Abstract: PROBLEM TO BE SOLVED: To satisfy both of power performance and energy-saving, in an engine start during travel of HEV.SOLUTION: A hybrid vehicle can travel by either of electric travel using only output of a second power generating electric motor MG2 and hybrid travel using output of the second power generating electric motor MG2 and an internal combustion engine 20. After a battery 64 is externally charged by use of a charger 102, the vehicle performs electric travel in an EV mode. At that time, if vehicle required power becomes an engine start power threshold or more and if vehicle speed becomes an engine start vehicle speed threshold or more, the vehicle is shifted to a hybrid travel state. If the battery 64 is externally charged and thereafter the electric travel in the EV mode continues, the engine start vehicle speed threshold is set to a high side threshold. After the internal combustion engine 20 is started at least once during electric travel in the EV mode after external charging, the engine start vehicle speed threshold is set to a low side threshold lower than a high side threshold.

Abstract: PROBLEM TO BE SOLVED: To reduce unnecessary energy consumption and to prevent abrupt start of a vehicle in a brake hold control releasing time in the vehicle wherein brake hold control is released based on the degree of an acceleration demand by a driver. SOLUTION: An ECU carries out a program including steps S102, S112, S114, and S200. In the step S102, a control accelerator opening used for output control of driving force as the control degree of the acceleration demand by the driver is set to 0 when it is under the brake hold control (S100: YES). In the step S112, if an actual accelerator opening as the actual degree of the acceleration demand by the driver is higher than a predetermined opening A (0) (S106: YES), it is determined that the acceleration demand is given by the driver. In the step S114, a brake hold control releasing instruction is outputted. In the step S200, the control accelerator opening is gradually converged to the actual accelerator opening.

Abstract: 【課題】スリップ中にバッテリへの過大な電力の入力を防止しつつ必要な駆動力を出力する。【解決手段】トラクションコントロール(TRC)および姿勢保持制御(VSC)がいずれもオフとされており(S110)、且つ、駆動輪の空転によるスリップ中の場合(S130)、スリップ時の過充電抑制用の駆動力制限を解除すると共に(S160)、エンジン始動を禁止して(S170)、モータMG1とモータMG2とから駆動力を出力する両駆動モードにより走行可能とする。エンジン始動を禁止することにより、駆動輪のスリップが解消してグリップしたときに駆動輪の回転数が急速に低下しても、共線図よりモータMG1の回転数は値0に近付くだけであるからバッテリに過大な電力が入力されるのを防止することができる。また、過充電抑制用の駆動力制限の解除により、両駆動モードにおいて必要な駆動力を確保することができる。【選択図】図3

Abstract: PROBLEM TO BE SOLVED: To set a remaining capacity central value at which significant deterioration of fuel economy and emission can be avoided, even if a mode change-over switch is operated during travel in an EV mode.SOLUTION: A vehicle can travel in either of an EV mode for traveling using only output of a second power generating electric motor MG2, an HV mode for traveling with output of an internal combustion engine 20 added further and making remaining capacity of a battery 64 approach a remaining capacity central value using the output of the internal combustion engine 20, or an HVS mode. After the battery is externally charged, the vehicle travels in the EV mode. At that time, if an EV switch 96 is changed into an off state, the vehicle travels in the HVS mode. If cooling water temperature is lower than a water temperature threshold when starting travel in the HVS mode, an upper limit value of the remaining capacity central value is set to a first value (high side value), and thereafter, if the cooling water temperature becomes higher than the water temperature threshold, an upper limit value of the remaining capacity central value in the HVS mode is set to a second value lower than the first value until a ready-off state is assumed.
