A braking system for a vehicle includes a hydraulic vehicle brake with an electric actuator and an electromechanical braking device. The braking system further includes a locking mechanism configured to lock the electric actuator.

According to at least one embodiment, the present disclosure provides a method of controlling a brake of a vehicle, the method comprising: a process of determining a pressure difference between channel pressure, which is determined by hydraulic pressure of the wheel brake, and required braking pressure by means of the controller; a process of opening the control valve by means of the controller when the channel pressure is larger than the required braking pressure; and a process of controlling the control valve on the basis of the difference between the required braking pressure and the channel pressure.

In order to detect air in a brake master cylinder within a hydraulic power brake system, a brake master cylinder pressure on actuation of the brake master cylinder is compared with a comparison pressure which prevails in the brake master cylinder when it is air-free. For bleeding, brake fluid is conveyed with a power brake pressure generator through the in this case non-actuated brake master cylinder into a pressureless brake fluid reservoir, where air escapes from the brake fluid.

A method performed by a control unit for handling safe stop mode of a vehicle. The control unit obtains an activation request for activating the safe stop mode. When the activation request has been obtained, the control unit verifies that all safety conditions of the vehicle are fulfilled. The control unit activates the safe stop mode when the activation request has been obtained and when all safety conditions are fulfilled. The control unit triggers at least one light source to be turned on when all safety conditions are fulfilled. After the safe stop mode has been activated, the control unit obtains an inactivation request for inactivating the safe stop mode of the vehicle. The control unit inactivates the safe stop mode of the vehicle when the inactivation request has been obtained.

The present disclosure relates to a control method of a brake system including a reservoir in which oil is stored, wherein the control method includes detecting a first level of a liquid level of oil stored in the reservoir, detecting a second level of the liquid level of oil stored in the reservoir, determining a decrease trend of an oil amount stored in the reservoir based on a time point when the first level is detected and a time point when the second level is detected, and limiting at least one additional function based on the decrease trend of the oil amount.

A valve arrangement is inserted between a master brake cylinder and a reservoir in a housing of an electrohydraulic motor vehicle brake system which can be activated both by a vehicle driver and independently of the vehicle driver. The valve arrangement can be acted on by a volume flow which can be conveyed by a linear actuator in the direction of a pedal travel simulator, the working chamber of the pedal travel simulator being connected to the master brake cylinder, wherein, for the purpose of simplified construction and actuation, the valve arrangement has a hydraulically actuable non-return valve and a fixed diaphragm arranged parallel to the non-return valve. The non-return valve is arranged together with the fixed diaphragm in a valve carrier which is fastened to a closure plug which closes the housing of the motor vehicle brake system.

A parking brake for a wheel rotor having a brake pad associated therewith includes a housing defining first and second passages. First and second pistons are provided in the respective first and second passages. Spindles extend into and are connected with each piston. A clutch unit is connected to the spindles and includes a motor. The clutch unit has a first condition allowing for rotation of the spindles in response to hydraulic pressure applied to the pistons such that the pistons are axially movable within the passages and relative to the spindles into engagement with the brake pad. The clutch unit has a second condition for rotating the spindles to drive the pistons into the brake pad and apply the parking brake.

This application provides a torque compensation method for a vehicle, a torque compensation apparatus of a vehicle, and an associated computer-readable storage medium. The torque compensation method includes: when a vehicle control module determines that the vehicle is in a sliding state during a brake idle stroke, obtaining, by the vehicle control module, a pressure of a brake master cylinder of the vehicle, and controlling a motor of the vehicle based on the pressure of the brake master cylinder to output a compensation torque. In this application, a range of the brake idle stroke of the vehicle can be precisely determined, so as to control the motor of the vehicle to output the compensation torque in a timely manner, thereby effectively suppressing sliding during the brake idle stroke of the vehicle and ensuring safe driving.

The present disclosure provides an electronic hydraulic brake system that can appropriately provide redundancy braking force, that is, an electronic hydraulic brake system that provides a so-called redundancy function, in the situation in which a driver does not drive or gives less attention to driving such as autonomous driving or smart cruise control and a main braking device malfunctions.

An electric hydraulic brake includes: wheel brakes configured to supply braking force to wheels of a vehicle; a main braking unit including a reservoir which stores brake oil, and a master cylinder configured to form pressure of the brake oil in conjunction with a main brake motor; and a hydraulic controller comprising at least one pump configured to pump the brake oil in conjunction with an auxiliary brake motor, and configured to selectively transmit the pressure of the brake oil formed in the master cylinder or the pump to the wheel brakes. The hydraulic controller includes at least one auxiliary flow path which is connected at a first end thereof to the reservoir and is connected at a second end thereof to an inlet of the pump to transmit hydraulic pressure from the reservoir to the pump directly through the at least one auxiliary flow path.
