when the number of the vehicles joining the motorcade group is less than the preset number of the vehicles, the manager selects a following mode or a motorcade mode;
and when the number of the vehicles joining the motorcade group is larger than the preset number of the vehicles, the server automatically starts the motorcade mode.
When three vehicles A, B and C follow the vehicle, one vehicle A is selected as a head vehicle, B follows A, C follows B, and then the two-dimensional code is scanned by the mobile phone to join in the same group, and at the moment, the group information appears in all vehicles A, B and C. After the motorcade starts to run, the position of the vehicle A is acquired through a GPS, the turning operation of the vehicle A is acquired through a sensor arranged in the vehicle, a real-time navigation map is generated and sent to central control screens of the vehicle B and the vehicle C after being processed by a server, the vehicle B and the vehicle C can check a driving route following the vehicle A through the central control screens, and the turning operation of the vehicle A can be noticed. A car needs the plan route of traveling, when A traveles at the excessive speed, the distance between A and B is drawn greatly, and B car is difficult to follow, and the server judges that the distance is greater than the preset scope between two AB cars this moment, reminds A to slow down and waits for B car to follow this moment.
When N (N is more than 4) vehicles need to follow a vehicle team, the administrator sends the two-dimensional code to all vehicle owners in the forms of WeChat and the like, after all vehicle owners enter the group to be found out, the vehicle team starts to run, and at the moment, the vehicle team group automatically selects a vehicle team mode. In the fleet mode, each vehicle can obtain an integral real-time navigation map, and the head vehicle needs to display the navigation of the planned route while receiving the integral condition because the head vehicle needs to run the planned route, and the navigation can be simultaneously carried out through a mobile phone and can also be checked through split screen operation. The following vehicles only need to follow the front vehicle without paying attention to the operation of the head vehicle, and the self driving and turning are carried out according to the real-time position and the turning operation of each vehicle. In this case, although only the front vehicle is followed, the routes of all the vehicles can be seen in the real-time navigation map, so that the monitoring of other vehicles on the whole vehicle fleet is facilitated, and the error that some vehicles do not follow the vehicle fleet is avoided. The vehicle following can be accurately carried out no matter the motorcade is in the mode.
Besides, the group administrator can also subscribe other services, such as controlling the turning on of vehicle atmosphere lamps, or controlling the lamps of all vehicles to start simultaneously, and the like, so that the overall driving atmosphere is improved and better driving experience is added to the group administrator under the condition that safe driving is not influenced.
