6. the start-stop electrical machinery life test method according to claim 5 for hybrid vehicle, which is characterized in that institute
Stating test pattern is the cold start and hot exposure operating condition for having simulated power failure machine according to the preset time interval: when cold start, start-stop
Motor drag engine controls the ignition system fires of engine after running to setting speed, and is reaching scheduled steady operation
Time or steady operation revolving speed close engine after requiring；When hot exposure, start-stop motor drag engine runs to setting and turns
Ignition system fires after speed, reach predetermined stable work time or engine is closed in the requirement of steady operation revolving speed later.
7. the start-stop electrical machinery life test method according to claim 6 for hybrid vehicle, which is characterized in that institute
State user input data include: cycle-index, the cold start number of single cycle and hot exposure number, global cycle periodicity,
Time threshold, the cold start interval of cold start time and rotating speed of target, hot exposure time and rotating speed of target, cold start and hot exposure
Time, hot exposure interval time, engine stabilizer working time, engine stabilizer working speed.
8. the start-stop electrical machinery life test method according to claim 6 for hybrid vehicle, which is characterized in that institute
It states and judges whether to start successfully according to the tach signal of acquisition, and the step of carrying out recording and displaying, specifically include:
Judge whether to start successfully according to the tach signal of acquisition, if engine speed reaches rotating speed of target simultaneously when cold start is tested
Igniting represents and is shown as that function cold start is primary, and engine is not lighted a fire, indicates that cold start fails, though engine is lighted a fire, is setting
Revolving speed miss the mark revolving speed within the scope of time threshold also illustrates that cold start fails, and when hot exposure is tested, plays power failure machine and is providing
Time threshold in engine is dragged into rotating speed of target and is lighted a fire, that is, indicate that successfully hot exposure is primary, otherwise indicates hot exposure
Failure；
At least one following parameter of recording and displaying: cold start number, success cold start number, hot exposure number and success heat rise
Dynamic number, success hot exposure number, current cycle time, setting global cycle periodicity, every circulation cold start number and hot exposure
When number, cold start rotating speed of target setting value, cold start time threshold setting value, hot exposure rotating speed of target setting value, hot exposure
Between set threshold value, cold start interval time setting value, hot exposure interval time setting value, the engine stabilizer working time, hair
Motivation steady operation revolving speed, engine speed, start-stop motor speed, engine operating temperature, operating ambient temperature.
