The paper firstly analyzed the characteristic of vehicle road way test and the structure of the test system, and then brought up the development tendency of high reliability, high integration, synchronizing data acquisition, CAN communication interface, and so on. Thirdly, three key technologies were reviewed concretely in light of the industrialization requirement of vehicle dynamic stability control system, i.e. DSC, which include measurement method of the path and attitude of vehicle, the wheel force measurement technology and the steering input control method. The main stream of measurement technology for vehicle road way test in future may be the GPS only based measurement method of the path and attitude of vehicle, wheel force transducer based wheel force measurement method, the integration measurement of GPS devices and steer robot for the precisely steer control and path following road way tests.
