Abstract: PROBLEM TO BE SOLVED: To provide a start controller for an internal combustion engine capable of efficiently reducing rotary reaction force of an engine output shaft at the start of the engine. SOLUTION: An electronic control unit 20 retards the closing timing of an inlet valve through a variable valve timing mechanism 11 at restarting and reduces an actual compression ratio to reduce a load on a generator motor 17 unavoidable for rotating a crankshaft 12 at restarting. At the same time the electronic control unit 20 estimates the rotary reaction force during restarting, and when the estimated rotary reaction force is small, the closing timing of the inlet valve is prohibited from being retarded and a reducing amount of the actual compression ratio during restarting is set smaller comparing to the case of the large rotary reaction force.

Abstract: PROBLEM TO BE SOLVED: To determine the suitability of the ignition timing of an internal combustion engine implemented in promoting the warming-up of a purifying device (catalyst) for purifying the exhaust gas of the internal combustion engine. SOLUTION: When the engine is started by a motor generator, the temperature of exhaust gas is raised by adjusting an ignition advance angle F to a lag side to warm up the purifying device (S102). After the adjustment of the ignition advance angle F, an engine torque Te outputted from the engine is calculated on the basis of reaction torque acting upon the motor generator (S108) and it is determined whether or not engine torque Te is smaller than criterion torque Tref preset corresponding to an engine speed and an intake air amount (S112), and the engine torque reaches the criterion torque Tref or higher, it is determined that ignition timing adjustment has some failure to turn on a warning lamp (S118). Engine output torque and ignition timing have fixed relations, therefore the suitability of the ignition timing adjustment can be determined by monitoring the output torque.

Abstract: PROBLEM TO BE SOLVED: To provide a motor operated valve control system for controlling driving electric power for a three-way change-over valve particularly at extremely low temperatures in a warm-up stroke of an internal combustion engine.
SOLUTION: The motor operated valve control system determines that the three-way change-over valve is frozen when the temperature of cooling water is not higher than a predetermined value (Y of S16), and the working condition of the three-way change-over valve after a predetermined time elapsed after voltage supply starting does not reach a predetermined state (Y of S20), it is determined that the three-way change-over valve is frozen. When it is determined the freezing, a driving voltage is stopped to be supplied to the three-way change-over valve (S22). This enables the three-way change-over valve to avoid the risk of damage. An operator is informed to check the concentration of an anti-freezing solution in cooling water (S24) so that an incentive to maintenance can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide a warm-up accelerating system allowing easy recognition of proceedings of a warm-up stroke and a heat storage stroke.
SOLUTION: The warm-up accelerating system displays graphics showing the proceedings of the warm-up stroke and the heat storage stroke on a display. With the expression of the proceedings in color variation, a driver easily recognizes the operated conditions of the warm-up accelerating system. Since the graphics are changed corresponding to the operated conditions of the warm-up accelerating system, the driver can wait for finishing the warm-up stroke with a good view thereof.

Abstract: PROBLEM TO BE SOLVED: To increase a chance of diagnosing a failure in a fuel system.SOLUTION: A parameter is updated during execution of air-fuel ratio control for controlling an air-fuel ratio to a target air-fuel ratio, and is related to the air-fuel ratio control showing the failure in the fuel system in which the air-fuel ratio is richer than the target air-fuel ratio during the execution of the air-fuel ratio control. It is diagnosed that a failure occurs in the fuel system when the parameter reaches a predetermined value, and the air-fuel ratio control is stopped when a fuel injection amount reaches the minimum fuel injection amount during the execution of the air-fuel ratio control. Even if the fuel injection amount reaches the minimum fuel injection amount during the execution of the air-fuel ratio control and then the air-fuel ratio control is stopped, a value of the parameter is maintained.

Abstract: PROBLEM TO BE SOLVED: To facilitate start of a variable valve timing mechanism when an engine is driven.SOLUTION: When an oil temperature Toil of a lubrication system for the engine is a predetermined temperature threshold Tref or more, the engine, the variable valve timing mechanism and two motors are controlled so that the engine is operated by a driving point based on a required power Pe* corresponding to a required torque Tr* and an operation line for high oil temperature where the engine rotation tends to be higher than a fuel optimal operation line, and the vehicle travels with the required torque Tr*. Thus, even when the hydraulic pressure is not likely to increase by rotary drive of a mechanical pump since the oil viscosity is high due to high temperature when the oil temperature Toil is the temperature threshold Tref or higher, the engine rotation can be increased and locking by a lock pin in the variable valve timing mechanism is easily released. As a result, the variable valve timing mechanism can be easily started when the engine is driven.

Abstract: PROBLEM TO BE SOLVED: To provide a battery temperature conditioning device capable of preferentially heating a battery cell arranged at both ends at the time of warming up.
SOLUTION: The battery temperature conditioning device has a housing case and battery cells. The battery cells are arranged in the housing case at prescribed spacings. Passages in which a temperature conditioning medium flows are formed between the battery cells and between the battery cell and the inner wall of the housing case. The direction in which the battery cells are arranged and the direction (flowing direction) in which the temperature conditioning medium flows into the housing case are perpendicular. Further, the temperature conditioning medium flowing part supplies the temperature conditioning medium flowed into the housing case into the passages adjacent to the battery cells at both the ends in the arrangement direction out of a plurality of passages. Thereby, the battery temperature conditioning device warms up the battery cells at both the ends positively and preferentially.
