JUDGMENT METHOD OF DRIVING SPEED OF VEHICLE

摘要

PURPOSE: A method of determining a speed of a vehicle is provided to reduce a manufacturing cost by simplifying a program. CONSTITUTION: An ECU(Electronic Control Unit) receives a signal about a speed of a vehicle from a speed sensor and integrates the signal. The integrated value is converted to an absolute value. An interval of pulses is counted by the converted value. A corresponding flag is set to 1 when the number of pulses is within a set range. The interval of pulses is continuously counted by clearing. The flag is set to 0 when the number of pulses is not within the set range.
