  • Patent number: 6874471
    Abstract: When the position of a throttle valve approaches a target value, an integration calculation of position control is stopped. When a deviation from the target value increases, the integration calculation is restarted. If an integration value includes no frictional amount, a motor output in which a motor and a spring are matched is set synchronously with a change in target value.

  • Patent number: 5975739
    Abstract: A control processor has an output pattern generating circuit operating in cooperation with a free running timer, and a virtual OCR program for virtually realizing a large number of timer outputs by use of the output pattern generating circuit. Because more timer outputs than the actually incorporated timers are handled, the function of timer outputs is implemented with a higher degree of freedom and in a wider range of applications. For its enhanced function and availability, the control processor costs less.

  • Patent number: 5968100
    Abstract: A vehicle control system provided with a plurality of sensors for detecting the condition of the vehicle, a vehicle control unit including a multiplexer, a programmable input signal matching module and a processor, and actuators for operating each part of the vehicle. The multiplexer and matching module are selected and switched in accordance with a sensor signal to be inputted. A plurality of sensor signals can be inputted through the switched multiplexer and matching module to the processor. Furthermore, the processor determines controls of vehicle operation on the basis of the inputted sensor signals and controls actuators in accordance with the determined controls.
