Document Type and Number:
WIPO Patent Application WO/2021/075054
Kind Code:
A1
Abstract:
A travel assistance device comprises a sensor that detects a steering angle of a steering wheel 2 installed in a vehicle, and a controller that, on the basis of the steering angle detected by the sensor, determines when an occupant of the vehicle overrides travel assistance control during travel in the vehicle. The controller detects a first motor current for canceling self-aligning torque generated in the tires installed in the vehicle during the execution of travel assistance control, sets a first threshold value greater than the first motor current using the first motor current, and determines that overriding has occurred when a second motor current for controlling the turning angle of the tires in accordance with the steering angle is greater than the first threshold value.
