中文摘要	High engine output torque may lead to high slip ratios of driven wheels and low utilization of road friction coefficients on a slippery road. The concept of optimum driven torque control was introduced to solve this problem. With consideration of both theoretical analyses and experimental data, the vehicle reference velocity was used to estimate the road friction coefficient and calculate the optimum driven torque. The optimum driven torque control was realized by controlling the dynamic engine output torque with a PID controller. Experiments with real vehicles show that this method can control the engine output torque and keep the driven wheel slip ratio in the optimum slip ratio region, with road-tire friction coefficient utilization rates of higher than 90%. Therefore, this method improves the vehicle acceleration ability on a slippery road.
