The invention relates to the field of load throwing, in particular to a load throwing method and a vehicle control system. The vehicle control system comprises a vehicle control unit, a DCDC converter and an energy consumption module, the vehicle control unit is connected with the DCDC converter and the energy consumption module, the vehicle control unit executes the method, and the method comprises the steps that the output power of the DCDC converter is detected; if the output power of the DCDC converter is greater than or equal to a first threshold value, determining a target load throwing level according to a difference value between the output power and the first threshold value and/or a duration in which the output power is greater than or equal to the first threshold value; and according to a load rejection strategy associated with the target load rejection grade, executing load rejection on the energy consumption module. According to the load throwing method provided by the embodiment of the invention, the load throwing grades are graded, so that the purposes of protecting the DCDC converter and keeping the driving safety of the vehicle are achieved.
本发明涉及抛负载领域,尤其涉及一种抛负载方法和车辆控制系统。所述车辆控制系统包括整车控制器、DCDC转换器和耗能模块,整车控制器与DCDC转换器和耗能模块连接,整车控制器执行所述方法,包括:检测DCDC转换器的输出功率;若所述DCDC转换器的输出功率大于或等于第一阈值,则根据所述输出功率与所述第一阈值的差值,和/或所述输出功率大于或等于所述第一阈值的持续时长,确定目标抛负载等级;根据目标抛负载等级关联的抛负载策略,执行对耗能模块的抛负载。本发明实施例提供的抛负载方法通过对抛负载等级进行分级,实现了保护DCDC转换器,并保持车辆行驶安全的目的。
