Abstract
Various embodiments include a control system for the regeneration of a particle filter in an exhaust gas flow of an internal combustion engine of a hybrid vehicle including an electric machine comprising: a particle filter; a temperature sensor measuring an actual temperature of the filter; a first heat source upstream of the filter; and a controller. The controller is programmed to: determine a temperature difference between a setpoint temperature for regeneration of the particle filter and the actual temperature of the particle filter; calculate a power output difference to be applied based at least in part on the temperature difference; and control the first heat source using the power output difference.
