Function testing device of integrated brake controller

The invention discloses a function testing device of an integrated brake controller. The function testing device comprises an assembly mounting mechanism, an electric push cylinder and a rapid clamping mechanism, the assembly mounting mechanism comprises a mounting seat, and a test space is formed on the mounting seat; the ABS actuating mechanism is mounted on the mounting seat, and a pedal input end of the ABS actuating mechanism penetrates through the mounting seat and extends into the test space; the electric push cylinder is arranged in the test space, and an output shaft of the electric push cylinder faces the pedal input end and is used for pushing the pedal input end to act; and the quick clamping mechanism is mounted on the mounting seat and is used for pressing the tested ECU or releasing the ABS actuating mechanism so as to realize connection or disconnection between the tested ECU and the ABS actuating mechanism. The function test device is used for solving the problems that the mounting and dismou
