摘要:
When there is no malfunction in either drive shaft rotational speed detection portion (36) or rotating shaft rotational speed detection portion (44), control of internal combustion engine (22), the power split device (30, MG1), the electric motor (MG2), and the shifting portion (60) is performed while speed ratio in shifting portion (60) is changed and an intermittent operation of internal combustion engine (22) is performed so that a drive power required for drive shaft (32a) is output to shaft (32a). When a malfunction occurs in drive shaft rotational speed detection portion (36) or/and rotating shaft rotational speed detection portion (44), the control is performed while at least one of change in speed ratio, intermittent operation, and output of drive power required for shaft (32a) to shaft (32a) is limited so that a drive power that approximates required drive power as closely as possible is output to drive shaft (32a).

In a drive system, where power from a motor is transmitted to a drive shaft and a transmission ratio is changed by a transmission, if the absolute value of the difference between the reference torque Tm2r0, which is the drive shaft side torque Tm2r at the onset of a change in the shift speed of the transmission, and the driving shaft side torque Tm2r during the change is less than the threshold value α until the end of the change (S280), the application state of a brake in the transmission during the change and the state of the hydraulic pressure supplied to the brake are learned (S290). During the change, and actuator of the transmission is controlled using those learned results. Accordingly, any deviations that may have occurred due to changes over time in the transmission, etc. are corrected and the shift speed of the transmission is changed more appropriately.

In a motor vehicle having a planetary gear mechanism linked to an engine, a first motor, and a drive shaft and having a second motor attached to the drive shaft via a transmission, in a Lo gear position of the transmission, the control procedure of the invention drives the engine intermittently corresponding to a preset engine power demand Pe* (steps S170 and S230). In a Hi gear position of the transmission, the control procedure keeps the engine in load operation (step S330). When a relatively large driving force is required in the Hi gear position of the transmission, the drive control of the invention enables quicker output of the required driving force to the drive shaft, compared with the output of the driving force from the operation stop state of the engine.
摘要:
A power output apparatus that suppresses wearing-out of the components of a transmission connected to a drive shaft and a rotating shaft of an electric motor as well as reducing the a shock imparted to the vehicle. The required drive power is output to the drive shaft by appropriately controlling and internal combustion engine, a power split device, the electric motor and a shifting portion. When the rotational speed of the drive shaft can be estimated, the speed ratio in the shifting portion is changed based on either the detected rotational speed of the drive shaft or the estimated rotational speed of the drive shaft and the rotational speed of the rotating shaft. However, when the rotational speed of the drive shaft cannot be estimated, the speed ratio is maintained in the shifting portion.

A control device for a vehicle including a motor, an engine, wherein the motor can be drivingly connected with the engine, a torque converter, a transmission mechanism for transmitting the drive torque, which is transmitted via the torque converter from the engine and the motor, to drive wheels, and a controller that controls a driving state of the motor, controls a driving state of the engine, and outputs a torque reduction command for controlling a drive torque of the motor in order to place the drive torque of the motor within a maximum input torque of the transmission mechanism, wherein the maximum input torque is calculated based on a torque ratio of the torque converter when the engine begins driving after the motor begins driving.
摘要:
The controller includes motor control means for controlling the drive RPM of a motor generator to reach a specified RPM less than the idle RPM when the braking condition of a foot brake is detected by a brake-operating-state detecting means while a motor generator is being rotated at an idle RPM or more. This reduces uncomfortable shock which tends to occur because of a change in the rotation of the motor during braking as much as possible to improve drive feeling.
