Embodiment
The utility model is described in more detail below in conjunction with the accompanying drawings.
Embodiment 1
The active forewarning system of a kind of preventing collision provided by the utility model, as shown in Figure 1, including controller, thunder
Up to module and warning module, wherein, preferably controller is entire car controller.
Radar module is installed on the afterbody of vehicle, for example, rear bumper or back door centre position etc., ensure radar energy
It is enough effectively to gather front vehicle speed, spacing information, the speed collected and spacing information are sent to by CAN network whole
Vehicle controller.
Entire car controller signal connects radar module and warning module, and entire car controller receives the detection letter of radar module
Breath, judges speed, spacing, determines a need for alarming.Two kinds of anti-collision warning decision procedures are set, the first is sentenced
It is to send rear-end impact early warning by CAN network when the distance of detections of radar to front vehicle is less than setting value to determine mode；The
Two kinds of decision procedures are to send rear-end impact by CAN network when detections of radar to collision time is less than setting value to alarm, its
In, collision time is spacing and the ratio of opposite speed.
The vibrator for driving vibration of steering wheel is provided with warning module, vibrator can be installed on steering wheel,
When vibrator works, vibration of steering wheel is driven；Or vibrator is installed on the steering column of closure disk, when vibrator work
When making, steering column vibrations are driven, and by vibrations conduction to steering wheel, prompt driver to pay attention to front vehicle with this.
The workflow of the active forewarning system of a kind of preventing collision of the present embodiment 1, as shown in Fig. 2, idiographic flow
It is as follows：
1st, radar module works, detection front vehicle and the speed of the spacing of this car and this opposite car of detection.
2nd, entire car controller determines whether rear-end impact risk.
Two kinds of modes for judging rear-end impact risk：
First way, judges whether spacing is less than setting value；
The second way, judges whether collision time is less than setting value, and wherein collision time is spacing and opposite speed
Ratio.
3rd, when judging that spacing is less than setting value, or when judging that collision time is less than setting value, sent out by CAN network
Go out rear-end impact early warning control warning module.
4th, vibrator works, vibration of steering wheel are controlled, driver can experience vibrations when holding steering wheel, be prompted with this
Driver pays attention to front vehicle.
The present embodiment 1 carries out anti-collision warning analysis, and control vibrator to carry out by detections of radar by entire car controller
Alarm, completes the active forewarning of preventing collision.
Embodiment 2
Alarm mode in embodiment 1 can also merge more alarm modes, for example, add audible alarm pattern or
Add visual alert mode or add audible alarm pattern and visual alert mode at the same time, imitated with reaching preferably alarm
Fruit, therefore, the present embodiment 2 also provide a kind of active forewarning system of the more diversified preventing collision of alarm mode, as Fig. 3,
Shown in Fig. 4, alarm module is additionally provided with voice guard for making a sound alarm and for showing visual alarm signal
Visual alarm.Wherein, preferably voice guard is the buzzer alarmed for the sound that beeps, and visual alarm, example
Such as display, signal lamp etc., signal alarm is can be used as, preferably visual alarm is for showing setting signal alarm
Display.
Based on the workflow in embodiment 1, vehicle control unit controls control is further included during early warning
Buzzer and display.
Wherein, vehicle control unit controls buzzer siren beeps, for example, the time 5s of setting buzzer；Vehicle
Controller control display show that the printed words that such as " please note front vehicle " prompting driver pays attention to front vehicle.
Embodiment 3
Only early warning can be carried out to front truck driver before knocking into the back in above-described embodiment 1, embodiment 2, it is impossible to right
Rear car driver and surrounding vehicles driver are alerted, and therefore, the active that the present embodiment 3 provides another preventing collision is pre-
Alert system, as shown in Figure 5, Figure 6, on the basis of embodiment 2, visual alarm is further included to be carried out for light prompt surrounding vehicles
Left front lamp, right headlight, left tail lamp and the right tail lamp of alarm.
When entire car controller judge have rear-end impact risk when, entire car controller assign instruction control vehicle before, taillight
Into " double sudden strains of a muscle " pattern, before above-mentioned, four lantern festivals of tail uninterruptedly flicker, prompt rear driver and surrounding vehicles driver to pay attention to
Situation.
The embodiment that the utility model is related to is presented above, but the utility model is not limited to described reality
Apply mode.It is the judgement that vehicle rear-end collision collision is carried out by radar in the basic ideas of the utility model, and takes a variety of pre-
Alert prompting mode reminds vehicle driver, and definitive requirement is not done for specific control strategy, is not departing from this
The change, modification, replacement and modification carried out in the case of the principle and spirit of utility model to embodiment still fall within this practicality
In new protection domain.
