Abstract
A power transmitting system for a motor vehicle having a manually operated member for selecting one of operating states of the power transmitting system, which include a neutral state, wherein a power transmitting path between a drive power source and a drive wheel of the motor vehicle is electrically disconnected by a first power disconnecting device, and is mechanically disconnected by a second power disconnecting device which is operated in response to an operation the manually operated member to the neutral state. Also disclosed is a hybrid drive system including a start-up control device operated upon operation of the manually operated member from a non-drive state to a drive state, for controlling the reaction torque of a motor/generator to rise according to one of predetermined rise characteristics which is selected depending upon a vehicle running condition.
