Autonomous driving system

An autonomous driving system mounted on a vehicle, comprising:

• an information acquisition device configured to acquire driver operation information indicating an operation by a driver of the vehicle;
• and
• an autonomous driving control device configured to perform autonomous driving control of the vehicle,
• wherein the autonomous driving control device performs:
• default lane setting processing that sets a default lane in which the vehicle travels;
• and
• vehicle travel control processing that controls the vehicle to travel in the default lane when there is no departure reason for departing from the default lane and to travel away from the default lane until there is no departure reason when there is the departure reason,
• wherein in the default lane setting processing, the autonomous driving control device refers to the driver operation information to set the default lane according to the driver's intention
• wherein the autonomous driving control device detects an autonomous driving activation instruction by the driver based on the driver operation information, and
• wherein in response to the autonomous driving activation instruction, the autonomous driving control device activates the autonomous driving control and sets a current lane at a time when the autonomous driving activation instruction is detected, as the default lane.

• wherein in the default lane setting processing, the autonomous driving control device refers to the driver operation information to set the default lane according to the driver's intention,
• wherein when there is a lane change reason, the autonomous driving control device makes a proposal of a lane change to the driver,
• wherein the autonomous driving control device determines, based on the driver operation information, whether the driver approves or rejects the proposal, and
• wherein when the driver rejects the proposal, the autonomous driving control device sets a current lane as the default lane.
