摘要： A malfunction determination apparatus for a cooling apparatus that cools an internal combustion engine by circulating a coolant through an interior of the internal combustion engine, using an electric pump, after the internal combustion engine is started includes: a detection portion that detects the coolant temperature; and a determination portion that determines a malfunction has occurred in a thermostat, if a state in which the detected coolant temperature remains below a first threshold temperature after the electric pump begins operating, following start of the internal combustion engine, continues for at least a pre-determined time. The thermostat is a thermostat for switching from a first passage for circulating the coolant without passage via an interior of a radiator of the cooling apparatus to a second passage for circulating the coolant via the interior of the radiator, as the coolant temperature rises.

摘要： In the case of non-execution of catalyst warm-up acceleration control, the engine misfire detection procedure compares a 30-degree rotation time computed as a time required for a 30-degree rotation of an engine crankshaft with preset reference values Tref1 and Tref2 and distinctly detects the occurrence of intermittent engine misfires and the occurrence of either a single engine misfire or consecutive engine misfires (steps S120 to S150). In the case of execution of the catalyst warm-up acceleration control, the engine misfire detection procedure compares the 30-degree rotation time computed as the time required for a 30-degree rotation of the engine crankshaft with preset reference values Tref3 and Tref4 and distinctly detects the occurrence of the consecutive engine misfires and the occurrence of either the single engine misfire or the intermittent engine misfires (steps S160 to S190). This arrangement ensures accurate detection and identification of engine misfires, regardless of execution or non-execution of the catalyst warm-up acceleration control.

摘要： A delay time for delaying starting of an internal combustion engine in a hybrid vehicle is set to a predetermined time based on an engine coolant temperature and a state of an air conditioner switch. Starting of the engine is delayed for the predetermined time if it is determined that a vehicle can run using only a motor based on a required torque, a required power and an SOC of the battery. The predetermined time is determined based on a time necessary for completing preheating of an engine by a preheating device, preparations of sensors such as an air-furl ratio sensor, and warming-up of an exhaust gas purifying device. As a result, it is possible to efficiently perform start of the engine and operation immediately after the engine start, and to make control at the engine start time simple.
摘要翻译：基于发动机冷却剂温度和空调开关的状态，将混合动力车辆中的内燃机的起动延迟的延迟时间设定为规定时间。如果基于所需的扭矩，所需的电力和SOC的SOC确定车辆可以仅使用电动机运行，则发动机的启动延迟预定时间。基于预热装置对发动机进行预热所需的时间，空气比率传感器等传感器的准备以及排气净化装置的预热来确定预定时间。结果，可以在发动机起动之后立即有效地执行发动机的起动和操作，并且使发动机起动时间的控制变得简单。

摘要： The technique of the invention determines whether input data for driving and controlling a cooling fan have any abnormality (steps S100 and S110), sets an actual drive level F* of the cooling fan to a high level (Hi) in the event of detection of any abnormality (step S130), and controls a fan motor to drive the cooling fan at the set drive level F* (step S140). This arrangement effectively prevents a temperature rise to an abnormally high level in any of an engine and motors even in the event of any abnormality arising in the input data.

摘要： The auto engine start control of the invention regulates a throttle valve to a restricted opening to reduce an air intake flow at an ordinary start of an engine (step S140). When the driver stamps on an accelerator pedal to raise an engine power demand Pe* to or above a preset threshold value Pref, the auto engine start control regulates the throttle valve to a standard opening to ensure the air intake flow corresponding to the engine power demand Pe* (step S150) and thereby cranks the engine. This arrangement desirably dampens potential vibration induced by ignition at the ordinary start of the engine, while ensuring prompt output of the required driving force from the engine under the condition of the higher engine power demand Pe*.
