摘要： A device for controlling the slip between driving wheels and a road surface during a start and an acceleration of a vehicle is maintained at a level which ensures a good acceleration and straight line running stability. The device determines a target speed of the rotation of the driving wheels, and controls a drive torque of the driving wheels in such a manner that the actual speed of the rotation of the driving wheels coincides with the target speed. Also, the device detects a friction coefficient between the driving wheels and the road surface, and the slippage of the driving wheels is controlled on the basis of the friction coefficient. Further, the device determines the reliability of the detected friction coefficient, and uses the detected friction coefficient only when the detected friction coefficient is determined to be reliable.

摘要： An acceleration slip control device for a vehicle, by which the slip between driving wheels and a road surface during a start and an acceleration of a vehicle is maintained at level ensuring a good acceleration and straight line running stability. The device controls the slippage of the driving wheel by adjusting a drive torque according to the amount of a deviation of the actual speed of rotation of the driving wheels from a target speed of the driving wheels. The drive torque is controlled in such a manner that the rate of change of the drive torque includes a component proportional to the rate of change of the slippage of the driving wheels and the proportional factor is selected in such a manner that the proportional factor is larger when the component acts to increase the drive torque and is smaller when the component acts to decrease the drive torque.

Repeatedly a first quantity representing the desired amount of fuel to be supplied to the combustion chambers in the next fuel injection pulse, a second quantity representing the proportion of fuel in one pulse which will adhere to the walls of the intake system, and a third quantity representing the proportion of fuel adhering to these walls which will be sucked off into the combustion chambers between two successive pulses are determined, based upon sensed values of certain operational parameters. Simultaneously, at proper injection time points in the engine's operational cycle, first from the third quantity and a fourth quantity representing the total fuel amount adhering to the walls a fifth quantity representing the actual fuel amount sucked off from the walls between two successive pulses is determined; then from the first, second, and fifth quantities a sixth quantity representing the actual fuel amount to be injected in the next pulse is determined; then from the sixth and second quantities a seventh quantity representing the actual amount of fuel from the next pulse that will adhere to the walls is determined; next the fourth quantity is updated by adding the seventh and subtracting the fifth quantity, and next the fuel injection valve is opened for a time corresponding to the sixth quantity.

摘要： A slip control device for a vehicle provided with an internal combustion engine, wherein an engine output torque is controlled independently of a depression of the accelerator pedal so that slip at the driving wheels of the vehicle is controlled. A stand-by means is provided and operates, upon a prediction of an occurrence of slip at the vehicle wheels, to close the throttle valve to a stand-by degree of opening thereof before the occurrence of the slip. The stand-by degree of opening of the throttle valve is controlled in accordance with an engine torque of the engine when the occurrence of slip is predicted. Thus the occurrence of slip is effectively prevented and a good acceleration performance obtained.
