In an embodiment of the method according to the invention, the duration T ≧ 3 seconds in step S100. Too short a duration cannot confirm whether the vehicle is about to perform the parking action. The duration is determined by considering the duration of the temporary stop in many cases such as waiting at a red light, receiving a call, etc., and is preferably determined by the duration of the red light, such as 20 seconds, so as to filter out most of the temporary stops.
For example, a method for warning a no-parking area of a vehicle specifically includes, when it is detected that a vehicle is in a stationary state (which may be obtained by a position sensor or a tire detection device inside the vehicle) or in a flameout state (which may be obtained by a detection or control device inside the vehicle), determining whether a pre-signal is stored in an environment where the vehicle is currently located, where the pre-signal may be output by a no-parking device or other devices, and if it is detected that a no-parking signal is currently located in the environment, determining that the area is in the no-parking area and issuing an alarm.
For another example, when the vehicle is detected to be in a stationary state or in a flameout state (the current working state of the traffic work is read through the APP), the history data of the detection device a is read through bluetooth, and the history data at least includes the connection data between the detection device a and other vehicles and is fed back to the user. For example, the connection record of the point X at 1 am to 5 am, the connection record of the point Y at 3 am to 8 am, and the connection record of the point Y at 2 am to 7 am are recorded in the detection device a: and if no connection record exists between the point 50 and the automobile Z and the point 8 in the morning and the point 8 in the afternoon, judging that the area is in a no-parking area in the daytime and is in a parking-enabled area at night according to the connection record.
It should be noted that there is a certain inaccuracy in this method, and a preliminary judgment result is mainly formed by summarizing previous history records. However, the stability of the determination result is slightly poor, for example, a vehicle still stays in the stop-and-go area in the stop-and-go time zone, and the record is still recorded by the detection device a. However, the record may lead to a negative guidance for subsequent parking, and for this defect, in the feedback history record, filtering the history data, for example, there are 100 parking records in the current history sample, performing a sorting process on the time of the parking records to form a time sorting table, first deleting the first 5% of the time and the last 5% of the time periods in the time sorting table, reading the vehicle parking record in each time period (taking 60 minutes as one time period) in the new time sorting table, if the usage amount of the vehicle parking record in each time period reaches 80%, regarding the time period as a stoppable time, and the rest is a no-stop area, and feeding back the formed history record to the user (for example, displaying the APP used by the user).
In a series of embodiments of the method of the present invention, for a specific implementation form of the related execution device, reference may be made to the manner in the series of embodiments of the system of the present invention, and details are not described here.
The embodiment of the invention can well solve the problem that vehicles can not be illegally parked in the no-parking area by technical means at present, can give an early warning prompt to the vehicles entering the no-parking area in advance, guides the vehicles to the no-parking area, is favorable for orderly management of the vehicles, avoids road blockage caused by the random parking and random parking of the vehicles, and keeps a good urban environment.
