使用されている。The most common drive system for two-wheeled vehicles with a motor is the rear-wheel drive system. A chain transmission type is often used as a transmission device for power from the prime mover to the rear wheels, and a gear change or continuously variable belt type is often used as a transmission means. A gasoline engine is mainly used as the prime mover.

転数が独立に制御される。A two-wheeled vehicle that uses an electric motor as a drive source was developed in 1982-1.
It is described in Publication No. 4903. This has an outer rotor type motor installed in each of the front and rear wheels, and the rotation speed of each wheel is controlled independently to eliminate tire slip.
前者の後輪駆動方式の場合、後輪側の重量が重く、前後
のバランスが悪い。In the case of the former rear-wheel drive system, the weight on the rear wheel side is heavy and the front-rear balance is poor.

やや安定性にかくといわれている。In addition, the rear wheel drive type can be used on roads in cross country or rainy days,
It is said that driving on rough terrain, such as sandy or snowy roads, is somewhat less stable than front-wheel drive.

操作に問題を残す。It has long been known that front-wheel drive systems are advantageous when riding on rough terrain, but as mentioned above, conventional motorcycles were mainly rear-wheel drive systems using a steering wheel. It is very difficult to drive with a chen, it is not practical, and there are many problems6. If an electric motor is used as the drive source as in the latter case, it is possible to house it in the front wheel and make it front-wheel drive. It is possible. However, the two-wheeled vehicle described in Japanese Utility Model Application Publication No. 6244903 uses a system in which both wheels are driven independently, and the motor used for this is a salient pole type motor, which has a very strong cogging torque and low speed. It has poor controllability, making it difficult to operate the vehicle especially when parking or parking the vehicle, leaving problems with operation during slight movements.
本発明は上述の問題点を解決するためになされたもので

It is something to do.

御信号の位相を調節することが好適である。The two-wheeled vehicle further includes a current detection means for detecting a current flowing through one of the phases of the armature, and the control means controls the phase of the current detected by the current detection means and the rotational position detection means. It is preferable to adjust the phase of the control signal based on the rotational position detected by the control signal so that the induced electromotive force and the current in this phase are in phase.

It is preferable to output a signal.
二輪車の駆動源としてブラシレス直流モータを採用する

る。By adopting a brushless DC motor as the drive source of a motorcycle, it becomes possible to drive the motorcycle with the front wheels, which improves stability when riding on rough terrain, and improves the weight balance between the front and rear wheels, making it suitable for general driving. Stability is also improved.

大電流を流す必要があり、そのために磁界分布が乱れる
。したがって、磁気式センサの代わりに光学式センサを
使用することが好ましい。Normally, a magnetic sensor such as a Hall element is used to detect the rotational position of the rotor of a brushless DC motor, but in the case of a motor that drives a two-wheeled vehicle, a relatively large current must be passed through the armature. Therefore, the magnetic field distribution is disturbed. Therefore, it is preferable to use optical sensors instead of magnetic sensors.

いる。Further, brushless motors are usually small-sized ones used in AV equipment and the like, and the inductance value relative to the direct current resistance of the windings is usually small. Therefore, little consideration is given to efficiency, and it is common to apply a voltage to each winding in synchronization with the rotational position of the rotor. However, since the brushless DC motor used in the present invention requires a large output, the inductance value relative to the DC resistance is large, and the presence of reactive power cannot be ignored. Therefore, as described above, efficiency≠1 can be achieved by detecting the phase of the current flowing through the windings and adjusting the timing of voltage application so that this and the induced electromotive force are in phase. In addition, by adopting such a control method,
Excellent under-axis characteristics, i.e. characteristics in which the rotational speed does not significantly decrease as torque increases, are obtained, resulting in a motor with good speed controllability and smooth speed control from low to high speed ranges. . Note that such a control system for a brushless DC motor and its effects are disclosed in detail in Japanese Patent Laid-Open No. 1-248987 and Japanese Patent Application No. 1-120014 filed by the applicant of the present invention.
