Abstract

The invention discloses an active anti-pinch method for an inner swing door of a passenger car, which is realized by adopting an anti-pinch mechanism, wherein the anti-pinch mechanism comprises a host and two cameras, the two cameras are respectively arranged in a front door and a middle door, the two cameras are arranged in an air duct at the top of the door, the host is arranged in the air duct, and the steps are as follows: after the camera detects a passenger, if the head of the passenger is in an anti-pinch dangerous area, the host outputs a 0V signal, and the host outputs a suspension signal when the head of the passenger is not in the anti-pinch dangerous area; the signal is given to the vehicle body module, if the danger signal appears when the door is static, the module does not respond to the door opening and closing operation of a driver, and if the danger signal appears in the door opening and closing process, the module controls the door to reversely act. The passenger car inner swing door active anti-pinch method can realize active anti-pinch of the inner swing door, has high sensitivity, can start anti-pinch before pinching a passenger, solves the problem that the passenger can restart the passenger by pinching the passenger, avoids discomfort of the passenger and claim of the passenger, and improves the product grade.

Description

Active anti-pinch method for inner swing door of passenger car

The technical field is as follows:

the invention relates to an active anti-pinch method for an inner swing door of a passenger car, and belongs to the technical field of passenger cars.

Background art:

the existing passenger car is basically prevented from being clamped by an anti-clamping module, a door is judged to be clamped by a person if the door is not closed in place at the specified time through limit switch or time calculation, and then the passenger car is started to prevent clamping. The existing passenger flow counting product is mature, and the head of a person can be accurately identified through image processing and algorithm and deep learning. However, these prior art techniques work when the door has caught the passenger, who still feels pain and may be claimed for use in an exit vehicle.

Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.

The invention content is as follows:

the invention provides an active anti-pinch method for a passenger car inner swing door, which aims to solve the problems in the prior art, can solve the problem that the existing inner swing door cannot actively prevent pinching, and can accurately identify the head of a person so as to give an anti-pinch alarm signal.

The technical scheme adopted by the invention is as follows: the utility model provides a passenger train inner swinging door initiative anti-pinch method, adopts and prevents that the clamp mechanism realizes, prevent that the clamp mechanism includes host computer and two cameras, two cameras are installed respectively in qianmen and zhongmen, and two cameras are installed in door top wind channel, and the host computer is arranged in the wind channel, and the step is as follows:

the method comprises the following steps: after the camera detects a passenger, if the head of the passenger is in an anti-pinch dangerous area, the host outputs a 0V signal, and the host outputs a suspension signal when the head of the passenger is not in the anti-pinch dangerous area;

step two: the signal is given to the vehicle body module, if the danger signal appears when the door is static, the module does not respond to the door opening and closing operation of a driver, and if the danger signal appears in the door opening and closing process, the module controls the door to reversely act.

Furthermore, the host computer provides the power of whole car and front door, well door switch status signal.

The invention has the following beneficial effects: the passenger car inner swing door active anti-pinch method can realize active anti-pinch of the inner swing door, has high sensitivity, can start anti-pinch before pinching a passenger, solves the problem that the passenger can restart the passenger by pinching the passenger, avoids discomfort of the passenger and claim of the passenger, and improves the product grade.

Description of the drawings:

FIG. 1 is a schematic view of an active anti-pinch mechanism of a swinging door in a passenger car.

The specific implementation mode is as follows:

the invention will be further described with reference to the accompanying drawings.

The active anti-pinch method of the inner swinging door of the passenger car is realized by adopting an anti-pinch mechanism, the anti-pinch mechanism comprises a host and two cameras, the two cameras are respectively arranged in a front door and a middle door, the two cameras are arranged in an air duct at the top of the door, and the host is arranged in the air duct. The main machine needs the whole vehicle to provide power and front door and middle door switch state signals.

The invention discloses an active anti-pinch method for a passenger car inner swing door, which comprises the following steps:

the method comprises the following steps: after the camera detects a passenger, if the head of the passenger is in an anti-pinch dangerous area, the host outputs a 0V signal, and the host outputs a suspension signal when the head of the passenger is not in the anti-pinch dangerous area;

step two: the signal is given to the vehicle body module, if the danger signal appears when the door is static, the module does not respond to the door opening and closing operation of a driver, and if the danger signal appears in the door opening and closing process, the module controls the door to reversely act.

The passenger car inner swing door active anti-pinch method can realize active anti-pinch of the inner swing door, has high sensitivity, can start anti-pinch before pinching a passenger, solves the problem that the passenger can restart the passenger by pinching the passenger, avoids discomfort of the passenger and claim of the passenger, and improves the product grade.

The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.

Claims (2)

1. The utility model provides a passenger train inner swing door initiative anti-pinch method, adopts and prevents that the clamp mechanism realizes, prevent that the clamp mechanism includes host computer and two cameras, two cameras are installed respectively in qianmen and zhongmen, and two cameras are installed in door top wind channel, and the host computer is arranged in the wind channel, its characterized in that: the method comprises the following steps:

the method comprises the following steps: after the camera detects a passenger, if the head of the passenger is in an anti-pinch dangerous area, the host outputs a 0V signal, and the host outputs a suspension signal when the head of the passenger is not in the anti-pinch dangerous area;

step two: the signal is given to the vehicle body module, if the danger signal appears when the door is static, the module does not respond to the door opening and closing operation of a driver, and if the danger signal appears in the door opening and closing process, the module controls the door to reversely act.
