摘要:
Methods, systems, and vehicles are provided for localizing a vehicle. A sensor is configured to detect an object disposed in a generally upward direction from the vehicle while the vehicle is travelling. A processor is coupled to the sensor. The processor is configured to correlate the object with information from a map database, thereby generating a correlation, and determine a geographic location of the vehicle based on the correlation.
摘要:
A method of associating targets from at least two object detection systems. An initial prior correspondence matrix is generated based on prior target data from a first object detection system and a second object detection system. Targets are identified in a first field-of-view of the first object detection system based on a current time step. Targets are identified in a second field-of-view of the second object detection system based on the current time step. The prior correspondence matrix is adjusted based on respective targets entering and leaving the respective fields-of-view. A posterior correspondence matrix is generated as a function of the adjusted prior correspondence matrix. A correspondence is identified in the posterior correspondence matrix between a respective target of the first object detection system and a respective target of the second object detection system.
摘要:
A method for selecting an anchor lane for tracking in a vehicle lane tracking system. Digital map data and leading vehicle trajectory data are used to predict lane information ahead of a vehicle. Left and right lane boundary markers are also detected, where available, using a vision system. The lane marker data from the vision system is combined with the lane information from the digital map data and the leading vehicle trajectory data in a lane curvature fusion calculation. The left and right lane marker data from the vision system are also evaluated for conditions such as parallelism and sudden jumps in offsets, while considering the presence of entrance or exit lanes as indicated by the map data. An anchor lane for tracking is selected based on the evaluation of the vision system data, using either the fused curvature calculation or the digital map and leading vehicle trajectory data.

A method to selectively prevent a vehicle from resuming a vehicle set speed stored in memory of a cruise control system includes monitoring a vehicle speed, determining that the vehicle speed indicates operation in a low speed range, determining a threshold slow zone maneuver based upon the vehicle speed substantially remaining in the low speed range through a predetermined duration, and inhibiting resumption of the vehicle set speed based upon the threshold slow zone maneuver.

Methods and system are provided for detecting attributes of a terrain surrounding a vehicle. The system includes at least one terrain sensor configured to generate data describing the terrain and a processor coupled to the at least one terrain sensor. The processor is configured to detect at least one attribute of the terrain based on data generated by the at least one terrain sensor and to adjust a handling behavior of the vehicle based on the at least one terrain attribute.

Disclosed herein is a method, system and storage medium for managing automated system events. The method includes identifying events that are a defined system event and associating the events identified with one of (a) events that cause an automated system to transition from an automatic cycle mode, the events having a fault type associated therewith; and (b) events that do not cause the automated system to transition from the automatic cycle mode. The method also includes generating a listing of the events identified with regard to the associating the events.
摘要:
A method and tools for virtually aligning object detection sensors on a vehicle without having to physically adjust the sensors. A sensor misalignment condition is detected during normal driving of a host vehicle by comparing different sensor readings to each other. At a vehicle service facility, the host vehicle is placed in an alignment target fixture, and alignment of all object detection sensors is compared to ground truth to determine alignment calibration parameters. Alignment calibration can be further refined by driving the host vehicle in a controlled environment following a leading vehicle. Final alignment calibration parameters are authorized and stored in system memory, and applications which use object detection data henceforth adjust the sensor readings according to the calibration parameters.
摘要:
A method for operating a cruise control system for a vehicle. The method can identify certain low speed environments, like parking lots, where usage of the cruise control system is usually inappropriate and can disable the system accordingly. According to one embodiment, a full speed range adaptive (FSRA) cruise control system compares a steering wheel position to a steering wheel threshold to determine if the vehicle is operating in an inappropriate low speed environment and, if so, disables the cruise control system accordingly.

A safety system is provided for use in a first vehicle at a first location. The safety system includes a position unit configured to determine the first location; a sensor group configured to detect an opening of the enclosure; a controller coupled to the position unit and the sensor group, the controller configured to generate a warning message including the first location when the opening of the enclosure is detected; and a transmitter coupled to the controller and configured to transmit the warning message.
