Embodiment Construction

[0020] The invention particularly relates to hybrid electric vehicles. The vehicle is preferably, but not necessarily, an external grid chargeable vehicle. The present invention proposes a control method for a first motor suitable for charging a high-power storage battery dedicated to power supply for a second motor for traction. The control method is used to limit the acoustic and vibration hazards of the drivetrain, in particular to reduce the charge if the driver's set point is increased. However, the method ensures a minimum charge level of the accumulator to power the electric traction of the vehicle, advantageously controlled according to the driver's settings, so as not to hinder the driver.

[0021] First, a drivetrain architecture suitable for implementing the control method according to the invention is described. figure 1 with Figure 1b An example of a schematic diagram of such a powertrain is shown. exist figure 1 Among them, the hybrid power transmission ass...

Abstract

The invention relates to a method for controlling an electrical machine (13) of a hybrid powertrain (1) for recharging an electrical power battery (17) of an electric traction. The control method is configured such that the electrical machine (13) takes up a drawing torque from the heat engine (11), which torque has an upper limit, and from which the set value selected by the driver to respect anacoustic stress level is derived. According to the invention, when the set value selected by the driver is higher than a torque threshold, the method limits the drawing torque to a lower limit to ensure that the battery (17) of the electric traction is recharged.

Description

technical field [0001] The field of the invention relates to methods for controlling an electric machine of a hybrid powertrain according to driver settings to comply with acoustical constraints and to guarantee the charge level of the battery. Background technique [0002] A large number of architectures exist for the powertrain of a hybrid vehicle. One architecture includes a traction heat engine coupled to the front axle, a traction electric motor powered by a high-power battery and coupled to the rear or front axle and adapted to extract torque from the engine torque to charge the battery electric machine, wherein the engine torque is provided by a heat engine for traction. For the purpose of driving comfort, research is ongoing to reduce the acoustic and vibration noise generated by the power train and mainly emitted by the heat engine. However, charging the battery during driving increases the load on the heat engine and thus increases noise and vibration. [0003] ...
