1. A vehicle driving assist apparatus, comprising:
- an object detection device for detecting an object existing around a vehicle and acquiring object information corresponding to information on a position and a speed of the object with respect to the vehicle;
a display device for performing an attention display operation for informing a driver of the vehicle of an existence of a target corresponding to the object to be informed to the driver of the vehicle, the attention display operation taking a predetermined display time for completing one attention display operation; and
an electric control unit for providing the display device with an attention display command for causing the display device to perform the attention display operation,wherein the electric control unit is configured;
to determine whether the target exists around the vehicle, using the object information;
to estimate a predicted reaching time necessary for the vehicle to reach the target, using the object information when the electric control unit first determines that the target exists around the vehicle;
to provide the display device with the attention display command when an attention condition that the predicted reaching time is larger than a lower limit threshold time and smaller than or equal to a display start threshold time is satisfied, the lower limit threshold time being larger than or equal to the predetermined display time and the display start threshold time being larger than the lower limit threshold time; and
not to provide the display device with the attention display command when the attention display condition is not satisfied.

Abstract
The vehicle driving assist apparatus of the invention provides a display device with an attention display command when an attention condition that a time predicted for a vehicle to reach a target is larger than a lower limit threshold time and smaller than or equal to a display start threshold time is satisfied. The lower limit threshold time is larger than or equal to a display time required for one attention display operation to be completed. The display start threshold time is larger than the lower limit threshold time. When the attention display condition is not satisfied, the apparatus does not provide the display device with the attention display command.
