DETAILED DESCRIPTION OF THE INVENTION
Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.
In various exemplary embodiments, the technology described herein provides devices, a system, and methods for parking brake remote actuation, thereby to insure that the parking brake of a vehicle equipped with airbrakes is set when the driver exits the cab and to provide increased safety in the prevention of rollaway vehicle accidents.
Referring now to FIGS. 1 and 2, in one exemplary embodiment, the technology described herein provides a system 10 for the remote actuation of a parking brake in a vehicle, thereby to insure that the parking brake of the vehicle is set when the driver exits the vehicle to air in the prevention of a rollaway vehicle accident.
The system 10 includes an actuator 14 disposed within a vehicle equipped with air brakes and a parking brake button 16. In such vehicles, the parking brake button 16 typically is pulled outwardly or lifted by the driver to set the parking brake, and the parking brake button 16 typically is pushed inwardly or depressed by the driver to disengage the parking brake.
The actuator 14 is coupled to the parking brake button 16 such that it is configured to set the parking brake of the vehicle upon the occurrence of a predetermined event. The predetermined event, is for example, when a driver exits the vehicle neglecting to first set the parking brake. In at least one embodiment, the actuator 14 is an electro-mechanical device that can mechanically move the parking brake button 16 and that is equipped with a means for electronic communication with other devices that can indicate to the actuator 12 that it is to set the parking brake.
The system 10 includes a remote actuation device 12. The remote actuation device 12 is configured to be with the driver of the vehicle. The remote actuation device 12 is configured to indicate to the actuator 12 when the driver exits the vehicle such that the actuator 12 sets the parking brake if not already set. In at least one embodiment, the actuator 12 is placed on a dashboard 32 such that it is easily coupled to the parking brake button 16.
In at least one embodiment, the system 10 also includes a lever 18. The lever 18 is coupled to the actuator 14 and configured to raise a pull handle of the parking brake button 16 and thereby set the parking brake once the actuator 14 is activated and moves the lever. In at least one embodiment, the lever is partially disposed within the actuator 14, and hingedly coupled within the actuator 14. Additionally, the lever 18 is placed adjacent to the parking brake button 16 such that on command it can raise and lower parking brake button 16 to thereby set or disengage the parking brake of the vehicle. As will be apparent upon reading of this disclosure, other means to coupled the actuator 14 to the parking brake button 16 are anticipated that do not require a lever, but are still capable of lifting and depressing the parking brake button 16.
In at least one embodiment, the system 10 further includes a POWER light 22 on the actuator 14. The POWER light 22 on the actuator 14 is configured to indicate to the driver that the power to the actuator 14 is on and the actuator is activated and ready for use.
In at least one embodiment, the system 10 also includes a READY light 24 on the actuator 14. The READY light 24 on the actuator 14 is configured to indicate to the driver that the actuator is ready and activated.
In at least one embodiment, the system 10 further includes a DEPLOY light 26 on the actuator 14. The DEPLOY light 26 on the actuator 14 is configured to indicate to the driver that the actuator is used.
In at least one embodiment, the system 10 also includes a SYSTEM OVERRIDE switch 20. The SYSTEM OVERRIDE switch 20 is disposed on the actuator 14. The SYSTEM OVERRIDE switch 20 is configured for operable engagement by the driver in a circumstance when the system for the remote actuation of a parking brake is deactivated temporarily. By way of example, a driver may wish to override the system utilizing the SYSTEM OVERRIDE switch 20 when towing another vehicle.
In at least one embodiment of the system 10, the actuator 14 is further configured to prevent disengagement of the parking brake unless the remote actuation device 12 is present. For example, should a driver enter a vehicle in which the parking brake is set, but while not having the remote actuation device 12 present, and thereby begin to disengage the parking brake, the actuator 14 disallows the disengagement of the parking brake since the safety system is defeated if the driver is without the remote actuation device 12. This adds additional safety to the system 10 and prevents use when a driver forgets the remote actuation device 12.
In at least one embodiment of the system 10, the remote actuation device 12 is an electronic card configured for electronic communication with the actuator 14. In this embodiment, the remote actuation device 12 is configured for electronic communication with the actuator 14. The presence of the remote actuation device 12 is thereby recognizable by the actuator 14.
In at least one embodiment of the system 10, the remote actuation device 12 is an RFID card configured for detection by the actuator 14. In this embodiment, the remote actuation device 12 is configured for electronic communication with the actuator 14. The presence of the remote actuation device 12 is thereby recognizable by the actuator 14. Both active and passive RFID cards can be utilized in the system 10 in various embodiments.
