Abstract:
An automatic travel controlling device comprising:first detecting means for detecting a vehicle position by detecting a lane line;second detecting means for detecting the vehicle position by detecting the distance to a side wall of a road;evaluating means for evaluating a detection accuracy of said first detecting means; andcontrolling means for executing, based on the detection accuracy of said first detecting means, steering control based on the vehicle position that was detected by one of said first detecting means and second detecting means, wherein said evaluating means estimates a future detection accuracy based on a future travel path of the vehicle, said future travel path is a travel path accompanying a lane change by the vehicle, said evaluating means estimates said future detection accuracy lower than a predetermined value, and said controlling means executes, when said future detection accuracy is lower than the predetermined value, steering control based on the vehicle position that was detected by said second detecting means.
