Vehicle control system
The vehicle control system generates a target trajectory based on the driving environment of the vehicle, and performs vehicle travel control for controlling the vehicle to follow the target trajectory. The vehicle control system calculates a predicted trajectory or a degree of deviation between the predicted vehicle state and the target trajectory predicted from the current vehicle state of the vehicle. When the degree of deviation satisfies the notification providing condition, the vehicle control system provides a notification indicating a target behavior of the vehicle caused by the vehicle travel control to the occupant of the vehicle.
1 . A vehicle control system that controls a vehicle, the vehicle control system comprising
a control device, wherein
the control device is configured to
perform vehicle travel control for generating a target trajectory based on a driving environment of the vehicle and controlling the vehicle in such a manner that the vehicle follows the target trajectory,
calculate a degree of deviation between a predicted trajectory or a predicted vehicle state and the target trajectory, the predicted trajectory or the predicted vehicle state being predicted from a current vehicle state of the vehicle, and
when the degree of deviation satisfies a notification providing condition, provide a notification indicating a target behavior of the vehicle due to the vehicle travel control to an occupant of the vehicle, and
the control device is further configured to
acquire a target vehicle parameter that is necessary for the vehicle to follow the target trajectory,
acquire a predicted vehicle parameter predicted when the vehicle is assumed to travel along the predicted trajectory, and
calculate the degree of deviation based on a difference between the target vehicle parameter and the predicted vehicle parameter at a future first timing.
2 . The vehicle control system according to claim 1 , wherein the notification providing condition includes a case where the degree of deviation is equal to or larger than a predetermined threshold.
3 . The vehicle control system according to claim 1 , wherein the control device is configured to determine the notification providing condition and a content of the notification by using a machine learning model.
4 . The vehicle control system according to claim 1 , wherein the notification providing condition is allowed to be set by the occupant.
