It has a reset key that is operated when resetting the calculation display processing of the running state, a display switching key that is operated when switching the display mode, etc. Various key operation signals from this key input unit 12 are supplied to the CPU 11. To be done.

The pressure setting volume 13 is for adjusting and setting the depression pressure threshold (threshold level) of the pedal 5b of the bicycle 1 to an arbitrary value. The pressure threshold setting data from the pressure setting volume 13 is
It is converted into digital data via the A / D converter 13a and given to the CPU 11. The reception circuit 14 receives the rotation detection pulse signal a of the front wheel 2 transmitted from the transmitter 6 and the depression pressure detection signal b of the pedal 5b transmitted from the transmission portion 8a of the pressure sensor 8. The rotation detection pulse signal a and the pressure detection signal b received by the circuit 14 are supplied to the CPU 11.

The crystal oscillating circuit 15 supplies a crystal oscillating signal of a predetermined cycle to the CPU 11, and the CPU 11 operates in accordance with the crystal oscillating signal. FIG. 3 is a diagram showing a register configuration of the RAM 16 included in the electronic circuit of the traveling state detecting device. The RAM 16 has a CP
The timing register 16a in which the timing data in U11 is sequentially updated and stored, the pressure threshold register 16b in which the pressure threshold data for pedal depression adjusted by the pressure setting volume 13 is stored, and the tire size setting in the key input unit 12 A tire size register 16c that stores tire size data of the front wheels 2 set by operating a key, and a running speed register that is stored by sequentially updating the running speed, running distance, and running time of the bicycle 1 calculated by the CPU 11. 16d, a traveling distance register 16e, and a traveling time register 16f are provided.

The liquid crystal display unit 17 includes the key input unit 1
2. Display of size setting data associated with the operation of the tire size setting key and pressure threshold setting associated with the operation of the pressure setting volume 13 corresponding to each display mode selected by operating the display switching key in 2. The display of data, the traveling speed data, the traveling distance data, the traveling time data, etc. stored in the RAM 16 are performed. The liquid crystal display unit 17 receives a display control signal from the CPU 11 via the display drive circuit 17a. Driven.

The CPU 11 has a program ROM (not shown) in which a running state calculation display control program is stored, and the pressure detection signal b from the receiving circuit 14 is stored therein.
When both the rotation detection pulse signal a and the rotation detection pulse signal a are supplied, the traveling speed, the traveling distance, and the traveling time of the bicycle 1 are calculated based on the rotation detection pulse signal a and the timing data and tire size data stored in the RAM 16. The various running state data calculated by the CPU 11 are stored in the corresponding registers 16d to 1 of the RAM 16 described above.
It is written in 6f and displayed on the display unit 17 as needed.

In this case, in the running state calculation display control process in the CPU 11, the pedal depression pressure detection signal b received by the receiving circuit 14 is equal to or more than the pressure threshold value preset and stored in the pressure threshold value register 16b of the RAM 16. To the receiving circuit 14 within a predetermined time.
When the rotation detection pulse signal a of the front wheel 2 is received at
Execution is started after it is determined that the vehicle has actually started running.

Next, the operation of the traveling state detecting device having the above structure will be described. FIG. 4 is a timing chart showing a reception state of the front wheel rotation detection signal (cycle pulse a) and the pedal depression pressure detection signal (pressure value b) in the receiver 7 of the traveling state detection device. FIG. 5 is a flowchart showing a traveling state detecting process by the traveling state detecting device.

That is, for example, when the bicycle 1 is pushed and walked to move the bicycle 1 to the starting point, each time the magnet 4 passes by the side of the transmitter 6 due to the rotation R of the front wheel 2, Rotation detection pulse signal a of the front wheel 2 from the transmitter 6
Is transmitted and received by the receiving circuit 14 of the receiver 7, the CPU
11 is supplied. In this case, since the user does not get on the bicycle 1, no stepping pressure is detected by the pressure sensor 8 attached to the pedal 5b, and the pressure detection supplied to the CPU 11 via the receiving circuit 14 of the receiver 7 is detected. Since the signal b does not reach the pressure threshold value set in the RAM 16 at all, the actual traveling state calculation display processing is not started (step S1).

