METHOD FOR CONTROLLING DECELERATION OF A HYBRID VEHICLE AND HYBRID VEHICLE

摘要

The invention relates to a method for controlling deceleration of a hybrid vehicle comprising an internal combustion engine (12) and also at least one electromotor (14) and a deceleration fuel cut-off device which interrupts the supply of fuel of the internal combustion engine (12) when the vehicle is decelerated, and re-establishes the supply of fuel when a re-established rotational speed (n_mot,WE) of the internal combustion engine (12) is reached or exceeded. According to the invention, at least when the internal combustion engine (12) is at the operational temperature, the supply of fuel is re-established at a re-established rotational speed (n_mot,WE) of a maximum of 200 min^-1, in particular a maximum of 100 min^-1 above an idle speed (n_mot,LL) of the internal combustion engine (12). Preferably, the inventive re-established rotational speed (n_mot,WE) is located on the plane of the idle speed (n_mot,LL) or just above. The inventive re-established rotational speed (n_mot,WE) is significantly reduced in relation to common re-established rotational speeds and carries out an extension of the deceleration fuel cut-off phases and therefor reduces the consumption of fuel.
