Device, clutch sensor, gear position sensor, charge and discharge control module, the clutch to current vehicle, gear working status, vapour
Car generator, automobile storage battery working status, accessory power supply working status, vehicle wheel rotation rotating speed and throttle working status are examined
Survey, current vehicle engine behavior, vehicle form are then directly acquired from vehicle driving computer by data processing module
Speed is detected, and the data of detection are saved in it is spare in data processing module, while by vehicle driving computer to each
Data are shown;
3rd step, engine restarting, after completing the 3rd step, when clutch sensor, gear position sensor are in working status, car
Speed be more than 5 kilometers/hour, throttle it is in running order, after engine is in shutdown status, vapour is driven by data processing module
Car engine is again started up;When clutch sensor is discrete state, throttle is in halted state, gear position sensor is work shape
State, vehicle speed are 0 and when being kept for more than 30 seconds, then stop engine operation by data processing module, and be in work in throttle
Driven again by data processing module after state and start engine operation;When clutch sensor, gear position sensor are in work
Make state, vehicle speed is more than 5 kilometers/hour, throttle is in running order, engine is in running order, engine temperature mistake
Gao Shi, then by data processing module driving engine stop operation, and be again started up starting after engine temperature recovers normal
Machine is run, and engine operating state is shown by vehicle driving computer and again returns to second step and carries out data inspection
Survey operation.
Further, the remote supervisory and control(ling) equipment in the first step for the data server based on data communication network,
Any one in mobile intelligent terminal equipment.
Further, in the second step, the Data Detection operation assay intervals of progress are 10-120 seconds.
Further, in the 3rd step, in data processing module driving engine start operation operation, automobile is worked as
When storage battery and generator are not normally functioning, then by accessory power supply driving engine operation.
Present system forms simple, runs and manipulate of low cost, detection operation and control accuracy are high, operation automation
Degree is high, on the one hand can effectively meet the needs of the autonomous start-stop operation of vehicle engine under temporary parking idling mode, separately
On the one hand it can effectively realize vehicle under operation, promptly restart under engine abnormity shutdown status and engine failure state
Lower emergency alarm and the needs of protection operation, so as to greatly improve vehicle motor reliability of operation and security.
