Abstract

A vehicle capable of stably turning by improving turning performance and that is able to ensure comfort by reducing a burden on a driver is provided.

A link mechanism is bent and stretched to incline both left and right wheels to the inside during a turn to generate camber thrust by side force and, as a result, turning force is increased. Further, when the link mechanism is bent and stretched, a coupling link is inclined and a passenger section is inclined, thus making it possible to move the center of gravity of the vehicle toward an inner wheel during a turn. By so doing, lift of the inner wheel during a turn is prevented to make it possible to improve turning performance. In addition, since the passenger section is inclined to the inner wheel side during a turn, it is possible to make a passenger experience less centrifugal force.

Claims

1. A control device used in a vehicle that includes a plurality of wheels and a camber angle adjusting device that adjusts camber angles of the wheels, wherein

the vehicle includes wheel state detecting device that detects a state of each of the wheels during travelling, and

the control device comprises:

determining section that determines whether there is a wheel that is likely to slip among the plurality of wheels, based on a comparison among the states of the respective wheels, detected by the wheel state detecting device; and

a camber angle adjusting section that, when it is determined by the determining section that there is the wheel that is likely to slip, actuates the camber angle adjusting device to adjust the camber angle of the wheel determined to be likely to slip so as to be inclined at a predetermined angle toward a negative side or a positive side.

2. The control device according to claim 1, wherein the determining section determines whether there is one wheel that is likely to slip among the plurality of wheels, based on a comparison among the states of the respective wheels, detected by the wheel state detecting device.

3. A vehicle by comprising:

a wheel;

a camber angle adjusting device that adjusts a camber angle of the wheel;

a wheel state detecting device that detects a state of the wheel; and

the control device according to claim 1, wherein

the wheel is configured so that a curvature radius of a tread surface is larger than a predetermined value, and

the camber angle adjusting device is configured so that a camber rotation axis of the wheel is set below a rotation axis of the wheel.

4. A vehicle comprising:

a wheel;

a camber angle adjusting device that adjusts a camber angle of the wheel;

a wheel state detecting device that detects a state of the wheel; and

the control device according to claim 1, wherein

the wheel is configured so that a curvature radius of a tread surface is smaller than a predetermined value, and

the camber angle adjusting device is configured so that a camber rotation axis of the wheel is set above a rotation axis of the wheel.

5. The vehicle according to claim 3, wherein the wheel state detecting device detects a rotational speed of the wheel.

6. The vehicle according to claim 3, wherein the wheel state detecting device detects a ground contact force on the wheel.

7. The vehicle according to claim 3, further comprising a suspension that suspends the wheel on a vehicle body,

wherein the wheel state detecting device detects a stroke of the suspension.

8. The vehicle according to claim 4, wherein the wheel state detecting device detects a rotational speed of the wheel.

9. The vehicle according to claim 4, wherein the wheel state detecting device detects a ground contact force on the wheel.

10. The vehicle according to claim 4, further comprising a suspension that suspends the wheel on a vehicle body,

wherein the wheel state detecting device detects a stroke of the suspension.
