Various examples of a controller, method and system for determining positions of a tractor-trailer vehicle train are disclosed. In one example a tractor controller is manually-initiated or a user-initiated tractor controller and includes an electrical control port for receiving an electrical start signal, and a communications port for receiving data. A processing unit of the tractor controller includes control logic and is in communication with the electrical control port. The control logic is capable of receiving, in response to the electrical start signal, a data signal at the communications port which includes a GPS signal and a unique identification which corresponds to the towed vehicle. At a predetermined response time, the tractor controller determines the position of the towed vehicle in the tractor-trailer vehicle train based on the data received from the towed vehicles.

Various examples of a controller, method and system for monitoring a tractor-trailer vehicle train are disclosed. In one example a tractor controller is manually-initiated or a user-initiated tractor controller and includes an electrical control port for receiving an electrical sync signal and an electrical start signal, and a communications port for receiving data. A processing unit of the tractor controller includes control logic and is in communication with the electrical control port. The control logic is capable of receiving a data signal at the communications port which includes a time value and a unique identification which corresponds to the towed vehicle in response to the electrical start signal. At a predetermined response time, the tractor controller determines the position of the towed vehicle in the tractor-trailer vehicle train based on the data received from the towed vehicles.

A backward movement indicator apparatus is provided for a vehicle having an alert device. The backward movement indicator apparatus comprises an image capture device arranged to capture image data which is representative of objects in vicinity of the vehicle. The backward movement apparatus further comprises an electronic controller arranged to process the captured image data to provide a signal which is indicative of the vehicle moving backwards.

A motor controller unit facilitates modifying pressure thresholds and motor operation mode for an air compressor in a hybrid commercial vehicle as a function of vehicle air demand and comprises a processor configured to execute computer-executable instructions comprising monitoring vehicle air system pressure, calculating air demand generated by the vehicle air system, and determining that the vehicle air system air demand is greater than a predetermined air demand threshold. A cut-out pressure threshold for the compressor motor is increased and the air compressor motor is switched from an on/off mode to a continuous run mode wherein pressure is maintained in the air system to be between a cut-in pressure threshold and the increased cut-out pressure threshold. The compressor motor operates in the continuous run mode until air demand falls below the predetermined air demand threshold.

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.

A method and apparatus for processing two high speed signals through a single high speed input terminal of a microprocessor uses a multiplexing circuit connected between the signal conditioners from the wheel speed sensor and the microprocessor. The multiplexing circuit converts the square wave signal as generated by the signal conditioning circuits into a series of interrupts. The multiplexing circuit includes three hardware semaphores or flip-flops which are set by the interrupts generated from wheel speed signals. The semaphores or flip-flops are reset by the microprocessor.
