Patent ID: 8862342

Claim:
A driving assistance device that assists vehicle deceleration driving, comprising: a target deceleration pattern generating unit configured to generate a target deceleration pattern for the deceleration driving; a start position determining unit configured to determine a deceleration start point where the deceleration driving starts on the basis of the target deceleration pattern; and a storage unit configured to store information about a deceleration operation of a driver, wherein the target deceleration pattern generating unit generates the target deceleration pattern including a first deceleration pattern in which deceleration in a section from a predetermined position, which is set on the basis of a time when the driver starts the deceleration operation, to a target stop position is set and a second deceleration pattern in which deceleration in a section to the predetermined position is set, and the deceleration in the first deceleration pattern is more than the deceleration in the second deceleration pattern.
