Therefore, can analyze by data, signal and/or the information of vehicle bus 12 requests many by diagnostic device 16, so that whether diagnosis (particularly) can guarantee desirable performance reliably with the synergistic vehicle part of electrically powered machine.
In addition, diagnostic device 16 can be designed to be able to confirm that according to the charge condition of temperature, energy storage and/or the current rotating speed of at least one wheel maximum can realize moment of torsion.In this case, diagnostic device 16 limit value of confirming the power that at least one electrically powered machine needs provide according to charge condition and/or at least one current rotating speed of temperature, energy storage.Such power regulation is that chaufeur is guaranteed best driver comfort through maximum attainable effective power is provided for vehicle, has avoided vehicle part overload to occur simultaneously.
Fig. 4 shows a system of axes, can realize moment of torsion so that show the maximum that a charge condition through energy storage, rotating speed that Current Temperatures and at least one wheel reached limit.In the system of axes of Fig. 4, the rotation speed n that on behalf of at least one wheel, abscissa reach.The corresponding maximum of ordinate can realize moment of torsion M.
A kind of relation between corresponding separately (when not considering energy storage charge condition and the Influence of Temperature) rotation speed n of figure line 50 and 52 and maximum attainable (left side or right side) moment of torsion M.Here can pick out, on limit speed nx, along with the increase of rotation speed n, maximum attainable moment of torsion M constantly reduces.
The temperature that provided straight line 54 and 56 can realize the additional limits of moment of torsion M to maximum.This restriction of temperature at first occurs when rotation speed n is lower than limit speed nx.
In addition, in the system of axes of Fig. 4, shown that through curve 58 and 60 charge condition of energy storage (for example Vehicular battery) can realize the restriction of moment of torsion M to maximum.The restriction that charge condition can be realized moment of torsion M to maximum preferably (especially) when rotation speed n is higher than limit speed nx, observe.
Preferably diagnostic device 16 is designed to be able to pair can realize that with the corresponding maximum of Fig. 4 moment of torsion M confirms according to the charge condition of temperature, energy storage and/or at least one rotating speed.Correspondingly, also can the charge condition (battery state of charge) that diagnostic device 16 is designed to be able to depend on a voltage, rotating speed and/or energy storage be confirmed the restriction of storage battery power.
But the use of this title of " diagnostic device 16 " should not be construed as, and the functional limitation of diagnostic device 16 is in diagnosis function.As to this replenish, diagnostic device 16 can be configured to " virtual driving person ", promptly can export the control signal that is used for implementing to advance automatically (Boost).But do not take graphics mode to show for this function of diagnostic device 16 here.
As shown in Figure 2, if diagnostic device 16 is placed in the outside of control setup 10, it can be connected with data, signal and/or the information receiver 62 of control setup 10 through centre bus 18 so.Preferably, vehicle bus 12 also can be connected on data, signal and/or the information receiver 62.Therefore, control setup 10 also can directly receive data, signal and/or information from vehicle bus 12.Through internal data, signal and/or an information carrying means (for example through an internal bus 64), data, signal and/or information receiver 62 confirm that with the mode of control setup 10 device 66 is connected.
This mode confirms that device 66 also can be known as state automata, because can confirm through it speed control system that vehicle is own and (particularly) electrically powered machine should be transformed among which kind of state (electrical generator and/or electrical motor mode, mode of operation).Therefore, mode is confirmed the decision package of device 66 corresponding to central authorities, in order to the mixed function of confirming that this mixed system/speed control system need be carried out.Electrical generator and/or the Duty of Electric Motors of utilizing mode to confirm that device 66 can be confirmed can be, for example power actuated vehicle is only with electric traveling/acceleration (E-Drive), regeneration, propulsion mode (Boostmodus), take turns type of drive, Load lifting mode, load reduction mode and/or idle running mode (Free-Wheeling) entirely.
