PROBLEM TO BE SOLVED: To prevent the occurrence of a gear shift shock during conversion of a range to effect forward running during reversing by effecting slip control of a clutch on the forward coupling side when conversion of an R→D range is effected for forward running during reversing. SOLUTION: After an R→D conversion signal is applied during reversing of a vehicle, under a condition that an engine is in an idle state, an initial duty control signal, a soft apply duty control signal, a feedback duty signal, and an open loop duty control signal at a given rise inclination after correction of a duty are outputted, in the order, and confirmed. After it is decided that gear shifting synchronism is completed, a throttle valve opening amount is corrected. By completing duty control after a duty value is raised to an arbitrary reference value and maintained during an arbitrary time, a gear shift shock occurring during conversion of a range for forward running during reversing is prevented from occurring. |
