ABSTRACT:
A method for computing a current vehicle speed value from a detected vehicle speed value derived from a pulse signal, said method provided data which can be used in a control process such as a cruise control of a vehicle, in which the current vehicle speed value is predicted from a previously computed vehicle speed value after an abnormal state of the current detected vehicle speed value is detected; and a cancel signal is produced for aborting the control process when the abnormal state has persisted for more than a certain time period. Thus, the derivation of an abnormal computed vehicle speed value is prevented when a temporary abnormal condition of the detected vehicle speed value has occurred, and a cancel signal, which may be used for aborting the operation of the control process, is produced when the abnormal condition of the detected vehicle speed has persisted for more than a certain time period, whereby the control system can respond to the abnormal conditions of the detected vehicle speed value in optimal fashion, and convenience and safety are both maximized.
