A control device for a hybrid vehicle includes a portion determining whether an engine torque is necessary, a portion controlling a motor to make a motor torque be a target torque, an engine rotation speed control portion controlling an engine output shaft to rotate at a target engine rotation speed for sudden start/reacceleration while the clutch being disengaged after starting the engine and before an actual rotation speed of the engine output shaft exceeds a reference target engine rotation speed in a case where the engine torque is necessary, a control portion engaging the clutch after the actual rotation speed exceeds the reference target engine rotation speed, and a portion controlling the engine so that the engine torque is assumed to be a target torque by canceling the control by the engine rotation speed control portion after the actual rotation speed exceeds the reference target engine rotation speed.

Control device for hybrid vehicle

In a transmission control device for a hybrid vehicle, when an engine torque is equal to or less than a predetermined value during a constant speed traveling, a learning engine rotational speed is set to a rotational speed being higher by +&#x3b1; than the present engine rotational speed. Then, a learning engine torque is calculated that corresponds to the learning engine rotational speed, a learning clutch actuator operation amount is obtained that corresponds to the learning clutch torque, and a clutch actuator is operated based on the learning clutch actuator operation amount. Thereafter, when the engine rotational speed and the engine torque are in stable states, a clutch torque value corresponding to the learning clutch actuator operation amount is compensated by a stable engine torque value.

Transmission control device for hybrid vehicle

The gear shifting control device comprises a speed change operation completion detecting portion, a rotation difference judging portion for judging whether or not the absolute difference between the engine rotation speed and the input rotation speed exceeds a predetermined value and a clutch torque&#x2014;operating amount correcting portion which replaces the clutch torque corresponding to the clutch actuator operating amount corresponding to the target clutch torque with a presumed clutch torque. Thus the correction accuracy for the clutch actuator operating amount can be improved by learning a speed change state by extracting a suitable state for learning.

Gear shifting control device for hybrid vehicle

The clutch control device for a hybrid vehicle comprises an engine, an automated manual transmission, a clutch device and a clutch actuator concluding an output rod and a master cylinder which generates a hydraulic pressure therein by closing an idle port in response to the stroke of the output rod, a slave cylinder in fluid communication with the master cylinder through a passage and controlling the clutch device to be in engagement state or disengagement state operated by the hydraulic pressure generated by the master cylinder and a clutch engagement state holding control portion for temporarily holding the clutch device to be in the engagement state by operating the master cylinder to close the idle port after the engagement state under the vehicle being running under a motor drive mode continued for a predetermined time.

Hybrid vehicle clutch control device

A control apparatus of a hybrid vehicle includes an automatic transmission, a clutch, a motor, a battery, a driving assist control device performing a driving assist control by driving the motor to generate an assist torque, a gear shift assist control device performing a gear shift assist control by driving the motor in response to a decrease of the engine torque caused by the disengagement state of the clutch, an SOC value detection device detecting an SOC value, and a first mode switch device switching an operation mode of the hybrid vehicle from a normal mode in which the driving assist control and the gear shift assist control are performed to a battery power preserving mode in which the driving assist control is prohibited and the gear shift assist control is permitted in a case where the SOC value is equal to or smaller than a first predetermined value.

Control apparatus of hybrid vehicle

A gear shift control device for controlling a hybrid vehicle drive system including an engine, an automated transmission, a clutch, and a motor generator, includes a torque indication device for indicating a driver request torque determined in accordance with an operation amount of an accelerator operated by a driver, a power generation interruption device changing a vehicle state to an engine driven state using all of the engine torque when a preliminary gear shift condition is satisfied in a state where the engine drives a driving wheel and the motor generator is actuated to generate an electric power, and a gear shift control device reducing the engine torque and generating an assist torque by actuating the motor generator, disconnecting the clutch, and returning the clutch to a connected state after changing gear sets of the gear train when a gear shift condition of the automated transmission is satisfied.
