Test method, test device and test system of intelligent driving system

The invention relates to the field of new energy vehicles, and provides a test method, a test device and a test system of an intelligent driving system. The method comprises the following steps: driving and controlling a tested vehicle to automatically run according to a target intelligent driving test path; if it is determined that the tested vehicle does not run to the end point of the path according to the real-time path information, intercepting and filtering a first message data set sent by the intelligent driving system to a chassis controller of the tested vehicle, obtaining a filtered data set, and forwarding the filtered data set to the chassis controller; if it is determined that the tested vehicle has driven to reach a path end point according to the real-time path information, automatic driving control over the tested vehicle is stopped, virtual obstacle information is constructed, and the virtual obstacle information is sent to the intelligent driving system; and forwarding a second message data
