status in the input section 231 needs to be reported all the time in order to determine and eliminate the errors through an error controller by comparing the output status with the desired rate. The rotary encoder is used in the feedback circuit 234 that can generate 100 pulses in every rotation. The axle of the rotary encoder is in a direct relation with the DC motors axle and with every rotation of the DC motor axle, axle of the rotary encoder also rotates once. By processing the pulses generated by the microcontroller, the exact details concerning the position of elevator mechanism is calculated to ensure the stability of the system.
The status of inputs, outputs, feedbacks and general alignments are represented on the plurality of monitors to enable user or driver of the vehicle for desired functioning. The pluralities of monitors are divided into 7-section monitors and LCD graphic monitors. All digits related to regulations and registers changed with the reaction of elevator mechanism are represented on 7-section monitors. Similarly, a LCD graphic monitor represents the location of elevator mechanism in numerical percentage besides displaying/representing a moving direction of the elevator mechanism.
The automatic clutch system is designed so that it needs speed sensors for clutching action. The automatic clutch system performs the clutching operation in two states. In the first state, the vehicle is in gear 1 and the car starts to move (speed from zero until when user want to change gear to 2) and in second state the user change gear from 1 to 2 and vehicle's speed raises (speed from that of when the user change the gear to 2 and thence speeds). For this purpose, a circuit is attached to the plurality of speed sensors and transfers speed to the main circuit of the automatic clutch system.
According to one embodiment herein, the plurality of sensors of vehicles have three legs including main base, two land and exit legs that generate pulse through circular rotation over its exit leg. The sensor shaft is connected to exit shaft of gearbox such that the pulses are generated over the exit leg of sensor along with the rotation of shaft. These kinds of sensors generate 8 pulses in every circular rotation over exit leg. To determine the vehicle's speed from the exit leg of sensor, a pulse counter is provided. The microcontroller installed on this circuit counts pulses per second and it will distinguish a speed of the vehicle based on the number/quantity of pulses.
Experimentally, one can say that every 7 pulses generated by the exit leg of the sensor will represent 1 km speed/hr. The exit leg of the sensor holds two wires, one of which is connected to ICU and the other to a km screen inside the vehicle. The exit leg is connected to a circuit both from the km screen and ICU to the circuit. The circuit attached to the speed sensor is attached to an LCD which will finally be set over by the command box of the automatic clutch system. The actual speed of the vehicle is represented in the LCD in the first line and the mean speed is represented in the second line.
According to one embodiment herein, when the vehicle reaches the considered speed or surpasses it, a relay installed in the circuit is activated and triggers its exit point functions.
According to one embodiment herein, whenever a speed is less than the predetermined speed, the relay comes to the off state (in this time, clutch pedal is pulled down by the system) and, vice versa. When a speed exceeds the predetermined speed, the relay comes to the on state (in this situation, clutch pedal is pulled up by the system).
According to one embodiment herein, two micro-switches are installed over the command circuit connected to the speed sensors for regulating the considered speed. The considered speed refers to the speed in which the user or driver changes the gear from 1 to 2. Finally, the circuit connected to the speed sensor is connected to the main circuit of the automatic clutch system for transmitting the orders related to the vehicle's speed to main circuit.
According to the embodiments herein, the installation and launching of the automatic clutch system includes the following steps: Firstly, the flooring of the elevator mechanism of the system is put across the clutch pedal lever. Then the placement, space and angle of the automatic clutch system are regulated with respect to the considered clutch pedal. The due placement of the system against the clutch pedal and the best possible state are determined and then the automatic clutch system is tightened by attaching the automatic clutch system to the vehicle's flooring. For doing so, the best place is chosen first for boring vehicle's floor and then the automatic clutch system is attached to the vehicle's flooring. The automatic clutch system of the present invention is installed in different places in the vehicle's flooring, i.e. user or driver may have enough space to generate holes to fix the automatic clutch system on the flooring of the vehicle.
After installing the automatic clutch system to the flooring of the vehicle, the placing of gas lever is regulated in such a manner that the support base of the gas lever is placed between gas pedal and brake pedals. This action is done in a way that at the time of pressing the gas pedal and a brake pedal, the foot of the user or driver should not touch the automatic clutch system. This section of system is designed such that the gas lever can be placed in the best place.
