    摘要： A hybrid vehicle has an internal combustion engine, an electric motor, a transmission unit and driving wheels. The transmission unit includes a planetary gear unit and a one-way clutch, so that each output rotary speed of the internal combustion engine and the electric motor is changed. The planetary gear unit includes three elements: a ring gear, a sun gear and a carrier having at least one pinion. When the vehicle is in an under-drive cruising state, the first element of the planetary gear unit, which does not rotate, is connected to the output shaft of the internal combustion engine, the second element of the planetary gear unit, which rotates at a relatively high, speed, is connected to the output shaft of the electric motor, and the third element of the planetary gear unit, which rotates at relatively lower speed, is connected to the output shaft of the transmission unit. The one-way clutch is provided between the output shaft of the internal combustion engine and a case housing the transmission unit to allow the output shaft of the internal combustion engine to rotate in one direction only.

    摘要： A driving force controller for an electric motor vehicle which suppresses changes in behavior of a vehicle when a right or left driving wheel experiences trouble and detects vehicle conditions to independently control the driving force of each wheel so as not to deviate from a predetermined range. The driving force controller computes a driving force for each wheel in accordance to a demand value for driving force and a detected vehicle traveling condition to drive each wheel independently by electric motors. Motor drivers control the motors so that each motor generates power corresponding to the value of driving force computed therefor. A driving demand detector detects the value of driving force demanded for the vehicle and a vehicle condition detector detects a traveling condition of the vehicle. Wheel driving condition detectors detect conditions at the wheels. A computer computes the values of driving force to be provided at each wheel in accordance with the value of driving force demanded and the detected vehicle traveling conditions and corrects the values computed for individual wheel driving forces when a vehicle traveling condition or a wheel driving condition exceeds a predetermined range.

    摘要： A system for controlling the hydraulic pressure of a hydraulic control circuit of an automatic, variable speed transmission during a shift operation is provided. The hydraulic control circuit includes a plurality of hydraulic pressure control valves, a plurality of flow path switching means and a plurality of solenoid valves for controlling the engagement and disengagement of clutches and brakes in the transmission. The energization of the solenoid valves disposed in the hydraulic control circuit is controlled by an electronic system, which comprises a large scale integrated semiconductor logic unit, a semiconductor read-only memory, a semiconductor read-write memory and as required, input/output ports. The semiconductor read-only memory stores, inter alia, hydraulic pressure control program data which become operative during a selected one of the shift modes, each of which comprises a combination of the current speed stage and the speed stage to be established, and which controls the hydraulic pressure of the hydraulic control circuit by a repeated deenergization and energization of the solenoid valve for a given time interval during the shift operation.A signal indicative of a shift lever position is applied to the electronic system from a shift lever detecting means. Also a signal indicative of the current vehicle speed is applied thereto from a vehicle speed signal generating means. Finally, a signal indicative of a throttle opening is applied to the system from a throttle opening detecting means. In response to these signals and based on the constants data and the program data which are stored in the read-only memory, the electronic system determines a speed stage to be established. The hydraulic pressure in the hydraulic control circuit is controlled, simultaneously with a switching of the speed stage, on the basis of the hydraulic pressure controlling program data, thus reducing any rapid fluctuation of the vehicle speed or impulses during a shift operation.
