Abstract
One-way clutches OWC1 and OWC2 are provided on output sides of transmissions TM1 and TM2, and the transmissions TM1 and TM2 mechanically lock when the output member 121 of the one-way clutches OWC1 and OWC2 is reversely rotated to the backward side. Clutch mechanisms CL1 and CL2 are interposed between the output member 121 and a driving target member 11 connected to a driving wheel 2. According to uphill start conditions, a controller 5 makes any one of the clutch mechanisms CL1 and CL2 enter ON state when a vehicle-backward-movement prevention control is determined to be required and the controller 5 makes the clutch mechanisms CL1 and CL2 enter OFF state when the vehicle-backward-movement prevention control is determined to be not required. Thus, it is possible to provide a vehicle driving system capable of performing a hill hold assist function with a simple control.
