摘要： Predicting of starting of an engine is performed in advance before starting of the engine. When the starting of the engine is predicted, a failure diagnosis of a device such as a heater, a pump and so forth, which are attached to the engine and to be operated before starting of the engine, is made. When the heater and the pump are determined to be normal from the result of the diagnosis, the heater and the pump are operated before the engine is started. With this, the temperature of the heater can be increased and the pressure of a fluid carried by the pump can be increased before starting the starting of the engine.

摘要： A leak diagnosing technology in which a diagnostic space capable of being closed is defined which includes therein a fuel tank and a canister, the closed diagnostic space being pressurized by an air pump to diagnose of presence or absence of a leak in the diagnostic space based on whether or not a pressure in the diagnostic space indicates a predetermined pressure change. When the diagnosis is completed, the air pump is reversely rotated to cause a reduction in the pressure in the diagnostic space to thereby quickly return the pressure to a target pressure in a steady state.

摘要： Factors affecting the response time of a transfer system from the combustion of injected fuel to the detection of its oxygen concentration include a stroke delay time due to an engine speed, the dependence of an LAF sensor response time on an exhaust gas flow rate, a response time change of the LAF sensor due to its deterioration with time, and the like. If a hyperplane of the sliding mode is fixed without considering the above-mentioned factors affecting the response time of the transfer system, an overshoot or oscillation of a feedback system may occur at low speeds of the engine even if preferable feedback responsiveness can be achieved, for example, at high speeds of the engine. This results in aggravated exhaust emissions, degraded drivability due to torque fluctuations, and fluctuations in idle speed.A hyperplane used in a control system for providing feedback control of an air-fuel ratio through sliding mode control is varied based on the factors affecting the response time of the control system within a range in which the control system can be stabilized.
摘要翻译：影响转移系统从燃料燃烧到其氧浓度的响应时间的因素包括由于发动机转速引起的冲程延迟时间，LAF传感器响应时间对废气流量的依赖性，响应 LAF传感器由于其随时间而劣化的时间变化等。如果在考虑到影响传送系统的响应时间的上述因素的情况下固定滑模的超平面，即使可以实现优选的反馈响应，也可能在发动机的低速下发生反馈系统的过冲或振荡，例如，在发动机的高速度。这导致严重的废气排放，由于扭矩波动导致的驾驶性能下降以及怠速速度的波动。在控制系统中用于通过滑动模式控制提供空燃比的反馈控制的超平面基于影响控制系统在其中可以稳定控制系统的范围内的响应时间的因素而变化。
