[embodiment]
Fig. 1 has schematically demonstrated of the present invention for realizing the fundamental composition of a preferred embodiment of the self-running control system of engine health in block diagram mode.
As shown in Figure 1, in this preferred embodiment, it comprises signals collecting subtense angle, starting control subsystem and starting executive subsystem.Generally, first by signals collecting subtense angle, signal required self-starting motor is passed to starting control subsystem, then by starting control subsystem, whether judge whether to pilot engine and to start safety, if need to pilot engine and start safety, by starting executive subsystem, realize the self-starting of motor.Below with reference to Fig. 1, this is elaborated, so that be more expressly understood working principle of the present invention and feature and advantage.
Refer to Fig. 1, signals collecting subtense angle comprises human and machine interface unit 31, first kind sensor (such as illustrated neutral gear position sensor 35, declutched position sensor 36), Equations of The Second Kind 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 Equations of The Second Kind sensor are to be all installed in the operating parameter signal due to monitor vehicle on vehicle, and by the former, provided the signal that relates to vehicle launch safety, the signal that the latter provides does not relate to vehicle launch safety, and such Equations of The Second Kind sensor includes, but are not limited to car door position transducer, seat belt sensor, battery status sensor, vacuum sensor etc.For gateway 33, it is information for gathering human and machine interface unit 31 and/or the signal of Equations of The Second Kind sensor 32, and is delivered to In-vehicle networking 4 (for example, CAN network etc.).On In-vehicle networking 4, be also 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 starting control subsystem, it is that this is for realizing another important component part of the self-running control system of engine health.
Refer again to Fig. 1, starting control subsystem mainly comprises starting main control unit 21 and starting auxiliary control unit 22, and they interconnect and communicate.Wherein, in starting main control unit 21, move self-starting and obtain control logic, and it also with above-mentioned gateway 33, network node 34 and first kind sensor interconnect and communicate, so that whether the signal sending by reception judges Transmitted chains and disconnects, and be identified when disconnecting and need to pilot engine at Transmitted chains, by starting main control unit 21, indicating the master relay 11 (will describe in detail subsequently) starting in executive subsystem to carry out adhesive operates, and starting main control unit 21 is also by the first kind sensor signal relatively being received by it, whether the first kind sensor signal being received by starting auxiliary control unit 22 the two be logically consistent: if consistent, by starting main control unit 21, indicate starting arrangement 13 (will describe in detail subsequently) the execution self-starting in starting executive subsystem to operate, otherwise do not carry out self-starting operation.
In the present invention, self-running analysis condition, except judging in starting main control unit 21, also judges in starting auxiliary control unit 22.This starting auxiliary control unit 22 interconnects and communicates with gateway 33, network node 34 and first kind sensor, thereby by the signal receiving, judge whether Transmitted chains disconnects, and be identified and by the auxiliary control relay 12 in its indication starting executive subsystem, carry out adhesive while disconnecting and operate at Transmitted chains.
Again as shown in Figure 1, in this preferred embodiment, starting executive subsystem comprises master relay 11, auxiliary control relay 12 and starting arrangement 13.Wherein, master relay 11 is all connected with auxiliary control relay 12, starting main control unit 21, auxiliary control relay 12 is all connected communication with master relay 11, starting arrangement 13 and starting auxiliary control unit 22, and the master relay 11 in Fig. 1 shows and is connected in series with the load end of auxiliary control relay 12.For starting arrangement 13, it be in native system for finally realizing the parts of start-up function, be for example arranged on the actuating motor in motor.In Fig. 1, starting arrangement 13 is illustrated out by feedback signal circuit 37 and starting main control unit 21 and communicates in order to provide feedback signal to the latter, and such feedback signal comprises the work state information of starting arrangement 13 etc.It is to be noted, starting arrangement 13 is only at master relay 11 and auxiliary control relay 12, all could carry out self-starting adhesive in the situation that to operate in the present invention, being starting arrangement 13 thinks that at starting main control unit 21 safety and starting auxiliary control unit 22 just can carry out work in the situation that of also thinking safe simultaneously, thus significantly improve and Reliable guarantee self-running safety control performance.
In other numerous embodiments of the present invention, can also be for of the present invention for realizing above-mentioned each constituent element change of the self-running control system of engine health.
For example, in a unshowned embodiment, starting main control unit 21 also comprises security alarm module, it is to be provided for when viscous fault all appears in master relay 11 and auxiliary control relay 12, by this security alarm module, forbid that starting arrangement 13 carries out that self-starting operates and warned by the meter unit in operator cabin, to remind driver and passenger to occur this fault.
In another unshowned embodiment, in starting main control unit 21, be also provided with time control module and be used for controlling the operating time of starting arrangement 13, and preferably can by manufacturer, user or attendant, set according to actual needs or adjust by human and machine interface unit 31.
In addition, although starting main control unit 21 and starting auxiliary control unit 22 can obtain signal from first kind sensors such as all sensors of neutral gear position as the aforementioned 35, declutched position sensors 36 by shared line.But, in order to realize more reliable, effectively safety control, in yet another preferred embodiment, each first kind sensor has completely independently first signal outlet line and secondary signal outlet line, to be connected respectively to starting main control unit 21 and starting auxiliary control unit 22 by not associated each other outlet line, thereby further promote 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 according to actual needs the motor under other suitable voltages, this is also feasible.
More than having enumerated some specific embodiments illustrates of the present invention for realizing the self-running control system of engine health in detail, these a few examples are only for explanation principle of the present invention and mode of execution thereof, but not limitation of the present invention, without departing 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 also by every claim of the present invention is limited.
