Abstract: A vehicle includes a brake-by-wire system having a brake pedal and first and second sensors. The first sensor is configured to output a first signal indicative of a position of the brake pedal and the second sensor is configured to output a second signal indicative of the position. A controller is programmed to command a braking torque based on only the first signal when a travel of the brake pedal is limited to a first range.

Abstract: The disclosure relates to a method for operating a motor vehicle which is capable of driving either under the control of a human driver who is located on board the motor vehicle or autonomously, at least over certain sections of a route, and which is able to avoid collisions, detect adverse effects on the driver and bring about emergency stops. Accordingly, the motor vehicle has an emergency braking assistant, and if an adverse effect on the driver is detected in the autonomous driving mode, a characteristic curve which is preset for emergency braking operations is changed in such a way that an emergency braking operation is initiated at an earlier point and the braking force is built up more slowly than in the non-autonomous driving mode.

Abstract: A method is provided for operating an electromechanical vehicle brake system having an ESP module and at least two brake circuits, each brake circuit comprising high and low pressure switching valves, a low pressure storage device, and two wheel brakes. The method comprises, in advance of a possible breaking procedure and based on a trigger factor, filling the low pressure storage device with an amount of brake fluid at a first pre-pressure. Subsequently, an ESP pump is used to fill the vehicle brake system, including the low pressure storage device, with an adjustable amount of final pre-pressure. All valves are closed when the final pre-pressure is achieved. The method further comprises, during a braking procedure, opening respective inlet valves of the wheel brakes and supplying at least a part of the final pre-pressure to at least one wheel brake of the vehicle brake system.

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: A vehicle includes a brake-by-wire system having a brake pedal and a first sensor configured to output a signal indicative of a position of the brake pedal. A controller is in communication with the sensor and is programmed to enable and disable a one-pedal driving mode based on a user-selected setting. The controller is further programmed to, in response to the signal of the first sensor being valid and the one-pedal driving mode being disabled, enable the one-pedal driving mode regardless of the user-selected setting.

Abstract: Systems and methods are described for reducing brake drag in a brake system of a vehicle. It may be determined that the vehicle is stationary. A brake pressure of the brake system may be monitored. The monitored brake pressure may then be compared to a brake pressure criteria. A brake pressure to be applied may be regulated when the monitored brake pressure does not meet the brake pressure criteria, wherein the applied brake pressure meets the pressure criteria.