In at least one embodiment, the remote actuation device 12 is a smart phone or like portable electronic device running an application for communication with the actuator 14.
In at least one embodiment, the system 10 further includes a controller 28. The controller 28 is disposed within the actuator 14 and is configured for communication with the remote actuation device 12. In various embodiments, the controller 28 includes a processor, a memory, and a means for storing data. In at least one embodiment, the controller 28 includes an RFID reader. In at least one embodiment, the controller 28 is configured for communication with a key FOB.
In at least one embodiment, the system 10 also includes a sensor 30. The sensor 30 is disposed within the actuator 14 and is configured to detect the remote actuation device 14. In at least one embodiment the sensor 30 is an RFID sensor which can be detected by an RFID reader at the actuator 14. In various other embodiments, the sensor 30 is an electronic sensor configured to detect the presence of the remote actuation device 14.
Referring now to the FIGS. 3 and 4, flowchart diagrams 300 and 400 are shown, depicting a method to set the parking brake of a vehicle by remote actuation, thereby to insure that the parking brake of the vehicle is set when the driver exits the vehicle.
As will be apparent to one of ordinary skill in the art, upon reading this disclosure, some of the method steps depicted in FIGS. 3 and 4 may be implemented in varying order depending on the given circumstances. Additionally, one or more method steps depicted in the Figures may be omitted or substituted under the appropriate circumstances.
At step 302, a vehicle is equipped with an actuator 14. The step 302 includes equipping a vehicle with an actuator disposed within a vehicle equipped with air brakes and a parking brake button and coupled to the parking brake button and configured to set the parking brake upon the occurrence of a predetermined event. By way of example, but not of limitation, a vehicle dashboard 32 is equipped such that the actuator 14 is mounted adjacent to the parking brake button 16 so that it can lift and depress the parking brake button 16 as needed during operation of the system 10.
At step 304, a vehicle driver is equipped with a remote actuation device 12. This step 304 includes utilizing a remote actuation device 12 configured to be with the driver of the vehicle, or on the driver in some form, and to indicate to the actuator when the driver exits the vehicle such that the actuator sets the parking brake if not already set.
At step 306, the remote actuation device is paired to the actuator device. This step 306 includes pairing the actuator 14 device to the remote actuation device 12 for communication between the devices. By way of example, and not of limitation, the pairing may be through a wireless technology protocol, such as Bluetooth®, or through RFID technology, whether active or passive. Other means of electronic, wireless communication between the actuator 14 and the remote actuation device 12 are utilized in various embodiments.
At step 308, the departure of the remote actuation device 12 with the driver is identified by the actuator 14. This step 308 includes identifying a departure by the driver, by the remote actuation device 12 with the driver, and as detected by the actuator 14.
At step 310, a status is communicated to the actuator 14. This step 310 includes communicating a status to the actuator 14 in the vehicle from the remote actuation device 12 with the driver. This step enables the actuator to know that the remote actuation device 12 is no longer in the vehicle and that, if not already set, that the parking brake should be set automatically by the actuator 14.
At step 312, the parking brake is engaged. This step 312 includes engaging the parking brake, via the parking brake button 16, by the actuator 14. The step 312 of setting the parking brake occurs automatically when the remote actuation device 12 has been detected as away from the vehicle by a predetermined existence or other event trigger criteria.
At step 402, the system is overridden by the driver. This step 402 includes overriding the actuation by a SYSTEM OVERRIDE switch 20. In certain circumstances, such as towing another vehicle, for example, a driver may wish to override the system by utilizing the SYSTEM OVERRIDE switch 20.
At step 404, RFID is utilized for the remote actuation device 12. This step 404 includes utilizing an RFID or another type of electronic card for the remote actuation device 12 for electronic communication with the actuator 14. The RFID may be active or passive in various embodiments.
At step 406, a signal is sent from the remote actuation device 12 to the actuator 14. This step 406 includes sending a signal from the remote actuation device 12 to the actuator 14.
At step 408, a signal is sent from the actuator 14 to the remote actuation device 12. This step 408 includes sending a signal from the actuator 14 to the remote actuation device 12.
At step 410, disengagement of the parking brake is prevented. This step 410 includes preventing disengagement of the parking brake unless the remote activation device 12 is present.
Although this technology has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples can perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the technology disclosed herein and are intended to be covered by the following claims.
