Abstract: In a hybrid vehicle 20, when the ECO switch 88 is turned on, an intermittent permissive ceiling speed Vref for permitting an intermittent operation of an engine 22 is set to a second vehicle speed more than a first vehicle speed used on a turn-off condition of the ECO switch 88 (S130). The engine 22 and a motor MG2 are controlled so that a driving power equivalent to a torque demand Tr* is ensured with the intermittent operation of the engine 22 when a vehicle speed V is not more than the intermittent permissive ceiling speed Vref (S250,S270,S200-S230).

Abstract: In a hybrid vehicle 20, when an ECO switch 88 is turned off while an intermittent operation of an engine 22 is prohibited in response to a warm-up demand of the engine 22 according to a cooling water temperature Tw or a heating demand, the engine 22 is autonomously operated at a target rotational speed Ne* derived and set from a normal autonomous rotational speed setting map (Steps 170, S190). When the ECO switch 88 is turned on while the warm-up is demanded, the engine 22 is autonomously operated at the target rotational speed Ne* set based on an ECO mode autonomous rotational speed setting map so as to be not more than the value derived from the normal autonomous rotational speed setting map (Steps 180, S190).

Abstract: In a hybrid vehicle 20, an engine 22, motors MG1 and MG2 are controlled so that vibration due to torque ripple arising in a crank shaft 26 is reduced by torque for a vibration control from the motor MG1 and torque demand Tr* is output to a ring gear shaft 32a when an ECO switch 88 is turned off during a start of an engine 22. When the ECO switch 88 is turned on during the start of an engine 22, the engine 22, motors MG1 and MG2 are controlled so that the torque for a vibration control from the motor MG1 becomes value “0” and the torque demand Tr* is output to the ring gear shaft 32a.

Abstract: In a hybrid vehicle 20, an engine 22, motors MG1 and MG2 are controlled so that the engine 22 is operated at a target operation point set at Step 120 based on a torque demand Tr* and the motor MG2 outputs lower power for driving in comparison with a turn-off condition of an ECO switch 88 when the ECO switch 88 is turned on upon driving with power from both the engine 22 and the motor MG2 (Steps S130-S150 and S170-S200).

Abstract: In a hybrid vehicle 20, when the ECO switch 88 is turned on, Step S140 determines whether or not a driving state is an economy driving state based on an ECO mode driving state determination map having a tendency not to regard the driving state as the economy driving state in comparison with a normal driving state determination map. A determination result of Step S140 is displayed on a meter display unit 90 in the form of an illumination or an extinction of an ECO mark 95 so as to inform the driving state is the economy driving state or not (Step S180).

Abstract: When determined that a driver's accelerator operation is rough during the turn-on condition of an ECO switch 88 while a hybrid vehicle 20 is driven without an operation of an engine 22 (Step S120), a threshold value Pref with respect to a power demand P* is set to a value P2 that is larger than a value P1 of the turn-off condition of the ECO switch 88 so as to give priority to fuel consumption of the engine 22 (Step S140). Then, the engine 22, motors MG1 and MG2 are controlled with a start of the engine 22 as necessary so as to ensure torque equivalent to a torque demand Tr* (Steps S150-S230).

Abstract: In an eccentric radial piston pump, a rib 12 protruded in a radial direction is formed on an inner peripheral surface of an end portion on a discharge side of an eccentric cam ring 3 over a prescribed range. In an eccentric radial piston motor, a rib 12 protruded in a radial direction is formed on an inner peripheral surface of an end portion on a high pressure side of an eccentric cam ring 3 over a prescribed range. By the rib 12 formed in the radial direction, a rigidity of the eccentric cam ring 3 can be improved, and the eccentric cam ring can be prevented from being deformed by a thrust from the piston. Thus, the rigidity of the eccentric cam ring can be increased without increasing the thickness of the eccentric cam ring, and further the eccentric radial piston pump and the eccentric radial piston motor in which outside dimensions in the radial direction are reduced can be provided.

Abstract: During the period of deceleration of a vehicle, an air conditioning control unit modifies a target cooling temperature (TEO) of an evaporator to a temperature lower than that before the deceleration by ? ° C. in order to store cold in the evaporator (step S130). When the vehicle comes to rest, the air conditioning control unit sets an upwardly-modified target temperature TEOK, which is a temperature modified toward more or less higher temperatures from the target cooling temperature TEO, and brings a compressor to rest and keeps the resting state of the compressor until a detected temperature TE of an evaporator discharge temperature sensor exceeds TEOK (step S180). Therefore, it is possible to effectively utilize the cold heat stored in the evaporator 6 during the period of deceleration of the vehicle with a good feeling of passengers being maintained while the vehicle is at rest.

Abstract: In a vehicle air conditioner having a variable displacement compressor, a control unit calculates a target cooling temperature of air to be cooled by an evaporator, and controls a discharge capacity of the compressor such that a detected air temperature of the evaporator approaches the target cooling temperature. When a deceleration running state of the vehicle is detected, the control unit sets a corrected target cooling temperature lower than the target cooling temperature by a predetermined temperature, and controls the discharge capacity of the compressor such that the detected air temperature approaches the corrected target cooling temperature when the detected air temperature is lower than the corrected target cooling temperature, or controls the discharge capacity of the compressor approximately at the maximum capacity regardless of the corrected target cooling temperature when the detected air temperature is not lower than the corrected target cooling temperature.

Abstract: An object of the present invention is to provide a method for manufacturing electrodes that can effectively suppress edge-curl when metal electrodes such as bus electrodes and data electrodes are patterned mainly by a photolithography method. In order to achieve the above object, in the manufacturing method in the present invention, an amount of undercut generated by difference in a degree of dissolution caused by developing solution is controlled, and baking is performed at a temperature such that glass in a protrusion formed at side edges becomes soft so as to touch a substrate by gravity. With such method for manufacturing, it becomes possible to make the side edges rounded whose curvature changes continuously.
