  • Publication number: 20220316893
    Abstract: A monitoring device includes: an instruction unit configured to instruct a vehicle to acquire appearance data of a monitoring object designated by a user; a detection unit configured to receive the appearance data from the vehicle and to detect whether a state of the monitoring object has changed based on the appearance data; and a monitoring result notifying unit configured to notify the user of a monitoring result of the monitoring object when the detection unit detects that the state of the monitoring object has changed.

  • Publication number: 20220315061
    Abstract: A vehicle control device that is provided in a vehicle that runs autonomously includes a detection unit for detecting a rescue target person requiring rescue based on surrounding information of the vehicle acquired by the vehicle, and a vehicle control unit for controlling the vehicle. When the rescue target person is detected by the detection unit, the vehicle control unit performs evacuation control to stop the vehicle such that the rescue target person is able to evacuate from an outside of the vehicle into the vehicle.

  • Publication number: 20220316894
    Abstract: A route search device includes a memory and a processor. The processor performs search processing for a route from a current position to a destination of a ride-sharing vehicle based on data stored in the memory. A standard route with the shortest requested time from the current position to the destination is calculated in the search processing. A high-frequency route with a frequency of encountering a pedestrian between the current position and the destination that is higher than the standard route is also calculated in the search processing. A recognition level is compared with a reference level in the search processing. When the recognition level is equal to or less than the reference level, the standard route is selected as a final route. When the recognition level is higher than the reference level, the high-frequency route is selected as the final route.

  • Publication number: 20220289247
    Abstract: A processor of a vehicle determines whether remote assistance from a remote facility is necessary during autonomous driving control. When determination is made that the remote assistance is necessary, the processor generates a target trajectory of the vehicle that includes an expected waiting position. The expected waiting position is a position where the vehicle is expected to wait for reception of an assistance signal from the remote facility. The processor calculates a traveling efficiency level indicating a level of traveling efficiency required in the vehicle, and calculates, based on the traveling efficiency level, a request timing to transmit a request signal for the remote assistance to the remote facility. When the traveling efficiency level is low in calculation of the request timing, the processor outputs a late timing.

  • Publication number: 20220284796
    Abstract: A server includes: a registration unit that registers identification information for identifying a detection target in a storage unit; a detection target determination unit that determines whether the detection target is shown in an image captured on or around a road, based on the identification information; an abnormal behavior determination unit that determines whether the detection target exhibits an abnormal behavior that is different from a normal behavior of the detection target, when the detection target is shown in the image; and an alert transmission unit that transmits an alert when the detection target exhibits the abnormal behavior.

  • Publication number: 20220194397
    Abstract: An autonomous driving system configured to make an abnormality determination for an in-vehicle device at an abnormality determination point while an autonomous vehicle is driving autonomously includes: a route search unit configured to search for a travel route from a departure point to a destination point; a route determination unit configured to determine a determination route for making the abnormality determination for the in-vehicle device from the searched travel route, based on necessity of making the abnormality determination for the in-vehicle device and the number of the abnormality determination points on the travel route; and an abnormality determination unit configured to make the abnormality determination for the in-vehicle device at the abnormality determination point while the autonomous vehicle is driving along the determination route.

  • Publication number: 20220194362
    Abstract: An automated drive device that automatically stops a vehicle in a pick-up and drop-off area in which a passenger gets and off the vehicle includes at least one processor and at least one memory that stores a program and information to be read by the at least one processor. The processor is configured to acquire the type of the passenger before the vehicle reaches the pick-up and drop-off area as a first process. The processor is configured to change a behavior for stopping the vehicle in the pick-up and drop-off area in accordance with the type of the passenger as a second process.

  • Publication number: 20220172089
    Abstract: A distribution calculation process, a similarity level calculation process, a similarity level evaluation process, and a collision determination process are executed. In the distribution calculation process, a probability density distribution related to a future position of a moving object is calculated for each behavior pattern using position data and speed data of the moving object, error data thereof, and a plurality of behavior models set for each behavior pattern corresponding to a type of the moving object. In the similarity level calculation process, a similarity level between the probability density distribution and a reference probability density distribution is calculated for each behavior pattern. In the similarity level evaluation process, the similarity level is evaluated. The similarity level includes an out-of-range level falling below a similarity allowable range.

  • Publication number: 20220153263
    Abstract: An automated driving trajectory generating device is configured to: recognize a mobile object which is located near a vehicle; calculate a host vehicle path for automated driving of the vehicle and a plurality of predicted paths of the mobile object based on a position of the vehicle on a map, a position of the mobile object on the map, and map information; calculate a predicted acceleration which is generated in the mobile object moving along a predicted path for each predicted path based on the plurality of predicted paths and a vehicle speed of the mobile object; identify a target path which is a predicted path used to generate the trajectory out of the plurality of predicted paths based on a result of comparison between the predicted acceleration and an acceleration threshold value; and generate the trajectory based on the host vehicle path and the target path.
