Specific embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein ad initio
Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng
The embodiment for examining Description of Drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
Below with reference to the accompanying drawings describe the utility model embodiment for the driver fatigue monitor system of vehicle and with it
Vehicle.
Fig. 1 is that the square frame of the driver fatigue monitor system for vehicle according to the utility model one embodiment is illustrated
Figure.As shown in figure 1, the driver fatigue monitor system includes：Early warning switch 10, electronic control unit 20, the inspection of timer 30, pedal
Survey unit 40 and alarm unit 50.
Wherein, early warning switch 10, timer 30, pedal detection unit 40 and alarm unit 50 respectively with electronic control unit
20 are connected.The control vehicle of electronic control unit 20 enters fatigue driving modes of warning, timer 30 after early warning switch 10 is triggered
Start timing in engine start, and if pedal detection unit detection 40 is arrived without pedal action in the first Preset Time,
Timer 30 is reset, and electronic control unit 20 is controlled when the accumulative timing time of timer 30 reaches the second Preset Time
Alarm unit 50 sends fatigue driving prompt messages.Wherein, the first Preset Time can be 20min, the second Preset Time
Can be 240min.
According to one embodiment of the present utility model, early warning switch 10 can switch for locking type or can be homing position type
Switch.
Specifically, user can switch the 10 autonomous fatigues for being turned on or off vehicle and drive according to actual conditions by early warning
Warning function is sailed, if the indicator lamp on early warning switch 10 is bright, shows that fatigue driving warning function is opened, vehicle is driven into fatigue
Sail modes of warning；If the indicator lamp on early warning switch 10 extinguishes, show that fatigue driving warning function is closed.
For example, after user's triggering early warning switch 10, it is pre- that the control vehicle of electronic control unit 20 enters fatigue driving
Alert pattern, as shown in Fig. 2 when electronic control unit 20 monitors the engine start of vehicle, i.e., when engine car, if
Speed is more than 0, then the control of electronic control unit 20 timer 30 starts timing, and accumulative timing time in timer 30 reaches
During 240min, i.e., at 4 hours, illustrate that driver continuously drives 4 hours, then the control of electronic control unit 20 alarm unit 50 is sent out
Go out fatigue driving prompt messages.If speed is equal to 0, whether driver is judged at seat, if it is determined that driver is not
At seat, then control timer 30 not-time；If driver starts in seat, the control timer 30 of electronic control unit 20
Timing, if pedal detection unit 40 detects vehicle without pedal action in 20min, illustrates that driver is not driven a vehicle
Operation, for example, driver may rest in the car, then timer 30 resets, and re-starts timing；If in 20min, stepped on
Plate detection unit 40 has detected pedal and has acted, then timer 30 continues timing, and accumulative timing time in timer 30 reaches
During to 240min, i.e., 4 hour, illustrate that driver continuously drives 4 hours, then the control of electronic control unit 20 alarm unit 50 is sent out
Go out fatigue driving prompt messages, to remind driver to be rested, so as to improve the security of driving.
Wherein it is possible to pass through to detect that whether the vehicle door status of driver side and seat belt status judge driver at seat,
When the closing of the door and safety belt of driver side are fastened, illustrate driver at seat.Can also be by the seat of driver
Whether install pressure sensor judges driver at seat.
Because the electronic control unit of vehicle is normal electricity, so timer 30 starts (Key-on) in the key module of vehicle
Or can be carried out timing when closing (Key-off).When electronic control unit 20 monitors that key module is closed, that is, drive
When member stops driving vehicle, timer 30 resets and restarts timing, and is zeroed after 20min is reached in timing time.
And when working as key module startup (Key-on), as shown in figure 3, when the fatigue driving warning function of vehicle is opened,
If the timing time of timer 30 is zero, electronic control unit 20 allows engine start；If the timing of timer 30
Time is not zero, and illustrates driver's time of having a rest less than 20min, and to improve traffic safety, electronic control unit 20 is forbidden starting
Machine starts, and controls alarm unit 50 to send fatigue driving prompt messages to remind driver to be rested.Driver can
To continue waiting for, until when the timing time of timer 30 reaches 20min, electronic control unit 20 allows engine start.And
If because special circumstances are not desired to the rest that waits or stop, driver can switch 10 closing fatigues and drive driver by early warning
Warning function is sailed, now, electronic control unit 20 allows engine start.
It should be noted that no matter under what circumstances, the 10 fatigue driving early warning work(for closing vehicle are switched by early warning
During energy, timer 30 can reset.
According to one embodiment of the present utility model, early warning switch 10 can be by rigid line and the phase of electronic control unit 20
Connect, or, early warning switch 10 carries out CAN communication with electronic control unit 20.
According to one embodiment of the present utility model, pedal detection unit 40 corresponds to brake pedal and/or the acceleration of vehicle
Pedal is set.
Specifically, pedal detection unit 40 is acted by detecting brake pedal or accelerator pedal whether there is pedal, or simultaneously
Detection brake pedal and accelerator pedal whether there is pedal action, to judge whether driver has moving operation.
According to one embodiment of the present utility model, alarm unit 50 includes fatigue driving early warning indicator lamp, fatigue driving
Early warning indicator lamp is arranged in the instrument of vehicle.
When the fatigue driving warning function of vehicle is opened, if the continuous driving time of driver reaches 4 hours, vehicle
Instrument board in the flicker of fatigue driving early warning indicator lamp, or while fatigue driving early warning indicator lamp flashes, electronics control
Unit processed 20 controls buzzer warning, to remind driver to be rested.Wherein, fatigue driving early warning indicator lamp can be with coffee
The pattern displaying of cup out, is not specifically limited herein.
It is appreciated that when the fatigue driving early warning indicator lamp in instrument board flashes, expression does not currently allow engine to open
It is dynamic；When the fatigue driving early warning indicator lamp in instrument board extinguishes, representing current allows engine start.In the fatigue of vehicle
When driving warning function closing, the fatigue driving early warning indicator lamp in indicator lamp and instrument board on early warning switch 10 extinguishes.
In sum, according to the driver fatigue monitor system for vehicle of the present utility model, after early warning switch is triggered
Electronic control unit control vehicle enters fatigue driving modes of warning, and timer starts timing in engine start, and the
If pedal detection unit is detected without pedal action in a Preset Time, timer resets, and in the accumulative meter of timer
When the time when reaching the second Preset Time electronic control unit control alarm unit send fatigue driving prompt messages, to carry
Awake driver is rested, so as to improve the security of driving.
Additionally, the utility model also proposed a kind of vehicle, it includes the above-mentioned fatigue driving early warning system for vehicle
System.
Vehicle of the present utility model, by the above-mentioned driver fatigue monitor system for vehicle, is touched in early warning switch
Electronic control unit control vehicle enters fatigue driving modes of warning after hair, and timer starts timing in engine start, and
If pedal detection unit is detected without pedal action in the first Preset Time, timer resets, and in the tired of timer
Electronic control unit control alarm unit sends fatigue driving prompt messages when meter timing time reaches the second Preset Time,
To remind driver to be rested, so as to improve the security of driving.
