As shown in Figure 1, target vehicle 200 includes battery management system BMS, electric machine controller MCU, safety air sac controller
With entire car controller VCU, the battery management system BMS of target vehicle 200, electric machine controller MCU, safety air sac controller and whole
Vehicle controller VCU passes through CAN bus and is connected with test equipment, i.e. battery management system BMS, electric machine controller MCU, substitute
Capsule controller and entire car controller VCU pass through CAN bus respectively and are communicated with test equipment 300.
Based on the connection relationship of above-mentioned target vehicle 200 and test equipment 300, the vehicle collision of the embodiment of the present invention is proposed
Analog detection method.
Fig. 2 is the flow chart of the analog detection method of the vehicle collision of the embodiment of the present invention.As shown in Fig. 2, the present invention is real
Apply the analog detection method of the vehicle collision of example, comprising the following steps:
S101: simulated crash signal is generated.It should be noted that the air bag that simulated crash signal can issue for simulation
The signal of controller.In other words, when vehicle collides, safety air sac controller is based on collision and generates control signal, to be tested
Target vehicle can according to control signal execute collision when process flow.The embodiment of the present invention occurs in fact in order to avoid vehicle
Border collision causes practical vehicle to damage, and safety air sac controller is substituted in such a way that test equipment generates simulated crash signal and is generated
Signal is controlled, to enable the processing of target vehicle to be tested when executing vehicle collision after receiving simulated crash signal
Process, to realize the purpose of detection.In the embodiment of the present invention, test equipment can be equipped with the software of simulation softward for one,
The simulation softward can individually be installed on the terminal device, also may be mounted on vehicle, can pass through centainly with vehicle
Interface is communicated.Test equipment is also possible to an independent simulator.
Simulated crash signal: being sent to target vehicle to be tested by S102, so that target vehicle is believed according to simulated crash
Number, control executes process flow when vehicle collision.
After test equipment generates simulated crash signal, simulated crash signal can be sent to target vehicle.This hair
In bright embodiment, communication interface can be set between test equipment and target vehicle, be attached by the communication interface.It surveys
It can be carried out data transmission by communication interface between examination equipment and target vehicle.
Correspondingly, target vehicle is receiving simulated crash signal, can identify to the simulated crash signal, work as knowledge
When to be clipped to the simulated crash signal be the signal that vehicle is generated when colliding, processing when executing vehicle collision will be controlled
Process.
It should be noted that before being sent to target vehicle after test equipment generates simulated crash signal, it can also be first right
Simulated crash signal is detected, and in other words, whether the simulated crash signal that detection test equipment generates is normal, in test equipment
After simulated crash signal can be accurately generated, then to target vehicle transmission simulated crash signal, to prevent target vehicle from can not know
Detection caused by not is unqualified.
According to one embodiment of present invention, simulated crash signal is sent to after target vehicle to be tested, is also wrapped
Include: the status information for obtaining each vehicle assembly relevant to process flow judges the collision of target vehicle according to status information
Whether simulation test is qualified.
Specifically, target vehicle is after recognizing simulated crash signal, according to simulated crash signal respectively to battery management
System BMS, electric machine controller MCU and entire car controller VCU send crash protection signal.Wherein, battery management system BMS is received
Crash protection signal, and cut-off signal is generated according to crash protection signal and is sent to relay, with disconnect it is main just with it is main it is negative after
Electric appliance, electric machine controller MCU Receiving collision protects signal, and carries out discharge operation to busbar voltage according to crash protection signal,
Entire car controller VCU Receiving collision protects signal, and sends high pressure open command according to crash protection signal.
