Abstract: It is possible to reduce inadvertent vehicle behavior during autonomous driving. A vehicle position detection device includes: a satellite positioning position calculation unit 15 that receives a satellite positioning position signal of a vehicle and calculates a satellite positioning position of the vehicle; an autonomous navigation position calculation unit 16 that receives an autonomous navigation position signal of the vehicle and calculates an autonomous navigation position of the vehicle; a distance calculation unit 17 that calculates a positional difference between the satellite positioning position and the autonomous navigation position; a recording unit that stores a plurality of parameter sets in which a plurality of thresholds for allowing a positional difference for each speed of the vehicle are set per vehicle characteristic; a selection unit 14 that selects a parameter set according to the vehicle characteristic from a plurality of parameter sets 11 to 13 stored in the recording unit; and a determination unit 18 that outputs the satellite positioning position when the positional difference is within the threshold, and outputs the autonomous navigation position when the positional difference is out of the threshold.

Abstract: Provided is a vehicle control device capable of more reliably avoiding a collision between an obstacle and a vehicle or reducing a collision damage by more accurately estimating a type and a risk of the obstacle than a conventional vehicle control device. A vehicle control device 100 is a control device mounted on a vehicle V, and includes a three-dimensional object information generation unit 121, a damage degree map generation unit 122, and a travel control unit 123. The three-dimensional object information generation unit 121 detects an object around the vehicle V and generates three-dimensional object information based on external environment information output from the external sensor V1 mounted on the vehicle V. The damage degree map generation unit 122 generates information on a plurality of split regions obtained by splitting a target region including the object in each of a longitudinal direction and a height direction based on the generated external environment information, and sets damage degrees respectively to the plurality of split regions depending on magnitudes of damage at a time of collision of the vehicle V. The travel control unit 123 controls travel of the vehicle V to minimize a collision damage degree corresponding to the damage degree set in the split region.
