Zusammenfassung:	The utility model provides a complete vehicle test real-time speed display device, and belongs to the technical field of automobiles. The complete vehicle test real-time speed display device solves the problem that in a complete vehicle performance test, a device enabling a driver to know the practical speed of a vehicle is influenced by the temperature of a test room and can hardly make a due effect. The complete vehicle test real-time speed display device comprises a speed sensor of a chassis dynamometer, a logic controller, a wireless emitter and a housing. The housing is internally provided with a microprocessor and a wireless receiver in wireless communication with the wireless emitter. The surface of the housing is provided with a display screen used for displaying the practical speed of a tested vehicle. The speed sensor is connected with an input end of the logic controller. The wireless emitter is connected with an output end of the logic controller. The wireless receiver is connected with an input e
