A drive apparatus for a hybrid vehicle includes: (a) a hybrid drive unit having (a-1) an automatic transmission, (a-2) a first rotating machine and (a-3) an engine connected to the first rotating machine through a hydraulically-operated connecting/disconnecting device; (b) an electric drive unit including a second rotating machine; and (c) a hybrid control device configured, in event of an anomaly that disables a shift control of the automatic transmission, to generate an electric power by causing the first rotating machine to be rotated by the engine and drive the hybrid vehicle to run by causing the second rotating machine of the electric drive unit to be operated with use of the generated electric power, in a state in which a power transmission through the automatic transmission is cut off and the connecting/disconnecting device is engaged.

Drive apparatus for hybrid vehicle

A drive-force control apparatus for a vehicle including a first drive apparatus for driving a first pair of wheels and a second drive apparatus for driving a second pair of wheels. Each of the first pair of wheels is one of front and rear wheels of the vehicle, and each of the second pair of wheels is the other of the front and rear wheels. During running of the vehicle on a wave-like road, the control apparatus reduces a drive-force share ratio of one of the first and second drive apparatuses, and to increases a drive-force share ratio of the other of the first and second drive apparatuses, wherein the one of the first and second drive apparatuses includes a weakest part that is to be damaged the most easily among parts composing the first and second drive apparatuses, by resonance caused by the running on the wave-like road.

Drive-force control apparatus for vehicle

A clutch connecting/disconnecting device comprises: a clutch pedal; a clutch cylinder; a depression force transmission mechanism; and an actuator. The depression force transmission mechanism is configured to include a cylinder device. The cylinder device includes an input piston, an output piston, a first oil chamber, and a second oil chamber. A pressure receiving area on the first oil chamber side of the output piston is made equal to a pressure receiving area on the second oil chamber side of the output piston. The first oil chamber and the second oil chamber are connected via an electromagnetic valve connecting and disconnecting between the first oil chamber and the second oil chamber, and the actuator is connected to the output piston in a power transmitting manner.
