Title:
CONFIGURATION CONTROL METHOD AND CONTROL SYSTEM FOR ELECTRONIC MECHANICAL BRAKE-BY-WIRE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/065709
Kind Code:
A1
Abstract:
A configuration control method for an electronic mechanical brake-by-wire system, for a dual-synchronous motor electronic mechanical brake-by-wire system configuration. An output shaft of a first motor in the configuration is connected to a first torque sensor; an output shaft of a second motor is connected to a second torque sensor; the first torque sensor and the second torque sensor are both electrically connected to an electric control unit; output shafts of the first torque sensor and the second torque sensor are both connected to a brake actuator. The control method comprises: acquiring a first actual output torque measured by the first torque sensor and a second actual output torque measured by the second torque sensor; if the received signal is a brake loading signal, respectively comparing a first difference value with an initial torque difference and a maximum torque difference when a motor fails to obtain a comparison result, the first difference value being the absolute value of the difference value between the first actual output torque and the second actual output torque; and controlling the first motor and the second motor according to the comparison result so as to complete brake loading by means of the brake actuator. Also disclosed is a configuration control system for an electronic mechanical brake-by-wire system. The control method and the control system can realize synchronous accurate control of a braking force.
