Abstract

A vehicle system includes: a steering device including an operation member, a turning member mechanically separated from the operation member and configured to turn a wheel, a reaction force actuator configured to apply a reaction force to the operation member, and a turning actuator configured to drive the turning member; a controller; and a display device. The controller is configured to determine whether a steering angle of the operation member and a turning angle of the wheel are in a phase deviation state, and cause the display device to perform a guidance display and an actual state display in a case where the steering angle and the turning angle are in the phase deviation state, the guidance display prompting a driver to perform an operation for phase matching to improve the phase deviation state, the actual state display indicating an actual turning state of the wheel.

First claim

The invention claimed is:

1. A vehicle system, comprising:
a steering device including an operation member configured to be operated by a driver, a turning member mechanically separated from the operation member and configured to turn a wheel, a reaction force actuator configured to apply a reaction force to the operation member, and a turning actuator configured to drive the turning member;
a controller configured to perform control relating to the steering device; and
a display device configured to display information on the steering device,
wherein the controller is configured to
determine whether a steering angle of the operation member and a turning angle of the wheel are in a phase deviation state, and
cause the display device to perform a guidance display and an actual state display in a case where the steering angle of the operation member and the turning angle of the wheel are in the phase deviation state, the guidance display prompting the driver to perform an operation for phase matching to improve the phase deviation state, the actual state display indicating an actual turning state of the wheel,
wherein the controller is configured to cause the display device to display a first operation member image and a second operation member image in a superimposed state, the first operation member image indicating a current state of the operation member, the second operation member image indicating a target state of the phase matching.

2. The vehicle system according to claim 1 , wherein the controller is configured to cause the display device to display a captured image as the actual state display, the captured image being captured by a camera configured to capture a lateral side of a vehicle body including the wheel.

3. The vehicle system according to claim 1 , wherein the display device is configured to
display a captured image captured by a camera configured to capture a front of a vehicle body, and
display a prospective trajectory line as the actual state display on the captured image, the prospective trajectory line indicating a travel direction of a vehicle.

4. The vehicle system according to claim 1 , wherein the display device includes a plurality of light emitting portions arranged in one direction, and
the display device is configured to display both the turning angle and the steering angle as the actual state display by changing a light emitting state of the plurality of light emitting portions.

5. The vehicle system according to claim 1 , wherein in a case where the phase matching is completed, the controller causes the display device to perform a completion display indicating that the phase matching is completed.

6. The vehicle system according to claim 1 , wherein the display device is provided in the operation member, and
the controller is configured to control the operation member so as to keep a screen direction constant even when the operation member rotates, the screen direction being a direction of a screen displayed on the display device.

7. The vehicle system according to claim 1 , wherein the operation member includes a vibrating portion arranged at least on each of left and right sides of a center of the operation member, and
in the phase deviation state, the controller vibrates the vibrating portion at a position corresponding to an operation direction of the operation member for the phase matching.

8. A vehicle system, comprising:
a steering device including an operation member configured to be operated by a driver, a turning member mechanically separated from the operation member and configured to turn a wheel, a reaction force actuator configured to apply a reaction force to the operation member, and a turning actuator configured to drive the turning member;
a controller configured to perform control relating to the steering device; and
a display device configured to display information on the steering device,
wherein the controller is configured to
determine whether a steering angle of the operation member and a turning angle of the wheel are in a phase deviation state, and
cause the display device to perform a guidance display and an actual state display in a case where the steering angle of the operation member and the turning angle of the wheel are in the phase deviation state, the guidance display prompting the driver to perform an operation for phase matching to improve the phase deviation state, the actual state display indicating an actual turning state of the wheel,
wherein in the phase deviation state, the controller controls the reaction force actuator such that the reaction force applied to the operation member acts as a frictional reaction force that does not apply a restoring force to the operation member, and
when the phase matching is completed, the controller controls the reaction force actuator so as to reduce the reaction force applied to the operation member.

9. A vehicle system, comprising:
a steering device including an operation member configured to be operated by a driver, a turning member mechanically separated from the operation member and configured to turn a wheel, a reaction force actuator configured to apply a reaction force to the operation member, and a turning actuator configured to drive the turning member;
a controller configured to perform control relating to the steering device; and
a display device configured to display information on the steering device,
wherein the controller is configured to
determine whether a steering angle of the operation member and a turning angle of the wheel are in a phase deviation state, and
cause the display device to perform a guidance display and an actual state display in a case where the steering angle of the operation member and the turning angle of the wheel are in the phase deviation state, the guidance display prompting the driver to perform an operation for phase matching to improve the phase deviation state, the actual state display indicating an actual turning state of the wheel,
wherein the controller is configured to
acquire information on an output state of the turning actuator,
acquire information on the phase deviation state,
determine whether the phase deviation state can be improved within a prescribed period by a driving force of the turning actuator based on the information on the output state and the information on the phase deviation state, and
cause the display device to perform the guidance display and the actual state display upon determining that the phase deviation state cannot be improved within the prescribed period.
