Title:
STEERING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/195444
Kind Code:
A1
Abstract:
This steering control device controls, for a vehicle (100) in which three or more wheels (91-94) not mechanically bound to each other can be steered independently, steering of each of the wheels. Steering actuator control parts (601-604) are provided in correspondence with a plurality of steering actuators (71-74) that respectively steer the wheels, and control drive currents such that steering angles output by the steering actuators (71-74) reach desired values. A reaction actuator control part (56) controls driving of a reaction actuator (57) in a steering mechanism of a steer-by-wire system. The steering actuator control parts (601-604) and the reaction actuator control part (56) perform communication on driving limit information, and limit, on the basis of the driving limit information, driving of the steering actuators (71-74) and the reaction actuator (57).
