Description

A kind of compensation method that automotive window anti-clipping system accidentally inverts
Technical field
The present invention relates to automotive window anti-pinch technical field, especially a kind of automotive window anti-clipping system prevents from accidentally inverting Compensation method.
Background technique
As automotive electronic technology develops, vehicle window automatic lifting anti-pinch has been popularized, since anti-pinch algorithm is not quite similar, vehicle Window anti-clipping system also increases mistake umklapp probability during normal rise while automatic re-ascending prevents from clipping to people.Example Such as: having one for vehicle window during vehicle falls and gos up again due to Uneven road when running car rises window in bumpy road Downward active force, this is easy to cause accidentally to invert so that anti-clipping system is mistakenly considered vehicle and clips to thing.For another example: vehicle load opens Dynamic moment, ignition point, starting of air conditioner moment, vehicle window stall moment, supply voltage can obviously fall, and vehicle window is caused obviously to subtract Speed, anti-clipping system are mistakenly considered vehicle and clip to thing, cause accidentally to invert.Although the performance of this two kinds of phenomenons like clipping to thing, The operation for violating operator is intended to, it should eliminate as far as possible, otherwise will affect user experience, damage bad brand image.
In order to avoid the generation of above situation, automotive window anti-clipping system has started setting up compensation function.Some passes through Identify that intrinsic external information (such as speed) increases intrinsic thresholding (anti-grip force setting value) to anti-clipping system, to compensate, from And avoid the generation accidentally inverted.For example, increasing judgement thresholding with the increase of automobile driving speed, the bigger thresholding increase of speed is more It is more, to achieve the effect that accidentally to invert when car by being not easy when bumpy road.This method its in vehicle operation, pass through Increase thresholding and reach not the accidentally demand of reversion, anti-pinch reversion is but increased while reducing the chance that accidentally reversion occurs Entry condition, when anti-pinch event really occurs, the anti-grip force for inverting demand is bigger, being pinched before starting inverts anti-pinch Evil increases, and has the possibility crushed.
Also have and detect whether vehicle is in jounce condition to be mended by increasing the external sensors such as gravity sensor The method repaid.This method does not do anti-pinch judgement when detecting that sensor has downward acceleration (i.e. vehicle rise), avoids Because accidentally being inverted caused by jolting.But, when vehicle window rise process just meets the generation of anti-pinch event, anti-clipping system will not for it Reversion, to there is the risk for crushing passenger.Especially in the section continuously jolted, pinch resistant functionality can hardly start, and lose Pinch resistant functionality.In addition, this method needs sensor to also increase system cost, and it is installed to sensor and fixed form There is strict demand, if fixed shakiness will will have a direct impact on judgement.
In addition, when ging up after Voltage Drop, in rise process, anti-clipping system is equally deposited when voltage fluctuates Thing is clipped to being mistakenly considered vehicle, leads to the possibility accidentally inverted.
Summary of the invention
The present invention is intended to provide a kind of can avoid accidentally inverting the Automobile occurred while pinch resistant functionality is effectively ensured The compensation method that window anti-clipping system accidentally inverts.
The compensation method that automotive window anti-clipping system of the present invention accidentally inverts, includes the following steps:
Electric current/rate curve during vehicle window rises window, in monitoring acquisition vehicle window operational process;
It according to electric current/rate curve of acquisition, is compared with electric current/rate curve when normal condition, identification vehicle window operation is No experience bumpy road stage or voltage fluctuation stage;
It is such as identified as, i.e., when bumpy sections or voltage fluctuation are undergone in vehicle window operation, obtains vehicle window falling in experience bumpy sections The electric current fallen in the Voltage Drop stage in section or voltage fluctuation stage/speed curve early period (i.e. waveform fall the stage), root It is compared, calculates with electric current/rate curve when normal condition (i.e. horizontal section situation or normal table situation) according to it Changing value delta relative to normal condition;
Using changing value delta, anti-pinch threshold value is compensated;
When vehicle is zeroed after falling rise or Voltage Drop gos up, then by offset.
