Vehicle safety door opening reminding system based on vehicle body controller and control method of vehicle safety door opening reminding system

Abstract

The invention relates to a vehicle safety door opening reminding system based on a vehicle body controller and a control method of the vehicle safety door opening reminding system. A CAN bus is used for obtaining vehicle door lock state signals, whether a vehicle door is allowed to be opened or not is judged, and therefore whether the reminding function is activated or not is judged; an LED lamp installed at the in-vehicle handle position conducts vision reminding on a driver and passengers, and a buzzer arranged in an instrument conducts sound sensation reminding on the driver and passengers; and meanwhile, an out-vehicle width showing lamp or steering lamp is used for conducting vision reminding on back closing vehicles or conducting sound sensation reminding through a horn, the back closing vehicles are reminded of paying attention to parking vehicles on the front road face, and collision between the vehicle door and the back closing vehicles is accordingly avoided. According to the vehicle safety door opening reminding system and the control method, starting from door opening early alarming actual application scenarios, no radar sensor is adopted, the vehicle door opening reminding function can be achieved only by amending BCM controller software, and collision between the vehicle door and the back closing vehicles is avoided. Compared with a vehicle opening early alarming system at present, the vehicle safety door opening reminding system has the beneficial effects of being simple, practical, low in cost and the like.

Description

technical field [0001] The invention relates to vehicle active safety, in particular to a vehicle safety door opening reminder system based on a vehicle body controller and a control method thereof. Background technique [0002] Vehicle safety has been paid more and more attention by consumers, and active safety technology has played an increasingly prominent role in vehicle safety, not only in the protection of drivers and passengers, but also in the protection of people and non-motorized vehicles in the traffic environment. protection is also being strengthened. Wherein with vehicle door opening, the accident that vehicle door and rear approaching bicycle, motorcycle collide is particularly prominent. Fatal injury or even death to bicycle and motorcyclist drivers. Its reason is exactly because the driver and passengers do not pay attention to observe the vehicle condition at the rear when they open the door and get off the car and are eager to open the door, causing the ...

AI Technical Summary

Problems solved by technology

Both of the above two methods need to use sensors to detect the rear approaching targets, which need to increase the cost of sensors and system costs, and it is necessary to reserve sensor installation space in the vehicle warranty
