Vehicle control device

A vehicle control device that controls an injector capable of multistage injections that directly injects fuel into a combustion chamber of an internal combustion engine, the vehicle control device comprising:

• a control unit configured to reduce the number of multistage injections in one cycle in a case where a temperature of the fuel injected from the injector is within a set high temperature region and a pressure of the combustion chamber is within a set low pressure region,
• wherein a temperature sensor is configured to determine the temperature of the fuel injected from the injector, and the determined temperature of the fuel injected from the injector is sent to the control unit, and
• wherein a pressure sensor is disposed in an intake port to the combustion chamber and is configured to measure a pressure of the intake port, and the measured pressure of the intake port is sent to the control unit in order to estimate the pressure of the combustion chamber.

A vehicle control device that controls an injector that directly injects fuel into a combustion chamber of an internal combustion engine, the vehicle control device comprising:

• a control unit configured to increase a peak value of a drive current to the injector in a case where a temperature of the fuel injected from the injector is within a set high temperature region and a pressure of the combustion chamber is within a set low pressure region,
• wherein a temperature sensor is configured to determine the temperature of the fuel injected from the injector, and the determined temperature of the fuel injected from the injector is sent to the control unit, and
• wherein a pressure sensor is disposed in an intake port to the combustion chamber and is configured to measure a pressure of the intake port, and the measured pressure of the intake port is sent to the control unit in order to estimate the pressure of the combustion chamber.
