The control system is configured to apply a first braking force to the ground engaging propulsion structure that is based on the determined output of the drive arrangement.
Automatic Emergency Braking for a Path-Crossing Target
Techniques are described that enable automatic emergency braking (AEB) for a path-crossing target when a collision between a host vehicle and the target that is deemed imminent. Based on whether an acceleration of the host vehicle is above a threshold. Based on the acceleration, and, optionally, a location of the target relative to a crossing path (e.g., whether a portion of the target is within a suppression zone), an AEB system of the host vehicle is either activated or not activated, for example, suppressed. This suppression of the AEB system may include gating or nulling an AEB activation signal to prevent an emergency braking event. By managing the AEB system in a path-crossing scenario, many common false-positive AEB events (warnings, alerts, and/or braking) may be avoided. Furthermore, intentional vehicle maneuvers that comply with normal driving etiquette or rules can still be allowed for operator and passenger comfort, without risking safety.
METHODS AND SYSTEMS FOR MONITORING VEHICLE MOTION WITH DRIVER SAFETY ALERTS
Methods, systems, and computer program products for navigating a vehicle are disclosed. The methods include extracting lane segment data associated with lane segments of a vector map that are within a region of interest, and analyzing the lane segment data and a heading of the vehicle to determine whether motion of the vehicle satisfies a condition. The condition can be associated with (i) an association between the heading of the vehicle and a direction of travel of a lane that corresponds to the current location of the vehicle and/or (ii) a minimum stopping distance to an imminent traffic control measure in the lane that corresponds to the current location of the vehicle. When the motion does not satisfy the condition, the methods include causing the vehicle to perform a motion correction.
Side collision risk estimation system for a vehicle
A side collision risk estimation system for a vehicle comprises a speed sensor, a road line markers detector, a movement sensor, an object detector, and a controller. The controller is configured to estimate: the current speed of the vehicle, a heading of the adjacent road line ahead of the vehicle, a heading of the vehicle, a compensated heading of the vehicle, a predicted lateral change position of the vehicle, a heading of a target vehicle relative to the vehicle, the current speed of the target vehicle, the current lateral distance between the vehicles, the heading of the adjacent road line ahead of the target vehicle, a compensated relative heading of the target vehicle, a predicted lateral change position of the target vehicle, a predicted lateral distance over time between the vehicles, and a side collision risk over time from the predicted lateral distance between the vehicles.
Method and device for facilitating manual operation of a vehicle
A processing platform may obtain sensor data associated with a vehicle and manual input data associated with the vehicle. The processing platform may determine, based on the sensor data, automated control information. The processing platform may determine, based on the sensor data and the manual input data, a parameter associated with the vehicle. The processing platform may determine, based on the automated control information, a control rating associated with the parameter. The processing platform may determine whether the control rating satisfies a threshold for a period of time. The processing platform may cause, based on determining that the control rating satisfies the threshold for the period of time, at least one action to be performed.
Enhanced object detection and response
A computer is programmed to identify a turning center defined by a turning radius of the vehicle and a heading angle of the vehicle, identify a boundary circle having a center defined by the turning center and a radius extending to a location of a detected object, identify coordinates for each of a plurality of vertices of an external contour of the vehicle, the external contour defining a plurality of line segments, each line segment connecting two of the vertices, upon identifying at least one line segment that intersects the boundary circle, identify at least one of an object distance or an intersection time between the object and the vehicle, and actuate at least one of a steering or a brake to avoid the object when the object distance is below a distance threshold or the intersection time is below a time threshold.
Method and system for dynamically generating a secure navigation path for navigation of autonomous vehicle
Disclosed herein is a method and system for dynamically generating a secure navigation path for navigation of an autonomous vehicle. The method comprises detecting disproportional acceleration of the autonomous vehicle when the autonomous vehicle is navigating from a source point to a destination point based on a predefined trajectory plan. The method comprises determining direction values of the autonomous vehicle for reaching a secure path point in the predefined trajectory plan. Based on the determined direction values, distance values are determined. The method includes detecting position of the secure path point for navigation of the autonomous vehicle based on the determined direction values and the distance values. The present disclosure uses secure path point to realign the autonomous vehicle in the predefined trajectory plan to overcome the disproportional acceleration of the autonomous vehicle due to narrow roads, upward slope, or downward slope.
VEHICLE TRAVEL CONTROL METHOD AND APPARATUS
The present disclosure provides a vehicle travel control method and apparatus. A specific implementation lies in: acquiring a distance between a vehicle and a first intersection, where the first intersection is an intersection for the vehicle to go across on a first road which the vehicle is currently on; acquiring, on a determination that the distance is less than or equal to a preset distance, intersection information of the first intersection and travelling information of the vehicle, where the intersection information includes lane information of at least two lanes on the first road; determining, according to the intersection information and the travelling information, a target weight of each of the lanes for the vehicle to travel into; and determining, according to the target weight of each of the lanes for the vehicle to travel into, an intended travel route of the vehicle.
DETERMINATION OF DRIVING DIRECTION
A method for determining a driving direction is disclosed. The method includes: obtaining a driving route for a vehicle; determining a target intersection in the driving route, and obtaining border information about intersection range borders defining a range of the target intersection; predicting, based on the driving route and the border information corresponding to the target intersection, a first direction for the vehicle to enter the target intersection, a second direction for the vehicle to travel within the target intersection, and a third direction for the vehicle to leave the target intersection; and determining, based on the first direction, the second direction, and the third direction, a target driving direction for the vehicle to pass the target intersection.
SYSTEMS AND METHODS FOR DETERMINING PASSAGE STATUS OF A TRAIN AT A RAILROAD CROSSING
This disclosure is generally directed to systems and methods for determining a passage status of a train through a railroad crossing. In an example method, a railroad crossing status detector system provided in a vehicle may determine that a train is approaching the railroad crossing. The determination is made by evaluating a first detection signal received from a first train detection apparatus located on one side of the railroad crossing. The railroad crossing status detector system may then evaluate a second detection signal received from a second train detection apparatus located on the other side of the railroad crossing and determine that the train has traveled past the railroad crossing. The system may also evaluate one or both detection signals to determine whether the train is currently located at the railroad crossing or is backing up after traveling at least partway across the railroad crossing.
