Abstract: A method and system for controlling a vehicle to improve vehicle dynamics are provided. The method includes receiving data from a plurality of sensors which monitor vehicle dynamics by monitoring at least wheel and steering movements associated with a vehicle system used in controlling vehicle dynamics by control outputs from a holistic vehicle control system. Then, estimating states of the vehicle from computations of longitudinal and latitudinal velocities, tire slip ratios, clutch torque, axle torque, brake torque, and slip angles derived from the data sensed by the sensors from the wheel and steering movements. Finally, formulating a model of vehicle dynamics by using estimations of vehicle states with a target function to provide analytical data to enable the model of vehicle dynamics to be optimized and for using the data associated with the model which has been optimized to change control outputs to improve in real-time the vehicle dynamics.

Abstract: Systems and methods are provided testing a vehicle braking system. The method includes determining a nominal brake system parameter of the brake system during a braking operation. A first testing brake operation is performed and a first brake system parameter is determined based on the first testing brake operation. A tested brake system parameter is determined based on the first testing system parameter and the tested brake system parameter is compared to the nominal brake system parameter. A brake system compliance suspicion value of the vehicle braking system is then set based on the comparison.
