    摘要: To prevent an alteration of the target slip amount of a lock-up clutch slip control due to changes over time of a automatic transmission, and moreover to improve fuel consumption without reducing drivability, a lock-up clutch is mounted inside a torque converter. Inside the lock-up clutch, operational oil is supplied while switching between a release state and an engaged state of the clutch according to the switching function of a clutch control solenoid. Furthermore, the arbitrary slip amount (slip rate) is regulated using these two components. As a result of these controls, there is mapping of the target slip amount in the operating ranges having as parameters the throttle aperture change rate and turbine rotational speed of a throttle valve included on the intake pipe of the internal combustion engine and the turbine rotational speed of the torque converter. If the throttle aperture change rate goes above a predetermined value, the target slip amounts of the operating ranges are updated based on the target slip amount of the operating range at that time.

    摘要: A throttle control device for a vehicle engine enables adjustment of pedal feeling of an accelerator pedal in accordance with a state of operation of the engine. A throttle valve provided in an intake pipe of an engine is actuated to vary its opening by a stepping motor. The accelerator pedal is provided with an accelerator opening sensor 10 which detects an amount of step down or operation of the accelerator pedal. The engine is provided with a water temperature sensor capable of detecting a temperature of cooling water circulated through the engine. A shift lever device is provided with a shift position sensor capable of sensing a range to which the shift lever has been operated. A CPU sets an amount of play of the accelerator pedal, i.e., a width of an insensitive zone, in accordance with the temperature of the cooling water detected by the water temperature sensor and the shift position detected by the shift position sensor. The CPU controls the stepping motor to attain a throttle opening corresponding to the accelerator operation amount after correction of the latter in accordance with the set amount of play of accelerator pedal operation.

    摘要: A throttle control apparatus includes an electrical drive unit for electrically driving a throttle of an internal combustion engine and a mechanical drive unit for driving the throttle through the operation of an accelerator by a driver. In the case where an abnormality is generated in the electrical drive unit, the driving of the throttle by the electrical drive unit is interrupted and the throttle is thereinstead driven by the mechanical drive unit. The mechanical drive unit is provided with a throttle opening angle control member. The throttle control apparatus further includes a torque control unit for suppressing an increase in output torque of the internal combustion engine in the case where a throttle opening angle is increased in the direction of an opening angle set by the throttle opening angle control member when the driving of the throttle by the electrical drive unit is interrupted.

    摘要: A traction control system controls the engine torque so as to prevent wheel slip during acceleration. The system has an electric control unit ECU which detects the state of wheel slip on the basis of the deviation of the drive wheel speed from a target drive wheel speed computed in accordance with signals from various sensors such as drive wheel speed sensors, trailing wheel speed sensors, shift position sensor for sensing the shift position in an electronic control transmission ECT, engine speed sensor and accelerator sensor for sensing the amount of operation of accelerator. The ECU computes, in accordance with the state of the slip, a limit drive torque which does not allow surplus wheel slip during acceleration. The ECU also updates the limit drive torque depending on whether the surplus slip takes place on drive wheels, and detects also the amount of operation of the accelerator so as to inhibit updating of the limit drive torque when the detected amount of operation of accelerator is below a value corresponding to a limit throttle opening, whereby the engine is controlled such that the drive torque applied to the drive wheels is maintained below the limit drive torque.
