Method for driving in a group and system thereof

A system for driving in a group, the system comprising:

• one or more processors;
• and
• a memory for storing one or more instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including:
• determining a plurality of mobility devices included in a first group for group driving,
• identifying a leading device among the plurality of mobility devices included in the first group,
• transmitting first route information set in a navigation system of the leading device to a trailing device included in the first group together with the leading device,
• setting a first route based on the first route information in a navigation system of the trailing device,
• transmitting second route information set in the navigation system of the leading device to the trailing device in response to the leading device deviating from the first route, and
• calculating a difference between i) a branch point of the first route set in the navigation system of the trailing device and a second route set in the navigation system of the leading device and ii) a current location of the trailing device,
• comparing the calculated difference with a reference value, and
• controlling the navigation system of the trailing device based on a result of the comparison of the calculated difference with the reference value, including
• controlling the navigation system of the trailing device such that, based on the calculated difference being less than or equal to the reference value, information regarding the first route and the second route is simultaneously displayed in the navigation system of the trailing device, and
• controlling the navigation system of the trailing device such that, in accordance with a selection input by a user of the trailing device to the displayed information, a selected one of the first route and the second route is set in the navigation system of the trailing device,
• wherein identifying the leading device includes:
• receiving a request to switch the leading device,
• in response to receiving the request to switch the leading device, transmitting information regarding a parking location to a navigation system of an existing leading device and a navigation system of a new leading device in the first group to guide the existing leading device and the new leading device to stop at the parking location, and
• changing the leading device from the existing leading device to the new leading device.

A non-transitory computer-readable storage medium having a group driving program stored thereon, wherein the group driving program, when executed by one or more processors, causes the one or more processors to:

• determine a plurality of mobility devices included in a first group for group driving;
• identify a leading device among the plurality of mobility devices included in the first group;
• transmit first route information set in a navigation system of the leading device to a trailing device included in the first group together with the leading device;
• set a first route based on the first route information in a navigation system of the trailing device;
• transmit second route information set in the navigation system of the leading device to the trailing device in response to the leading device deviating from the first route;
• calculate a difference between i) a branch point of the first route set in the navigation system of the trailing device and a second route set in the navigation system of the leading device and ii) a current location of the trailing device;
• compare the calculated difference with a reference value;
• and
• control the navigation system of the trailing device based on a result of the comparison of the calculated difference with the reference value, including
• controlling the navigation system of the trailing device such that, based on the calculated difference being less than or equal to the reference value, information regarding the first route and the second route is simultaneously displayed in the navigation system of the trailing device, and
• controlling the navigation system of the trailing device such that, in accordance with a selection input by a user of the trailing device to the displayed information, a selected one of the first route and the second route is set in the navigation system of the trailing device,
• wherein identifying the leading device includes:
• receiving a request to switch the leading device;
• in response to receiving the request to switch the leading device, transmitting information regarding a parking location to a navigation system of an existing leading device and a navigation system of a new leading device in the first group to guide the existing leading device and the new leading device to stop at the parking location;
• and
• changing the leading device from the existing leading device to the new leading device.
