Abstract: When a host vehicle enters a roundabout, a travel route of the host vehicle is communicated by a direction indicator to other vehicles surroundings the host vehicle. A controller computes a travel route over which a host vehicle and executes driving assist control so that the host vehicle travels along the travel route. In this driving assist method, whether or not the host vehicle has arrived at a roundabout is assessed. When the host vehicle is assessed to have arrived at a roundabout, a positional relationship between a host vehicle entrance for the host vehicle and a host vehicle exit for the host vehicle in the roundabout is assessed based on the travel route. When the host vehicle enters the roundabout, control of the direction indicator lights is performed in accordance with the positional relationship that was assessed.

Abstract: A driving control method is provided in which a processor configured to control driving of a vehicle acquires detection information around a vehicle on the basis of a detection condition that can be set for each point; extracts events which the vehicle encounters, on the basis of the detection information; creates a driving plan in which a driving action is defined for each of the events on the basis of the detection information acquired in the events; executes a driving control instruction for the vehicle in accordance with the driving plan; and determines the detection condition on the basis of the content of the driving action defined for each of the events.

Abstract: A driving assist method minimizes an incidence of lane changing within a circulatory roadway. In this driving assist method, a recognition assessment processor assesses the travel of a host vehicle, calculates a travel route over which the host vehicle is to travel, and executes a driving assist control based on the travel route. The recognition assessment processor further assesses whether the host vehicle has arrived at a roundabout having a circulatory roadway to which three or more radial roadways are connected. When an assessment has been made that the host vehicle has arrived at the roundabout, a position of a host vehicle entrance and a position of a host vehicle exit are specified. Furthermore, an entrance position is set based on a positional relationship between the host vehicle entrance and the host vehicle exit.

Abstract: A driving assist method performs a lane change control to make a lane change to an adjacent lane. The method includes: detecting whether there is a request from the host vehicle to make a lane change to the adjacent lane; detecting whether there is any intention for another vehicle traveling in the adjacent lane to make a lane change towards the host vehicle lane upon detection of a presence of the lane change; establishing a lane-change-intending other vehicle as a designated vehicle for a place-swapping lane change upon detection of a presence of the intention for another vehicle to make a lane change towards the host vehicle lane; and setting the position of the designated vehicle traveling in the adjacent lane as a target lane change to be made by the host vehicle, and performing a lane change control based on the target lane change.

Abstract: When a host vehicle enters a roundabout, a controller computes a travel route over which a host vehicle and executes driving assist control so that the host vehicle travels along the travel route. In this driving assist method, an exiting illumination area, where a direction indicator light indicating that the host vehicle is to exit a roundabout is to be illuminated based on the travel route. While the host vehicle is traveling on the roundabout, an assessment is made as to whether or not the host vehicle has arrived at the illumination area. When the host vehicle is to exit the roundabout and the host vehicle is assessed to have arrived at the illumination area, control is performed to determine to illuminate the direction indicator light that indicates the host vehicle is to exit the roundabout.

Abstract: A method of assisting a driver of a vehicle includes obtaining a feature of a road to be traveled by the vehicle with a sensor and/or a GPS system. A parameter is selected to assist a driver of the vehicle in driving a segment of the road based on the feature of the road. The parameter includes information on the location of a boundary along the road and a preferred trajectory to be driven along the road. A controller determines whether a current trajectory of the vehicle while travelling the road is deviating from the preferred trajectory of the vehicle along the road. A feedback operation is provided to assist the driver in guiding the vehicle nearer to the preferred trajectory based on the selected parameter.
