Abstract

A vehicle transmission control apparatus includes an expected-acceleration calculator configured to calculate an expected acceleration of a vehicle based on at least an engine load and a vehicle speed. An actual-acceleration calculator is configured to calculate an actual acceleration of the vehicle. An uphill determination device is configured to calculate an uphill determination value based on a difference between the expected acceleration and the actual acceleration and configured to calculate a corrected uphill determination value by subjecting the uphill determination value to moderating calculation using a moderating coefficient and to update the corrected uphill determination value in accordance with the moderating coefficient. A transmission-characteristic selecting device is configured to select one of transmission characteristics based on the corrected uphill determination value. A transmission controller is configured to perform transmission control based on the transmission characteristic selected by the transmission-characteristic selecting device.
