    Abstract: A method of controlling braking in an adaptive cruise control (ACC) of a vehicle. The method includes determining that braking is needed, including determining an amount of braking force needed, providing an indication to the brake system that braking is needed, filling the brake system with brake fluid at a predetermined rate to reduce pump noise, setting a delay equal to the amount of time needed to fill the brake system with fluid, applying a brake pad to a brake disc at the amount of braking force needed after waiting the delay, comparing the amount of braking force needed to the amount of braking force actually occurring, and reducing the delay to zero when the amount of braking force needed is less than or equal to the amount of braking force actually occurring.

    Abstract: A method of operating a hydraulic brake system is described. A method of operating a hydraulic brake system of a motor vehicle having a mechatronic brake booster to boost a hydraulic pressure generated in a brake master cylinder of the brake system by a brake pedal of the motor vehicle determines whether a propulsion request is present during operation of the motor vehicle and actuates the mechatronic brake booster when a propulsion request has ended or been substantially reduced. During a predetermined time interval after the propulsion request has ended or been reduced, the mechatronic brake booster is operated at a minimum intensity such that no braking effect occurs during the predetermined time interval, unless a braking request occurs.

    Abstract: For a vehicle having a brake system, a driver assistance system includes a detection system having at least one sensor configured to output measurement signals, and a control unit configured to receive at least one measurement signal, determine whether the vehicle is in a critical state based on measurement signal(s), and output an external brake request signal to a brake control device of the brake system for priming or biasing the brake system when the vehicle is determined to be in the critical state. The external brake request signal comprises an acceleration setpoint value signal having a higher acceleration setpoint value than a current actual acceleration value of the vehicle.

    Abstract: A system and method for providing mechanical time dilation by pre-braking a vehicle in the event there is a collision threat so as to reduce or eliminate the need for full automatic braking if the collision becomes imminent. The system calculates a time dilation deceleration to either maintain a time to collision at a previous value before the calculation or at a predetermined value. The system also estimates a projected closing speed of the vehicle to the object at a distance that would require full automatic braking to prevent a collision. The system then determines whether the time dilation deceleration is greater than a decelerating threshold and, if so, provides automatic vehicle braking at the threshold until the vehicle comes to a full stop. If the time dilation deceleration is not greater than the threshold, then the system provides automatic braking to decelerate the vehicle at the time dilation deceleration.
