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.

摘要： A control apparatus for use in an internal combustion engine system of a motor vehicle equipped with an automatic transmission having therein a lock-up mechanism. There is included a vehicle resonance reducing section for controlling an opening degree of a throttle valve when the motor vehicle is in an acceleration state so as to reduce a vehicle resonance accompanying an operation of the engine. The vehicle resonance reducing section estimates a torque to be required for the engine on the basis of an accel-operating amount due to the vehicle drive and the engine operating state and corrects the estimated torque by using operation variables of the motor vehicle so as to calculate a target throttle opening degree. Also included in the control apparatus is a lock-up control section for compulsorily locking up the automatic transmission when the vehicle resonance reducing section is in operation. That is, the lock-up control is executed when controlling the opening degree of the throttle valve so as to reduce the vehicle resonance. With this arrangement, it is possible to improve the driveability of the motor vehicle by reducing the vehicle resonance concurrently with enlarging the lock-up region to improve the fuel consumption.

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.

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 throttle valve control apparatus for internal combustion engine stabilizes the engine speed in idle operation by always correcting the full closing reference position in ISC using a single throttle valve. Signals of a neutral position signal, air conditioner signal, electrical load signal, accelerator position signal, engine speed, and water temperature are inputted to a CPU in an electronic control unit via an input circuit. The CPU calculates such a throttle opening as to make the actual speed of the internal combustion engine in idle operation equal to a target speed in idle operation stored beforehand, compares the throttle opening with preset upper limit value and lower limit value of the throttle opening in idle operation, and corrects the full closing reference position of the throttle opening on the basis of the result of comparison. As a result, the full closing reference position in the throttle opening of the throttle valve is always corrected.

摘要： During engine warm-up, a flow regulating unit in a cooling system operates in a fuel efficiency priority mode. In this mode, a head-side cooling water flow rate (Qhd) is regulated to be equal to or smaller than a first upper limit; a block-side cooling water flow rate (Qbk) is regulated to be equal to or smaller than a second upper limit; and cooling water flowing out of a block-side passage and a head-side passage flows mainly into a bypass passage. When a heating request to heat blown air is made during engine warm-up, the regulating unit operates in a heating priority mode. In this mode, Qhd is regulated to be equal to or smaller than a third upper limit; Qbk is regulated to be equal to or smaller than a fourth upper limit; and at least cooling water flowing out of the head-side passage flows into a heat exchanger.
