DRIVE ASSIST APPARATUS AND METHOD

摘要

A driving assist apparatus includes: a regenerative braking force calculation unit for calculating an index by which a vehicle can be decelerated only by a regeneration operation of the electric motor; a display unit for displaying an indication that the vehicle can be decelerated only by the regeneration operation of the electric motor in a recognizable manner to driver of the vehicle; a prediction unit for predicting a target position at which the vehicle is decelerated to a target speed; and a timing calculation unit for calculating a timing at which the display unit displays the indication that the vehicle can be decelerated only by the regeneration operation, according to a distance or time required until a speed of the vehicle becomes the target speed by a deceleration performed based on the index, a distance or time required until the driver starts a deceleration operation, and the predicted target position.
