摘要： In a traction control system for a vehicle which controls the traction of the driven wheels according to the slip ratio of the driven wheels obtained as a relationship between the vehicle speed and the speed of the driven wheels, the vehicle speed is obtained from the speed of the non-driven wheels. Normally, the average value of the speeds of the non-driven wheels is used as the basis for computing the vehicle speed, but when one of the non-driven wheels is likely to be lifted from the road surface due to the turning maneuver of the vehicle, the speed of one of the non-driven wheels which is higher than that of the other non-driven wheel and is therefore likely to be in contact with the road surface is used for fining the vehicle speed. Thus, the vehicle speed is simply obtained from the speed of the non-driven wheels, but the traction control can be reliably carried out according to a correctly obtained vehicle speed.

摘要： A steering angle detecting system for a vehicle includes a sensor responsive to rotation of a steering wheel for generating angular pulses corresponding in number to the steering angle of the steering wheel. Another sensor generates a reference pulse at a predetermined angle of the steering wheel. The angular pulses are counted by a counter. The steering angle detecting system is determined to be abnormal if the counted value of the counter is not within a predetermined value range when the reference pulse is generated. Further, the rate of change of the counted value by the counter is detected, and the steering angle detecting system is determined to be abnormal if the detected rate of change of the counted value is greater than a predetermined value. Further, the steering angle detecting system is determined to be abnormal if the detected rate of change of the counted value has continued to be smaller than a predetermined value for a predetermined time period or longer.

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 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： 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.