Due to needing to meet after requiring vehicle collision in national standard GB/T 31498-2015 " safety requirements after electric automobile collision "
Electrocution-proof protection requirement, that is, high pressure has to be off after collision, and after collision in 5s-60s, it is (straight that high-voltage system voltage should be less than 60V
Stream).Therefore, the data that test equipment can be fed back by checking CAN bus, judge after test equipment sends simulated crash signal
In preset time, whether master is just disconnected with the negative relay of master, and busbar voltage whether is reduced to predeterminated voltage hereinafter, and bus electricity
Whether stream is 0, if it is main just with the negative relay of master disconnects, busbar voltage is being reduced to predeterminated voltage hereinafter, and bus current is 0,
Then think that target vehicle collision detection is qualified.Specifically, target vehicle can also have malfunction coefficient instrument, to touch in vehicle
Fault message is sent to malfunction coefficient instrument when hitting, and fault message is shown by malfunction coefficient instrument.
The analog detection method of the embodiment of the present invention as a result, can send simulated crash signal by test equipment, to replace
Collision alarm is sent for safety air sac controller, thus when carrying out collision detection to vehicle, without carrying out actual collision
Corresponding collision detection is carried out to vehicle, vehicle damages caused by reducing because of detection process, and it is energy saving, reduce production cost.
It should be understood that during carrying out impact simulation test to vehicle, since analog test signal is by surveying
It tries what equipment generated, in order to avoid safety air sac controller false triggering generates actual collision alarm, needs to implement in the present invention
Failure state is set by safety air sac controller in example, is set so that it is guaranteed that vehicle is only identified when carrying out collision detection by test
The simulated crash signal that preparation is sent, avoid vehicle cause to detect because of wrong identification collision alarm it is unqualified.
Therefore, on the basis of above-described embodiment, Fig. 3 is the mould of another vehicle collision provided in an embodiment of the present invention
The flow chart of quasi- test method.Before generating simulated crash signal, as shown in figure 3, the simulation test side of the vehicle collision
Method, further comprising the steps of:
S301: whether the safety air sac controller for detecting target vehicle is in failure state.
Wherein, test equipment can read the substitute of target vehicle by CAN bus before generating simulated crash signal
The status signal of capsule controller, and determine according to the status signal state of air bag.
S302: if safety air sac controller is not in failure state, indication signal is sent to target vehicle, so that target
Vehicle controls safety air sac controller according to indication signal and is in failure state.
Specifically, judging whether air bag is in failure after test equipment obtains air bag status signal
State further generates simulated crash signal, if air bag is not in failure if air bag is in failure state
State then generates indication signal according to the current state of air bag, for example, a character, test equipment will by CAN bus
Character signal is sent to safety air sac controller, so that safety air sac controller itself will be placed in failure shape according to character signal
State, for another example, the also capable of emitting prompting message of test equipment, so that operator can manually control air bag according to prompting message
Controller is in failure state.It wherein, can when control safety air sac controller, which is manually operated, in operator is in failure state
Air bag is set to be in failure state by way of pulling out safety air sac controller connector or low pressure insurance.
It should be noted that test equipment can increase node to simulate offline air bag control in virtual sending module
Device node processed.
Thereby, it is possible to guarantee that simulated crash signal identification can be the signal of safety air sac controller by target vehicle, with
Further execute process after colliding.
In the embodiment of the present invention, communicated between test equipment and target vehicle by CAN bus, therefore, test equipment can
Analog test signal is sent to target vehicle in the form of through message.Target vehicle is needed to receiving for safety
Message is verified.Such as the variation of message life signal periodic law and/or the verification of message content.Therefore, it is touched in generation simulation
While hitting signal, it is also necessary to simulate the message life signal of outgoing packet and/or the check code of message.Fig. 4 is that the present invention is implemented
The flow chart of the analog detection method for another vehicle collision that example provides.As shown in figure 4, the simulation test of the vehicle collision
Method, further comprising the steps of:
S401: while generating simulated crash signal, the message life signal of target vehicle is generated.
Specifically, while generating simulated crash signal, the message life signal of target vehicle is generated, by simulated crash
Signal and message life signal synchronize be sent to target vehicle.
