Abstract
Systems and methods are described for controlling a vehicle braking system. An electronic controller determines a target deceleration based at least in part on a detected displacement position of a brake pedal and determines an adjusted braking pressure to be applied to at least one wheel of the vehicle such that, regardless of the displacement position of the brake pedal and the target deceleration, the adjusted braking pressure is maintained outside of a defined range of braking pressures that corresponds to a NVH condition for the at least one wheel. The adjusted braking pressure is then applied to the at least one wheel of the vehicle.
Claims20
A brake system for a vehicle comprising:
- a brake pedal position sensor configured to detect a displacement position of a brake pedal of the vehicle;
- and
- an electronic controller configured to
- determine a target deceleration based at least in part on the detected displacement position of the brake pedal,
- determine an adjusted braking pressure to be applied to at least one wheel of the vehicle, wherein the adjusted braking pressure is maintained outside of a defined range of braking pressures corresponding to a NVH condition for the at least one wheel, and
- transmit a signal to a braking actuator configured to cause the braking actuator to apply the adjusted braking pressure to the at least one wheel of the vehicle.
A method for controlling a vehicle braking system, the method comprising:
- determining, by an electronic controller, a target deceleration based at least in part on a detected displacement position of a brake pedal;
- determining, by the electronic controller, an adjusted braking pressure to be applied to at least one wheel of the vehicle, wherein the adjusted braking pressure is maintained outside of a defined range of braking pressures corresponding to a NVH condition for the at least one wheel;
- and
- applying the adjusted braking pressure to the at least one wheel of the vehicle.
