Description of the drawings
Fig. 1 is the inside composed structure schematic diagram of gas pedal.
Specific implementation mode
The present invention will be further described in detail below in conjunction with the accompanying drawings.
In new energy vehicle electronic control, accelerator pedal signal is most important, is the core in Vehicle Electronic Control strategy
It feels at ease and protects component.In new energy vehicle system, gas pedal installation space is sufficient, and the integrated multifunction in pedal may be implemented
Electronic detection unit.
As shown in Figure 1, for comprising modules, which includes pedal body, and pedal body is exactly for trampling
Pedal machines mechanism, this part-structure is all gas pedals most basic mechanical structure for including, belongs to existing
Technology does not repeat here.
The gas pedal further includes changing sensor and control unit, changing sensor be used for the mechanical deformation of pedal into
Row detection, and export corresponding signal.Changing sensor output connects the control unit, and control unit includes mainly three parts：
Analog signals generation module, digital signal generation module and on-off model generation module, analog signals generation module are used
In output two-way throttle analog quantity voltage signal, digital signal generation module is opened for exporting pedal aperture digital signal all the way
Pass amount signal generator module is for exporting two-way Oil Switch amount signal.Such as：The changing sensor is slide rheostat, simulation
Amount signal generator module be voltage transformation module, slide rheostat detect pedal deformation degree, voltage transformation module according to
The degree of deformation corresponds to output voltage values.Digital signal generation module accordingly exports characterization according to the degree of pedal machines deformation and steps on
The digital signal of plate aperture.Such as：The changing sensor is obliquity sensor, and digital signal generation module is digit chip, is inclined
Angle transducer detects the inclination angle of pedal, and digit chip is detected according to inclination angle and corresponds to output aperture digital signal.
In short, the signal that the deformation signal of sensor output exports after being handled by different processing modules is different
's.Moreover, digital signal generation module and analog signals generation module are isolated, i.e. aperture digital signal and analog quantity
Between voltage signal independently of each other, mutually it is independent of each other and interferes respective information；So even if the letter of one of module output
Number there is failure, the signal of another module output is not affected by faults.
Sensor can export two-way deformation signal, the sub signal P2 of pedal deformation main signal P1 and pedal deformation, wherein
Pedal deformation main signal P1 is directly proportional to pedal deformation, and sub signal P2 is inversely proportional with pedal deformation, such as when sensor is sliding
When rheostat, the two paths of signals of output is：Voltage signal between slider and one end of slide rheostat and slider
Voltage signal between the other end of slide rheostat, when the voltage between slider and one end of slide rheostat becomes larger
When, the voltage between the contact and the other end of slide rheostat corresponding will become smaller.Pedal deformation main signal P1 is converted into electricity
Signal S1, the sub signal P2 of pedal deformation is pressed to be converted into voltage signal S2.
In addition, two on-off model generation modules generate gas pedal Oil Switch amount signal be high potential 1 or
Person's low potential 0.Whether on-off model generation module selects existing switching value generation device, trampled and corresponded to according to pedal
Generate two different electric potential signals.When pedal in the initial state, i.e., when not trampled, export a switching value；As long as stepping on
Plate is trampled, and regardless of degree, at this moment, exports another switching value.Since the gas pedal includes two on-off models
Generation module, first on-off model generation module generate switching value K1, and second on-off model generation module generation is opened
K2 is measured in pass, and K1 is corresponding with P1, and K2 is corresponding with P2.
Since the entire car controller in vehicle controls vehicle when driving in the signal exported according to gas pedal, only need to receive
To a throttle output signal, so, the two analog quantity voltage signal generator modules correspond to the two-way throttle mould generated
Analog quantity voltage signal S1 and S2 redundancy is arranged, as long as entire car controller receives any one signal in S1 and S2 and can carry out
Vehicle traction controls；Similarly, also redundancy is arranged Oil Switch amount the signal K1 and K2 that two on-off model generation modules generate.
By the processing of signal processing module, make the range of voltage values of two-way throttle analog quantity voltage signal S1 and S2 just
It is V1~V2 in the case of often, and the sum of voltage value for setting the two-way throttle analog quantity voltage signal is constant always, is V1+
V2；Wherein, V1 and V2 is setting voltage threshold.As a specific embodiment, in the present embodiment, V1 0.5V, V2 are
4.5V, i.e. voltage signal S1 are 0.5V, and voltage signal S2 is 4.5V, also, S1+S2 is always 5V.The power supply of S1 and S2 is whole
Range is 0-5V, effective range 0.5-4.5V, the corresponding pedal aperture 0-100% of the effective range.When pedal is initial
When state, S1 0.5V, S2 4.5V；When stepping on pedal, pedal ensures that S1 sampling linears increase, S2 in deformation process
Sampling linear reduces, and in change procedure, keeps S1's and S2 and is worth constant, i.e. S1+S2=5V.As pedal aperture be 50% when,
S1=S2=2.5V.
