As optimization, in the present embodiment, control IGBT reduces switching tube frequency specifically: controls the switching tube frequency of IGBT
Rate is down to 5kHZ by 10kHZ.I.e. the common working frequency of IGBT switching tube is 10kHZ, and the working frequency after reducing is 5kHZ.
The switching tube frequency for reducing IGBT can extend the period of electric machine controller communication packet, play communication function, the switching tube of IGBT
Frequency cannot be very low, too low acquisition system state therefore under conditions of meeting normal communication, accurately cannot to 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 advanced 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 stall failure is not present in motor, controls motor
It operates normally, vehicle operates normally.
Further, in the present embodiment, in step 003, when the output torque of control motor is reduced to target to export
Torque, and after 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 being less than target output torque when running, it is determined that stall failure is not present in motor, and controls motor and working as
It is continued to run under preceding torque, executes the torque command of gas pedal.
Further, in step 003, determining that it is small that motor continues the timing duration run under target output torque
Duration being set in second, and motor under being less than target output torque when running, it is determined that motor is not present after stall failure,
In addition to control motor continues to run under current torque, the torque command of gas pedal is executed, while also controlling the switch of IGBT
Pipe frequency upgrading is promoted to 10kHZ by 5kHZ to original frequency.Communication is normally sampled to meet electric machine controller,.
As shown in figure 4, in order to which preferably motor rotation blockage failure is judged and is reported, in the present embodiment, in step
In 002, when determining that motor continues the timing duration that runs under max. output torque less than the first setting duration, determine motor not
There are when stall failure, first identifier position is set, first identifier position indicates no stall failure, do not report stall failure.By setting
First identifier position is set so that entire car controller quickly reads information, action of going forward side by side is made corresponding.First identifier position can be 0.
Similarly, in embodiment, in step 003, when the meter for determining that motor is persistently run under target output torque
Shi Shichang is less than the second setting duration, and motor is run in the case where being less than target output torque, and determining motor, there is no stall failures
When, second identifier position is set, second identifier position indicates level-one stall failure, do not report stall failure, second identifier position can be
1；
Second level stall failure is indicated there are third marker, third marker when stall failure, is set when determining motor, on
Stall failure is reported, third marker can be 2.
Different markers is set for different judging results, so that entire car controller is carried out according to different markers

Step 001, when the output torque for detecting motor reaches the max. output torque of setting, start timing.
Step 002, when determining that motor continues the timing duration run under max. output torque less than the first setting duration,
It then determines that stall failure is not present in motor, sets first identifier position, does not report stall failure, control motor operates normally, vehicle
It operates normally；
On the contrary, however, it is determined that during reaching the first setting duration, the output torque of motor is continuously most timing duration
Big output torque, then when timing duration is the first setting duration, the output torque for controlling motor is reduced to target output torque,
Controlling IGBT reduces switching tube frequency, and reclocking.
Step 003, however, it is determined that motor continues the timing duration run under target output torque and sets duration less than second,
And motor be less than target output torque under run when, it is determined that motor be not present stall failure, set second identifier position, second
Marker indicates level-one stall failure, but does not report stall failure, and control motor and continue to run under current torque, executes
The torque command of gas pedal controls the switching tube frequency upgrading of IGBT to original frequency；
On the contrary, however, it is determined that the timing duration after reclocking is during reaching the second setting duration, the output of motor
Torque is continuously target output torque, then when the timing duration after reclocking is the second setting duration, determines that motor exists
