It is determined whether the vehicle is in a stationary state by analyzing the acceleration measurement. If the vehicle is not in the stationary state, the inclination angle of a road on which the vehicle is traveling is calculated using a plurality of three-dimensional shape points included in the RGI data. A gravity acceleration component is compensated for from the acceleration measurement using the road inclination angle. The velocity of the vehicle is calculated using the compensated acceleration measurement.

摘要： Disclosed are an apparatus and a method for measuring the speed of a moving body using an accelerometer. A value of earth's gravitational acceleration component is detected from the measurements from the accelerometer and is removed from the acceleration value. Then, the acceleration value, after removal of the earth's gravitational acceleration component, is used to obtain the speed of the moving body. The earth's gravitational acceleration component is detected using a movement average at a point of time when the speed of the moving body is to be measured. By using the magnitude of a difference between a value obtained by removing an x-axis movement average from an x-axis measurement from the two-axis accelerometer and another value obtained by removing a y-axis movement average from a y-axis measurement from the two-axis accelerometer, it is possible to regulate a window for calculating the movement average and a weight value to each of the measurements included in the window. The present invention saves cost by reducing the number of expensive gyroscopes in implementing a speed measuring apparatus for vehicles. In addition, the speed measuring apparatus designed according to the present invention is superior to that designed according to the prior art in performance and improves the accuracy of position estimation in position estimation apparatuses for vehicles.

摘要： An apparatus and method for estimating a step length of a user are provided. The apparatus and method use a step length estimation algorithm, e.g. a step length estimation parameter coefficient, according to a movement state of a user, i.e. whether the movement state is a walking state or a running state. The movement state of the user is determined on the basis of an acceleration variance value of an acceleration signal output from an accelerometer. Accordingly, the apparatus and method prevent errors in step length determinations.

A controller determines a magnitude of a swinging motion of the portable terminal by using at least one of the detected acceleration and angular velocity, determines that the portable terminal makes the swinging motion when the magnitude of the swinging motion is equal to or greater than a predetermined value, determines a carrying position of the portable terminal in the pedestrian's body by using at least one of the detected acceleration and angular velocity, and estimates a step length of the pedestrian according to the determined carrying position of the portable terminal.
