    摘要： The vehicle slip control apparatus is designed so as to enable the slip control to be done by causing the output torque of the engine to be reduced and operating the brake when an amount of a slip or spinning of the driven wheels is large. A control ratio of the slip control by the brake to the slip control by the engine is altered to an optimum value in accordance with requirements for the driving of the vehicle.

    摘要： A slip control system for a vehicle having rear right and left drive wheels includes a traction control for controlling a slip rate of a wheel by controlling a braking hydraulic pressure for the wheel under a non-braking condition. The slip rate of a wheel is controlled, by controlling the braking hydraulic pressure for the wheel under a braking condition, so as to provide an anti-skid control. A start of the control of the slip rate is restricted by the anti-skid control. The control of the slip rate by the anti-skid control is applied commonly to the right and left drive wheels, while the control of the slip rate by the traction control is applied independently to the right and left drive wheels. The anti-skid control can be always properly carried out without being affected by the traction control.

    摘要翻译： 用于具有后左右驱动轮的车辆的滑动控制系统包括用于通过在非制动条件下控制车轮的制动液压来控制车轮的滑动速度的牵引控制。 通过在制动条件下控制车轮的制动液压来控制车轮的滑移率，从而提供防滑控制。 滑移率的控制开始受到防滑控制的限制。 通过防滑控制的滑移率的控制通常适用于左右驱动轮，而通过牵引力控制的滑移率的控制独立地应用于左右驱动轮。 防滑控制可以始终正确执行，而不受牵引力控制的影响。

    摘要： A shift to control for retaining the braking force from the control for elevating the braking force is implemented when deceleration of the wheel exceeds a first predetermined threshold value when the wheels are braked. The first predetermined threshold value is so set as to become smaller as an assumed road surface friction coefficient .mu. is smaller. The first threshold value is further altered to a larger value by altering the assumed road surface friction coefficient .mu. to a higher one when the period of time required from the start of the control for elevating the braking force to the start of the following control for retaining the braking force is equal to or shorter than a predetermined period of time.

    摘要： A vehicle automatic transmission including a torque converter and a multiple stage transmission gear mechanism. The gear mechanism is controlled through a hydraulic system having solenoid valves. An electronic control unit is provided to control the hydraulic system under a shift control map having shift up and shift down control lines. The shift down control line is determined in terms of the torque converter turbine speed and the engine throttle valve position as a line in which the torque converter is operated with a torque ratio of substantially one.

    摘要： A slip control apparatus is designed such that an output from the engine is rapidly reduced to a set limit value by a feed-forward control when a friction coefficient on pavement gets large and the engine output reduced to the set limit value is then returned to a set return value larger than the set limit value by the feed-forward control. After returning to the set return value, the engine output is subjected to feed-back control so as to turn a slip value of the driven wheel to a target value. The set limit and return values can be changed in accordance with the friction coefficient on pavement and a vehicle speed. The set limit and return values can be corrected in a direction in which they become larger when the slip value gets larger on account of the upshifting of the transmission.

    摘要： A steplessly variable vehicle transmission of a belt-pulley type which is provided with an electronic control unit for controlling the speed ratio of the transmission in accordance with the engine operating condition, such as the engine load and the engine speed. The control unit has a shift control map which includes a shift-up zone, a shift-down zone and a speed ratio hold zone between the shift-up and shift-down zones so that the speed ratio of the transmission is maintained constant in acceleration and deceleration as long as the engine operating condition is in the hold zone.
