Problems solved by technology
Testing the VCU by means of prototype vehicle testing requires the assistance of prototype vehicle debuggers, which wastes the time and energy of the testers and is not safe.
If there is a problem during the commissioning of the prototype vehicle on site, the control strategy program set in the VCU cannot be changed or / and refreshed in time
[0004] Furthermore, there is still a disadvantage of testing the VCU in the way of prototype vehicle testing, that is, the test is not comprehensive. The normal control strategy set by the VCU can be tested on the prototype vehicle, but the control strategy of some abnormal functions cannot be tested on the normal control strategy of the prototype vehicle. Realized on the run

The invention discloses a test system for testing a vehicle control system and a method thereof. A controlled object model of a VCU is developed on a real-time simulation system work platform; the real-time simulation system work platform is in interaction with the VCU; according to the developed controlled object model of the VCU, test signals are sent to the VCU, and test result signals returned by the VCU are received. Since testing is carried out through simulating a sample vehicle test environment in a simulation mode, all sample vehicle signals can be simulated to carry out tests on the VCU; and the testing is safe and convenient.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to a testing system and method for testing a vehicle control system. Background technique [0002] Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important way to solve the energy crisis and environmental degradation. New energy vehicles can be electric vehicles or electric hybrid vehicles. [0003] In electric vehicles, the vehicle control system (VCU, Vehicle Control Unit) is an important core part, and its safe operation is the guarantee for the normal driving of electric vehicles. At present, the method of testing t...
