Title:
車輪制御システムおよび車輪制御方法
Document Type and Number:
Japanese Patent JP7287011
Kind Code:
B2
Abstract:
A wheel control system (100) comprises: a motor control device (10) that controls control circuits; and a brake control device (120) that controls a brake of each wheel. The motor control device includes: a target torque instruction unit (16) that instructs a target torque to the control circuits; a failure occurrence identification unit (21) that identifies a failure occurrence in any of the control circuits; a detection result acquisition unit that acquires a detection result of at least one of a yaw rate and a lateral acceleration; and a target value calculation unit (19, 19a) that calculates a target value using detection results of a vehicle speed sensor (44) and a steering angle sensor (42). If a failure occurrence has been identified, the target torque instruction unit instructs zero as the target torque to the control circuit in which the failure has been identified, and the brake control device applies the brake to a wheel different from a driving wheel so that the detection results approach the target value.
