The starting is 4~15s in limited time.
When starter works, ECU obtains engine rotational speed signal in real time, after engine speed reaches cut-out rotating speed,
Cut off starter control circuit.
Coolant temperature is reduced and increased when the size of the cut-out rotating speed is started with engine.
The cut-out rotating speed is 400~800r/min.
When engine speed is more than zero, and current time key is at ON grades, if key is now screwed to by driver from ON
Start grades, do not start starter.
Method of testing based on the automobile starter guard method：
Method of testing includes analog detection, including：
Setting starts successfully rotating speed, when rotating speed is more than this value, detects whether to judge currently to start successfully；
Setting starts successfully rotating speed and starting is prescribed a time limit, and detection reaches starting engine turn in limited time when the starter working time
Speed, which is not reached, starts successfully rotating speed, if forbid starter to start；
The currently practical rotating speed of engine is set, input starts key signal, detects whether to forbid starter to start；
Judge that successfully rotating speed need to be modified according to engine water temperature；
Starting lasting maximum time need to be modified according to engine water temperature.
Method of testing also includes measuring on-board, including：
Key is got to start grades and does not unclamp lasting 10s, record data analyses whether to reach in engine speed
During 600rpm, ECU control cranking-motor relays are disengaged；
Test vehicle fuel injector plug-in unit is disconnected, key reaches that start grades are not unclamped lasting 10s, record data, and analysis is
ECU controls starter to disconnect automatically after no 5s；
It will test after vehicle launch success, key is twisted during idling to start grades, record data analyses whether that ECU is controlled
Cranking-motor relay not adhesive processed.
