Title:
VEHICLE TRAVEL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/085249
Kind Code:
A1
Abstract:
A vehicle travel control device (10) controls travel of an independent steering vehicle (100) in which at least three tires (91-94) can be independently steered. A turn instruction unit (11) instructs a turn during normal travel. A pivot turn instruction unit (12) instructs, with a target instruction value, a pivot turn in which one tire serves as a pivot center and other tires are driven during turning of the vehicle. A steering angle control unit (15) and a braking force control unit (16) obtain vehicle characteristics from a vehicle characteristics storage device (20). In accordance with the center of the pivot turn instructed by the pivot turn instruction unit (12), the steering angle control unit (15) individually steers each tire (91-94), and the braking force control unit (16) individually brakes each tire (91-94). The steering angle control unit (15) and the braking force control unit (16) calculate the steering angle and the driving direction of each tire from the target instruction value, to pivotally turn the vehicle.
