Abstract: PROBLEM TO BE SOLVED: To provide a controller and a control method for a hybrid vehicle capable of appropriately controlling power requested by an internal combustion engine when the internal combustion engine is started. SOLUTION: A travel control unit 250 selects one of multiple patterns regarding control of engine requested power Pe and controls the engine requested power Pe according to the pattern. The multiple patterns include: a first pattern for generating a requested value accompanying a start of an engine; a second pattern for generating a requested value after the start of the engine while generating no request value during the start of the engine; and a third pattern for generating no request value both during and after the start of the engine. The travel control unit 250 selects either one of the first and the third patterns as a control pattern in an EV mode where an engine basically stops. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To perform much proper control in starting an engine whose operation stops in a vehicle on which an engine and a motor are loaded, and to suppress the inter-terminal voltage of a battery for transferring power with the motor from becoming less than a lower limit voltage. SOLUTION: During motor traveling, a threshold Vref for a voltage is set as a threshold for starting an engine based on a vehicle speed V and a residual capacity SOC (step S160), and when an inter-terminal voltage Vb of the battery is less than a set threshold Vref for a voltage (step S170), the engine is motored and started (steps S200 to S230, S280 to S300). Thus, it is possible to suppress the inter-terminal voltage Vb of the battery from becoming less than a lower limit voltage for discharging the battery. Thus, it is possible to start the engine in a much more proper timing. COPYRIGHT: (C)2009,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To more properly control the operating state of an internal combustion engine, and to properly start the internal combustion engine by driving a first motor based on the rotational position of the output shaft of the internal combustion engine thereby suppressing torque pulsation occurring at the start of the internal combustion engine and by preventing the first motor from being driven based on the improper rotational position of the output shaft of the internal combustion engine. SOLUTION: In starting an engine 22 in normal operation, the crank angle of an engine 22 is calculated based on the angle of rotation of the motors MG1 and MG detected by rotational position detection sensors 43 and 44 , and damping torque for suppressing torque pulsation occurring due to the motoring of the engine 22 by the motor MG1 is set based on the calculated crank angle, and the motoring and start of the engine 22 is performed while considering the damping torque, and when abnormality occurs in a transmission 60, the motoring and start of the engine 22 is performed without considering the damping torque. Thus, it is possible to suppress torque pulsation occurring due to the motoring of the engine 22 in a normal operation, and to prevent the damping torque based on an improper crank angle from being considered when the abnormality occurs in the transmission 60. As a result, the engine 22 can be properly started. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suppress gear shift shock in shifting the change gear ratio while a braking force is output to a driving shaft by a motor via a transmission, and to complete the gear shift before stopping. SOLUTION: When gear shift of the transmission 60 is requested during output of the braking force from the motor MG 2, the braking torque from the motor MG 2 is replaced by brakes 89a and 89b of driving wheels 39a and 39b to provide a state where no torque is output from the motor MG 2, then the transmission 60 is shifted, and, after the shift, the braking torque replaced by the brakes 89a and 89b is replaced by the braking torque from the motor MG 2. The replacing rate of the braking torque is set to increase as the braking torque replaced based on the position of a shift lever 81 or the depressing state of a brake pedal 85 increases and as the vehicle acceleration increases in the speed reduction direction. Thus, shock occurring in the speed reduction can be suppressed, and the gear shift can be completed before stopping. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To prevent shock and movement of a vehicle following a compression check. SOLUTION: The vehicle is constituted by connecting a first motor, an engine, and a driving shaft to a sun gear of a planet gear, a carrier, and a ring gear, respectively, and a second motor is connected to the driving shaft via a transmission. When cranking of the engine is required for compression check, the engine is usually cranked by the first motor, and control is performed so that the torque outputted to the driving shaft side in response to this is canceled by the second motor (S200-S240). When the transmission cannot normally transmit the power from the second motor (S120, S130 and S180), the cranking of the engine is not performed (S190 and S240). Thus, shock and movement of the vehicle can be prevented caused in a case wherein the torque output to the driving shaft following the cranking of the engine cannot be canceled by the second motor.
