Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model is by fpga chip logical combination device, automatically detect different classes of situation, in the different classes of situation of appearance, according to the processing demands of different grades, (Vehicle Controller system) sends request to master controller, after master controller is made corresponding control, issue the response code, dispose to show to report to the police.After the utility model sends request, in the time period that is provided with, can not get responding code, system will make emergent judgement and processing, and the instruction of processing has been divided into several levels: fall-back, parking emergency braking and high pressure break up three kinds.
Simultaneously, the utility model can be suitable for and the entire car controller Application of Linkage Control, also can be used as independently control unit realization monomer control and uses, and implementation is quite flexible.The utility model is during as a device that works alone, and reduction of speed instruction, cutoff command and high pressure differentiation instruction can be used as all independently that signal drives associative operation.When the utility model drove car load communication and filters from fpga chip, its reduction of speed instruction, cutoff command will be by communication output controls, and this moment, high pressure differentiation instruction must be as independently driving.
Description of drawings
Fig. 1 is a functional-block diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present utility model relates to a kind of safety guard of pure electric automobile, as shown in Figure 1, comprise control unit, normal inspection unit, electrical characteristics variation detecting unit and unexpected abnormality detecting unit, described control unit adopts fpga chip to constitute, and comprises the receiving element, judging unit and the processing unit that link to each other successively; Described normal inspection unit links to each other with described control unit by the first signal condition unit; Described electrical characteristics variation detecting unit links to each other with described control unit by secondary signal conditioning unit; Described unexpected abnormality detecting unit links to each other with described control unit by the 3rd signal condition unit.Wherein, described normal inspection unit is used to detect the conventional parameter of pure electric automobile; Described electrical characteristics variation detecting unit is used to detect the electrical characteristics variation parameter of pure electric automobile; Described unexpected abnormality detecting unit is used to detect pure electric automobile whether emergency case takes place; Described receiving element is used to receive the output signal of the described first signal condition unit, secondary signal conditioning unit and the 3rd signal condition unit; Described judging unit is judged according to the signal that receives; Described processing unit carries out reduction of speed according to judged result to pure electric automobile and controls, suddenly stops control or high pressure differentiation control.Described processing unit also links to each other with the vehicle control syetem of pure electric automobile.Its mesohigh differentiation control is exactly that the execution of high pressure (battery) by emergency switch disconnected, and makes it be divided into people's acceptable safety voltage.Because electronlmobil has high-tension feature, general work voltage is between 200V～650V, when accident takes place, so the high power that voltage produced must bring harm to the life property, can make the voltage between 60V～70V (or lower) of each equipment in the electronlmobil after carrying out this high pressure differentiation, thereby guarantee the life property safety.
Described normal inspection unit comprises independently battery voltage detection unit, energy content of battery detecting unit and battery temperature detecting unit.Described battery voltage detection unit is used to detect the cell pressure of pure electric automobile, after the receiving element in the control unit receives the cell pressure that records, judging unit compares cell pressure and the battery voltage value that sets in advance and the decision event grade, when if the cell pressure that records is lower than the battery voltage value that sets in advance, then processing unit is carried out reduction of speed control.Described energy content of battery detecting unit is used to detect the energy content of battery of pure electric automobile, after the receiving element in the control unit receives the energy content of battery that records, judging unit compares the energy content of battery and the energy content of battery that sets in advance and the decision event grade, when if the energy content of battery that records is lower than the energy content of battery that sets in advance, then processing unit is carried out reduction of speed control.Described battery temperature detecting unit is used to detect the battery temperature of pure electric automobile, after the receiving element in the control unit receives the battery temperature that records, judging unit compares battery temperature and the battery temperature value that sets in advance and the decision event grade, when if the battery temperature that records is higher than the battery temperature value that sets in advance, then processing unit is carried out reduction of speed control.Wherein, the reduction of speed control signal can be driven alone by processing unit and finish (being that direct output command is realized control), also can finish (i.e. array output instruction by the Communication Control word realizes control, and the information after this combination can be presented at state the read-out terminal equally) with the vehicle control syetem interlock.
