Abstract:
1. A vehicle, comprising: an internal combustion engine operatively disposed within the vehicle, the engine to generate exhaust gases, the engine having a front end accessory drive (FEAD); an alternator operatively connected to the engine to be driven by the FEAD, the alternator producing DC power; an ultracapacitor operatively connected to the alternator to receive electrical energy therefrom; an exhaust gas treatment system operatively connected to the engine to receive exhaust gases therefrom, the exhaust gas treatment system including an electrically heated catalyst (EHC) device electrically connected to the ultracapacitor to selectively heat a catalytic exhaust system component wherein the ultracapacitor stores energy converted by the alternator from vehicle kinetic energy during vehicle deceleration and releases the stored energy to heat the EHC; and a regenerative braking controller operatively connected to a drivetrain to control a clutch to selectively couple the drivetrain to the engine during deceleration of the vehicle to drive the engine at a speed above an engine idle speed, thereby driving the alternator through the FEAD and converting vehicle kinetic energy to electrical energy to store in the ultracapacitor.
