The invention discloses a hybrid vehicle single pedal braking energy recovery method and device and a storable medium, and relates to the technical field of vehicle control, and the method comprises the following steps: obtaining pedal position information and vehicle speed information of an accelerator pedal, and inputting the pedal position information into a pedal dynamics model for processing, obtaining a pedal position variable quantity and a pedal position change gradient; according to the pedal position information and the pedal position variable quantity, the driving intention of a driver is recognized, corresponding driving intention and braking intention parameters are obtained, and whether energy recovery is conducted or not is judged. Aiming at the characteristic that the parallel hybrid electric vehicle has a pure engine driving mode, the invention provides a control strategy for recovering braking energy while providing braking torque by using a motor in the mode to meet the requirement of vehicle deceleration.
本发明公开了一种混动汽车单踏板制动能量回收方法、装置及可存储介质,涉及整车控制技术领域,其中方法包括以下步骤:获取加速踏板的踏板位置信息及车速信息,并将所述踏板位置信息输入至踏板动力学模型进行处理,得到踏板位置变化量及踏板位置变化梯度;根据所述踏板位置信息及所述踏板位置变化量对驾驶员的驾驶意图进行识别,得到对应的驾驶意图及制动意图参数,并判断是否进行能量回收等步骤;本发明针对并联式混合动力汽车具备纯发动机驱动模式的特点,提出了在该模式下利用电动机提供制动力矩以满足车辆减速需要地同时,进行制动能量回收的控制策略。
