DETAILED DESCRIPTION
The present disclosure will now be described with reference to the accompanying drawings in which a preferred embodiment is shown. The disclosure, however, may be embodied in many different forms and therefore should not be construed as limited to the embodiment as set forth herein.
The present disclosure is directed to a device to teach a driver of a vehicle improved fuel efficient driving techniques while driving the vehicle. The device uses feedback from the vehicles on-board diagnostic system (OB-11 port), an angle of inclination of the vehicle based on sensors inside the device itself, and an adaptive governor provided on the vehicle. The adaptive governor system takes information from a geo-mapping service, such as a GPS system, in order to set a maximum speed the vehicle can achieve based on the road traveled. The device will also calculate a score for the driver based on how well the driver complies with instructions from the device. A high score indicates good driving habits and fuel efficient driving. The driving score can be uploaded to a web server for evaluation by the driver, management personnel, a driving instructor or parent.
FIG. 1 shows the device 10 itself before attachment to the dashboard of a vehicle. The device shown in FIG. 1 is for illustrative purposes only and should not limit the physical design itself. For example, the device may be circular or square rather than rectangular as illustrated. The device includes a display screen 1 and an audio system 2 which provides voice commands. The exact layout of the screen and audio system should not be limited to the illustration. The device also includes a place to attach connectors 3. The exact location of the connectors shown in the figure is also not limiting. The connectors 3 attach to the on-board diagnostic system of the vehicle, to the adaptive governor system and to the geo-mapping service.
The device 10 has an input unit for the driver to enter information, such as weight of the vehicle. The input unit can be, for instance, a touch screen on the display screen 1. Other input devices and methods can also be used. Inside the device, as shown in FIG. 3, is at least a display controller 11 to control the display screen 1 and a controller or control unit 12 which obtains data from the on-board diagnostic system 100. The control unit 12 also obtains information from a geo-mapping service 300 The geo-mapping service can be a wireless service. The device 10 will receive signals from any GPS satellite and will retrieve data from a database to determine the speed limits at the location on the road where the vehicle is traveling.
In addition, the device 10 contains sensors 13 to measure the angle of inclination of the vehicle. The sensors 13 could be similar to a pendulum. As the vehicle moves up and down due to hills, the pendulum will move. The device will measure how far the pendulum has moved and calculate an angle of inclination of the vehicle. Although a pendulum is described here, the sensors 13 are not limited thereto and can be any sensor which measures an angle of inclination including accelerometers, gyroscopes, and the like. The output from the sensors 13 is input to the control unit 12. The device 10 may also contain light sensors 14. The output from the light sensors 14 are input to the control unit 12 so that the amount of sunlight entering the vehicle can be determined.
FIG. 2 illustrates the device 10 mounted on a dashboard 20 of the vehicle adjacent to the steering wheel 30 and below the windshield 40 so the driver can see the display screen 1 of the device 10. Placement of device 10 in FIG. 2 is for illustration only and can be elsewhere in the vehicle. Connectors 3 connect the device 10 to the on-board diagnostic system 100, the adaptive speed governor 200 and to the geo-mapping service 300.
As the operator of the vehicle drives the vehicle, the control unit 12 of the device 10 will receive output signals from the on-board diagnostic system 100 for engine RPM, acceleration, idle time and time in cruise control. Additional output from the on-board diagnostic system 100 to the control unit 12 of the device 10 will be information about the maintenance of the vehicle. The information received by the control unit 12 will be used to determine if the maintenance is affecting the efficiency of the vehicle. In addition, the control unit 12 can determine if the vehicle needs to be serviced.
At the start of a trip, the display screen 1 will display information to the driver. In particular, the driver will be prompted to enter the weight of the load the vehicle is carrying or pulling. The driver can enter the information via the touch screen or via another type of input unit. In addition, the control unit 12 will obtain output from the level sensor or inclination sensor 13, located within the device 10 itself, indicating the inclination of the vehicle. Based on the RPM, acceleration, idle time, cruise control information, maintenance information, weight of load and angle of inclination, the control unit 12 will output information to the display controller 11 for the display screen 1 to display visual instructions on how to increase fuel efficiency through better driving habits. In addition, audio instructions will also be provided to the driver via audio controller 15 to the audio system 2. The instructions include when to slow down, accelerate, maintain speed, accelerate more slowly, accelerate more quickly, etc. Thus, the device 10 will provide real-time coaching to the driver while the driver is operating the vehicle. It should be noted that the driving tips provided to the driver are based upon outputs from the on-board diagnostic system 100 as well as the inclination sensor 13 which indicates the level of inclination of the vehicle as the vehicle is driving along. The device 10 also receives signals from the geo-mapping service 300 via the GPS input 16 about the speed limit of each road the vehicle is traveling on. The output from the geo-mapping service 300 to the device 10 will cause the control unit 12 to issue visual and audio alerts via the display screen 1 and audio system 2 to the driver such as when to slow down or accelerate ahead of time based on the route taken and the speed limit of the road.
