PURPOSE:To smoothly and rapidly conduct acceleration and deceleration and enable the smooth drive according to a driver's will by inferring the acceleration and deceleration required by the driver from accelerator opening by fuzzy inference, and constituting two-freedom control system. CONSTITUTION:An automatic drive controller 11 compares the acceleration required by a driver calculated from the signal of an accelerator opening sensor 21 with the actual acceleration by the signal of a G sensor 22. By the outputs of the automatic drive controller conducting fuzzy theory and a stability strengthening controller using two freedom control to improve stability, a throttle is controlled. When the accelerator operating force is large, for example, the throttle opening and the damping force of a suspension are increased, and when the accelerator operating force is middle, and the accelerator operating speed is high, the throttle opening is increased. The driving property can be improved by use of this fuzzy rule, and the automobile can be accelerated according to the requirement of the driver over the whole driving area. |