In the initial state, K1 is vacant state (high potential 1), and K2 is low switch state (with earth signal short circuit, low potential
0)；When pedal is trampled, K1 is changed into low switch state, and K2 is vacant state.
The range of pedal opening signal is 0-250, corresponds to aperture 0-100% respectively, and rate is 0.4 to aperture respectively, then, greatly
In 250 opening value be invalid value.Pedal aperture digital signal is corresponding with P1, with the variation of deformation main signal P1 to strain
Change.
In addition, in the present embodiment, when the signal of control unit output uploads, data message uses 8 byte of J1939 agreements
Format is uploaded, wherein the first byte is pedal opening signal, and the second byte is throttle mains value S1, third byte oil
Door secondary voltage value S2, the expression IS Idle Switch amount K1 of nybble 0-3, the expression IS Idle Switch of nybble 4-7 amount K2, the 5th
Byte is voltage signal effective marker, and the 6th byte is gas pedal life cycle signal, and the 7th byte indicates for error code, uses
In to bus information failure state, the 8th byte is reserve bytes.When wherein the 5th byte is invalid flag, CAN is preferentially selected
Message pedal opening signal is controlled, and table 1 gives CAN communication message protocol.
Table 1
Entire car controller samples major-minor voltage value S1, S2, and sampling K1, K2 correspond to switching magnitude, while receiving accelerator open degree
Digital signal, major-minor voltage value and fault message etc. are transmitted, vehicle control using the CAN message signal of above-mentioned 8 byte format
Device processed carries out policy control judgement, decides accelerator open degree value size, to judge that driver driving is intended to, is finally opened with determining throttle
Angle value carries out vehicle driving moment output, carries out vehicle energy hole.
In the initial state, driver does not tread on an accelerator pedal, and Oil Switch amount, voltage signal and aperture digital signal are equal
In default conditions, i.e. pedal voltage signal S1 is 0.5V, S2 4.5V.Switching signal K1 is vacant state, and K2 is low switch
State.8 byte of CAN message sends 0x00 0x19 0xE1 0x10 0x01 0x00 0x00 0xFF.
When aperture effective status, driver tramples gas pedal, pedal voltage signal and switching value hair according to oneself wish
Changing.Pedal voltage signal S1 and S2 exports for analog voltage, and S1 and S2 and value remain constant, is 5V.Switching signal
K1 becomes low switch state, and K2 becomes vacant state.Accelerator open degree digital signal is corresponding with pedal aperture.Such as in pedal aperture
When being 50%, S1=S2=2.5V, 8 byte of CAN message sends 0x7D 0x7D 0x7D 0x01 0x01 0x00 0x00
0xFF。
When S1 exceptions or S2 exceptions, i.e. S1 is less than 0.5V or is less than 0.5V more than 4.5V or S2 or is more than 4.5V
When, gas pedal voltage signal is invalid signals, passes through CAN bus reporting fault code；At this time just such as pedal aperture digital signal
Often, then can using in CAN message pedal aperture digital signal as whole vehicle control signal.
When the analog voltage signal for having analog quantity voltage signal normally to export, but exporting is mismatched with on-off model,
Pedal aperture digital signal in CAN message should be used to control signal, and reporting fault code 0x02, and the 5th as the output of pedal
Byte sets invalid state 0x00；Here mismatch refers to：Under normal circumstances, when pedal is not trampled, S1 V1, K1 are height
Current potential, S2 V2, K2 are low potential；If at this time：S1 is V1, and K1 is but low potential, and S2 V2, K2 are but high potential, or
S1 is V2, and K1 is but high potential, and S2 V1, K2 are but low potential, show that analog voltage signal is mismatched with on-off model.
As S1+S2 ≠ 5V, pedal voltage S1 and S2 are invalid value, reporting fault code 0x01, and the 5th byte sets nothing
Effect state 0x00；If Oil Switch amount signal K1 and K2 are normal at this time, it is possible to using pedal aperture digital signal conduct
The throttle control signal of gas pedal output.
