    • An apparatus which can accurately detect a state in a passenger compartment is provided. On the ceiling of a passenger compartment above the passenger seat, nine LEDs and three photodetectors are aimed downward, and infrared rays emitted from the LEDs are reflected by an object to be sensed and the reflected light beams are received by the photodetectors. A signal at a level corresponding to the distance to the object to be sensed is outputted from the photodetectors. A controller obtains a change with time in output of the photodetectors (i.e., motion speed from a differential value of the sensed distance, a displacement amount total from an integral value of the sensed distance, and a motion frequency), senses movement of the object to be sensed based thereon, determines whether the object to be sensed is a human, an animal, or other, and determines the kind of object. The controller then transmits a signal indicative of a result of the determination of the object to be sensed which is used to control how the vehicle's air bag is inflated.

    • An internal combustion engine has an exhaust system and an oxygen sensor fitted to the exhaust system including a sensor element and an electrically powered heater for heating the sensor element. A method for controlling the electrical power supplied to the heater properly and quickly heats up the sensor element after engine starting from the cold condition. At the time of starting up the engine it is determined whether or not the temperature of the engine is less than a certain value. If so, the heater is provided with electrical power to the maximum practicable amount, for a certain time interval after the engine is started up. Thereby, during engine heating up operation, the temperature of the sensor element is brought up to its minimum proper operating temperature as quickly as practicable, and accordingly it is ensured that engine performance and the quality of exhaust gas emissions at the time of such engine warming up operation are good. A system is also described for implementing this method.

    • In conventional electronic fuel injection systems, the flow rate of a fuel supply is fixed during a starting operation irrespective of time variations in the running parameters of an internal combustion engine. In accordance with the disclosed method and apparatus of the invention, however, the fuel supply flow rate is controlled in accordance with the time variations in the engine running parameters in the same manner as occurs after the starting operation, that is, during normal engine running operations, when at least one of the engine operating conditions of r.p.m. being higher than a preset level and flow rate of intake air being higher than a preset level is satisfied. Thus, the engine running operations either at a higher engine r.p.m. or at a higher intake air flow rate during the engine starting period can be stabilized while improving the engine startability and smoothing the engine running operations when an ignition switch is returned from its starting to its "on" position.
    • 在传统的电子燃料喷射系统中,燃料供给的流量在启动操作期间是固定的,而与内燃机的运行参数的时间变化无关​​。 然而,根据本发明的公开的方法和装置,燃料供给流量根据发动机运转参数的时间变化以与启动操作之后相同的方式来控制,即在正常的发动机运行期间 当至少有一个发动机工作条件为rpm时 高于预设水平,并且进气的流量高于预设水平。 因此,发动机运行操作在较高的发动机r.p.m。 或者在发动机起动期间以较高的进气流量可以稳定,同时在点火开关从其起始位置返回到其“开”位置的同时提高发动机起动性和平滑发动机运行操作。
