The invention discloses an electric automobile abrupt slope slow descent control method and an automobile, and the method comprises the following steps: when the automobile meets the condition of entering an abrupt slope slow descent function, the automobile enters the abrupt slope slow descent function, and after the automobile enters the abrupt slope slow descent function, a battery SOC at the moment is collected; and when the SOC of the battery is greater than the maximum SOC threshold of energy recovery, the VCU controls the MCU to enter an ASC active short-circuit state. When the vehicle has no ESC and cannot perform abrupt slope slow descent through energy recovery torque braking, braking is performed by means of the torque generated by active short circuit of the ASC, so that the abrupt slope slow descent function is realized, the cost is low, and the safety and reliability of the vehicle are improved.
本发明公开了一种电动汽车陡坡缓降控制方法及汽车,其中方法包括:当汽车满足进入陡坡缓降功能条件后,车辆进入陡坡缓降功能,在进入该功能后,采集此时的电池SOC;当电池SOC大于能量回收最高SOC阈值时,此时VCU控制MCU进入ASC主动短路状态。本发明在车辆无ESC且无法通过能量回收扭矩制动进行陡坡缓降时,借助ASC主动短路产生的扭矩进行制动从而实现陡坡缓降功能,成本低、提高了车辆的安全性和可靠性。
