Abstract: The present invention discloses an active suspension vehicle and a control method controlling the same. Each wheel of the vehicle is equipped with a telescopically adjustable active actuator. The control method begins by constructing a load and deformation joint control matrix of the vehicle and measuring the current vehicle parameters; then determining vertical displacement excitation of wheels at a next moment, and pre-calculating passive responses of vehicle height, attitude, and wheel loads at the said next moment; determining the vehicle height, attitude, and feasible wheel load expectations at the said next moment, and inverse-calculating adjustment strokes of the suspension; finally, performing active suspension adjustment to chase the vehicle height, attitude, and feasible wheel load expectations in real-time.

Abstract: A method for scribing a driving trajectory in the test on steering efforts of an automobile, characterized in that, the key points of the driving trajectory can be determined merely by using a tape measure according to the minimum turning radius of the front outer wheel of the automobile, in which the key points are determined by forming a triangle by making use of the flexibility of the tape measure through the distance from the key point to the centre point, the distance from the key point to the vertex and the distance from the centre point to the vertex. The method is simple, the instruments and devices used are very common, the stability of the instruments and devices is high, and the accuracy of key point determining is also relatively high.
