  • Publication number: 20240400064
    Abstract: A prediction accuracy evaluation method is executed by a computer. The prediction accuracy evaluation method includes a process of acquiring detection information. The detection information indicates a detected position, a detected velocity, an error range of the detected position, and an error range of the detected velocity of an obstacle detected by using a sensor mounted on a moving body. The prediction accuracy evaluation method further includes: a predicted distribution generation process that generates a predicted distribution of a position of the obstacle at a second time later than a first time, based on first detection information that is the detection information at the first time; and a prediction abnormality determination process that determines whether or not the predicted distribution is abnormal based on the predicted distribution and a second detected position that is the detected position of the obstacle at the second time.

  • Publication number: 20240317220
    Abstract: A vehicle control system generates a target trajectory and controls a vehicle to follow the target trajectory. Blind spot information indicates a blind spot region present in front of the vehicle. Under assumption that a first object appears at a first position in front of the vehicle, decelerating the vehicle with a first deceleration cannot avoid a collision between the first object and the vehicle. A deceleration map, which is prepared in advance, indicates at least a collision region consisting of the first position. The vehicle control system recognizes, based on the deceleration map, the collision region under assumption that the vehicle reaches a future position on the target trajectory. When the collision region and the blind spot region overlap each other, the vehicle control system modifies the target trajectory so that the collision region and the blind spot region do not overlap each other.

  • Publication number: 20240253650
    Abstract: A vehicle control system for controlling a vehicle is configured to perform automated driving by switching between a plurality of automated driving modes. The plurality of automated driving modes include: a first automated driving mode that does not require a driving operation by a human; and a second automated driving mode that requests an operation or monitoring by a human as necessary. In the first automated driving mode, the vehicle control system determines that there is human intervention when an operation state of an operating member operable by a human satisfies a first condition. In the second automated driving mode, the vehicle control system determines that there is human intervention when the operation state of the operating member satisfies a second condition. The first condition is less likely to be satisfied than the second condition.

  • Publication number: 20240208538
    Abstract: A vehicle control system includes one or more processors configured to execute automated driving control that controls automated driving of a vehicle. The automated driving control includes risk avoidance control that avoids a collision with a target around the vehicle. When a notification representing a risk level around the vehicle is received from an operator during the automated driving control, the one or more processors are configured to relax an activation condition of the risk avoidance control or increase a control amount in the risk avoidance control as the risk level becomes higher.

  • Publication number: 20240208550
    Abstract: The vehicle controller of the present disclosure acquires a preset operation route, and causes the vehicle to travel along the preset operation route in one of an autonomous driving mode and a manual driving mode. The autonomous driving mode is a mode in which the vehicle is operated by autonomous driving. The manual driving mode is a mode in which the vehicle is operated by manual driving in which at least steering is manually performed. The vehicle controller of the present disclosure generates steering torque in a direction of returning the vehicle to the preset operation route in response to detection of steering toward a road deviating from the preset operation route during operation in the manual driving mode.

  • Patent number: 12018954
    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.

  • Patent number: 11938952
    Abstract: A traveling trajectory estimation system obtains traveling record information indicating a past traveling record of a vehicle, and characteristic object position information indicating the installation position of a characteristic object, and performs a vehicle position estimation process to estimate an object vehicle position at an object time, based on the traveling record information and the characteristic object position information. In the vehicle position estimation process, not only a time previous to the object time, but also a time subsequent to the object time, is used as a reference time. The traveling trajectory estimation system sets each of a plurality of successive times as the object time, and performs the vehicle position estimation process, to estimate the object vehicle positions at the respective times, and determines a collection of the estimated object vehicle positions as a traveling trajectory of the vehicle.
