TCS strategy based on integrated control of engine torque and automatic transmission gear was designed, and then the control logic was proposed. The dynamic model of vehicle starting and accelerating process was built, and the simulation model was established with Matlab. Some simulations of vehicle running on icy and snowy road were processed. The results indicated that the TCS strategy based on integrated control of engine and automatic transmission could control the slippage ratio of the driven wheel effectively, thus the capability of vehicle starting and accelerating on icy and snowy road has been increased. The study provided some theoretical reference to the consecutive research.
