Automobile rear end collision early warning method and apparatus thereof

Abstract

The invention discloses a car-tracing-tail early warning method and device, adopting the first response action of the driver when he finds emergency in front to make the braking indicator light shine before the driver brakes, alarming the first tailing vehicle of the car speed control condition as quickly as possible and making other continuously tailing vehicles take predicted decelerating measures in succession. It is used before accident occurs. It has both necessities of rescuing imminent danger instantaneously after the event and of nipping in the bud instantaneously in advance all the more. It actively guards against the safety of the whole car.

Description

technical field [0001] The invention relates to an automobile rear-end collision early warning method and a device thereof. Background technique [0002] At present, expressways generally limit the maximum speed of vehicles to 110 kilometers per hour for small cars and 90 kilometers per hour for large vehicles. In fact, many vehicles exceed the maximum speed limit. According to the "Announcement of Violations and Speeding Vehicles on Expressway" by the Traffic Police Corps of the Guangdong Provincial Public Security Department (statistical date: July 9 to 15, 2003): there are 124 large vehicles with a speed of more than 110 kilometers per hour, and 124 vehicles with a speed of more than 120 kilometers per hour. 447 vehicles; 893 small cars with a speed of more than 130 kilometers per hour, and 4,682 vehicles with a speed of more than 140 kilometers per hour. Among the seriously violating vehicles announced on the website of the Guangdong Provi...

Problems solved by technology

[0014] In addition, when a vehicle is driving on a bustling road section or a low-speed section, it is precisely because of the low speed that drivers generally relax their vigilance, so that the distance between the front and rear of vehicles in the same lane is often less than the specified safety distance. Once the vehicle in front slows down or brakes suddenly, Unimaginable rear-end collisions often occur

Therefore, no matter the vehicle is running on a highway or a low-speed section (especially a highway), when the vehicle needs to slow down or brake at a critical moment, it is obviously necessary to light up the brake indicator light as soon as possible to send an early warning message to the trailing vehicle: but traditional The brake indicator light of the system fails to light up in the first reaction when the driver finds the situation ahead, and it must be turned on after the brake pedal is stepped on during the braking operation period.
