A vehicle having a method of determining the change in direction when the vehicle navigation apparatus and such a device for performing such a method

摘要

(57) Abstract The manner which decides the direction change of the vehicle, the dead reckoning which uses the sensor which is provided on two wheels is run. In order to compensate the difference between both wheels, aforementioned manner uses specified parameter the occasion where the data from the aforementioned wheel sensor treats. This invention runs aforementioned manner by evaluating aforementioned parameter the normal operational time of the particular vehicle. These parameters adaptation to the change status where the particular vehicle encounters to reason. Evaluation is run by comparing with the direction data which is decided separately with the data from the specified period aforementioned wheel sensor.
