When, whether harness controls box by built-in MCU (Micro control unit) micro-control unit, detect and be connected on harness
ECU electronic control unit, if so, 102 are thened follow the steps, if it is not, thening follow the steps 103.
Specifically, the deterministic process whether MCU connects ECU is as follows: MCU passes through specific in the connector that connect with ECU
The level state of terminal detects whether harness is connected with ECU electronic control unit, such as when MCU detects the end K06 in connector
When the level of son is high level, show not connect ECU, thens follow the steps 104, and when the level of K06 terminal is low level,
Show to have connected ECU, thens follow the steps 102.
102, the type of the ECU is detected, and receives the ECU model inputted by the ECU selection key；
When MCU detects harness control box by connector and ECU successful connection, then the class of the ECU is further detected
Type, and the ECU model that user inputs is received by ECU selection key.
Specifically, ECU has different type and model, and for the ECU of different model, there is the different modes of connection,
Table 1 is the ECU and the mode of connection of different model.
Further, MCU can by the terminal signals of the positive and negative anodes in the connector that is connect with ECU, to the type of ECU into
Row judgement, such as when the sharp power of ECU model CV44/vm/, c54, c81, EDC17 or wise13, K01, K03 or K05 terminal are
Positive pole, K02, K04 or K06 terminal are power cathode, and as ECU model wise12A or c63, then it is K04 or K06
For positive pole, and K01 or K02 is power cathode, therefore MCU can judge ECU's according to the anode and cathode terminals in connector
Then type receives the ECU model that user is inputted by ECU selection key, it should be noted that step 102 is first to ECU type
Just judgement is carried out, when passing through the ECU model of ECU selection key input error to prevent user, by the switching signal of mistake to ECU
It powers on, is scrapped so as to cause ECU, therefore step 102 can be by the first identification to ECU type, to enhance the safety detected to ECU
Property.
Table 1
103, according to the ECU model, the driving circuit and the switch arrays are controlled, so that corresponding communication signal
And switching signal is in the conductive state；
When MCU receives the ECU model of input, MCU controls driving circuit and switching signal, so that with ECU model pair
The communication signal and switching signal answered are in the conductive state.
Specifically, as described in Table 1, when MCU detects the ECU model c63 of input, then passing through the K71 in connector
Terminal is powered on to ECU, i.e., so that switching signal is in the conductive state, while by k66 the and k65 terminal in connector, so that
CAN1 signal in communication signal is in the conductive state.
104, other processes are executed.
When in step 101 MCU be not detected be connected with ECU when, then execute other processes, such as continue to ECU connection letter
It number is detected, or enters program of having a rest, be not particularly limited herein.
In the embodiment of the present application, the multiple harness for connecting multiple and different ECU types are normalized, and by being connect with harness
Harness control box in MCU detect whether the harness is connected with ECU, and when harness is connected with ECU, further to ECU's
Type is judged, the model of ECU is then inputted by ECU selection key, controls driving circuit and switch by the model of ECU
Signal, so that communication restricting the number corresponding with ECU and switching signal are in the conductive state, because using single line in the present embodiment
Connection of the Shu Shixian to multiple and different type ECU, and harness control box can also realize the automatic detection to ECU type, from
And it improves and multiple ECU intelligence connecting and portability.
Based on Fig. 1 the embodiment described, before step 101 and after step 103, it is also necessary to in harness control box
MCU execute following steps, referring specifically to Fig. 3, in the embodiment of the present application more ECU harness connection methods another implementation
Example, comprising:
301, the MCU is powered on by the power adapter, so that the MCU controls the switch arrays,
Make all switching signals all in off-state；
It is easily understood that before whether MCU detection ECU connects, it is also necessary to by main power source and power adapter to MCU
It is powered on, to complete the initialization to MCU, the process of the initialization of specific MCU is the MCU control when powering on to MCU
Switch arrays processed, so that all switching signals are all in off-state, to prevent when switching signal is connected, so as to ECU
Carry out it is hot-swappable, and cause to ECU stealth damage.
302, MCU detects whether harness is connected with ECU electronic control unit, if so, 303 are thened follow the steps, if it is not, then holding
Row step 306；
303, the type of the ECU is detected, and receives the ECU model inputted by the ECU selection key；
It should be noted that step 302 in the present embodiment is to 303 and the step 101 in embodiment described in Fig. 1 to 102
Similar, details are not described herein again.
304, judge whether the ECU model matches with the ECU type, if so, 305 are thened follow the steps, if it is not, then holding
Row step 308；
ECU mistake is powered in order to prevent, causes to damage to ECU, when MCU receive user by ECU selection key it is defeated
When the ECU model entered, whether the ECU model that MCU judgement receives matches with the ECU type detected, if so, thening follow the steps
305, if it is not, thening follow the steps 308.
Specifically, as shown in table 1, when MCU is belonged to by the ECU of the anode and cathode terminals judgement access in connector
When wise12A or c63, and the ECU model c81 that user is inputted by ECU selection key, then not for ECU model and ECU type
Matching, thens follow the steps 308, and as the ECU model c63 that user inputs by ECU selection key, then for ECU model and
ECU type matching, thens follow the steps 305.
305, according to the ECU model, the driving circuit and the switch arrays are controlled, so that corresponding communication signal
And switching signal is in the conductive state, and gives the first prompt by indicator light；
When MCU controls driving circuit and switch arrays, so that corresponding communication signal and switching signal are all in conducting shape
When state, the first prompt can also be given by indicator light, if indicator light shows green, to identify communication signal corresponding with ECU
And switching signal is all on state.
306, other processes are executed；
It should be noted that step 306 is similar with the step 104 in embodiment described in Fig. 1 in the present embodiment, herein no longer
It repeats.
307, when MCU monitors that the ECU is disconnected, the MCU controls the switch arrays, so that all switches
Signal is all in off-state；
Specifically, when completing the detection or firmware upgrade to ECU, if MCU monitors that ECU is disconnected, MCU control
Switch arrays processed so that all switching signals are all in off-state, and are detecting that harness passes through connector and connect again
When ECU, step 301 is repeated to 307.
It is easily understood that when MCU monitors that ECU is disconnected, control switch array, so that all switching signals are all
It is in an off state, can prevent when switching signal is charged, it is hot-swappable to the ECU progress for executing testing process again, with right
ECU causes stealthy breaking-up.
308, the second prompt is given by indicator light.
When ECU model and ECU type mismatch, MCU can control indicator light and give the second prompt, to remind user defeated
Enter error, if indicator light can be displayed in red, to give user's prompt.
In the present embodiment, MCU execution is being powered on and when MCU monitors that ECU is disconnected, all control switch array, made
All switching signals are obtained all in off-state, thereby may be ensured that ECU in connection wiring harness, harness is all in uncharged shape
State prevents ECU when hot-swappable, the stealth caused by ECU damages.
