A travel control apparatus for a vehicle includes a surrounding environment recognition device, a collision time calculator, a collision object estimator, an after-collision travel range estimator, a collision detector, and a travel control unit. The surrounding environment recognition device includes a recognizer, a collision object recognizer that recognizes an object that has a possibility to come into collision with the vehicle, and a safety degree region setter that sets safety degree regions. The collision object estimator estimates a travel route of the object and a collision position on the vehicle. The after-collision travel range estimator estimates a travel range of the vehicle after the collision based on the estimated collision position. When the collision between the vehicle and the object is detected, the travel control unit performs travel control depending on a safety degree in one of the safety degree regions in front of the travel range after the collision.

Travel control apparatus for vehicle

A travel control apparatus for a vehicle includes a surrounding environment recognition device, a collision time calculator, a collision object estimator, and an after-collision travel range estimator. The surrounding environment recognition device includes a recognizer configured to recognize a surrounding environment of the vehicle, and a collision object recognizer configured to recognize an object that has a possibility to come into collision with the vehicle in the recognized surrounding environment. The collision time calculator is configured to calculate a predicted time to the collision between the vehicle and the object. The collision object estimator is configured to, based on the predicted time to the collision, estimate a travel route of the object and a collision position on the vehicle where the object collides with the vehicle. The after-collision travel range estimator is configured to estimate a travel range of the vehicle after the collision based on the estimated collision position.

A vehicle driving assist device includes an oncoming moving body recognizer configured to recognize an oncoming moving body; a lateral position distribution characteristics acquisition unit configured to acquire distribution characteristics of a lateral position of the oncoming moving body; a risk determination region setting unit configured to set, based on the distribution characteristics, a risk determination region for calculating a risk degree; a risk degree calculator configured to calculate the risk degree for the oncoming moving body; and a preliminary collision avoidance controller configured to recognize the oncoming moving body as the obstacle in accordance with the risk degree, and perform preliminary collision avoidance control in response to the oncoming moving body prior to the emergency collision avoidance control. The risk determination region setting unit is further configured to variably set the risk determination region so that the risk degree relatively increases as the distribution characteristics tend to disperse.

Vehicle driving assist device

A vehicle driving assist device includes a processor that functions as a receiver, an emergency collision avoidance controller, and a preliminary collision avoidance controller. The receiver receives, in relation to an oncoming moving body moving in an oncoming lane adjacent to a traveling lane of a vehicle and having a velocity component in a direction opposite to a traveling direction of the vehicle, a risk degree calculated based on a history of a distance from a lane marker defining the oncoming lane to the oncoming moving body, by communication with a device outside the vehicle. Upon determination that the vehicle is highly likely to collide with an obstacle, the emergency collision avoidance controller performs emergency collision avoidance control. The preliminary collision avoidance controller recognizes the oncoming moving body as the obstacle in accordance with the risk degree, and performs preliminary control prior to the emergency collision avoidance control.

Vehicle driving assist device and vehicle driving assist system

A vehicle driving assist device comprises a risk determination region setting unit configured to set a risk determination region for calculating a risk degree that decreases as a distance outward from a center of the oncoming moving body in a width direction of the oncoming moving body increases. The risk determination region setting unit is further configured to set the risk determination region such that the risk degree is zero at a distance in a vehicle width direction between the vehicle and the oncoming moving body matching an average distance. The average distance is calculated based on distances in the vehicle width direction between the vehicle and oncoming moving bodies acquired every time the vehicle passes by the oncoming moving bodies.

A vehicle position information acquisition device includes: a position information detector that detects position information of a vehicle; a map data storage that stores a feature type of a feature on a map and a position data group in association with each other; an imaging unit that images a region ahead of the vehicle; a feature detector that detects a surrounding feature; a reference position data group extractor that extracts a reference position data group; a reference position data group storage; a comparative position data group extractor that extracts a comparative position data group; a comparative position data group storage; an error processor that associates reference position data with comparative position data having a shortest distance and calculates an error in a distance between the reference position data and the comparative position data that are associated with each other; and a correction unit that corrects the position information.

A vehicle driving assist device comprises: an oncoming moving body recognizer configured to recognize an oncoming moving body; a risk determination region setting unit configured to set a risk determination region for calculating a risk degree that decreases as a distance outward from a center of the oncoming moving body in a width direction of the oncoming moving body increases; a risk degree calculator configured to calculate the risk degree for the oncoming moving body in accordance with an overlap state between the target traveling path of the vehicle and the risk determination region; and a preliminary collision avoidance controller configured to recognize the oncoming moving body as the obstacle in accordance with the risk degree, and perform preliminary collision avoidance control in response to the oncoming moving body recognized as the obstacle prior to the emergency collision avoidance control.

An automatic driving system includes a vehicle control calculator, a f recognizer, a passerby recognition calculator, and a notifier. The vehicle control calculator causes an vehicle to perform automatic traveling along a traveling route. The recognizer acquires information on a traveling environment ahead of the vehicle. The passerby recognition calculator recognizes a passerby ahead of the vehicle based on the information on the traveling environment. The notifier notifies the passerby of a recognition state that the passerby is recognized, when the passerby is recognized by the passerby recognition calculator. The passerby recognition calculator examines whether the recognized passerby is facing a direction of the vehicle based on information on the passerby, acquired by the recognizer, and specifies the passerby as a notification target passerby when recognizing the passerby facing the direction of the vehicle. The notifier notifies the recognition state to the notification target passerby.
