Abstract:
Provided is an estimation device capable of estimating a current position with a high degree of accuracy. A driving support system includes: a vehicle mounted device  1  that is mounted on a vehicle and performs a control concerning vehicle driving support; a LIDAR  2 ; a gyroscope sensor  3 ; and a vehicle speed sensor  4 . The vehicle mounted device  1  acquires, from the LIDAR  2 , a measurement value z t k  indicating a positional relationship between a reference landmark Lk of an index k and the own vehicle. The vehicle mounted device  1  calculates a post estimated value x̂ t  by correcting a prior estimated value x   t  estimated, on the basis of the measurement value z t k  and a position vector m k  of the reference landmark Lk included in a map DB  10 , from a moving speed measured by the vehicle speed sensor  4  and an angular rate measured by the gyroscope sensor  3.

Claim (Index 5):
The estimation device according to  claim 3 ,\n wherein a predicting step, in which the second estimation unit calculates the first estimated position, and an updating step, in which the first estimation unit corrects the first estimated position calculated at the last predicting step based on the difference between the first information and the second information, are alternately executed, and wherein at the predicting step, the second estimation unit calculates the first estimated position at a current time based on the first estimated position corrected at the last updating step prior to the predicting step.
