Patent ID: 7634346

Claim:
A vehicle cruise control apparatus, comprising: relative relation calculating means for calculating a relative relation between a target object detected by object detecting means, and a host vehicle; specification setting means for: setting a target relative relation, setting a first curve tolerance defining an allowable curve state, and setting a second curve tolerance defining a gentler allowable curve state than the first curve tolerance; first calculating means for calculating a first speed control amount on the basis of the relative relation and the target relative relation; second calculating means for calculating a second speed control amount on the basis of the first curve tolerance; third speed calculating means for: calculating a speed control value on the basis of the second curve tolerance, comparing the calculated speed control value to a predetermined minimum speed control value, and adopting the greater of the calculated speed control value and the predetermined minimum speed control value as a third speed control amount; and controlling means for controlling a braking/driving force of the vehicle on the basis of the least of the first speed control amount, the second speed control amount, and the third speed control amount.
