Car door opening safety assisting device and method

Abstract

The invention provides a car door opening safety assisting device and method and belongs to the technical field of cars. The problems that operability of car door opening safety protection is too low and safety is not high in the prior art are solved. The car door opening safety assisting device comprises a car body controller, an ignition switch, a car speed sensor, a door lock switch, a door lock motor, a left radar sensor and a right radar sensor. The car speed sensor, the ignition switch, the left radar sensor, the right radar sensor and the door lock switch are connected with the input end of the car body controller. The door lock motor is connected with the output end of the car body controller. The method comprises the steps that A, whether a car is not stopped after being automatically locked or not is judged; B, whether objects approach to the rear portions of the left side and the right side of the car or not is judged; C, corresponding actions are conducted when the objects approach to the rear portions of the left side and the right side of the car; and D, corresponding actions are conducted when no object approaches to the rear portions of the left side and the right side of the car. The car door opening safety assisting device and method can improve the operability of car door opening safety protection and the safety when passengers open car doors and get off a car.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a door opening safety auxiliary device and method. Background technique [0002] At present, most vehicles have the function of automatic locking of the doors, that is, the doors will automatically lock after the vehicle reaches a certain speed. In the case that the vehicle is not turned off, if you want to open the door of the vehicle that is automatically locked and get off the vehicle, you need to send a signal to open the door lock through the door lock switch to control the corresponding door lock motor to open the corresponding door lock, and then open the door through the door handle. . [0003] With the development of society, there are more and more vehicles or other electric vehicles on the road, which makes the road appear very crowded. When people in the car get out of the car and open the door, if they do not pay much attention to the rear vehicle or other moving...

AI Technical Summary

Problems solved by technology

However, this system also has many shortcomings: the sensor is installed on the door handle, but the patent does not give specific instructions on how to set it up, and it is difficult to install the sensor on the door handle and the difficulty of debugging greatly increases the cost, and because the door handle often needs to use Therefore, the sensor is easily damaged and misoperation occurs; the system judges that the occupants get out of the car and locks all the doors when there is an object approaching, so that the door cannot be opened on the side where no object is approaching. After the door is opened, the camera can detect the door as an object approaching, so that other doors on the side cannot be opened

In summary, the operability of the door opening safety protection of this system is too low, the misoperation rate is too high, and the safety is not high
