Driving support equipment for vehicles
First Claim
1. A driving support equipment for a vehicle, comprising:
- a frontward information recognition unit for recognizing environs information at the front of said vehicle;
a preceding vehicle information detection unit for detecting preceding vehicle information from the environs information at the front of said vehicle;
an eye motion detection unit for detecting an eye motion of a driver who drives the vehicle;
a dispersion value processing unit for processing a value showing a dispersion of said eye motion regarding said preceding vehicle based on the preceding vehicle information detected by the preceding vehicle information detection unit and on the eye motion detected by the eye motion detection unit;
an attention state estimation unit for estimating an attention state of the driver regarding said preceding vehicle, using said value showing the eye motion dispersion; and
an alarm control unit for varying a vehicle alarm according to said estimated attention state of the driver.
