The invention discloses a hybrid electric vehicle energy recovery control method based on a P2.5 + P4 configuration. The hybrid electric vehicle energy recovery control method comprises the steps that the regeneration capacity of a power assembly is estimated; energy recovery demand types are recognized, wherein the energy recovery demand types comprise sliding energy recovery, braking energy recovery and braking and sliding conversion; if the sliding energy is recovered, setting a corresponding sliding recovery torque according to the sliding energy recovery strength; if the braking energy is recovered, the braking regeneration torque is responded and controlled according to the braking regeneration torque request; and if braking and sliding are switched, zero crossing torque control is executed when sliding energy recovery is not started, gradient management is carried out on the braking torque until torque zero crossing is finished, and then the braking torque is executed according to a braking strategy. According to the hybrid vehicle energy recovery control method based on the P2.5 + P4 configuration, the reasonability of dual-motor energy recovery control is considered, so that the whole vehicle has an excellent energy recovery management system, the oil consumption is reduced, the driving comfort of a user is improved, and the experience feeling is improved.
本发明公开了一种基于P2.5+P4构型的混动汽车能量回收控制方法,包括:预估动力总成再生能力;识别能量回收需求类型,包括滑行能量回收、制动能量回收和制动与滑行转换;若为滑行能量回收,则根据滑行能量回收强度设置对应的滑行回收扭矩;若为制动能量回收,则根据制动再生扭矩请求,响应控制制动再生扭矩;若为制动与滑行转换,则在未开始滑行能量回收时,执行穿零扭矩控制,并对制动扭矩进行梯度管理,直到扭矩穿零结束,然后按照制动策略执行制动扭矩。本发明的一种基于P2.5+P4构型的混动汽车能量回收控制方法,兼顾双电机能量回收控制的合理性,使整车具备优良的能量回收管理体系,降低油耗,提升用户驾驶舒适性,提升体验感。
