    Abstract: A control system for controlling a lock-up clutch of a torque converter employed in an automatic transmission of a vehicle, the lock-up clutch being controllable by a pressure differential between apply and release pressures comprises a detector for detecting a demand of change (decrease/increase) in the pressure differential, a pressure-differential setting circuit for setting a target pressure differential in response to the demand of change in the pressure differential, and a pressure-differential filter having a desired dynamic characteristic and being responsive to the target pressure differential for outputting a filtered pressure-differential command value via a filtering process based on the desired dynamic characteristic. A pressure-differential regulation circuit is connected to the pressure-differential filter for receiving the filtered pressure-differential command value as an input information data to generate an output indicative of a duty ratio to be output to a lock-up solenoid valve and for regulating the pressure differential in accordance with the duty ratio.

    Abstract: A speed change ratio of a continuously variable transmission for converting the rotation of the output shaft of an engine in a stepless manner and transmitting it to a drive shaft of a vehicle is controlled to a target speed change ratio. A target vehicle speed at a predetermined future time is estimated based on a real vehicle speed, and the target speed change ratio is calculated based on the estimated vehicle speed. By controlling a real speed change ratio to this target speed change ratio, the response of the transmission is enhanced. Preferably, a feedback vehicle speed is calculated by processing the estimated vehicle speed with a predetermined lag element. By integrating a difference between the real vehicle speed and feedback speed so as to estimate the vehicle speed at the predetermined future time, hunting of the speed change ratio in the speed change ratio control is suppressed.

    Abstract: A sensor is provided for detecting traveling speed of a vehicle, and a first deviation between the traveling speed and an estimated vehicle speed calculated beforehand is calculated. Based on the first deviation and a predetermined function, a feedback compensation output is calculated, and a second deviation between a value obtained by performing on the feedback compensation output and the aforesaid estimate vehicle speed is output as an estimated acceleration. Delay processing is performed on the estimated acceleration, and an estimated vehicle speed is updated. Noise mixed with the acceleration estimation process is eliminated, and the acceleration is thereby estimated with high precision.

    Abstract: A rear wheel steering angle control system for a 4WS vehicle is provided. This system includes a first circuit for deriving a locus defined by a specific point provided on the front end of the vehicle, a second circuit for deriving a locus defined by a specific point provided on the rear end of the vehicle, a third circuit for providing a target steering angle for the rear wheels so that a rear corner does not overhang outwardly during turning, and a controller for controlling an actual angle for steering the rear wheels. The third circuit determines the target steering angle so as to restrict the magnitude of offset of the rear specific point from the locus of the front specific point. The controller steers the rear wheels by the target steering angle to restrict the magnitude of overhang of the rear end of the vehicle and enables the vehicle to turn within the minimum possible turning circle.

    Abstract: An apparatus for controlling a motion of a vehicle supported on steered and non-steered road wheels. A target vehicle motion value is calculated based on the steering angle and vehicle speed to provide a predetermined response characteristic related to a vehicle plane behavior. A target steering angle value for the non-steered road wheel to realize the vehicle plane behavior is calculated according to the target vehicle motion value. The non-steered road wheels are steered according to the calculated target steering angle value. The damping characteristic of the response characteristic is decreased as the vehicle speed increases.

    Abstract: A rotation pulse signal is generated according to a vehicle speed sensor. An acceleration detector calculates a threshold value of a pulse cycle on a subsequent occasion based on a latest pulse cycle and an acceleration which it is desired to detect. By comparing the pulse period on the subsequent occasion with the threshold value, it is determined whether or not a specified acceleration has been reached. After this determination, a threshold value for the subsequent occasion is calculated. By detecting whether the specified acceleration has been reached without calculating an acceleration value, the time from output of the pulse signal to detection of the specified acceleration is shortened.
