Problems solved by technology
[0004] In the traditional technology, the brake light switch of the whole vehicle is independently controlled by the brake light switch, and the control of the brake light of the whole vehicle is realized through the switching of the switch state. When the power circuit between the high-mounted brake lights is disconnected, the function of the brake lights of the whole vehicle will fail. If the vehicle is in the process of driving at this time, when the vehicle brakes and decelerates, the probability of rear-end collision due to the failure of the brake lights of the vehicle will be greatly increased. Improve and affect vehicle driving safety

The invention relates to the field of automobile brake lamp control, in particular to a novel automobile brake lamp control system and method. The novel automobile brake lamp control system is characterized by comprising an ECU, a control switch, a body control unit (BCM) and a brake lamp assembly. The BCM and the brake lamp switch are adopted for jointly controlling a whole automobile left brake lamp, a right brake lamp and a high level brake lamp. A power supplies is additionally provided for the automobile left brake lamp, the right brake lamp and the high level brake lamp, wherein one power supply is directly controlled by the brake lamp switch, the other power supply is controlled by the BCM, and all the automobile brake lamps can work normally as long as the output of one of the two power supplies is valid. In this way, the working reliability of the automobile brake lamps is improved, the possibility that when a vehicle is braked during travelling, the vehicle does not remind vehicles behind on the road through the brake lamps, and vehicle rear-end collision occurs is reduced, and the vehicle travelling safety is improved.
Description
technical field [0001] The invention relates to the field of automobile brake light control, in particular to a novel automobile brake light control system and method. Background technique [0002] In order to reduce the occurrence of automobile rear-end collision accidents, vehicles generally use high-mounted brake lights. The high-mounted brake lights used in traditional vehicles use the same control method as ordinary brake lights (that is, they only indicate the normal driving or braking status of the vehicle by being on or off), without considering the actual braking conditions. The intensity is graded to light up. The driver of the rear car cannot clearly judge the braking strength of the vehicle in front according to the indication of the high-mounted brake light, and cannot clearly determine the driving status of the vehicle in front; When driving, the high-mount brake light and the running light are both red, which is easy to confuse and cause misjudgment.
