Abstract
The disclosed hybrid vehicle (1) includes: an engine (3) mounted in a vehicle (1) and to which an EGR system (2) is applied; a motor (4) having a function of driving the vehicle (1) and a function of performing power regeneration; a battery (5) into which electric power generated by the power regeneration is charged. Further, the hybrid vehicle (1) includes: a generator (6) coupled to the engine (3) and having a function of driving the engine (3) with electric power of the battery (5); and an EGR valve (11) interposed in an EGR passage (10) connecting an intake system (8) and an exhaust system (9) of the engine (3). Furthermore, the hybrid vehicle (1) includes a control unit (13) that performs, in the power regeneration, an idle circulation control that idly drives the engine (3) by the generator (6) while opening the EGR valve (11).
Claims5
A hybrid vehicle comprising:
- an engine mounted in a vehicle and to which an exhaust gas recirculation (EGR) system is applied;
- a motor having a function of driving the vehicle and a function of performing power regeneration;
- a battery into which electric power generated by the power regeneration is charged;
- a generator coupled to the engine and having a function of driving the engine with electric power of the battery;
- an EGR valve interposed in an EGR passage connecting an intake system and an exhaust system of the engine;
- and
- a control unit that performs, in the power regeneration, an idle circulation control that idly drives the engine by the generator while opening the EGR valve, wherein
- the control unit increases, in the idle circulation control, an aperture of the EGR valve as a pressure of the intake system decreases.
