Abstract: A wearable electronic device includes, a light emitter that emits light with a certain wavelength toward a body while the device is worn on the body; a light receiver that measures an incident light amount of the light with the certain wavelength; a posture measurer that measures a posture of a part of the body where the device is worn; and one or more processors. The processor is configured to, determine a posture of the part of the body where the device is worn based on a measured result measured by the posture measurer, and set a first standard value for determining whether the device is worn on the body or not based on the incident light amount in a case that the part of the body where the device is worn is in a standard posture.

Abstract: In response to confirmation request from an onboard terminal in a state where updated data after start of a temporary road change is available, a map update server distributes the updated data and instructs the onboard terminal to temporarily use the updated data. In response to the confirmation request in a state where the updated data after end of a temporary road change is available, the server instructs the onboard terminal to use the updated data from before the start of the temporary road change. In response to being instructed to temporarily use the updated data, the terminal uses the updated data that has been distributed. In response to being instructed to use the updated data from before the start of a temporary road change, the terminal temporarily uses the updated data by using map data from before the start of the temporary road change instead of the updated data.

Abstract: In a lane keeping apparatus, a first retrieving unit retrieves, for each lane, a continuously travelable distance. The continuously travelable distance for each lane represents a distance for which an own vehicle is able to travel while keeping the corresponding lane. A first identifying unit identifies a road, as a traveling road, on which the own vehicle is traveling, and one of the lanes, as a traveling lane, in which the own vehicle is traveling. A first determiner compares a continuously travelable own-lane distance with at least one continuously travelable other-lane distance to accordingly determine whether lane change from the traveling lane to at least one other lane included in the lanes is suitable.

Abstract: A vehicle unit in a vehicle determines whether the driver has encountered a difficult spot, which is difficult to understand, based on the deviation from a route, the behavior of the vehicle, and the behavior of the driver. A standard for determining the difficult spot can be corrected by learning. The vehicle unit acquires a raw image picked up at the difficult spot. The raw image is used to verify the determination of the difficult spot. The vehicle unit transmits the raw image to a center unit in a distribution center. The center unit creates a clean image based on a plurality of raw images transmitted from a plurality of vehicles. The clean image that does not show moving objects such as pedestrians and other vehicles is distributed to a succeeding vehicle arriving at the difficult spot. The vehicle unit displays the distributed clean image as a guidance image.

Abstract: A communication control system includes: a communication device that receives real-time information necessary for a vehicle control from an information delivery device via one of base stations; and a control device that controls the vehicle based on the real-time information.

The control device reduces a service level of the vehicle control for supporting at least one of a driving determination and a driving operation performed by a driver of the vehicle within the remaining time, which is shown in the prediction information.

Abstract: A vehicle navigation system disposed in a vehicle executes a route guidance function that calculates a first route by prioritizing a special lane over a normal lane as a route calculation condition and performs route guidance when a special lane use option is turned on. A determination unit determines whether the vehicle is traveling in a parallel route section in which the special lane and normal lane are in parallel. If the vehicle is traveling in the parallel route section, a second route calculation unit calculates a second route towards the destination based on an assumption that the vehicle is traveling in the normal lane. In addition, a second route guidance unit outputs a second guidance phrase at a second guidance point, such that the second guidance phrase includes a conditional phrase that conveys that the vehicle is not in the special lane.
