Autonomous driving system in heterogeneous SD map and HD map environment and method for operating autonomous driving system

A method including:

• inputting, by a user, a start point and a destination by use of a first SD map provided by a service platform;
• transmitting, by the service platform, the start point and the destination to an autonomous vehicle;
• generating a global path, by the autonomous vehicle, by use of the start point, the destination, and a second SD map stored in the autonomous vehicle according to a preset program and generating a local path by use of the generated global path and a high definition (HD) map stored in the autonomous vehicle;
• operating the autonomous vehicle along the local path;
• and
• wherein:
• the global path includes a turn-by-turn (TBT) guidance between the start point and the destination,
• the first SD map has properties that do not match properties of the HD map and the second SD map, and
• the second SD map has properties matching the properties of the HD map.

A method for operating an autonomous driving system, the method including:

• inputting, by a user, a start point and a destination by use of a first SD map received by a service platform from an external navigation system and provided to the user;
• generating, by the external navigation system, a turn-by-turn (TBT) guidance by use of the start point and the destination and transmitting the start point, the destination, and the TBT guidance to the service platform;
• transmitting, by the service platform, the start point, the destination, and the TBT guidance to an autonomous vehicle;
• and
• generating, by the autonomous vehicle, a global path by use of the start point, the destination, the TBT guidance, and a second SD map stored in the autonomous vehicle according to a preset program and generating a local path by use of the global path and a HD map stored in the autonomous vehicle,
• wherein the first SD map has properties that do not match properties of the HD map and the second SD map,
• the second SD map has properties matching properties of the HD map, and
• the external navigation system is different from a navigation system built in the autonomous vehicle.

A method for operating an autonomous driving system, the method including:

• accessing, by a user, a service platform through a call software (SW);
• determining whether a navigation system is able to generate a TBT guidance using a first standard definition (SD) map;
• generating, by an autonomous vehicle, a first global path including the TBT guidance using a second SD map and a first local path matching the first global path using a high definition (HD) map upon determining that the navigation system is not able to generate the TBT guidance;
• generating, by the navigation system, the TBT guidance using the first SD map;
• generating, by the autonomous vehicle, a second global path including the TBT guidance using the second SD map and a second local path matching the second global path using the HD map upon determining that the navigation system is able to generate the TBT guidance;
• and
• operating the autonomous vehicle along the first local path or the second local path,
• wherein:
• the first SD map has properties that do not match properties of the HD map and the second SD map, and
• the second SD map has properties matching the properties of the HD map.
