Technical field

The present invention relates to Clutch Technology fields, more specifically, more particularly to it is a kind of for demarcating automobile clutch position The method set.

Background technique

Automobile clutch position sensor is the sensor that a kind of pair of clutch on-off situation is detected, when work, from Clutch position sensor and fixed magnet on the clutch interact, and are become by the Hall chip induced magnetic field in sensor Change, measures the change in location of permanent magnet to demarcate the change in location of clutch.The clutch position sensor of the prior art is adopted more It is designed with one chip, because being required to be limited to magnetic field strength by the size and chip of installing magnet, clutch can be tested accurately Stroke be restricted, detection accuracy is not high, can not demarcate the clutch of long stroke.

Summary of the invention

It is a kind of for demarcating automobile clutch position it is an object of the invention in view of the above shortcomings of the prior art, provide Method, detection accuracy is high, can demarcate the clutch of long stroke.

To achieve the above object, the technical solution adopted by the present invention is that: it is a kind of for demarcating the side of automobile clutch position Method is demarcated using the fixed magnet on the clutch of clutch position sensor cooperation of dual chip, scaling method The following steps are included:

Step 1: the changes of magnetic field of dual chip induced magnet, difference output signal S1 and S2；

Step 2: signal S1 and S2 input microprocessor；

Step 3: microprocessor carries out linear process to signal S1 and S2, signal is combined into one, linear signal S is obtained；

Specific embodiment

The present invention is described in further detail with reference to the accompanying drawing, but does not constitute any limitation of the invention.

Method provided by the present invention for demarcating automobile clutch position is sensed using the clutch position of dual chip The fixed magnet on the clutch of device cooperation is demarcated, clutch position sensor used in the present invention, configuration with The clutch position sensor of the prior art is roughly the same, the difference is that, traditional clutch position sensor is single Piece sensor, and the present invention uses twin-core chip technology, the dual chip (chip 1 and chip 2 2) in sensor is mounted on micro- On the pcb board 4 of processor 3, as shown in Figure 1, dual chip 1,2 and microprocessor 3 connect between the power supply line and ground wire of pcb board 4, The input terminal of the signal output end connection microprocessor 3 of dual chip 1,2, the output end of microprocessor 3 export linear signal, are used for Demarcate the position of clutch.

Fig. 2 show method of the present invention for demarcating automobile clutch position, comprising the following steps:

Step 1: the changes of magnetic field of dual chip induced magnet, difference output signal S1 and S2；

Step 2: signal S1 and S2 input microprocessor；

Step 3: microprocessor carries out linear process to signal S1 and S2, signal is combined into one, linear signal S is obtained；

Step 4: microprocessor exports linear signal S；

Step 5: demarcating the position of clutch by linear signal S.

In above-mentioned steps three, microprocessor is to signal S1 and the S2 process handled as shown in figure 3, when dual chip After signal S1 and S2 input microprocessor, signal S1 and S2 are judged by microprocessor, first judge whether signal S1 is effective Linear output, if so, the whether effectively linear output of signal S2 is judged again, it is micro- if signal S2 is not exported linearly Processor only carries out linear process to signal S1；If signal S2 is also linearly exported, microprocessor can be to signal S1 and S2 Linear process is carried out simultaneously；If signal S1 is not exported linearly, microprocessor judges whether signal S2 linearly exports again, such as Fruit signal S2 is linearly exported, then microprocessor only carries out linear process to signal S2；If signal S2 is not also exported linearly, Then microprocessor determines invalidating signal, reports an error.The knot that microprocessor will individually be handled or be handled simultaneously to signal S1 and signal S2 Fruit carries out integrated treatment again, finally obtains linear signal S, and the position of clutch is demarcated by signal S.

Fig. 4 show the output signal of dual chip before treatment after comparison diagram, in figure, signal S1 is provided by chip one, Signal S2 is provided by chip two.Figure 4, it is seen that before treatment, signal S1 is in-L/2 to the segment of+△/2 with stroke The linear output of variation, but be saturated in+△/2 to the section+L/2 segment signal；Signal S2 accompanies in-△/2 to+L/2 segment Cheng Bianhua is linearly exported, but is saturated in-L/2 to the section segment signal of-△/2.Signal S1 and S2 is handled by microprocessor 3 Afterwards, the signal S linearly exported in the entire segment of-L/2 to+L/2 is obtained, the position of clutch is demarcated by linear signal S It sets, detection accuracy is high, can demarcate the clutch of long stroke.
