A method for operating a hydraulic brake system of a motor vehicle includes enabling a parking brake function by actuating a pressure generator and an actuator such that the pressure generator and the actuator together generate a total clamping force at a wheel brake, and actuating the pressure generator based on a movement of an actuator element and/or a brake piston, the movement generated by the actuator. The brake system includes the wheel brake having the brake piston, a brake pedal device, the pressure generator configured to actuate the wheel brake, the actuator assigned to the wheel brake and having the actuator element configured to actuate the wheel brake. A force that displaces the brake piston in order to actuate the wheel brake is generated by the pressure generator and/or the actuator.

The invention relates to a method for controlling a braking system for setting a total braking torque distribution between a first and a second axle of a motor vehicle. The braking system includes a friction braking device and a recuperative braking device. The braking system has a total braking torque composed of a friction braking torque portion and a recuperative braking torque portion. The method include determining, for one axle, a minimal recuperation torque, which is set on that axle, and remains set on that axle for all driving situations as a recuperative braking torque portion.

An automatic braking system and method are provided for controlling the automatic operation of a pneumatic (air) brake system installed on commercial highway vehicles and the like, particular heavy trucks and buses. When a possible collision is detected or an object is detected in proximity to at least one side and/or end of the vehicle, the system automatically operates the existing, factory installed air braking system of the vehicle to avoid a collision or mitigate the collision impact by concurrently pressurizing each of the rear and front pneumatic service brakes of the vehicle. Pressing the existing vehicle brake pedal deactivates the automatic braking system, thereby permitting the driver to take over control of braking at any time.

A brake control device and a brake system are configured to appropriately apply a braking force to a rotary body of a human-powered vehicle. The brake control device includes an electronic controller that controls a braking portion electrically driven to brake a rotary body rotating in accordance with traveling of a human-powered vehicle. The electronic controller controls the braking portion in accordance with an operation amount of an operating device and a state related to the human-powered vehicle.

A trailer control valve for a tractor includes a body defining a supply port and first and second delivery ports. The supply port is configured for fluid communication with a fluid source on the tractor. The first and second delivery ports are configured for fluid communication with glad-hand connectors through which fluid is supplied from the tractor to a trailer. A pressure sensing solenoid receives fluid signal from each of the first and second deliver ports and selectively passes fluid signal therefrom to a pressure sensor as a function of a brake control signal received by a controller that controls the pressure sensing solenoid.

Provided are a vehicle braking apparatus, a vehicle braking method, and a vehicle braking system, which improve the responsiveness of a braking force of a vehicle. The vehicle braking apparatus includes a braking torque generating mechanism configured to generate a braking torque in a first braking torque imparting portion that imparts a braking torque to a first wheel portion comprising either front or rear wheels of the vehicle and a second braking torque imparting portion that imparts a braking torque in a second wheel portion comprising the other ones of the front and rear wheels. The vehicle braking apparatus further includes a control mechanism configured to output to the braking torque generating mechanism a command for generating the braking force precedentially in the second wheel portion selected according to a condition of a vehicle as a wheel portion in which the braking force should be precedentially generated.
