The invention provides a vehicle controller software upgrading test system and a vehicle. The vehicle controller software upgrading test system is integrated with a master control ECU, an upper computer, an interface module and a communication module, is small in size and is convenient to carry, and an automatic test of site vehicle controller software upgrading can be achieved. During the test process, all data in the upgrading test process is recorded and analyzed by the upper computer, a test result and a fault reason are timely output, and subsequent software improvement and upgrading arefacilitated; and moreover, the upper computer is used for detecting upgrading software acquired from a background server by the communication module, a signal is sent to a control module by the uppercomputer after detection without error, and the control module controls to perform vehicle controller software upgrading.
Description
technical field [0001] The invention belongs to the technical field of automatic testing, in particular to a vehicle controller software upgrade testing system and a vehicle. Background technique [0002] Due to the increasingly prominent social energy and environmental problems, the application and development of pure electric vehicles has been raised to the level of national strategy and has developed rapidly. In pure electric vehicle technology, the vehicle controller, as one of the core components, determines the energy saving, power and comfort of pure electric vehicles. In order to meet the ever-increasing industry and customer needs, it is necessary to upgrade the software of the vehicle controller. At present, when the vehicle controller needs to update the upgrade program, manual on-site update is used, that is, the computer is connected with the CAN interface of the vehicle controller for flashing, and the upper computer is used for flashing. This method has obvi...
