Research On Early Warning Device Of Hidden Trouble In Automobile

Based on the research and analysis of three common safety hazards,the starting point’s the efficient use of existing resources,cost reduction and ease of dissemination.The corresponding solutions are proposed.To address the problem of safety hazards in the visual blind spot when the vehicle is driving on a curve.It is proposed to add rear-view lights to the body and control the turning on and off of the lights by the actual light or the driver’s will(hereinafter referred to as Device 1).To address the problem that the brake light does not provide brake intensity information in the existing automobile braking.It is proposed that by collecting brake deceleration and vehicle speed as danger signals,and quantifying the signals,the brake lights and rear horn are controlled with different Flashing frequency and varying horn volume(hereafter referred to as Device 2).This device addresses the problem that door openings can cause collisions with vehicles and pedestrians behind the vehicle.A time-delay control is used to remind passengers to observe the environment behind the vehicle when the door is opened(hereinafter referred to as Device 3).All three devices follow a unified technical line and are designed and implemented as follows.Each device includes signal acquisition module,control module and execution module.Device 1 in the photosensitive sensor signal acquisition and processing,through the implementation of the signal control rearview lights on and off;Device 2 Signal acquisition and processing of acceleration sensors and vehicle speed,and control of brake lights and rear horn in different ways during high braking hazards frequency flashes and sirens at different volumes;signal acquisition and circuit processing of the door handle position sensors in device 3,and the use of the door handle position sensor in the occupants’ Unlock the door after a delay to control the electronic door lock when the door is opened.On the basis of completing the hardware and software design,each device was tested and verified by simulation.
