DETAILED DESCRIPTION OF THE INVENTION
A controller having a dry battery of the present invention will be described with reference to FIG. 1 showing an embodiment thereof. 1 differs from the conventional FIG. 3 in that switching elements 6 and 8 are provided in series with the shift setting device 3 and the display device 5 of FIG. That is, 1 is a dry battery, 2 is a control device for instructing a speed change motor during a speed change, and commands for displaying speed, distance, time, etc., 3 is a speed change setting device for instructing a set value at the time of speed change, and 4 is a control. A shift motor that receives a shift command signal from the device 2 and that is driven at the time of shifting, 5 is a display device that receives a display command signal from the control device 2 and displays speed, travel distance, time, and the like, and 7 and 9 are shift setters. 3 and the resistance provided at the control terminal of the switching elements 6 and 8 provided in series with the display device 5. Reference numeral 10 denotes a speed detector, and reference numerals 11 and 12 denote a manual start switch and an automatic start switch that switches automatically during manual operation.
[0010]
When the bicycle is running, the set value V2 of the shift setting device is input to the control device 2 as a function of the terminal voltage V1 of the dry battery 1. The control device 2 receives the shift setting value V2, the terminal voltage V1 of the dry battery 1, and the speed detection signal of the speed detector, performs digital processing, and outputs a shift command signal and a display command signal. Then, the shift motor 4 is shifted by the shift command signal of the control device 2, and the speed, travel distance, time, etc. are displayed on the display device 5 by the display command signal. When the bicycle is stopped for 5 minutes or more, for example, the control device 2 turns off the switching elements 6 and 8 and cuts off the current supply to the shift setting device 3 and the display device 5. Thereby, loss is suppressed and the life of the dry battery 1 is lengthened.
[0011]
Next, the example of the flowchart regarding the display of the display apparatus at the time of the said driving | running | working and a driving | running | working stop is demonstrated using FIG. First, the speed detector 10 detects the speed and determines whether the vehicle is traveling or stopped. If the vehicle is traveling, the display device 5 displays the speed, travel distance, time, and the like.
[0012]
If the traveling is stopped, it is determined whether the display device 5 is forced to display manually or automatically. If it is set to manual, the display device 5 forcibly displays the speed, travel distance, time, and the like.
[0013]
If it is set to automatically display on the display device 5, the first timer in the control device 2 is counted. If the first timer is counting, the display device 5 displays speed, distance traveled, time, and the like. For example, when the running is continuously stopped for 5 minutes and the first timer counts up, the control device 2 turns off the switching element 8, shuts off the power supply to the display device 5, the speed by the display device 5, Stops display of mileage, time, etc. When the bicycle starts running again, the speed detection signal of the speed detector 10 is input to the control device 2 and the above-described operation is repeated.
[0014]
When the manual start switch 11 is operated when the display device 2 is stopped during traveling, the second timer in the control device 2 starts counting. When the second timer is counting, the display device 5 displays speed, travel distance, time, and the like. When the count of the second timer proceeds and the time is up, the manual display on the display device 2 is switched to the automatic display.
[0015]
In the embodiment of the soft program, the power supply to the display device 5 is cut off when the vehicle is stopped. However, when the vehicle is stopped, the current supply to the display device 5 is cut off and the switching element 6 is turned off to change the speed. It is desirable to cut off the power supply to the setting device 3. Furthermore, not only the current supply to the display device 5 and the speed setter 3 may be interrupted, but other loads of the dry battery may be interrupted by providing a switching element. In the above embodiment, the current supply to the display device 5 and the gear shift setting device 3 is cut off when the running is stopped for 5 minutes. However, a time other than the 5 minutes may be set. .
[0016]
【The invention's effect】
According to the present invention, when the running is continuously stopped for a predetermined time, for example, 5 minutes, the current supplied to at least one of the display device and the shift setting device can be cut off to reduce the power consumption. Can extend the service life.
