ECU detection and diagnosis control device

The utility model relates to an ECU detection and diagnosis control device. A central processing module (10) can exchange information with an external upper computer (100) through an upper computer communication module (20), and can exchange work information with an ECU (90) through an ECU communication module (50). A working condition simulation module (30) can be controlled by the central processing module to generate working condition simulation information. A signal simulation module (40) can be controlled by the central processing module to generate signal simulation information. An input signal generation unit (60) can be used to generate an input signal according to the above-mentioned information and send the input signal to the ECU to cause the ECU to work according to the input signal. An output signal acquisition module (70) can be used to acquire the output signal of the ECU to cause the central processing module to detect the ECU according to the output signal. The ECU detection and diagnosis con
