VEHICLE SHIFT CONTROL DEVICE

WIPO Patent Application WO/2013/150965

A1

The present invention provides a vehicle shift control device that is capable of preventing a vehicle from moving backward when re-accelerating after decelerating on an uphill road. If the vehicle shift control device determines, according to an uphill road deceleration determination, that the vehicle is traveling on an uphill road and is in a state of deceleration (S210), and the shift position is in a drive (D) range (S212), the motor is normal (S214), the starting gear is a first prescribed gear or lower (S216), the target starting gear is a second prescribed gear or lower (S218), the actual even number gear is a third prescribed gear or higher (S220), and the actual odd number gear is a fourth prescribed gear or higher (S222), the vehicle shift control device puts a first synchronizing mechanism, a second synchronizing mechanism and a third synchronizing mechanism in a neutral state in which none of the gears are engaged. Subsequently, the first synchronizing mechanism, the second synchronizing mechanism and the third synchronizing mechanism are activated, shifting to a gear that is appropriate for re-acceleration (S224-226).
