摘要： In a traction control device in which an initial control torque of an engine is determined in accordance with an acceleration of the vehicle, when an excessive slipping of driven wheels is detected, a time taken for proceeding of the excessive slipping of the driven wheels from a large slip state to a small slip state is counted by a timer. If such time is smaller than a reference time and a gear ratio of the vehicle is of a first gear shift to provide a low vehicle speed, it is decided that the vehicle is traveling on an upward sloping road, and a lower limit value for defining the initial control torque of the engine determined in an initial control torque calculating means is corrected into an increased value in an initial torque correcting means. This prevents the initial control torque of the engine from being excessively reduced at the start of a traction control. By this construction, it is possible to prevent an initial control torque from being excessively reduced due to a misjudgment of a friction coefficient of a surface of an upward or downward sloping road to insure an acceleratability of a vehicle.

摘要： A method for determining the fully-closed state of a subsidiary throttle valve. If a stable state judging circuit judges that there is no outside influence exerted on the operational state of the engine (a state in which the vehicle is stopped and the engine is in an idling state) even if the subsidiary throttle valve is fully closed, a valve closing circuit closes the subsidiary throttle valve and a fully-closed state determination is carried out. If the opening degree of the subsidiary throttle valve or the engine revolution number is largely varied during the determination process of the fully-closed state determination circuit, a valve-closing inhibiting circuit inhibits the closing of the subsidiary throttle valve to discontinue the determination. Even if all of the conditions for determination are satisfied again, the closing of the subsidiary throttle valve and the restarting of determination by the fully-closed state determination circuit are inhibited until the comparator circuit judges that the vehicle starts traveling and vehicle speed exceeds a reference value.

摘要： The rotational speed difference between rotational speeds of front and rear road wheels of a motor vehicle is weighted by a first ratio, and the difference between the rotational speed difference between rotational speeds of front left and right road wheels and an average signal of reference steering angle or between the rotational speed difference between rotational speeds of rear left and right road wheels and the average signal of reference steering angle is weighted by a second ratio.

摘要： A reduction in pressure in tires fitted to follower wheels and driven wheels is precisely determined irrespective of slipping states of the driven wheels. A driven wheel slip rate calculating means M1 calculates driven wheel slip rates .lambda.L and .lambda.R. A driven wheel torque calculating means M2 calculates a driven wheel torque TQDW. A driven wheel slip rate estimating means M4 estimates a characteristic of variation in driven wheel slip rates .lambda.L and .lambda.R relative to the variation in driven wheel torque TQDW using a least squares method. A rotation-number ratio calculating means M5 calculates ratios CVWL and CVWR of the numbers of rotations of the follower wheels to the numbers of rotations of the driven wheels in a state in which the driven wheel torque in a graph of the variation characteristic is equal to zero. A tire pressure-reduction determining means M6 then determines a reduction in pressure from a difference in diameter between the follower wheels and the driven wheels by comparing the rotation-number ratios CVWL and CVWR with a reference value.

摘要： In a traction control system, an initial engine torque for a traction control is selected from the following engine torques: an engine torque calculated from a throttle opening degree and an engine revolution-number; a required engine torque calculated from a total acceleration and a vehicle speed; and an engine torque corresponding to a road surface of an extremely low friction coefficient, depending upon a slipping state determined by comparing a driven wheel speed with slip reference values. When the driven wheel speed repeatedly exceeds the slip reference value, it is determined that a hunting has been generated, and the engine torque corresponding to the road surface of the extremely low friction coefficient is selected, and the engine torque is largely reduced. Thus, when the friction coefficient of the road surface is low, the driven wheel speed is prevented from hunting.

摘要： A subtractor calculates an actual wheel speed difference between rotational speeds of left and right wheels on a motor vehicle, and a steering angle converter calculates an actual steering angle from the actual wheel speed difference. The difference between the actual steering angle and an adequate steering angle which is produced based on a lateral acceleration is compared with a predetermined reference range. If the difference between the actual and adequate steering angles exceeds the predetermined reference range, then the pneumatic pressure of a tire on one of the left and right wheels is determined as being lowered. In the steering angle converter, a weight value is established according to a running condition of the motor vehicle, and the calculated actual steering angle or comparative sensitivity is varied according to the weight value. Since the comparative sensitivity is varied according to the running condition, a reduction in the pneumatic pressure of the tire can be detected even under running conditions which lead to large errors.

摘要： A traction control system for a vehicle includes a calculator for calculating a speed of a driven wheel of the vehicle, a calculator for calculating a vehicle speed and a calculator for calculating a slip rate of the driven wheel on the basis of the driven wheel speed and the vehicle speed, such that the feed-back control of a throttle valve is carried out to reduce the output torque from an engine to inhibit the excessive slipping of the driven wheel, when the slip rate exceeds a predetermined threshold value. The system further includes a calculator for calculating a total grip force of the vehicle, a calculator for calculating an initial engine required torque at the start of the feed-back control of the throttle valve on the basis of the total grip force, and a calculator for calculating an initial throttle opening degree of the throttle valve on the basis of the initial engine required torque. Thus, the excessive slipping of the driven wheels can be reduced without an abrupt change exerted to the behavior of the vehicle by setting an appropriate initial throttle opening degree.
