  • Publication number: 20230419746
    Abstract: An object of the present invention is to provide a technique that enables a driver to approve transmission of vehicle data to a data center. The information system includes a first device (101-a) mounted in a vehicle, a second device (102-a) operated by a driver, and a third device (103). The first device classifies the vehicle data into the first data and the second data according to preset classification conditions. The first data is data for which an approval operation by the driver is requested. The second data is data for which the approval operation by the driver is not requested. The first device transmits the first data to the second device and transmits the second data to the third device. The second device receives the first data from the first device, and transmits the first data to the third device in response to the approval operation by the driver.

  • Patent number: 10761536
    Abstract: Vehicle systems that implement action planning for a vehicle have had difficulty in maintaining safety in the event of a failure in a recognition device since these systems generate trajectories and control the vehicle on the basis of outside-world information recognized by recognition devices. The present invention was conceived in light of the aforementioned situation and addresses the problem of maintaining safety even in the event of a failure in a recognition device of a vehicle system. This problem can be solved by an action planning device having a failure detection unit for detecting a failure in an outside-world recognition unit and a trajectory generation/determination unit for executing an action on the occurrence of a failure on the basis of outside-world information outputted by the outside-world recognition unit, wherein the trajectory generation/determination unit takes an action for coping with the failure on the basis of failure information from the failure detection unit.

  • Patent number: 10501084
    Abstract: A vehicle control system includes an external recognition means, a limit-distance calculation means, a relative-speed calculation means, and a required detection distance calculation means. When it is determined that the detectable limit distance is smaller than the required detection distance, the driver is notified that the lane change cannot be performed. When it is determined that the detectable limit distance is larger than the required detection distance, an automatic lane change of the vehicle is performed. The limit-distance calculation means detects a plurality of objects, which are sequentially detectable from the vehicle, and, based on the objects, the detectable limit distance is set in a vicinity of a farthest object.
