    摘要: A sensor voltage reading circuit for reading an analog sensor value is provided which can remove electromagnetic wave noise inputted to an input terminal of an A/D conversion circuit. The sensor voltage reading circuit includes a first voltage division circuit and a second voltage division circuit for dividing the output voltage of a potentiometer. An A/D conversion circuit has input terminals connected to the output terminals of the voltage division circuits and a processing unit for reading digital voltages obtained by conversion of the A/D conversion circuit. The processing unit removes from the converted voltages a noise voltage caused by radio waves which mix into the input terminals of the A/D conversion circuit. Accordingly, the reading accuracy of the output voltage of the sensor can be enhanced. In a further embodiment, the sensor voltage reading circuit can suppress power dissipation by the analog sensor to achieve miniaturization of the power source circuit.

    摘要: A regenerative braking system in a motor vehicle determines a state of deceleration on the basis of the number of revolutions of a motor and an accelerator signal and performs a regenerative braking according to the state of deceleration. The regenerative braking system includes a revolution sensor for detecting;the number of revolutions of a rotor of a vehicle driving motor and an accelerator opening sensor in a RAM stores discrimination data for discriminating between a regenerative braking mode and a drive mode on the basis of the number of revolutions of the rotor and the accelerator opening and also stores on-off duty ratio data of FETs in the regenerative braking mode and that in the drive mode. A CPU retrieves on-off duty ratio data corresponding to the number of revolutions of the rotor and the accelerator opening in the regenerative braking mode when the regenerative braking mode is determined on the basis of the rotor revolutions and the accelerator opening, and controls the FETs at an on-off duty ratio corresponding to the retrieved on-off duty ratio data. The power unit for the motor vehicle is an electric motor mounted in unit cases using at least a portion of the unit cases as a motor case. In the power unit of such construction, a heat sink is attached to the motor case. Switching elements are provided for controlling an electric current to be supplied to the electric motor. The switching elements are mounted to the heat sink.

    摘要: An engine control device is provided for reducing the retrieving time of control data from sensors at high and low engine speeds. Control parameters from the sensors are converted into memory access parameters to a control map to recover the desired injection amount. The fuel injection quantity is calculated by retrieving fuel injection amounts using the memory access parameters as addresses and performing a four-point interpolation of the memory parameters. A previously retrieved value is used as a reference value to aid the determination of an updated memory access parameter so that the retrieving time can be reduced for high and low engine speeds.
