The invention discloses a control method and device for dynamic slope parking of a new energy automobile, relates to the technical field of new energy automobile electric control function strategies, and mainly aims at achieving dynamic control of slope parking and preventing the problems that a motor is overheated and the automobile cannot be parked on a steep slope for a long time due to the fact that the locked-rotor current of the motor is too large. According to the main technical scheme, when the vehicle enters a slope parking mode, the motor output torque of the vehicle is obtained; on the basis of the motor output torque, slope holding types are obtained through a preset dynamic adjustment rule, and the slope holding types at least comprise long-time slope holding and short-time intermittent slope holding; when the hill-holding type is the long-time hill-holding type, the vehicle keeps the long-time hill-holding; and when the hill-holding type is the short-time intermittent hill-holding type, the vehicle carries out dynamic hill-holding according to a preset intermittent hill-holding rule corresponding to the short-time intermittent hill-holding type. The method is used for slope parking of the new energy automobile.

    本发明公开了一种新能源汽车动态驻坡的控制方法及装置,涉及新能源汽车电控功能策略技术领域,主要目的在于实现动态控制驻坡,防止电机因堵转电流过大,导致电机过热,车辆不能过长时间驻停在陡坡上的问题。本发明主要的技术方案为:当车辆进入驻坡模式时,获取所述车辆的电机输出扭矩;基于所述电机输出扭矩,利用预设动态调整规则获取驻坡类型,所述驻坡类型至少包括长时间驻坡和短时间间歇式驻坡;当所述驻坡类型为所述长时间驻坡时,所述车辆保持长时间驻坡;当所述驻坡类型为所述短时间间歇式驻坡时,所述车辆根据所述短时间间歇式驻坡对应的预设间歇驻坡规则进行动态驻坡。本发明用于新能源汽车驻坡。
