The invention provides a steady-state self-adaptive synchronous updating method based on torque. The method comprises the steps that the torque in a torque model is divided into a plurality of torque areas; dividing a torque area into a high-frequency area and a low-frequency area; according to the self-adaptive activation times and the self-adaptive error value, judging whether self-adaption in the high-frequency region is converged or not; and correcting the torque pressure diagram of the low-frequency region by using the average slope of the converged torque pressure diagram of the high-frequency region. According to the method, the torque range which is difficult to activate and self-adaptive is synchronously updated according to the self-adaption of the torque of the high-frequency region, so that the performance of the whole vehicle is rapidly stable.

    本发明提供一种基于扭矩的稳态自适应同步更新的方法,包括:将扭矩模型中的扭矩划分为多个扭矩区域;将扭矩区域划分为高频区和低频区;根据自适应激活次数和自适应误差数值判断在高频区自适应是否收敛;利用高频区收敛后的扭矩压力图的平均斜率修正低频区的扭矩压力图。提供的方法实现根据高频区的扭矩的自适应同步更新较难激活自适应的扭矩范围,使整车性能快速达到平稳。
