Title:
VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/138494
Kind Code:
A1
Abstract:
This vehicle comprises a body, N (an integer of three or more) number of vehicle wheels including at least one turning wheel capable of turning in the width direction of the body and including left and right drive wheels, a drive system, a steering drive device, an inclination device, an inclination drive device, a vehicle speed sensor, a vehicle wheel angle sensor, an operation input unit, and a control device. When a condition is met which includes the vehicle speed being less than a first threshold and the state of the steering drive device being a problematic state, the control device controls the difference between a left torque, which is the torque of the left drive wheel applied by the drive system, and a right torque, which is the torque of the right drive wheel, so that the vehicle wheel angle approaches a target vehicle wheel angle.
