Embodiment Construction

[0015] refer to Figure 1A , Figure 1B and Figure 1C , showing mutually perpendicular views of top, front and side profiles of a motor vehicle according to the invention. Figure 1 depicts the general orientation of angular and linear motion as measured by one or more inertial sensors. The orientation and rotation components that can be measured by inertial sensors in vehicle applications include linear components 2, 4, 6 and rotational components 8, 10, 12, referred to here as X (longitudinal), Y (lateral), and Z (vertical), respectively Orthogonal components and roll, pitch, and yaw rotational components. These sensors can be further offset to take measurements directly between the directions shown. A variety of sensors may be implemented to measure the linear and rotational components of acceleration and / or velocity affecting the vehicle during operation. Typically, a linear accelerometer is used to measure linear acceleration, and an angular rate sensor or two or more...

Abstract

The present invention provides an improved method and system for compensation of inertial sensors. In one implementation a modified moving average is applied to provide dynamic offset compensation for an inertial sensor output that is calculated when a vehicle is in motion.

Description

technical field [0001] The present invention relates to a method of compensation for rate sensing devices, and more particularly to methods and systems for offset and compensation of angular and linear inertial sensors, primarily in self-propelled In the vehicle (automotive vehicle). Background technique [0002] Inertial sensors include several classes of sensors that measure angular velocity and linear acceleration, with varying levels of accuracy and range. In the automotive field in particular, inertial sensors have recently become more widespread and used in various applications to improve the safety, performance and comfort of self-propelled vehicles. Existing applications of inertial sensors in automobiles range from being used as advanced anti-lock braking systems (ABS), electronic stability programs (ESP) and other forms of automatic yaw and roll control (these other forms of automatic yaw and roll control Measurements of the longitudinal velocity and acceleration...
