Abstract: An autonomous driving system controls autonomous driving of a vehicle and calculates an interest level of a driver of the vehicle for the autonomous driving. In a driver-oriented mode, the autonomous driving system gives priority to at least one of setting by the driver, will of the driver, and ride quality. In a performance-oriented mode, the autonomous driving system gives priority to at least one of increase in a safety margin, reduction in a time to arrive at a destination, improvement in fuel economy, improvement in motion performance, and reduction in a frequency of notification to the driver. The autonomous driving system controls the autonomous driving in the driver-oriented mode in a case of a normal state, and controls the autonomous driving in the performance-oriented mode in a case of a low interest state where the interest level is lower than the normal state.

Abstract: An autonomous driving system mounted on a vehicle determines a target path based on necessary information and performs vehicle travel control such that the vehicle follows the target path. A first coordinate system is a vehicle coordinate system at a first timing when the necessary information is acquired. A second coordinate system is a vehicle coordinate system at a second timing later than the first timing. The autonomous driving system calculates, based on the necessary information acquired at the first timing, a first target path defined in the first coordinate system. Then, the autonomous driving system corrects the first target path to a second target path defined in the second coordinate system by performing coordinate transformation from the first coordinate system to the second coordinate system. The autonomous driving system uses the second target path as the target path to perform the vehicle travel control.

Abstract: A vehicle travel control device executes vehicle travel control such that a vehicle follows a target trajectory. An automated driving control device generates a first target trajectory that is the target trajectory for automated driving of the vehicle. The vehicle travel control device further determines whether or not an activation condition of travel assist control is satisfied. When the activation condition is satisfied, the vehicle travel control device generates a second target trajectory that is the target trajectory for the travel assist control. Even when the second target trajectory is generated during the automated driving, or when the second target trajectory is generated during the automated driving and a priority condition for giving priority to the first target trajectory is satisfied, the vehicle travel control device executes the vehicle travel control by giving more weight to the first target trajectory than to the second target trajectory.

Abstract: An autonomous driving system mounted on a vehicle includes: a vehicle behavior control device configured to perform vehicle behavior control that controls behavior of the vehicle; and an awareness level calculation device configured to calculate an awareness level of a driver of the vehicle. A low awareness state is a state where the awareness level is lower than a normal state. The vehicle behavior control device performs the vehicle behavior control such that another vehicle around the vehicle predicts or recognizes the behavior of the vehicle more easily in a case of the low awareness state than in a case of the normal state.
