Abstract
A vehicle remote function system is provided for use in effectuating vehicle operations based on movement of a fob relative to a vehicle. The system may include a controller for determining locations of the fob within zones proximate the vehicle based on ultra-wide band wireless signals transmitted between the antennas and the fob, the zones including a primary zone and secondary zones, each secondary zone at least partially within the primary zone. The controller may be configured to detect a movement of the fob between secondary zones and generate a control signal for use in effectuating a vehicle operation based on the movement detected. A method is also provided which may include transmitting ultra-wide band wireless signals between the fob and the antennas, detecting a movement of the fob between secondary zones, and generating a control signal for use in effectuating a vehicle operation based on the movement detected.
