200, establishing a matching relation between parking spaces and users, determining an idle shared time period of each parking space by processing historical use conditions of each parking space, wherein the parking spaces are shared in the idle shared parking spaces until the parking of the temporary users is used;
step 300, monitoring the use condition of the parking spaces in real time, identifying temporary vehicles, and screening the parking spaces according to the use condition of the parking spaces monitored in real time and the idle sharing time period of each parking space;
step 400, confirming the fixed users corresponding to the screened parking space list, and sending the confirmed shared parking spaces to the client by the control system;
500, the control system performs sharing on the basis of the stability probability of the parking spaces which are confirmed to be shared and the parking spaces which are screened for the first time and the parking spaces which are screened for the second time in the daily idle time period, wherein the parking spaces have low abnormal change probability and long idle time;
step 600, navigating the temporary vehicle into the specific parking space: and the control system controls the parking space navigation module to navigate the temporary vehicle to the secondarily screened parking space.
