Abstract: Kalman filter based road grade estimation techniques use models of a longitudinal accelerometer, an angular pitch rate gyroscope, and a velocity sensor and their outputs, and fuses the sensor measurements to optimally estimate the road grade. The proposed Kalman filter formulation is unique in that it uses a mathematical model of the sensors where the gyroscope output is considered as the input and the combined accelerometer and velocity sensor output is considered as the output of the model whose states are to be estimated. By using this unique second-order state space model, a Kalman filter based estimation algorithm is developed to estimate road grade accurately in real-time. This estimated road grade is then being utilized by various vehicle efficiency and/or safety systems to improve vehicle efficiency and/or vehicle safety.

Abstract: A multi-functional coupler for one or more vehicle components includes a shank, a head connected to the shank, a connector carried by the shank, and a tool. The tool is carried by the head or shank spaced from the connector, and the tool has a fastener engaging portion by which a fastener may be moved to install or remove the fastener from a component. The coupler may be used to both coupled together two or more components, and to remove fasteners or other connections via the tool of the coupler. Conveniently, as the coupler is normally installed on the vehicle to couple together two or more vehicle components, the coupler is readily available to a user wanting to remove fasteners compatible/drivable with the tool of the coupler.
