Embodiment Construction
[0019] refer to figure 1 The specific embodiment of the present invention includes two electronic brake control units and two pressure sensors. The first pressure sensor 1 and the second pressure sensor 2 are both arranged on the pipeline of the parking brake cylinder. cylinder line pressure. The first pressure sensor is connected to the first electronic brake control unit 3, and the first electronic brake control unit collects the pressure information of the first pressure sensor to judge the state of the parking brake, and at the same time analyzes the state of the first pressure sensor. The second pressure sensor is connected to the second electronic brake control unit 4, and the second electronic brake control unit collects the pressure information of the second pressure sensor to judge the state of the parking brake, and at the same time analyzes the state of the second pressure sensor. The first electronic brake control unit and the second electronic brake control unit ...
