Wheel rotation locking sensing reminding method and system based on hub motor
The invention relates to a wheel rotation locking sensing reminding method and system based on a hub motor. The method comprises the steps that a controller obtains a brake pedal treading depth signal at the first moment in real time; the controller obtains the current actual wheel speed in real time based on the first moment treading depth signal; the controller obtains a brake pedal treading depth signal at a second moment in real time and records the brake pedal treading depth signal as a second moment treading depth signal; the controller obtains the wheel speed at the second moment; a current actual wheel speed change rate is calculated; a current real-time wheel speed change threshold value is obtained; and whether the current actual wheel speed change rate is larger than the current real-time wheel speed change threshold value or not is judged, and if so, a wheel locking alert is generated. Compared with the prior art, the cost is reduced, the overall reliability of the ABS system is improved, meanwhile, the change relation of the maximum wheel speed change rate along with a brake pedal treading depth signal is considered, the method is suitable for more driving environment scenes, and the safety performance is greatly improved.
本申请涉及一种基于轮毂电机的车轮转动抱死传感提醒方法及系统，包括所述控制器实时获取第一时刻的刹车踏板踩踏深度信号；所述控制器基于所述第一时刻踩踏深度信号实时获取当前实际轮速；所述控制器实时获取第二时刻的刹车踏板踩踏深度信号并记为第二时刻踩踏深度信号；所述控制器获取第二时刻轮速；计算得到当前实际轮速变化率；获取当前实时轮速变化阈值；判断所述当前实际轮速变化率是否大于所述当前实时轮速变化阈值，若判断为是，则生成车轮抱死警醒。本发明与现有技术相比，降低了成本，还提高了ABS系统整体的可靠性，同时考虑了最大轮速变化率随刹车踏板踩踏深度信号的变化关系，适用于更多的驾驶环境场景，极大提升安全性能。
