Abstract

A control method of a brake lamp and a center high mounted stop lamp (CHMSL) of a vehicle. If the vehicle is not braking, both lamps are turned off. If the vehicle is braking, the method includes: receiving data on an operating state of the vehicle; determining a degree of danger based on the data; and operating the lamps based on the degree of danger. Operating the lamps includes: if the degree of danger is high, flashing the brake lamp quickly with high brightness, and flashing the CHMSL; if the degree of danger is medium, flashing the brake lamp slowly with high brightness, and turning on the CHMSL; and if the degree of danger is low, turning on both lamps. The data include an anti-lock brake operating state, deceleration of the vehicle, lateral acceleration of the vehicle, speed of the vehicle, and/or distance to a front obstacle.

Claims

1. A control method of a warning device of a vehicle, comprising:

if the vehicle is not braking, turning off the warning device; and

if the vehicle is braking;

receiving data on an operating state of the vehicle;

determining a degree of danger based on the data; and

operating the warning device based on the degree of danger.

2. The method of claim 1, wherein the warning device comprises a lamp.

3. The method of claim 2, wherein the operating the warning device comprises:

if the degree of danger is high, flashing the lamp at a high speed with a high brightness;

if the degree of danger is medium, flashing the lamp at a low speed with the high brightness; and

if the degree of danger is low, turning on the lamp at a low brightness.

4. The method of claim 1, wherein the data comprise at least one member of the group consisting of an anti-lock brake operating state;

a deceleration of the vehicle;

a lateral acceleration of the vehicle;

a speed of the vehicle; and

a distance to a front obstacle.

5. The method of claim 1, wherein the warning device comprises a plurality of warning devices.

6. The method of claim 5, wherein the warning devices comprise a first and a second lamp.

7. The method of claim 6, wherein the operating the warning devices comprises:

if the degree of danger is high, flashing the first and second lamps;

if the degree of danger is medium, flashing the first lamp and turning on the second lamp; and

if the degree of danger is low, turning on the first and second lamps.

8. The method of claim 6, wherein the first lamp is a brake lamp and the second lamp is a center high mounted stop lamp.
