Abstract: PROBLEM TO BE SOLVED: To solve such a problem that the exhaust heat of an inverter is not collected in a hybrid car. SOLUTION: An ECU for the inverter determines whether the inverter cooling water is collected in a thermal storage tank or not (S10). In a case when the inverter cooling water is collected (Y of S10) in an internal combustion engine stopped state (Y of S12), the ECU for inverter compares a temperature of the engine cooling water with a temperature of the inverter cooling water (S14). The ECU for inverter opens a selector valve (S16), when the temperature of the inverter cooling water is higher (Y of S14). COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a vehicular engine warming-up device capable of improving collecting efficiency of warm water, and having a thermal storage system.
SOLUTION: The vehicular engine warming-up device comprises a heat radiating portion radiating the heat of cooling water, and a heat accumulator 10 storing the cooling water that is warmed up over a specified temperature, in an engine cooling water system. The heat radiation capacity of the heat radiating portion is made to be variable, and when the heat accumulator 10 collects the warm water, the heat radiation capacity of the heat radiating portion is made to be small. The heat radiating portion is a radiator.

Abstract: PROBLEM TO BE SOLVED: To provide a starting device for an internal combustion engine, suppressing the occurrence of great vibration in the internal combustion engine following wastefully increased pressure in a combustion chamber getting into the first compression stroke after starting the engine in a warm-up completed condition.
SOLUTION: At starting the engine in the warm-up completed condition, torque to be granted to a crankshaft 9 for cranking is lowered in a certain period from starting the engine to arriving at the top dead center of the compression stroke. Thus, the torque to be granted to the crankshaft 9 is set to be such a value that the rotation of the crankshaft 9 is stopped in the certain period to make an engine speed into zero. When the rotation of the crankshaft 9 is stopped, a time required for releasing a preset amount of gas from the combustion chamber 2 being in the first compression stroke after starting the engine is accurately kept in the period and pressure in the combustion chamber 2 is lowered. Consequently, there is no wastefully increased pressure in the combustion chamber 2 after resuming the cranking.

Abstract: PROBLEM TO BE SOLVED: To provide a crank angle detection device for an internal combustion engine capable of detecting the rotation angle of the crankshaft of the engine more accurately.
SOLUTION: A crank angle calculating part 38 calculates the estimated value of a crank angle which is the estimated value of the rotation angle of the crankshaft 24 based on a motor angle signal outputted by a motor angle sensor 34 and the rotation ratio set value of the engine 10 which is the internal combustion engine and a starter generator 22 which is a motor. The rotation ratio correction part 40 compares an actual crank angle signal outputted by a crank angle sensor 30 with the estimated value to obtain an error in the value, thereby correcting the set value.

Abstract: PROBLEM TO BE SOLVED: To certainly start an engine. SOLUTION: When the engine does not completely explode within a predetermined time after engine start by driving a starter motor and a fuel pump (S100 to S104), the driving of the fuel pump is stopped for a predetermined time (for example, 3 sec) and is restarted after a predetermined time (S106 to S110). The driving of the fuel pump is temporarily stopped because repeating of driving and stopping of the fuel pump frequently allows removal of a foreign matter even when the foreign matter intrudes into the fuel pump to cause a starting failure. Thus, the fuel pump is normally driven, so that the engine is started further certainly. COPYRIGHT: (C)2004,JPO
Abstract translation: 要解决的问题：一定要启动发动机。 解决方案：通过驱动起动电动机和燃料泵，发动机起动后的发动机未完全爆炸（S100〜S104），燃料泵的驱动停止规定时间（例如， 3秒），并且在预定时间之后重新开始（S106至S110）。 燃料泵的驱动暂时停止，因为即使当异物进入燃料泵而引起启动故障时，重复燃料泵的驱动和停止也频繁地允许除去异物。 因此，燃料泵通常被驱动，使得发动机进一步启动。 版权所有（C）2004，JPO

Abstract: PROBLEM TO BE SOLVED: To determine a desirable method for engine operation in a hybrid car. SOLUTION: An engine 150 is started/stopped by judgment values different depending on a shift range detected by a shift position sensor 184. Judgment values for the start/stop of the engine 150 are set so that the engine 150 may be easier to start especially in PARKING and REVERSE ranges, and by a running condition and SOC of a battery 194 in DRIVE range. Besides, the judgment values in DRIVE range are set to higher values than those in another range in some cases.

Abstract: PURPOSE:To secure engine output for processing a remaining load during the time of its existence and improve fuel consumption, etc., having a large idle up applicable range by increasing the engine output temporarily from a point of time when the engine load is shut out in operation. CONSTITUTION:An idling condition of an internal combustion engine is detected by a means M1. A load applied to the internal combustion engine is detected by a means M2. When the load is applied during the idling time of the internal combustion engine, the output of the internal combustion engine is increased by a first means M3. On the other hand, the operation of the load is detected by a means M4. When the load is cutoff-operated at the idling time of the internal combustion engine, the output thereof is increased by a second means M5 more than the first means M3. The engine output is increased transiently from the point of time when the operation for shutting the engine load is carried out. Consequently, the engine output is secured for processing the remaining load during existence the remaining load.

Abstract: PURPOSE:To control the ignition timing to knocking limit even in case the air-to-fuel ratio varies, by changing the knocking judgment level according to change in the air-to-fuel ratio. CONSTITUTION:In a control circuit 45, the peak value of engine vibrations in a certain crank angle range after agnition is compared with the judgment level on the basis of output of a knocking sensor 36, and the result is used for judgment whether knockings have occurred. Angle delay/advance control of the ignition timing is made on the basis of the result from this judgment. Here the knocking judgment level is changed according to change in the air-too- fuel ratio. Thereby the air-to-fuel ratio is controlled to output air-to-fuel ratio in normal operating condition, and in case the exhaust temp. sensed by an exhaust gas sensor 50 has risen over a certain value, the air-to-fuel ratio is controlled to the richer side for the purpose of protecting the exhaust system, that makes it possible to judge whether any knocking is generated using the same judgment level even in case the background level of engine vibrations has varied.

Abstract: PURPOSE:To prevent shortage in the quantity of fuel supply by controlling the driving force of a fuel pump to be on the high driving force side when the abnormality of microcomputer has occurred in a device in which the driving force of said fuel pump is controlled by said microcomputer in accordance with the operating condition of an engine. CONSTITUTION:When an abnormal condition has occurred in which an H signal as a normal signal at every fixed time (e.g., every 10msec) is not outputted from an ECU 24, the output of a comparator 25 becomes L and a transistor Tr 26 is turned off due to a driving force controlling signal 11. Thereupon, a capacitor 16 is gradually charged and, when the input voltage of a comparator 17 becomes above a reference voltage, the output of the comparator 17 becomes H, turning on a Tr 18 as well as relays 19, 20. Thereby, a Tr 21 is electrified, from a storage battery 15 via relays 14, 20 and turned on, while turning on a relay 22. Accordingly, a high voltage is applied to a fuel pump 2, and a quantity of fuel more than the maximum fuel quantity required by an engine, is fed into a pressure regulator 6.
