Abstract

PURPOSE:To prevent abnormal acceleration from occuring, by judging it as an abnormal state at a time when an accelerator pedal is in nonoperational or a braking pedal is under operation and throttle valve opening is not yet in its minimum opening, while intercepting the fuel feed to a part of cylinders. CONSTITUTION:When trouble happens in a throttle driving control system consisting of an accelerator pedal 1, a pedal step-on extent sensor 2, a function generator 3, a driver 4, an actuator 5, and a throttle valve 6, there is produced such a state that the throttle valve 6 fails to fully close itself regardless of opening the accelerator pedal or stepping on a brake pedal 9. If so, a trouble state judging circuit 11 inputting each signal out of an accelertor open sensor 7, a brake operation sensor 8 and a throttle full-close sensor 10 outputs an H signal. With this constitution, a warning lamp 12 is lighted via an FF22, while each of fuel injection valves 16c and 16d related to No.3 and No.4 cylinders 15c and 15d via drivers 14c and 14d is stopped to operate.

加速を防止することができる。(Effects of the Invention) As is clear from the description of the embodiments above, in the first invention of this application, the state where the accelerator operator is not operated or the state where the brake operator is operated is An abnormal state determining means is provided which determines as an abnormal state when a state in which the throttle opening is detected and the throttle opening is at a predetermined minimum of 1 FIJ degree is not detected, and if an abnormal state is determined, the part of the engine is continuously Fuel supply to the cylinder
This makes it possible to prevent abnormal acceleration caused by an excessive increase in the combustion amount of the entire engine during driving due to the throttle valve opening too much to the open side than the opening command value. can.

加速不足を来たすことがなく運転を継続できる。Further, according to the second invention of this application, a state in which the accelerator operator is not operated is detected and a state in which the IJX throttle opening is at a predetermined minimum opening is not detected as an abnormal state. We have installed an abnormal state determination means to determine the abnormal state, and cut off fuel supply to some cylinders of the engine only during the period when an abnormal state is determined, so when the accelerator is released, some cylinders The fuel supply to the cylinders is cut off, preventing fuel consumption due to wasteful combustion, and at the same time, during acceleration, some of the cylinders G return to the combustion state, so even in such an abnormal state, there is no shortage of acceleration. You can continue driving without causing any problems.
