Abstract: Conventionally, a method in which pieces of point group information for use in position matching between a white line position detected by an object detection sensor and a white line position on a map are extracted from the white line positions according to a travel environment, has not been taken into account. In the present disclosure, a point group extraction condition is changed according to change in the travel environment so that: a process of position matching that exhibits robustness with respect to change in the travel environment can be realized; and an own position and a white line position existing at a long distance from an own vehicle can be detected with high accuracy.

Abstract: There is provided a course prediction device which includes: a vehicle information detection unit for detecting positions and velocities of multiple vehicles; a road information acquisition unit for acquiring road information indicative of positions of lanes in a road on which the vehicles are traveling; a predicted course calculation unit for calculating a predicted course of each vehicle that is a future traveling course thereof; a collision-expected vehicle extraction unit for extracting the front vehicle and the rear vehicle on the same lane that may possibly collide with each other, on the basis of the road information and the predicted courses; an avoidance-action vehicle prediction unit for predicting which one of the front and rear vehicles is an avoidance action vehicle that will take a collision avoidance action; and an avoidance course calculation unit for calculating a collision avoidance course of the avoidance action vehicle.

Abstract: To provide an own position estimation apparatus and an own position estimation method which can correct the position coordinate of own vehicle, even if a periphery monitoring apparatus in which detection points detected with good accuracy at the same timing is few is used. An own position estimation apparatus detects relative positions of a road side wall based on detection information of a periphery monitoring apparatus; converts the past relative positions, into relative positions on a basis of the current position of the own vehicle, and superimposes the current relative positions and the past relative positions after conversion; searches for a relative position relation that a coincidence degree between the relative positions of the road side wall after superposition and the positions of the road side wall of the map data becomes high; and corrects the position coordinate of the own vehicle based on the relative position relation.

Abstract: A vehicle control system is such that a mobile device transmits a cipher code to an in-vehicle control device based on pre-stored data, and the in-vehicle control device decrypts the received cipher code based on pre-stored data, in order to output a necessary control signal to equipment mounted to a vehicle, the vehicle control system including: the mobile device and the in-vehicle control device each having a memory circuit for storing data for producing cipher related data including a cipher key and an ID code, which are a source of the cipher code; wherein the vehicle control system produces the cipher related data by reading out data in the memory circuits and subjecting the data to a predetermined process determined in advance, and performs production and decryption of the cipher code based on the produced cipher related data.
