The invention provides a gear shifting control method and system of a hybrid vehicle, a storage medium and electronic equipment, and the method comprises the following steps: obtaining the current wheel side demand torque and the vehicle speed of the hybrid vehicle, and calculating the vehicle rotating speeds under different gears according to the current wheel side demand torque and the vehicle speed; engine loss cost, motor loss cost and battery pack loss cost corresponding to the different gears are sequentially obtained according to the vehicle rotating speeds under the different gears, and the total cost loss value under the different gears is calculated according to the engine loss cost, the motor loss cost and the battery pack loss cost; and according to the total cost loss values under the different gears, the gear corresponding to the loss optimal value is selected as a target gear, and the gear of the hybrid vehicle is switched to the target gear. According to the gear shifting control method of the hybrid vehicle, the cost loss of the vehicle when different gears are switched can be evaluated in an all-around mode, then the optimal gear is locked for switching, and the oil consumption loss of the vehicle can be reduced.

    本发明提出一种混动车辆的换挡控制方法、系统、存储介质及电子设备,该方法包括:获取混动车辆的当前轮边需求扭矩和车速,并根据所述当前轮边需求扭矩和车速计算不同档位下的车辆转速;根据不同档位下的车辆转速依次获取不同档位下分别对应的发动机损失成本、电机损失成本以及电池包损失成本,并根据所述发动机损失成本、电机损失成本以及电池包损失成本计算不同档位下的总成本损失值;根据不同档位下的总成本损失值选出损失最优值对应的档位作为目标档位,并将混动车辆的档位切换至目标档位。本发明提出的混动车辆的换挡控制方法,能够全方位地评估车辆在切换不同档位时的成本损失,进而锁定最佳的档位进行切换,有利于降低车辆油耗损失。
