摘要： A system and method for generating a pressure-volume curve for a hydraulic system in a vehicle. The system includes a plunger coupled to the hydraulic system, a pressure sensor configured to detect a pressure of the hydraulic system, and an electronic controller configured to access a prior pressure-volume curve from a memory, generate a signal to move the plunger, receive a pressure from the pressure sensor, generate a new pressure-volume curve based upon the received pressure and a position of the plunger, compare the new pressure-volume curve to the prior pressure-volume curve, in response to the new pressure-volume curve and the prior pressure-volume curve differing by at least a threshold value, replace the prior pressure-volume curve with the new pressure-volume curve in the memory, and actuating the hydraulic system based upon the stored pressure-volume curve.

摘要： A method and system is provided for determining a direction of movement of an electric vehicle. The method and system includes determining the direction of rotation and the direction of torque of a motor shaft, determining an operating gear of the vehicle, and determining a previous direction of movement of the vehicle. The method and system then determines if the vehicle is moving forward or backwards. The method and system also determines whether the vehicle is motoring (i.e., converting electric power to mechanical power) or generating (i.e., converting mechanical power into electric power).

摘要： A system and method for performing a diagnostic on a hydraulic system in a vehicle while the vehicle is at a standstill. The method includes, by means of an electronic processor, moving a plunger at a constant rate, determining a position of the plunger, receiving a pressure of the hydraulic system from a pressure sensor, comparing the determined position and the measured pressure to a position versus pressure graph, and sending a diagnostic to a diagnostic indicator.

摘要： A hill rollback control system and method for controlling a rollback speed of a motor vehicle with wheel brakes. Upon ascertaining that the vehicle is rolling back, the system and method determine, based on a grade angle of the terrain that the vehicle is traveling on and a temperature of a transmission, a target rollback speed for the vehicle. The target rollback speed is lower when the grade of the terrain is above a threshold value. Also, the target rollback speed is lower when the temperature of the transmission is above a threshold value. The actual rollback speed of the vehicle is set and maintained at the target rollback speed by applying the vehicle's wheel brakes.

摘要： Systems and methods for a braking a vehicle. In one example, the braking system includes a friction braking system, a regenerative braking system, and an electronic processor. The electronic processor is communicatively coupled to the friction braking system and the regenerative braking system. The electronic processor is configured to receive a driver brake request and determine a brake failure state. The brake failure state indicates a brake failure. In response to determining the brake failure state, the electronic processor applies a braking force based on the driver brake request. The braking force includes a frictional braking force generated by the friction braking system and a regenerative braking force generated by the regenerative braking system.
