1. A driving assist apparatus comprising:
- a controller configured to control a decelerator included in a host vehicle to perform driving assist,wherein the controller is configured to;
acquire information on a shape of a road ahead of the host vehicle in a traveling direction;
when it is determined, based on the acquired shape of the road, that there is a curve ahead of the host vehicle in the traveling direction,measure and store a maximum value of deceleration, based on sensor signals from an acceleration sensor included in the host vehicle, the deceleration being caused in the host vehicle as a result of a driving operation performed by a driver on a straight road located before a start point of the curve;
calculate an average of the stored maximum values of deceleration as a target deceleration value being used during execution of the driving assist through control of the deceleration of the host vehicle by the decelerator; and
when it is determined, based on the acquired shape of the road, that there is the curve ahead of the host vehicle in the traveling direction, and that driving assist is executed through control of the deceleration of the host vehicle by the decelerator,execute the control of the deceleration of the host vehicle by the decelerator for the driving assist such that the maximum value of deceleration of the host vehicle during the driving assist coincides with the target deceleration value to reflect preference of the driver to the driving assist and the deceleration of the host vehicle before entering the curve.

Abstract
The driving assist apparatus includes a controller configured to control a decelerator included in a host vehicle to perform driving assist. The controller acquires information on the shape of a road ahead of the host vehicle in the traveling direction. When it is determined based on the acquired shape of the road that there is a curve ahead of the host vehicle in the traveling direction and driving assist is executed through control of the deceleration of the host vehicle by the decelerator, the controller controls the maximum value of deceleration of the host vehicle so as to coincide with the target deceleration value.

12. A driving assist method for a host vehicle comprising steps of:
-
acquiring, by a computer, information on a shape of a road ahead of the host vehicle in a traveling direction; determining, by the computer, based on the acquired shape of the road, whether there is a curve ahead of the host vehicle in the traveling direction, and if so, measuring and storing, by the computer, a maximum value of deceleration, based on sensor signals from an acceleration sensor included in the host vehicle, the deceleration being caused in the host vehicle as a result of a driving operation performed by a driver on a straight road located before a start point of the curve, and calculating, by the computer, an average of the stored maximum values of deceleration as a target deceleration value being used during execution of the driving assist through control of the deceleration of the host vehicle by the decelerator; and determining, by the computer, based on the acquired shape of the road, whether there is the curve ahead of the host vehicle in the traveling direction and driving assist is executed through control of the deceleration of the host vehicle by the decelerator, and if so, executing, by the computer, the control of the deceleration of the host vehicle by the decelerator for the driving assist such that the maximum value of deceleration of the host vehicle during the driving assist coincides with the target deceleration value to reflect preference of the driver to the driving assist and the deceleration of the host vehicle before entering the curve.