The compensation method that automotive window anti-clipping system of the present invention accidentally inverts, by detection vehicle window operational process Parameter, determine whether vehicle window undergoes bumpy sections or voltage fluctuation stage, and bumpy sections are fallen into section or electricity early period Pressure Voltage Drop stage early period in fluctuating stage count counted changing value delta as offset to increase later period rise section or The anti-pinch thresholding of boost phase.Since usual automobile falls, Voltage Drop almost the same with the value of rise in bumpy sections automobile It is almost the same with the value of voltage recovery, therefore compensated using this data, offset can directly adapt to jolt the gradient or The needs of voltage fluctuation amplitude can be avoided and crush generation caused by mechanical increase thresholding, and anti-pinch is more reliable.And it is not required to Increase the sensing equipments such as gravity sensor, cost is relatively low.
Specific embodiment
A kind of compensation method that automotive window anti-clipping system accidentally inverts includes the following steps: during vehicle window rises window, prison Survey electric current/rate curve in acquisition vehicle window operational process;Judge whether vehicle window operation passes through according to electric current/rate curve of acquisition Go through bumpy sections or voltage fluctuation stage;Such as judge vehicle window operation experience bumpy sections or voltage fluctuation stage, then according to record Electric current/rate curve, calculate vehicle when bumpy road falls the Voltage Drop stage in section or voltage fluctuation stage its Electric current/speed is with respect to the changing value delta in normal condition (horizontal section situation or voltage stabilization situation);Utilize changing value Electric current/rate curve anti-pinch thresholding of the delta to vehicle window in rise section compensates;Its method compensated is by anti-pinch Thresholding subtracts changing value delta;After vehicle leaves rise section (after i.e. vehicle gos up), then offset is zeroed.
When automobile bumpiness when driving, falling section, when the more normal section of electric current/rate curve value (level road) Electric current/rate curve value wants low, calculates its low numerical value, i.e. changing value delta.And in rise section, accelerated downwards The influence of degree, electric current/rate curve value can be higher than the value of level road.It falls the low numerical value in section and rise section is high Numerical value is almost the same, therefore, changing value delta is used to compensate electric current/rate curve value of uphill way, can be eliminated The influence of upward acceleration, so that it is guaranteed that the normal starting of the pinch resistant functionality in bumpy sections.
The compensation method may determine that when vehicle enters bumpy sections using to electric current/speed acquisition monitoring Whether vehicle enters bumpy road, and when judgement enters bumpy road, it is corresponding to normal road surface to calculate descending road surface simultaneously The delta value of variation, it is using the almost the same rule of the changing value of rise process and falling process, falling process is counted Anti-pinch threshold value of the delta value to compensate rise process, i.e., subtract changing value delta for anti-pinch thresholding, generate new anti-pinch Thresholding avoids the problem that mistake inverts and anti-grip force is excessive and brings, reliable so that anti-pinch thresholding be made to adapt to the needs of upward slope process It ensure that the reasonable of anti-grip force while realizing pinch resistant functionality, avoid the generation crushed.Keep anti-clipping system more safe and reliable, Improve user experience.
The process fallen is a period of time, and changing value delta can be also to continue variation in this period, takes drop-out time In maximum changing value delta as offset, i.e. difference of the minimum point of curve early period relative to normal condition curve.Its energy Reliably prevent rise process because accidentally inverting caused by upward acceleration.
However, the selection mode of above-mentioned changing value delta, when making really to encounter pinch resistant operation during rise, anti-pinch is anti- The anti-grip force turned might have bigger than normal, and certain influence can be still generated on user experience.It is further to optimize for this situation, it can Drop-out time is averagely divided into several segments, the maximum value of each section of changing value delta is calculated separately;It will go up the time simultaneously Also correspondence is divided into corresponding several segments, each section during being gone up respectively with each section of maximum value delta symmetrical compensation.Assuming that Fall and the time of ging up is divided into three sections, then the maximum value delta1 for the changing value delta that first segment drop-out time calculates, the The maximum value delta2 for the changing value delta that two sections of drop-out times calculate, the changing value delta's that third section drop-out time calculates Maximum value delta3;Its symmetrical compensation mode be first segment go up the time compensated with delta3, second segment go up the time with Delta2 is compensated, and the third section rise time is compensated with delta1.By above-mentioned symmetrical compensation, can reliably keep away Caused by exempting from because of rise acceleration accidentally reversion simultaneously, avoid in when anti-pinch event occurs, anti-grip force it is excessive, thus into one Step improves user experience.
