Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is refer to, a kind of motor rotation blockage fault judgment method is the embodiment of the invention provides, comprised the following steps：
Step 001, when the output torque for detecting motor reaches the max. output torque of setting, starts timing.
Step 002, however, it is determined that during the first setting duration is reached, the output torque of motor is continuously timing duration
Max. output torque, then in timing during a length of first setting duration, the output torque of controlled motor is reduced to target output and turns round
Square, and reclocking.I.e. when the time that motor runs under max. output torque equals or exceeds the first setting duration, control
The output torque of motor is reduced to target output torque, and restarts timing.
Step 003, however, it is determined that the timing duration after reclocking during the second setting duration is reached, motor it is defeated
Go out moment of torsion and be continuously target output torque, then determine that motor is deposited during a length of second setting duration in the timing after reclocking
In stall failure, and report stall fault message.I.e. after reclocking, the time that motor runs under target output torque is equal to
Or during more than the second setting duration, determine that motor has stall failure, and stall fault message is reported, complete motor rotation blockage failure
Judgement and report.
Wherein, under target output torque, larger moment of torsion can be still exported, can be continued in the second setting duration
Judge motor whether stall.Be can be seen that since motor runs under max. output torque, to stall by above-mentioned determination methods
Failure determines to report, and the used time is the first setting duration and the second setting duration sum altogether, because motor sets duration second
Interior operation moment of torsion is target output torque, less than max. output torque, the IGBT switches in electric machine controller to produce with most
The time that the same energy loss of big output torque spends increases, i.e., under equal conditions, the first setting duration and second sets
Duration sum is more long than being called time on determination stall of the prior art, and the frequency that stall failure is reported is reduced, what stall was reported
Authenticity method also compared with before is good；At the same time, because second sets the output torque that motor is reduced in duration, so that electric
In machine controller the energy loss of IGBT also compared with equal stall time under it is small, as long as down slightly output torque, just
The energy loss of IGBT switches can significantly be reduced.So as to reduce the IGBT to electric machine controller under motor rotation blockage operating mode
Excess temperature damage, while reducing the possibility of stall fault misdescription.
Used as optimization, in the present embodiment, the difference between target output torque and max. output torque is less than or equal to
10N.m, i.e. target output torque are smaller than max. output torque, and difference is no more than 10N.m.It can be seen that, target output torque is only needed
Down slightly can equally export larger moment of torsion, can be used for judge motor whether stall.Certainly, according to vehicle
The carrying calorific capacity of actual condition and IGBT come set the first setting duration, the size of target output torque and correspondence target
The size of the second setting duration of output torque setting.Preferably, when the first setting duration is slightly smaller than of the prior art default
Between, and the first setting duration and the second setting duration sum are more than Preset Time of the prior art.
As shown in Fig. 2 in the present embodiment, motor rotation blockage fault judgment method is optimized, in step 002,
During timing during a length of first setting duration, except the output torque of controlled motor is down to target output torque, also control simultaneously
IGBT reduction switching tube frequencies.Reducing the switching tube frequency of IGBT can further reduce the energy ezpenditure of IGBT switches, so that
Further reduce under motor rotation blockage operating mode and the excess temperature of the IGBT of electric machine controller is damaged.It is of course also possible to only reduce motor
Output torque.And carry out frequency reducing simultaneously to subtract torsion can be also to ensure motor on the premise of response vehicle demand as accurate as possible
System normal communication.
Used as optimization, in the present embodiment, control IGBT reductions switching tube frequency is specially：Control the switching tube of IGBT frequently
Rate is down to 5kHZ by 10kHZ.I.e. the common working frequency of IGBT switching tubes is 10kHZ, and the working frequency after reduction is 5kHZ.
Reducing the switching tube frequency of IGBT can extend the cycle of electric machine controller communication packet, play communication function, the switching tube of IGBT
Frequency can not be very low, too low to be unable to accurate acquisition system mode, therefore, under conditions of normal communication is met, reduce
Working frequency can reduce the power consumption of IGBT.
As shown in figure 3, in the present embodiment, motor rotation blockage fault judgment method is further optimized, in step 002,
When the output torque for detecting motor reaches the max. output torque of setting, start timing, however, it is determined that motor continues in maximum
When the timing duration run under output torque is less than the first setting duration, it is determined that motor does not exist stall failure, controlled motor
Normal operation, vehicle normally runs.
Further, in the present embodiment, in step 003, when the output torque of controlled motor is reduced to target output
After moment of torsion, and reclocking, however, it is determined that motor continues the timing duration run under target output torque less than the second setting
Duration, and motor under less than target output torque when running, it is determined that motor does not exist stall failure, and controlled motor is being worked as
Continued to run with preceding moment of torsion, perform the torque command of gas pedal.
Further, in step 003, it is determined that the lasting timing duration run under target output torque of motor is small
Duration is set in second, and motor under less than target output torque when running, it is determined that motor does not exist after stall failure,
Except controlled motor is continued to run with current torque, the torque command of gas pedal is performed, while also controlling the switch of IGBT
Pipe frequency upgrading is promoted to 10kHZ to original frequency by 5kHZ.Normally sampled communication so as to meet electric machine controller,.
As shown in figure 4, in order to preferably motor rotation blockage failure is judged and reported, in the present embodiment, in step
In 002, when it is determined that the lasting timing duration run under max. output torque of motor determines motor not less than the first setting duration
When there is stall failure, the first flag is set, the first flag is indicated without stall failure, and stall failure is not reported.By setting
The first flag is put so that entire car controller quickly reads information, action of going forward side by side makees corresponding.First flag can be 0.
Similarly, in embodiment, in step 003, when it is determined that motor continues the meter run under target output torque
Shi Shichang runs less than the second setting duration, and motor less than under target output torque, determines that motor does not exist stall failure
When, the second flag is set, the second flag represents one-level stall failure, does not report stall failure, the second flag to be
1；
When it is determined that motor has stall failure, the 3rd flag is set, the 3rd flag represents two grades of stall failures, on
Report stall failure, the 3rd flag can be 2.
Different flags are set for different judged results, so that entire car controller is carried out according to different flags
The judgement and display of motor rotation blockage failure.
As shown in figure 4, in the present embodiment, the specific work process of motor rotation blockage fault judgment method is：
Step 001, when the output torque for detecting motor reaches the max. output torque of setting, starts timing.
Step 002, when determining that motor continues the timing duration of the operation under max. output torque less than the first setting duration,
Then determine that motor does not exist stall failure, sets the first flag, do not report stall failure, controlled motor normally to run, vehicle

Conversely, however, it is determined that during the first setting duration is reached, the output torque of motor is continuously most timing duration
Big output torque, then in timing during a length of first setting duration, the output torque of controlled motor is reduced to target output torque,
Control IGBT reduction switching tube frequencies, and reclocking.
Step 003, however, it is determined that motor continues the timing duration run under target output torque less than the second setting duration,
And motor under less than target output torque when running, it is determined that motor does not exist stall failure, the second flag, second are set
Flag represents one-level stall failure, but does not report stall failure, and controlled motor is continued to run with current torque, performs
The torque command of gas pedal, controls the switching tube frequency upgrading of IGBT to original frequency；
Conversely, however, it is determined that the timing duration after reclocking during the second setting duration is reached, the output of motor
