The invention provides a vehicle testing method, device and system, and relates to the technical field of vehicle testing, and the method comprises the steps: obtaining the road condition information of a target road section from a cloud control platform, and constructing a digital twin simulation scene; a target test area is selected from the road condition information, vehicle to-be-tested parameters are calculated according to vehicle driving data in the target test area, and a corresponding virtual to-be-tested vehicle is constructed. Triggering the virtual to-be-tested vehicle to run in the digital twin simulation scene, and mapping the virtual to-be-tested vehicle in the digital twin simulation scene and the to-be-tested parameters of the virtual to-be-tested vehicle to the running vehicle in the target test area through the cloud control platform; and performing vehicle testing on the virtual to-be-tested vehicle based on the response of the running vehicle to the to-be-tested parameters of the vehicle. According to the invention, on the premise that the real vehicle does not need to participate in the target scene road, the congestion of the vehicle under the real road condition and the intelligent driving state of the vehicle driving on the road can be predicted, and the cloud-controlled in-the-loop intelligent driving test can be realized.
