Abstract

Disclosed is a route evaluation device that enables traveling along a route in consideration of an operation of the driver of another vehicle, and can realize a safer traffic environment. A route evaluation device includes a route candidate generation section that generates route candidates of a host-vehicle, a route prediction section that predicts routes of another vehicle, a classification section that classifies the interference states of the route candidates of the host-vehicle and the predicted routes of another vehicle into a plurality of interference forms, and a route evaluation section that evaluates the routes of the host-vehicle on the basis of the interference forms classified by the classification section.

Claims5

Dependent claims

A traveling assist device of a host vehicle, comprising;

a vehicle speed sensor that detects speed information of the host-vehicle;
a vehicle position sensor that detects position information of the host-vehicle;
and
an electronic control unit that includes a central processing unit, wherein the electronic control unit is operatively connected to the vehicle speed sensor, the vehicle position sensor, and the host-vehicle, and wherein the electronic control unit is configured to:
acquire environmental situation information regarding a vicinity of the host-vehicle, wherein the environmental situation information includes a position and a state of a mobile object in the vicinity of the host-vehicle;
predict a future state of the host-vehicle based on one or more of the speed information, the position information of the host-vehicle, and the environmental situation information including the position and the state of the mobile object in the vicinity of the host-vehicle;
generate a plurality of route candidates of the host-vehicle;
predict a future state of the mobile object in the vicinity of the host-vehicle based on the environmental situation information;
generate a plurality of route candidates of the mobile object;
classify interference states of the route candidates of the host-vehicle and the route candidates of the mobile object into a plurality of interference forms stored in advance based on whether or not the host vehicle or the mobile object is violating traffic rules;
determine a route of the host-vehicle based on the classified interference states;
and
control the traveling of the host-vehicle based on the determined route.
