Abstract: According to the mechanical characteristics and principles in this paper, the instantaneous speed determination of car collision in the traffic accident of car collision with electric two-wheeler is studied. Aiming at the different collision forms and angles between car and electric two- wheeler, the formula for calculating car speed at the moment of collision is given based on the principle of mechanical characteristics and the experience of related experiments. The content of this paper provides a more practical speed calculation method for the division of the traffic accident responsibility of the car collision with the electric two-wheel vehicle, in order to solve the problem of collision speed, play a helpful and enlightening role.

Key words: Collision electric two-wheeler; Instantaneous speed; Mechanical characteristics; Momentum conservation
