The invention discloses an automobile braking energy recovery method considering a driving style. The method comprises the steps that the driving style of a driver and the comfortable time headway of the corresponding style are determined; wherein the driving styles comprise aggressive styles, ordinary styles and prudent styles; when the real-time headway is larger than the safe headway, the current braking intention of the driver is recognized according to the current accelerator pedal position, the accelerator pedal change rate and the difference value of the real-time headway relative to the comfortable headway; the types of the braking intention comprise light degree, light-medium degree, medium strength and emergency; if the current braking intention of the driver is mild or mild, a regenerative braking strategy is adopted; if the current braking intention of the driver is moderate, a regenerative braking and mechanical braking mixed strategy is adopted; and if the current braking intention of the driver is emergency, a mechanical braking strategy is adopted. The driving intention recognition accuracy can be improved, so that the driving comfort and the braking energy recovery efficiency are improved.
本发明公开了一种考虑驾驶风格的汽车制动能量回收的方法,包括:确定驾驶员的驾驶风格和对应风格的舒适车头时距;其中驾驶风格包括激进型、普通型和谨慎型;当实时车头时距大于安全车头时距时,根据当前的加速踏板位置、加速踏板变化率以及实时车头时距相对于舒适车头时距的差值,识别驾驶员当前的制动意图;所述制动意图的类型包括:轻度、轻中度、中强度以及紧急;若驾驶员当前的制动意图为轻度或者轻中度,则采取再生制动策略;若驾驶员当前的制动意图为中强度,则采取再生制动与机械制动的混合策略;若驾驶员当前的制动意图为紧急,则采取机械制动策略。本发明可以提高驾驶意图识别的准确性,从而提高驾驶舒适性、制动能量回收的效率。
