Abstract:
Various embodiments of an apparatus and method for configuring a tire pressure monitoring system are disclosed. One method comprises rotating a first tire of a plurality of tires on a vehicle and receiving a signal indicative of the speed of rotation of the first tire from a wheel speed sensor associated with the first tire. A controller associates the first tire with a wheel location in response to receiving the signal from the wheel speed sensor. A tire pressure sensor in the first tire generates a tire characteristic signal in response to the rotation of the first tire. The controller receives the tire characteristic signal and associates the tire characteristic signal with the wheel location in response to receiving the tire characteristic signal within a predetermined time period from receiving the signal indicative of the speed of rotation of the first wheel.
Abstract:
A receiver capable of receiving a remote vehicle stop request signal is mounted to a commercial vehicle and connected to the vehicle antilock braking ECU by a vehicle communication bus. The receiver may also be capable of transmitting a signal, thereby allowing the desired vehicle to be isolated. Furthermore, a user input device may be mounted to the vehicle that allows manual input of a park signal. When the park signal has been received by the vehicle ECU, the vehicle braking system is employed, thereby preventing the movement of the vehicle.
Abstract:
A system and method for detecting alternator condition is provided. Information is taken from the vehicle powerline and the communication links, and processed by the vehicle ECU, such as the vehicle antilocking brake system ECU, to obtain data. The battery voltage ripple amplitude is then calculated and compared at different engine speeds. If the difference in the ripple amplitude at the different engine speeds is greater than a predetermined threshold value, a signal is sent indicating that the alternator has failed.
