Slip control system for automotive vehicle

Abstract

In performing slip control such as traction control or ABS control, a control degree for slip control is changed in accordance with a temperature of outside air, or outside air temperature. The slip control system enhances response to slip control on a road surface having a lower road surface friction coefficient .mu., or a slippery road, and prevent a frequent execution of slip control on a road surface having a higher road surface friction coefficient .mu., by appropriating the setting of the road surface friction coefficient .mu. in accordance with the outside air temperature. A mode of changing the control degree for slip control includes, for example, a change of the condition for starting slip control, a change of a target value for slip control, and a change of an initial value of the road surface friction coefficient .mu., in accordance with the outside air temperature.
