A travel controller generates routes respectively leading from a current lane being traveled by a vehicle to lanes except the current lane. The lanes are demarcated by lane lines and located forward in a travel direction beyond a lack-of-lane zone having no lane line. The travel controller further identifies one of the routes corresponding to a path along which the vehicle is traveling the lack-of-lane zone as a route being traveled. The path is calculated with data outputted from a sensor mounted on the vehicle. Then the travel controller controls travel of the vehicle to keep one of the lanes to which the route being traveled leads.

An object assessment device determines whether or not an object is present within a predetermined range, and has a processor configured to determine whether or not first object detection information detected at a first detection time point and second object detection information detected at a second detection time point after the first detection time point, are detecting a same object, determine whether or not a predetermined region including a location of the vehicle at the second detection time point satisfies predetermined terrain condition, when it has been determined that the same object has not been detected, determine that the object is present within the predetermined range from the vehicle, when it has been determined that the same object has been detected, or when it has been determined that the predetermined region including the location of the vehicle satisfies the predetermined terrain condition, and give notification of the assessment result.

A vehicle controller includes a processor configured to: determine a driving plan when a lane change from a host vehicle lane to another lane is requested. The driving plan represents travel behavior of a vehicle until completion of the lane change and satisfies a safety condition that the vehicle will collide with none of objects around the vehicle detected from a sensor signal obtained by a sensor mounted on the vehicle. The processor is further configured to: set a completion condition indicating a position or time at which the completion of the lane change is required, determine whether the completion condition is satisfied when the vehicle is driven according to the driving plan, control the vehicle to make the lane change according to the driving plan when the completion condition is satisfied, and restrict execution of the lane change when the completion condition is not satisfied.

Controller, method, and computer program for vehicle control

A travel controller detects a vehicle traveling behind a host vehicle from situation data depending on the situation around the host vehicle; controls travel of the host vehicle to maintain a predetermined distance or more between the host vehicle and the detected vehicle behind; causes the host vehicle to perform a first action when the distance between the host vehicle and the vehicle behind is greater than a distance threshold; causes the host vehicle to perform a second action when the distance is less than the distance threshold, the second action contributing to safe travel of the host vehicle more than the first action; sets the distance threshold at a first value when a travel situation around the host vehicle does not satisfy a predetermined short-distance condition; and sets the distance threshold at a second value smaller than the first value when the travel situation satisfies the short-distance condition.

A travel controller sets a check level depending on the situation of a lane change from a travel lane of a vehicle to a different lane before the lane change. The travel controller requests a first pre-lane-change action for the check at the lane change of the driver with a notification device when the check level is higher than a level threshold, and requests a second pre-lane-change action for the check at the lane change of the driver with the notification device when the check level is lower than the level threshold. The travel controller controls travel of the vehicle to make the lane change in the case that the driver has performed the first or second pre-lane-change action having been requested and that the situation around the vehicle satisfies a surrounding condition to be satisfied at the lane change.

A vehicle control device comprises a processor configured to determine a target merge location where the vehicle is to make a lane change from a merging lane to a main lane, in a merge zone on a scheduled route where the merging lane merges with the main lane, as a location that is before the location at the minimum distance to the end point of the merging lane allowing the driver to whom control of the vehicle has been handed over to operate the vehicle for the lane change, and when the vehicle has not completed the lane change upon reaching the target merge location, give the driver a first notification notifying that control of the vehicle will be switched from automatic control to manual control, by using a notifying unit that notifies the driver of information, or by using a vehicle controlling device that controls operation of the vehicle to perform a predetermined operation of the vehicle.

An automatic driving system includes: an information acquiring device configured to acquire driving environment information indicating a driving environment of the vehicle; a running control device configured to execute lane change control from a first lane to a second lane during automatic driving of the vehicle based on the driving environment information; and a display device configured to display an upper limit value of a running speed of the vehicle which is set by a driver of the vehicle during automatic driving. The display device is configured to display a deviation value which is calculated based on a target value of the running speed and the upper limit value along with the upper limit value during a speed-deviation running in which the running speed is higher than the upper limit value.
