OSTI ID:5247547

A method is described of electronically controlling a vehicle having a clutch controlled by a clutch actuator, a transmission for changing gear ratios by a transmission actuator and having a synchromesh mechanism provided at gear positions other than a reverse gear position, and an electronic control unit for controlling both actuators in accordance with the vehicle running conditions. The method consists of: (a) disengaging the clutch in response to a command delivered to the clutch actuator by the electronic control unit at the same time that the transmission starts to be switched to the reverse gear position; (b) switching the transmission to a neutral gear position in response to a command delivered to the transmission actuator by the electronic control unit after the clutch is disengaged; (c) switching the transmission to a gear position provided with the synchromesh mechanism in response to a command delivered to the transmission actuator by the electronic control unit with the clutch remaining in the disengaged state; and (d) switching the transmission to the reverse gear position in response to a command delivered to the transmission actuator by the electronic control unit with the clutch remaining in the disengaged state.
