The present invention provides a sensing apparatus for a vehicle, the apparatus including: a sensing unit that is configured to sense at least one of vehicle speed information, yaw rate information, and steering angle information, and to sense a forward object existing within a sensing distance set in advance; a calculator that is configured to calculate at least one of a driving curvature radius, which is calculated based on the vehicle speed information and the yaw rate information, and a steering angular speed, which is calculated based on the steering angle information; and an adjusting unit that is configured to adjust the sensing distance to be decreased when the driving curvature radius is less than, or equal to, a predetermined curvature radius or when the steering angular speed is less than, or equal to, a predetermined angular speed.