Wherein, message life signal can be written as the period add the function of 1 and 0-255 circulation change simulate occur life letter
Number, in other words, message life signal occupies a byte, range 0-255, with+1 rule variation of period, wherein when message life
It is sent since 0 again when signal reaches 255.Specifically, target vehicle after receiving message life signal, judges current report
Whether literary life signal and the previous message life signal received meet periodic regularity, if it is, determining current message
Life signal is effective, if it is not, then determining that current message life signal is invalid.Wherein, meeting periodic regularity is current message
Life signal value is previous message life signal value+1.
It should be understood that the effect of message life signal is that characterization CAN bus node entire car controller VCU does not occur
Failure etc., it is reliable for so that other nodes is apparent from the CAN bus message received.If message life signal adds every time
1, it may be considered that the node works normally, if it is not, then the message of the node is insecure.Therefore, when message life
When signal meets periodic regularity, target vehicle judges that message life signal is reliable, and then executes simulated crash signal.
S402: while generating message life signal, message checking code is generated.
Specifically, while generating message life signal, check code is generated for message life signal, check code is carried
In message life signal.
Message checking code can also occupy a byte, range 0-255, and specific value is other byte numbers in same message
The value that value negates after being added, if more than 0xFF after the addition of other byte values, then remaining numerical value negates i.e. after removing highest byte
For the value of check bit.When writing program, message ID is 0x110 as where collision alarm, then first to uncertain in a communications protocol
The message assignment (such as 0x210) of adopted ID, message content remove check bit after it is completely the same with the message content of 0x110, according to school
The create-rule for testing position writes Program Generating verification bit value, and byte of the assignment into 0x110 message where check bit then issues
0x110 message be the message that can correctly identify.
It should be understood that the effect of message checking code is to prevent input error.Therefore, when message checking code can be by just
Really when identification, target vehicle executes simulated crash signal.
S403: message checking code and message life signal are carried and sent in the message.Specifically program realization is patrolled
It collects as follows:
That is, when target vehicle receives test equipment transmission simulated crash signal, it is also necessary to judge message life
Whether signal and check code meet communication criterion, and are all satisfied communication criterion in message life signal and check code, and receive
When to simulated crash signal, target vehicle identifies that simulated crash signal is effective, and is controlled according to simulated crash signal and execute vehicle
Process flow when collision.
It should be understood that verifying message can also be carried out separately through message life signal, it can also be separately through report
The check code of text carries out verifying message.
The analog detection method of the vehicle collision of the embodiment of the present invention as a result, can generate simulation by test equipment and touch
Signal is hit to avoid actual collision bring economic loss and insecurity, it can also enough passing through message life signal and school
Testing code makes simulated crash signal further satisfaction enterprise bus specification, guarantees that simulated crash signal can be executed correctly.
It should also be noted that, since the difficult point for simulating transmission collision alarm by test equipment is, each vehicle enterprise
There is self-ordained bus communication specification, therefore, it is necessary to determine that target vehicle is used before generating analog test signal
Bus communication specification.Obtain the attribute information of target vehicle, such as mark of affiliated enterprise, model etc..Further, according to
The attribute information of target vehicle obtains communication protocol used by the communication bus of target vehicle, according to communication protocol, generates mould
Quasi- collision alarm, message life signal and message checking code.
It should be noted that simulated crash signal to be sent to target vehicle to be tested, comprising: obtain target vehicle
The baud rate of communication bus；According to baud rate, simulated crash signal is sent to target vehicle, to guarantee that target vehicle can connect
It receives and identifies simulated crash signal.
Wherein, the baud rate of communication bus can be inquired by the attribute information of target vehicle, such as the mark of the enterprise
Knowledge, model etc..
As shown in figure 5, a specific embodiment according to the present invention, the analog detection method of vehicle collision, including it is following
Step:
S201: test equipment is connected with target vehicle by CAN bus.
S202: whether detection safety air sac controller is offline, and substitute is controlled when safety air sac controller is not offline
