Problems solved by technology

[0004] However, as shown in the technique disclosed in Patent Document 1, in a structure in which the variable-length upper link is operated based on the yaw rate actually occurring in the vehicle, there is a problem that during snaking running in which the yaw rate is constantly changing, The variable-length upper link moves whenever the yaw rate changes, resulting in frequent switching of the camber angle

Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described 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. also, figure 1 Arrows U-D in the arrows indicate the up-down direction of the vehicle 1 , L-R indicate the left-right direction, and F-B indicate the front-rear direction.

[0034] First, a schematic configuration of the vehicle 1 will be described. Such as figure 1 As shown, the vehicle 1 is configured to mainly include: a body frame BF, a plurality of (four wheels in this embodiment) wheels 2 supporting the body frame BF, and a part of the plurality of wheels 2 (in this embodiment). A wheel driving device 3 for rotationally driving the left and right front wheels 2FL, 2FR), a plurality of suspension devices 4 for connecting each wheel 2 to the body frame BF, and a part of the plurality of...

Abstract

Provided is a vehicle control device which can prevent frequent switching of camber angle at the time of slalom driving. In a state where the camber angle of a wheel (2) is adjusted to a first camber angle, the camber angle of the wheel (2) is maintained at the first camber angle until a determination is made that the yaw rate is lower than a threshold (K) and the variation of yaw rate is smaller than a threshold (L), and thereby the camber angle can be maintained at the first camber angle even if the yaw rate does not reach the threshold (L) until the variation of yaw rate drops below the threshold (K). Consequently, a camber angle regulator (44) is not operated every time when the yaw rate drops below the threshold (L) even during slalom driving in which the yaw rate changes constantly, and thereby frequent switching of camber angle can be prevented.

Description

technical field [0001] The present invention relates to a vehicle control device used in a vehicle provided with a camber angle adjusting device for adjusting the camber angle of a wheel, and more particularly to a vehicle control device capable of preventing frequent switching of camber angles during meandering running. Background technique [0002] Conventionally, there is known a technique of operating a camber angle adjusting device to adjust the camber angle of a wheel. Regarding this technique, for example, Patent Document 1 discloses a technique in which a yaw rate sensor is used to detect the yaw rate actually generated by the vehicle, and based on the yaw rate detected by the yaw rate sensor, the variable-length uplink The lever (camber adjustment device) operates to adjust the camber of the wheel. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 5-32113 [0004] However, as shown in the technique disclosed in Patent Document 1, in a structure...
