Abstract
A hybrid vehicle including an engine, a generator motor, an output shaft connected to a drive wheel, a differential gear device including at least three gear elements that are connected to the engine, the generator motor and the output shaft, respectively; a fixing device that mechanically fixes a rotation of the generator motor; and a controller that calculates a correction value partially based on a generator motor torque and corrects an engine torque by the correction value.
Claims23
A hybrid vehicle, comprising:
- an engine;
- a generator motor;
- an output shaft connected to a drive wheel;
- a differential gear device including at least three gear elements that are connected to the engine, the generator motor and the output shaft, respectively;
- and
- a fixing device that mechanically fixes a rotation of the generator motor;
- and
- a controller that:
- calculates a correction value partially based on a generator motor torque;
- and
- corrects an estimated engine torque by the correction value, wherein the controller sets the generator motor torque to an initial torque to correspond to a corrected estimated engine torque at a release time of the fixing device.
A hybrid vehicle, comprising:
- an engine;
- a generator motor;
- an output shaft connected to a drive wheel;
- a differential gear device including at least three gear elements that are connected to the engine, the generator motor and the output shaft, respectively;
- and
- a controller that:
- calculates a correction value partially based on a generator motor torque;
- and
- corrects an estimated engine torque by the correction value, wherein the correction value is calculated by averaging a plurality of variation values.
A control method of a hybrid vehicle including an engine, a generator motor, and a fixing device that mechanically fixes a rotation of the generator motor, the control method comprising:
- calculating a correction value partially based on a generator motor torque;
- and
- correcting an estimated engine torque by the correction value, wherein the generator motor torque is set to an initial torque to correspond to a corrected estimated engine torque at a release time of the fixing device.
A control method of a hybrid vehicle including an engine, and a generator motor, the control method comprising:
- calculating a correction value based on an estimated engine torque and a generator motor torque;
- and
- correcting the estimated engine torque by the correction value, wherein the correction value is calculated by averaging a plurality of variation values.
