Motor vehicle speed computing method, involves computing acceleration based on speed that is computed at time point of change of final distance pulse and speed that lies within time base before change of distance pulse

摘要

#CMT# #/CMT# The method involves computing a distance covered by a wheel if a final computation of value of a displacement sensor counter has changed within a time basis. An actual speed is determined from the distance and is stored as a basic value. Another actual speed is computed by an extrapolation based on acceleration, if no distance pulse of the counter takes place within the time basis. The acceleration is computed based on a speed computed at the time point of change of a final distance pulse and a speed lying within the time base before the change of the distance pulse. #CMT# : #/CMT# An independent claim is also included for a computer program product stored on a computer-application medium with computer readable program units for executing a method for computing a speed of a vehicle during slow approach. #CMT#USE : #/CMT# Method for computing a speed of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The method reliably computes the speed of the motor vehicle even at slow-speeds of even less than 1 kilometer per an hour. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flow chart representing a method for computing a speed of a vehicle during slow approach.
