摘要： A driving system, vehicle, and control method in which a difference between the detection value of an intake air pressure sensor and an atmospheric pressure sensor is computed as a detection value difference in the engine stop condition. An estimate of a potential for an abnormality of the detection value difference is determined, or the abnormality of the detection value difference is determined according to the duration time of an unusual state having the detection value difference of greater than a preset reference value. In an ignition-on state, when a delayed activation is requested, it is identified whether the abnormality in the detection value difference is to be determined. The delayed activation is requested in response to confirmation of a potential abnormality condition where there is a potential for an abnormality in the detection value difference but the abnormality in the detection value difference is not determined.

摘要： PROBLEM TO BE SOLVED: To reduce excessive discharge of a battery device while improving the energy efficiency of a vehicle. SOLUTION: When motor temperature Tm is less than a threshold Tref and vehicle speed V is less than a threshold Vref, a high voltage system is controlled to have a predetermined low voltage V1 or less through a booster circuit, and when the motor temperature Tm is less than the threshold Tref, and the vehicle speed V is the threshold Vref or more, the high voltage system is controlled to have an input maximum voltage Vset or less through the booster circuit. When the motor temperature Tm is the threshold Tref or more, the high voltage system is controlled to have the input maximum voltage Vset or less regardless of the vehicle speed V. Thereby the energy efficiency in a vehicle with good energy efficiency can be improved more by controlling the high voltage system at the predetermined low voltage V1 or less than by controlling it at the input maximum voltage Vset or less.

摘要： During an operation of an engine, an input limit Swin and an output limit Swout of a battery are set to a power demand-based input limit Wp*, which depends on a power demand P*, and to an accelerator opening-based output limit Wacc, which depends on an accelerator opening Acc (steps S400 to S420). This control technique effectively prevents the battery from being frequently charged or discharged to a relatively high level of electric power within an allowable electric power range defined by the reference input limit Bwin and the reference output limit Bwout, thus restraining premature deterioration of the battery.

摘要： When the driver heavily depresses an accelerator pedal to start a hybrid vehicle in an engine stop condition, the control of the invention waits until elapse of a preset wait time and then starts outputting a torque equivalent to a preset torque demand to a ring gear shaft or a driveshaft. The preset wait time is determined not to make the driver feel uncomfortable with a poor response. This arrangement desirably shortens a time period when the vehicle acceleration is restricted due to insufficient power output until the engine starts to output sufficient power and make significant contribution to the vehicle acceleration. The control of the invention thus desirably prevents the driver from feeling the unexpectedly slow acceleration.
摘要翻译：当驾驶员严重压下加速器踏板以在发动机停止状态下启动混合动力车辆时，本发明的控制等待直到经过预设的等待时间，然后开始向齿轮轴输出等于预设扭矩要求的转矩，或者一个驱动轴确定预设的等待时间不会使驾驶员对不良响应感到不舒服。这种布置理想地缩短了由于功率输出不足而限制车辆加速度直到发动机开始输出足够的动力并且对车辆加速度有显着贡献的时间段。因此，本发明的控制希望防止驾驶员感到意外的缓慢加速。

摘要： In requirement of catalyst degradation control with setting of a catalyst degradation control flag Fc to 1, the braking control of the invention sets torque commands Tm1* and Tm2* of two motors and controls the operations of an engine and the two motors to shift a drive point of the engine on an optimum fuel consumption operation curve by a preset rotation speed variation Nrt1 in a specific range of rotation speed that ensures no occurrence of a misfire in the engine within an input limit Win of a battery and to ensure output of a braking torque demand Tr* to a ring gear shaft or driveshaft (steps S200 to S250). Such braking control stably lowers a rotation speed Ne of the engine to a target rotation speed Ne* and desirably enhances the fuel consumption under the catalyst degradation control.
