Path-based approach to passive vehicle entry is provided. A vehicle receives messages over a first protocol from a mobile device, each of the messages indicating a heading of the mobile device and a current location of the mobile device. The vehicle and the mobile device pair responsive to the current location of the mobile device being within a first threshold distance to the vehicle. Responsive to the heading indicating that the mobile device is headed towards the vehicle and the current location of the mobile device being within a second threshold distance from the vehicle, the second threshold distance being closer to the vehicle than the first threshold distance, the vehicle activates one or more second transceivers to perform time of flight distance measurement between the vehicle and the mobile device to obtain more precise positional accuracy, and otherwise maintains the one or more second transceivers in a deactivated mode.

Path-based detection of user approach for passive entry

A lane departure warning system has a trailer detector for detecting that a trailer is attached to a vehicle, a lane boundary detector for detecting a position of a lane boundary on a roadway over which the vehicle is travelling, and an information processor including a calibrator for generating calibration parameters used in determining an unintended lane departure event with respect to the lane boundary. The information processor initiates a process for allowing an operator to provide trailer width information when the trailer detector indicates that the vehicle is towing a trailer. The lane departure warning system also includes a sensor for detecting a hitch angle between the vehicle and the trailer. A controller determines a lateral offset of the trailer relative to the vehicle based on the hitch angle and a length of the trailer for generating a warning signal when the lateral offset crosses the lane boundary.

Trailer lane departure warning system

A lane departure warning system has a trailer detector for detecting that a trailer is attached to a vehicle, a lane boundary detector for detecting a position of a lane boundary on a roadway over which the vehicle is travelling, and an information processor including a calibrator for generating calibration parameters used in determining an unintended lane departure event with respect to the lane boundary. The information processor initiates a process for allowing a vehicle operator to provide trailer width information when the trailer detector indicates that the vehicle has the trailer attached thereto. The trailer width information is used by the information processor for generating the calibration parameters as a function of a width of the trailer.
