Abstract: PROBLEM TO BE SOLVED: To more accurately measure the travel resistance in running of an electric vehicle. SOLUTION: When coasting run for measuring the travel resistance is instructed, an inverter 26 to drive a motor 22 is shut down, and when vehicle speed is larger than given vehicle speed Vref, a system main relay 30 to perform electric connection and break between the inverter 26 and a battery 24 is switched off, and when the vehicle speed is under the given vehicle speed Vref, the system main relay 30 is kept ON. Hereby, the regenerative braking of the motor 22 is prevented regardless of vehicle speed, therefore it can be put in a complete nondrive state. Accordingly, the travel resistance can be measured more accurately by measuring the travel resistance in this nondrive state. COPYRIGHT: (C)2006,JPO&NCIPI

解决方案：当指示用于测量行驶阻力的滑行运行时，关闭驱动马达22的逆变器26，并且当车速大于给定车速Vref时，执行电连接的系统主继电器30 逆变器26和电池24之间的断路被切断，当车速低于给定车速Vref时，系统主继电器30保持接通。 因此，与车速无关地防止电动机22的再生制动，因此可以将其置于完全非驱动状态。 因此，可以通过在该非驱动状态下测量行驶阻力来更精确地测量行驶阻力。 版权所有（C）2006，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To more appropriately display power used for driving a vehicle to a driver, as to a power meter that displays power used for driving the vehicle in the vicinity of a driver seat.
SOLUTION: As larger power is used for driving, a turning angle per unit power (unit turning angle) dθ of an indicator needle 64 is made smaller. An ecological driving zone 62b, in which power less than a prescribed value (such as 50 kW) is used, is displayed large as compared with a power meter in which the unit turning angle dθ is evenly displayed over the whole power, the prescribed power assumed as an upper limit value of power allowing the vehicle mounted with the power meter 60 to drive at a satisfactory fuel cost. This allows the power to be appropriately displayed to the driver.

Abstract: PROBLEM TO BE SOLVED: To improve a regulation object component exhausted when warming up a catalyst device, in a control device of a vehicle traveling in response to a traveling mode selected from a plurality of traveling modes. SOLUTION: This control device 60 prohibits travel by a power mode being one of the plurality of traveling modes (S140), when the catalyst device 52 determines as warming-up (YES in S100). Thus, since exhaust gas from an engine 12 does not increase, the regulation object component exhausted without being sufficiently treated by a catalyst of the catalyst device 52, can be improved.

Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of fuel consumption in a vehicle traveling by using power from an engine and power output from a motor through a transmission. SOLUTION: When down shift of a transmission is instructed under establishment of learning conditions of an idling controlled variable (S120, S130, S290, S320), the down shift of the transmission is performed during an idling operation of the engine regardless of the establishment of the learning conditions (S240), and the intermittent operation of the engine is performed after completion of the down shift (S380-S400). Thereby, when the learning conditions are established by the idling operation of the engine in down-shifting, the deterioration of the fuel consumption can be suppressed in comparison to the case of continuing the idling operation of the engine until the completion of leaning.

Abstract: PROBLEM TO BE SOLVED: To move smoothly perform starting or traveling to reverse traveling direction, and to suppress a full discharge of a capacitor device such as a secondary battery even while traveling to the reverse traveling direction, in a vehicle having an internal combustion engine and an electric power/motive power input/output device outputting at least a part of motive power outputted from the internal combustion engine accompanied by input/output of electric power and the motive power to an axle side as driving force advancing the vehicle. SOLUTION: When traveling an ascent gradient to the reverse traveling direction, driving of an auxiliary machine is stopped, and a charge/discharge requirement electric power Pb* is set such that it becomes a small charging electric power as the ascent gradient θ is enlarged (S150). When starting, a value zero is set to the charge/discharge requirement electric power Pb* within a range wherein the battery is not fully discharged (S180). Thereby, a torque acting to forward traveling direction outputted from an engine side so as to charge the battery is made to be small, and a torque acting to the reverse traveling direction is made to be large to allow the smooth starting or traveling in the ascent gradient in the reverse traveling direction.

Abstract: PROBLEM TO BE SOLVED: To allow a driver to have a gear shift feeling when a shift position SP is changed in an automobile capable of operating an engine at an arbitrary operation point regardless of the shift position SP by connecting the engine, a first motor, and an axle to a planetary gear mechanism and connecting a second motor to the axle. SOLUTION: When upshifting is performed in the shift position SP in a state where the shift position SP is within a sequential shift range, the rotation number Ne of the engine is temporarily reduced, so that the driver has the gear shift feeling. Consequently, an unnatural feeling is prevented from being given to the driver who is familiar to the gear shift feeling of the automobile with an automatic stage change gear mounted thereon.
