Are sequentially updated to be stored in the corresponding traveling time register 30f, traveling distance register 30e, and traveling speed register 30g in the RAM 30 (steps S2 → S3, S4).

Then, the running state data of the bicycle 1 stored in the running time register 30f, the running distance register 30e, and the running speed register 30g in the RAM 30 are sequentially read by the CPU 25, and as shown in FIG. For the liquid crystal display unit 11 of the receiver 7, for example, the running time (time 0:30) along with the current time (15:30),
It is displayed as a traveling distance (30 km) and a traveling speed (25 km / h) (step S5).

The calculation display process of each running state accompanying the running of the bicycle 1 is repeatedly executed during a certain period of time (for example, 1 min) (steps S2 to S6). on the other hand,
Even when the fixed time has not elapsed, when the front wheel rotation detection signal is not received, the depression pressure (peak values p1, p2, ...) With respect to the pedal 5b is C via the receiving circuit 27.

Based on the stored traveling distance and traveling time of the bicycle 1, the amount of exercise W of the driver up to the present is calculated according to the above equation (1) and stored in the amount of exercise register 30j (step S13).

Then, the respective exercise state data of the driver stored in the exercise load register 30k and the exercise amount register 30j in the RAM 30 are read by the CPU 25, and as shown in FIG. 8, the liquid crystal display section of the receiver 7 is displayed. 11. For example, exercise load (P8.5), exercise amount (W4.0)

FIG. 9 is a diagram showing changes over time in the pedal depression pressure updated and stored in the pedal pressure register 30l as the bicycle 1 travels in the traveling state detecting device.
That is, in the process of increasing the pedal depression pressure indicated by arrow A, for example, the upward gradient in the traveling route gradually increases, so that the depression pressure of the pedal 5b by the driver also gradually increases. In the process of lowering the pedal depression pressure indicated by, for example, the above-described upward gradient is gradually reduced, so that the depression pressure of the pedal 5b by the driver is also gradually reduced.

Accordingly, such a change over time of the pedal depression pressure is displayed as a bar graph (X) on the liquid crystal display section 11 of the receiver 7, so that the change state of the operating load on the travel route up to the present is driven. The person will be notified in detail.

Therefore, according to the traveling state detecting device having the above-mentioned configuration, the front wheel rotation detection signal (a) received from the transmitter 6 by the receiving circuit 27 and the front wheel size and the timekeeping previously stored in the tire size register 30c of the RAM 30 are stored. Circuit 2
The traveling distance, traveling time, and traveling speed of the bicycle 1 are calculated by the CPU 25 based on the time measurement data obtained by 8, and stored in the traveling distance register 30e, the traveling time register 30f, and the traveling speed register 30g in the RAM 30, and the liquid crystal display section is displayed. The pedal 5b displayed on the display 11 and detected and received by the pressure sensor 8 and the traveling distance and traveling time.
The driver's momentum W is calculated based on the stepping pressure detection signal (b) of the crank 5c, which is stored and displayed in the momentum register 30j and is stored in the crank length register 30d in the RAM 30 in advance. Of the bicycle and the exercise load P of the driver is calculated based on the crank rotation detection signal (c) detected via the reed switch 10 and stored and displayed in the exercise load register 30k. It becomes possible to know not only the running state accompanying the running but also the exercise amount W and the exercise load P of the user in real time and with a small error.

Further, as the bicycle 1 travels, the pedaling pressure value of the pedal 5b detected by the pressure sensor 8 and received by the CPU 25 via the receiving circuit 27 is sequentially updated and stored in the pedal pressure register 30l in the RAM 30. At the same time, the stepping pressure value of the pedal 5b is bar graph-displayed (X) on the liquid crystal display unit 11 of the receiver 7 in time series with the passage of time counted by the timing circuit 28. It becomes possible to know in detail the changing state of the operating load in the traveling route up to.

In the above embodiment, the pressure sensor 8 directly attached to the pedal 5b is used as a means for detecting the depression pressure of the pedal 5b. However, as shown in FIG. 10, the pressure sensor 8 is attached to the crankshaft 5e. The depression pressure of the pedal 5b may be converted and obtained based on the strain signal of the crankshaft 5e obtained by the strain gauge 31.

FIG. 10 is a view showing a state in which the strain gauge 31 is attached to the crankshaft 5e of the bicycle 1. That is, the strain signal of the crankshaft 5e output from the strain gauge 31 as the pedal 5b is depressed is the strain detection unit 3
2 and is transmitted to the receiving circuit 27 of the receiver 7 via the transmitting unit 33.

Then, the distortion detection signal of the crankshaft 5e received by the receiving circuit 27 is supplied to the CPU 25 and converted into the depression pressure on the pedal 5b.
That is, when the pressure sensor 8 in the above-described embodiment detects the depression pressure of the pedal 5b, the pedal depression of the pedal 5b can be performed to some extent without the driver actually performing the depression operation. Since the pressure is detected, a slight error occurs between the driver's actual stepping pressure and the driver's actual stepping pressure. It is possible to accurately calculate and display the amount of exercise W and the amount of exercise P of the driver.

[0060]

As described above, according to the first traveling state detecting device of the present invention, not only the traveling state of the vehicle such as the traveling distance and the traveling time of the vehicle but also the pedal directly related to the traveling operation of the vehicle, etc. Since the driver's exercise state including the operating part pressure is calculated and displayed, even if the vehicle includes a traveling route such as an uphill or a downhill where the exercise changes drastically, a large error does not occur, and the actual It is possible to calculate and display the correct exercise state.

Further, according to the second traveling state detecting device of the present invention, the operating portion pressure of the pedal or the like, which is directly related to the driver's momentum with the passage of traveling time, is sequentially time-sequentially in the bar graph format. It is possible to easily know the change over time of the operating load because it is displayed as a visual display.
