<p><P>PROBLEM TO BE SOLVED: To provide user-friendly electronic equipment that notifies a driver, etc., of an interchange exit for discount in an early stage, drawing the attention of the driver to the interchange exit for discount, and allowing the driver to receive a discount more reliably than before. <P>SOLUTION: Control is made to output an approach alarm is issued when approaching the farthest interchange exit that satisfies a discount condition (S160: Y) during the time between when entry to an interchange entrance is detected (S110: Y)and when exit from a toll road to a general road is detected (S150: Y). After the exit from the toll road to the general road is detected (S150: Y), since information stored in a nonvolatile memory of a control part 18 in S130 is cleared (S180), no approach alarm is issued even if a vehicle approaches an interchange exit from the general road side. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
