DEVICE FOR DETERMINING A SPEED COMPRISING AN ACCELERATION SENSOR

摘要

The invention relates to a device for determining a speed comprising an acceleration sensor (10) provided with an acceleration signal (100) and a processing unit (20) by means of which a speed signal (110) can be determined from the acceleration signal (100). The invention is characterised in that the processing unit (20) comprises a first integrator (210) for determining a speed from the acceleration sensor (100), a second integrator (220) for determining a signal deviation of the acceleration signal (100) and an adder for subtracting the signal deviation.
