6) wheel rotation speed signals 168 represents that the speed of manual-gear vehicle is gradually kept to 0；And
7) battery tension signal 166 represents that the accumulator electric-quantity of described manual-gear vehicle starts the most next time.
For burn-out condition 6), when the vehicle speed value that wheel rotation speed signals 168 represents the manual-gear vehicle vehicle speed value in the first moment the second moment more than 0 and after the first moment is 0, main control module 102 judges that the speed of manual-gear vehicle is gradually kept to 0, i.e. meets burn-out condition 6).What deserves to be explained is, if it is 0 that wheel rotation speed signals 168 represents that the manual-gear vehicle vehicle speed value in the first moment situation equal to 0 potentially includes speed be natively 0 (such as stop or just started) or speed and is gradually reduced.Now, due to cannot determine whether be speed be gradually 0, therefore, and be unsatisfactory for burn-out condition 6).
During additionally, and be satisfied by when multiple entry conditions after manual-gear vehicle temporary parking is flame-out, main control module 102 judges that manual-gear vehicle needs to be again started up, and controls to make ignition coil 120 and starter relay 122 be energized, this manual-gear vehicle of lighting a fire.In one embodiment, entry condition includes:
1) master switch signal represents the master switch of manual-gear vehicle in an ON state；
2) engine rotational speed signal 162 represents that the electromotor of manual-gear vehicle is in flameout state；And
