Through system self-checking, guarantee the correct operation of door anticollision early warning mode, avoid the unexpected situation that leads to because of the fault to take place, provide good driving experience for the user.
Step S203: and when the self-checking result of the system meets the opening requirement, judging whether the current vehicle speed is 0km/h, if the current vehicle speed is not 0km/h, closing the system, and not executing the vehicle door anti-collision early warning mode. Specifically, the system receives the vehicle speed state in real time, if the vehicle speed is 0km/h, the system judges that a driver and a passenger in the vehicle have the possibility of opening the vehicle door, and the system monitors a certain area range behind a left rear-view mirror and a right rear-view mirror of the vehicle and right rear of the vehicle in real time through a radar module; if the vehicle speed is not 0km/h, the system judges that the driver and the passengers in the vehicle do not have the possibility of opening the vehicle door, and the door opening anti-collision early warning mode is closed. Through the judgement to the speed of a motor vehicle, and then judge whether current vehicle need carry out door anticollision early warning, not only can practice thrift partial power consumption, can also avoid in the car driver and crew to be disturbed by unnecessary early warning, and then improve user's driving and experience.
Step S204: and when the vehicle speed is 0km/h, monitoring the areas behind the left and right rearview mirrors of the vehicle and right behind the vehicle in real time. The method comprises the steps of monitoring moving targets behind left and right rearview mirrors of a vehicle and in an area right behind the vehicle through a radar, wherein the monitoring content comprises the distance, the displacement direction and the displacement speed of the targets. The system calculates through data monitored by the radar, confirms the early warning area and matches the corresponding TTC threshold value. Through monitoring the displacement speed and the distance of the moving target, the corresponding TTC is calculated, and the corresponding TTC threshold value is formed, so that the universality and pertinence of the anti-collision early warning are increased, and the early warning effect of the anti-collision early warning is improved.
Step S205: when the moving target exists in the area behind the left and right rearview mirrors of the vehicle and the area right behind the vehicle, whether the target triggers the TTC threshold value or not is monitored, and if not, the step S204 is repeated.
Step S206: and when the moving target triggers the early warning TTC threshold value, judging whether the door lock is unlocked, if the door lock is unlocked, triggering three-stage early warning, and when the driver and passengers stop the door opening action according to the early warning and the moving target leaves the early warning area, ending timing of the system, releasing the early warning, and resuming the detection of the next target. Specifically, the system monitors that a moving target in an area range meets a door opening collision condition (TTC is less than or equal to a TTC threshold value) through a radar module, and when a vehicle door lock is in an open state, the system sends out a three-level early warning. The three-stage early warning state is as follows: the reminding lamp of the door handle of the related vehicle door flashes (high frequency), the vehicle instrument sends out alarm sound (high frequency), the instrument displays corresponding characters for reminding, the outline marker lamp outside the vehicle is turned on, the left and right direction lamps outside the vehicle flash (high frequency), and the anti-theft alarm sound of the vehicle is triggered.
Step S207: and when the door lock of the vehicle door is not unlocked, judging whether the door handle has displacement, if so, triggering secondary early warning, and when the driver and passengers stop the door opening action and the moving target leaves the early warning area, ending timing of the system, releasing the early warning, and resuming the detection of the next target. Specifically, the system monitors that a moving target in an area range meets a door opening collision condition (TTC is less than or equal to a TTC threshold value), a vehicle door lock is in an unopened state, and when a vehicle door handle displaces through a radar module, the system sends out secondary early warning. The secondary early warning state is as follows: the reminding lamp of the door handle of the related vehicle door flashes, the vehicle instrument gives an alarm sound, the instrument displays corresponding characters for reminding, the outline marker lamp outside the vehicle is turned on, and the left and right direction lamps outside the vehicle flash.
Step S208: when the door lock of the car door is not unlocked and the door handle does not displace, primary early warning is triggered, when the moving target leaves an early warning area, timing of the system is ended, early warning is released, and detection of the next target is resumed. Specifically, when the system monitors that a moving target in an area range meets the door opening collision condition, a vehicle door lock is in an unopened state, and a vehicle door handle is not displaced through a radar module, the system sends out primary early warning. The first-level early warning state is as follows: the reminding lamp of the door handle of the related vehicle door is normally on, the instrument displays corresponding characters for reminding, and the outline marker lamp outside the vehicle is turned on. Wherein, table 1 is the layering early warning table of the anti-collision early warning system that opens the door of car.
