摘要:
The invention concerns a device for controlling a hybrid power train of a motor vehicle comprising a heat engine and an electric engine powered by a battery that also supplies an onboard grid, the electric engine being able to operate as a generator in a regeneration phase during which a portion of the kinetic energy of the vehicle is transformed into recoverable electric power, characterised in that it comprises an estimation module (1.1) for estimating the electric power consumed by the onboard grid (PDCDC_Filtrée), an estimation module (1.3) for estimating the recoverable electric power (PDCDCMax_Absorb) depending on the running mode (E, U, EU, HW), a comparison module (1.4) for comparing the electric power consumed by the onboard grid and the recoverable electric power, and a limitation module (1.6) preventing the provision of electric torque to the wheels when the electric power consumed by the onboard grid is greater than the recoverable electric power.

摘要:
The invention relates to a method for starting an internal combustion of a hybrid vehicle comprising a first powertrain (1) which comprises an internal combustion engine (2), a first electric machine (3), and a transmission (5). The first electric machine (3) can be coupled to the internal combustion engine (2) via a disconnect clutch (7) and to a first and/or second drive axle (4; 204) via a starting element (6). The hybrid vehicle also comprises a second powertrain (201) with a second electric machine (203) to which the first and/or second drive axle (4; 204) can be coupled, wherein a respective drive torque can be provided via the first and second electric machine (3, 203). The invention is characterized by the following steps: operating the first electric machine (3) and actuating the starting element (6) after a first point in time (tv) such that a first electric machine (3) torque acting via the first powertrain (1) is reduced by a torque value (R) and operating the second electric machine (203) such that a second electric machine (203) torque acting via the second powertrain (201) is increased by a value (R) in a corresponding manner; and operating the first electric machine (3) and at least partly closing the disconnect clutch (7) after a second point in time (t0) such that the rotational speed of the internal combustion engine (2) is increased until a starting criterion is reached such that the internal combustion engine (2) supports a starting process.

An electronic control unit (16) of a hybrid vehicle (1) is configured to determine whether or not parking operation of the hybrid vehicle (1) is being performed. The electronic control unit (16) is configured to control the engine (10) and the rotary electric machine (MG1, MG2) such that starting the engine (10) when the parking operation of the hybrid vehicle (1) is being performed is harder than starting the engine (10) when the parking operation of the hybrid vehicle (1) is not being performed.

An electronic control unit (100) is configured to select one of a series mode, a series-parallel mode and a parallel mode as a running mode. A load level of a hybrid vehicle (1) is set to a value that is high in the order of a load level at which the parallel mode is selected, a load level at which the series-parallel mode is selected, and a load level at which the series mode is selected. That is, the electronic control unit (100) selects the series-parallel mode in an intermediate load region, selects the series mode in a low load region, and selects the parallel mode in a high load region.
摘要:
A device (DA) is intended to assist with the coupling/uncoupling of a first prime mover (MM1) to and from a drive train of a hybrid vehicle (V) further comprising a combustion engine (MT) and a second prime mover (MM2) that can be coupled to the combustion engine. The device (DA) is designed to compare a required torque with at least a first threshold s1 and a second threshold s2 when the combustion engine (MT) is in operation and a required torque is negative, and when the required torque drops below at least the first threshold s1, to order the coupling of the first prime mover (MM1), and when the required torque rises above at least the second threshold s2 to order the uncoupling of the first prime mover (MM1).
