Abstract: A hybrid vehicle includes an internal combustion engine and a rotary electric machine. The internal combustion engine includes a variable valve actuating device configured to change an operation characteristic of an intake valve. The rotary electric machine is configured to generate driving force for propelling the hybrid vehicle. A controller for the hybrid vehicle includes a traveling control unit and a valve actuation control unit. The traveling control unit executes traveling control for causing the hybrid vehicle to travel by using the driving force of the rotary electric machine while stopping the internal combustion engine. The traveling control unit starts up the internal combustion engine while executing the traveling control. The valve actuation control unit controls the variable valve actuating device. The valve actuation control unit, when the internal combustion engine is started up while the traveling control is executed, sets at least one of a valve lift and valve operating angle of the intake valve such that the at least one of the valve lift and valve operating angle of the intake valve when the hybrid vehicle travels at a first vehicle speed is smaller than the corresponding at least one of the valve lift and valve operating angle of the intake valve when the hybrid vehicle travels at a second vehicle speed. The second vehicle speed is lower than the first vehicle speed.

Abstract: An engine valve driving device includes a rocker arm attached at one end to a valve stem and carrying at its opposite end a roller which engages the surfaces of a stepped cam plate. The cam plate has a horizontal surface which includes upper and lower portions joined by an inclined portion so that horizontal reciprocating motion operates the rocker arm and the connected valve. The cam plate is connected to a rotary cam crank shaft so that rotation of the crank shaft produces linear reciprocating motion in the cam plate. The connection between the cam shaft and the cam plate is adjustable, as by a hydraulic cylinder, to vary the gap between the cam plate and the cam shaft and to thereby vary the timing of the motion of the valve with respect to the rotation of the cam shaft. In an alternative form, the connection between the cam and the cam shaft may be a pivotal lever, with the pivot point of the lever being movable to provide timing adjustment.
