Art means, and can be practiced according to the content of description, and in order to allow above and other purpose of the present utility model, feature
Can become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.
Accompanying drawing explanation
Fig. 1 show the schematic diagram of this utility model safety driving distance prior-warning device.
Detailed description of the invention
By further illustrating the technological means and effect that this utility model taked by reaching predetermined goal of the invention, below
In conjunction with accompanying drawing and preferred embodiment, this utility model is described in detail as follows.
Fig. 1 show the schematic diagram of this utility model safety driving distance prior-warning device.As it is shown in figure 1, this utility model
Safety driving distance prior-warning device includes trailer-mounted radar, vehicle speed sensor, engine speed sensor, rotary angle transmitter, vehicle
Supervisory control device and alarm device.Trailer-mounted radar, vehicle speed sensor, engine speed sensor, rotary angle transmitter and warning
Device is all connected with vehicle monitoring controller by automobile bus.In the present embodiment, automobile bus can include CAN and
LIN bus.
Introduce the effect of each element in safety driving distance prior-warning device in detail below.
Wherein, trailer-mounted radar is for measuring the speed of the distance between this car and target vehicle and target vehicle.Speed
Sensor is used for gathering this car speed.Information and vehicle speed sensor that vehicle monitoring controller can record according to trailer-mounted radar are adopted
The information of collection calculates this car and target vehicle it may happen that the time of collision.
Specifically, trailer-mounted radar constantly launches electromagnetism to target vehicle by a transmitter module with a specific frequency
Ripple, and receive, by a receiver module, the electromagnetic wave that target vehicle reflects, and send corresponding information to vehicle monitoring
Controller.Vehicle monitoring controller calculates the car of the distance between two cars and target vehicle according to the information that trailer-mounted radar transmits
Speed, and the information combining vehicle speed sensor collection judges this car and target vehicle it may happen that the time of collision, specifically calculates public affairs
Formula is:
S=1/2*C*t, V1=△ s/ △ t, T=△ s/ △ V,
Wherein, S is the relative distance between two cars, and C is the light velocity, and t is the time difference launched and receive between electromagnetic wave, V1
For the speed of target vehicle, △ s is the distance variable quantity between certain time period △ t Nei Benche and target vehicle, according to △ s and product
The ratio of the time △ t of this segment distance raw can simulate the vehicle velocity V 1 calculating target vehicle, and thus combining this car speed can obtain
Go out the speed difference △ V of Ben Che and target vehicle, can extrapolate with the difference △ V of speed according to the difference △ s of now distance
It may happen that the time T of collision.
Engine speed sensor is for a specific frequency collection engine speed.Rotary angle transmitter is for special with one
Fixed frequency collection steering wheel angle.Vehicle monitoring controller at this car calculated and target vehicle it may happen that collision time
Between judge driver less than the information gathered according to engine speed sensor and rotary angle transmitter during a setting value (such as 30s)
Within the scheduled time (such as 8～10s), whether take the corresponding workaround such as acceleration, deceleration, lane change, if driver does not has
Having and take workaround in the given time, this car will be collided with target vehicle, then by vehicle monitoring controller to dress of reporting to the police
Put and send early warning signal, alarm device send alarm, remind driver to take workaround at once.
It should be noted that in this utility model, trailer-mounted radar includes front guarantor's radar and rear guarantor's radar, front guarantor's radar and
Rear guarantor's radar is respectively arranged on front bumper and the rear bumper of automobile.Front guarantor's radar be used for measuring this car and front vehicles it
Between distance and the speed of front vehicles.Rear guarantor's radar is for measuring the distance between this car and front vehicle and front vehicle
Speed.Information and Ben Che speed that vehicle monitoring controller can record according to front guarantor's radar calculate this car with front truck it may happen that touch
The time hit, it is also possible to the information recorded according to rear guarantor's radar and Ben Che speed calculate this car and rear car it may happen that collision time
Between.If it may happen that the time of collision is less than described setting value, then according to engine speed sensor and rotary angle transmitter collection
Information judge that driver takes corresponding workaround the most in the given time, if driver is the most not in the given time
Take workaround, then automatic controlling alarming device sends alarm.
If driver does not take workaround to cause this car will collide with front truck in the given time, then send police
The alarm device of report is brake lamp, steering indicating light, steering wheel vibration motor and phonetic alarm, reminds rear car by lighting brake lamp
Slow down and walk or drive slowly, remind this car driver at once simultaneously by the way of lighting steering indicating light, making steering wheel vibration and voice message
Take workaround.If driver does not take workaround to cause this car will collide with rear car, then in the given time
The alarm device sending alarm is brake lamp, steering wheel vibration motor and phonetic alarm, reminds rear car by lighting brake lamp
Slow down and walk or drive slowly, remind this car driver to take workaround simultaneously by the way of making steering wheel vibration and voice message at once.
In sum, this utility model measures the distance between this car and target vehicle and target carriage by trailer-mounted radar
Speed, and the information combining vehicle speed sensor collection judges this car and target vehicle it may happen that the time of collision, and
During it may happen that the time of collision is less than setting value, the information gathered in conjunction with engine speed sensor and rotary angle transmitter judges
Driver takes corresponding workaround the most in the given time, and does not use corresponding workaround driver,
It is likely to cause in the case of two cars are collided by alarm device automatic alarm, it is simple to driver reacts quickly, and, nothing
Need driver frequently come back viewing scialyscope in image, be conducive to concentrate driver attention.
The above, be only preferred embodiment of the present utility model, not this utility model is made any in form
Restriction, although this utility model is disclosed above with preferred embodiment, but is not limited to this utility model, any ripe
Know professional and technical personnel, in the range of without departing from technical solutions of the utility model, when in the technology of available the disclosure above
Hold and make a little change or be modified to the Equivalent embodiments of equivalent variations, as long as being without departing from technical solutions of the utility model
Hold, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, the most still
