PROBLEM TO BE SOLVED: To provide an axle rotation detection pulse counter capable of accurately counting pulses of pulse signals to be output from an axle rotation detection part, and a tire position determination system.SOLUTION: Pulse signals Spl are input in an axle rotation detection pulse counter 23 from axle rotation detection parts 22a-22d provided in respective axles 18a-18d, and these pulse count values are counted. The axle rotation detection pulse counter 23 acquires travel information Ddr through CAN, etc., and counts the pulse count values on the basis of the acquired travel information Ddr when the pulse count values of the respective axles 18a-18d are counted. Specifically, the pulse count values are counted by adding count values when a vehicle 1 travels forward, and subtracting the count values when the vehicle 1 travels backward. |
