摘要： An apparatus that detects a reference position of a throttle valve. The throttle valve is forced in either a valve opening direction or a valve closing directions by an urging member. A DC motor, which is connected to the throttle valve, drives the throttle valve against the force created by the urging member within a rotatable angle that is restricted by a stopper. A throttle valve opening sensor detects an opening angle of the throttle valve. A lock current detecting circuit detects a lock current created by the DC motor when the DC motor is brought into contact with the stopper. A throttle valve reference position renewing circuit updates the reference position, which is memorized in a throttle valve reference position memory, on the basis of an opening angle of the throttle valve, which is detected by the throttle valve opening sensor, when the lock current detecting circuit detects the lock current.

摘要： A vehicle slip control system for controlling a wheel slip based on a friction coefficient of a road surface measures an engine torque T.sub.E by applying an intake pipe negative pressure Pm and a number of engine revolutions Ne to an engine model. A drive torque T is measured by applying the engine torque T.sub.E to an A/T model, and a driving wheel acceleration d.omega. is obtained by finding a difference of a detected driving wheel speed .omega.. By filtering this driving wheel acceleration d.omega., a post-filter driving wheel acceleration d.omega..sub.0 is calculated. A squat force Ws is calculated from the drive-torque T and the post-filter driving wheel acceleration d.omega., and a friction coefficient .mu. of the road surface is estimated from the squat force Ws. The estimated friction coefficient .mu. is used to control a wheel slip.

The throttle valve control apparatus includes a lever connected to the throttle valve for movement in an opening direction and a closing direction together with the throttle valve. An opening degree limiting member is located in a side of the lever which corresponds to the opening direction. A spring urges the opening degree limiting member in a direction of closing the throttle valve. An accelerator interlocking and driving device serves to move the opening degree limiting member in accordance with a degree of operation of an accelerator member. A throttle actuator functions to adjust a degree of opening of the throttle valve. A vehicle speed sensor functions to detect a running speed of the vehicle. A guard actuator serves to adjust a position of the opening degree limiting member. An auto cruise control device serves to control the throttle actuator and to feedback-control the vehicle speed detected by the vehicle speed sensor at a target vehicle speed. A guard control means serves to control the guard actuator and to adjust the position of the opening degree limiting member at a position slightly separated from a position of the lever in the opening direction during control by the auto cruise control device. A changing device serves to change control of the position of the opening degree limiting member by the guard control device and control of the position of the opening degree limiting member by the accelerator interlocking and driving device with each other.

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.
