Abstract
An integrated controller for a vehicle comprises a contact preventive device for detecting a distance between a vehicle and an obstacle and a relative speed, and deciding whether the vehicle may come in contact with the obstacle based on the results of detection so as to perform automatic braking or automatic steering, and a characteristic changing device for causing the suspension or steering characteristic of the vehicle to be changed. The control part of the characteristic changing device changes the suspension or steering characteristic based on information from the control part of the contact preventive device when operating the contact preventive device. In case the characteristic changing device is an active suspension device, the control part changes the suspension characteristic so as to increase a control gain when performing automatic braking and to inhibit the vehicle from being rolled when performing automatic steering. Consequently, it is possible to early change the suspension characteristic when operating the contact preventive device. Thus, the running stability of the vehicle can be enhanced.
