, can be by being sent to vehicle the embodiment of the invention discloses a kind of message prompt method, detection device and system
Whether the prompting message of lane change is needed, to reduce the hair for the situation that the track caused by vehicle is not supported by track is blocked
It is raw.Describe in detail individually below.
Fig. 1 is referred to, is that the embodiment of the present invention provides a kind of schematic flow sheet of message prompt method.Specifically, such as Fig. 1
Shown, the message prompt method of the embodiment of the present invention may include following steps：
101st, the distance between target vehicle and detection device are obtained.
Optionally, the methods described of the embodiment of the present invention can be applied particularly in detection device, and the detection device can be with
The toll collection system on highway (on the portal frame of such as charge station) is deployed in, for example it can be roadside unit RSU, or can be with
For other detection devices for being independently arranged etc., the embodiment of the present invention is not limited.
102nd, when the distance is less than default first distance threshold, support energy of the target vehicle to current lane is obtained
Force information.
Wherein, the tenability information may be used to indicate the target vehicle and support by current lane or not support by working as
Preceding track.
Optionally, the acquisition target vehicle can be specially to the tenability information of current lane：To the target carriage
The request of transmitting capacity；Receive the tenability information that the target vehicle responds capability requests return.So as to which detection device can
To the request of target vehicle transmitting capacity to ask its tenability information to current lane, target vehicle is receiving the ability
During request, you can obtain itself the tenability information to current lane, and be sent to the detection device.Wherein, the target carriage
Can be any vehicle (vehicle arrangement) in detection device such as detection device detection range, the current lane can be
Track where the target vehicle.
Optionally, the current lane can be ETC tracks；The acquisition target vehicle is believed the tenability of current lane
Breath, can be specially：Detect whether the target vehicle is configured with board units；Vehicle-mounted list is configured with when detecting the target vehicle
When first, determine that the target vehicle is supported to pass through current lane.It is further alternative, detect whether the target vehicle is configured with vehicle-mounted
Unit such as OBU can also lead to target vehicle to send OBU identification requests, and then whether identify its own by target vehicle
It is configured with OBU and feeds back to detection device, the embodiment of the present invention is not limited.
103rd, when the tenability information indicates that the target vehicle is not supported by current lane, sent out to the target vehicle
Send the prompting message for pointing out the target vehicle lane change.
Optionally, before tenability information of the target vehicle to current lane is obtained, detection device can also be sentenced
Whether the distance of breaking is more than default second distance threshold value, and the second distance threshold value is less than first distance threshold；When the distance

Wherein, the second distance threshold value is less than first distance threshold.
8. detection device according to claim 6, it is characterised in that
The processor, is additionally operable to when the tenability information indicates that the target vehicle is not supported by current lane,
Lane information is sent to the target vehicle by the transceiver, the lane information is used to indicate that the target vehicle is supported
Track information.
9. the detection device according to claim any one of 6-8, it is characterised in that
The processor, specifically for being asked by the transceiver to the target vehicle transmitting capacity, receives the target
Vehicle responds the tenability information that the capability requests are returned.
10. the detection device according to claim any one of 6-8, it is characterised in that the current lane is not parking electricity
Sub- toll collection system ETC tracks；
The processor, specifically for detecting whether the target vehicle is configured with board units, when detecting the target carriage
When being configured with board units, determine that the target vehicle is supported to pass through current lane.
