In view of the problems of the prior art, the present invention provides a pedestrian protection door, a control system, a method, a storage medium, a device and an application thereof, and the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, a pedestrian protection vehicle door according to an embodiment of the present invention includes: the piezoelectric actuator is composed of a piezoelectric actuator 3 based on an inverse piezoelectric effect material, a driving module 10, a controller 11 and a millimeter wave radar 12.
The controller 11 is connected with the millimeter wave radar 12 and the driving module 10 through a connecting line, and the driving module 10 is connected with the piezoelectric actuator 3 based on the inverse piezoelectric effect material through the connecting line.
Except that the piezoelectric actuator 3 and the driving module 10 thereof based on the inverse piezoelectric effect material are necessarily arranged between the elastic body and the shell of the vehicle door limiter, the millimeter wave radar sensor and the controller can be arranged at any position of the vehicle body, and the premise is to ensure that the millimeter wave radar sensor and the controller can work normally and do not influence the execution and the beauty of other mechanisms of the vehicle body.
The vehicle door limiter is provided with a shell 8, an elastic body 4, a roller 5, an arm 6 and a brake rubber block 7; the shell 8 is fixed on the vehicle door inner side plate 2 through bolts, two ends inside the shell 8 are respectively provided with an elastic body 4, the arm 6 penetrates through the middle of the shell 8, the upper side and the lower side of the arm inside the shell 8 are respectively provided with a roller 5, the brake rubber block 7 is fixed at the outer end of the arm 6, and the inner end of the arm 6 is connected with the vehicle body 1 through a pin 9. And a piezoelectric actuator 3 based on a reverse piezoelectric effect material is respectively clamped between the outer ends of the two elastic bodies 4 and the inner wall of the shell 8.
As shown in fig. 2, a control method for a pedestrian protection vehicle door according to an embodiment of the present invention includes:
s101, sensing information of pedestrians and vehicles in a specific area on the side face of a vehicle body by a millimeter wave radar arranged on the vehicle body, and transmitting signals to a controller;
s102, after the controller carries out receiving processing decision on the signals, the controller transmits the signals of whether to execute the piezoelectric actuator based on the inverse piezoelectric effect material to a driving module;
s103, when the driving module is not used for enabling, the piezoelectric actuator based on the inverse piezoelectric effect material keeps the length of the piezoelectric actuator perpendicular to the arm direction unchanged, the initial length of the elastic body keeps unchanged, and the vehicle door is in a state that the vehicle door can be opened under normal force;
s104, when the driving module is enabled, the piezoelectric actuator based on the inverse piezoelectric effect material is in a power supply triggering state, the length of the piezoelectric actuator perpendicular to the arm direction is increased, so that the length of the elastic body perpendicular to the arm direction is shortened, force acting on the roller is increased, difficulty of the roller moving to the arm is increased, force required by opening the vehicle door is increased, and the vehicle door is not easy to open.
The detection module is a millimeter wave radar 12 arranged on the side wall 1 of the vehicle body and is used for detecting the moving speed of pedestrians and non-motor vehicles in a specific area on the side surface of the vehicle body;
the single chip microcomputer control module is used for installing the inner side plate 2 of the car door and is used for processing signals and controlling the piezoelectric execution device;
the door stopper mechanism comprises a driving module arranged on the inner side plate 2 of the door and a piezoelectric actuator 3 based on an inverse piezoelectric effect material, and is used for increasing the door opening resistance of the door; in addition, the door check system includes an elastic body 4, a roller 5, an arm 6, a brake rubber 7, a housing 8, and a pin 9.
According to the embodiment of the invention, the piezoelectric actuator is designed at the position of the door stopper and is used for controlling the force of opening the door by a driver or a passenger, so that when a pedestrian or a vehicle tends to collide with the opened door on the side surface of the vehicle body, the thrust of opening the door is increased, and the situation that the driver or the passenger directly opens the door is avoided, so that the collision accident is avoided. The millimeter wave radar is used as a sensor to sense position and speed data of pedestrians and vehicles on the side face of the vehicle body, the data are transmitted to the controller to be subjected to decision processing, and the driving module of the piezoelectric actuator is controlled through an electric signal, so that the piezoelectric actuator is in a working or non-working state, and the opening force of the vehicle door is controlled. The positions and the speeds of pedestrians and non-motor vehicles in a specific area on the side face of the vehicle body are identified, the collected data are classified, decision is made according to the direction and the size of the target characteristic position and the speed, and a control signal is output to the piezoelectric actuator.
Compared with other pedestrian protection vehicle doors, the pedestrian protection vehicle door has the advantages of low cost, convenience in installation and no possibility of locking the vehicle door so as to respect the door opening intention of a driver or a passenger. The millimeter wave radar and the piezoelectric actuator adopting the inverse piezoelectric effect material are not high in price and high in stability. The existing door hinge structure is not changed during installation, and only the piezoelectric actuator is added to the elastic body part of the door hinge. Under the condition that the piezoelectric actuator is triggered to work, the difficulty of opening the vehicle door is increased, and the vehicle door is not locked. In this way, the driver or passenger can still open the door using normal and increased thrust.
If the driver and the passenger still have the requirement of opening the door, the thrust needs to be increased to open the door, and the value of the thrust is larger than that of the thrust for opening the door under the state that the piezoelectric actuator is not triggered.
