Abstract
A control apparatus for a vehicle may include an engine, a fuel tank, a feed pump, a pressure sensor, a motor and an electric storage apparatus. The feed pump feeds the fuel to a port injection valve. The pressure sensor detects a fuel pressure that is fed to the port injection valve. The motor performs cranking of the engine at start time of the engine. The control apparatus includes an ECU. The ECU controls the feed pump based on a detection value of the pressure sensor and controls the motor in order to start the engine. The ECU controls the feed pump and the motor such that the electric storage apparatus feeds electric power to the motor in preference to the feed pump, when an electric power that the electric storage apparatus is able to output at the start time of the engine is less than a determination threshold.
Claims5
A control apparatus for a vehicle, the vehicle including:
- an internal combustion engine including a port injection valve, the port injection valve being configured to inject fuel into an intake passage of the internal combustion engine;
- a fuel tank for storing the fuel;
- an electric feed pump configured to suck the fuel from the fuel tank and feed the fuel to the port injection valve;
- a fuel pressure sensor configured to detect a pressure of the fuel that is fed to the port injection valve;
- a motor configured to perform cranking of the internal combustion engine at a start time of the internal combustion engine;
- and
- an electric storage apparatus configured to feed electric power to the electric feed pump and the motor,
- the control apparatus comprising
- at least one electronic control unit programmed to:
- control the electric feed pump based on a detection value of the fuel pressure sensor;
- control the motor in order to start the internal combustion engine;
- and
- control the electric feed pump and the motor to cause the electric storage apparatus to feed electric power to the motor in preference to the electric feed pump, when a first electric power is less than a determination threshold, the first electric power being an electric power that the electric storage apparatus is able to output at the start time of the internal combustion engine.
