Smart vehicle systems and control logic for active brake drag mitigation of electromechanical brake systems

Abstract

Presented are smart vehicle systems provisioning active brake drag control, methods for making/using such systems, and vehicles equipped with such systems. A method of operating a motor vehicle with a brake-by-wire (BBW) system includes a vehicle controller determining whether or not the vehicle is traveling in a forward direction. If so, the controller responsively retrieves advanced driver assistance system (ADAS) data and driving torque request data to determine if an ADAS warning event is detected or an acceleration torque request was received to accelerate the motor vehicle. The controller commands an electric motor of the BBW brake system to drive a brake actuator and thereby change a running clearance (RC) between a brake pad and a brake rotor to a reduced RC responsive to detecting the ADAS warning event or to an increased RC responsive to receiving the acceleration request to accelerate the motor vehicle.
