Embodiment Construction

[0054] It should again be noted that the invention is described here using the example of an electric hybrid vehicle, however, the electric machine can be replaced by, for example, pneumatic or hydraulic technology, preferably hydraulic technology.

[0055] Furthermore, it should be noted that the invention is not intended to modify the catalytic converters or particulate filters normally used in hybrid vehicles or even conventional vehicles. Furthermore, the invention does not provide for any modifications, additions or deletions at the structural or architectural level of the vehicle, more particularly in the exhaust line.

[0056] figure 1 A motor vehicle is shown that may be used to describe the invention, including, for example, the following equipment and components.

[0057] The figure shows a hybrid vehicle comprising a heat engine 2 driven by an automatically controlled clutch 4 and a transmission 6 with different gear ratios connected to the front drive wheels 8 of ...

Abstract

The invention relates to a system for controlling the temperature of a catalyst of an exhaust line of a hybrid vehicle. The system comprises a catalyst having a light-off temperature from which the catalyst is in an active mode in which the treatment is carried out. The temperature of the catalyst is controlled according to a request for instantaneous engine power by the driver and a demand on theother power source, such that it is always at least equal to the light-off temperature, and when a particle filling level threshold of the particle filter is determined as having been reached, the heat engine is controlled such that the particle filter reaches the regeneration temperature in order to be regenerated. The invention also relates to an identical method, and to a hybrid motor vehiclecomprising the system.

Description

technical field [0001] The invention relates to a system for controlling the temperature of a catalytic converter and a particulate filter of an exhaust line of a hybrid vehicle. More specifically, the invention aims to propose a solution for optimally managing the temperature of such catalytic converters and particulate filters equipped to the vehicle, which are currently placed in the exhaust of the vehicle's heat engine. In the exhaust line of combustion gases. Background technique [0002] In the following, the invention is described in connection with one of this applications, more precisely with respect to an electric hybrid motor vehicle, ie a motor vehicle comprising a heat engine and at least one electric motor associated to an energy storage device. [0003] It should be noted, however, that the invention is not limited to the use of electric machines in hybrid vehicles, which may for example comprise a drive train comprising at least one heat engine and at least ...
