When this car stops, and door lock be in allow opening time, system alarm function is opened, if the moving target now having speed to be greater than 5km/h enters rear alarm region, then system carries out visual alerts by LED Warning light 81 couples of driver and crew of alarm set in car 8, reminds driver and crew will note later observation rear vehicle condition; Simultaneously by the outer side-marker lamp 91 of car of outer warning device 9 correspondence of car, steering indicating light 92 pairs of rear approaching vehicle carry out visual alerts, and carry out sound sensation prompting by loudspeaker 93 pairs of rear approaching vehicle, remind rear approaching vehicle to note dodging.When driver and crew prepare to get off for opening car door, when stirring the moment of the door contact interrupter signal that grip handle triggering door contact interrupter 5 exports, control unit is crossed and is controlled the instrument of warning device 8 correspondence is built-in in car buzzer phone 82 or phonetic alarm device 83 couples of driver and crew remind further, remind driver and crew will note later observation rear vehicle condition, car door is opened in segmentation, opens car door when guaranteeing safe.
When by the vehicle speed pulse detecting car speed sensor 3 output, control unit 1 judges that vehicle is in running state, prompting function is closed automatically.When control unit 1 is by detecting that automobile door lock status switch 4 on-off signal judges that door lock is in closed condition, prompting function is closed automatically.
By the on-off signal detecting engine ignition switch 2 output, control unit 1 judges that vehicle is in igniting or flameout state.After vehicle is flame-out, and when door switch is in closed condition, system is judged as that driver and crew have got off and leaves, and after the time of delay adjustments, system shutdown own power source, system is closed automatically.
When car door door lock 4 unblock next time, the high level on-off signal of output controls system power supply to connect, and system re-powers operation.After system electrification, power supply is connected by the control signal exported by system simultaneously, and when ensureing that car door door lock 4 is in closed condition, during output low level on-off signal, system power supply is powered normally.
Above exemplifying embodiment is example 2: based on the mode adopting wire harness mutual with car load, for this car vehicle by most right lane, and by the situation stopped in the rightmost side in track, adopt single Doppler Lidar System only to detect vehicle right and left and dead aft alarm region, cost is lower.
Embodiment 3, as shown in Figure 5, after vehicle, protect both sides respectively two Doppler radars are installed, for detecting the left and right rear of vehicle and dead aft alarm region, then this car stops not by above restriction, be not limited to by most right lane, and by the situation stopped in the rightmost side in track, but system cost doubles.
For the radar sensor of rear alarm region moving object detection, be not limited to Doppler radar, adopt the enabling forewarn system of other radar detection apparatus or sensor device to belong to this patent protection domain equally.
The control method of this enabling forewarn system, comprises the steps:
Door lock for vehicle unlocks, and the high level on-off signal of output controls system power supply to connect, and system re-powers operation;
According to car speed, control unit judges whether vehicle is in halted state, if vehicle is in running state, system alarm provides closedown, if vehicle is in halted state, carries out step below;
If car door door lock is in opening, then warning function is opened, otherwise warning function is closed;
If car door door lock is in opening, then whether control unit has moving target close by the sensor detection rear alarm region in protecting after being arranged on vehicle, if there is moving target to enter alarm region, then carries out step below;
If car door opening, the vision inside and outside opening vehicle and sound sensation alarm set are reminded; If car door is not opened, then the visual alerts device inside and outside an opening vehicle is reminded;
By engine ignition state, control unit judges that vehicle is in igniting or flameout state.After vehicle is flame-out, and when door switch is in closed condition, system is judged as that driver and crew have got off and leaves, and after the time of delay adjustments, system shutdown own power source, system is closed automatically.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present utility model and technical scheme are carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
