摘要： Methods and systems for monitoring engine coolant temperature sensors are described. In one embodiment, an expected engine coolant temperature may be determined based on the accumulated engine mass air flow. If the current engine coolant temperature is substantially different from the expected temperature, then an error signal may be generated. In one embodiment, the expected engine coolant temperature is compared to the actual engine coolant temperature if the engine coolant temperature has changed by a predetermined amount. In one embodiment, the expected engine coolant temperature is compared to the actual engine coolant temperature if the accumulated engine mass air flow is equal to or is greater than a predetermined value.
摘要翻译： 描述了用于监控发动机冷却剂温度传感器的方法和系统。 在一个实施例中，可以基于累积的发动机质量空气流量来确定预期的发动机冷却剂温度。 如果当前发动机冷却剂温度与预期温度基本上不同，则可能产生误差信号。 在一个实施例中，如果发动机冷却剂温度已经改变预定量，则将预期的发动机冷却剂温度与实际的发动机冷却剂温度进行比较。 在一个实施例中，如果累积的发动机质量空气流量等于或大于预定值，则将预期的发动机冷却剂温度与实际的发动机冷却剂温度进行比较。

摘要： A system and method of compensating for torque converter slip in a motor vehicle include measuring rotational speeds of an engine crankshaft and mainshaft, as well as measuring operating temperatures of a fluid associated with the motor vehicle. Engine output torque is adjusted as required by controlling some combination of ignition timing, intake air flow, fuel injection, and accessory load.

摘要： An engine control system and method for controlling engine air flow during a deceleration fuel cut includes an internal combustion engine, an anti-lock braking system (ABS), and an electronic control unit (ECU) that controls the engine. The ECU establishes a desired air flow rate for the internal combustion engine, which is taken from an ABS failed condition look-up table when determined that the ABS has failed while the engine is in a deceleration fuel cut mode, and otherwise is taken from a normal condition look-up table.

摘要： A method of controlling an engine during starting is disclosed. During cold starting and following a refueling, a default alcohol value is used to control various systems associated with the engine, including fuel injection and ignition timing. The default alcohol value is used to ensure reliable starting. During non-cold starting and following a refueling, the current alcohol value is used to minimize fuel inefficiencies.
