A rear vehicle assistance system for controlling an emergency notification device for a vehicle, the emergency notification device comprising:
- a base;
- a plurality of pole rods sequentially connected to the base;
- and
- a light emitting frame unit connected to the pole rods to be unfolded or folded in accordance with moving up or down of the pole rods,
- wherein the plurality of pole rods gradually changes in diameter in an antenna type to be sequentially accommodated in a pole rod having the largest diameter or unfolded outward from the pole rod having the largest diameter, and the plurality of pole rods is coupled with an elastic member therebetween when accommodated, and raised by elasticity of the elastic members when the elastic members are not locked, and
- the light emitting frame unit includes a first holder fixed to the upper end of a pole rod positioned at the uppermost end when unfolded of the plurality of pole rods, first and second light emitting frames each having an end rotatably connected to the first holder, and third and fourth light emitting frames each having an end rotatably connected to the other end of the each of the first and second light emitting frames, in which the third and fourth light emitting frames are formed to be shorter than the first and second light emitting frames, the third and fourth light emitting frames have the other ends rotatably connected to the upper end of a pole rod connected next to the pole rod positioned at the uppermost end, so when the pole rod positioned at the uppermost end is raised and the first and second light emitting frames are pulled, the ends of the third and fourth light emitting frames are pulled and unfolded,
- wherein the pole rods are locked by raising control protrusions such that raising is suppressed by the elastic member, an operation button for operating an operation of the raising control protrusion is disposed in the base, and the rear vehicle assistance system includes:
- an operation button driving unit controlling on/off of the operation button;
- a wire connected to a bottom surface of the first holder and wound on a winding roll disposed on the base through an inner space of the pole rods to move down the first holder, and a winding roll driving unit operating to wind or unwind the wire;
- and
- a controller operating the operation button driving unit and the winding roll driving unit such that the pole rods are raised and the light emitting frame unit is unfolded in the shape of a triangle reflector when a vehicle that is being driven is suddenly braked, a shock applied to the vehicle with predetermined intensity or more is sensed, a vehicle anti-collision system is operated, or a driving switch is manually pressed.
