Patent ID: 8150594

Claim:
A driving support device comprising: a target vehicle speed obtaining unit that obtains a target vehicle speed at a predetermined position ahead of a host vehicle; a deceleration pattern obtaining unit that obtains a plurality of deceleration patterns with different deceleration schemes for decelerating the host vehicle to the target vehicle speed; a deceleration pattern selecting unit that selects a deceleration pattern from the plurality of deceleration patterns, based on a driving operation for controlling speed of the host vehicle; and a deceleration control unit that reduces the vehicle speed of the host vehicle to the target vehicle speed before the host vehicle reaches the predetermined position, in accordance with the selected deceleration pattern; and wherein the deceleration control unit refers to reference vehicle speeds respectively set for respective, spaced reference positions up to the predetermined position in the deceleration pattern to determine whether a current vehicle speed of the host vehicle is faster than the reference vehicle speed at a reference position; and if the current vehicle speed is faster than the reference vehicle speed at the reference position, then an automatic speed reduction control is executed.
