Lifetime test system for hybrid electric vehicle controllers

A lifetime test system for hybrid electric vehicle controllers is provided that belongs to the testing technical field of vehicle controllers. The test system includes a controller group (60) which is arranged in an environmental cabin (20) and a test bench which is arranged with at least one pair of coaxial hybrid power motors (30); electric interface boxes (40) are arranged on the test bench which is electrically connected with a central control computer (10); and the central control computer (10) controls programmable power source and the controller group (60) and is connected with them via the electrical interface boxes (40); the controllers (60) are electrically connected with the hybrid power motors (30) correspondingly, wherein one hybrid power motor (30) works in a generating pattern and the other hybrid power motor (30) which is coaxially connected with the motor works in a motor pattern, the central control computer (10) transmits control signals to realize transmission of testing instructions and feedback of testing status, and monitors the system condition during testing and collects the testing results.
