摘要： A method for identifying a fault in a brake assembly of a motor vehicle, including: ascertaining a first estimated value of a brake temperature based on an applied brake pressure; registering a series of measured temperature values by a temperature sensor spaced from the brake assembly; determining a second estimated value of the brake temperature based on the series of measured temperature values; comparing the first estimated value and the second estimated value; and deciding, based on the comparing of the first and second estimated values, whether there is a fault. Also described is a related motor vehicle braking system.

摘要： An electric disc brake system for a trailer. The brake system employs a caliper assembly that is attached to the trailer with floating fasteners, wherein the caliper assembly straddles an axle mounted rotor positioning an inner and outer brake pad adjacent to the rotor. A screw drive assembly is attached to the caliper. The assembly includes an electric motor coupled to a piston by a threaded shaft. The screw drive assembly converts rotation of the electric motor into linear motion to movement of the piston, wherein the inner and outer brake pads engage the rotor based upon the amount of pressure applied by the piston. A controller reacts to the pressure applied to a brake pedal to cause the electric motor to rotate in a clockwise or counter-clockwise direction.

摘要： A braking system for a vehicle includes a first axle attached to a chassis and rotatably supporting two front wheels, with a first brake including a first electronic brake controller for controlling application of braking to the front wheels. A second axle rotatably supports two rear wheels and is detachably connected to the chassis and has a second electronic brake controller and a second brake attached thereto for braking the rear wheels. Each of the electronic brake controllers has an independent power source. The system also includes an electronic park brake controller and parking brake. A vehicle control unit is in communication with each of the electronic brake controllers for coordinating control of the braking system. One or more communications network cables, which may be wired or wireless, connect the electronic brake controllers. An electrical connector allows for swapping the second axle, which requires no fluidic connections.

摘要： An electric hydraulic brake includes: wheel brakes configured to braking force to wheels of a vehicle; a reservoir storing brake oil; a master cylinder connected to the reservoir, and operated in conjunction with a main brake motor to generate pressure of the brake oil; a first controller configured to control the main brake motor; a hydraulic controller including a pump configured to form pressure of the brake oil in conjunction with an auxiliary brake motor, and a hydraulic block configured to selectively transmit the pressure of the brake oil formed in the master cylinder or the pump to the wheel brakes; and a second controller configured to control the auxiliary brake motor when the master cylinder or the first controller malfunctions. The hydraulic controller is provided with an auxiliary flow path to transmit the brake oil from the reservoir to the pump directly through the auxiliary flow path.

摘要： 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.

摘要： A controller includes a failure detection unit that detects a failure in a first power supply system, and a power supply system control unit that closes a relay in a case where an execution of an automatic parking function starts and, during the execution of the function, causes the first power supply system to supply power, without causing a second power supply system to supply power, to the electric brake device, by setting a target output voltage of the second power supply system lower than an output voltage of the first power supply system when the failure detection unit does not detect the failure, and operates the electric brake device by setting the target output voltage to a voltage within a range in which the electric brake device is operable when the failure detection unit detects the failure.

摘要： An electronic mechanical brake system and a vehicle. The electronic mechanical brake system includes a brake pedal, an electronic brake mechanism, a mechanical brake mechanism, a brake, and a switch mechanism with a first state and a second state. The electronic brake mechanism includes a controller and an electronic signal sensor. The controller, the electronic signal sensor, and the brake are electrically connected. When the switch mechanism is in the first state, the electronic signal sensor is configured to receive a braking signal of the brake pedal and transmit the braking signal to the controller. The controller controls the brake to brake based on the braking signal. The electronic mechanical brake system can improve driving safety. In addition, reliability of the mechanical brake system is high, and costs are low.
