Definitions
- the invention relates to a method for increasing the safety of a hybrid vehicle, in which a hybrid disconnect clutch separates or connects an internal combustion engine and an electric motor and the torque output by the internal combustion engine and / or the electric motor is transmitted to drive wheels of the hybrid vehicle.
- hybrid vehicles which allow different combinations of types of drive, such as electric motor, elektrozeratorisch, internal combustion engine in push or pull operation, internal combustion engine or electric motor OFF, a mechanical decoupling of the moments of the internal combustion engine and electric motor is necessary.
- the decoupling of internal combustion engine and electric motor is typically carried out by a hybrid disconnect clutch, which is automatically actuated.
- This automatic actuation of the hybrid disconnect clutch via an actuator, consisting of a control unit with a corresponding software for controlling the electromechanical or electro-hydraulic actuator, which actuates the clutch.
- an actuator consisting of a control unit with a corresponding software for controlling the electromechanical or electro-hydraulic actuator, which actuates the clutch.
- incorrect control by the control device may cause the hybrid disconnect clutch to close, which may lead to safety problems when driving the hybrid vehicle.
- Measures which are known to increase the safety of the hybrid vehicle in such an error case consist in that a further clutch which is arranged in a typically downstream transmission, in a protective mode by the downstream clutch is fully or partially opened.
- the invention has for its object to provide a method for increasing the safety of a hybrid vehicle, which is used to prevent safety risks in a faulty opening of the hybrid disconnect coupling.
- the object is achieved in that when using the electric motor as a drive motor in a fault of the hybrid disconnect clutch, a speed of the engine is limited to the current speed of the electric motor. Characterized in that the rotational speed of the internal combustion engine does not exceed the rotational speed of the electric motor, an acceleration of the hybrid vehicle can not be carried out so that safety-critical situations that can be caused by an unwanted acceleration of the hybrid vehicle, reliably prevented.
- the rotational speed of the internal combustion engine is set to be smaller than or equal to the current rotational speed of the electric motor when the rotational speed of the electric motor is equal to or above an idling rotational speed of the internal combustion engine.
- This has the advantage that the internal combustion engine continues to operate and can be used, for example, to charge a high-voltage battery of the electric motor, but can not make any contribution to driving the hybrid vehicle.
- ignition of the internal combustion engine is suppressed when the current speed of the electric motor is below the idling speed of the internal combustion engine. This ensures that the combustion engine is not activated and thus makes no contribution to the drive of the hybrid vehicle.
- a torque intervention on the internal combustion engine is performed when there is no limitation of the rotational speed of the internal combustion engine to the current rotational speed of the electric motor above the electric motor rotational speed.
- the speed of the internal combustion engine can be reduced and thus its effect on the drive of the hybrid vehicle can be restricted.
- an ignition intervention takes place on the internal combustion engine. By suppressing ignition of the internal combustion engine, a speed increase of the internal combustion engine can be prevented.
- the rotational speeds of the internal combustion engine and the electric motor are monitored to monitor the fault on the hybrid disconnect clutch.
- a modulation signal is impressed to monitor the fault on the hybrid disconnect clutch of the rotational speed of the electric motor, wherein upon the occurrence of the modulation signal on the rotational speed of the internal combustion engine closed it The hybrid disconnect clutch transmits a moment.
- This monitoring method is particularly advantageous if the hybrid separation clutch is actually to be open. In determining a transmission of the modulation signal on the speed of the internal combustion engine can be safely concluded that the hybrid disconnect clutch is in an unintentionally closed state.
- a development of the invention relates to a method for increasing the safety of a hybrid vehicle, in which a hybrid disconnect coupling separates or connects an internal combustion engine and an electric motor and the torque output by the internal combustion engine and / or the electric motor is transmitted to drive wheels of the hybrid vehicle.
- the safety state of the hybrid vehicle can be increased, when starting with an electric motor, the hybrid disconnect clutch is opened, starting due to a low battery state of a battery of the electric motor, the internal combustion engine for charging the battery, wherein in an unintentional closing of Hyb - Ridentrennkupplung a method is initiated according to at least one feature explained in this patent application.
- 1 is a schematic diagram of a hybrid drive
- Fig. 3 shows an embodiment of the inventive method.
- Fig. 1 is a schematic diagram of a drive train 1 of a hybrid vehicle is shown.
- This drive train 1 comprises an internal combustion engine 2 and an electric motor 3. Between the internal combustion engine 2 and the electric motor 3, a hybrid separating clutch is arranged directly behind the internal combustion engine 2.
- Internal combustion engine 2 and hybrid disconnect clutch 4 are connected to each other via a crankshaft 5.
- the electric motor 3 has a rotatable rotor 6 and a fixed stator 7.
- the output shaft 8 of the hybrid disconnect clutch 4 is connected to a transmission 9, which has a coupling element, not shown further, for example. includes a second clutch or a torque converter, which are arranged between the electric motor 3 and the transmission 9.
- the transmission 9 transmits the torque generated by the internal combustion engine 2 and / or the electric motor 3 to the drive wheels 10 of the hybrid vehicle.
- the electric motor 3 and the transmission 9 form a transmission system 1 1, which is controlled by a hydrostatic clutch actuator 12.
- the hybrid disconnect clutch 4 disposed between the engine 2 and the electric motor 3 is closed to start the engine 2 during travel of the hybrid vehicle 1 with the torque generated by the motor 3, or to drive the engine 2 and the motor 3 during a boost operation.
- the hybrid separation clutch 4 is actuated by the hydrostatic clutch actuator 12.
- the hybrid vehicle In a further operating state, the hybrid vehicle is approached from the state with the electric motor 3.
- the internal combustion engine 2 is stationary, with the hybrid separating clutch 4 being open.
- FIG. 2a shows the speed NIce of the engine 2 and the speed NEMot of the electric motor 3 over time.
- FIG. 2b shows the current torque Trq_CI transmitted by the hybrid disconnect clutch 4, while FIG. 2c illustrates the request B_Res_lce for starting the internal combustion engine 2.
- the internal combustion engine 2 is started by a low battery state of charge (SOC) of a high-voltage battery of the electric motor 3, which is to charge the battery by an increased charge speed NIce of approximately 1500 rpm.
- SOC battery state of charge
- NIce charge speed
- the hybrid disconnect clutch 4 is open. Since the hybrid disconnect clutch 4 is closed due to the defect of the hydrostatic clutch actuator 12, the hybrid vehicle is unintentionally accelerated from a time of t> 20s, which may result in a critical driving situation.
- FIG. 3 has the same partial diagrams 3 a, 3 b, 3 c as FIG. 2.
- the closing of this hybrid disconnect clutch 4 is initiated. known.
- the detection takes place by monitoring the rotational speeds of the internal combustion engine 2 and the electric motor 3.
- a non-driving comfort-relevant modulation signal is impressed on the rotational speed of the electric motor 3.
- This modulation signal may be, for example, a 30 Hz sinusoidal oscillation with a low momentum amplitude. If the hybrid disconnect clutch 4 is closed as in the present case, this modulation will occur on the speed signal of the internal combustion engine 2. This can be checked by correlation or log-in procedures. Based on this evaluation, it is reliably determined that the clutch is not open.
- the hybrid disconnect clutch 4 since it is known that the hybrid disconnect clutch 4 is not open, a speed mode is set at the internal combustion engine 2, which limits the speed NIce of the internal combustion engine 2 to the actual rotational speed NEMot of the electric motor 3.
- the speed NIce of the internal combustion engine 2 will not be higher than the speed NEMot of the electric motor 3.
