Method for tracking the position and the heading of a vehicle using dead reckoning and a tracking device for carrying out the method

Номер: US20120116712A1
Автор: Christine Hollenstein
Принадлежит: U Blox AG

Position ( x ref ) and heading (H) of a vehicle are tracked using wheel tick numbers coming from wheel tick units ( 5 a, 5 b ) at the front wheels ( 3 a; 3 b ) only from which a velocity (v) and a heading rate (h) are calculated. The calculations are based on an intermediate wheel angle (δ). An exact solution δ ex for the same depends on the velocities of the left front wheel v l and of the right front wheel v r according to δ ex = arctan ( 2  p a 1 + p 2 + ( 1 - p 2 ) 2 - ( 2  p a ) 2 )   where   p = v l - v r v l + v r . An approximate solution δ app is calculated according to the simpler formula δ app = 1 2  arcsin   2  p a and used wherever its deviation from the exact solution δ ex is not significant, i.e., where the latter is not larger than a threshold wheel angle δ thr . Only for δ app >δ thr where the deviation is larger than, e.g., 2° or, preferably, 1°, the wheel angle according to the exact solution δ ex is used. The latter is determined in that the approximate solution δ app is first established and the corresponding exact solution δ ex read from a look-up table, interpolation being used if necessary.

Described is a motivational fitness process using motion sensing apparatus to correlate exercise performance with entertainment audio volume for the purpose of rewarding exercise performance goals and penalizing poor exercise performance. The user must exercise in a chosen target training range to maintain a desired entertainment audio volume. Motion sensors in a mobile or stationary device or worn by user provide continuous movement data to a processor unit. The processor receives and compares the user's movement data to a user-specified target range and periodically sends control commands (or not) to raise or lower audio volume output of an entertainment device. If the user's exercise pace drops below a targeted performance range, audio volume output of their entertainment device gradually decreases unless the user reacquires their performance target range at which time volume is restored. Desired volume is maintained so long as target zone performance is maintained. 1.
