Embodiment
With reference to the accompanying drawings and examples to lane deviation alarm device in a kind of vehicle travel process of the present utility model
It is described in further detail.
The utility model protection be system in itself, the main annexation protected between hardware and hardware.
As shown in Figure 1, 2, lane deviation alarm device in a kind of vehicle travel process, camera unit 1 are arranged on vehicle
Rear and front end, and the camera lens of the camera unit 1 is towards the headstock and the tailstock of the vehicle, the shooting of vehicle rear and front end
Head unit 1 is responsible for the lane boundary signal of collection vehicle rear and front end.
Dtc signal detection unit 2 is arranged on the drive link of steering wheel for vehicle, and in the present embodiment, dtc signal detection is single
Member 2 is torque sensor, torque sensor gathers the dtc signal of steering wheel, is responsible for whether detection driver is actively controlled successively
Vehicle processed.
Whether steering indicating light detecting signal unit 3 is connected with the steering indicating light control terminal of vehicle, be responsible for detecting driver and opening turning
To lamp, specifically, steering indicating light detecting signal unit 3 collects the control signal of steering indicating light, judge vehicle whether open to the left or
Steering indicating light to the right.
Brake signal detection unit 4 is connected in vehicle brake control terminal, is responsible for whether detection driver is braked.
The signal input part of control unit 6 respectively with camera unit 1, dtc signal detection unit 2, steering indicating light signal detection
Unit 3 connects with the signal output part of brake signal detection unit 4, and control unit 6 is responsible for the signal that processing collects, and will handle
Object information afterwards is sent to alarm unit 7, and alarm unit 7 performs different operations according to the unlike signal sent.
Alarm unit 7 is connected with described control unit 6, and voice prompting device, control unit are provided with the alarm unit 7
6 are responsible for the signal that processing collects and send signal to alarm unit 7, and alarm unit 7 is responsible for sending alarm in deviation
Signal.
If the dtc signal that camera signals or dtc signal detection unit 2 that camera unit 1 collects collect
In appoint have signal show vehicle deviate it is normal carry out path after, control unit 6 detects steering indicating light detecting signal unit 3 and gathered
Turn signal modulating signal, if driver actively opens turn signal, then it represents that vehicle belongs under normal driving pattern,
Alarm unit is failure to actuate.If deviation is detected, while control unit does not detect any turn signal, then control is reported
Alert unit action, prompts driver vehicle to be in deviation state, to avoid driver from operating caused change under automatism
Road.
In the case where vehicle is in deviation state, if brake signal detection unit 4 detects that driver is actively made
Dynamic, then alarm unit can release alarm mode.
In above-mentioned technical proposal, warning device also includes camera signals processing unit 5, in the present embodiment, the shooting
The head core of signal processing unit 5 is FPGA module.The camera unit 1 is connected by the camera signals processing unit 5
To the signal input part of described control unit 6, it is single that the image information that camera unit 1 collects is sent to camera signals processing
Image recognition is carried out in member 5, identifies lane boundary signal, so as to which control unit 6 judges vehicle according to lane boundary signal
Whether normally travel track is deviateed.
In above-mentioned technical proposal, the camera unit 1 is high-definition camera, with the lane boundary before and after this collection vehicle
Information, improve recognition correct rate.Moveable filter is provided with the camera lens of the high-definition camera, meanwhile, the high definition is taken the photograph
