1. A driving support apparatus for a vehicle, comprising:
- a vehicle speed setting unit for setting a set vehicle speed based on an operation state to an operation input unit by a driver;
a constant speed cruise control unit for performing constant cruise control using the set vehicle speed as a target speed;
an imaging unit for capturing an image ahead of a subject vehicle;
a speed limit recognizing unit for recognizing a speed limit displayed on a sign on a road based on the image captured by the imaging unit; and
a vehicle speed switching unit that, when a speed limit different from the set vehicle speed is recognized by the speed limit recognizing unit, temporarily performs a standby mode in which the set vehicle speed can be switched to the recognized speed limit and displays the set vehicle speed and the recognized speed limit so that the speeds can be compared with each other, whereinthe operation input unit includes an up switch for changing a current set vehicle speed to be higher and a down switch for changing a current set vehicle speed to be lower,during the standby mode entered as a result of recognizing the speed limit higher than the set vehicle speed, the vehicle speed switching unit switches the set vehicle speed to the speed limit when the up switch is operated by the driver and maintains the set vehicle speed when the down switch is operated by the driver, andduring the standby mode entered as a result of recognizing the speed limit lower than the set vehicle speed, the vehicle speed switching unit maintains the set vehicle speed when the up switch is operated by the driver, and switches the set vehicle speed to the speed limit when the down switch is operated by the driver.

Abstract
There is provided a driving support apparatus for a vehicle. When a speed limit that is not equal to a set vehicle speed is detected by a stereo image recognition device, a cruise control unit temporarily performs a standby mode in which a value of the set vehicle speed can be switched to the speed limit, and displays the set vehicle speed and the speed limit so that the speeds can be compared with each other and selectively maintains the set vehicle speed or switches the set vehicle speed to the speed limit based on an operation state by a driver during the standby mode.
