Embodiment Construction

[0043] figure 1 The vehicle 11 is depicted in perspective with a vehicle coordinate system whose origin is at the center of gravity of the vehicle 11 . The x-axis of the coordinate system is aligned with the longitudinal axis of the vehicle 11 in the forward direction of vehicle motion, and the y-axis of the coordinate system is aligned with the transverse axis of the vehicle 11 . If the vehicle 11 is empty, ie if there are no passengers or other loads within the vehicle, the x- and y-axes are aligned parallel to the ground plane on which the vehicle 11 is located. Furthermore, for an empty vehicle 11, the z-axis of the coordinate system is aligned perpendicular to the ground plane.

[0044] To describe the orientation of the vehicle 11, the roll angle Φ, the pitch angle θ and the yaw angle Ψ are generally used. Such as figure 1 As shown, the roll angle Φ describes the rotation of the vehicle about the x-axis, the pitch angle θ describes the rotation about the y-axis, and t...

Abstract

The invention provides a method and a system for localizing an occupant within a vehicle. A computer implemented method for localizing an occupant within a vehicle is provided. According to the method, it is identified whether at least one occupant is present within the vehicle based on a signal of an ultrasonic sensor, and information is determined regarding inclination of the vehicle based on atleast one signal of an inclination sensor. Based on the information regarding inclination of the vehicle it is determined whether an occupant is present in one of a plurality of predefined sections of the vehicle if the presence of at least one occupant within the vehicle is identified.

Description

technical field [0001] The present disclosure relates to methods and systems for locating passengers within a vehicle. Background technique [0002] For certain automotive applications, a valuable input is reliable information about the presence or absence of passengers in the cabin of the vehicle. This is especially true for functions and systems that are available in the parked state of the vehicle. Furthermore, for automotive applications, it may also be valuable information whether a passenger actually enters or exits a certain seat of the vehicle after the door has been opened. [0003] In modern vehicles, seat belt reminders, cameras or similar systems can be used to locate occupants in the vehicle. However, many vehicles do not have seat belt reminders on the rear seats. In addition, the vehicle's seat belt reminder, camera, and and many other security systems may be turned off. [0004] Therefore, there is a need to provide a method and system capable of locatin...
