Regulating motor vehicle braking system involves indication changeover from remotely actuated brake pressure source to driver operated source by haptic signaling via brake actuator

摘要

The brakes can be acted upon by a first, remotely actuated pressure source driven by an electronic controller that produces a signal corresponding to a driver's deceleration demand in accordance with brake actuator operation. The brakes can be acted upon by the hydraulic pressure of a second driver operated source. A transition from the first to the second pressure source is indicated by haptic signaling via the brake actuator. The wheel brakes can be acted upon by a first, remotely actuated pressure source driven by an electronic controller that produces a signal corresponding to a driver's deceleration demand in accordance with the operation of a brake actuator, preferably a brake pedal. The wheel brakes can be acted upon by the hydraulic pressure of a second pressure source operated by the driver. The driver is given an indication of a transition from the first, remotely actuated pressure source to the second, driver operated source by haptic signaling via the brake actuator.
