Embodiment 1

[0017] like figure 1 As shown, the system for preventing accidental door collision in this embodiment is composed of a vehicle speed signal acquisition unit, a vehicle body controller, a door lock state control unit, an interior warning unit, and an exterior warning unit. The signal acquisition unit, the door lock state control unit, the warning unit inside the vehicle, and the warning unit outside the vehicle are connected.

[0018] In this embodiment, the warning unit inside the car is a combination meter of the car, and the warning unit outside the car is a warning light of the car, so as to make full use of existing devices and reduce costs.

[0019] The control method of the above-mentioned system for preventing the accidental door from colliding is as follows:

[0020] like figure 2 As shown, after the car is ignited, the body controller will automatically lock the door through the door lock state control unit when the speed of the car is higher than the predetermined...

Embodiment 2

[0023] The control method of the system for preventing accidental door collision in this embodiment is different from Embodiment 1, as image 3 As shown, in this embodiment, after the car is ignited, the body controller will automatically lock the door through the door lock state control unit when the vehicle speed is higher than the predetermined speed (10Km / h); when the vehicle speed drops to zero, After receiving the door lock opening control signal, the vehicle body controller first utilizes the warning unit inside the car and the warning unit outside the car to remind, and then opens the car lock through the door lock state control unit.

Abstract

The invention aims at providing a system for preventing collision caused by incorrect vehicle door opening and a control method thereof. According to the invention, the system for preventing collision caused by incorrect vehicle door opening comprises a vehicle speed signal collecting unit, a vehicle body controller, a door lock state control unit, an interior warning unit and an exterior warning unit, wherein the vehicle body controller is respectively connected with the vehicle speed signal collecting unit, the door lock state control unit, the interior warning unit and the exterior warning unit. When the vehicle body controller automatically locks a vehicle door through the door lock state control unit when a vehicle speed is higher than a preset vehicle speed; and after the speed of an automobile is lowered to zero, the vehicle body controller respectively prompts through the interior warning unit and the exterior warning unit after a door lock is unlocked. According to the invention, the system for preventing collision caused by incorrect vehicle door opening can be realized only by changing software on the basis of the original hardware module of the whole automobile; therefore, the system for preventing collision caused by incorrect vehicle door opening has the advantages of low cost, comparatively simple and reliable function logic and very good practicability and can effectively remind people in the automobile of confirming before opening the door.

Description

technical field [0001] The invention belongs to the technical field of automobile control systems, and in particular relates to a system and a control method for preventing accidental door opening from colliding. Background technique [0002] With the development of the economy, the number of cars is increasing, but some drivers and passengers lack safety awareness, and forget to check whether there are pedestrians and vehicles around the vehicle after parking. In this case, opening the door may often bring traffic ACCIDENT. [0003] In response to the above situation, the current common solution is to monitor the surrounding vehicles and pedestrians in real time through various sensors (such as cameras, radars, etc.) and give alarm reminders. For example, the invention patent whose patent number is CN201310206131.0 discloses a vehicle door opening warning system and an alarm method of the warning system, including: an information collection unit for real-time detection of ...
