| 发明名称 | Thermal model for dry dual clutch transmissions | ||
| 摘要 | A method of determining temperatures for a dry dual clutch mechanism includes one or more steps, such as determining a first heat input from a first clutch and determining a second heat input from a second clutch. The second clutch is separated from the first clutch by a center plate. The method also includes determining a housing air temperature of housing air within a bell housing case of the dry dual clutch mechanism. A thermal model is applied with the determined first heat input and second heat input. The thermal model includes temperature states for at least the first clutch, the second clutch, and the center plate. From the thermal model, the method determines at least a first clutch temperature and a second clutch temperature. The method includes executing a control action with the determined first clutch temperature and second clutch temperature. | ||

| 主权项 | 1. A method of determining temperatures for a dry dual clutch mechanism, comprising: determining a first heat input from a first clutch; determining a second heat input from a second clutch, which is separated from the first clutch by a center plate; determining a housing air temperature of housing air within a bell housing case of the dry dual clutch mechanism; applying a thermal model using the determined first heat input and second heat input, wherein the thermal model includes temperature states for the first clutch, the second clutch, and the center plate; determining a first clutch temperature from the thermal model; determining a second clutch temperature from the thermal model; and executing a control action using the determined first clutch temperature and the determined second clutch temperature, wherein the control action includes determining a first coefficient of friction from the determined first clutch temperature and determining a second coefficient of friction from the determined second clutch temperature, and includes selectively transferring torque across one of the first clutch and the second clutch. | ||
