Abstract
The utility model discloses a kind of on-vehicle safety distance control system, including：Comparator, RF receiving/transmission device, ECU, OBD interface, 4G modules and mobile phone；RF receiving/transmission device is arranged on headstock and/or the tailstock；Signal input part connection RF receiving/transmission device, the signal output part connection ECU of comparator；ECU data input pin is connected with OBD interfaces and comparator respectively, data output end is connected by 4G modules with mobile communication.Advantage is, can in driving procedure the situation of change of other front/rear vehicle distances of implementing monitoring car and distance.In conjunction with the acquisition of ODB interfaces from car driving condition, relative safe space between motorcars can be drawn at once.Then by 4G or bluetooth notification mobile phone, driver is allow accurately to know current running distance.Safety coefficient in scorch is significantly improved, especially in the past ignored rear car distance can be all brought into monitoring range, rear-end collision is prevented trouble before it happens.
Description
Technical field
It the utility model is related to a kind of vehicle-mounted monitoring system, more particularly to a kind of on-vehicle safety distance control system.
Background technology
Existing vehicle-mounted monitoring system typically only considers automobile oil consumption in itself, mileage, tire pressure etc. inherent parameters, lacks
Parameter monitoring outside to car.And traffic accident is really frequently experienced in the outer situation of car, for example, in highway due to spacing farther out, two
The distance between car is not easy to judge, can not accurate judgement when spacing is less than safe distance.General driver lacks simultaneously
The weary distance trailed to rear car is observed, and is caused to be knocked into the back and is just known unexpected generation, easily causes casualties.
Utility model content
In order to solve the above-mentioned technical problem, the utility model purpose is to provide a kind of on-vehicle safety distance control system.
A kind of on-vehicle safety distance control system described in the utility model, it is characterised in that including：Comparator, radio frequency
R-T unit, ECU, OBD interface, 4G modules, tailstock warning lamp, humidity sensor and mobile phone；
Described RF receiving/transmission device is arranged on headstock and/or the tailstock, for externally sending reference RF signal and reception
Reflected radio-frequency signal；
Signal input part connection RF receiving/transmission device, the signal output part connection ECU of comparator；
Tailstock warning lamp is arranged on the tailstock, is electrically connected with ECU；
Humidity sensor is arranged on the inside of wheel close to ground, humidity sensor signal output end connection OBD interfaces；
ECU data input pin is connected with OBD interfaces and comparator respectively, data output end is led to by 4G modules and mobile phone
Letter connection.
Described system also includes bluetooth module, and the data output end of the ECU is connected by bluetooth module and mobile communication
Connect.
Described RF receiving/transmission device control signal connection ECU control output end.
A kind of on-vehicle safety distance control system described in the utility model, the advantage is that, can be in driving procedure
The situation of change of other front/rear vehicle distances of implementing monitoring car and distance.In conjunction with what ODB interfaces obtained shape is driven from car
State, relative safe space between motorcars can be drawn at once.Then by 4G or bluetooth notification mobile phone, driver is allow accurately to obtain
Know current running distance.Safety coefficient in scorch is significantly improved, especially can be by the past ignored rear car distance
All bring monitoring range into, rear-end collision is prevented trouble before it happens.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model on-vehicle safety distance control system.
Embodiment
As shown in figure 1, a kind of on-vehicle safety distance control system described in the utility model, including comparator, radio frequency are received
Transmitting apparatus, 4G modules, bluetooth module, tailstock warning lamp, humidity sensor, ECU (Electronic Control Unit, OK
Car computer), OBD (On-Board Diagnostic, onboard diagnostic system) interfaces and mobile phone.Described RF receiving/transmission device can
To be arranged in the middle part of headstock and/or the tailstock, external transmitted reference radiofrequency signal, and will reflect back into the reflected radio-frequency signal come and connect
Comparator is sent to after receipts.Comparator makes comparisons the frequency of reference RF signal with the frequency of reflected radio-frequency signal, draws frequency
The changing value and rate of change of rate are simultaneously input to ECU.ECU can draw Ben Che and front and rear car according to basic physics conversion
Respective spacing change, while the running status of this current car can be gathered by OBD interfaces, such as current road speed, from
And learn the comparatively safe distance of current vehicle speed.Spacing information is sent to mobile phone by ECU by 4G modules or bluetooth module.When driving
When the person of sailing is in driver's cabin, it can use bluetooth module transmission can be quicker.Can also utilize 4G modules by current vehicle away from
Situation is sent to the mobile phone of distal end, facilitates remote monitoring driving process.Tailstock warning lamp is arranged in the middle part of the tailstock, tailstock warning lamp
Switch controlled by ECU, ECU starts the tailstock warning lamp while alarm is sent to mobile phone, for increasing rear car to this car
Notice.Humidity sensor is arranged on the inside of wheel, and close to the position on ground, for detecting the drying journey of current road
Degree.Corresponding electric signal is fed back through into OBD interfaces and feeds back to ECU.ECU is adjusted to safe distance between vehicles according to the electric signal of feedback
Amendment, applicability is improved to polygon road conditions.
ECU can be sent warning signal in discovery spacing less than safe distance with active adversary machine, or directly control OBD connects
Mouth adjustment oil mass output.So as to change relative distance in time in extreme circumstances, unexpected injury is reduced.ECU also passes through control simultaneously
End processed connects RF receiving/transmission device, thus it is possible to vary the frequency and power of reference radio-frequency, is made more preferably for different weather and road conditions
Radiofrequency signal selection.
, can be by passing ignored vehicle parameter master by on-vehicle safety distance control system described in the utility model
Trend driver provides.Relatively conventional distance monitoring may be only available for the reversing or slow difference within ten meters, using radio frequency
Transmitting-receiving goes for more than ten meters to hundreds of meters of distance monitoring, the situation for the high speed traveling that is particularly suitable for use in.Many traffic things
Former capital is to occur to cause injures and deaths by rear car high velocity impact in the case where this car is motionless, and after driver be able to be unwilling to also keep a close watch on always
Visor is waited.The monitoring difficulty of driver can be reduced using system described in the utility model, in rear car at a high speed close to ECU can be made
Send alarm.
For those skilled in the art, technical scheme that can be as described above and design, make other each
The corresponding change of kind and deformation, and all these changes and deformation should all belong to the guarantor of the utility model claims
Within the scope of shield.
