    摘要: A vehicle speed control system is installed to a vehicle equipped with an engine and a continuously variable transmission (CVT). The vehicle control system is comprised of a controller arranged to execute a vehicle speed control, to suspend the vehicle speed control when a throttle opening is increased to be greater than a target throttle opening for the vehicle speed control and to restart the suspended vehicle speed control when the throttle opening becomes smaller than the target throttle opening. Further, the controller is arranged to decrease the throttle opening and to execute a shift down of the CVT when the vehicle speed at the moment of restarting the vehicle speed control is greater than or equal to the target vehicle speed. Therefore, this vehicle speed control system can quickly and smoothly decelerate the vehicle without generating shift shocks when the vehicle speed control is restarted.

    摘要: A vehicle speed control system is adapted to a vehicle equipped with an automatic transmission with a torque converter. The vehicle speed control system detects whether the automatic transmission is put in a lock-up condition, and corrects a command drive torque according to the lock-up condition of the automatic transmission. Particularly, the vehicle speed control system decreases a correction quantity of the command drive torque when the automatic transmission is put in the un-lockup condition. Therefore, the vehicle speed control system can adapt its response characteristic to a controlled system response characteristic which varies according to the lock-up condition of the transmission.

    摘要: In current servo amplification/control apparatus and method for a reversible DC motor applicable to a vehicular four-wheel steering system, a motor current detection circuit and a motor current feedback circuit are eliminated and a motor counter-electromotive force is estimated using a dynamic characteristic of the motor, a positioning currenu, and an angular displacement information of the motor, and the motor power supply voltage directly measured is corrected using the estimated counter- electromotive force. Thus, a positioning response of the motor is derived which is approximately coincident with a design target even when the motor is rotated at a high speed.

    摘要: In a control apparatus for controlling a gear shift ratio of a continuously variable transmission mounted in an automotive vehicle as an automatic power transmission, a gear shift ratio command value is calculated using a control constant corresponding to a dynamic characteristic determined for each instantaneous gear shift ratio of the continuously variable transmission so as to achieve a target gear shift ratio response characteristic. In addition, a disturbance compensator (robust compensator) of a robust type filter is used against a disturbance such as a parameter variation to achieve a gear shift ratio control characteristic that a designer of the control apparatus has desired to achieve in cases where the parameter variation occurs due to a load variation, a change in an environment temperature or deterioration of an oil viscosity in a hydraulic pressure mechanism which creates a pressing force on each of drive and driven pulleys of the continuously variable transmission and where an individual difference in the dynamic characteristic of the continuously variable transmission due to a working and/or assembly accuracy of a power transmission part of the continuously variable transmission occurs.

    摘要: In a steering angle control system including a feed-forward control for producing a desired vehicle motion variable and a feedback control for suppressing disturbances, a controller calculates a corrected steering angle from a detected steering angle and a premeasured characteristic of a steering system. The desired vehicle motion variable is calculated from a vehicle speed and the corrected steering angle. The feedback control is executed according to the difference between the desired and detected vehicle motion variables. Therefore, a driver can control a vehicle with a smooth control response in spite of a non-linear characteristic of the steering system.
