Vehicle safety device using visible light communication
First Claim
1. A vehicle safety apparatus using visible light communication, comprising:
- a brake sensor mounted to a brake pedal of a main vehicle to generate a deceleration signal according to a degree of braking;
an acceleration sensor mounted to an accelerator pedal of the main vehicle to generate an acceleration signal according to a degree of acceleration;
a visible light receiver configured to receive a preceding-vehicle signal from at least one preceding vehicle and a following-vehicle signal from at least one following vehicle;
a visible light transmitter configured to transmit a main vehicle signal to the preceding vehicle and the following vehicle;
a collision risk determinator configured to determine whether there is a danger of collision based on the preceding-vehicle signal, the following-vehicle signal and the main vehicle signal; and
an alarm configured to issue an alarm to a driver in response to the collision risk determinator determining the presence of a danger of collision.

Abstract
A vehicle safety device using visible light communication is disclosed. A vehicle safety apparatus using visible light communication includes a brake sensor on a main vehicle brake pedal for generating a deceleration signal by a degree of braking, an acceleration sensor on a main vehicle accelerator pedal for generating an acceleration signal by a degree of acceleration, a visible light receiver for receiving a preceding-vehicle signal from at least one preceding vehicle and a following-vehicle signal from at least one following vehicle, a visible light transmitter for transmitting a main vehicle signal to the preceding vehicle and vehicles, a collision risk determination unit for determining whether a danger of collision is present based on the preceding-vehicle signal, the following and main-vehicle signal, and an alarm unit for issuing an alarm to driver in response to the collision risk determination unit determining the presence of a danger of collision.
