It is limited to specific circuit details.
As shown in Figure 1, being related to three rigid line CRANK 2, ACC of ignition switch 1, ignition switch 1 in this embodiment
3 and IGN 4, engine control module ECM5, starting relay 6, starter 7 and accumulator 8.Wherein, the rigid line of ignition switch 1
CRANK 2, rigid line ACC 3 and rigid line IGN 4 are by access engine control module ECM5, and engine control module ECM5
Output pin is connected with starting relay 6, to be attracted when required by control starting relay 6, and by accumulator 8
Power is provided to drive starter 7 to work.
Specifically, engine control module ECM5 will be passed according to from both rigid line ACC and rigid line IGN of ignition switch 1
The signal brought judge vehicle launch key current working status (referring to Fig.2, include LOCK, ACC, ON, START tetra-
Kind of working condition), then according to the signal sent from the rigid line CRANK of ignition switch 1 to the vehicle launch judged
The current working status of key is verified, to judge whether ignition switch meets starting state.Work as engine control module
When ECM5 is judged as starting state, and meet vehicle operation entry condition (for example, whether system of vehicle transmission chain disengages, vehicle is anti-
Steal whether certification passes through) when, then it sends out instruction control starting relay 6 and is attracted, to drive starter 7 to start work
Make.After the start-up operation of starter 7, when engine control module ECM5 judgement engine start successes are (for example, can basis
The information such as engine speed, vehicle operating parameters are accordingly judged) after or startup time of engine be more than predetermined
When value (can be needed according to application to be set to any appropriate amount), then sends out instruction and disconnect starting relay 7, started with cutting off
The electric current of machine 7 terminates to start, i.e., no matter whether ignition switch 1 has been returned to operating status from starting state at this time, start
Machine control module ECM5 can cut off starter electric current, so as to safely and effectively protect starter, completely eliminate due to
Towing astern starter after engine start and cause starter to work long hours the risk being burned.
In traditional vehicle for directly controlling starter by ignition switch, starting relay is typically directly to be opened by igniting
The rigid line CRANK signals of pass lack effective diagnostic process to control for the working condition of ignition switch.In the present invention
In method, in the case where not increasing hardware, by the way that igniting switching signal decision logic is arranged in engine control module ECM
It is combined judgement come the signals sent out of three rigid lines CRANK, ACC and IGN to ignition switch, so that it may with safe and effective
The working condition of ignition switch is judged on ground, and deterministic process is very accurate, and in time efficiently.
As an example, it has been presented in Fig. 2 a kind of three rigid line CRANK 2,3 and of ACC about ignition switch 1
The specific meaning of the different conditions combination of IGN 4.As shown in Figure 2, the ignition switch letter being set in engine control module ECM
The signal combination transmitted according to rigid line ACC3 and IGN4 this two rigid lines is judged working as vehicle launch key by number decision logic
Preceding working condition (LOCK, ACC, ON or START), and the signal transmitted with rigid line CRANK2 is verified therewith.Can
It, can be when ACC=0＆IGN=1 and CRANK=1 meet simultaneously (that is, the signal of rigid line ACC is in low under selection shape
The signal of level and rigid line IGN are in high level and the signal of rigid line CRANK is in high level) it is opening for ignition switch
Dynamic state, that is, allow to judge the current working status of vehicle launch key for START.No matter moreover, being in before hard signal
Which kind of state, if there are ignition switch signal faults, show to meet starting state once meeting conditions above, to allow
Starter starts.
Incorporated by reference to referring to figs. 2 to Fig. 4, due in start-up course there may be ignition switch signal fault phenomenon,
It, can also be for example in engine control module ECM in the vehicle starter control method of the present invention in the case of optional
Or failure counter is set in other control units on vehicle or device, to pass through above-mentioned ignition switch signal
When diagnosis logic diagnoses both rigid line ACC and rigid line IGN signal, if signal assembled state is normal, i.e. example
When as met four kinds of state LOCK, ACC, ON or CRANK defined in Fig. 2, then normally switch key status；If signal group
Conjunction state is abnormal, that is, finds to combine the current of obtained vehicle launch key according to both rigid line ACC and rigid line IGN signal
(i.e. there is failure in detection igniting switching signal at this time, the ignition switch when working condition and the signal of rigid line CRANK do not match that
And it is unsatisfactory for starting state), then above-mentioned failure counter is increased into a digit as illustrated in Figure 4.
In alternative circumstances, can also the counting of the failure counter it is cumulative reach preset value (can be according to using needs
It is set into any appropriate amount) when, then outside output signal is (for example, wherein contain ignition switch hard signal failure
Failure code) to inform that signal fault occurs in ignition switch, carry out repair and maintenance accurately and in time to carry out related personnel
Processing, effectively eliminates security risk.In addition, when starter is driven and worked, it can be by the counting of the failure counter
It resets.Using the above mode, igniting switching signal rigid line failure can be effectively detected, and avoid the hair of wrong report situation
It is raw.
It, can be in conclusion since vehicle starter control method using the present invention is smaller to the change of whole vehicle
Additional hardware component cost need not substantially be increased, and more particularly to very accurate and timely and effectively judge
The working condition of ignition switch, and detect ignition switch rigid line failure, this is for preventing starter from being burnt by towing astern and overload
It is bad, avoid fault misdescription, avoid error starting etc. have remarkable result, therefore be very suitable for the method for the present invention being applied to existing vehicle
On, to give full play of these technical advantages of the present invention.
The vehicle starter control method and vehicle of the present invention is only elaborated by way of example above, this few example is only
