Patents by Inventor Kouhei SAKURAI

Kouhei SAKURAI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10994675
    Abstract: The present invention provides technology for achieving both high responsiveness to an interrupt process and non-interference between control software. This vehicle control device comprises a storage device that stores various programs for controlling a vehicle, and a plurality of computation devices that include a first computation device and a second computation device, and that read a program from the storage device and execute the same. In addition, the storage device includes a first type of computation processing program executed not by time division and a second type of computation processing program executed by time division. The first computation device is configured to execute the first type of computation processing program, and the second computation device is configured to execute the second type of computation processing program.

  • 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.
