The present disclosure provides an auto-braking system which includes a braking device, a receiver, and a controller. The controller includes a determining portion, a verifying portion and an executing portion. The determining portion determines whether a vehicle will violate a red signal of the traffic light based on the traffic light state information. The verifying portion verifies the traffic light state information is valid by comparing the traffic light state information with the image of the traffic light captured by the sensor. The executing portion executes a first braking control to slow the vehicle at a first deceleration rate when the determining portion determines that the vehicle will violate a red signal. The executing portion executes a second braking control to slow the vehicle at a second deceleration rate to stop at a specified position when the verifying portion verifies that the traffic light state information is valid.

A method for operating a braking system of a motor vehicle equipped with a wheel-slip control device, wherein the braking system includes an electrohydraulic service brake, set to generate braking forces independently of an actuation by an operator. The system having a mechanical or electromechanical parking brake actuated by an actuating element, and acting, in particular, on the rear wheels of the motor vehicle. An operator-side intent to actuate the parking brake is recognized and subsequently during the actuation of the parking brake a hydraulic pressure of the service brake is generated that acts on at least one rear wheel, of the motor vehicle is capable of being braked by the parking brake. The hydraulic pressure sufficient to assist the parking brake and correspondingly lock the rear wheel of the motor vehicle braked by the parking brake during travel of the motor vehicle.

In one example, brake line pressure is increased at a same rate after brake booster vacuum is exhausted as before brake booster vacuum is exhausted so that a driver experiences a continuous braking force.

A method of preventing a sensitive brake for preventing an excessive brake of a vehicle may include measuring conditions for determining a sensitive brake environment of a vehicle, terminating a brake when the conditions measured do not correspond to a preset sensitive brake environment, and when the conditions correspond to the sensitive brake environment, controlling a brake apparatus of the vehicle to be operated in a sensitive brake preventing mode, executing a first brake in a sensitive brake mode, comparing whether a value of an index of deceleration to a pedal effort at the first brake executed in the sensitive mode is larger than a predetermined value, and terminating the brake when the value of the index is smaller than the predetermined value, and repeatedly performing the brake in the sensitive brake mode when the value of the index is larger than the predetermined value.

When braking force is applied to a vehicle by the operation of a brake actuator, this control device, which is a vehicle brake control device, calculates the time to stop TTS on the basis of the relationship between the vehicle speed VS and the vehicle deceleration DVS. In addition, when the calculated time to stop TTS becomes less than a restriction determination time TTSTH, the control device stops the operation of the supply pumps of the brake actuator.
