摘要: If it is determined that a brake pedal is pressed while an accelerator pedal is pressed, accelerator position limit control for bringing an accelerator position for engine control to a limit value corresponding to vehicle speed is performed, thereby securing safety at the time when both of the accelerator pedal and the brake pedal are pressed. If it is determined that the accelerator pedal is pressed after the brake pedal is pressed, the accelerator position limit control is prohibited, thereby responding to driver's intention to accelerate. If it is determined that the pressing of the brake pedal is cancelled during execution of the accelerator position limit control, accelerator position recovery control for returning the accelerator position for the engine control to an actual accelerator position is performed, thereby recovering normal running corresponding to the driver's intention to accelerate.
摘要翻译: 如果确定在加速踏板被按压时按下制动踏板,则执行用于将用于引擎控制的加速器位置引导到与车速相对应的极限值的加速器位置限制控制,由此在两者 加速踏板和制动踏板被按下。 如果在按下制动踏板之后确定加速踏板被按下,则加速器位置限制控制被禁止,从而响应驾驶员加速的意图。 如果在执行加速器位置限制控制期间确定取消了制动踏板的按压,则执行将用于将发动机控制的加速器位置返回到实际加速器位置的加速器位置恢复控制,从而恢复对应于 司机的意图加速。

摘要: An engine speed variation after one power stroke from a misfire has an opposite sign (plus or minus) relative to an engine speed variation at a misfire. A computer determines whether the misfire exists in the subject cylinder based on the engine speed variation between the subject cylinder and the subject cylinder after one power stroke. In order to detect any kinds of misfire, the computer computes a difference value between a current engine speed variation and an engine speed variation before 360° CA or after 360° CA, a difference value between a current engine speed variation and an engine speed variation before 720° CA or after 720° CA, and a difference value between a current engine speed variation and an engine speed variation before 720/(cylinder number)° CA or after 720/(cylinder number)° CA. These three difference values are respectively compared with a misfire determination value to perform a misfire detection.
