Abstract: Embodiments generally relate to device and methods for detecting force. A force sensor may include a sense die, a substrate, one or more sense elements supported by the sense die, one or more electrical contacts located on the sense die and electrically coupled to electrical traces on the substrate, and an actuation element configured to transmit a force to the sense die. The width of the actuation element may be less than the distance between the one or more electrical contacts. In some embodiments, the actuation element may include a thin wedge/plate configured to interact with the sense die at a contact point. The thin wedge/plate may allow use of a smaller sense die and/or may allow closer placement of the one or more sense elements to the contact point and/or may prevent accidental contact with the one or more electrical contacts which may lead to a short circuit.

Abstract: A vehicle state estimation system and method uses an observer model to make cornering stiffness estimates from tire-based sensor data and vehicle-based sensor data throughout transient and non-transient operational maneuvers of a vehicle. A cornering stiffness identifier extracts transient-state cornering stiffness estimates from the cornering stiffness estimates made by the observer model and extracts from the transient-state cornering stiffness estimates an optimal transient-state cornering stiffness estimate having a substantially highest confidence measure for use by a vehicle control system.
