Samenvatting
The effect of four- wheel steering on vehicle handling and stability was investigated. It was found that vehicle stability is improved by steering the rear wheels in the same direction as the front wheels. The steer angle of the rear wheels should increase with increasing vehicle velocity. Transient characteristics of the rear wheel steer angle are important in achieving both good stability and steering response. One way of achieving this is to introduce a suitable time delay in the rear wheel steer angle.
