    摘要: When a specified learning executing condition is established, a command furl injection quantity ratio (CFIQ-ratio) between two fuel injectors is compulsorily changed and a fuel injection quantity error of each fuel injector is learned respectively based on the CFIQ-ratio and an air-fuel-ratio feedback correction value. Based on the learning value of fuel injection quantity error, a fuel injection period of each fuel injector is respectively corrected, whereby each fuel injection quantity error of two fuel injectors is respectively corrected with respect to each cylinder. Thereby, a ratio of fuel injection quantity between two fuel injectors is accurately controlled.

    摘要: When the driving wind and the cooling wind are generated, based on the phenomenon in which the temperature difference is generated between the front surface and the rear surface of the radiator (14), the temperature difference between the detection value of the rear temperature sensor (22) and the detection value of the front temperature sensor (21) is compared with the abnormality determination value so that it is determined whether the front temperature sensor (21) and the rear temperature sensor (22) are properly fixed on the radiator (14), whereby it is determined whether the abnormality (unauthorized alteration) exists. By setting the abnormality determination value according to the ambient temperature and the vehicle speed, corresponding to a variation in temperature difference between the front surface and the rear surface of the radiator (14), the abnormality determination value is varied to be set at a proper value.

    摘要: When a computer determines that an accelerator pedal and a brake pedal are simultaneously stepped based on the signals from the accelerator position sensor and a brake switch, the first switch is turned off so that the accelerator sensor signal which will be transmitted into the computer is compulsorily made zero. A throttle-position command value which will be transmitted from the computer into a throttle actuator is reduced to a value corresponding to the idling state. If an engine output is not reduced, the computer turns off a second switch so that a throttle actuator is de-energized. A throttle valve is compulsorily brought into a position corresponding to an idling state by a biasing force of a throttle return spring.
