After vehicle meets idle stop state, ECU can totally judge and send idle stop request signal to TCU；TCU
After receiving this idle stop request signal, carry out idle stop conditional judgment, when meeting described idle stop condition, then open
Begin to perform the preparation of idle stop, i.e. control dual-clutch transmission and disengage driving-chain；Prepare when TCU completes to shut down
(that is, detecting after successfully disengaging), sends permission idle stop signal to ECU；Then ECU control electromotor is shut down, and to
TCU sends idle stop status signal (being 1), engine status signal is switched to stopped status simultaneously.
After engine speed comes to a complete stop (being 0), idle stop status signal can be maintained at puts 1 state, and TCU is carried out certainly
Dynamic entry condition judges, when meeting described automatic entry condition, TCU need to be maintained at the state preparing to start during this period, i.e.
When forbidding TCU control driving-chain relay status for being not prohibited by (being 0), TCU needs to keep driving-chain relay adhesive, i.e. controls
Making driving-chain described in described dual-clutch transmission adhesive, TCU needs to forbid that automatically activated signal sets to 0 (the most simultaneously
Forbid automatically starting)；If TCU detects internal fault during this period, or other reasons causes it that shutdown can not be maintained again to prepare
State, then TCU needs to send to forbid to ECU, ECU, automatically activated signal can forbid that electromotor starts automatically.When ECU judges have
After starting request, and entry condition meets automatically, then trigger and automatically start；Starter motor can again drag electromotor and complete to open
Dynamic, in automatic start-up course, engine status signal can first switch to start and switch to run again；Idle stop status signal can be

After TCU receives this request signal, idle stop conditional judgment to be carried out, idling can be carried out in the following order and stop
Machine conditional judgment:
1) whether the current shift of dual-clutch transmission is in forward gear, if meeting, continues following 2) judge,
Otherwise send and forbid that stopping signal is to ECU；
2) TCU controls two clutch separation respectively, by reading the clutch pressure sensor signal that change speed gear box gathers,
Judge that whether clutch pressure is less than predetermined threshold value (e.g., being set to 150kpa).If meeting, continue following 3) judge, otherwise
Transmission forbids that stopping signal is to ECU；
3) check dual-clutch transmission oil temperature state whether in prescribed limit, speed, gas pedal, brake step on
Whether board status meets requirement, if meeting, continues following 4) judge, otherwise send and forbid that stopping signal is to ECU；
4) TCU judges whether dual-clutch transmission exists fault, if fault-free, sends shutdown and allows idling to stop
Machine signal, to ECU, otherwise sends and forbids that stopping signal is to ECU.
Described ECU, after receiving described permission idle stop signal, controls electromotor and shuts down.
Fig. 4 is that D shelves start control flow automatically, and TCU is receiving engine idle stopped status and electromotor shutdown shape
After state, then TCU needs carry out automatic entry condition judgement in the following order and start preparation:
1) check whether speed change box clutch state is in released state, the most then enter 2) Rule of judgment, otherwise TCU
Transmission forbids that automatically activated signal is to ECU；
2) whether detection gearbox-gear is in D gear, the most then enter 3) Rule of judgment, otherwise TCU sends and forbids automatically
Enabling signal is to ECU；
3) whether detection change speed gear box exists fault, if there is not fault, then carries out startup and prepares (i.e. to control described pair of clutch
Driving-chain described in device automatic gear-box adhesive)；If there is fault, but when fault severity level is not enough to enter limping pattern, then
Continuing to carry out startup to prepare, otherwise TCU sends and forbids that automatically activated signal is to ECU；
