Automatic change-gear control device for use in electromobile |
摘要 |
An automatic change-gear control device for use in an electromobile which incorporates a multi-stage change gear drive system. This automatic change gear control device selects and controls a gear ratio for an optimum ratio, depending on the running condition of a vehicle, and particularly provides a change-gear logic by detecting a load torque for every individual condition, in an attempt to improve the running performance of a vehicle at the time of acceleration or at the time of running on an upward slope.
