Abstract
The control apparatus executes a pulsation compensating control where pulsation compensating torque is calculated for suppressing torque pulsation of an internal combustion engine by a pulsation-compensating-torque calculating portion and an MG1 controlling portion controls a first motor generator to output the pulsation compensating torque, while executes a pressing control where pressing torque is calculated for preventing torque of a second motor generator from crossing 0 Nm by a pressing-torque calculating portion and an MG2 controlling portion controls the second motor generator to output the pressing torque.
Claims5
A control apparatus for a hybrid vehicle, the hybrid vehicle having a first electric motor and a second electric motor on a power transmission path for transmitting output of an internal combustion engine to drive wheels, the second electric motor being connected to the power transmission path with a backlash existing therebetween, wherein
- the control apparatus is configured as a computer, and by executing a computer program, configured to execute:
- a pulsation compensating control in which the first electric motor is controlled to output pulsation compensating torque for suppressing torque pulsation of the internal combustion engine;
- and a pressing control in which the second electric motor is controlled to output pressing torque for preventing motor torque of the second electric motor, which is transmitted to the power transmission path, from crossing 0 Nm.
