Abstract:
1. A method of optimizing performance of a vehicle having a plurality of road wheels, and a regenerative braking capability adapted for electronically braking the vehicle during an active regenerative braking event (RBE), the method comprising: measuring a set of inertial data of the vehicle during the active RBE using a plurality of inertial sensors, including measuring a rotational speed of each of the road wheels, an input steering angle of the vehicle, an acceleration value of the vehicle, and an actual yaw rate of the vehicle; transmitting the set of inertial data to a controller of the vehicle; calculating, via the controller, a set of vehicle performance data using said set of inertial data, including calculating each of a wheel slip rate of the road wheels, a velocity of the vehicle, a vehicle acceleration vector, and a desired yaw rate; comparing said set of vehicle performance data to a corresponding set of calibrated threshold data to thereby determine a variance with respect to the corresponding set of calibrated threshold data for each of the input steering angle, the wheel slip rate, the velocity, the vehicle acceleration vector, and the desired yaw rate; calculating a maximum regenerative braking torque (RBT), including: automatically applying said calculated maximum RBT via an electric motor/generator during the active RBE.
