[0037] A system and method for safely opening a vehicle door after parking of the present invention are described in detail below.

[0038] The present invention provides a system for safely opening a car door after parking, comprising a control module 1, a sensor module 2, an atmosphere light module 3, an alarm module 4, a door opening intention detection module 5 and an electronic door lock 6, wherein the control module 1 adopts a body domain controller, which is used to calculate the moving speed of vehicles and personnel according to the moving information of vehicles and personnel around the car collected by the sensor module 2. When the moving speed of the vehicle or personnel exceeds the set speed, the control module 1 issues a prompt through the atmosphere light module 3 and issues an alarm sound through the alarm module 4 to prompt the user. The control module 1 receives the user's door opening intention information collected by the door opening intention sensor, and locks the electronic door lock 6 when the moving speed of the vehicle or personnel exceeds the set speed. In the embodiment of the present invention, the set speed is 10KM / h, and the body domain controller adopts the Jingwei Hirain commercial vehicle body domain controller BDCU.

[0039] The sensor module 2 uses an ultrasonic sensor to determine the position and distance of vehicles or people around the car, and transmits the position and distance information of vehicles or people around the car to the control module 1. The control module 1 receives the position and distance information of vehicles or people around the car transmitted in real time by the sensor module 2, and calculates the moving speed of vehicles or people around the car according to the time difference of the information acquisition input of the ultrasonic sensor.

[0040] The atmosphere light module 3 uses a door atmosphere light, which is used to give a prompt when the speed of vehicles or people around the car exceeds the set speed. Specifically, the atmosphere light module 3 emits red light and flashes. The door atmosphere lights are set on the left and right sides of the car. When the speed of vehicles or people around the car exceeds the set speed, the door atmosphere light on the corresponding side of the vehicle or person emits red light and flashes.

[0041] The alarm module 4 uses a door speaker to sound an alarm when the speed of vehicles or people around the car exceeds a set speed. Specifically, the door speaker emits a "beep, beep, beep" alarm sound. The door speakers are arranged on the left and right sides of the car. When the speed of vehicles or people around the car exceeds the set speed, the door speaker on the corresponding side of the vehicle or person emits a "beep, beep, beep" alarm sound.

[0042] The ambient light module 3 and the alarm module 4 of the present invention are used in combination, and can also remind the user when one of them fails, and the two reminder means can serve as reminders for users with poor hearing or poor eyesight, thereby improving the user experience.

[0043] The door opening intention detection module 5 uses an interior door handle sensor to detect the user's door opening intention and transmit the user's door opening intention information to the control module 1. In the embodiment of the present invention, the interior door handle sensor uses capacitive sensing technology. When a human body approaches, the capacitance of the interior door handle sensor will change, and the interior door handle sensor will input the capacitance change signal to the control module 1. Each door handle of the car is equipped with an interior door handle sensor.

[0044] The electronic door lock 6 is used to lock the door when vehicles or people around the car approach quickly and when the user intends to open the door, so as to protect the personal and property safety of the user.

[0045] The output end of the ultrasonic sensor is connected to the input end of the body domain controller, the output end of the body domain controller is connected to the input end of the door atmosphere light, the output end of the body domain controller is connected to the input end of the door speaker, the output end of the interior door handle sensor is connected to the input end of the body domain controller, and the output end of the body domain controller is connected to the input end of the electronic door lock 6.

[0046] A method for safely opening a vehicle door after parking is provided by the present invention:

[0047] When the vehicle speed is zero and the vehicle is in the parking gear, the ultrasonic sensor detects the movement information of vehicles and people around the vehicle and transmits it to the control module 1. Specifically, the control module 1 obtains the vehicle speed and gear information input by the vehicle speed sensor and the gear sensor through the vehicle CAN network, and receives the vehicle and personnel movement information around the vehicle input by the ultrasonic sensor in real time.

[0048] The control module 1 calculates the moving speed of vehicles and people around the car. When the moving speed of vehicles or people around the car exceeds the set speed, the control module 1 controls the ambient light module 3 to issue a prompt, and controls the alarm module 4 to issue an alarm. Specifically, the control module 1 calculates the moving speed of the vehicle or person in real time based on the moving information of the vehicle or person around the car input by the ultrasonic sensor. When the moving speed of the vehicle or person exceeds the set speed, that is, exceeds 10KM / h, the control module 1 outputs a control instruction to the ambient light module 3 and the alarm module 4 according to the position of the vehicle or person to issue a prompt. Specifically, when there are cars or people moving on the left and right sides of the car and the moving speed exceeds the set speed, the control module 1 controls the atmosphere light modules 3 on the left and right sides of the car to issue a prompt, and controls the alarm module 4 to issue an alarm; when there are cars or people moving only on the left side of the car and the moving speed exceeds the set speed, the control module 1 controls the atmosphere light module 3 on the left side of the car to issue a prompt, and controls the alarm module 4 to issue an alarm; when there are cars or people moving only on the right side of the car and the moving speed exceeds the set speed, the control module 1 controls the atmosphere light module 3 on the right side of the car to issue a prompt, and controls the alarm module 4 to issue an alarm.

[0049] Under the premise that there are vehicles or people approaching quickly around the above-mentioned car, after the door opening intention detection module 5 detects that the user has the intention to open the door, the door opening intention detection module 5 transmits the user's door opening intention information to the control module 1, and the control module 1 controls the electronic door lock 6 of the door corresponding to the door opening intention sensor to lock. Taking the embodiment as an example, when a vehicle or person approaches quickly on the right side of the car, the user is ready to open the door through the door handle of the right door. At this time, the interior door handle sensor of the right door detects the user's intention to open the door and transmits the information to the control module 1, and the control module 1 outputs a control instruction to control the electronic door lock 6 of the right door to lock.

[0050] When the safe exit system of the present invention erroneously determines that a vehicle or person is passing by the vehicle and the door cannot be opened, the user can release the locking instruction of the control module 1 to the electronic door lock 6 by opening the door handle inside the vehicle three times in a row. The present invention adds remedial measures in case of system failure while taking into account the safe exit of the user, thereby improving the safety of the present invention.

[0051] The present invention can reduce or avoid the occurrence of "door opening kill" when opening the door when parking, effectively protecting the personal and property safety of users.

[0052] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
