DRIVE ASSIST APPARATUS

摘要

A drive assist apparatus includes an arrival window time calculation unit configured to calculate an arrival window time before the vehicle arrives at a switching completion point, a driving concentration degree estimation unit configured to estimate a driving concentration degree of a driver based on a state of the driver when the arrival window time is equal to or shorter than a predetermined time, and a stimulation providing unit configured to provide a stimulus to the driver according to the driving concentration degree. In a case where the driving concentration degree is equal to or less than a threshold value set in advance, the stimulation providing unit provides a stimulus to the driver, which is stronger than that in a case where the driving concentration degree is greater than the threshold value, or provides a stronger stimulus to the driver in accordance with reduction in the driving concentration degree.

1. A drive assist apparatus configured to execute switching of a driving mode of a vehicle from autonomous driving to manual driving at a switching completion point, the apparatus comprising:
an arrival window time calculator configured to calculate an arrival window time before the vehicle arrives at the switching completion point based on a current position and speed of the vehicle; a driving concentration degree estimator configured to estimate a driving concentration degree of a driver based on a state of the driver of the vehicle when the arrival window time is equal to or shorter than a predetermined time; and a stimulator configured to provide stimulation to the driver according to the driving concentration degree, wherein, in a case where the driving concentration degree is equal to or less than a threshold value set in advance, the stimulator is configured to provide a stimulus to the driver, wherein the stimulus has a strength stronger than another strength in a case where the driving concentration degree is greater than the threshold value, or the stimulator is configured to provide the stimulus to the driver having a strength in accordance with reduction in the driving concentration degree.
