摘要： A cruise control apparatus for a vehicle is effective to prevent hunting in the vehicle speed and resultant shocks which are apt to occur when the vehicle is travelling on a down slope under cruise control. A cruise control unit is adapted to be actuated by a driver of the vehicle for automatically controlling the opening degree of a throttle valve so that the speed of the vehicle is maintained at a predetermined target speed. A fuel control unit controls the fuel supply to the vehicle engine such that the fuel supply is cut off when the throttle valve is moved to a fully closed or idling position thereof with the number of revolutions per minute of the engine being equal to or greater than a predetermined value during cruise control. In one aspect, the fuel cut-off is cancelled when the speed of the vehicle decreases below a predetermined lower limit for the target speed during cruise control, and at the same time, the cruise control is temporarily interrupted for a predetermined length of time. In another aspect, the cut-off of the fuel supply by the fuel control unit is inhibited when the vehicle is travelling under cruise control.

摘要： A misfire detection device for an internal combustion engine determines the time length tx from each ignition timing, as determined by the ignition signal Se, to a predetermined angle of the crank shaft after the ignition timing as determined by the crank angle pulse signal Sd. When the difference between the current and the preceding time lengths thus determined exceeds a reference level, an occurrence of misfire is detected. Alternatively, when the difference .DELTA..omega.d between the instantaneous angular velocities immediately after the ignition timing and a predetermined angle thereafter as determined on the basis of the crank angle pulse signal Sd is less than a predetermined reference level, an occurrence of misfire is detected.

摘要： An apparatus for controlling air supply to an internal combustion engine comprises a main intake pipe for supplying air to the engine, a throttle valve disposed in the main intake pipe for controlling flow rate of the air supplied to the engine in dependence on depression of an accelerator pedal, a plurality of bypass passages disposed in parallel with the main intake pipe for allowing the air to be supplied to the engine by bypassing the throttle valve, a plurality of bypass valves installed in the plurality of bypass passages, respectively, a diagnosis means for diagnosing the throttle valve and devices associated therewith as to occurrence of abnormality, and a controller responsive to detection of the abnormality to close the throttle valve while allowing the bypass valves to control the intake air flow in dependence on depression of the accelerator pedal. The controller responds to detection of the abnormality for shifting a range of engine operation from a normal operation range. Besides, upon occurrence of abnormality in the throttle valve and the associated devices, the controller converts the opening degree of the bypass valves determined arithmetically on the basis of a driving force required for driving the bypass valves into a corresponding opening degree of the throttle valve, and controls the speed of the motor vehicle and a fuel supply to the engine on the basis of the converted opening degree. A limp-homing operation of the motor vehicle can be ensured.
