Definitions
- Control system with at least one electronic control unit for
- the invention relates to a control system with at least one electronic control unit for controlling an internal combustion engine in a hybrid vehicle.
- Hybrid vehicles which contain at least one internal combustion engine and at least one electric motor as drive motors.
- Hybrid vehicles of this kind have control systems with at least one electronic control unit which, in particular by means of suitably programmed function modules, perform different operating methods for selecting an operating mode adapted to the respective current driving situation.
- Selectable operating modes are in particular purely electric driving (only the electric motor drives on, "E-mode", “E-driving”), pure
- Internal combustion engine driving (only the internal combustion engine is driving) and / or hybrid driving (both the electric motor and the internal combustion engine are driving).
- known operating methods take into account the state of charge of the battery or other electrical storage (eg, super-cap) for selecting the operating mode.
- parameters such as the current vehicle speed, the current driving behavior or certain currently set customer functions are taken into account.
- Patent claim 1 solved.
- Advantageous developments of the invention are contained in the dependent claims.
- the invention generally comprises a method for controlling the starting and stopping of an internal combustion engine in a hybrid vehicle, wherein by means of an assessment of the current situation and situations, preferably in a defined Vorschau Schl, with regard to an expected speed course and preferably also to a load curve depending from a driver interaction and / or the state of charge of the high-voltage storage the Zustart- and Ablege in a defined manner, which will be discussed in more detail below, is optimized.
- data for recognizing a current situation and for detecting at least one in the near future e.g.
- Such data for predicting the speed history include
- Map data on environment and / or traffic guidance information from navigation systems eg ADAS with RTTI
- navigation systems eg ADAS with RTTI
- driver-specific learning systems for forecasting the most likely ones ahead route, to forecast speeds in ahead curves, to capture leading and current speed limits, to forecast the one ahead
- Sign recognition systems e.g., KAFAS
- KAFAS Sign recognition systems
- upstream and relevant signal light system detection of the traffic light state
- Vehicle sensors e.g., radar and KAFAS for detection
- At least one driver interaction in particular by the detection of the accelerator pedal position of the respective current load request, determined.
- the starting and stopping of the internal combustion engine is primarily controlled as a function of the expected speed profile as well as the expected load curve in the predetermined forecast horizon and preferably also by the current driver interaction.
- the support and Ablege depends on the operating condition of the vehicle, in particular the state of charge of the
- Charge state of the battery dependent load limits are exceeded or undershot.
- the new situation (s) lying in the near future can, according to the invention, lead to the (stepless) shift up and down and / or to the ignoring of these previously autonomously predetermined delivery limits.
- control by means of the control system according to the invention or the method according to the invention for controlling the starting or depositing of an internal combustion engine is carried out in a defined manner, namely preferably in such a way that
- the depositing of the internal combustion engine is prevented when a delay only a brief shortfall of the E-speed limit is expected.
- a restart of the engine is prevented shortly after its deposition.
- the internal combustion engine is (early) stored with the load removal, if a long-lasting load-free drive or deceleration is to be expected (eg sailing on a downhill slope). This is preferably the case when the
- the starting of the internal combustion engine is prevented in principle without load request, as long as no acceleration is to be expected or is undertaken. That a Zustart the internal combustion engine is if possible by a
- a starting of the internal combustion engine is already at the beginning of a Acceleration process and not only after exceeding the currently valid e-driving speed limit, ie possibly under high load of the internal combustion engine, made if the expected speed curve, exceeding either of these limits or a battery discharge is predictable.
- a load-induced start of the internal combustion engine is prevented, as long as the expected speed curve is continuously below the currently valid e-driving speed limit (for example due to a
- the brief stoppage of the internal combustion engine during short vehicle stops is prevented, as long as the low charge state of the high-voltage storage does not allow electric driving.
- a further advantageous embodiment of the invention provides for reliable detection of an incipient overtaking operation (for example with the aid of
- Front vehicle at the same time low traffic density, etc. an early start of the internal combustion engine.
- the goal is to increase the response and dynamics for the overtaking process.
- Control unit designed such that a states of the Internal combustion engine to a later upcoming

- the output signal FP and the expected speed curve v e determined in the look-ahead module 3 are input signals of a control function module 5, which is also part of the control unit.
- the control function module 5 preferably contains a software program product, by means of which the operating strategy of the
- the operating strategy is based on the following state of the art: If the current valid e-speed limit eVwax is exceeded by the actual speed, the internal combustion engine is filed according to the prior art. If the currently valid e-speed limit eVwax is exceeded by the actual speed, becomes according to the state of the art of the internal combustion engine immediately

- the second situation S2 indicates by the recognition of the
- the current situation SO is a purely electrical constant drive outside the locality with, for example, 60 km / h, well below the currently valid e-speed limit eVMax.cD (or eVwax.cs). Also on the route ahead (situation S1 and S2) no increase of the expected speed is predicted. If the driver requires a brief load peak LS, for example for crossing a yellow traffic light phase, according to the current state of the art, when the speed-dependent load limit is exceeded, the combustion engine starts up and shuts off again after a short time. According to the invention prevents one
- Delivery robustness is an increase in efficiency and e-driving experience as well as a reduction in the number of internal combustion engine states in customer operation.
- Fig. 1-7 show only examples of an expected speed curve, which may give all the information mentioned above.
- other examples such as an early start of the internal combustion engine before a recognized overtaking or Abschaltverhinderer for short-term stops (stop sign, traffic light with a short residual red phase, etc.) are not shown separately.
