In being directed to prior art, automatic gear-box is difficult to distinguish the pulse obtained by position sensor in shift process
The problem of the verity of signal, this application discloses a kind of automatic gear box control method and device.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Flow charts of the Fig. 1 for automatic gear box control method disclosed in the present embodiment.
Present embodiment discloses a kind of automatic gear box control method, referring to Fig. 1, methods described includes：
Step S101：Obtain the first signal value of the pulse signal that position sensor sends；
Step S102：Obtain the secondary signal value of the complementary signal of the pulse signal；
Step S103：Judge the absolute value of first signal value and secondary signal value and with baseline signal value difference
Whether it is more than preset value, if execution step S1041, otherwise execution step S1042；
Step S1041：The first comparison signal is exported, automatic gear-box switches to limp-home mode；
Step S1042：The second comparison signal is exported, automatic gear-box performs gear shift operation according to first signal value.
In automatic gear-box control process, when the position sensor normal work, according to the position sensor
First signal value of the pulse signal of acquisition and the secondary signal value sum being complementary to are usually a fixed value, and here is designated as base
Calibration signal value.
May there is certain error in view of the position signalling of position sensor output, cause first signal
Value and the secondary signal value sum being complementary to change, and the application causes first signal value and is complementary to described
The range of error of secondary signal value sum made and further having limited, as long as i.e. the first signal value and secondary signal value and with

In adjustable value, such as the above embodiments of the present application, it is preferred that the size of the preset value can be 10, i.e., described first signal
When the difference of value and the secondary signal value sum and the reference signal is more than 10, you can think to be obtained by the position sensor
The signal for taking is untrue, breaks down during the position sensor output pulse signal.
It is understood that when the pulse signal got by the position sensor is untrue, in order to more preferable
Prompting user position sensor break down in output pulse signal, in the application such scheme, when judging described first
When the absolute value of signal value and secondary signal value and with baseline signal value difference is more than preset value, alarm signal can also be exported
Number.The type of wherein described alarm signal is varied, makes prompting to user as long as ensure that, such as described warning
Signal can be audio alert signal or word alarm signal, the prompting user position sensor output in the way of voice or word
Pulse signal it is untrue.
