Fig. 1 is the structural representation of one embodiment of traffic safety phone system provided by the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
It is the structural representation of one embodiment of traffic safety phone system provided by the utility model referring to Fig. 1.
In the present embodiment, the traffic safety phone system, mainly includes：In-vehicle multi-media system 10, sensor 20,
The call control unit being arranged on steering wheel 30, and, vehicle-speed monitoring device 40.Wherein, the call control unit is preferable
For a talk button, answering and hanging up for realization call；Further, as shown in figure 1, described set on the steering wheel
Talk button telephone receiving key 31 and hang-up key 32 can also be set respectively, be respectively used to answering and hanging up for telephone relation.
The in-vehicle multi-media system 10 includes Position Fixing Navigation System 11 and console 12；The Position Fixing Navigation System 11,
For obtaining the present position information of vehicle；The console 12 is provided with talk button 121.Preferably, vehicle-mounted more matchmakers
System system 10 also includes bluetooth conversation equipment 13 and/or mobile communication call equipment 14 (for example, 3G phones).
The sensor 20, for monitoring the dynamic friction coefficient in driving conditions.
The vehicle-speed monitoring device 40 is connected respectively with the Position Fixing Navigation System 11, the sensor 20, for receiving
The present position information of Position Fixing Navigation System 11 and the dynamic friction coefficient of the sensor 20 are stated, it is determined that the safety currently driven a vehicle
Vehicle velocity VMAX。
The console 12 is connected with the vehicle-speed monitoring device 40, for according to the safe speed VMAXWith it is currently practical
Road speed VtFiducial value, enable the telephone receiving key 31 being arranged on steering wheel 30 and hang-up key 32 conversed, or,
The talk button 121 enabled on the console 12 is conversed.
In the present embodiment, the Position Fixing Navigation System 11 is preferably but not limited to GPS (Global Position
System, global positioning system).
Specifically, in implementation process, traffic safety phone system provided by the utility model is according to gps signal positioning car
It is currently on which kind of road, searches the minimum safe distance S for corresponding to the road.For example, Class II highway is the same as the two of track
60 meters of minimum safe distance S is at least kept between adjacent car1；Highway is adjacent with track two in the case of visibility height
100 meters of minimum safe distance S is at least kept between car2.If vehicle is in the null zones such as underground parking or tunnel,
The positioning signal of Position Fixing Navigation System is labeled as invalid signals.
In the present embodiment, further, the console 12 is additionally provided with display screen 122 and voice broadcast equipment 123.
The console 12, it is additionally operable to receiving call request and currently practical road speed is in (V in the safe speedt<
VMAX) when, enable the display screen 122 and carry out real-time incoming call prompting；Otherwise, disable the display screen 122 and carry out incoming call prompting；
The voice broadcast equipment 123, for sending voice reminder in real time when receiving call request.
In a kind of achievable mode, the sensor 20 includes wheel steering angle sensor 21；The wheel steering angle passes
Sensor 21 is used to monitor drift angle θ caused by vehicle wheel rotation when driving.Further, the sensor 20 includes windscreen wiper
Sensor 22；The windscreen wiper sensor 22 is used for the windscreen wiper gear n for monitoring current setting.
In specific implementation process, the coefficient of friction on tire and ground is provided by depot and tire supplier during brake.
The change of coefficient of friction, the utility model are further passed by rainfall caused by steering wheel rotates generation drift angle in driving conditions
Sensor obtains current weather, information of road surface, and a dynamic friction coefficient μ can be obtained with COMPREHENSIVE CALCULATING, as pavement conditions compared with
Dynamic friction coefficient μ can reach 0.8 in the case of good, and less than 0.2 can be reduced in the rainy day.
Specifically, when automobile lubrication groove hard-over is about 40 °, the weight for turning to the factor is set to A, and A=(40- | turn to
Angle |)/40, A scope is：0<A<1；The current gear of windscreen wiper sensor 22 is assumed to be n, weather element weight is B, B=
(n- current gears)/n, B scope is：0<B<1；Further, according to different vehicles, car weight and tire are different, can refer to
It is C to determine the vehicle factor, and C scope is：0.8<C<1.It can then integrate and obtain dynamic friction coefficient μ：
μ=A*B*C (1)
According to positioning obtain vehicle location where road minimum safe distance S be used as braking distance, according to brake away from
From formula：
S=V2/(2gμ) (2)
The maximal rate V allowed under state at that time can be calculatedMAXValue, by speed VMAXIt is considered safe speed,
Wherein, g=9.8m/s2.If gps signal is invalid signals or μ<When 0.1, then using a relatively low default speed (it is assumed that
20km/h) it is used as safe speed VMAX。
Under different road conditions, braking distance S and friction coefficient μ can change at any time, once monitor current vehicle speed VtExceed
Corresponding safe speed VMAX, then the incoming call prompting of the display screen 122 of console 12 is disabled, and disable connecing in console 12
Listen and hang-up button, the sound prompting only sent by voice broadcast equipment 123 are sent a telegram here.Preferably, the console 12 is also set
There is timer 124；The console 12, it is additionally operable to receiving call request and currently practical road speed exceeds the peace
Full speed (Vt>VMAX) when, enable the timer 124 and carry out timing, and enable the talk button automatically after timing terminates
121 are answered.Current vehicle speed VtMore than corresponding safe speed VMAXWhen, can the default time (several seconds) afterwards from
It is dynamic to answer or uniquely allow to answer from the Answer Key 31 of steering wheel 30.Further, described traffic safety phone system is also wrapped
Include the volume adjuster 33 being arranged on steering wheel 30.Current vehicle speed VtMore than corresponding safe speed VMAXWhen, phone volume
Regulation can only be also adjusted from the button of the volume adjuster 33 of steering wheel 30.
The traffic safety phone system that the utility model embodiment provides, in vehicle travel process, if receiving phone
During call request, the present position information of dynamic friction coefficient and Position Fixing Navigation System in driving conditions reflects jointly
Driving conditions (safe speed), perform different talking modes.When ensuring that current vehicle speed is in safe speed, user can be with
Enable the telephone receiving key and hang-up key progress receiving/hang-up of talk button set on console or setting on the steering wheel
Call；And when current vehicle speed is more than and safe speed is calculated in real time, user only and can be arranged on steering wheel by enabling
On telephone receiving key and hang-up key carry out receiving/hang-up call.In addition, influenceed or speed by environment, weather conditions
When too fast, the display screen that the utility model also further disables console makes incoming call prompting, only passes through voice reminder, driver
It can allow at self-defined setting delay certain time (after such as several seconds) auto-pickup or uniquely to answer electricity from steering wheel Answer Key
Words so that the use of car phone is accordingly limited, and is avoided driver's distraction and is caused the accident.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
