초록 ▼

An engine controlling system for a vehicle suitable for use with an automobile. An output reduction control amount setting means sets, when an abnormal condition detection signal of a throttle valve controlling means or a throttle valve control amount setting means is developed and a range detection signal indicates a neutral range, a control amount of an engine output reducing means such that the reduction of the output power of an engine may increase as the engine speed represented by an engine speed detection signal increases. On the other hand, when such abnormal condition detection signal is developed and the range detection signal indicates a running range, the output reduction control amount setting means sets a control amount of the engine output reducing means such that the reduction of the output power of the engine may be decreased as the accelerator pedal operation amount represented by an operation amount detection signal increases. With the system, even an abnormal condition takes place in a throttle valve controlling system, the engine can be adjusted within a predetermined range.

An engine controlling system for a vehicle, comprising: an accelerator pedal of said vehicle, an operation amount detecting means for detecting an operation amount of said accelerator pedal and developing a corresponding operation amount detection signal, a throttle valve for changing an amount of air to be taken into an engine of said vehicle to adjust an output power of said engine, a throttle valve control amount setting means for setting a control amount of said throttle valve in response to the operation amount detection signal, a throttle valve controlling means for controlling said throttle valve to open or close in response to the control amount, an abnormal condition detecting means for detecting an abnormal condition of at least one of said throttle valve controlling means and said throttle valve control amount setting means and developing a corresponding abnormal condition detection signal, a speed change gear means provided in said vehicle and having a plurality of gear positions, an automatic speed change gear controlling means for controlling changing over between the gear positions of said speed change gear means, a range changing over means for selectively setting a range of said speed change gear means at least to a running range or neutral range, a range detecting means for detecting a range set by said range changing over means and developing a corresponding range detection signal, an engine speed detecting means for detecting a rotational speed of said engine and developing a corresponding engine speed detection signal, an engine output reducing means for reducing the output power of said engine independently of said throttle valve, and an output reduction control amount setting means for setting, when the abnormal condition detection signal is developed and the range detection signal indicates the neutral range, a control amount of said engine output reducing means such that a reduction of the output power of said engine is increased as the engine speed represented by the engine speed detection signal increases, but setting, when the abnormal condition detection signal is developed and the range detection signal indicates the running range, a control amount of said engine output reducing means such that the reduction of the output power of said engine is decreased as the accelerator pedal operation amount represented by the operation amount detection signal increases.
