The invention discloses an electric vehicle torque active distribution system control strategy test platform. The test platform comprises an upper computer which is used for importing an electric vehicle torque active distribution system control strategy and calculating electric vehicle state simulation data under the control of an electric vehicle torque active distribution system under various typical driving working conditions; and an electric vehicle torque distribution system simulation bench which is used for simulating wheel speeds and driving torques of different driving wheels of the vehicle under actual working conditions. The upper computer is electrically connected with the electric vehicle torque active distribution system simulation bench. By using the test platform, the problems of high risk, long period, high cost, poor repeatability and the like of the real vehicle road test in the electric vehicle torque active distribution system control strategy test process are solved. The test platform can be widely applied to the field of test platforms.
Description
technical field [0001] The invention relates to the field of test platforms, in particular to a control strategy test platform for an active torque distribution system of an electric vehicle. Background technique [0002] The main structural feature of distributed drive electric vehicles is that the drive motor is directly installed in or near the drive wheel, which has the outstanding advantages of short drive transmission chain, efficient transmission, and compact structure. Due to its unique form of dynamics control, distributed drive electric vehicles have significant advantages in terms of maneuverability. The active torque distribution of the left and right wheels of the front axle can generate power steering and realize the steering portability of the whole vehicle; the active distribution of torque of the left and right wheels of the rear axle can improve the response of the vehicle yaw rate and realize the sensitivity and stability of the vehicle control. The test ...
