Title:
VEHICULAR STEERING CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022022847
Kind Code:
A
Abstract:
To accomplish, in a steer-by-wire type steering device, a variable control on a steering angle ratio while suppressing the complication of the control and the increase of a process load.SOLUTION: A steer-by-wire type vehicular steering device includes: an aiming steering torque calculating unit 200 that calculates an aiming steering torque; a steering reaction force control unit 300 that controls a reaction force actuator which applies steering reaction force torque to a steering wheel on the basis of actual steering torque and the aiming steering torque; an aiming turning angle calculating unit 400 that calculates the aiming turning angle of turn wheels 8L and 8R on the basis of the steering angle; a mode changing unit 100 that changes the running mode of a vehicle; a turning angle converting unit 501 that sets a turning angle gain in accordance with the running mode; and a turning angle control unit 500 that controls a turning actuator which turns the turn wheels on the basis of a corrected aiming turning angle obtained by correcting the aiming turning angle by the turning angle gain and of the actual turning angle of the turn wheels.SELECTED DRAWING: Figure 10
