Abstract

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.