Additionally, the vehicle may have an adaptive speed governor system 200. The adaptive speed governor system 200 are known in the art. The speed governor system 200 is a micro-controller based electronic unit which constantly monitors the speed of the vehicle and controls the vehicle speed within preset limits. Thus, the speed governor can restrict the maximum speed of a vehicle to a preset limit.
The device 10 of the present disclosure has the ability to control the computer system of the vehicle that regulates the governing speed of the vehicle by adjusting the maximum speed of the vehicle based on the speed limit of the road. The maximum speed of a vehicle is regulated by an on-board computer system. Rather than using a preset speed for the vehicle, the device 10 of the present disclosure would input the speed limit to the on-board computer system that the geo-mapping system provides for each road in order to set the maximum vehicle speed. Based on the maximum speed of the road from the geo-mapping service 300, the control unit 12 will output the maximum vehicle speed for the adaptive speed governing unit 200 in order to control the maximum speed the vehicle can go. This will aid the driver by preventing the vehicle from exceeding the speed limit for the road.
An additional feature of the device is that the device will receive information about the maintenance of the vehicle from the on-board diagnostic port 100. The control unit 12 of the device can then determine if maintenance of the vehicle is affecting the efficiency of the vehicle and whether the vehicle needs to be serviced. This is done by analyzing every possible alert the on-board diagnostic system outputs for maintenance issues and determining whether the alert effects fuel efficiency. For example, maintenance issues for vehicle lights do not affect fuel efficiency and can be ignored by the system according to an embodiment of the disclosure whereas tire pressure, and engine issues will affect fuel efficiency. In particular, the control unit 12 will classify if any maintenance issues are affecting fuel efficiency. In addition, the control unit 12 will determine how far the vehicle can still travel safely and/or efficiently before being serviced. This is based on the approximate number of miles the vehicle can still travel when the alert is issued before fuel efficiency is diminished at all, or before fuel efficiency is diminished below a certain threshold. This information can then be displayed to the driver or downloaded wired or wireless to a web server 400 or a smart phone 500.
Once the driver has finished traveling in the vehicle, the device will use a system of formulas to calculate a score indicating how well the driver complied with the device's visual and audio instructions. The formula represents a pattern when the driver speeds up or slows down going up and down hills for an optimal vehicle route and mode of operation. The formula will change based on the weight the vehicle is carrying. The device will calculate the deviation between the vehicle's actual route and mode of operation and the optimal vehicle route and mode of operation. The calculated score indicates how close to the optimal the vehicle was driven. Thus, the score will represent how fuel efficiently the driver was driving. The score will be sent to the web server 400 where the owner of the vehicle or manager of the vehicle can monitor and evaluate the driver's performance. The manager/owner will also be able to compare data prior to installation of the device 10 on the vehicle with data after installation of the device 10 on the vehicle in order to determine estimated cost savings from improved driving habits. This is especially important when the device 10 is installed on a commercial vehicle such as a truck.
A further feature of the device 10 is that light sensors 14 may be provided on the device 10 or the device 10 may be attached to light sensors found within the interior of the vehicle. The output from the light sensors are used by the control unit 12 to determine how much sunlight enters the vehicle. The driver's score will improve when the driver allows sunlight to enter the vehicle while the vehicle is idle in the winter months since the increase in heat from the sunlight in the interior of the vehicle will allow the interior of the vehicle to warm up without turning the heater on. Similarly, the driver's score will improve in summer months when the idle vehicle is kept shaded in order to keep the interior of the vehicle cool without turning the air condition on to cool the vehicle.
The present disclosure can be used in private vehicles as well as commercial vehicles. The present disclosure is directed to a device to coach a driver of the vehicle to have good driving habits. The present disclosure includes the level of inclination of the vehicle into consideration when creating driving tips for the driver.
While the disclosure has been described above, it will be appreciated that modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the disclosure. Thus, the scope of the disclosure should be defined by the appended claims.