Finally, the angle and the distance of the gas lever handhold from the gas pedal are adjusted. The head of the gas lever's handhold is put underneath the gas pedal so as to move down the gas lever's handhold with a minimum pressure applied on the gas pedal.
After the final installation of the automatic clutch system to car pedals, an electrical circuit of the system is regulated. To do so, sockets of DC motor, gas encoder, clutch encoder, electricity cable, and cable connected to the speed sensor are attached to the backside of the steering wheel of the vehicle.
After the complete installation, the automatic clutch system is activated and the required regulations on clutch pedal are performed. Since clutch pedals vary from one vehicle to another, different clutching parameters are considered for the automatic clutch system thereby enabling to regulate the automatic clutch system according to the clutch pedal.
In some vehicles, the clutch functions at a lower distance from the vehicle's floor while in some others the distance between the clutch pedal and the flooring is higher. Furthermore, the hardness of clutch pedals is different in different types of vehicles. Even a movement style of the clutch pedal from up to down is different for different types of vehicles. The automatic clutch system disclosed in the embodiments herein can be adjusted for all possible situations.
Over the steering wheel of the automatic clutch system, 13 segments are installed. Each of these segments is related to a special part of regulations so that, the automatic clutch system will become ready to function after the regulation of different parameters and storage of available data.
FIG. 23 illustrates a block circuit diagram for a command box of an electronic section of the automatic clutch system, according to an embodiment herein. The command box receives data from entries, send order/command to output section, investigate the output reaction in the feedback circuit and represent all occurred reactions and regulations on the plurality of monitors. The order/command circuit is composed of a microcontroller to which all output section and input sections, samplers (feedback circuits) and plurality of monitors are attached.
There are 13 digital LCDs on the command box 280 of the system. Each of the LCDs is used for regulating a determinate part of the automatic clutch system. These 13 LCDs are placed in three rows on command box as shown in FIG. 23.
Six single-digits LCDs 281 divided to 3 sets. Each set is used to display oscillation speed of elevator mechanism in different states. These 3 sets of LCD are arranged in middle row as shown in FIG. 23.
Three 3-digits LCDs 282 are placed in the lower row for displaying the position of the elevator mechanism and for determining primary and secondary position of the elevator mechanism. The LCD arranged at the center/middle in the lower row displays/represents a place/location of elevator mechanism in each point of encoder installed on it and the LCDs provided at the two sides in the lower row display/represent primary and secondary places of elevator mechanism which are adjustable. The primary and secondary places represent/indicate the clutching action of the automatic clutch system. The primary and secondary places of the elevator mechanism are primarily registered in the command circuit.
Also, there are two 3-digits placed at the ends and one 2-digit LCDs 283 is placed in the middle between the two 3-digit LCD in the 1st row. The 3-digit LCD represents/displays a movement rate of gas lever and its angle change while the 2-digit LCD represents/displays a coefficient of gas lever. The other 3-digit LCD represents/displays the running hours of the system. When the gas lever moves downward, in proportion to the considered clutch pedal, the clutch pedal also moves upward such that the digit generated by gas lever (rate of output pulse of encoder) is multiplied to a special number and is sent to elevator mechanism and elevator mechanism issues the required order/command for the movement of the clutch pedal. This command is sent to a command system, for instance, to have a determinate upward move when gas pedal has a 1 cm downward move.
A single-digit LCD 284 is placed in the corner of the command box. The size of the single-digit LCD 284 is more than that of the other LCDs. The command circuit designed for this system is adapted to save different clutching states in different vehicles for further applications. This single-digit LCD 284 represents/displays an executive data in numerals/digits.
Further the two LCDs 285, 286 are placed on the command box so that one LCD 285 has dimensions of 25×72 mm while the other LCD 286 has a size of 130×72 mm. The bigger LCD 286 represents/displays an upward or downward moving direction of the clutch pedal. It also represents/displays upward or downward movement rate of the clutch pedal in numerical percentage style. The small LCD 285 is connected to a speed sensor to represent/display the vehicle's speed and the speed required for a gear change from 1 to 2. On the LCD, the required speed is regulated by 2 micro-switches set beside it.
