Embodiment provides one kind and parks cars anti-collision reminding method, for reminding driving vehicle, avoids hitting and parks cars.This method
It can be applied in car-mounted terminal, car-mounted terminal is on parking cars, to be managed to parking cars.
In practical applications, car-mounted terminal can be integrated in one with the other systems on parking cars, can also be independent
It is set on parking cars.
Fig. 1 is a kind of flow chart of anti-collision reminding method that parks cars shown according to an exemplary embodiment.The implementation
The executive agent of example is car-mounted terminal, and as shown in Fig. 1, this method includes：
Step 101, detection are equipped with the state of the target vehicle of car-mounted terminal.
Wherein, the state of target vehicle includes：Halted state and starting state.Target vehicle is detected by car-mounted terminal
State.
Step 102, after detecting that target vehicle is in halted state, obtain target vehicle with each of in predeterminable area
The distance between vehicle information.
Specifically, there are one car-mounted terminal, each car-mounted terminal, which corresponds to, obtains target vehicle for installation on each target vehicle
The distance between each vehicle in predeterminable area information.The number of vehicle can be for 0,1 or more in predeterminable area
It is a, when 1 or multiple vehicles drive into predeterminable area, car-mounted terminal can obtain each driving vehicle and target vehicle it
Between range information；When not having vehicle in predeterminable area, car-mounted terminal does not obtain range information then.
Wherein, " predeterminable area " refers to：With the circle being equipped between the target vehicle of car-mounted terminal for certain distance
In regional extent.The size of certain distance can be designed according to practical application scene, for example, certain distance can be
0.1~6m, such as it can be 0.1m, 0.3m, 2m, 3m, 4m, 5m, 6m etc..
It is understood that the vehicle in predeterminable area includes：It parks cars and driving vehicle, and the position of target vehicle
It remains unchanged, so, " range information " between vehicle and target vehicle in predeterminable area includes：Gradual increased distance,
The distance being gradually reduced, the distance remained unchanged.
Step 103 predicts whether the vehicle in predeterminable area hits target vehicle according to range information.
Wherein, " prediction, which is hit, to park cars " can be understood as：Any one driving vehicle and target carriage in predeterminable area
The distance between be gradually reduced and reach default spacing, driving vehicle will hit or close to target vehicle, but it is practical simultaneously
Do not hit target vehicle.The size of default spacing can be set according to practical application scene, and satisfaction makes driving vehicle
The action for stopping that target vehicle can be hit can be made.For example, default spacing can be 0.1~0.4m, such as can
Think 0.1m, 0.2m, 0.3m, 0.4m etc..
The action of target vehicle can be hit by, which stopping, includes：Driving vehicle stops traveling or adjustment travel direction etc..
If step 104, prediction result are that can hit target vehicle, prompting message is sent out.
Prompting message refers to：Driving vehicle prompting can be given, to prevent driving vehicle from hitting the information of target vehicle.

So far, through the above steps 101 to step 104, it can be achieved that anti-collision reminding to parking cars.
There are many ways to realizing step 102, based on premise easy to implement, accurate, efficiently obtaining range information
Under, provide following two examples：
In one possible implementation, as shown in fig. 2, target vehicle and each vehicle in predeterminable area are obtained
The distance between information, including：
Step 102a1, multigroup signal wave is sent in real time, and records the delivery time of every group of signal wave.
Signal wave sending device for sending multigroup signal wave in real time can be that the distance being set on car-mounted terminal passes
Sensor, radar etc..Signal wave can be laser, ultrasonic wave, microwave etc..
Signal wave sending device could be provided as it is multiple and circumferentially uniformly distributed on target vehicle, in order to pre-
If multigroup signal wave is uniformly sent out in region, so obtain positioned at target vehicle surrounding vehicle and its distance between information,
Prevent each position in the front, rear, left and right of target vehicle from being hit.
Record every group of signal wave delivery time can by be set on car-mounted terminal instruction, program, code set is by remembering

Number wave receiving device can be the range sensor being set on car-mounted terminal, radar etc..Signal wave receiving device and signal wave
Sending device can be the range sensor being integrated in one, radar etc., so that encountering the signal wave of vehicle can return along former road
It returns and is received.
When the signal wave of return is received, recording unit or the recording device records time of reception.In this process, it returns
Signal wave can be one group, the multigroup or signal wave that does not return.When the signal wave of return is multigroup, recording unit
The time of reception of the signal wave of every group of return is recorded respectively.When the signal wave not returned, recording unit or recording device
It does not work.
For the ease of efficiently, fully use car-mounted terminal, signal wave can be controlled and encounter barrier in predeterminable area
It returns, beyond after predeterminable area, signal wave is returned and will not be received after encountering barrier, although being received, but not note
Record the time of reception of the return signal wave.
Wherein, predeterminable area can be found in the elaboration in step 102.
Step 102a3, according to the pre-set velocity of the delivery time of the signal wave of return, the time of reception and signal wave, meter

Wherein, location information can be longitude and latitude, for example, with coordinate (x1、y1) indicate, wherein x1Represent target vehicle
The longitude coordinate of present position, y1Represent the latitude coordinate of target vehicle present position.
Step 102b2, it according to the location information of each vehicle in the location information of target vehicle, predeterminable area, calculates
Obtain the distance between each vehicle in target vehicle and predeterminable area information.
Specifically, it can be calculated between each vehicle in target vehicle and predeterminable area by following formula (2)
Range information：
Wherein, L is target vehicle and the distance between the vehicle in predeterminable area, unit m；, (x1、y1) and
(x2、y2) be respectively a vehicle in the longitude and latitude and predeterminable area of target vehicle longitude and latitude.
In one possible implementation, step 103, according to range information predict predeterminable area in vehicle whether hit
Target vehicle is hit, including：
Step 1031, according to range information, judge whether the distance between the vehicle-to-target vehicle in predeterminable area subtracts
As little as default spacing.

For a driving vehicle：Compare the distance between current time vehicle-to-target vehicle and last moment between the two at a distance from,
If reducing, illustrate vehicle close to target vehicle.
Step 1032, when the distance between the vehicle-to-target vehicle in predeterminable area is decreased to default spacing, prediction
Target vehicle can be hit.
It should be noted that when the distance between driving vehicle and target vehicle reduce and are less than default spacing, explanation
The distance between driving vehicle and target vehicle smaller, at this point, prediction driving vehicle but will hit target vehicle.
Description for presetting spacing can be found in elaboration in step 103.
In one possible implementation, stop hitting the dynamic of target vehicle in order to make driving vehicle make in time
Make, in step 103, when the distance between each vehicle-to-target vehicle in predeterminable area is decreased to default spacing, hair
Go out primary prompting message；When the distance between each vehicle-to-target vehicle in predeterminable area reduces and less than default spacing
When, send out advanced prompting message.
