Embodiment 1

[0029] as attached Figure 1-3 As shown, the radar-based door safety opening system includes a radar, a door lock a and an actuator. When the door is closed, the door lock a locks the door; the radar is installed at the rear of the vehicle and detects the rear of the vehicle when it is working. When an approaching vehicle is found, the actuator is notified to open the door lock a. The actuator is an essential and important part of the automatic control system. Its function is to accept the control signal sent by the controller, change the size of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. According to its energy form, actuators can be divided into three categories: pneumatic, hydraulic and electric; according to different control functions, they can be divided into position control type (such as valve opening control), division control type (such as pump speed control) and Electric power control type (suc...

Embodiment 2

[0035] as attached Figure 4-7 As shown, the radar-based door safety opening system includes a radar, a door lock a and an actuator. When the door is closed, the door lock a locks the door; the radar is installed at the rear of the vehicle and detects the rear of the vehicle when it is working. When an approaching vehicle is found, the actuator is notified to open the door lock a.

[0036] It also includes an on-board power supply, which supplies power to the radar and actuators.

[0037] It also includes the door lock b controlled by the inner door handle that is standard on the vehicle.

[0038] The radars are distributed left and right on the vehicle, respectively controlling the opening of the left and right door locks a.

[0039] It also includes a vehicle speed sensor. When the vehicle speed drops to zero, the vehicle speed sensor sends a signal to the radar, and the radar starts to work.

[0040] It also includes a touch switch, which is installed on the surface of t...

Abstract

The invention aims to solve the problem of how to prevent door opening from being killed when a vehicle door is opened. A vehicle door safety opening system based on a radar comprises the radar, a door lock a and an actuator, and when the vehicle door is closed, the door lock a locks the vehicle door; and the radar is installed behind a vehicle, detects the rear portion of the vehicle during working, and notifies the actuator to open the door lock a only when the approaching vehicle is not found. The system has the beneficial effects that the door lock a cannot be opened when the radar finds an approaching vehicle, so that door opening killing is effectively prevented; and the actuator can reliably control the door lock a to be opened, and a touch door lock can prevent the door from being quickly opened and can ensure that a vehicle door opening signal can be timely and effectively sent out. In addition, during unmanned driving, a driver cannot supervise passengers to slowly open the door to get off, and the system is more useful at the moment.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a radar-based vehicle door safety opening system. Background technique [0002] Door opening killing means that when passengers get off and open the door, the motorcycle behind is likely to hit the door and cause an accident, which is a behavior that seriously endangers traffic safety. The reason is that some passengers do not pay attention to the situation behind when they open the door. The sudden opening of the door may easily cause the rear car and motorcycle to react untimely and fail to avoid. Contents of the invention [0003] During the problem to be solved by the present invention, how to avoid opening the door to kill when opening the door. [0004] Radar-based door safety opening system, including radar, door lock a and actuator, when the door is closed, the door lock a locks the door; the radar is installed at the rear of the vehicle, and detects the rear of the v...
