A system that uses a map database as a predictive sensor and more specifically to a system and method of using a map database as a path predictive vehicle sensor or input with the additional ability to identify system related point of interests, or detect and internally correct for errors in the map database that are found during operation of the vehicle as well as preemptively identifying problematic errors in the database that may create false negatives, or sometimes false positives when combined with a warning system such as a form of a stability system, crash avoidance system, or crash warning system.

A system for predictive front lighting of a vehicle. The system includes at least two headlamps, at least two swivel mechanisms and a controller. The first and second headlamps project a beam pattern for illumination of the vehicle path. The controller receives vehicle position data, as well as, data regarding a most likely path and a secondary path of the vehicle. The controller then calculates the desired swivel angle of the headlamps based on the most likely path of the vehicle and the secondary path of the vehicle, and the swivel mechanisms respectively manipulate each of the headlamps to accordingly change alignment of the headlamps based on the swivel angle for each of the of the headlamps.
摘要:
The present invention provides a system and method of selecting a most likely path of a vehicle from a list of candidate paths. If only one candidate path exists, that path is identified as the most likely path. For multiple candidate paths, cost functions determine the weight of various parameters associated with each candidate. The parameters may include lane information, the vehicle speed, the vehicle travel direction, the lateral speed of the vehicle, the state of various signals, such as the turn signals. From the various weights determined by the cost functions, the candidate path with the highest confidence level is determined to be the most likely path.

A management system for a vehicle including a database adapted to store a plurality of records, wherein each of the records represents an output of a vehicle system and a processor in communication with the database and the vehicle system, wherein the processor receives the output of the vehicle system, analyzes the output, manages the records in the database in response to the analysis of the output, and controls the transmission of the output to a driver of the vehicle in response to at least one of the analysis of the output of the vehicle system and the records in the database.
摘要:
A method for determining whether a target vehicle in front of a host vehicle intends to change lanes using radar data and image data is disclosed, comprising the steps of processing the image data to detect the boundaries of the lane of the host vehicle; estimating a ground plane by determining a projected vanishing point of the detected lane boundaries; using a camera projection matrix to map the target vehicle from the radar data to image coordinates; and determining lane change intentions of the target vehicle based on a moving trajectory and an appearance change of the target vehicle. Determining lane change intentions based on a moving trajectory of the target vehicle is based on vehicle motion trajectory relative to the center of the lane such that the relative distance of the target vehicle from the center of the lane follows a predetermined trend. Determining lane change intentions based on an appearance change of the target vehicle is based on a template that tracks changes to the appearance of the rear part of the target vehicle due to rotation.

A system for predictive front lighting of a vehicle. The system includes a first and second headlamps, a first and second swivel mechanisms and a controller. The first and second headlamps project a beam pattern for illumination of the vehicle path. The controller receives vehicle position data, for example from a GPS system, and accesses a map database to identify a map location of the vehicle. The controller further analyzes the map to determine a most likely path of the vehicle based on the map location and other vehicle heading parameters. The controller then calculates the desired swivel angle of the first and second headlamps based on the most likely path of the vehicle, and the first and second swivel mechanisms manipulate the first and second headlamps to accordingly change the swivel angle of the headlamps.

A drive alert system and method for a host vehicle having an adaptive cruise control system. The driver alert system determines if the adaptive cruise control system is on or off and adjusts the factors for determining braking capability and delay, when determining driver alert situations. The system and method also evaluates a vehicle situation relative to a phase plane, having axes of relative speed and relative acceleration of the host vehicle relative to a preceding vehicle, and compares the vehicle situation to a threshold for a particular region of the phase plane.

An in-vehicle system and method for warning a driver of upcoming curves in a road including. In general, a vehicle positioning module determines the vehicle's position in a global positioning system and a map matching module determines the vehicle's position on a map based on the position in the global positioning system. A look ahead module looks ahead on the map for a curve, determines a candidate list of probable driving paths through the curve, and from this candidate list determines the most likely path of the vehicle around the curve. A warning module then assesses the threat the upcoming curve poses to the vehicle.

摘要:
A vehicle having an adaptive cruise control system with a method for determining an optimum deceleration amount for a host vehicle when approaching an in-path vehicle. This includes determining a relative speed between the vehicles, as well as estimating the deceleration for each. An optimal deceleration estimator calculates the instantaneous amount of deceleration needed to match the host vehicle speed with the in-path vehicle speed at a desired future range between the host vehicle and the in-path vehicle. A deceleration limiter can then use the output from the deceleration estimator to determine an optimum deceleration for the vehicle systems to initiate.
