Embodiment Construction

[0104] already described Figure 1-3 Different traction chain configurations for hybrid vehicles in which any of the above-mentioned aspects of the invention can be implemented.

[0105] exist Figure 1-3 In the embodiment, a traction chain 1 of a hybrid vehicle includes two driving wheels 2 , an electric motor 3 and an internal combustion engine 4 . However, the present invention is not limited to a specific number of capstans. The motor 3 is, for example, a permanent magnet synchronous motor. In the described embodiment, I1 denotes a rated power of the order of 8 kW.

[0106] In these embodiments, the internal combustion engine 4 is regarded as a gasoline, diesel or biohydrocarbon fueled internal combustion engine.

[0107] with in Figure 1-3 Identical to the system described in , the traction chain 1 includes an electrical energy storage device 5 that supplies power to an electric motor 3 via an inverter 6 . The electrical energy storage device 5 is formed, in particula...

Abstract

Method for starting a hybrid vehicle comprising: an electric motor (3), an internal combustion engine (4), and a clutch system (7) selectively coupling at least the electric motor (3) to drive wheels (2) of the vehicle , the method comprising a plurality of steps (20, 21, 22), wherein: (i) starting (20) the electric motor (3), (ii) regulating (21) the speed of the electric motor (3) around at least a certain value, and (iii) clutching A system (7) for coupling (22) said drive wheels (2) and an electric motor (3) of a vehicle so that the electric motor (3) propels the vehicle.

Description

technical field [0001] The invention relates to starting a hybrid vehicle comprising an electric motor and an internal combustion engine, in particular a gasoline or diesel internal combustion engine. Background technique [0002] According to the invention, the hybrid vehicle starts when the torque is capable of moving the vehicle, which is also known to those skilled in the art by the term "launching" of the vehicle. [0003] There are four phases before the start of a vehicle equipped only with an internal combustion engine: the phase during which the internal combustion engine is started; the low speed phase during which the speed of the internal combustion engine is regulated around a predetermined value which can be predetermined via the engine control unit; idling A phase, during which the internal combustion engine and gearbox are coupled by means of the clutch system of the vehicle's traction chain; and a phase, during which the internal combustion engine drives the...
