PROBLEM TO BE SOLVED: To prevent a vehicle from traveling regardless of owner's intention. SOLUTION: An owner of the vehicle or a vehicle use-right holder authorized by the owner on the use of the vehicle has a travel un-authorizing signal receiving means for receiving the un-authorization of the travel of the vehicle and a driving control state changing means for changing the driving condition of the vehicle based on it. By performing driving force restriction and shift restriction of the vehicle, for example, the travel of the vehicle against the owner's intention is restricted, and the vehicle is prevented from being stolen.

PROBLEM TO BE SOLVED: To cool an electricity-accumulating mechanism mounted on a vehicle without causing a time lag with temperature rise. SOLUTION: A battery ECU executes a program that includes a step (S100) in which the battery temperature TB is detected; a step (S400) in which, if the battery temperature TB becomes higher than a threshold value TH(Lo) of a battery cooling fan actuation starting temperature (YES at S300) when a sports mode is selected (YES at S200), a battery cooling fan is actuated; and a step (S400) in which, if the battery temperature TB becomes higher than a threshold value TH(Hi) of the battery cooling fan actuation starting temperature (YES at S500) when a sports mode is selected (NO at S200), the battery cooling fan is actuated.

PROBLEM TO BE SOLVED: To prevent exhaustion of gases which exceeds the cleaning capacity of a catalyst during warming up of vehicle. SOLUTION: The control method for a vehicle includes a step (S106) where a vehicle is run in an EV travel mode in accordance with operation of a driver, a step (S115) for executing warming up of the vehicle travel, if warming up is determined as being required, and a step (S118) which prohibits EV traveling mode so as to allow the warming up travel of the vehicle.

PROBLEM TO BE SOLVED: To improve energy efficiency of an apparatus by operating an internal combustion engine provided in a power output apparatus corresponding to states of the power output apparatus. SOLUTION: This hybrid vehicle, which torque-converts the power from the engine with an epicyclic gear mechanism and two motors connected with a rotating element of the epicyclic gear mechanism and outputs the torque-converted value to a driving shaft connected with a driving wheel, stores a plurality of different operation lines LP, L0 to L3 with a constraint of different conditions for power outputted from the engine, and operates the engine and controls driving of the two motors by establishing the operation lines corresponding to a vehicle speed and motor conditions, thus improving energy efficiency of a vehicle and accommodating the output limit of an apparatus such as a motor.

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. COPYRIGHT: (C)2004,JPO
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 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.
