TRANSMISSION APPARATUS

摘要

A transmission apparatus mounted on a vehicle has a front-wheel speed sensor for sensing a rotation speed of a front wheel. A control unit has a ratio-change correction part that determines a correction in transmission control of the transmission apparatus using the rotation speed of the front wheel sensed by a front-wheel speed sensor. The control unit limits execution of the correction under a condition that an external device is connected to a connector. Thereby, the execution of the correction based on the rotation speed of the front wheel without a worker's intention during driving on a chassis dynamo may be suppressed.

1. A transmission apparatus, comprising:
an actuator that changes a transmission ratio of a transmission; a front-wheel speed sensor that detects and outputs a rotation speed of a front wheel; a transmission ratio sensor that detects and outputs a value of the transmission ratio; and a control unit that receives the value of the transmission ratio from the transmission ratio sensor and receives the rotation speed from the front-wheel speed sensor, the control unit setting and controlling the transmission ratio by driving the actuator, the control unit including
a ratio-change correction part that determines a correction in the controlling of the transmission ratio by the control unit based upon the rotation speed, anda connector for connecting to an external device to enable communication between the control unit and the external device, the control unit limiting an execution of the correction under a condition that the external device being connected to the connector.
