摘要： A control system for a hybrid vehicle configured to reduce electricity consumption by a motor in a condition where a maximum output torque of an engine is restricted. A controller is configured to: calculate a current maximum torque of the engine when increasing a speed of the engine to achieve an acceleration demand; determine whether the current maximum torque of the engine is less than an inertia torque required to increase the speed of the engine; and adjust the reaction torque of the first motor to a value less than a predetermined value, if the current maximum torque of the engine is less than the inertia torque required to increase the speed of the engine.

摘要： A system for a vehicle includes a powertrain configured to propel the vehicle, and a controller configured to, during a first lap of the vehicle around a track, identify a portion of the track corresponding to a correlation of velocity, throttle position, and steering angle values indicative of a maximum power threshold, and, during a second lap, responsive to approaching the portion, limit power output by the powertrain causing temperature of the powertrain to fall and, upon entering the portion, increase power output to the maximum power threshold causing the temperature to rise, such that a difference in temperature between initiation of the limiting and exiting of the portion approaches zero.

摘要： A vehicle control device that controls a vehicle is configured to execute rotation speed control when the vehicle is in series traveling, in which a rotation speed of the internal combustion engine is increased to a first rotation speed in accordance with an increase in a speed of the vehicle, and when the rotation speed of the internal combustion engine reaches the first rotation speed, the rotation speed of the internal combustion engine is decreased to a second rotation speed lower than the first rotation speed; and restrict execution of the rotation speed control when receiving a predetermined operation.

摘要： A method for operating a drive unit for a motor vehicle. The drive unit has at least one internal combustion engine, an electric machine which is or may be drivingly coupled to the internal combustion engine, and a start-up clutch, via which the internal combustion engine and the electric machine are drivingly connected to an output shaft of the drive unit. In a start-up operation mode of the drive unit, the internal combustion engine is operated without ignition when the start-up clutch is open, and is cranked by the electric machine to a start-up speed, which is greater than an idle speed of the internal combustion engine. The internal combustion engine is ignition-operated and the start-up clutch is closed upon reaching the start-up speed. The invention further relates to a drive unit for a motor vehicle.

摘要： Methods and systems are provided for operating a hybrid vehicle during launch conditions from rest. In one example, a threshold speed below which a clutch is closed during a vehicle launch is adjusted so that driver demand wheel torque is held constant for a constant accelerator pedal position until the clutch is closed.

摘要： A method of controlling a split inflow of condensate water in a hybrid engine includes: determining whether condensate water is generated from an exhaust gas recirculation (EGR) device of a hybrid electric vehicle (HEV); determining an amount of the condensate water introduced into an hybrid engine; determining whether a vehicle speed of the HEV is within a predetermined speed range; determining whether a request torque of the HEV is within a predetermined torque range; determining whether a duration time of the vehicle speed within the predetermined speed range, and a duration time of the request torque within the predetermined torque range are greater than or equal to a predetermined duration time, respectively; and when the determined duration times are greater than or equal to the predetermined duration time, increasing an engine torque of the HEV.

摘要： Systems and methods for operating a driveline of a hybrid vehicle are described. In one example, vehicle launch is controlled according to a linear quadratic regulator that provides feedback control according to torque converter slip error and vehicle speed error. The vehicle launch is also controlled according to feed forward control that is based on requested torque converter slip and requested vehicle speed.

摘要： A powertrain system includes a control device configured, where an engine speed at the time of detection of an acceleration request with a high acceleration request index value is lower than a specific engine speed, to: set the specific engine speed as an initial target engine speed for an acceleration associated with the acceleration request; and in a first acceleration time period before reaching the initial target engine speed, control an internal combustion engine in accordance with a first target engine power based on the initial target engine speed and supply, to an electric motor, a battery power corresponding to a difference obtained by subtracting the first target engine power from a required vehicle power. The specific engine speed is a value predetermined as a lower limit value of an engine speed range in which engine sound of the internal combustion engine is heard inside the vehicle.

摘要： A variable speed hybrid electric supercharger assembly is controlled to regulate an adaptive state of charge of an energy storage device and/or to boost an engine based on a performance mode selected by a driver. In one example, a reference state of charge is determined based upon driving characteristics of a vehicle and compared to an actual state of charge of the energy storage device. If the difference indicates a deficit, an operation mode is selected to regenerate the energy storage device. In another example, a planetary gearing arrangement between an engine and an electric motor is configured to increase or decrease power transferred to the supercharger by the engine based upon the performance mode selected by the driver.

摘要： Methods and systems are provided for operating a hybrid vehicle during launch conditions from rest. In one example, a driver demand torque is held constant until a threshold vehicle speed is reached when a constant accelerator pedal position is present so that closing of a transmission input clutch may result in reduced driveline torque disturbances while a desired driver demand torque is delivered.
