The Reliability Test Methods for Powertrain Unit of
Light-Duty Hybrid Electric Vehicle (ISG Type)
1 Scope
This Standard specifies the reliability test methods for powertrain unit of light-duty
hybrid electric vehicle (ISG type).
This Standard is applicable to the powertrain unit for Type-M1, Type-N1 and Type-M2
hybrid electric vehicle (ISG type) with maximum design total mass no greater than 3.5t.
This Standard is not applicable to the idle start-stop function.
2 Normative References

dated documents, only the versions with the dates indicated are applicable to this
document; for the undated documents, only the latest version (including all the
amendments) are applicable to this document.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 19596 and
the following apply.
3.1 Hybrid control unit (HCU)
5.3.3 Initial test data for performance of engine and motor shall adopt the performance
test data provided by the manufacturer.
5.4 Reliability test
The reliability test shall be performed as per the Appendix B.
5.5 Inspection and maintenance
5.5.1 General
Inspection and maintenance shall be carried out according to the following
requirements; but the contents and cycle may be appropriately increased and
decreased. The inspection results and maintenance situations shall be recorded in
detail.
5.5.2 Inspection at any time
Use the fault diagnosis device, instrument and computer to check the operation data
at any time. If the limit range is exceeded, according to the severity of the fault, issue
an alarm or emergency stop for processing and maintenance. If it is the failure of the
powertrain unit, it shall be counted as a failure stop. Then record the running time for
shutdown, causes and treatment situations.
5.5.3 Inspection records per 1h
5.5.3.1 Record per hour the reliability accumulative running time, powertrain unit output
torque, engine speed, engine coolant outlet temperature, engine oil temperature, input
DC bus voltage and current of the motor controller, voltage and current of each output
phase of the motor controller, motor coolant outlet temperature (if the system contains
the cooling device of the motor coolant); if the motor winding is equipped with a
thermistor temperature sensor, then the operating temperature of the motor winding
shall checked together.
5.5.3.2 After the cold start, the pre-heating time of the powertrain unit shall not be
included int the reliability accumulative time.
5.5.4 Inspection and maintenance every 24h
5.5.4.1 The engine part shall be performed as per the 10.3 in GB/T 19055-2003.
5.5.4.2 Check the oil, water and gas leakage of the powertrain unit. Keep the
powertrain unit and its surrounding area clean; so that detect the leaks in a timely
manner.
5.5.4.3 Check whether the motor bearing and the motor body rotate smoothly, and
have abnormal noise.

(Normative)
Reliability Test Program of Powertrain Unit
B.1 The engine throttle is fully open; speed is uniformly raised from nM to nP for 90s;
during this period, the motor runs for 30s at the peak electric power; then runs for 60s
at the rated electric power.
B.2 The engine runs stably at the speed nP for 210s; during this period, the motor runs
at the rated power generation for 10s, runs for 10s at the rated electric power, then
runs for 10s at the rated power generation; cycles repeatedly.
B.3 The engine speed is uniformly reduced to the speed nM for 90s; during this period,
the motor runs at the rated power generation.
B.4 The engine runs stably at the speed nM for 210s; during this period, the motor runs
for 10s at the rated power generation, runs for 10s at the rated electric power, then
runs for 10s at the rated power generation; cycles repeatedly.
B.5 Repeat the Procedures B.1 ~ B.4 once; then perform Procedures B.1 and B.2 once.
Engine throttle is closed; engine speed drops to idle speed (ni), runs to 1770s; engine
throttle is set to 40%, the engine speed is uniformly raised to 105% rated speed (nt) or
raised to the maximum speed specified by the engine manufacturer for 15s±6s; then
close the throttle evenly, the speed is reduced to nM for 15s±6s; during this period, the
motor has no power output.
B.6 At this time, a working condition cycle for the reliability test is finished for 1800s,
see Figure B.1. The operating schedule of the working conditions is shown in Table
B.1. The reliability test of the entire powertrain unit is continuously operated for 800
cycles, and accumulative running time of 400h.
B.7 The transition time for the change of motor working conditions is less than or equal
to 1s. In the test, if the motor system has insufficient output power due to the protection,
then it shall be operated at the maximum output capacity of the motor at this time.
