Autonomous driving assistance systems, methods, and programs obtain lane information of a road on which a vehicle is traveling, and set a planned target section for which a lane change plan of the vehicle is to be created. The systems, methods, and programs obtain, for each lane, an obstructive factor present on the road on which the vehicle is traveling and that obstructs continuation of autonomous driving assistance executed on the vehicle, and set, for each obtained obstructive factor, an avoidance route that passes through a lane avoiding the obstructive factor. The systems, methods, and programs create a lane change route that defines the lane change plan of the vehicle in the planned target section and that is set so as to preferentially pass through the avoidance route set for each obtained obstructive factor, and execute the autonomous driving assistance of the vehicle based on the lane change route.

Autonomous driving assistance system, autonomous driving assistance method, and computer program

Autonomous driving assistance systems, methods, and programs obtain road information that specifies classification of lanes located ahead in a direction in which a vehicle is traveling and road connection for each lane. The systems, methods, and programs specify, based on the road information, a planned route that is to be taken by the vehicle on a presumption that the vehicle travels without changing lanes, when the vehicle travels with autonomous driving assistance, and execute the autonomous driving assistance for the vehicle according to the specified planned route.

Autonomous driving assistance systems, methods, and programs obtain road information that specifies line types of lane markings and connection types of lanes and specify, when a vehicle travels with autonomous driving assistance, a planned route to be taken by the vehicle based on the road information. The systems, methods, and programs execute the autonomous driving assistance for the vehicle according to the specified planned route.

Drive assist systems, methods, and programs acquire a stored guide location where guidance associated with a guide event as a guide target will be provided, acquire event information indicating whether the guide event was detected from a vehicle that can selectively provide or not provide guidance associated with the guide event and which is set to provide guidance, and which detected the guide event at the guide location. The systems, methods, and programs determine whether to stop providing guidance for the guide event at the guide location based on the event information, correct stored information to stop providing guidance for the guide event at the guide location when it is determined to stop providing guidance, and acquire and transmit to the vehicle information indicating the guide location for which provision of guidance associated with the guide event has not been stopped and the guide event from the storage medium.

Drive assist system, method, and program

Warning guidance systems, methods, and programs communicate with a vehicle navigation system to provide guidance on a warning event that may occur on the vehicle. The systems, methods, and programs acquire warning event information indicating the warning event and an event vehicle on which the warning event has occurred. The systems methods and programs transmit the guidance to the vehicle traveling in a predetermined section in a case in which the warning event that has occurred a plurality of times in the predetermined section has occurred on a plurality of event vehicles, but do not transmit the guidance at another vehicle traveling in the predetermined section in a case in which the warning event that has occurred a plurality of times in the predetermined section has occurred on a single event vehicle for all of the plurality of times.

Warning guidance system, method, and program that provide information to vehicle navigation systems

Guidance devices, methods, and programs acquire a current speed of a vehicle and calculate a regeneration upper limit operation amount of the regenerative brake based on the current speed of the vehicle. The devices, methods, and programs acquire a deceleration target speed, acquire a deceleration target position, calculate a distance to the deceleration target position, and calculate a deceleration required operation amount of the brake pedal required for reducing the current speed of the vehicle to the deceleration target speed at the deceleration target position based on the acquired current speed of the vehicle, the acquired deceleration target speed, and the calculated distance to the deceleration target position. The devices, methods, and programs communicate guidance regarding the operation amount of the brake pedal based on the calculated regeneration upper limit operation amount and the calculated deceleration required operation amount.

Guidance device, guidance method, and guidance program

Systems, methods and programs are provided for a vehicle that performs braking by a regeneration brake and a friction brake. The systems, methods, and programs determine that braking by the friction brake has been performed, acquire information indicating a situation in the vicinity of the vehicle, and determine a necessary braking force required for responding to the situation in the vicinity of the vehicle. When it is determined that the braking by the friction brake has been performed in a condition where the necessary braking force is less than or equal to a maximum braking force of the regeneration brake, the systems, methods, and programs, determine energy consumed by the friction brake and communicate notification information indicating the consumed energy to a driver.
