Abstract
A steering assist device that appropriately controls swaying of a vehicle body while a rider is walking by pushing the vehicle body by the hands and thereby eliminates the anxiety of the rider about the support of the vehicle body. A steering assist device includes a steering actuator that provides an assist torque that generates a steering angle of a steered wheel to a suspension device that supports the steered wheel; roll angle detector that detects a roll angle of a vehicle body; and controller that controls the assist torque provided by the steering actuator based on the roll angle of the vehicle body and a target roll angle. The controller sets the roll angle of when the vehicle body is inclined from an upright state to the target roll angle.
Claims4
A steering assist device, comprising:
- a steering actuator that provides an assist torque that generates the steering angle of the steered wheel to a suspension device that supports the steered wheel;
- a vehicle body acceleration sensor that detects a roll angle that is an angle of inclination of a vehicle body in a roll direction;
- processor that controls the assist torque provided by the steering actuator based on the roll angle of the vehicle body and a target roll angle that is a target value of the roll angle;
- and
- a mode selection switch sensor that detects operation on a mode selection switch for selecting a push-walking mode,
- wherein
- when vehicle speed is equal to or more than a prescribed vehicle speed threshold indicating a start of push-walking, the processor sets the target roll angle, and sets the roll angle of when the vehicle body is inclined from an upright state, to the target roll angle, and
- when the push-walking mode is selected by the operation of the mode selection switch, the processor provides the assist torque.
