  • Patent number: 11276304
    Abstract: System, methods, and other embodiments described herein relate to dynamically determining an appropriate responsive action for a moving vehicle in accordance with local traffic regulations. In one embodiment, the disclosed system identifies a stationary vehicle in an environment of the subject vehicle based at least in part on information from a plurality of sensors disposed on the subject vehicle and classifies a type of the stationary vehicle as valid or abandoned based at least in part on the information from the plurality of sensors. A classification of valid indicates that a traffic regulation requires the subject vehicle to undertake a responsive action toward the stationary vehicle. The disclosed system obtains a local traffic regulation based on a location of the subject vehicle and modifies a trajectory of the subject vehicle based on the local traffic regulation when the type of the stationary vehicle is determined to be valid.

  • Patent number: 11011064
    Abstract: In one embodiment, example systems and methods related to vehicle platooning are provided. Vehicles are equipped with a vehicle platooning system that allows the vehicles to exchange messages related to vehicle platooning. When a following vehicle desires to follow a leading vehicle, the following vehicle sends a request to the leading vehicle, and the leading vehicle sends the following vehicle information such as its current speed. The following vehicle may then use the information, along with sensor data such as images of the rear of the leading vehicle, to follow the leading vehicle from a following distance. When the leading vehicle desires to change lanes, the leading vehicle sends a message to the following vehicle to determine if the following vehicle is able to change lanes. If the following vehicle determines that it can change lanes (i.e., the lane is clear from other vehicles or objects), the following vehicle can send a message to the leading vehicle indicating that it can change lanes.

  • Patent number: 10916134
    Abstract: System, methods, and other embodiments described herein relate to dynamically determining an appropriate responsive action for a moving vehicle that encounters a roadside pedestrian and stationary vehicle. In one embodiment the disclosed system identifies a stationary vehicle in an environment of a subject vehicle based at least in part on information from a plurality of sensors disposed on the subject vehicle and determines a classification for the stationary vehicle as valid or abandoned based at least in part on the information from the plurality of sensors. A classification of valid indicates that the subject vehicle is recommended to undertake an action relative to the stationary vehicle. The disclosed generates a score based at least in part on the classification, the score indicating a recommended trajectory modification for the subject vehicle, and modifies a trajectory of the subject vehicle based on score.

  • Patent number: 10906542
    Abstract: A driving system for a first vehicle, comprising one or more sensors configured to obtain proximity data for two or more vehicles proximate the first vehicle, and a processor in communication with the one or more sensors and programmed to classify the two or more proximate vehicles as a cluster in response to a heading angle of the two or more proximate vehicles being within a threshold-angle tolerance and a distance between each of the two or more proximal vehicles being within a threshold-distance tolerance based on the proximity data, to classify each of the two or more proximate vehicles in the cluster as either a trigger vehicle being closest to the first vehicle or a non-trigger vehicle, and activate a driver assistance function in response to a determination that the trigger vehicle is in an estimated-driving path of the first vehicle.

  • Patent number: 10239522
    Abstract: In an inter-vehicle control apparatus, a controller performs acceleration control of an own vehicle, based on an actual inter-vehicle physical quantity and a target inter-vehicle physical quantity. A limiter sets a limit value for a target jerk during the acceleration control. A detector detects an occurrence of at least one of: an event in which the inter-vehicle distance becomes discontinuously shorter; and an event in which a target inter-vehicle distance corresponding to the target inter-vehicle physical quantity becomes discontinuously longer. A determiner determines a risk of collision with the preceding vehicle, based on an operation state of the preceding vehicle in relation to the own vehicle. When at least one of the events is detected, the limiter sets the limit value to a value based on the risk of collision such that change in deceleration of the own vehicle is kept lower as the risk of collision decreases.

  • Patent number: 9694815
    Abstract: A vehicle driving control apparatus is provided for controlling an own vehicle to track a target vehicle. The vehicle driving control apparatus includes: (1) means for acquiring an actual relative speed of the target vehicle to the own vehicle; (2) means for setting a target acceleration of the own vehicle based on the product of a relative speed gain and the actual relative speed acquired by the acquiring means, the relative speed gain being normally set to a reference gain; (3) means for detecting occurrence of an event which causes the target acceleration set by the setting means to discontinuously change; and (4) means for correcting, upon detection of occurrence of the event by the detecting means, the relative speed gain so as to gradually increase the relative speed gain from a value that is less than the reference gain.

  • Patent number: 9588222
    Abstract: A preceding vehicle selection apparatus estimates a curvature of a road on which an own vehicle is traveling, detects an object ahead of the own vehicle, and determines a relative position in relation to the own vehicle. Based on the curvature and the relative position, an own vehicle lane probability instantaneous value is determined. This instantaneous value is a probability of the object ahead being present in the same vehicle lane as the own vehicle. By a filter calculation on the instantaneous value, an own vehicle lane probability is determined. Based on the own vehicle lane probability, a preceding vehicle is selected. An inter-vehicle time required for the own vehicle to reach a detection position of the object ahead is calculated. Based on the inter-vehicle time, characteristics of the filter calculation are changed such that an effect of the own vehicle lane instantaneous value increases as the inter-vehicle time decreases.