When analog quantity voltage signal S1 and S2 and pedal aperture digital signal mismatch, and the two-way throttle analog quantity voltage
The range of voltage values of signal is V1~V2, when the sum of voltage value is 5V, the oil that takes S1 or S2 to be exported as the gas pedal
Gate control signal.Since analog quantity voltage signal and pedal aperture digital signal are under normal circumstances there is certain relationship,
Such as analog quantity voltage signal S1 and the proportional relationship of pedal aperture digital signal, such as when V1 is 0.5V, digital aperture letter
Number be 0, as V1 increases, digital signal can increase accordingly, when V1 be 4.5V when, aperture 100%, digital signal 250,
At this moment normal situation.But when if there is abnormal conditions, for example, V1 be 0.5V when, digital signal be 0, but other
Numerical value, at this moment just illustrate that analog quantity voltage signal and pedal aperture digital signal mismatch, so, as long as analog quantity electricity in a word
When pressing the existing proportional relation between signal and pedal aperture digital signal abnormal, you can show that the two mismatches.
When pedal aperture digital signal and Oil Switch amount signal K1 and K2 are mismatched, vehicle is catastrophe failure at this time,
The throttle control signal of control gas pedal output is forced to 0；Here mismatch refers to：Under normal circumstances, pedal not by
When trampling, it is high potential that the output of pedal aperture digital signal, which is zero, K1, and K2 is low potential；When pedal is trampled, pedal aperture number
Word signal exports corresponding opening value, and K1 is low potential, and K2 is high potential；If at this time：Pedal aperture digital signal exports
Zero, K1 are low potential, and K2 is high potential；Alternatively, pedal aperture digital signal exports corresponding opening value, K1 is high potential, K2
For low potential, above-mentioned two situations show that pedal aperture digital signal is mismatched with Oil Switch amount signal K1 and K2.
CAN message life cycle is per second under normal circumstances can increase by 1；When CAN message life cycle stops increasing, table
Bright life cycle signal mistake, is determined as CAN data faults, and tactful protection should be carried out by entire car controller.Such as：When CAN is reported
When literary life cycle signal mistake, and when two-way throttle analog quantity voltage signal and normal two-way Oil Switch amount signal, take
Throttle control signal one of in the voltage value of the two-way throttle analog quantity voltage signal as gas pedal output.
In addition, for the explanation of above-mentioned several fault conditions, table 2 has been illustrated on the basis of above-mentioned several failures
Several specific failures and corresponding processing strategy, wherein first word of text section aperture is collected pedal aperture number
Word signal.
Table 2
In addition, the opening amount signal of the first byte of CAN message, i.e. pedal aperture digital signal have calibrating function.Pass through CAN
It communicates dedicated calibration ID and accelerator opening amount signal calibration is carried out to throttle original state and largest deformation state.When non-pedal,
Accelerator open degree initial value is demarcated by demarcating ID, is demarcated as 0%；Pedal is floored, and is demarcated to accelerator open degree value,
It is demarcated as 100%.If pedal voltage drifts about, when non-pedal, pedal output voltage S1 or S2 voltage deviation 0.5V is larger,
0% accelerator opening amount signal calibration can be carried out to pedal original state by CAN communication calibrating function.After calibration, CAN communication
The accelerator opening amount signal of first byte output is 0%；When stepping on pedal, accelerator opening amount signal according to the voltage of initial alignment into
Row linear convergent rate accelerator open degree.Calibration process：Calibration software sends calibration CAN message, gas pedal feedback calibration response message.
8 bytes of message are demarcated, the first byte is calibration state, and the second byte to the 5th byte is calibration key, and the 6th byte is mark
Fixed accelerator open degree desired value, the 7th byte and eight bytes are retention；Response message is 8 bytes, and the first byte is calibration
State, the second byte to the 5th byte are calibration seed, and the 6th byte is the accelerator open degree value of feedback of calibration, and the 7th byte is mark
The throttle mains value S1 that timing is carved, the 8th byte are to demarcate the throttle secondary voltage value S2 at moment.
In above-described embodiment, gas pedal includes two on-off model generation modules, and each module exports a switch
Amount, as other embodiments, as shown in Figure 1, the gas pedal can also only include an on-off model generation module, it should
Generation module is equivalent to a single-pole double-throw switch (SPDT), and when switch gets to 3 end, switching value K2 is low potential, and K1 is high potential；When
When switch gets to 1 end, switching value K2 is high potential, and K1 is low potential, and the switching value that single-pole double-throw switch (SPDT) is similar to by this is believed
