Vehicle control method and apparatus, electronic device and storage medium
The present disclosure relates to adaptive cruise control in the field of automatic driving, and discloses a vehicle control method, an apparatus, an electronic device and a storage medium. A specific implementation is: firstly, determining a target travelling scenario according to real-time monitoring data upon fulfilment of a preset update condition; then, determining a target time headway according to the target travelling scenario, where the target time headway is used to dynamically adjust a relative motion state between an host vehicle and a surrounding vehicle; and finally, controlling a vehicle according to the target time headway. It solves the problem of the prior art in overemphasizing the state of the vehicle ahead for automatic driving control while overlooking the perception of the driver or passenger of the host vehicle in the travelling scenario can prompt the driver to manually intervene, compromising the experience of the automatic driving.
Adaptation of passage between two vehicles
An intention of a road user to traverse a passage between a first vehicle and a second vehicle is determined. A required width of the passage is determined based on a nature of the road user. A current width of the passage is determined. Upon determining the current width of the passage is less than the required width of the passage, a drive of at least one of the first vehicle or the second vehicle is actuated to increase the current width of the passage at least to the required width of the passage.
Vehicle control method and vehicle control device
A vehicle control method for controlling a vehicle using a vehicle control apparatus includes: a sensor configured to detect a state outside a subject vehicle; and a control device. The vehicle control method includes: executing control of recovering a travel trajectory of the subject vehicle to a target trajectory, as ordinary control, by giving a steering amount in a lateral direction with respect to a travel lane of the subject vehicle; using detection data of the sensor to determine whether or not another vehicle is traveling in an adjacent lane to the travel lane of the subject vehicle; and when determining that the other vehicle is traveling in the adjacent lane ahead of the subject vehicle, increasing a response of the steering amount to a higher response than that in the ordinary control, before the subject vehicle passes the other vehicle.
VEHICULAR CONTROL SYSTEM WITH ENHANCED LANE CENTERING
A vehicular control system includes a camera that captures image data. The system includes an electronic control unit (ECU) for processing image data captured by the camera. The ECU, via processing by an image processor of image data captured by the camera, determines lane information of a traffic lane along a road being traveled by the equipped vehicle. The ECU determines a lane quality value that represents a confidence in the determined lane information. When the lane quality value exceeds a threshold value, and based at least in part on the determined lane information, the ECU provides a steering command to a steering system of the equipped vehicle to adjust a heading of the equipped vehicle to center the equipped vehicle within the traffic lane of the road being traveled by the equipped vehicle.
SYSTEM AND METHOD FOR PROVIDING IN-VEHICLE EMERGENCY VEHICLE DETECTION AND POSITIONAL ALERTS
A system for providing in-vehicle emergency vehicle detection and positional alerts, including: a camera configured to obtain an image of surroundings of an ego vehicle; an emergency vehicle recognition and localization module operable for segmenting an emergency vehicle from the image of the surroundings in order to detect and locate the emergency vehicle relative to the ego vehicle; a microphone configured to obtain an auditory signal from the surroundings of the ego vehicle; a siren detection and directional positioning module operable for discriminating an emergency vehicle siren from the auditory signal from the surroundings in order to detect and locate the emergency vehicle relative to the ego vehicle; and one or more of a visual alert, an audible alert, and a haptic alert operable for alerting a driver of the ego vehicle to a presence and the location of the emergency vehicle.
Vehicle acoustic-based emergency vehicle detection
An emergency vehicle detection system for a vehicle includes a plurality of camera assemblies having a camera and at least one microphone. At least one processor processes image data captured by the cameras, and processes outputs of the microphones. The at least one processor processes the outputs of the microphones to detect a sound source indicative of a siren emanating from an emergency vehicle exterior of the equipped vehicle, and to determine the direction of the detected sound source. Responsive to detection of the sound source and determination of the direction of the detected sound source, the at least one processor processes image data captured by at least one of the cameras that has its field of view encompassing the detected sound source to confirm that the detected sound source is a siren emanating from an emergency vehicle.
Method for optimizing three-point turn of autonomous driving vehicles
In one embodiment, it is determined that a speed of an autonomous driving vehicle (ADV) is below a predetermined speed threshold during a current turn section of a three-point turn, where the three-point turn includes at least three turn sections. In response, detecting an obstacle within a predetermined proximity of the ADV, determining a type of obstacle. An amount of time during which the speed of the ADV remains below the predetermined speed threshold is determined. It is determined whether the amount of time is greater than a time threshold corresponding to the type of the obstacle. If the amount of time is greater than the time threshold, the current turn section is ended and a next turn section is started.
Systems and methods for navigating a vehicle
Systems and methods are provided for vehicle navigation. In one implementation, a system may comprise an interface to obtain sensing data of an environment of the host vehicle. The processing device may be configured to determine a planned navigational action; identify, a target vehicle in the environment of the host vehicle; predict a distance between the host vehicle and the target vehicle if the planned navigational action was taken; determine a current host vehicle stopping distance based on a braking capability, acceleration capability, and speed of the host vehicle; determine a current target vehicle braking distance based on a speed and braking capability of the target vehicle; and implement the planned navigational action when the predicted distance of the planned navigational action is greater than a minimum safe longitudinal distance calculated based on the current host vehicle stopping distance and the current target vehicle braking distance.
Method for detecting inconsistencies in the outputs of perception systems of autonomous vehicles
A system and method for the detection of inconsistencies in perception systems of autonomous vehicles is described. The system receives the observations of objects in the surrounding environment from one or more sensors or perception systems of an automated vehicle. At actual time, the system estimates the consistency of the currently observed elements of the perception system according to the previous inputs received. This consistency is decided by calculating the boundaries of possible states of the previously observed elements, based on the received information and on assumptions.
DRIVING ASSISTANCE DEVICE AND DRIVING ASSISTANCE METHOD
A driving assistance device includes a determination unit configured to, in a case where a preceding vehicle located in front of a vehicle in a stopped state starts, determine whether an object is located inside a specified area that is a predetermined area in front of the vehicle, and a driving assistance unit configured to maintain the stopped state of the vehicle in a case where an object is located inside the specified area in a case where the preceding vehicle starts.
