摘要： In an antiskid brake system for a vehicle, the braking pressure applied to a wheel is reduced when the deceleration of the rotational speed of the wheel reaches a predetermined value and is increased when the acceleration of the rotational speed of the wheel reaches a predetermined value after reduction of the braking pressure. In a low vehicle speed range lower than a predetermined vehicle speed, the braking pressure is increased at a predetermined rate when the acceleration of the rotational speed of the wheel reaches the predetermined value after reduction of the braking pressure. The predetermined rate is independent from the rotational speed of the wheel and is changed with the friction coefficient of the road surface so that it reduces as the friction coefficient of the road surface reduces.

摘要： A slip control system for a motor vehicle controls slips in driving wheels and includes a sensor for detecting a slip ratio of each driving wheel and a traction control system for decreasing a slip of each driving wheel by controlling a driving force transmitted to each driving wheel so that the slip ratio of each driving wheel is at least equal to a predetermined desired slip ratio when the slip ratio of the driving wheel becomes equal to the desired slip ratio. An automatic transmission control system controls an automatic transmission by using a first shift property for a normal operation, and a second shift property for a traction control operation which is adapted to determine a relative higher speed stage. A device is provided for switching the first shift property to the second shift property when the traction control operation is started by the traction control system.

摘要： A slip control mechanism of a motor vehicle has a brake provided for each driving wheel, a first detection device means for detecting slip of each driving wheel, a second detection device for detecting if a predetermined condition has been met during a starting period of the vehicle, and a slip control device for operating the brake for providing each driving wheel with braking force when an excessive slip is detected, based on signals from the first detection device, to thereby eliminate such excessive slip. The slip control device controls the brake for the respective driving wheels whereby substantially the same amount of braking force is applied to the driving wheels when the second detection device detects that the predetermined condition is not met. The slip control device also controls the brake for the respective driving wheels independently in accordance with signals from the first detecting device when the second detecting device detects that the predetermined condition is met.

摘要： Slip control is carried out so as to reduce torque applied to the driven wheels by reducing torque generated by the engine when a slip value against the driven wheels on pavement is larger than a predetermined value. A shift characteristic of the automatic transmission interposed between the engine and the driven wheels is set as a first shift characteristic which is a basic characteristic at the time of ordinary running where no slip control is carried out and as a second shift characteristic set so as to become at least unlikely to cause downshifting during slip control compared with said first shift characteristic. As the slip control terminates, a return of the first shift characteristic is prohibited when the torque generated by the engine is large (for example, when a degree of operation of an accelerator is not zero) or when downshifting is caused if based on the first shift characteristics.

摘要： When the driven wheel of the vehicle slips against the road surface to a large extent, such a large slip of the driven wheel can be converged by reducing torque to be applied to the driven wheel by slip control, i.e., by control the throttle valve for adjusting a load of the engine in a direction of forcibly closing the throttle valve prior to operation of the accelerator. In a region of the opening angle of the accelerator nearby its full open region, for example, accounting for 75% or more, a control-unreactive region is provided which is unreactive to slip control, thereby preventing the throttle valve from lowering a given opening angle, for example, 25%. This arrangement can retain the opening angle of the accelerator nearby its full open position even if slip control cannot work normally, thereby ensuring an open state of the throttle valve and allowing the vehicle to run at least to a tune-up factory nearby.

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： A torque converter with a lockup clutch is interposed between an engine and a driven wheel, and the lockup clutch is coupled or uncoupled on the basis of a predetermined lockup characteristic. When a slip value of the driven wheel against a road surface reaches a given value or higher, torque to be applied to the driven wheel is decreased to thereby perform slip control. During this slip control, the lockup clutch is forced to be uncoupled prior to the lockup characteristic. The forcibly uncoupled state of the lockup clutch is maintained for a given period of time from the time when the slip control ends.

摘要： When a slip value of the driven wheel on a road surface reaches a predetermined value, the slip control is implemented to apply a braking force to the driven wheel as well as to decrease torque to be generated by the engine. When the brake is operated manually, or when a foot brake is stepped down, only the slip control by application of the braking force to the driven wheel is inhibited.

摘要： A traction control system for a vehicle has a sub-throttle valve provided in an intake passage of the engine in series to a main throttle valve which is operatively connected to an accelerator pedal to open and close in response to operation of the accelerator pedal. An engine output controller controls opening of the sub-throttle valve to control the output of the engine so that the slip value of the driving wheels converges on a target slip value. The engine output controller once moves the sub-throttle valve to an initial opening when the slip value of the driving wheels exceeds the target slip value and then controls the opening of the sub-throttle valve to control the output of the engine so that the slip value of the driving wheels converges on a target slip value. The initial opening is set to be a fixed value when the opening of the main throttle valve is not larger than a predetermined opening and to be substantially equal to the opening of the main throttle valve when the opening of the main throttle valve is larger than the predetermined opening. The fixed value is not smaller than the predetermined opening of the main throttle valve.
