Definitions
- the invention relates to an automated transmission and a method for controlling a creep torque in the transmission of a vehicle.
- automated manual transmissions and parallel shift transmissions (PSG) are known as automatic transmissions from vehicle technology. It has been shown that with such transmissions it can happen that the vehicle rolls back briefly when starting on a mountain. This may be because the creep torque on the clutch is only built up when the driver has released the brake.
- the invention has for its object a transmission and a method for controlling a creep torque in an automated transmission
- Propose vehicle, in particular rolling back of the vehicle is avoided when driving uphill.
- This object is achieved, on the one hand, according to the invention by a method for controlling a creeping torque on a clutch in an automated transmission, in which the time of construction and / or the course of the creeping torque is determined as a function of at least one operating parameter of the vehicle. Depending on the selected operating parameter, this can be used to implement an improved creep strategy for the vehicle.
- the brake pressure of the vehicle brake can preferably be used as the operating parameter.
- the method according to the invention can, for. B. implement a hill start aid by building up the creep torque or activating a creep torque at the start of releasing the brake. This can be achieved by the fact that
- Creep torque depending on the brake pressure is built up, for example. It is also possible for any other operating parameters of the vehicle to be used are, with operating parameters any motor, gear size or the like is to be understood. It is possible that the creep torque can also be built up as a function of predetermined driving conditions. Accordingly, rolling back of the vehicle, in particular when driving uphill, can be prevented by creeping moment build-up as early as possible.
- the creep torque is built up when the brake pressure coming from above falls below a defined threshold value. This means that the brake is initially closed and the brake pressure z. B. is slowly reduced because the driver goes with his foot from the brake pedal, for example. The creep torque should only be built up if the vehicle falls below a certain threshold to be determined, in order to prevent the vehicle from rolling back.
- the creep torque on the clutch is built up in a function-dependent manner, preferably on the brake pressure. For example, a steadily increasing creep torque can be built up with decreasing brake pressure until the maximum permissible creep torque is preferably applied to the clutch.
- the creep torque is increased, for example, in a continuously linear, progressive, degressive or also stepwise manner with decreasing brake pressure.
- the method according to the invention thus prevents the creep torque from generally being built up at low brake pressures. Otherwise, the vehicle could not be stopped, for example in the plane, even with slight brake application. Furthermore, continuous creeping against the brake can be prevented by the method for controlling the creep torque according to the invention. This means that fuel consumption when idling and any disturbing vibrations in the vehicle can also be avoided.
- the tactile point determination is combined with the creep strategy in the method according to the invention.
- the method presented proposes a hill start aid in which a creep torque build-up is provided as a function of the brake pressure and the brake pressure threshold value.
- This hill start aid can also be used, for example, in other driving situations and is preferably used in automated manual transmissions (ASG), parallel shift transmissions (PSG) or similar transmission systems.
- the object of the invention can be achieved by an automatic transmission for a vehicle, in which at least one device for controlling a creep torque is provided as a function of at least one operating parameter.
- the transmission according to the invention can preferably be used to carry out the proposed method.
- the device preferably has at least one sensor or the like for recognizing the operating parameter.
- a hill start aid for the vehicle is advantageously implemented in which, for example, as the operating parameter.
- B. the brake pressure of the vehicle brake is used.
- FIG. 1 shows a flow diagram of a method according to the invention
- FIG. 2 shows a course of the creep torque as a function of the brake pressure
- Figure 3 shows a sudden curve of the creep torque depending on the
- FIG. 4 shows a course of the creeping torque as a function of the brake pressure, with a low creeping torque when closing and an increased creeping torque when opening the brake.
- FIG. 1 The method according to the invention is illustrated in FIG. 1 using a flow chart.
- Vehicle brake is less than a threshold value p_Brems_Schwelle the brake pressure. If not, the process is ended without the creep torque building up. If so, z. B. builds up a creep torque depending on the falling brake pressure so that the vehicle does not roll back on a slope when releasing the brake.
- FIGS. 2 to 4 show various possible functional relationships between the brake pressure p_Brems_neu and the creeping torque, the course of the creeping torque when the brake is opened being indicated by a solid line and the course of the creeping torque when the brake is applied is indicated by a dotted line.
- the creep torque is built up in a ramp shape when the brake pressure p_Brems_neu drops to open the brake.
- the creeping moment builds up suddenly.
- a curve of the creep torque is shown in FIG. 4, a slight one when the brake is applied
- Creep torque and an increased creep torque is provided when the brake is opened.
