PURPOSE: To achieve collision at a target speed by automatically correcting the amount of reduction until the collision after disconnecting the towing of a vehicle to be experimented. CONSTITUTION: In a collision experiment device for achieving collision by controlling an electric motor 2 for driving a wire 4 for towing a vehicle to be experimented with a speed command VR in a specific pattern and disconnecting the towing in a constant-speed state after acceleration ends, an operation circuit 21 for obtaining a towing force F from an electric motor detection current I and a detection part 22 for detecting the end of acceleration from the towing force F are provided. Also, a memory part 23 for storing a friction FM of the towing device at a speed V at that time by driving the vehicle only with the towing device immediately before the experiment, a part 24 for setting a mass MV of the vehicle to be experimented, and an operation circuit 25 for obtaining an amount of reductionΔV from a driving resistance FL and an equivalent mass MV of the vehicle which is set by obtaining the driving resistance FL by subtracting the stored towing device friction FM from electric motor drive force after the end of acceleration are provided and then the amount of reductionΔV is added to a speed command VR for controlling the electric motor 2.
