The invention discloses a speed-measuring function test platform for a vehicle-mounted system for measuring the speed based on a speed sensor. A test object is the speed-measuring function of the vehicle-mounted system for measuring the speed based on the speed sensor; speed sensor or acceleration sensor information which is calculated through the set model is input into the vehicle-mounted system; and testing of the speed-measuring algorithm function of the vehicle-mounted system can be achieved for testing personnel on a software view. The testing platform is capable of acquiring acceleration information which is close to that of a real vehicle as much as possible by vehicle stress analysis without complicated speed-measuring filtering and slipping judgment algorithms, and simulating the vehicle slipping scene through dynamic slip rate control, so that the input signal of the vehicle-mounted system is relatively close to that of the real vehicle, and a relatively accurate test effect is achieved.
