Title:
VEHICLE ANTI-SKID CONTROL METHOD, FIRST ANTI-SKID HOST, SECOND ANTI-SKID HOST, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/033413
Kind Code:
A1
Abstract:
A vehicle anti-skid control method, a first anti-skid host (501), a second anti-skid host (502), and a system. The first anti-skid host (501) determines first fault information according to a first host state, first channel states of dual-channel speed sensors (503), and first coil group states of anti-skid exhaust valves (504); if the first fault information indicates that the first host and a device connected thereto are normal, the first host (501) sends a first normal signal to the second host (502), and controls a first anti-skid exhaust valve and a second anti-skid exhaust valve according to the speed of a bogie axle; if the first fault information indicates that the first host or the device connected thereto are abnormal, the first host (501) sends a first fault signal to the second host (502), and upon receiving a second normal signal sent by the second host (502), sends a transfer signal to the second host (502), so that the second host (502) takes over all the anti-skid exhaust valves (504). Configuring twin anti-skid hosts to perform vehicle anti-skid control on a railway vehicle improves the usability and safety of the railway vehicle.
