7. The device of claim 5, wherein the feedback module is further configured to:
and if the capacity threshold value is not reached, storing the braking energy generated when the target vehicle brakes in an energy storage element carried by the target vehicle.
8. The device of claim 5, wherein the feedback module is further configured to:
determining whether energy possessed in the vehicle other than the target vehicle reaches an energy threshold;
and if the energy threshold is reached, storing the braking energy generated when the target vehicle brakes in an energy storage element carried by the target vehicle.
