CONTROL DEVICE FOR HYBRID VEHICLE

摘要

A control device for a hybrid vehicle is configured to enter a driving mode in which a preset engine-start condition is met, and is configured to enter electric vehicle mode when a preset engine-stop condition is met, and includes an engine-start-condition-controlling device which, during travel in the electric vehicle mode, in the event that an electric vehicle travel zone expansion condition that has been set on the basis of vehicle speed VSP and torque demand information reflective of demand by the driver, and that expands the travel zone in the electric vehicle mode, is met, changes the engine-start condition from a baseline start condition, to an expansion engine-start condition for expanding the travel zone in the electric vehicle mode, doing so for the duration of a prescribed time thereafter.

主权项

1. A control device for a hybrid vehicle, the hybrid vehicle including an engine, a motor for a drive system extending from the engine to a drive wheel and for starting the engine and driving the drive wheel, and a mode switching device configured to bring about a hybrid vehicle mode in which rotation of the motor is transmitted to the engine when a preset engine-start condition is met and the engine is started so that the engine and the motor serve as drive sources, and being configured to stop the engine and bring about an electric vehicle mode in which the motor serves as the drive source when a preset engine-stop condition is met, the mode switching device being provided to a part linking the engine and the motor, the control device comprising:
an engine-start-condition-controlling device programmed to cause the engine-start condition to be changed when the vehicle is traveling in electric vehicle mode and an electric vehicle travel zone expansion condition is met for a prescribed time after the electric vehicle travel zone expansion condition has been met, from a baseline start condition that prevails when the electric vehicle travel zone expansion condition is not met to an expansion engine-start condition for expanding the travel zone in the electric vehicle mode, the electric vehicle travel zone expansion condition being set on the basis of vehicle speed and torque demand information reflective of demand by a driver, and the travel zone in the electric vehicle mode being expanded under the electric vehicle travel zone expansion condition.
