Abstract:
A control apparatus for a hybrid vehicle with an internal combustion engine and a motor/generator connected to the internal combustion engine used as a driving source, an automatic transmission connected to the driving source, axles connected to the automatic transmission, and a sensor for detecting a running state of the vehicle, comprising:a controller that: judges whether the vehicle is running on a congested road based on an output from the sensor; causes a take-off from a first state where a gear ratio of the automatic transmission is large at a time of taking-off when running on the congested road; causes the take-off from a second state where the gear ratio of the automatic transmission is small at the time of taking-off when not running on the congested road; and replenishes, by driving the motor/generator, a part of an under torque of the driving source created by taking-off from a state where the gear ratio of the automatic transmission is large, when a temporary high acceleration take-off request is made while a judgment of congested road running is maintained.
