20130079969 | CONTROL DEVICE FOR HYBRID VEHICLE, CONTROL METHOD FOR HYBRID VEHICLE, AND HYBRID VEHICLE - First output power is set in accordance with operation by a driver. In addition, second output power greater than the first output power is set. A hybrid vehicle is controlled so that an engine is driven in accordance with the second output power. The hybrid vehicle is controlled so that the engine is stopped when the first output power is equal to or smaller than an engine stop threshold value. | 03-28-2013 |
20130218390 | ELECTRIC POWERED VEHICLE AND CONTROL METHOD THEREOF - When a determination is made that the shift range is other than the R range, an ECU sets the system voltage for forward running. When a determination is made that the shift range is in the R range, the ECU sets the system voltage for backward running. The system voltage for backward running is set to become higher than the system voltage applied for forward running for an identical level of acceleration requirement for the vehicle. | 08-22-2013 |
20130297193 | HYBRID VEHICLE AND METHOD FOR CONTROLLING THE SAME - A motor generator and a power converter are driven by an engine, to supply electric power to a power storage device. ECU causes the engine to start if SOC of the power storage device falls below a first threshold value, and causes the engine to stop if SOC exceeds a second threshold value which is larger than the first threshold value. During a vehicle stop, if SOC exceeds a third threshold value which is larger than the first threshold value and smaller than the second threshold value, ECU causes the engine to stop. | 11-07-2013 |
20130317682 | HYBRID VEHICLE AND CONTROL METHOD THEREOF - When a determination is made that the running mode is an HV running mode at S | 11-28-2013 |
20140039744 | HYBRID VEHICLE AND METHOD FOR CONTROLLING THE SAME - A motor generator and a power converter are driven by an engine, to supply electric power to a power storage device. ECU causes the engine to start if SOC of the power storage device falls below a first threshold value, and causes the engine to stop if SOC exceeds a second threshold value which is larger than the first threshold value. In the case where a running range has been selected when the vehicle stops, ECU causes the engine to stop if SOC exceeds a third threshold value which is larger than the first threshold value and smaller than the second threshold value. In the case where a non-running range has been selected, ECU causes the engine to stop if SOC exceeds the second threshold value. | 02-06-2014 |
20140107878 | VEHICLE - An ECU is mounted on a vehicle including an engine and a motor that can generate cranking torque applied to a rotation shaft of the engine. Where a request for starting the engine is not issued, the ECU determines whether the engine is during coasting or not. The ECU changes cranking target torque in accordance with engine rotation speed. In this way, engine rotation speed during cranking can be reduced to and remain in the optimum region where misfire and resonance can be avoided. | 04-17-2014 |
20140139150 | VEHICLE DRIVING DEVICE - A vehicle driving device includes a high-voltage battery, a voltage converter capable of converting a voltage of the high-voltage battery to a voltage ranging from the voltage of the high-voltage battery to a predetermined upper limit voltage, an inverter supplied with a power-supply voltage from the voltage converter, a driving motor driven by the inverter, and a control device for controlling the voltage converter and the inverter. The control device determines whether or not to limit an upper limit voltage of the voltage converter smaller than the predetermined upper limit voltage on the basis of a usage environment or usage load of a vehicle. In the case where the upper limit voltage of the voltage converter is limited smaller than the predetermined upper limit voltage, the control device drives the inverter after limiting a request torque on the basis of an accelerator pedal operation performed by a driver. | 05-22-2014 |
20140196445 | HYBRID VEHICLE CONTROL DEVICE AND HYBRID VEHICLE - In controlling a hybrid vehicle, an internal combustion engine and an electric motor are controlled such that, when a power request is received while traveling with an operation of the internal combustion engine stopped and a requested power required for traveling is higher than a predetermined power, the operation of the internal combustion engine is started with an intake air volume based on the requested power and the hybrid vehicle travels with the requested power. When the power request is received for the first time after ignition-on, the start control for controlling the internal combustion engine is performed such that the operation of the internal combustion engine is started with an intake air volume lower than that based on the requested power. The hybrid vehicle includes a controller that performs the above control, an internal combustion engine, an electric motor, a battery, and a purification device. | 07-17-2014 |
20140210261 | VEHICLE, AND CONTROL METHOD AND CONTROL DEVICE FOR VEHICLE - A vehicle includes a traveling battery storing electric power, an auxiliary battery connected to the traveling battery, a DC/DC converter supplying the electric power from the traveling battery to the auxiliary battery, and an engine operated at a load corresponding to the electric power supplied from the traveling battery to the auxiliary battery. If the load of the engine is smaller than a threshold value during load operation of the engine, the DC/DC converter supplies the electric power from the traveling battery to the auxiliary battery. | 07-31-2014 |
