Problems solved by technology

[0004] However, in the technology disclosed in the above-mentioned Patent Document 1, when the vehicle travels on an expressway or an arterial road for a long time at a predetermined speed or more, since negative camber is continuously applied to the wheels during this period, there is a The life of the tire is shortened due to uneven wear of the tire, and the running stability of the vehicle is reduced due to the uneven contact surface of the tire

Abstract

The disclosed control apparatus for vehicle use can suppress the uneven wear of a tire, increasing the lifespan of the tire, and can secure running stability of the vehicle. When the ground contact load of a wheel (2) is determined to be at least a predetermined ground contact load, the camber angle of the wheel (2) is adjusted to a second camber angle (a camber angle having a smaller absolute value than that of a first camber angle), and since the imparting of negative camber to the wheel (2) is terminated, uneven wear of the tire is suppressed. As a result, the lifespan of the tire can be increased. Also, through suppressing uneven wear of the tire, the ground contact surface of the tire is prevented from becoming uneven, and running stability of the vehicle (1) can be secured.

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 particularly relates to a vehicle control device capable of suppressing uneven wear of tires, increasing the life of the tires and ensuring the running stability of the vehicle Vehicle control device. Background technique [0002] Conventionally, there is known a technique for ensuring the running stability of a vehicle by adjusting the camber angle of a wheel according to the running state of the vehicle. Regarding such a technique, for example, Patent Document 1 discloses a technique for improving the limit performance of the vehicle during spinning running by detecting the vehicle speed and applying negative camber to the wheels when the vehicle speed exceeds a predetermined speed. [0003] Patent Document 1: Japanese Patent Laid-Open No. 60-193781 [0004] However, in the technolo...
