Problems solved by technology

[0008] However, in the former technology, although the performance can be fully exhibited in terms of maintaining high grip during cornering, it is still insufficient in terms of considering both high grip and low fuel consumption (low rolling resistance) place
In addition, in the above-mentioned prior art, it is limited to ensure high grip when turning, and there is a deficiency when exerting high grip when, for example, sudden acceleration and sudden braking when running straight.
Also, in the latter technology, there are deficiencies in considering both high grip and low fuel consumption

Embodiment Construction

[0067] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a schematic diagram schematically showing a vehicle 1 equipped with a vehicle control device 100 according to the first embodiment of the present invention. in addition, figure 1 Arrow FWD in the arrow indicates the forward direction of the vehicle 1 .

[0068] First, a general configuration of the vehicle 1 will be described. Such as figure 1 As shown, the vehicle 1 mainly includes a vehicle body frame BF, a plurality of (four in this embodiment) wheels 2 supported by the vehicle body frame BF, a wheel driving device 3 that independently rotates and drives each wheel 2, and a driver for each wheel. 2. The camber angle adjusting device 4, which performs steering drive, camber angle adjustment, etc., controls the camber angle of the wheel 2 by the vehicle control device 100, and uses two types of tire treads provided on the wheel 2 (se...

Abstract

A controller for vehicle which can satisfy both high grip performance and low fuel consumption while ensuring excellent safety during running. The controller for vehicle comprises a means for calculating the coefficient of friction between the wheel and the surface of running road, a means for calculating the command value of camber angle of the wheel based on the coefficient of friction thus calculated, and a means for selecting a wheel which operates a camber angle controller based on the operating state of a brake operation member detected by a brake detection means. Based on the command value of camber angle calculated by the camber angle calculation means, a first camber angle alteration means adjusts the camber angle of the wheel selected by the wheel section means. With such an arrangement, the wheel can exhibit a coefficient of friction required for suppressing slip of wheel surely while enhancing fuel saving performance, and acceleration performance, brake performance or turning performance can be enhanced more effectively.

Description

technical field [0001] The invention relates to a vehicle control device for controlling the camber angle of the wheels through the operation of the camber angle adjusting device for a vehicle having a wheel and a camber angle adjusting device for adjusting the camber angle of the wheel, in particular to A control device for a vehicle capable of achieving both high grip and low fuel consumption. Background technique [0002] At present, people are trying to give full play to the ability of the tire and improve the cornering performance by increasing the camber angle (the angle between the center of the tire and the ground) of the wheel in the negative direction. If the camber angle is set to, for example, 0°, the tire tread will be in contact with the ground in the entire width direction when driving straight, and the centrifugal force will make the tire tread located on the inner side of the vehicle trajectory float from the ground when turning, so that sufficient turning ...
