Abstract

The invention relates to a reliability test system and method for a vehicle body controller. The reliability test system comprises a test cabinet, and an upper computer and a temperature box which areconnected with the test cabinet, the test cabinet comprises an I/O interface, a communication interface, a cabinet, and an industrial personal computer, a real-time processor, a test board card, a signal conditioning module, a programmable DC power supply and an analog load box which are arranged in the cabinet. The test cabinet simulates and provides an input signal required by a test for the vehicle body controller, and meanwhile, the simulation load receives an output signal of the vehicle body controller; the temperature box is used for providing various temperature test conditions, highand low temperature alternating test conditions and damp and hot test conditions for the vehicle body controller; and the upper computer achieves hardware configuration and test deployment of the testsystem, monitors the working state of the vehicle body controller in real time through an operation interface, records data, establishes a database and generates a test report. The system is convenient to operate, accurate in measurement, high in reliability and high in test comprehensive capacity.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of vehicle body controllers, and in particular relates to a system and method for reliability testing of vehicle body controllers. Background technique [0002] With the continuous improvement of people's vehicle safety and comfort, the rapid development of automotive electronic technology, the system components in the car are becoming more and more diverse and complex.
