Title:
WHEEL-TURN CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023136085
Kind Code:
A
Abstract:
To provide a wheel-turn control device that ensures an appropriate vehicle control capability when the drive of any one of wheel-turn actuators is restricted in an independent wheel-turn vehicle with equal to or greater than three wheels.SOLUTION: A wheel-turn control device 501 controls, in a vehicle 100 that has equal to or greater than three wheels 91 to 94 which are independently turnable and which are not mechanically constraint from each other, the turn of each wheel. Wheel-turn actuator control units 601 to 604 are provided so as to correspond to multiple wheel-turn actuators 71 to 74 that turn the corresponding wheel, and controls a drive current in such a way that the turn angles output by the wheel-turn actuators 71 to 74 become a desired value. A set of the wheel-turn actuator corresponding to each wheel and the corresponding wheel-turn actuator control unit is represented as a unit. The plurality of wheel-turn actuators 601 to 604 communicate, with each other, drive restrict information that is information relating to the drive restriction of each of the wheel-turn actuators 71 to 74, and restricts the drive of the wheel-turn actuator of the own unit on the basis of the drive restrict information of the own unit and that of the other units.SELECTED DRAWING: Figure 1
