The invention particularly relates to a formula racing car traction force control method. The method comprises the following steps that S1, the optimal slip rate range of a racing car is calculated; s2, the speed and the wheel speed of the racing car are detected in real time, system noise and observation noise are removed through Kalman filtering, and whether the current driving wheel slip rate is in the optimal range or not is calculated; s3, the slip rate thresholds are set to be 20% and 60%, when the slip rate of the driving wheel is larger than 60%, rapid torque adjustment is adopted, and when the slip rate of the driving wheel is 20%-60%, slow torque adjustment is adopted; according to the invention, the measurement error of the vehicle speed and the wheel speed can be obviously reduced, so that the control system has higher precision and better stability, the use of a high-precision sensor is avoided, and the cost is reduced; the slip rate of the driving wheel is controlled within a target range, the dynamic property and the handling stability of the racing car are improved, and the driving force of the whole car is rapidly improved; the slip rate of the two driving wheels is adjusted to be kept within an ideal slip rate interval, and it is guaranteed that the racing car has good longitudinal adhesion performance.

    本发明具体涉及一种方程式赛车牵引力控制方法,其包括以下步骤:S1:计算赛车最佳滑转率范围;S2:实时检测赛车车速与轮速,通过卡尔曼滤波去除系统噪声与观测噪声,并计算当前驱动轮滑转率是否处于最佳范围;S3:设置滑转率门限为20%和60%,当驱动轮滑转率大于60%时采用快速扭矩调节,当驱动轮的滑转率在20%~60%时采用慢速扭矩调节;本发明能够显著减少车速与车轮速度的测量误差,使控制系统具有更高的精度与更好的稳定性,避免使用高精度传感器,减少成本;使驱动轮滑转率控制在目标范围内,提高赛车的动力性和操纵稳定性,迅速提高整车驱动力;调节两驱动轮的滑转率,使其保持在理想的滑转率区间内,保证赛车拥有较好的纵向附着性能。
