Problems solved by technology

According to statistics, a considerable proportion of automobile collision accidents occur at the moment when the occupants of the car open the door and get off after parking. During normal driving, I didn't realize that the door of the car parked next to me would be opened suddenly. At this time, it is very likely that the oncoming car will hit the suddenly opened door, or passers-by will be hit or knocked down by the suddenly opened door.

Embodiment 1

[0023] The car of this example, structure is identical with prior art, comprises front bumper, rear bumper, car door, compartment etc., and difference is that it has set up car door anti-collision warning system; Please refer to Fig. 1, the car door anti-collision of this example The early warning system includes a main control module, an ultrasonic transceiver module, a rear radar probe group, a power module, a contact sensor module, and an early warning signal execution module; The signal execution module and the ultrasonic transceiver module are respectively connected with the main control module. The power module transforms the 12V DC in the car to provide the working voltage of other modules of the system. The touch sensor module adopts four variable capacity sensors, which are respectively installed at the door handles in the car. The pre-warning signal execution module includes a buzzer, a voice module, and an electric control lock module; the output of the voice modul...

Embodiment 2

[0027] Please refer to Figure 2 and Figure 3, the car door anti-collision warning system of this example, on the basis of the previous example, add a group of radar probes, installed in the front safety gear of the car, can realize the anti-collision of the car ahead Early warning, further improving the active safety performance of the car.

Abstract

The vehicle and door anti bumping alarm method and system can realize detection for vehicles and people from behind, sending out hint or locking of the door, avoiding the sudden opening of the door to bump with the vehicle or people rushing from behind, with improved safety of vehicles. Using the existing reverse radar system, free from the influence of bumping alarm function, it realizes warning function of doors while alighting the cars, with small investment and low cost.

Description

【Technical field】 [0001] The invention relates to an automobile and its safety protection system. 【Background technique】 [0002] At present, the number of automobiles has increased significantly, and the environment for using automobiles has become increasingly complex. In order to prevent collisions when the car is reversing, current cars are generally equipped with a reversing radar, which is activated when the car enters the reverse gear to give an early warning to moving obstacles behind the car. This system effectively detects the distance of fixed moving obstacles or human bodies behind the car, avoiding collisions that may injure people or crash cars, which greatly facilitates drivers. But few people pay attention to the potential danger when the people in the car get off after parking. According to statistics, a considerable proportion of automobile collision accidents occur at the moment when the occupants of the car open the door and get off after parking. Duri...
