CONTROL APPARATUS FOR HYBRID VEHICLE

摘要

A control apparatus is applied to a hybrid vehicle. The hybrid vehicle includes an MG which is connected with an input shaft of a manual transmission via a first clutch that is operated by a press operation to a clutch pedal and an internal combustion engine which is connected with the MG via a second clutch. The hybrid vehicle is allowed to execute an EV traveling mode where: the internal combustion engine is stopped; the internal combustion engine and drive wheels are separated by the second clutch; and the drive wheels are driven by the MG. In the control apparatus, when the EV traveling mode is executed, a required torque is obtained based on an accelerator opening degree, and a required transmission torque is obtained based on an operation amount to the clutch pedal. And, when a smaller one of the required torque and the required transmission torque is greater than a determination value, the internal combustion engine is started.

1. A control apparatus which is applied to a hybrid vehicle,
the hybrid vehicle having an internal combustion engine and an electric motor as driving sources for traveling, and a power transmission control device, the power transmission control device: being allowed to be operated with a clutch pedal; being provided in a power transmission path lying between the internal combustion engine and a drive wheel; and being allowed to shut off a power transmission between the internal combustion engine and the drive wheel, the electric motor being provided so as to make the drive wheel drive even when the power transmission control device shuts off the power transmission between the internal combustion engine and the drive wheel, and the hybrid vehicle being allowed to execute an EV traveling mode where: the internal combustion engine is stopped; the power transmission between the internal combustion engine and the drive wheel is shut off; and the drive wheel is driven by the electric motor, wherein the control apparatus controls the internal combustion engine, and the control apparatus is programmed so as to include torque obtaining programming instructions to obtain, when the EV traveling mode is being executed, a required torque which is required to the vehicle based on an accelerator opening degree of the vehicle and obtain a required transmission torque which is to be transmitted via the power transmission control device based on an operation amount of the clutch pedal, required value setting programming instructions to set a required value to the required transmission torque when the required torque is greater than the required transmission torque, and set the required value to the required torque when the required torque is equal to or less than the required transmission torque, and starting control programming instructions to start the internal combustion engine when the required value that has been set by the required value setting programming instructions is greater than a predetermined determination value.
