Testing system and method of high-power automatic transmission control strategy

The invention discloses a testing system of a high-power automatic transmission control strategy. The system comprises a control system, a fixing rack, a variable-frequency motor, a high-power automatic transmission and an electric power loading device, wherein the electric power loading device is in transmission connection with an output of the high-power automatic transmission; torque and rotation speed sensors are arranged between the variable-frequency motor and the high-power automatic transmission and between the high-power automatic transmission and the electric power loading device respectively; and the torque and rotation speed sensors, the variable-frequency motor, the high-power automatic transmission and the electric power loading device are connected with the control system respectively. At the same time, the invention further discloses a testing method using the testing system, a power device is the variable-frequency motor, an engine is not taken as a power source, the variable-frequency motor can realize constant rotation speed control and constant torque control and is easy to control; accurate control of control strategies such as shift rules and the like can be realized, and parameter correction is facilitated.
