An HV-ECU performs processing including calculating requested system power, calculating requested engine power when an engine activation request has been issued, setting an operating point on a predetermined operating line, setting an upper limit value of magnitude of an amount of lowering in engine rotation speed to a first value when a vehicle is in a sport running state and when the previous operating point is within a forced induction range, setting the upper limit value to a second value when the vehicle is not in the sport running state or when the previous operating point is not within the forced induction range, correcting the operating point, and outputting an engine operation state command, a first MG torque command, and a second MG torque command.

An HV-ECU performs processing including calculating requested system power, calculating requested engine power when an engine activation request has been issued, obtaining a turbo temperature, setting an operating point on a predetermined operating line when the turbo temperature is equal to or lower than a threshold value Ta, setting as the operating point, a position on a higher rotation speed side by a predetermined value along an equal power line when the turbo temperature is higher than the threshold value Ta, carrying out engine control, and carrying out MG control.

A hybrid system includes a transmission control module, a power source, a transmission, and a drive train. The transmission control module partially operates the hybrid system and receives operating information from various components of the system, calculates power losses in the drive train, and calculates the driving torque needed to reach a target power profile determined from a driver's input.

An apparatus, system, and method for controlling functions of a vehicular alarm. The method includes receiving one or more signals including location information, determining a location of the vehicle using the location information, setting one or more functions based on the location information, determining whether an alarm function is activated, and activating the one or more functions according to the setting upon determining that an alarm has been activated. The method may further include using GPS data or signals transmitted from one or more base stations (e.g., from cellular telephone base stations, computer networks, proprietary transmitters, etc.) to determine the position of the apparatus (e.g., installed in the vehicle). The apparatus may also inform a user of regulations relating to an area dependent upon its location.

Systems and methods for operating a vehicle that includes an engine that may be automatically stopped and started are described. In one example, a requested driver demand power may be filtered via a first order low pass filter in response to a powertrain speed. The filtered requested driver demand power may be a basis for automatically stopping and starting an engine.

A control system for hybrid vehicles to prevent a reduction in a drive force when an output power of a battery is restricted. A first motor translates an output power of the engine partially into an electric power. A transmission mechanism distributes an output torque of the engine to the first rotary machine side and an output member side. A second motor is operated by one of the electric power translated by the first rotary machine and an electric power accumulated in the battery to generate a power. An operating mode can be selected from a first mode in which the output torque of the engine is delivered to the output member side at a first ratio, and a second mode in which the output torque of the engine is delivered to the output member side at a second ratio. The second ratio is smaller than the first ratio. A controller is configured to restrict selection of the first mode when an available output power of the battery to be supplied to the second rotary machine is smaller than a predetermined value.

A method for operating a drive-train (1) of a vehicle, in particular a municipal or agricultural utility vehicle, which has at least one drive machine (2), a vehicle transmission (3) with at least two gears, at least one driven axle (8) and at least one power take-off (10). A normal power level is supplied by the drive machine (2), which is controlled or regulated in accordance with a normal torque characteristic curve (18). An operating-situation-dependent manner additional power can be supplied to the at least one driven axle (8) and/or to the at least one power take-off (10). The additional power supplied is controlled or regulated in accordance with operating-situation-dependent torque characteristic curves (18, 19a to 19d, 20a to 20d) which are called up as a function of the gear selected at the time.

A drive force control system configured to reduce a total energy consumption of a hybrid vehicle. The drive force control system calculates: an output power of the engine which can optimize a thermal efficiency given that the engine is operated at a best fuel point; and a required electric power to be supplied from a battery or to be generated by a control motor, which can adjust the drive power established by the output power of the engine to the required power. A power exchange between the control motor and the battery is interrupted if the required electric power to be supplied from the electric storage device or to be generated by the control motor is less than a first predetermined electric power.

A hybrid electric vehicle includes an intelligent vehicle controller, an electric motor, a battery, an internal combustion engine (ICE), and an electrical generator coupled to the ICE configured to provide electricity to the battery and the electric motor. The intelligent vehicle controller receives ICE power level shifting data from the electrical generator, ICE, battery, and electric motor. The intelligent vehicle controller determines a desirable torque and/or a desirable revolutions per minute (RPM) for the ICE based on the received ICE power level shifting data by utilizing an efficiency map that includes fuel efficiency contours and noise, vibration, and/or harshness (NVH) level lines for the hybrid electric vehicle. The intelligent vehicle controller may have first and second vehicle operation modes, and may derive first and a second desirable power levels for the ICE in the first and second operation modes, based on the ICE power level shifting data.

A method of controlling vehicle stopping is provided. The method includes dividing an open space from a closed space, in which a gate is connected to the ground, to apply an open space stop control mode to the open space and to apply a closed space stop control mode to the closed space. Additionally, spatial division stop control is performed in which a control condition for each of an engine power, a vehicle interior temperature, and a battery state of charge (SOC) is varied between the open space stop control mode and the closed space stop control mode when a vehicle enters the closed space.
