Abstract
A transmission control apparatus is provided for a straddle-type vehicle that has a clutch and a transmission with a dog clutch having a first gear and a second gear. The transmission control apparatus includes a clutch actuator configured to engage and disengage the clutch. A transmission actuator is configured to change a gear of the transmission. An input device is configured to generate a gear change command. A first sensor is configured to determine whether the vehicle is in a standstill condition. A controller is operatively connected to the clutch actuator, the transmission actuator and the first sensor. The controller is configured to, in response to the gear change command, set the clutch position between a partially engaged position and a completely released position if the vehicle is standing still as determined by the first sensor.
