The invention discloses a power generation control method, a power generation control system and a vehicle, a hybrid vehicle adopts a single clutch transmission, and the power generation control method comprises the steps that the current vehicle speed and the current SOC are obtained; if the current vehicle speed is lower than the first threshold value and the current SOC is lower than the second threshold value; acquiring a current engine gear; if the current engine gear is larger than the threshold gear, switching to the threshold gear, and if the current engine gear is smaller than or equal to the threshold gear, maintaining the current engine gear; the motor gear is switched to the power generation gear, and the engine is connected with the motor in series to drive the motor to generate power and drive the vehicle to run. Therefore, on one hand, the low-speed running characteristic of the vehicle can be improved while the electricity protection capacity of the vehicle is improved, and the influence on low-speed running of the vehicle is avoided; on the other hand, under the condition that the vehicle runs at a low speed for a long time, the electric quantity of the battery pack can be prevented from being too low, it is ensured that the motor can achieve torque compensation, and the power interruption phenomenon in the vehicle gear shifting process is avoided, so that the driving smoothness is improved.

    本申请公开了一种发电控制方法、发电控制系统以及车辆,混动车辆采用单离合变速器,包括:获取当前车速以及当前SOC;如果当前车速低于第一阈值且当前SOC低于第二阈值;获取当前发动机档位;如果当前发动机档位大于阈值档位,则切换至阈值档位,如果当前发动机档位小于等于阈值档位,则维持当前发动机档位;电机档位切换至发电档位,发动机与电机串联,以带动电机发电并驱动车辆行驶。由此,一方面,提高车辆的保电能力的同时,还可以改善车辆的低速行驶特性,避免对车辆的低速行驶造成影响;另一方面,车辆长时间低速行驶情况下,可以避免电池包电量过低,确保电机可以实现扭矩补偿,避免车辆换挡过程中,出现动力中断的现象,以提高驾驶平顺性。
