Abstract
An other vehicle position estimation apparatus for estimating the position of another vehicle on the road using a particle filtering process includes an other vehicle map matcher and a particle number controller. The other vehicle map matcher includes an updater for updating the position of a particle distributed on a map, a likelihood calculator for calculating the likelihood of the particle position, and a position estimator configured to estimate the position of the other vehicle based on the position of the particle. The particle number controller determines a number of particles to distribute based on at least one of (i) a relative positional relationship between a subject vehicle and the other vehicle, (ii) an actual vehicle speed of the other vehicle, (iii) a distribution state of the particles, and (iv) a relationship between the position of the other vehicle and the road.
