摘要:
A method for a hybrid vehicle for limiting the torque drawn by a first electric machine (12) linked to a combustion engine (2) linked to a transmission (4), said first machine being designed to supply current to a battery (10) of the onboard network of the vehicle, and an energy storage device (16) which delivers said energy to a second traction electric machine (20), the vehicle comprising an automatic system for controlling the speed of same, characterised in that, in case the combustion engine (2) is not able, on a given ratio of the transmission (4), in response to a request from the automatic speed control system, to deliver the preferred acceleration, it sheds the load of the energy storage device (16) or of the battery (10) of the onboard network before using the second electric machine, or changing the ratio, if this load shedding alone is not sufficient to provide the preferred acceleration.
摘要:
A method for limiting the torque drawn by a first electric machine (12) coupled to a traction combustion engine (2) of a hybrid vehicle, said vehicle comprising a second traction electric machine (20) powered by an electrical energy storage device (16), said first machine, designed to supply current to the onboard network (18) of the vehicle, also being able to charge the energy storage device (16), characterised in that, in case of a high torque request made by the driver and exceeding the capabilities of the combustion engine (2), it limits the torque absorbed by the first machine by adjusting the electrical power delivered for said charging, in order to meet said torque request.
摘要:
A method for monitoring the electric energy supplied by batteries (4) for the propulsion of a hybrid vehicle, wherein the estimated remaining distance of a journey and the available charge of said batteries are taken into account in order to calculate a desired discharge coefficient of said batteries, which is transmitted to a distribution function of the torque setting (18) between the electric motorization (28) and a propulsion heat engine (24), characterized in that it makes an assessment periodically along the journey, according to the real discharge coefficient of the last period, the remaining distance of the journey and the available charge, in order to calculate in each instance a new target discharge coefficient making it possible, while remaining consistent, to reach the end of the journey with a final minimum charge.
