Abstract
A pedal system includes a user interface, e.g., a pedal for contacting by a driver of a vehicle, a force sensor, and a force transfer member between the user interface and the force sensor. A force applied to the user interface is detected and measured by the force sensor. One or more membranes, e.g., two membranes, are arranged at an outer surface of the force transfer member to decouple off-center loading and non-uniform forces, e.g., resulting from off-center force application at the user interface.
Claims15
A pedal system comprising:
- a user interface configured to receive an application of force;
- a force sensor spaced from the user interface;
- a force transfer member extending, in an axial direction, between a first end coupled to the user interface and a second end coupled to the force sensor, the force transfer member configured to transfer a force applied at the user interface to the force sensor;
- a housing at least partially surrounding the force transfer member;
- a first annular membrane disposed within the housing and circumscribing the force transfer member proximate the first end of the force transfer member;
- and
- a second annular membrane disposed within the housing and circumscribing the force transfer member proximate the second end of the force transfer member.

A system comprising:
- a user interface configured to receive an application of force;
- a micro strain gauge sensor spaced from the user interface;
- an elongate member coupled at a first end to the user interface and coupled at a second end to the micro strain gauge sensor and configured to transfer a force applied at the user interface to the micro strain gauge sensor;
- a housing at least partially surrounding the elongate member, the housing having an inner surface spaced radially from an outer surface of the elongate member;
- and
- a membrane circumscribing the elongate member and positioned between the inner surface of the housing and the outer surface of the elongate member.
