A comprehensive performance test system for Automated Driving Vehicles related to the technical field of vehicle testing equipment. It solves the technical problem of testing Automated Driving Vehicles. The system comprises a base platform, a lateral moving platform mounted on the base platform, and a rotary platform mounted on the lateral moving platform; There are two front wheels' brackets in the front of the rotary platform which can slide left and right, and two front wheel track adjustment mechanisms to control the movement of left and right sliding of two front wheels' brackets; There are two rear wheels' brackets on the rear of the rotary platform which can slide front and back, and two wheelbase adjustment mechanisms to control the movement of front and rear sliding of two rear wheels' brackets. Each front wheel bracket is equipped with a dynamometer bracket which can rotate horizontally, and each front wheel dynamometer bracket is equipped with a rotary dynamometer and a motor for driving the rotation of the front wheel dynamometer. Each rear wheel bracket is equipped with a rear wheel rotary dynamometer and a load motor for driving the rotation of the real wheel rotary dynamometer. The system provided by the invention can test the longitudinal and lateral performance of Automated Driving Vehicles.
