摘要： Provided is a power generation control device for a hybrid vehicle that prevents unintended engagement of a released engagement clutch during idle power generation. An internal combustion engine (ICE) is operated during idle power generation so that the input-output differential rotation speed of engagement clutches (second and third engagement clutches (C2, C3)) for connecting a power source (a first motor generator (MG1) and the internal combustion engine (ICE)) and the drive wheels becomes a value greater than or equal to a rotation difference threshold value at which the engagement clutches (the second and third engagement clutches (C2, C3)) are not engaged.

摘要： A hybrid electric vehicle has a first mode in which slippage of a clutch between an electric motor and a driving wheel is allowed and controlled by rotational speed control of the electric motor and a second mode in which the slippage of the clutch is allowed and controlled by rotational speed control of an engine. When the vehicle is stationary in the first mode, a controller reduces a control setpoint of hydraulic pressure of the clutch from an initial point. The controller identifies a reference point of the control setpoint with which actual output torque of the electric motor is substantially constant with respect to the reduction of the control setpoint. Then, the controller increases the control setpoint to a precharge point, and reduces the control setpoint to a corrected point that is lower than or substantially equal to the initial point and higher than the reference point.

摘要： In a method and system for automatic shift to a neutral gear of a motorized vehicle, the vehicle is provided with an automatic gear box controlled by a control unit. When automatically shifting to neutral gear,it is sensed that the foot brake pedal is actuated. It is also determined if the vehicle will remain in a stationary position with the neutral gear engaged. If it has been determined that the vehicle will remain in a stationary position with the neutral gear engaged,an automatic shift to neutral gear is enabled when the foot brake pedal is actuated.

摘要： A power transmission control device, which is applied to a hybrid-vehicle provided with an internal combustion engine (E/G) and a motor (M/G) as power sources, includes a manual transmission and a friction clutch. When the shift position is in "neutral", the friction clutch is in an engaged state, an accelerator opening is "0", and a battery remaining amount SOC is less than a threshold TH, a charge condition is satisfied. When the charge condition is satisfied, charge of a battery by using an E/G torque is carried out. Specifically, the M/G is driven, by using the E/G torque, as an electrical power generator, and electric energy acquired by electric power generation by the M/G is used to charge the battery. As a result, for the HV-MT vehicle, by using the internal-combustion-engine torque, the battery for supplying the electric motor with the electric energy can be efficiently charged.

摘要： In the case that an auxiliary such as the air conditioner is operated with electric power from the commercial power supply by controlling the charger prior to the system startup and the inter-terminal voltage Vb of the battery is more than or equal to the threshold value Vref that is a voltage where there is a possibility of overcharging the battery when the battery is charged, the supply voltage V* of the electric power supplied from the charger is set to the voltage V2 that is a little smaller than the threshold value Vref (S130), and the auxiliary is operated with the electric power from the battery and the electric power from the charger. This arrangement enables to prevent overcharging the battery and to operate the auxiliary in the case that an auxiliary such as the air conditioner is operated with electric power from the commercial power supply by controlling the charger prior to the system startup.
