The application discloses a vehicle testing
system, a vehicle testing method and a device. The
system comprises a vehicle
simulation platform configured to receive first data and second data, wherein the first data and the second data are configured to describe force conditions of a longitudinal
control system and a lateral
control system on a vehicle respectively. The vehicle
simulation platform is further configured to input the first data and the second data into a
vehicle dynamics model to obtain a longitudinal load and a lateral load. A distributed loading testing
system is configured to receive the longitudinal load and the lateral load, load the longitudinal load to the longitudinal
control system, load the lateral load to the lateral control system, and monitor an operating state of the vehicle. Through the application,
coupling characteristics of a power domain and a
chassis domain under a real operating state of a vehicle can be accurately simulated, and tests under unstable boundary conditions and
operating limit conditions such as large turning angles and high speeds can be covered.
