Vehicle door control system, method and device and vehicle body controller

Abstract

The invention relates to a vehicle door control system, method and device and a vehicle body controller. The vehicle door control system comprises the vehicle body controller, a blind area detection device, a door opening intention detection device, a vehicle speed detection device and an in-vehicle lock control device. The vehicle speed detection device is used for transmitting the detected current speed value of a vehicle to the vehicle body controller, the vehicle body controller is used for activating a safe door opening auxiliary function of the vehicle when the current speed value is smaller than a preset vehicle speed threshold value, wherein the preset vehicle speed threshold value is larger than zero, and the blind area detection device is used for detecting the collision risk ofa detection area corresponding to the door of the vehicle when the safety door opening auxiliary function is activated, and transmitting the detected collision risk parameter to the vehicle body controller. By adopting the vehicle door control system, the collision risk and the door opening intention can be detected in advance before the vehicle is parked, so that the waiting time for people in the vehicle to judge whether the door can be opened is shortened, and the efficiency is higher.

Description

Technical field [0001] This application relates to the field of automobile technology, and in particular to a vehicle door control system, method, device, and body controller. Background technique [0002] With the growth of the economic level, the number of cars has increased year by year, and the safety of vehicles has attracted more and more attention from users. In recent years, drivers or passengers have not noticed the situation behind the door when opening the door, resulting in frequent collisions between the door and other vehicles or pedestrians behind the door when opening the door, causing safety accidents. [0003] Therefore, the vehicle is generally equipped with a door alarm device. However, the existing door alarm device usually detects the situation behind the door through detection devices such as radar after the car is parked to determine whether the door can be opened, which takes a long time. In other words, after parking, the people in the car still need to w...

Problems solved by technology

In recent years, the driver or passenger did not pay attention to the situation behind the door when opening the door, which led to frequent collisions between the door and other vehicles or pedestrians behind when the door was opened, resulting in safety accidents

[0003] Therefore, the vehicle is generally provided with an alarm device for opening the door. However, the existing alarm device for opening the door usually detects the situation behind the door through a detection device such as a radar after the car is parked, and judges whether the door can be opened, which takes a long time. That is to say, after parking, the occupants of the car still need to wait for a period of time to know whether the door can be opened, which has a certain delay and is inefficient
