Definitions
- the present invention relates to a vehicle with a drive train and a method for controlling and / or regulating the drive train of a vehicle, comprising at least one engine and a transmission, wherein at least one engine control and one transmission control are used for control and / or regulation.
- Vehicles with a drive train comprising an engine and a transmission, and methods for controlling and / or regulating the drive train of the vehicle are known.
- the transmission control or at least one clutch actuator fails in the course of an overlap shift.
- this failure can be caused by the destruction of a fuse or the like.
- Clutches permanently transmit moments to the output or to the wheels, the driver releases the accelerator pedal and the engine switches to overrun, especially when the vehicle is on a smooth, icy surface, for example.
- the invention is therefore based on the object of proposing a vehicle with a drive train and a method for controlling and / or regulating the drive train of a vehicle, in which the engine and the transmission are controlled in such a way that in particular the aforementioned safety-critical driving situations are avoided.
- this object can be achieved by a method for controlling and / or regulating a drive train of a vehicle, comprising at least one engine and a transmission, wherein at least one engine control and one transmission control is used for the control and / or regulation, in which by the engine control preferably at least one torque control is carried out when a malfunction of the transmission control is detected, in order to prevent or end a detachment from the wheels of the vehicle.
- the engine control is influenced by the inventive method such that, for. B. the aforementioned safety-critical driving situations can be avoided.
- the inventive method such that, for. B. the aforementioned safety-critical driving situations can be avoided.
- the engine control it can be determined by the engine control whether the transmission control z. B. has failed and the two clutches of a parallel transmission or a clutch of an automated transmission permanently transmit torque. If this is the case, a special engine drag torque control can be used in the Motor control can be activated to avoid a safety-critical driving situation in the vehicle.
- the transmission control for detecting a malfunction or a failure of the transmission control, for. B. emergency operation information or the like is output by the transmission control.
- emergency operation information or the like is output by the transmission control.
- an emergency bit or the like via a vehicle network, such as. B. the CAN are sent to the engine control.
- the engine control can then preferably activate the engine drag torque control.
- a further possibility for recognizing a malfunction of the transmission control unit can be that the engine control system independently recognizes that the transmission control or clutch control has failed completely, for example.
- An indication of a failure can e.g. B. the missing update of the CAN messages from the transmission control unit or the like; for example if the values do not change and the message counter is frozen.
- the engine drag torque control can also be used, for. B. be activated during a reset or the like in the transmission control or in the clutch control.
- the maximum drag torque is limited in the torque control, preferably in overrun mode. In this way, the engine control system prevents a maximum drag torque from occurring at the output.
- Another possibility can provide that the engine control a
- the engine torque z. B. can be set to a value between 0 Nm and a smaller negative value when the accelerator pedal is not actuated.
- the torque control can delay the implementation of the thrust torque desired by the driver.
- the engine control can only build up the decelerating thrust very slowly. If, despite the mentioned and other possible measures, a detachment of the vehicle should occur, it can be provided according to a development of the invention that the engine torque z. B. is increased (reduce drag torque) until the wheels stick again. In this way, the drag torque can be regulated at the trap limit.
- the engine control system can determine a detachment from the speed comparison of the driven and the non-driven wheels.
- the driver also has the option of actively decelerating the vehicle by actuating the brake pedal, in which case the other systems contained in the vehicle, such as. B. ABS, ESP or the like, can ensure driving stability for themselves.
- the object on which the invention is based can be achieved in terms of the device by a vehicle having a drive train comprising at least one engine and a transmission, which can be controlled at least via an engine control unit and a transmission control unit, in particular for carrying out the proposed method, in which the engine control unit at least has a torque control which can be activated upon detection of a fault in the transmission control unit.
- the engine control unit at least has a torque control which can be activated upon detection of a fault in the transmission control unit.
- Figure 1 is a schematic diagram of a vehicle with an engine and a dual clutch transmission
- FIG. 2 shows a flow diagram of a possible exemplary embodiment of the method according to the invention
- Figure 3 shows the curves of the engine torque with and without reduced
- Figure 4 shows the curves of the engine torque with and without delayed
- Figure 5 shows the curves of the speeds of the driven and non-driven wheels
- Figure 6 shows the normal course of the engine torque and the reduced
- FIG. 1 shows a basic diagram of a vehicle 101 with an engine 106 and a double clutch transmission with a first partial transmission 102 and a second partial transmission 103, each partial transmission 102, 103 comprising a clutch 104, 105.
- FIG. 1 shows, by way of example, two power flows, namely the drag loss on the engine and the friction loss on the clutch 105 through the drive train when the clutches 104 and 105 are frozen when the engine 106 is coasting. The drag power from motor 106 and second clutch 105 add up at the output.
- the output torque M ab can be calculated, for example, using the following formula:
- M ab M mot • -. + M K2Schll ⁇ f • sign (n Mot - n 2 ) ⁇ (i 2 - i,)
- FIG. 2 schematically shows a flow diagram of a possible exemplary embodiment of the method according to the invention for activating the engine drag torque control in the engine control.
- the engine control no longer permits the maximum drag torque in overrun mode, so that the drag torque is set to the value 0 Nm or a small negative value when the accelerator pedal is not actuated, as is also shown in FIG. 3. This corresponds to the special engine drag torque control with low drag torque.
- FIG. 5 shows the course of the rotational speeds of the driven and the non-driven wheels over time, the speed course of the non-driven wheels being marked with a dotted line and the speed course of the driven wheels being marked with a solid line.
- FIG. 6 shows the normal course of the engine torque and a reduced course of the engine torque at the tire grip limit, the normal course being identified by a dash-dotted line and the reduced course by a solid line.
- FIG. 6 shows the special engine drag torque control with reduced drag torque, the drag torque being controlled at the adhesion limit.
