The invention discloses a device for detecting air brake systems of vehicles. The device comprises a plurality of brake air chambers, a plurality of air storage barrels, a vehicle control unit, wheel speed sensors, a brake pedal sensor and alarms. The air storage barrels are connected with the brake air chambers by brake pipelines; the wheel speed sensors are mounted in hubs of four wheels, are electrically connected with the vehicle control unit by wheel speed sensor signal lines and are used for detecting wheel speeds of the wheels and then transmitting wheel speed signals to the vehicle control unit; the brake pedal sensor is mounted on a brake pedal, is electrically connected with the vehicle control unit by a brake pedal signal line and is used for detecting displacement signals of the brake pedal and transmitting the displacement signals to the vehicle control unit; the alarms are electrically connected with the vehicle control unit by alarm signal lines and are used for giving an alarm for air leakage of the brake pipelines. The invention further discloses a method for detecting the air brake systems of the vehicles by the aid of the device.
Description
technical field [0001] The invention relates to the field of vehicle air pressure braking, in particular to a detection device and detection method for a vehicle air pressure braking system. Background technique [0002] As a dynamic braking system, the pneumatic braking system is easier than the human hydraulic braking system to meet the requirements of large braking force under the condition that the pedal force is not too large and the pedal stroke is not too long. The pneumatic braking system is still widely used. Applied to medium-sized or above trucks or passenger cars. However, due to the existence of many air pressure pipelines and air pressure control components in the air pressure brake system, the air pressure brake is prone to air leakage, resulting in a braking force that cannot meet the expected requirements. In the case that the driver does not find out in time, especially when the car brakes suddenly at a high speed, the slip distance is too long, thus causi...
