Systems and/or methods for controlling dual motor-dual clutch powertrains for HEV and PHEV vehicles are disclosed. In one embodiment, a method is disclosed comprising: determining the state of charge (SOC) of said batteries; determining the speed of the vehicle; if the SOC is greater than a given first threshold, selecting a charge-depleting operational mode of said vehicle; during operation of said vehicle, if the SOC is less than a given second threshold, selecting a charge-sustaining operating mode of said vehicle. In another embodiment, a system having a controller that operates the powertrain according to various embodiments is disclosed. |

1. A method for controlling the powertrain for an HEV vehicle, said powertrain for said HEV vehicle comprising a prime mover; an electric motor-generator, said electric motor-generator mechanically coupled to said prime mover via a first clutch; an electric motor, said electric motor mechanically coupled to said electric motor-generator via a second clutch; a battery, said battery electrically coupled to said electric motor-generator and said electric motor, said battery configured to supply electrical energy to said electric motor-generator and said electric motor; and a controller, said controller configured to receive signals from one or more sensors and supplying control signals to said prime mover, said first clutch, said electric motor-generator, said second clutch and said electric motor such that said controller is configured to dynamically affect a plurality of operating modes; the steps of said method comprising:
determining the state of charge (SOC) of said batteries; determining the speed of the vehicle; if the SOC is greater than a given first threshold, selecting a charge-depleting operational mode of said vehicle; during operation of said vehicle, if the SOC is less than a given second threshold, selecting a charge-sustaining operating mode of said vehicle receiving as input SOC values, speed of vehicle value, and engine temperature values; if SOC is greater than a first threshold, selecting an operational mode from one of a group, said group comprising: all-electric mode and high-traction electric mode; if SOC is below said first threshold in (ii) and if engine temperature is below a first temperature threshold, selecting an operational mode from one of a group, said group comprising: all-electric mode and series hybrid mode; if engine temperature is above a first temperature threshold in (iii) and if SOC is below a second threshold and if speed of vehicle is below a first speed threshold, selecting an operational mode from one of a group, said group comprising: all electric mode; if speed of vehicle is above said first speed threshold in (iv), selecting an operational mode from one of a group, said group comprising: parallel hybrid mode; if SOC is not below said second threshold in (iv) and if speed of the vehicle is above a second speed threshold, selecting an operational mode from one of a group, said group comprising: parallel hybrid mode; and if speed of vehicle is not above a second speed threshold in (vi), selecting an operational mode from one of a group, said group comprising: series hybrid mode. |