Below, mode is confirmed a kind of preferred embodiment of device 66 describes:
The mode that schematically shows among Fig. 2 confirms that device 66 is configured to need to confirm the favourable electrical generator and/or the electrical motor mode (the specified mode of electrical generator and/or electrical motor) that start/keep according to velocity variations information 67 (this information is relevant with the rapid change that chaufeur is made).Corresponding velocity variations information 67 can be for example about the information of operation Das Gaspedal, power-transfer clutch, brake pedal or in order to start the information of operating input element (especially for button that triggers electric traveling/accelerations and/or propelling button) by the current preferred electrical generator of chaufeur and/or Duty of Electric Motors.
In addition; Mode confirms that device 66 can be by such structure; Promptly when confirming mode of operation, mode confirm device can also note relating to the own parts of at least one vehicle a state a status signal 65 and/or relate to a driving information 69 of the parameter of a description vehicle current driving mode.As replenishing, " the virtual driving person's " who is sent by diagnostic device 16 instruction 17 also can be noted.
When confirming mode of operation, can confirm that the state of the own parts of at least one vehicle that device 66 is noticed preferably can be a charging accumulator status signal 71 and/or signal 30 to 36 information corresponding of describing with the preamble of diagnostic device 16 that relate to the energy storage charge condition by mode.Therefore, when utilizing diagnostic device 16 to distinguish on a vehicle part relevant, occur wrong, also can the mistake that when confirming mode of operation, picks out be taken into account with the own speed control system of vehicle.
The parameter of describing vehicle current driving mode can be the rotating speed of for example real-time speed, real time acceleration, at least one wheel, real-time angle of inclination and/or real-time angle of inclination variable quantity.But the parameter that can consider, be used for describing vehicle current driving mode is not limited thereto the example that the place is enumerated.
Preferably, mode confirms that device 66 can be designed to like this, and promptly it can be used for need confirming the condition of enforcement/preferred electrical generator and/or Duty of Electric Motors to assess to those through a kind of method to misinterpretation (True-Fault-Bewertung).This has just guaranteed to pass judgment on the condition that is applicable to all electrical generators and/or Duty of Electric Motors/hybrid mode reliably.Therefore, mode confirms that device 66 can distinguish according to the data that provided, and regeneration, advances or takes turns the transmission mode of operation entirely current whether favourable.Therefore just can prevent for example following situation: start the electric traveling mode when in energy storage, not having electric energy, when energy storage is in Full Charge Capacity and/or is close to Full Charge Capacity, start the reproduction operation mode.
Here it is emphasized that; Mode confirms that device 66 only detects from existence/maintenances that one first operation scheme is transformed into a few gentle transition condition of one second operation scheme being used for the speed control system that vehicle is own, and/or just can note the existence/maintenance of these conditions when the electrical generator only readjusted at the needs of definite this speed control system and/or Duty of Electric Motors.Therefore, when the electrical generator of confirming this speed control system and/or Duty of Electric Motors, do not need the transition condition (need detect these transition conditions when between two kinds of mode of operation, changing in a conventional manner) of a large amount of and/or strict restriction.
Therefore, mode confirms that device 66 is such design-calculateds, and promptly compared with prior art, this device at the transition condition of confirming the mode of operation time institute foundation that needs start obviously still less.In addition, mode confirms that the transition condition that device 66 is considered can be provided with like this, promptly makes this condition can not cause the significant limitation to the quick conversion between two kinds of mode of operation.Especially, the transition condition of being considered can be gentle transition condition, these transition conditions in many standard compliant vehicles and/or traffic conditions all be what to exist/can be met.Therefore, as long as can detect, so transition condition is considered just can not cause the obstruction to quick conversion.
Pass-through mode is confirmed this kind design of device 66; Guarantee that electrically powered machine can " not be absorbed in " in certain mode; Although the goal-selling according to chaufeur can be distinguished the preferred a kind of vehicle ' mode of chaufeur,, this kind take another mode of operation perhaps more suitable under going mode.Therefore mode confirms that the design of device 66 has improved the driver comfort of chaufeur.
