Method for operating a brake system with an automated parking brake
A method for operating a brake system with an automated parking brake for a motor vehicle, includes detecting a defined fault. The method further includes activating a parking mode of the parking brake automatically when the defined fault is detected. The automated parking brake is operable in different operating modes, a first operating mode corresponding to a drive mode and a second operating mode corresponding to the parking mode.
Haptic feedback for decoupled brake system
A vehicle braking system includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, a brake pressure generator for brake-by-wire braking, and a pedal feel simulator. In response to detecting impending wheel lock-up, a controller conducts an anti-lock braking routine during which the controller is programmed to create an artificial haptic feedback pulse to the brake pedal by opening a normally-open isolation valve between the master cylinder and the brake circuit to move a master cylinder piston until a compensation port opens.
BRAKE CONTROL UNIT
Towed vehicles can be extremely heavy. Accordingly, it is too much of a burden to the braking system of a towing vehicle to not have brakes on the towed vehicle. Controlling the brakes of the towed vehicle must be accurately applied otherwise very dangerous conditions can be created. A method of controlling braking of a towed vehicle is, therefore, needed. The method comprises receiving speed signals based on speed of a towing vehicle, or a towed vehicle, or both said towing vehicle and said towed vehicle, receiving pressure signals based on pressure of a hydraulic brake system of the towing vehicle, and generating a brake output signal based on the speed signals and the pressure signals.

Vehicle, Electronic Parking Brake System and Control Method Thereof
Provided are a vehicle, an electronic parking brake system and a control method thereof. The control method includes: controlling, when the electronic parking brake system is started, an electronic parking clamping force to be equal to a first preset value to perform parking braking on the vehicle; detecting the electronic parking clamping force and a current state of the vehicle; and when detecting that the vehicle moves, adjusting the electronic parking clamping force according to a magnitude relationship between the electronic parking clamping force and the first preset value to perform the parking braking on the vehicle again.
VEHICLE BRAKING CONTROL DEVICE
This vehicle braking control device executes automatic braking control to adjust a braking torque on the basis of a vehicle target deceleration value corresponding to a distance between the vehicle and an object in front of the vehicle, and executes anti-skid control to suppress excessive wheel slip by adjusting the braking torque on the basis of a wheel speed. The braking control device calculates an actual deceleration value corresponding to the target deceleration value, and executes feedback control on the basis of the target deceleration value and the actual deceleration value such that the actual deceleration value approaches the target deceleration value. The configuration is such that a control gain of the feedback control is reduced when anti-skid control is executed. Further, the configuration may be such that execution of feedback control is prohibited when anti-skid control is executed.
