摘要： A hybrid vehicle including an engine having a catalyst in an exhaust passage, first and second motor generators, a battery and a power transmission mechanism coupling a drive shaft, the engine and the motor generators by a gear mechanism such that torque is transmittable, and its control method, are provided. When a coolant temperature is a threshold or below, catalyst warm-up operation for starting the engine and retarding an ignition timing by a retardation amount is executed. When a battery level is a threshold or below, forced charging operation for starting the engine and charging the battery by driving the first motor generator is executed. During the forced charging operation, an engine load is changed on the basis of the battery level. When the catalyst warm-up operation is executed during the forced charging operation, the retardation amount for facilitating warm-up of the catalyst is reduced as the engine load increases.

摘要： A drive control device for a hybrid vehicle is provided with a differential device including four rotary elements; and an engine, first and second electric motors and an output rotary member which are respectively connected to the four rotary elements. One of the four rotary elements is constituted by a rotary component of a first differential mechanism and a rotary component of a second differential mechanism selectively connected through a clutch, and one of the rotary components is selectively fixed to a stationary member through a brake. The hybrid vehicle is selectively placed in a plurality of drive modes according to respective combinations of engaged and released states of the clutch and the brake. The drive control device comprises: a resonance point change control portion configured to switch the clutch from a presently selected one of the engaged and released states to the other, irrespective of a presently established one of the drive modes of the hybrid vehicle, when the engine is operated in a loaded condition while a torque of the second electric motor falls within a predetermined narrow range including zero. The first differential mechanism is provided with a first rotary element connected to the first electric motor, a second rotary element connected to the engine, and a third rotary element connected to the output rotary member, while the second differential mechanism is provided with a first rotary element connected to the second electric motor, a second rotary element, and a third rotary element, one of the second and third rotary elements of the second differential mechanism being connected to the third rotary element of the first differential mechanism, and the clutch is configured to selectively connect the second rotary element of the first differential mechanism, and the other of the second and third rotary elements of the second differential mechanism which is not connected to the third rotary element of the first differential mechanism, to each other, while the brake is configured to selectively fix the other of the second and third rotary elements of the second differential mechanism which is not connected to the third rotary element of the first differential mechanism, to the stationary member.
