Fig. 1 has schematically demonstrated the fundamental composition that is used to realize a preferred embodiment of the self-running control system of engine health of the present invention with the block diagram mode.
As shown in Figure 1, in this preferred embodiment, it comprises signals collecting subtense angle, starting RACS and starting executive subsystem.Generally; At first pass to the starting RACS by the signals collecting subtense angle signal that the self-starting motor is required; Whether judge whether to pilot engine and to start safety by the starting RACS then; Pilot engine if desired and start safety, then realize the self-starting of motor through the starting executive subsystem.Below will combine Fig. 1 to come this is elaborated, so that be expressly understood working principle of the present invention and characteristics and advantage more.
See also Fig. 1, the signals collecting subtense angle comprises human and machine interface unit 31, first kind sensor (for example illustrated neutral gear position sensor 35, declutched position sensor 36), second type of sensor 32, gateway 33 and network node 34 etc.Wherein, human and machine interface unit 31 is to be used to provide man-machine information interaction function.Above-mentioned first kind sensor and second type of sensor then all are to be installed on the vehicle because the operating parameter signal of monitor vehicle; And the signal that relates to vehicle launch safety is provided by the former; The signal that the latter provides does not then relate to vehicle launch safety, and second type of such sensor comprises but be not limited to car door position transducer, seat belt sensor, battery status sensor, vacuum sensor etc.For gateway 33, it is to be used for gathering the information of human and machine interface unit 31 and/or the signal of second type of sensor 32, and it is delivered to In-vehicle networking 4 (for example, CAN network etc.).On In-vehicle networking 4, also be provided with one or more network nodes 34, they comprise that gearbox control, car body controller, vehicle body stablize control unit, steering angle sensing unit and meter unit.
Below will introduce the starting RACS, it is another important component part that originally is used for realizing the self-running control system of engine health.
Please again with reference to figure 1, the starting RACS mainly comprises starting main control unit 21 and the auxilliary control of starting unit 22, and they interconnect and communicate.Wherein, The operation self-starting gets control logic in starting main control unit 21; And it also interconnects with above-mentioned gateway 33, network node 34 and first kind sensor and communicates; So that the signal through reception sends judges whether Transmitted chains breaks off; And be identified at Transmitted chains and break off and need pilot engine the time; Master relay 11 (will detail subsequently) by in the starting main control unit 21 indication starting executive subsystems carries out the adhesive operation; And starting main control unit 21 also the first kind sensor signal through relatively receiving, the first kind sensor signal that receives by the auxilliary control of starting unit 22 by it the two whether logically be consistent: if consistent, then carry out the self-starting operation, operate otherwise do not carry out self-starting by the starting arrangement 13 (will detail subsequently) in the starting main control unit 21 indication starting executive subsystems.
In the present invention, self-running safe Rule of judgment is also judged in the auxilliary control of starting unit 22 except in starting main control unit 21, judging.The auxilliary control of this starting unit 22 interconnects with gateway 33, network node 34 and first kind sensor and communicates; Thereby judge through the signal that receives whether Transmitted chains breaks off, and be identified when breaking off at Transmitted chains and carry out the adhesive operation by the auxilliary controlled relay 12 in its indication starting executive subsystem.
As shown in Figure 1 again, in this preferred embodiment, the starting executive subsystem comprises master relay 11, auxilliary controlled relay 12 and starting arrangement 13.Wherein, Master relay 11 all is connected with auxilliary controlled relay 12, starting main control unit 21; Assist controlled relay 12 and then all be connected communication with master relay 11, starting arrangement 13 and the auxilliary control of starting unit 22, the master relay 11 in Fig. 1 is connected in series with the load end demonstration of auxilliary controlled relay 12.For starting arrangement 13, it is the parts that are used for finally realizing start-up function in the native system, for example is arranged on the actuating motor in the motor.In Fig. 1, starting arrangement 13 is illustrated out through feedback signal circuit 37 and starting main control unit 21 and communicates in order to the latter feedback signal to be provided, and such feedback signal comprises the work state information of starting arrangement 13 etc.It is to be noted; Starting arrangement 13 only is all could carry out the self-starting operation under the situation of adhesive at master relay 11 and auxilliary controlled relay 12 in the present invention; To be starting arrangement 13 think at starting main control unit 21 that safety and the auxilliary control of starting unit 22 are also thought simultaneously just can carry out work under the safe situation, thereby significantly improves and reliably guaranteed self-running safety control performance.
In other numerous embodiments of the present invention, can also be directed against above-mentioned each constituent element change that is used for realizing the self-running control system of engine health of the present invention.
For example; In a unshowned embodiment; Starting main control unit 21 also comprises the security alarm module; It is to be provided for when the viscous fault all appears in master relay 11 and auxilliary controlled relay 12, forbids that by this security alarm module starting arrangement 13 carries out the self-startings operation and warn through the meter unit in the operator cabin, this fault occurs to remind driver and passenger.
In another unshowned embodiment; In starting main control unit 21, also be provided with the operating time that time control module is used for controlling starting arrangement 13, and preferably can set according to actual needs or adjust by manufacturer, user or attendant through human and machine interface unit 31.
In addition, although starting main control unit 21 and the auxilliary control of starting unit 22 can be through shared line from obtaining signal such as first kind sensors such as aforesaid neutral gear position sensor 35, declutched position sensors 36.But; In order to realize reliable more, effectively safety control; In yet another preferred embodiment; Each first kind sensor all has the fully independently first output line road and secondary signal outlet line, so that be connected respectively to starting main control unit 21 and the auxilliary control of starting unit 22 through not related each other outlet line, thereby further promotes the safety control performance.
In addition, in another example, the voltage-controlled actuating motor of common 12V that starting arrangement 13 adopts.Certainly, if need to adopt the motor under other suitable voltages according to actual needs, this also is fully feasible.
More than enumerated some specific embodiments and come that sets forth in detail is of the present invention to be used to realize the self-running control system of engine health; These a few examples only supply to explain the usefulness of principle of the present invention and mode of execution thereof; But not limitation of the present invention; Under the situation that does not break away from the spirit and scope of the present invention, those of ordinary skill in the art can also make various distortion and improvement.Therefore all technological schemes that are equal to all should belong to category of the present invention and limited by each item claim of the present invention.
