Under such a background, the publication number is [CN106458196A], which is called the brake pressure modulator of the electronic brake system of commercial vehicles, which discloses a kind of integration of two independent pressure regulation loops and a common electronic control module. In the common structural unit, the purpose is to reduce the cost and integrate the structure, but there is only one set of redundant control paths in the pressure regulation circuit, and the other pressure regulation circuit cannot perform smooth and reliable braking in the case of electronic control failure.

The invention discloses a double-channel air pressure adjusting device for an electric control brake system and a control method thereof. The device comprises two pressure adjusting loops and a commonelectric control unit, wherein the pressure adjusting loops can be independently adjusted through the electric control unit; the first pressure adjusting loop is provided with a first exhaust path, and the second pressure adjusting loop is provided with an exhaust path; the first pressure adjusting loop and the second pressure adjusting loop have a common redundancy control pressure path; the redundant control pressure path adjusts electromagnetic valves and control valves on the first pressure adjusting loop and the second pressure adjusting loop; two pressure adjusting loops are integratedinto one module, a redundancy control pressure path is shared, and respective redundancy control valves are arranged on the two pressure adjusting loops; under the condition that an electronic brakingsystem breaks down, a wheel brake on an axle can be braked or released under the condition that electronic adjustment is abandoned through a redundant control pressure path. The device has the advantages of being simple and compact in structure, low in cost and high in reliability.
Description
technical field [0001] The invention belongs to the technical field of vehicle braking, and in particular relates to a dual-channel air pressure regulating device for an electronically controlled braking system and a control method thereof. Background technique [0002] The electronic control braking system realizes the precise calculation of the vehicle, sends the output signal of the braking signal generator to the controller, and the controller sends the braking command to the braking device to achieve stable braking of the vehicle. Under such a background, the publication number is [CN106458196A], which is called the brake pressure modulator of the electronic brake system of commercial vehicles, which discloses a kind of integration of two independent pressure regulation loops and a common electronic control module. In the common structural unit, the purpose is to reduce the cost and integrate the structure, but there is only one set of redundant control paths in the pre...
