A travel controller of a vehicle that can travel on a road under autonomous driving control detecting two-wheelers, including bicycles, located in surroundings of the vehicle from surrounding data representing the surroundings of the vehicle generated by a surrounding sensor mounted on the vehicle, determining whether a target road on which the vehicle was traveling when the surrounding data in which a two-wheeler was detected was generated is a shared road on which travel by bicycles is permitted, when it is determined that the target road is a shared road, notifying a driver of the vehicle of a transition demand demanding transition in control of the vehicle from autonomous driving control to manual driving control requiring driving operations by the driver of the vehicle, and when it is determined that the target road is not a shared road, not notifying the driver of the transition demand.

Travel controller and travel control method

When an object that may possibly collide with a vehicle is detected from a sensor signal of one of sensors mounted on the vehicle, a vehicle controller changes the level of autonomous driving control applied to the vehicle from a first level that does not require a driver to operate an accelerator and steering and does not require the driver to look around the vehicle to a second level that requires the driver to look around the vehicle but does not require the driver to operate an accelerator and steering. When an object that may possibly collide with the vehicle is detected from sensor signals of two or more of the sensors, the vehicle controller changes the level of autonomous driving control from the first level to a third level that requires the driver to operate at least an accelerator or steering.

Controller, method, and recording medium for reducing frequency of autonomous control level application

A vehicle controller includes a processor configured to detect a vehicle ahead of a host vehicle from time-series sensor signals obtained by a sensor provided on the host vehicle for sensing objects around the host vehicle, track the vehicle ahead detected from the time-series sensor signals, determine whether the vehicle ahead has performed an avoidance action, based on the result of tracking, detect, when the vehicle ahead has performed an avoidance action, a trajectory of an edge of the vehicle ahead opposite a direction of avoidance in the avoidance action, and control travel of the host vehicle so that an edge of the host vehicle opposite the direction of avoidance moves along the detected trajectory.

Vehicle controller, method, and computer program for vehicle control

A vehicle controller includes a processor configured to determine whether a vehicle under manual driving control is in a situation that allows for starting autonomous driving control of the vehicle, switch, when the vehicle is in a situation that allows for starting autonomous driving control, control of the vehicle from manual driving control to autonomous driving control in the case where operating mode of a device related to ensuring visibility of a driver of the vehicle is set to automatic mode to automatically control the device, and continue manual driving control in the case where the operating mode of the device related to ensuring the driver's visibility is set to manual mode to manually control the device and where the driver's visibility will not be ensured unless the device operates.

An apparatus for message notification displays a message to be known to a driver of a vehicle on a display disposed in front of a driver's seat on which the driver is sitting, when a change in environment around the vehicle causing the driver to turn his/her attention forward, an action of the vehicle that the driver can sense, or operation by the driver of a vehicle-mounted device in a front area of the vehicle is detected, in the case where travel of the vehicle is controlled in autonomous driving mode in which driving operation by the driver is unnecessary, and where a looking direction of the driver is not a direction related to the driving operation.

Apparatus and method for message notification

A vehicle control device has a processor configured to calculate an average speed of a vehicle traveling in a traffic lane and another vehicle in a predetermined range from the vehicle, for each of multiple traffic lanes of a traveling road on which the vehicle is traveling, as a traffic lane average speed, to determine whether the traffic lanes are congested based on the traffic lane average speed for each of the multiple traffic lanes of the traveling road and to estimate whether the traveling road as a whole is congested based on a proportion of traffic lanes of the traveling road that are congested, and to decide to drive the vehicle by automatic control when the traveling road as a whole is congested.

Vehicle control device, storage medium storing computer program for vehicle control, and method for controlling vehicle

A vehicle controller includes a processor configured to determine whether there is fogging on a window of a vehicle or a sign of fogging thereof, based on a fogginess sensor signal indicating a physical index related to the degree of fogging of the window of the vehicle or operation of a vehicle-mounted device of the vehicle capable of defogging operation. The fogginess sensor signal is obtained by a fogginess sensor provided on the vehicle. The processor is further configured to change a driving control level applicable to the vehicle so as to increase or prevent decreasing the degree of a driver's involvement in driving the vehicle, depending on the driving control level currently applied to the vehicle, upon determination that there is fogging on the window of the vehicle or a sign of fogging thereof.

A vehicle controller for automated driving control of a vehicle in traffic congestion includes a processor configured to sense at least one another vehicle around the vehicle, based on a sensor signal obtained by a sensor for sensing a situation around the vehicle, the sensor being mounted on the vehicle; calculate a motion value indicating motion of the sensed at least one other vehicle; determine, when the motion value satisfies a congestion relief condition, that congestion is relieved around the vehicle; and set the congestion relief condition, based on road environment information indicating environment of a road around the vehicle.
