摘要： PURPOSE:To realize excellent responsiveness and stability of the yaw motion by executing the feed-forward control of the rear wheel steering by the front wheel steering angle and the vehicle speed, and executing the feedback control of the driving force distribution by the detected yaw rate. CONSTITUTION:A microcomputer 57 determines the rear wheel steering quantity based on the detected values of a front wheel steering angle sensor 51 and a vehicle speed sensor 52, and this determination allows the steering control of rear wheels RW1, RW2. At the same time, the driving force distribution is feed-back controlled based on the detected value of a yaw rate sensor 56 so that the difference between the actual yaw rate and the target yaw rate may be eliminated. In a rear wheel steering mechanism 40, a power cylinder 43 improves the responsiveness by direct steering of the rear wheels RW1, RW2. On the other hand in the driving force distribution, a pressure control valve 25 changes the transmitted torque by controlling the pressure to a wet-type multi-branched clutch 23 provided in a sensor differential 14 by means of a driving system control circuit 58, and improves the stability by increasing the effect to the yaw motion.

摘要： PROBLEM TO BE SOLVED: To provide a new detection method that can precisely detect tire air pressure in a vehicle speed range higher than the vehicle speed range in which a detection method conventionally proposed as an indirect detection method can precisely detect tire air pressure. SOLUTION: A vibration level in a specific frequency range of wheel speed signals as time-series data on wheel speed detected by a wheel speed sensor for detecting an angular velocity of a wheel as a wheel speed is detected as an objective vibration level, according to which tire air pressure is estimated. Whether the estimation of tire air pressure is effective or not is determined according to a vibration-characteristic related value related to characteristics of vibration in the specific frequency range of the wheel speed signals.

摘要： PROBLEM TO BE SOLVED: To hold high robust property in the case of controlling a control system having long dead time by using a sliding mode controlling method. SOLUTION: The controlling method filters a deviation between a set point and the practical value of state quantity following the set point or the time integration value of the deviation (step 2), calculates a switching plane σ based on the filtered value (step 3) and outputs a control input value (u) based on the switching plane a (step 4). A filter is set up by comparing the board diagram of a design model based on a normal sliding mode controlling method having no filtering processing with that of a characteristic variation model and executing compensation in a direction for canceling the variation. Since the filtering processing is executed, the control system having dead time can be controlled by the sliding mode controlling method.

A sensor group 40 is provided which controls the engine rotating speed and signals from the sensor group 40 are connected to an automatic speed control computer 30 and an engine control computer 50. Then a clutch controller while inputting the signals from various sensor groups 40 performs control to match with a slip speed target rotational frequency at a speed change point of the automatic gear 10.
