Abstract
A sensor detects an obstacle to a vehicle. An alert device provides alert information for inquiring a passenger to determine whether to continue automatic driving when a distance between the obstacle and an end of the lane is equal to or larger than a width necessary for travel based on a width of the vehicle. An input device receives a passenger's manipulation to continue automatic driving in response the inquiry provided from the alert device. A command output unit outputs a command to ease lane-based restriction on continuation of automatic driving to an automatic driving control device when the manipulation in response is received.
Claims19
A driving assistance system for supporting a vehicle, the vehicle including a sensor for detecting an obstacle in a first lane where the vehicle is traveling and an automatic driving controller for calculating an avoidance path for avoiding the obstacle detected by the sensor, controlling automatic driving of the vehicle by referring to the avoidance path calculated, and allowing automatic driving to continue by avoiding the obstacle, the driving assistance system comprising:
- an alert device that provides inquiry information for inquiring a passenger to determine whether to continue automatic driving beyond an edge of the first lane and without changing the vehicle to a second lane next to the first lane in order to avoid the obstacle when a distance between the obstacle and the edge of the first lane is equal to or smaller than a width for travel based on a width of the vehicle, and does not provide inquiry information when the distance between the obstacle and the edge of the first lane is larger than the width for travel based on the width of the vehicle;
- an input device that receives a passenger's first manipulation indicating to continue automatic driving beyond the edge of the first lane in response to the inquiry information provided from the alert device;
- and
- a command output that outputs a first command, to the automatic driving controller, to continue automatic driving beyond the edge of the first lane and without changing the vehicle to the second lane in response to the first manipulation being received by the input device.
A driving assistance device for supporting a vehicle, the vehicle including a sensor for detecting an obstacle in a first lane where the vehicle is traveling and an automatic driving controller for calculating an avoidance path for avoiding the obstacle detected by the sensor, controlling automatic driving of the vehicle by referring to the avoidance path calculated, and allowing automatic driving to continue by avoiding the obstacle, the driving assistance device comprising:
- a processor;
- and
- a storage coupled to the processor, wherein using the storage, the processor, in operation:
- provides, to an alert device, inquiry information for inquiring a passenger to determine whether to continue automatic driving beyond an edge of the first lane and without changing the vehicle to a second lane next to the first lane in order to avoid the obstacle when a distance between the obstacle and the edge of the first lane is equal to or smaller than a width for travel based on a width of the vehicle, and does not provide inquiry information when the distance between the obstacle and the edge of the first lane is larger than the width for travel based on the width of the vehicle;
- receives a response signal for a passenger's manipulation indicating to continue automatic driving beyond the edge of the first lane in response to the inquiry information provided by the alert device;
- and
- outputs a command, to the automatic driving controller, to continue automatic driving beyond the edge of the first lane and without changing the vehicle to the second lane in response to the response signal being received.
A driving assistance method adapted for a driving assistance device for supporting a vehicle, the vehicle including a sensor for detecting an obstacle in a first lane where the vehicle is traveling and an automatic driving controller for calculating an avoidance path for avoiding the obstacle detected by the sensor, controlling automatic driving of the vehicle by referring to the avoidance path calculated, and allowing automatic driving to continue by avoiding the obstacle, the driving assistance method comprising:
- providing, to an alert device, inquiry information for inquiring a passenger to determine whether to continue automatic driving beyond an edge of the first lane and without changing the vehicle to a second lane next to the first lane in order to avoid the obstacle when a distance between the obstacle and the edge of the first lane is equal to or smaller than a width for travel based on a width of the vehicle, and not providing inquiry information when the distance between the obstacle and the edge of the first lane is larger than the width for travel based on the width of the vehicle;
- inputting a response signal for a passenger's manipulation indicating to continue automatic driving beyond the edge of the first lane in response to the inquiry information provided by the alert device;
- and
- outputting a command, to the automatic driving controller, to continue automatic driving beyond the edge of the first lane and without changing the vehicle to the second lane in response to the response signal being input.
