The invention belongs to the technical field of gear adaptive control, and particularly provides a target gear calculation method and a gear control method for a power split type hybrid light truck, and the calculation method comprises the following steps: dividing a vehicle speed range according to a set speed interval; meanwhile, the power range is separated according to a set power interval to generate a speed power list; respectively calculating a target gear value of the vehicle under the power corresponding to each vehicle speed in the speed power list under the pure electric mode by setting a torque ratio coefficient distributed to the driving motor, and filling the target gear value into a corresponding gear table; respectively calculating a target gear value of the vehicle under the power corresponding to each vehicle speed in the speed power list in the hybrid mode by setting a power proportion coefficient distributed to a planet row, and filling the target gear value into a corresponding gear table; and smoothing the filled gear table to generate a gear map gear shifting target table. According to the calculation method, gear control is carried out, power interruption and gear switching are avoided, and vehicle energy profit and loss are reduced.

    本发明属于挡位自适应控制技术领域,具体提供一种功率分流式混动轻卡目标挡位计算方法、挡位控制方法,所述计算方法包括如下步骤:将车速范围按设定速度间隔进行分隔,同时将功率范围按照设定功率间隔进行分隔生成速度功率列表;通过设置分配给驱动电机的扭矩占比系数分别计算车辆在纯电动模式下速度功率列表中每个车速对应功率下的目标挡位值,填入对应的挡位表中;通过设置分配给行星排的功率占比系数分别计算车辆在混动模式下速度功率列表中每个车速对应功率下的目标档位值,填入对应的挡位表中;对填充后的挡位表进行平滑处理生成挡位图换挡目标表。根据本发明的计算方法进行挡位控制,无动力中断挡位切换,减少车辆能量损益。
