Vehicle travel control apparatus
First Claim
1. A vehicle travel control device comprising:
- a travel path recognizing device which recognizes the travel path of the vehicle;
a recognition condition determining device which determines whether or not the recognition condition of said travel path recognizing device is good; and
a travel control device which determines appropriateness for executing the travel control for the vehicle using the determination results of the recognition condition of said travel path recognizing device based on the results of the determination of said recognition condition determining device;
wherein, said travel control device determines the appropriateness of executing the travel control for the vehicle based on at least any one of a continuous conditions determined by said recognition condition determining device whether the recognition condition is favorable or unfavorable.

Abstract
The invention carries out appropriate travel control so that a vehicle travels along recognized lane markings, and at the same time, prevents making the driver feel discomfort during travel control. In the case that the white line recognition becomes not possible, the delay time TD is shortened depending on a previous continuous time interval of a recognition state. In the case that the white line recognition flag becomes possible, the delay time TD is extended depending on the previous continuous time interval. In the case that the count value of the ON time measuring counter TON is equal to or greater than the delay time TD and the white line recognizing is possible, the compensation control is permitted, and reversion to the ON state of the travel control based on recognized white lines is permitted.
