  • Patent number: 11964676
    Abstract: A control command is provided to a vehicle control module that identifies one or more vehicle actions to be performed by the vehicle control module to control a position of an autonomous vehicle (AV) with respect to an external environment. Whether one or more conditions pertaining to the position of the AV with respect to the external environment are satisfied is determined. Responsive to determining that the one or more conditions pertaining to the position of the AV with respect to the external environment are satisfied, a first instruction is provide to the vehicle control module that permits the vehicle control module to deviate from the one or more vehicle actions identified in the control command and to perform an energy saving action with respect to the AV.

  • Patent number: 11964656
    Abstract: A travel control device assists automatic traveling of a vehicle by controlling a target vehicle speed, which is a target value of an actual vehicle speed, when making the vehicle travel to a target point. The travel control device includes a setting unit for executing a setting process for setting the course of the target vehicle speed until the vehicle reaches the target point, based on the actual vehicle speed and the target point. If a request to change the vehicle speed occurs during execution of the automatic traveling and the actual vehicle speed is changed based on the request, the setting unit executes a resetting process for resetting the course of the target vehicle speed, based on the actual vehicle speed when the request is canceled and a remaining distance from a position of the vehicle when the request is canceled to the target point.

  • Patent number: 11945454
    Abstract: Systems and methods for dynamically limiting the road speed of a vehicle are provided herein. The method includes limiting the speed of the vehicle to a predetermined first speed under normal operating conditions. The method further includes selectively engaging an override condition for an activation interval responsive to an operator generated input. The override condition may be limited to a determined number of times in an activation assessment interval. During an activation interval of the override condition, the vehicle can exceed the predetermined first speed by a specified offset that defines a second speed greater than the first speed. The activation interval may be a period of time or a distance. The override condition is not available when the number of activations in the activation assessment interval exceeds a threshold value. The activation assessment interval may be defined by a period of time, a distance, an event or action, etc.

Before the vehicle passes through an inflection point of a curvature of a target trajectory, the processor sets a first reference point before the inflection point. After the vehicle passes through the inflection point, the processor sets a second reference point at a position where a second distance from a current position of the vehicle after the vehicle passes through the inflection point to the second reference point is longer than a first distance from a current position of the vehicle before the vehicle passes through the inflection point to the first reference point when compared under travel conditions identical in a vehicle speed, an acceleration rate, a deceleration rate, or a steering angle. The processor sets a target steering angle based on the curvature of an arc passing through the current position and the first reference point or the second reference point.

  • Patent number: 11802969
    Abstract: Techniques are discussed for controlling a vehicle, such as an autonomous vehicle, based on occluded areas in an environment. An occluded area can represent areas where sensors of the vehicle are unable to sense portions of the environment due to obstruction by another object. An occlusion grid representing the occluded area can be stored as map data or can be dynamically generated. An occlusion grid can include occlusion fields, which represent discrete two- or three-dimensional areas of driveable environment. An occlusion field can indicate an occlusion state and an occupancy state, determined using LIDAR data and/or image data captured by the vehicle. An occupancy state of an occlusion field can be determined by ray casting LIDAR data or by projecting an occlusion field into segmented image data. The vehicle can be controlled to traverse the environment when a sufficient portion of the occlusion grid is visible and unoccupied.

In arrangements with inclined roadways, resuming a movement is problematic in that doing so has hitherto only been possible with a limited arrangement of the roadways and/or with highly dimensioned drives. The novel method provides for moving a driverless transport vehicle on an inclined transport roadway, wherein the steering drives are actuated on the basis of the detected inclination direction in order to move the vehicle such that the transport vehicle is moved transversely to the inclination direction. After a specified minimum speed of the transport vehicle transversely to the inclination direction is reached, the steering drives are adjusted such that the transport vehicle continues to move in the inclination direction.

  • Patent number: 11505192
    Abstract: A vehicle control apparatus includes a controller configured to perform creep traveling control in which a vehicle is caused to travel regardless of an accelerator operation. When one or both of front wheels or one or both of rear wheels of the vehicle are determined as having moved onto a step by the controller after the creep traveling control starts, the controller causes a target vehicle speed of the creep traveling control to be lower than a first target vehicle speed until the remaining wheels out of the front wheels and the rear wheels are determined as having moved onto the step. The first target vehicle speed is equal to the target vehicle speed having been set before a time when the one or both of the front wheels or the one or both of the rear wheels are determined as having moved onto the step.
