A control device for hybrid vehicle includes an electronic control unit. The electronic control unit is configured to: calculate required electric power required for a motor for electric power generation as electric power supplied to a motor for drive based on required drive power of the hybrid vehicle; calculate an electric power suppliable time of the capacitor; and determine a rotation speed increase standby time of the internal combustion engine such that rotation speed increase standby time becomes shorter than a spare time. The spare time is a time obtained by subtracting an electric power generation delay time from the electric power suppliable time. The electric power generation delay time is a time from a time of starting the rotation speed increase until a time of starting electric power generation of the motor for electric power generation.

Control device for hybrid vehicle

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 of the first and second differential mechanisms which are selectively connected to each other through the clutch is selectively fixed to a stationary member through a brake. The drive control device comprises: an electric motor operation control portion configured to control the second electric motor for starting the engine with an output torque of the second electric motor, when a reaction force is exerted on the first and second electric motors.

Switching conditions are defined by a threshold &#x3b1;for switching from 'power OFF control' to 'power ON control', and a threshold &#x3b1;for switching from the &#x201c;power ON control&#x201d; to the &#x201c;power OFF control&#x201d;. During a period of a shift operation, the thresholds are changed toward thresholds &#x3b2;and &#x3b2;smaller than &#x3b1;and &#x3b1;depending on a shift progress degree PRG, respectively.

A control apparatus for a hybrid vehicle power transmitting system wherein an electric motor is connected through a step-variable transmission to a drive-wheel-side output shaft to which a drive force of a main drive power source is distributed by a power distributing device, which control apparatus is configured to reduce a shifting shock upon a shifting action of the step-variable transmission wherein when

Control apparatus for vehicular power transmitting system

For raising an MG2 rotational speed MRNto a target rotational speed (low-gear rotational speed NLG), an output torque of an MG2 starts to increase at a time t. During an inertia phase (period &#x3b1;), the output torque of the MG2 is limited not to exceed a first limit value TLIMdetermined according to a shift progress degree PRG and a second limit value TLIMdetermined according to a rotational speed margin NEmgn. Since the output torque of the MG2 is sufficiently small in a final stage of the inertia phase (period &#x3b1;), output variations occurring at a time twhen torque down is performed on the MG2 can be small. The torque down of the MG1 and MG2 does not raise engine rotational speed NE.

A control method for a hybrid vehicle which includes an engine, a first motor/generator, a second motor/generator, and a manual changing device that changes a driven state of an output member of the engine that depends on a driving state of the engine and a driving state of the second motor/generator, includes the steps of detecting required driving force of the vehicle; detecting required output torque of the second motor/generator based on the required driving force when a change in a rotational speed of the engine is detected; comparing the detected required torque to the maximum permissible torque of the second motor/generator, and increasing a gear ratio when it is determined that the required output torque is greater than the maximum permissible torque.
