Slip control device for automobile

Abstract

Abstract PURPOSE:To improve the convergent property and return responsiveness of slip by conducting a feedforward control to reduce and return the output of an engine according to the coefficient of friction of a road surface and the vehicle speed when a slip occurs in a driving wheel. CONSTITUTION:The output of an engine 1 is regulated by a means 10 to prevent the slip of a driving wheel. When the occurrence of a slip is detected by each means 24, 24', then, the means 10 is feedforward controlled by a means 25 so that the output of the engine 1 is reduced to a set limiting value. When a determined time is passed after reducing the output of the engine 1, the means 10 is controlled by a means 26 so that the output of the engine is returned to a set return value. The set limiting value and set return value are determined at least according to the coefficient of friction of a road surface and the vehicle speed. When a shift-up of a transmission is detected by a means 28, the set limiting value is corrected to the output increasing side of the engine by a means 29.
