The invention relates to an electric automobile kinetic energy recovery and braking force recovery method and system. The system comprises a fly-by-wire brake pedal, a controller, an electric driving platform and a mechanical brake. The controller is connected with the fly-by-wire brake pedal. The controller is used for receiving a brake pedal treading depth signal sent by the fly-by-wire brake pedal, controlling the electric driving platform to execute configuration of total braking force matched with the brake pedal treading depth signal, and receiving a kinetic energy recovery current measurement value sent by the electric driving platform; the electric driving platform is included; and the mechanical brake is connected with the controller. The braking force distributed by the mechanical brake can be timely increased when the electric energy recovery braking force is suddenly reduced when the battery or a super capacitor is fully charged, the corresponding relation between the total braking force and the treading depth of the brake pedal is further ensured to be fixed, the hidden danger that the electric automobile with the kinetic energy recovery function has different braking force experiences is eliminated, and the driving safety is improved.
本申请涉及一种电动汽车动能回收与刹车力回收方法及系统,包括电传刹车踏板、控制器、电动驱动平台和机械刹车,所述控制器与所述电传刹车踏板连接,并用于接收所述电传刹车踏板发送的刹车踏板踩踏深度信号、用于控制所述电动驱动平台执行与所述刹车踏板踩踏深度信号匹配的总制动力的配置、用于接收所述电动驱动平台发送的动能回收电流测量值;所述电动驱动平台;所述机械刹车,与所述控制器连接。本发明实现在电池或超级电容充满电动能回收制动力突然降低时能及时增加机械刹车分配的制动力,进一步确保总制动力与刹车踏板踩踏深度的对应关系固定,消除了具有动能回收功能的电动汽车具有不同刹车制动力体验的隐患,提高了驾驶安全性。
