Abstract: PROBLEM TO BE SOLVED: To suppress the over-charge of an electric storage device when the operation of an internal-combustion engine is stopped during the output of braking force to a driving shaft. SOLUTION: When the stop of the operation of the engine 22 by a motor MG1 is indicated during the output of the braking force (a negative torque) to a ring gear shaft 32a being the driving shaft from a motor MG2, the fuel of the engine 22 is cut. Then the motor MG1 is controlled to output the negative torque in order to stop the operation of the engine 22. The motor MG2 is also controlled so as to limit the negative torque to be outputted from the motor MG2, based on the electricity generation power of the motor MG1 and the input limit of a battery 50 in this case. The torque shortage due to the torque limit to the motor MG2 is outputted from braking devices 89a, 89b attached to driving wheels 63a, 63b. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To enable a vehicle to travel by outputting more appropriate torque, without charging an electricity accumulating device, such as a battery with excessive power, when starting or low-speed traveling on an uphill. SOLUTION: When a driver requests large torque at the starting or low-speed traveling on a slope with an ascending incline (S120), the lower limit number of revolutions Nmin and upper limit number of revolutions Nmax of an engine are calculated from a request power Pe*, within the range of the input limit Win of a battery or the status of a vehicle (S150 to S170), and the target number of revolutions Ne* of the engine is set as the number of revolutions for dividing the lower limit number of revolutions Nmin and the upper limit number of revolutions Nmax with inclination coefficients k, which are inclined to become smaller, according to as an inclination θ becomes larger (S190); and target torque Te* or torque commands Tm1* and Tm2* of motors MG1 and MG2 are set and controlled by using the target number of revolutions Ne* (S200 to S250). Thus, a vehicle can travel by outputting more appropriate torque. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suppress battery depletion in a secondary battery by regulating the voltage of a secondary battery system according to the state of the secondary battery.
SOLUTION: A left standing time T equivalent to the time from the ignition-off to the ignition-on of a vehicle and an accessory power Ph consumed by accessories being driven are inputted (S100). When the accessory power Ph is lower than a threshold value Pref, a higher voltage is set as regulated voltage Vs with increase in left standing time T (S130). Regulation is carried out by a DC-DC converter so that the voltage of a low-voltage system with which an accessory battery is connected becomes equal to the set regulated voltage Vs (S140). Thus, shortage of battery power in the accessory battery can be suppressed. When the accessory power Ph is equal to or higher than the threshold valve Pref, a regulated voltage Vs is set based on the accessory power Ph (S120). Thus, the voltage of the low-voltage system can be regulated to a more appropriate voltage.

Abstract: PROBLEM TO BE SOLVED: To output request torque required by a vehicle and to suppress a rise in the temperature of an inverter. SOLUTION: When the temperature of an inverter 24 exceeds the threshold value as a temperature allowing the inverter 24 to operate normally, the torque output by a motor M1 is gradually reduced to restrict the output from the motor M1 and to output torque from the motor M2 so as to output the demand torque. The same process is performed when the temperature of an inverter 25 exceeds the threshold value. As a result, the demand torque can be output even when either temperature of inverter 24 or 25 exceeds the threshold value, enabling a sense of incompatibility to a driver to be suppressed. Furthermore, a rise in the temperature of the inverters 24, 25 can be suppressed. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To measure a travelling resistance of a hybrid vehicle more accurately. SOLUTION: In response to a coasting drive instruction for measurement of a travelling resistance of the hybrid vehicle, a change of a gear position in a transmission 60 is prohibited and both an engine 22 and a motor MG1 are stopped. A canceling torque is calculated, which cancels out a torque applied to a ring gear shaft 32a or a drive shaft via a power distribution integration mechanism 30 by generation of an inertia torque due to a change in the number of rotation of the motor MG1. The calculated canceling torque is set to a torque command Tm2* of a motor MG2, and the motor MG2 is driven and controlled with the torque command Tm2*. This arrangement makes the ring gear shaft 32a as a drive shaft completely free and enables accurate measurement of the travelling resistance of the hybrid vehicle during such a coasting drive of the hybrid vehicle in a fully non-driving state.
