Abstract

PURPOSE:To adjust the drive force of a motor to a value within a constantly proper range by a method wherein the output of an electric motor is adjusted according to the increase and the decrease of a man-power drive force and correction is effected such that when a calculating running speed does not coincide with an actual running speed, the output of the electric motor is decreased. CONSTITUTION:A pedaling force F detected by a potentiometer 46, a car speed S detected from a rear wheel 14 by a car speed sensor 56, and the rotation speed (s) of a crank shaft 32 detected by a speed sensor 58 are inputted to a controller 54. A car speed S is compared with a crank shaft rotation speed (s) by a signal comparing part 60 and the speed (p) of a speed change mechanism 40 is detected. Based on data of a memory 64, the auxiliary force of a motor 22 to the pedaling force F, namely, a motor drive force is computed by a change gear ratio and auxiliary computer 62 and a control signal (q) responding to the computed result is outputted. When a change gear ratio determined by the controller 54 is brought into no coincidence with a set change gear ratio, it is decided by the controller 54 that abnormality occurs to the car speed sensor 56 and control is effected so that a motor output is decreased.

2. Description of the Related Art It is known that the pedaling force is detected and the driving force of an electric motor is controlled in accordance with the magnitude of the pedaling force (Japanese Unexamined Patent Publication No. S50-125438 and Japanese Utility Model Laid-Open No. 56-76590).
No. 2-74491, etc.). That is, when the burden of human power is large, the driving force of the electric motor is also increased to reduce the load of human power.

However, when the vehicle speed is calculated by using the rotational speed of the crankshaft and the gear ratio that are linked to the pedaling of the driver, the calculated vehicle speed is the actual vehicle speed (actual vehicle speed).
Can be inconsistent with. When the gear ratio is calculated by detecting the actual vehicle speed and the crankshaft rotation speed, the calculated gear ratio may be different from the initially set gear ratio. For example, when there is a malfunction of a sensor such as a speed sensor. In such a case, the motor output may become excessively large, so that appropriate motor output control corresponding to the vehicle speed cannot be performed.

It is also conceivable that the vehicle speed is detected from the rotation speed of the rotation transmission mechanism portion (for example, wheels) corresponding to the actual vehicle speed. However, in this case, the rotation speed sensor is arranged at a position exposed to the outside, such as near the axle of the wheel, or at a position relatively easy to touch. For this reason, there is a problem that damage is caused by contact with an obstacle or the speed is easily deceived by unauthorized modification.

In the embodiment of FIG. 3, the gear shift characteristic in a normal state where the gear shift operation detecting sensor 68 is not modified is as shown in FIG. In FIG. 4, the horizontal axis t indicates the elapsed time after starting. In this normal case, the shift detection signal which is the output of the shift operation detecting sensor 68 for detecting the shift stage p of the shift mechanism 40 matches the actual shift stages p 1 , p 2 and p 3 .

In FIG. 5, the shift operation detecting sensor 68 is arranged at a high speed p.
The following shows the shift characteristics when the modification to fix to 3 is performed. In this case, the detected shift stage p is always the high speed stage p 3 , and therefore the calculated vehicle speed S C using this shifts stepwise each time an actual shift is performed. Therefore, since the calculated vehicle speed S R changes stepwise at the time of gear shifting, it is determined that the remodeling has been performed, and the gear ratio determining / signal correcting unit 70 fixes the gear p to the low gear p 1 as described above. Then, the driving force T M of the motor 22 is reduced.
