The invention relates to the technical field of automobiles and discloses an upshift control method, device and equipment and a storage medium. According to the method, the current whole vehicle driving working condition is obtained, the target gear is determined according to the current whole vehicle driving working condition, then upshift operation is executed according to the target gear, torque compensation is conducted when torque exchange starts so as to increase the torque of a wheel end, then torque compensation is stopped when torque exchange ends, and the rotating speed of the engine is adjusted; and then whether upshift of the vehicle succeeds or not is judged according to the adjusted engine rotating speed and the target gear rotating speed corresponding to the target gear. The method is advantaged in that torque compensation is carried out when torque exchange starts to increase the wheel end torque, torque compensation is stopped when torque exchange ends, the wheel end torque can be effectively compensated, and then whether upshift of the vehicle succeeds or not is judged according to the adjusted engine rotating speed and the target gear rotating speed corresponding to the target gear; therefore, gear shifting jerking caused by different gear speed ratio differences and energy loss in the upshift process can be effectively compensated.

    本发明涉及汽车技术领域,公开一种升挡控制方法、装置、设备及存储介质。本发明通过获取当前整车行驶工况,并根据当前整车行驶工况确定目标挡位,然后根据目标挡位执行升挡操作,并在扭矩交换开始时进行扭矩补偿,以增加车轮端扭矩,然后在扭矩交换结束时停止扭矩补偿,并对发动机转速进行调整,再根据调整后的发动机转速和目标挡位对应的目标挡位转速判断车辆是否升挡成功。本发明在扭矩交换开始时进行扭矩补偿,以增加车轮端扭矩,并在扭矩交换结束时停止扭矩补偿,能够有效补偿车轮端扭矩,再根据调整后的发动机转速和目标挡位对应的目标挡位转速判断车辆是否升挡成功,从而能够有效补偿因不同挡位速比差、能量损失导致的升挡过程换挡顿挫。