A key pad 287 is provided on the command box 280 for regulating and changing the data as shown in FIG. 23. Its functioning is such that with the pressing and holding operation of a set key for 3 seconds, the automatic clutch system leaves the circuit and enters a regulations state. In this situation, the first LCD 281 starts flashing. Upon entering the considered data and pressing the enter key, the next LCD 282 starts flashing and by doing so, the user or driver may enter the required data for the considered clutch pedal to the system. In the final step of setting operation, the single LCD 284 placed in the corner of the command box 280 starts flashing and in this stage, the user or driver may enter the data by saving the digit into it. For instance, if the series of data for digit 1 is saved, then user or driver should save the next series of data on digit 2 or another digit because the new data will replace the old data omitting the latter when the data is saved on the same digit. When the user or driver wants to play the previously saved data series, the user or driver should press and hold the enter key for 3 seconds until when the single-digit LCD 281 starts flashing. In this situation, only the single digit LCD 281 at the corner of the command circuit will flash. Then, by entering the considered digit saved previously and pressing the enter key, the user may play the desired series of data.
When the command box of the automatic clutch system is in the setting phase or is rendering previously-saved data, the automatic clutch system leaves the circuit and stops functioning. For this purpose and for starting the automatic clutch system, the user should exit the settings menu.
According to the embodiments herein, when automatic clutch system is installed in its place and the vehicle is fully stopped, the clutch pedal is completely lead down by the automatic clutch system. In this situation, the pressing of gas pedal makes the encoder installed on gas pedal's lever to generate a pulse. The higher is the pressure applied on gas pedal the more will be the quantity of the pulses generated such that the encoder generates 1 pulse with each degree of downward movement of the lever.
The pulse generated by gas lever is processed in the command circuit and is multiplied to a number determined in advance by the operator on the command box. The achieved number is sent to the elevator mechanism and in proportion to the increased pressure applied on gas pedal, the clutch pedal moves upward. By releasing the gas pedal, the clutch pedal returns to its previous state and settles in the endmost point assigned for it.
This situation lasts until when the user drives in gear one and in a determinate speed. For instance, when the speed of the vehicle reaches the point on which the user need to change a gear from 1 to 2 (required speed), the elevator mechanism automatically leads the clutch pedal towards up. This eliminates the need for pushing the clutch pedal when the speed of the vehicle increases and the user need to change to the gear 2 unless when the user want to change the gear or brake.
In this stage, the user needs to push the clutch pedal for changing the gear for a placement of the clutch pedal in the top. To facilitate this, a special key is devised and installed above the speed gear. Upon pressing the special key, the user may change the gear. Then the clutch pedal returns to its previous place, when the user releases the special key.
In the situation, when the user wants to stop the vehicle, the automatic clutch system will function as follows. If the vehicle's speed is less than the required speed, by releasing the gas pedal, the clutch pedal is lead downward and the user can brake and stop the vehicle. But if the speed of the vehicle is more than the required speed, by pressing the brake pedal, the automatic clutch system will keep up the clutch pedal until the speed is reduced to a speed less than the required speed for an optimized stopping operation. In this time the clutch pedal is lead downward automatically and the vehicle is ready to be stopped softly.
When your vehicle is stopped, the clutch pedal is lead downward. In this situation, when the vehicle is stopped for a long duration and the clutch pedal is kept at lower points, this may reduce the life of disk and the life of the clutch disk. To avoid this, a special key is designed and by pressing the key, the user may lead the clutch pedal downwards in case the vehicle takes a longer time to stop. The special key is installed on the steering wheel or over the speed gear of the vehicle or temporarily installed on the front section of the command box.
The automatic clutch system of the embodiments herein is an electromechanical system, which fully eliminates the need for a clutch pedal in vehicles and provides the user to drive in all driving situations without the need for a clutch pedal. The automatic clutch system can be installed in minimal time as less than 10 min and whenever the automatic clutch system is not required, the user can retire it and use the conventional clutch pedal of the vehicle. The automatic clutch system can be installed on all vehicles having different clutch pedals and its price is economical. In addition, the user may disassemble the auto clutch system from the user vehicle and install it on another vehicle.
The automatic clutch system controls the clutching of the vehicle based on a pressure applied on the gas pedal by the user and in proportion to the speed of the vehicle. With a single regulation of system's electrical circuit, one can convert a manual transmission in a vehicle to a full auto-clutch vehicle (semi-automatic transmission) and eliminate the clutch pedal from the vehicle to drive in all speeds without the need for pressing a clutch pedal.
