    摘要: A slip control system for a motor vehicle controls slippage of driving wheels and includes a sensor for detecting a slip ratio of each driving wheel, a device for decreasing slip of each driving wheel by controlling a driving force transmitted to the driving wheel so that the slip ratio of the driving wheel is at least equal to a predetermined desired slip ratio when the slip ratio of the driving wheel is equal to the desired slip ratio, a sensor for detecting a yawing rate of the vehicle, and a sensor for detecting a steering amount of the vehicle. The slip decreasing device includes a correcting device for decreasing the desired slip ratio when a steering condition is detected based on amounts detected by both the yawing rate detecting sensor and the steering amount detecting sensor.

    摘要: A traction control device operates to determine the speed of each of the left and right drive wheels of a vehicle, determine the speed of each of the left and right passive wheels of the vehicle, calculate the actual slip rate of the drive wheels of the vehicle directly based on the measurements of the speeds for the drive and passive wheels, establish a target slip rate and control the driving condition of the vehicle by making the actual slip rate equal the target slip rate. The actual slip rate is matched to the target slip rate by controlling engine output and braking power. The step of controlling the driving condition of the vehicle by controlling the engine output and the braking power is carried out according to the time differential of the difference between the actual slip rate and the target slip rate at least until the actual slip rate matches the target slip rate for the first time. After the actual slip rate has matched the target slip rate at least once, the step of controlling is carried out according to the proportion of the difference between the actual and the target slip rates.

    摘要: When a wheel slip value of the driven wheel relative to a surface of road becomes excessive during acceleration, torque to be applied to the driven wheels is controlled by the traction control so as to make the actual wheel slip value of the driven wheel become a predetermined target value. There is counted the duration of time during which the actual wheel slip value of the driven wheel becomes smaller than a predetermined threshold value set as a value smaller than the target value, and a control value for the traction control is corrected in accordance with the duration of time counted. This correction is implemented so as to increase the torque to be applied to the driven wheels larger as the duration of time counted becomes longer. The control value to be corrected includes the target value itself or a road surface friction coefficient .mu. as a parameter for setting the target value.

    摘要: The braking force to the driven wheels is subjected to feedback control so as to allow the actual slip value of the driven wheels to agree with a predetermined target value for controlling the brake. The control amount for the feedback control is determined by differentiation control. The feedback control amount contains a first control amount corresponding to a predetermined basic travelling state and a second control amount corresponding to a particular travelling state. In ordinary travelling state, the braking force is controlled by the first control amount, and the braking force is controlled by the second control amount when the automotive vehicle is travelling in such a particular state. When the the vehicle is travelling on a bad road, the second control amount is set so as to loosen the braking force, as compared with the first control amount. Alternatively, when the vehicle is cornering, the second control amount is set as to tighten the braking force as compared with the first control amount.

    摘要: An assumed vehicle body speed is determined on the basis of the wheel speed detected by a wheel speed sensor for each wheel and a slip value indicating the tendency of locking the wheel is determined for a predetermined wheel speed on the basis of the assumed vehicle body speed and a wheel speed of the predetermined wheel. The braking force is controlled on the basis of the slip value. When no braking force is controlled and when at least one of the wheel speeds for all the wheels detected by the wheel speed sensors is larger than the assumed vehicle body speed previously determined, a new assumed vehicle body speed which follows is inhibited from being renewed to a larger value and the new assumed vehicle body speed is set as a value equal to the previous assumed vehicle body speed.

    摘要: A clutch control system for automobiles comprising a clutch actuating member for actuating a clutch positioned between an engine output shaft and a transmission input shaft, and a suction pressure operated actuator for moving a clutch actuating member to a clutch releasing position. A detecting circuit is provided for detecting a negative differential coefficient of the engine speed and generating a corresponding output. A vacuum control valve is provided in a line to the clutch actuator to operate the clutch release. The line is also provided with a holding valve which is closed when the detecting circuit detects the negative differential coefficient of the engine speed to thereby stop the clutch engaging movement of the actuator momentarily so as to prevent the engine speed from falling off.
