Remote support method and remote support system

1 . A method for providing a remote support for a plurality of mobile vehicles, the method comprising:

calculating a processing load of a server managing the remote support or data traffic per unit time in data sending/receiving between a target mobile vehicle of the remote support and the server;

acquiring positional information on a current location and a destination of the target mobile vehicle and map information containing the current location and the destination;

when the processing load is greater than or equal to an upper limit load or when the data traffic per unit time is greater than or equal to an upper limit amount, making a proposal to the target mobile vehicle for an avoidance route for avoiding an occurrence of the remote support based on the positional information and the map information; and

controlling the target mobile vehicle to autonomously travel in accordance with the avoidance route, wherein:

the making the proposal for the avoidance route comprises:

generating the avoidance route at the server; and

sending the avoidance route from the server to the target mobile vehicle;

the remote support includes a remote assistance and a remote driving of the target mobile vehicle, and

the avoidance route is a route for avoiding an occurrence of at least one of the remote assistance and the remote driving,

the method further comprising:

storing the map information including information on respective positions of roads, respective shapes of the roads, respective positions of intersections and constructions, information on an occurrence level of the remote support, the occurrence level corresponding to a frequency of occurrence of the remote support;

setting the occurrence level in advance by a prediction model for each zone formed by dividing the map and based on provision history of the remote support; and

storing mobile vehicle information that includes information on a free space of a memory device of the target mobile vehicle including log information, the log information includes image information around the target mobile vehicle, a speed, an acceleration, and a steering angle of the target mobile vehicle sent from the target mobile vehicle to the server in response to occurrence of an event in which the target mobile vehicle is provided with the remote support, instruction information received by the target mobile vehicle from the server during the event in which the mobile vehicle is provided with the remote support, and control amount information of driving devices of the target mobile vehicle based on the instruction information.

2 . The method according to claim 1 , the method further comprising:

in response to the processing load being less than the upper limit load and the data traffic per unit time is less than the upper limit amount and in response to the free space being equal to or less than a lower limit capacity, making the proposal to the target mobile vehicle for the avoidance route.

3 . A system for providing a remote support for a plurality of mobile vehicles, comprising:

a server for managing the remote support,

wherein the server is configured to:

calculate a processing load of the server or data traffic per unit time in data sending/receiving between a target mobile vehicle of the remote support and the server;

acquire positional information on a current location and a destination of the target mobile vehicle and map information containing the current location and the destination;

make a proposal to the target mobile vehicle for an avoidance route for avoiding an occurrence of the remote support based on the positional information and the map information when the processing load is greater than or equal to an upper limit load or when the data traffic per unit time is greater than or equal to an upper limit amount; and

controlling the target mobile vehicle to autonomously travel in accordance with the avoidance route, wherein

the making the proposal for the avoidance route comprises:

generating the avoidance route at the server; and

sending the avoidance route from the server to the target mobile vehicle;

the remote support includes a remote assistance and a remote driving of the target mobile vehicle, and

the avoidance route is a route for avoiding an occurrence of at least one of the remote assistance and the remote driving,

the server further configured to:

store the map information including information on respective positions of roads, respective shapes of the roads, respective positions of intersections and constructions, information on an occurrence level of the remote support, the occurrence level corresponding to a frequency of occurrence of the remote support;

set the occurrence level in advance by a prediction model for each zone formed by dividing the map and based on provision history of the remote support; and

store mobile vehicle information that includes information on a free space of a memory device of the target mobile vehicle including log information, the log information includes image information around the target mobile vehicle, a speed, an acceleration, and a steering angle of the target mobile vehicle sent from the target mobile vehicle to the server in response to occurrence of an event in which the target mobile vehicle is provided with the remote support, instruction information received by the target mobile vehicle from the server during the event in which the mobile vehicle is provided with the remote support, and control amount information of driving devices of the target mobile vehicle based on the instruction information.
