The invention provides an electricity guarantee control method for a hybrid vehicle, which comprises the following steps of: acquiring SOC (State of Charge) and required power of a vehicle power battery, and setting a corresponding relation table of the SOC, the required power and vehicle generated power; a vehicle hybrid control mode is selected according to the SOC and the required power, and if the vehicle gear is in a P/N gear and the SOC is smaller than a first electric quantity threshold value, the vehicle enters an idling power generation mode; when the vehicle runs normally, the running speed of the vehicle and the acceleration of the whole vehicle are obtained, and if the change value of the acceleration of the whole vehicle in a set time period is smaller than a first set threshold value, power generation output is conducted according to the vehicle power generation power obtained by looking up the corresponding relation table. The electric balance capacity of the whole vehicle can be improved, the driving experience is improved, and the energy-saving performance and intelligence of the vehicle are improved.
本发明提供一种混动车辆的保电控制方法,包括:获取车辆动力电池的SOC和需求功率,并设置所述SOC、所述需求功率与车辆发电功率的对应关系表;根据所述SOC和所述需求功率选取车辆混动控制模式,如果车辆挡位处于P/N挡,且所述SOC小于第一电量阈值,则车辆进入怠速发电模式;在车辆正常运行时,获取车辆运行的车速和整车加速度,如果所述整车加速度在设定时间段内的变化值小于第一设定阈值,则根据所述对应关系表查表得到的车辆发电功率进行发电输出。本发明能提高整车的电平衡能力,增加驾乘体验,提高车辆的节能性和智能性。
