Abstract

The position of the distance measurement point is acquired from the distance measurement sensor, the lateral position of the road boundary is estimated from the most frequent value in the frequency distribution indicating the distribution status of the distance measurement point group. When multiple peaks having a frequency in the frequency distribution equal to or higher than a predetermined value are disposed on one of the left side and the right side of the vehicle, it is determined whether the estimation of the road boundary is in an unstable state. The vehicle position on the map is specified, and the traveling lane of the vehicle is estimated based on the information about the numerical number of traffic lanes and the positional relationship of the road boundary without using the estimation result of the lateral position of the road boundary in the unstable state.
