The invention relates to the technical field of high-pressure oil tank pressure control, and particularly discloses a high-pressure oil tank refueling pressure control method and device, a hybrid vehicle and a storage medium. The method comprises the steps that when it is detected that a vehicle starts to be refueled, the current high-pressure oil tank temperature, the current oil level height and the current pressure value of the high-pressure oil tank are collected; the maximum pressure limit value of the current high-pressure oil tank is determined according to the current high-pressure oil tank temperature and the current oil level height; comparing the current pressure value with the maximum pressure limit value; and when the current pressure value is smaller than the maximum pressure limit value, the current refueling state is maintained. The technical problem that refueling is interrupted due to the fact that the pressure in the fuel tank is continuously increased along with rising of the fuel level in the refueling process is solved, and compared with the prior art, the refueling process of the hybrid vehicle can be smoother, and gun jumping is not prone to occurring.

    本申请涉及高压油箱压力控制技术领域,具体公开了一种高压油箱加油压力控制方法、装置、混动车辆和存储介质。方法包括:当检测到车辆开始加油时,采集当前高压油箱温度、当前油位高度和高压油箱的当前压力值;根据所述当前高压油箱温度和当前油位高度确定当前高压油箱的最大压力限值;比较所述当前压力值和最大压力限值;当所述当前压力值小于所述最大压力限值时,维持当前加油状态。解决了由于加油过程中油箱内部压力会随着油位的升高不断增加而出现的加油中断的技术问题,与现有技术相比,可以使混动车辆加油的过程更加顺滑不易跳枪。
