Vehicle control device
First Claim
1. A vehicle control device which activates a camber angle adjustment device which adjusts a camber angle of a wheel to control the camber angle of the wheel, comprising:
- activation control means for controlling an activation state of the camber angle adjustment device,wherein the wheel includes a first tread and a second tread aligned in a width direction of the wheel with respect to the first tread and arranged on an inside or an outside of the vehicle,wherein the first tread and the second tread are configured to have characteristics different from each other such that the first tread is configured to have a characteristic of a higher grip force compared to the second tread and the second tread is configured to have a characteristic of a smaller rolling resistance compared to the first tread,wherein the activation control means includes;
vicinity information acquisition means for acquiring vicinity information on a vicinity of the vehicle;
characteristic determination means for determining a characteristic necessary for the wheel, based on the vicinity information acquired by the vicinity information acquisition means, andcamber angle change means for activating the camber angle adjustment device to change the camber angle of the wheel such that the wheel exhibits the characteristic determined by the characteristic determination means; and
wherein the vicinity information acquisition means includes;
current position detection means for detecting a current position of the vehicle;
map data storage means for storing map data; and
situation acquisition means for acquiring a situation of a route that the vehicle is to follow as the vicinity information based on the map data stored in the map data storage means and the current position of the vehicle detected by the current position detection means.

Abstract
A vehicle control device which can at least provide compatibility between a high grip performance and fuel efficiency or compatibility between quietness and fuel efficiency is provided. When a camber angle of a wheel 2 is adjusted to a negative camber, ground contact in a first tread 21 is increased and ground contact in a second tread 22 is decreased. Accordingly, the high grip performance or the quietness is provided. On the other hand, when the camber angle of the wheel 2 is adjusted to a positive camber, the ground contact in the first tread 21 is decreased and the ground contact in the second tread 22 is increased. Accordingly, a rolling resistance becomes low, and fuel saving is achieved. In this manner, by adjusting the camber angle of the wheel 2, the compatibility can be provided between conflicting performances of the high grip performance or the quietness and the fuel saving.
