Driving assistance apparatus for vehicle

Abstract

A driving assistance apparatus for a vehicle includes an environment information acquisitor, a vehicle position estimator, a target route setter, and a controller. The environment information acquisitor acquires environment information in front of the vehicle. The vehicle position estimator estimates a position of the vehicle on a road. The target route setter sets a target route of the vehicle. The controller causes the vehicle to travel along the target route. The controller includes an intersection determiner, a right-left turn determiner, a route generator, and an intervention controller. The intersection determiner determines whether an intersection is in front of the vehicle based on the environment information. The right-left turn determiner determines whether the vehicle turns right or left at the intersection. The route generator generates correct and erroneous routes. The intervention controller executes intervention control to return a traveling direction of the vehicle toward the correct route from the erroneous route.
