Abstract
A storage unit provided in an engine control device stores three kinds of mode maps having different engine output characteristics. One of the mode maps is selected in accordance with the driving conditions, and a target torque is set by referring to the selected mode map using an engine speed and an accelerator opening-degree as parameters. A throttle opening-degree signal corresponding to the target torque is output to a throttle actuator, and an operation of opening or closing the throttle valve is performed in response to the throttle opening-degree signal.
Claims12
An engine control apparatus, comprising:
- driving-state detection means for detecting a driving state;
- storage means for storing mode maps for respective engine control modes, the engine control modes including at least a power mode having engine output characteristics that prioritize power and a save mode having engine output characteristics with which power is suppressed, each mode map having lattice axes of an accelerator opening-degree and the driving state and setting an engine output command value for the corresponding engine control mode;
- selecting means for selecting one of the engine control modes;
- and
- engine-output-command-value determining means for determining the engine output command value by referring to the mode map corresponding to the engine control mode selected by the selecting means.
An engine control apparatus, comprising:
- driving-state detection means for detecting a driving state;
- storage means for storing mode maps for respective engine control modes, the engine control modes including at least a normal mode having engine output characteristics suitable for normal driving and a power mode having engine output characteristics that prioritize power, each mode map having lattice axes of an accelerator opening-degree and the driving state and setting an engine output command value for the corresponding engine control mode;
- selecting means for selecting one of the engine control modes;
- and
- engine-output-command-value determining means for determining the engine output command value by referring to the mode map corresponding to the engine control mode selected by the selecting means.
