Abstract

The invention provides a motor anti-pinch parameter regulating method. An operator inputs the parameters of a motor into a function computation module of a regulator through a data input module of the regulator, wherein the parameters of the motor include the maximum value (n0max) and the minimum value (n0min) of no-load speed, the maximum value (n1max) and the minimum value (n1min) of rated speed and rated point torque T1; the regulator automatically outputs a regulating success result or regulating failure prompt and stores and outputs the crucial parameters of motor anti-pinch design when regulating is successful. According to the motor anti-pinch parameter regulating method provided by the invention, the parameters of any motor are input to the regulator manually, and then the situation whether the motor has an anti-pinch function can be judged and crucial parameters which need to be written in a motor anti-pinch module can be obtained. Compared with the prior art, the method provided by the invention has the advantages that the parameters of the motor do not need to be tested by a small batch of motors, therefore, time of relevant personnel can be saved; in addition, the anti-pinch capability of the motor does not need to be tested in a way of manual drafting, therefore, design flow is simplified.

Description

A kind of motor anti-pinch parameters setting method

Technical field

The present invention relates to a kind of motor anti-pinch parameters setting method.

Background technology

For the consideration of secure context and the requirement of relevant laws and regulations, there is the many places shutter member need possess pinch resistant functionality on the automobile, such as power windows, power sunroof, electronic lifting door etc.; The current motor that is used for these systems is permanent magnet direct current motor entirely.Because permanent magnet direct current motor is the parts that manufacturing is had relatively high expectations, its performance of motor that any motor manufacturer works it out all can't with Design Theory in full accord, therefore the actual parameter of motor all has certain tolerance, also promptly in actual use the parameter of motor be a scope.

In the anti-pinch of shutter member, because controller can't be known current motor properties curve, and the tolerance of motor performance plays a key effect to the size of anti-pinch power, if the motor performance tolerance is very big, will directly make anti-clipping system that mistake anti-pinch or non-anti-pinch take place, simultaneity factor also can't satisfy laws and regulations requirement, and this problem that causes because of the motor performance deviation will directly cause the exploitation of system to be failed.

For judging whether a kind of motor can be used for the anti-pinch module, and traditional way is:

1) gets a small quantities of motor and experimentize (for example 20), detect each motor properties data, according to each motor properties curve of experimental data match;

2) all motor properties curves are gathered and contrast, get average and do the typical curve that preparation prestores in the program;

3) typical curve is drawn, compare,, whether can be used for anti-pinch to judge motor by doing the error amount size of figure method estimation anti-pinch power with the curve of this batch (for example 20) motor.

The shortcoming of this way is the length that expends time in, and is inconvenient to operate, and human cost is very high simultaneously.
