摘要： A method of optimizing steering and stability performance of a vehicle includes measuring a set of inertial data during a regenerative braking event (RBE), calculating a set of vehicle performance data using the inertial data, and comparing the performance data to calibrated threshold data to determine a maximum regenerative braking torque (RBT). The maximum RBT is automatically applied during the active RBE. The vehicle includes a chassis, an electric motor/generator for applying an RBT, a frictional braking system, chassis inertial sensors for measuring a set of chassis inertial data, and a controller having an algorithm for calculating a set of vehicle performance data using the chassis inertial data. The controller determines the maximum RBT by comparing the vehicle performance data to corresponding threshold data. The chassis inertial sensors can include accelerometers, a yaw rate sensor, a steering rate sensor, speed sensors, and/or a braking input sensor.

摘要： A vehicle brake system and method designed to maximize the contributions from a regenerative braking system, yet still provide adequate safety measures that address potential regenerative braking failure. According to one embodiment, the method determines both a requested deceleration from the driver and an actual deceleration experienced by the vehicle, and uses the difference between these two values to calculate a deceleration error that can be integrated over time and compared to an error threshold. If the integrated or accumulated deceleration error surpasses the error threshold, then the method may reduce or disable the regenerative braking system until it can confirm that it is operating properly.

摘要： A method for operating a vehicle brake system having both frictional and regenerative braking capabilities. According to one embodiment, the method monitors wheel slip at a number of vehicle wheels, evaluates individual wheel slip at a single wheel as well as collective wheel slip involving multiple wheels, compares the wheel slips to one or more speed-based thresholds that are based on vehicle speed, and uses the comparisons to help distinguish between those situations that warrant disengagement of regenerative braking operations and those that do not.

摘要： A method for operating a vehicle brake system during a wheel slip condition. According to an exemplary embodiment, the method involves receiving a requested brake torque, monitoring wheel slip, and if no wheel slip is detected then operating the vehicle brake system according to the requested brake torque.
