VEHICLE CONTROL APPARATUS

摘要

A vehicle is equipped with an internal combustion engine having a forced-induction apparatus with variable boost pressure, a first motor generator for generating electricity while applying negative torque to the engine, and a battery for storing the electricity generated by the first motor generator. During the operation of the engine, a target boost pressure is set lower as the rotational speed of the first motor generator is increased. The engine is controlled such that, with the boost pressure adjusted to the target boost pressure, the output torque of the engine has a required value determined by the accelerator operation amount. Further, while the output torque of the engine is adjusted to the required value, the magnitude of the negative torque by the first motor generator acting on the engine is adjusted such that the engine rotational speed has a target value.

1. A control apparatus for a vehicle that includes an internal combustion engine with a forced-induction apparatus, an electric motor-generator that generates electricity while applying negative torque to the engine, and a battery in which electricity generated by the electric motor-generator is stored, wherein
the forced-induction apparatus includes a forced-induction device and a variable boost pressure mechanism that varies boost pressure caused by the forced-induction device, the control apparatus sets a required value of output torque of the engine in accordance with an accelerator operation amount, the control apparatus controls the variable boost pressure mechanism such that the boost pressure is adjusted to coincide with a target boost pressure that is set based on an operation state of the internal combustion engine, the control apparatus further comprises a controller, the higher rotation speed of the electric motor-generator, the lower the target boost pressure set by the controller becomes, in a state where the boost pressure is made to match with the target boost pressure, the controller controls the internal combustion engine such that output torque of the internal combustion engine becomes equal to the required value, which is determined by the accelerator operation amount.
