Abstract
To avoid the undesired processing of a failure, a first target throttle opening is obtained from an accelerator opening, a second target throttle opening is obtained by adding the accelerator opening and a control value equivalent to the amount of bypass air, and the second target throttle opening is output when the first target throttle opening is larger than the second target throttle opening because the first target throttle opening is a computed abnormal value.
Claims6
A car engine controller comprising:
- means for electrically computing a throttle opening based on a detected accelerator opening;
- means for computing a control variable by adding a control value and a value of the detected accelerator opening;
- and
- means for controlling a throttle actuator based on the computed throttle opening when the computed throttle opening is smaller than the control variable, and controlling the throttle actuator based on the control variable when the computed throttle opening is larger than the control variable.
A car engine controller for controlling a throttle actuator based on a throttle opening which is electrically computed based on a detected accelerator opening and a detected throttle opening, the controller comprising:
- input means for receiving signals for the detected accelerator opening and the throttle opening;
- means for switching a burn mode of an engine to a lean burn mode when a difference between the accelerator opening and the throttle opening is greater than a predetermined amount.
