Life-saving technology ------Aoten anti-collision warning system

The invention of the automobile greatly improved productivity and people's convenience of life, but at the same time it also brought about the untold pain of casualties in traffic accidents. Not long ago, the Yanan bus tail-burning accident led to the disappearance of more than 30 lives, deeply stinging the hearts of motorists, especially those who are engaged in automotive safety technology. Hangzhou Aoteng Electronics, as an automotive electronics company, is even more saddened.

Autun has been developing the ADAS for many years. Our ADAS core product anti-collision warning system was developed based on the world's leading image recognition technology, which was adopted on BMW and Volvo. The anti-collision warning system has the following functions:

1. Frontal Collision Warning (FCW). Alerts drivers to alert to an upcoming rear-end collision with a vehicle or locomotive ahead. The system can calculate the collision time based on the distance and relative speed between two vehicles.

2. Urban Front Collision Warning (UFCW). In the case of low speeds, bumper-to-bumper, and rear-end collisions, warnings about the impending collision risk in front of the vehicle are generally referred to in urban or dense traffic conditions. Also called the virtual bumper feature.

3. Pedestrian crash warning (PCW), including bicycle detection. An audition warning warns the driver of an impending collision with a pedestrian or a bicycle.

4. Lane Departure Warning (LDW). If you do not intend to deviate from the lane, it may lead to accidents such as driving out of the road, overturning, etc., and alerting the driver through trial listening. The system can measure the distance between the two wheels and the lane standard line.

5. Vehicle distance monitoring and warning (HMW). Many drivers overestimate the distance from the front, and do not realize that the effective distance will decrease as their spacing increases, so that they do not have enough time to react. The speed warning function provides audition warnings when the distance between the front wheels is severely shortened.

6. Speed ​​Limit Identification (SLI). It can automatically identify the speed limit sign on the highway and give an alarm after speeding.

7. Intelligent high beam (IHC). Depending on whether the lights are bright or dark, whether there is a car in front of you, or if you are in a car, smartly turn on and switch the lights from far and near.

8. In conjunction with the AoTeng CAN controller, when the alarm condition is reached at the time of collision and lane departure, the brake light, double flash and turn signal can be turned on respectively to play the role of prompting the vehicle.

9. In close cooperation with the main engine plant, the auxiliary brake function can be provided to achieve emergency braking under dangerous conditions.

The working principle of the anti-collision warning system is as shown in the figure, which uses advanced road and vehicle visual monitoring systems to monitor objects in the range of approximately three lanes in front of the road.

Based on monitoring, advanced vehicles, pedestrians and road visual recognition technologies are used to target the target.

After the target is locked, the collision time is calculated based on the image change, and an alarm is issued when the danger is considered.

The system connection diagram is as follows:

According to the historical data analysis of automobile accidents, 93% are artificial, especially due to negligence. The 3 seconds before the accident was the prime time to save. The anti-collision warning system is the technology for the driver to win this golden time.

In a long-term research trail with a customer who installed our products, we came to the following conclusions:

In general, the installation of the Aoten anti-collision warning system can effectively reduce and mitigate accidents and save lives! Hope that similar technologies can be rapidly popularized in China!
