摘要： A control system (60) for a hybrid vehicle (1) includes a mode selection unit (200) for start request of an engine (10); a slip determination unit (410) for determining whether or not a second clutch (25) is allowed to slip; and a start determination unit (420) for determining whether or not to allow the engine (10) to start. The start determination unit (420) prevents the engine (10) from starting when an input rotation speed (Ni) or an output rotation speed (No) (= vehicle speed (VSP)) of an automatic transmission (40) is less than a predetermined value in the presence of the start request of the engine (10) from the mode selection unit (200) and the slip determination unit (410) determines that the second clutch (25) is not allowed to slip.

摘要： The purpose is to reduce an engine start shock when there is a request to start the engine in response to the accelerator pedal depression and the slip polarity of the second clutch is negative. The control device for a hybrid vehicle is provided with an engine (1), a motor/generator (2), a first clutch (4), a second clutch (5), and mechanism for engine start permission controlling operation ( FIG. 13 ). The first clutch (4) is interposed between the engine (1) and the motor/generator (2), and is selectively engaged during engine start in which the motor generator (2) is operated as the starter motor. The second clutch (5) is interposed between the motor/generator (2) and tires (7, 7), and is slip-engaged when the engine is started. The mechanism for engine start permission controlling operation ( FIG. 13 ) withholds or delays the starting of cranking of the engine (1) until the slip polarity becomes positive when the engine start request is produced in response to a drive force request associated with increase in the accelerator pedal opening and the slip polarity of the second clutch (5) is negative.

摘要： The object of the present invention is to improve the vehicle behavior response to accelerator operation when the second clutch is in slip engagement after the engine start control has begun. The hybrid vehicle control device has an engine (1), a motor/generator (2), a first clutch (4), a second clutch (5), and an engine start control means ( FIG. 11 ). The first clutch (4) is disposed between the engine (1) and the motor/generator (2). The second clutch (5) is disposed between the motor/generator (2) and tires (7, 7). The engine start control means ( FIG. 11 ) has a CL2 slip transition control section (step S512 to step S515) configured to control a transition of the second clutch (5) to slip engagement when an engine start control is begun based on a mode transition request resulting from an accelerator depression operation, by increasing the torque transmission capacity of the second clutch (5) according to a prescribed slope after dropping the torque transmission capacity of the second clutch (5) to a value smaller than a target drive force.

摘要： When the driver requests to start the vehicle with the brake OFF and depressing on the accelerator pedal APO, and thereby a target drive torque exceeds a gradient load, prior to exceeding, in order to avoid excess current being supplied to the motor, the upper limit of motor speed tNm, which is the input speed of a second clutch is set to a value less than a slip detectable limit value ÉLLIM at which it becomes possible to detect slip rotation, i.e. the difference over the output side rotation speed. When the target drive torque exceeds the gradient load, the lower limit of the input speed of the second clutch (the motor speed tNm) is set to a value equal to or greater than ÉLLIM so that the required driving force can be achieved by the gradient load corresponding driving force control.

摘要： The object of the present invention is to realize the motor electric power generation in the allowed range while suppressing the variation in the clutch input rotational speed when the input rotational speed control of the start clutch is switched from the motor rotational speed control to the engine rotational speed control. The hybrid vehicle control device has an engine 1, a motor/generator 2, a second clutch 5 as the start clutch, and a transient control mode switching means ( FIG. 11 ). Here, the second clutch 5 is arranged in the driving force transmission system from the motor/generator 2 to the wheels 7 and 7 and is engaged under the input rotational speed control. The transient control mode switching means works as follows: when the input rotational speed control of the second clutch 5 is switched from the motor rotational speed control to the engine rotational speed control, the motor rotational speed control is maintained, and both the motor rotational speed control and the engine rotational speed control are carried out at the same time until a determination is made that the engine torque is stable; after a determination is made that the engine torque is stable, the control is switched from the motor rotational speed control to the motor torque control.

摘要： When there is a requirement on switching from the electrically driven drive (EV) mode to the hybrid drive (HEV) mode by changing the accelerator position opening APO, the torque capacity tTc1 is generated for the first clutch (CL1) to start the engine. However, as tTc1 is at ²1, the engine rotational speed Ne is quickly increased to the high-speed region free of the influence of the compressive reactive force of the engine; once the engine rotational speed Ne becomes the high-speed region, the engine rotational speed is decreased as tTc1 and is at ²2. Consequently, it is possible to quickly pass through the low engine rotational speed region as the engine rotational speed torque is increased under the influence of the compressive reactive force, and avoiding the poor acceleration, as can be seen from the smooth variation of the time sequence increase of the transmission output rotational speed No as indicated by ²3, is possible.

摘要： Disclosed is a hybrid vehicle control device capable of achieving stable input torque control and torque capacity control of the clutch. When transitioning between a slip drive mode in which the vehicle travels by controlling the rotation speed of the drive source and controlling the slip state of a starting clutch and an engagement drive mode in which the vehicle travels by controlling the torque of the drive source and completely engaging the starting clutch, the torque of the inertia component of the drive source side is deducted from the target drive torque set on the basis of the acceleration opening degree is set as the starting clutch transfer torque capacity in the slip state.
