  • Patent number: 11367291
    Abstract: A traffic signal display estimation system recognizes, based on the position information of a vehicle and a traffic signal information, a traffic signal included in a camera image, identifies a traffic signal display for each recognized traffic signal, and calculates, for each traffic signal, a first evaluation value indicating the certainty of the identified traffic signal display. The system integrates, based on a traffic-signal-to-traffic-signal relational information, a forward traffic signal that is ahead of the travelling direction and that the vehicle should follow and a traffic signal correlated with the forward traffic signal in terms of the traffic signal display, among a plurality of recognized traffic signals. When there is an inconsistency in traffic signal displays identified between a plurality of integrated traffic signals, the system determines a first estimated traffic signal display of the forward traffic signal, based on the first evaluation value for each traffic signal.

  • Patent number: 11341866
    Abstract: System, methods, and other embodiments described herein relate to improving the training of a driver during automated driving system mode. In one embodiment, a method includes generating, in association with a vehicle takeover and a maneuver by the driver, an automated motion plan associated with the maneuver. The method also includes determining if a difference parameter satisfies a threshold, wherein the difference parameter indicates a disparity between the maneuver by the driver in relation to the automated motion plan associated with the maneuver. The method also includes notifying, if the difference parameter does not satisfy the threshold, the driver that the vehicle takeover and the maneuver by the driver were unnecessary.

  • Publication number: 20220121198
    Abstract: An autonomous driving control device is capable of starting an autonomous driving control without an operation of a driver and reducing a possibility that the driver can not start manual driving. An autonomous driving control is switched to manual driving when a determination section determines that the amount of operation by the driver is equal to or greater than a first threshold, before a predetermined time elapses since the autonomous driving control is automatically started. An autonomous driving control is switched to a manual driving when the determination section determines that the amount of operation by the driver is equal to or greater than a second threshold that is greater than the first threshold, after the predetermined time elapses.
