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.

A drive control apparatus for a vehicle includes an engine, an electric motor, a clutch mechanism, an engine rotation sensor, a motor rotation sensor, an acceleration and deceleration intention detecting portion, and a controller. The controller controls a rotation speed of the engine to be an acceleration intention target value greater than a rotation speed of the motor and thereafter brings the clutch mechanism into the engagement state in a case where the acceleration and deceleration intention detecting portion detects that the vehicle is in an acceleration intention mode, and controls the rotation speed of the engine to be a deceleration intention target value smaller than the rotation speed of the motor and thereafter brings the clutch mechanism into the engagement state in a case where the acceleration and deceleration intention detecting portion detects that the vehicle is in a deceleration intention mode.

Drive control apparatus for vehicle and method of controlling drive apparatus for 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.

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.

Control device for vehicle

The control procedure of the invention sets a target rotation speed Ne* and a target torque Te* of an engine corresponding to a torque demand Td* required for driving the vehicle (steps Sto S). In response to an upshift request for a gear of a transmission, the control procedure sets a positive pre-upshift target rotation speed Nmtag to a target rotation speed Nm* of a first motor (step S). The control procedure changes the target rotation speed Ne* of the engine to a specific rotation speed corresponding to the pre-upshift target rotation speed Nmtag of the first motor (step S) and subsequently implements an actual change of the gear in the transmission (step S). This arrangement effectively restrains a battery from being overcharged with excess electric power.

Shift control system for hybrid vehicles

A switched reluctance motor is provided with multi-phase coils on the stator poles. An energization on angle, a first energization off angle, a second energization off angle and a target value corresponding to an angle of rotation are determined with respect to each coil on the basis of a target torque and a rotation speed. A pair of transistors which act as switching elements are both turned on when the angle of rotation is reached at the energization on angle. One transistor is turned off if a value of an actual current is target value of the current while the angle of rotation is not reached at the first energization off angle. The same transistor is turned off irrespective of the magnitude of the value of the actual current and the target value of the current when the angle of rotation is reached at the first energization off angle. The transistors are both turned off when the angle of rotation is reached at the second energization off angle.
