Patent number: 11904828Abstract: A stability control system of a vehicle utilizing an electronic control unit that minimizes rollback of a vehicle as a result of wheel slip immediately following a hill start assist operation. The electronic braking control module controls actuation and de-actuation of vehicle brakes on an inclined surface. Immediately following a hill start assist operation on the inclined surface after each wheel brake is de-actuated for allowing forward movement of the vehicle up the hill, a split-mu road surface condition is detected in response to sensing wheel slip for each of the wheels. The electronic control unit determines a respective undriven, or non-dominant driven, wheel having the highest coefficient of friction among the undriven, or less dominant driven wheels, as determined by the wheel speeds.Type: GrantFiled: December 26, 2018Date of Patent: February 20, 2024Assignee: ZF Active Safety US Inc.Inventor: Shawn Hawley

Patent number: 11173885Abstract: A stability control system of a vehicle utilizing an electronic control unit that detects a yaw condition while each of the wheel brakes are actuated by EBCM and the wheel speeds are zero. An electronic control unit includes an electronic braking control module that controls actuation and de-actuation of vehicle brakes on an inclined surface. A yaw condition is identified while all vehicle brakes are actuated on the inclined surface and each wheel speed is zero. The electronic control unit identifies which uphill wheel is leading a direction of the yaw and identifies a wheel of an opposing axle diagonal to the identified uphill wheel. The electronic control unit in cooperation with the electronic braking control module de-actuates the vehicle brakes of the identified uphill wheel and diagonal wheel to increase a side friction to the identified diagonal wheels to reduce further yawing of the vehicle.Type: GrantFiled: December 26, 2018Date of Patent: November 16, 2021Assignee: ZF Active Safety US Inc.Inventors: Shawn Hawley, Arun Varadarajan

Patent number: 11091136Abstract: A method of controlling the fluid pressure at wheel brakes of a brake system, the method comprising: (a) providing a brake system capable of delivering fluid pressure to the wheel brakes during an autonomous braking event, and wherein the brake system includes a brake pedal and sensor for sensing a driver's braking intent when applying force to the brake pedal; (b) controlling the fluid pressure at the wheel brakes at a predetermined pressure during an autonomous braking event, wherein the sensor detects no depression of the brake pedal; (c) cancelling the autonomous braking event when the sensor detects depression of the brake pedal; and (d) subsequently to step (c), the brake system enters into a handoff procedure to maintain the predetermined pressure at the wheel brakes after the sensor senses the brake pedal being depressed when a requested pressure by the driver is less than the predetermined pressure.Type: GrantFiled: August 21, 2019Date of Patent: August 17, 2021Assignee: ZF Active Safety US Inc.Inventors: Wenbo Yu, Shawn Hawley