Therefore, from the receiving circuit 14 to the CPU 11
The rotation detection pulse signal a supplied to is ignored. After that, when the bicycle 1 is moved to the traveling start point and the traveling is started by the ride of the user, the depression pressure detection signal b of the pedal 5b supplied to the CPU 11 via the receiving circuit 14 of the receiver 7 is transmitted. When the pressure threshold value set in the pressure threshold register 16b of the RAM 16 exceeds a preset pressure threshold value (step S1), a new rotation detection pulse signal a (1) from the transmitter 6 is transmitted from the transmitter 6 via the receiving circuit 14 within a predetermined time t1. When received and supplied (step S2), the CPU
In 11, it is determined that the vehicle has actually started running, and the running state calculation process of the bicycle 1 is started from the time point when the rotation detection pulse signal a (1) is received and supplied (step S).
3).

In this case, in FIG. 4, the rotation detection pulse signal a of the front wheels 2 is obtained in parallel when the depression pressure detection signal b of the pedal 5b reaches or exceeds the pressure threshold value.
Since the generation time of the rotation detection pulse signal a is before the time when the pressure threshold value of the pressure detection signal b is reached, the CPU 11
, The rotation detection pulse signal a (0) up to time t0 is ignored.

Then, the above steps S1 and S
When the running state calculation process in step S3 is started according to the determination process of No. 2, the CPU 11 causes the rotation detection pulse signal obtained within a predetermined time after the pressure detection signal b reaches a preset pressure threshold value. According to the rotation detection pulse signals a (2), (3), ...
Calculation of the running speed, running distance, and running time of the bicycle 1 is started based on the tire size data preset in the M16 tire size register 16c and the timekeeping data sequentially updated and stored in the timekeeping register 16a (step S
3) While being written in the traveling speed register 16d, the traveling distance register 16e, and the traveling time register 16f, respectively (step S4), they are displayed on the liquid crystal display unit 17 via the display drive circuit 17a (step S5).

Here, in a state where the rotation detection pulse signal a is repeatedly supplied within a predetermined time, it is judged that the traveling state by the actual riding is continued (step S).
6) Then, the traveling state calculation / display processing after step S3 is repeated in real time according to the traveling of the bicycle 1 (steps S3 to S6). After that, the traveling of the bicycle 1 is stopped, and the rotation detection pulse signal a is C for a predetermined time or more.
When it is no longer supplied to the PU 11, the series of running state calculation display processing is ended (step S6 → EN).
D).

Therefore, according to the traveling state detecting device having the above structure, the depression pressure detection signal of the pedal 5b received from the pressure sensor 8 to the receiving circuit 14 via the transmitting portion 8a is
When the pressure threshold register 16b of the RAM 16 reaches or exceeds a pressure threshold preset by the pressure setting volume 13, the transmitter 6 sends the front wheel 2 to the receiving circuit 14 as the magnet 4 attached to the front wheel 2 rotates. When the rotation detection pulse signal is received, the CPU 11 determines that the traveling of the bicycle 1 by the actual riding is started, and thereafter, the rotation detection pulse signal received by the receiving circuit 14 and the timing register 16a of the RAM 16 are received. And the traveling speed and traveling distance of the bicycle 1 based on the timekeeping data and the tire size data stored in the tire size register 16c.
The running time is calculated and sequentially updated and stored in the corresponding registers 16d to 16f of the RAM 16 and is displayed on the liquid crystal display unit 17 via the display drive circuit 17a. Even if the rotation detection pulse signal of is obtained by the CPU 11, the process of calculating the running state is not started, and the actual running state is accurate based on the rotation detection pulse signal after the actual riding, particularly, in this case, the actual running distance. Also, the actual traveling time can be calculated and displayed.

Further, the pressure threshold value, which is a criterion for judging the pedal depression due to the actual riding, is arbitrarily adjusted and set by the pressure setting volume 13, so that the degree of depression with respect to the pedal 5b at the time of starting the traveling is different for each user. The pressure threshold can be appropriately set according to the above. Further, the pressure detection signal obtained by the pressure sensor 8 attached to the pedal 5b is wirelessly transmitted via the transmitting portion 8a thereof, received by the receiving circuit 14 of the receiver 7, and then C
Since it is configured to be supplied to the PU 11, it is not necessary to provide a contact mechanism for deriving the pressure detection signal between the rotating pedal 5b and the vehicle body 5, and it is possible to easily obtain the pressure detection signal of the pedal depression. become.
