Embodiment Construction

[0032] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0033] The present invention is a driving assistance system that adopts 77GHz microwave radar technology to monitor the 30m blind area behind the vehicle, and the purpose is to give an alarm when the passenger or the driver opens the door and gets off the vehicle, and there is a danger of collision with the vehicle door when the vehicle coming from the opposite side and rear occurs. , Improve the safety of getting off with the door open. Specifically include:

[0034] A car door opening warning system, including a radar module, a system switch, a vehicle controller BCM, a reminder module, and a vehicle speed sensor. The radar module is arranged on the rear bumper for detecting rear vehicle data, and its output terminal is connected to the vehicle controller , the vehicle controller is resp...

Abstract

The invention discloses an automobile door opening early warning system and a method. The system involves a radar module, a system switch, a vehicle control unit BCM, a reminding module and a vehiclespeed sensor, wherein the radar module is arranged on a rear bumper and is used for detecting the data of a rear vehicle, the output end of the radar module is connected with the vehicle control unit,and the vehicle control unit is connected with the system switch, the vehicle speed sensor and the reminding module. The system and the method have the advantages that the rear vehicle is detected through radar, and then a reminder is given out to reduce the risk of an accident caused by door opening collision; whether the reminder is given out or not is judged by further calculating the collision time of the rear vehicle, so that the judgment is more reasonable, and traffic accidents caused by collision can be effectively reduced; and meanwhile, when the door is still opened after the earlywarning reminder is given out, the door opening intention is detected, the door is locked, the door at the side is prevented from being opened, so that the risk of door opening collision is effectively avoided, and the safety is further ensured.

Description

technical field [0001] The invention relates to the field of automobile electric appliance control, in particular to an automobile door opening safety early warning system and method. Background technique [0002] After the vehicle is parked, when the driver or passenger opens the door and gets off the vehicle, it is impossible to judge whether the vehicle (commonly battery cars, motorcycles and automobiles) traveling in the left or right rear blind spot will collide with the door, and "door opening" often occurs. kill". Existing vehicles basically have no special solution to this, mainly relying on the driver to remind the passengers, especially the rear passengers, to see the surrounding vehicles clearly, and only open the door to get off after confirming safety, otherwise accidents will occur. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a car door opening warning system and method...
