Abstract
A power train control system for controlling power to be transmitted to a traction wheel of a vehicle from a vehicle engine through an automatic transmission shifts its speed range according to shift patterns depending upon speed of the vehicle and a load of the vehicle engine. When slippage occurring on the traction wheel is detected, the automatic transmission is caused to shift its speed range according to a specific shift pattern for traction control which predetermined according to at least a rotational speed of a driven wheel of the vehicle so as to control the power transmitted to the traction wheels from the vehicle engine, thereby eliminating the slippage.
