Iphutha lesistimu ye-PCS

Izindawo zokusebenza zezinzwa

PC - I-Pre-Crash Safety System, esetshenziswa ezimotweni zakwaToyota neLexus. Ezimotweni zezinye izinhlobo, isistimu efanayo ingase ibe negama elihlukile, kodwa imisebenzi yabo ngokuvamile ifana nomunye nomunye. Umsebenzi wohlelo ukusiza umshayeli agweme ukushayisana. Lo msebenzi wenziwa ngokukhalisa isignali ezwakalayo kanye nesignali kudeshibhodi ngesikhathi lapho isistimu yokuphepha yangaphambi kokuphahlazeka ye-PCS ithola amathuba aphezulu okushayisana kwangaphambili phakathi kwemoto nenye imoto. Ngaphezu kwalokho, uma ukushayisana kungenakugwenywa, ibopha amabhuleki ngenkani futhi iqinise amabhande ezihlalo. Ukungasebenzi kahle emsebenzini wayo kusayinwa isibani sokulawula kudeshibhodi. ukuze uqonde izimbangela ezingenzeka zephutha le-PCS, udinga ukuqonda isimiso sokusebenza kwalo lonke uhlelo.

Umgomo wokusebenza kanye nezici zohlelo lwe-PCS

Ukusebenza kohlelo lweToyota PCS kusekelwe ekusetshenzisweni kwezinzwa zesithwebuli. Esokuqala sithi inzwa ye-radaretholakala ngemuva kwe-grille yangaphambili (i-radiator). Okwesibili - ikhamera yenzwaefakwe ngemuva kwe-windshield. Akhipha futhi amukele amaza kagesi angemuva ebangeni lamamilimitha, alinganisela ukuba khona kwezithiyo phambi kwemoto nebanga lokuya kuyo. Ulwazi oluvela kubo lufakwa kukhompuyutha emaphakathi, okuyiyona elucubungulayo futhi yenze izinqumo ezifanele.

Uhlelo lokusebenza lwezinzwa zesistimu ye-PCS

Inzwa yesithathu efanayo itholakala ubhampa wangemuva wemoto (Isistimu Yokuphepha Kwangaphambi Kokuphahlazeka Kwangemuva), futhi yakhelwe ukubonisa usongo lomthelela wangemuva. Uma isistimu ibheka ukushayisana kwangemuva okuseduze, icindezela ngokuzenzakalelayo amabhande ezihlalo futhi ivule izithiyo zekhanda zangaphambi kokuphahlazeka, ezidlulela phambili ngo-60mm. futhi phezulu 25 mm.

Ukusebenza kwenzwa ye-PCS

Uma i-PCS inquma ukuthi kungenzeka ukushayisana noma isimo esiphuthumayo, sizokwenzeka inika umshayeli umsindo nokukhanya, ngemva kwalokho kufanele yehlise ijubane. Uma lokhu kungenzeki, bese anda namathuba okuthi ishayisane, isistimu iyazivulela amabhuleki bese iqinisa ibhande lomshayeli nelomgibeli wangaphambili. Ngaphezu kwalokho, kukhona ukulungiswa okuphelele kwamandla okudambisa ama-absorbers wemoto.

Sicela uqaphele ukuthi isistimu ayirekhodi ividiyo noma umsindo, ngakho ayikwazi ukusetshenziswa njenge-DVR.

Emsebenzini walo, isistimu yokuphepha yangaphambi kokuphahlazeka isebenzisa ulwazi olulandelayo olungenayo:

• amandla umshayeli acindezela ibhuleki noma i-accelerator pedal (uma bekunomshini wokucindezela);
• isivinini semoto;
• isimo sohlelo lokuphepha ngaphambi kwesikhathi esiphuthumayo;
• ibanga nolwazi lwesivinini esihlobene phakathi kwemoto yakho nezinye izimoto noma izinto.

Uhlelo lunquma ukubhuleka okuphuthumayo ngokusekelwe kwijubane nokuwa kwemoto, kanye namandla umshayeli acindezela ngawo ibhuleki. Ngokufanayo, i-PCS isebenza uma kwenzeka ukushibilika eceleni kwemoto.

I-PCS iyasebenza uma izimo ezilandelayo zifinyelelwa:

• isivinini semoto singaphezu kuka-30 km/h;
• ukubhuleka okuphuthumayo noma ukutholwa kwe-skid;
• umshayeli nomgibeli ongaphambili babophe amabhande.

Qaphela ukuthi i-PCS inganikwa amandla, ikhutshazwe, futhi isikhathi sesexwayiso sokushayisana singalungiswa. Ngaphezu kwalokho, ngokuya ngezilungiselelo nemishini yemoto, isistimu ingaba noma ingabi nawo umsebenzi wokuthola abahamba ngezinyawo, kanye nomsebenzi wokubhuleka ngempoqo phambi kwesithiyo.

Iphutha le-PCS

Mayelana nephutha ohlelweni lwe-PCS lomshayeli isibani senkomba kumasignali edeshibhodi ngegama elithi Hlola i-PCS noma i-PCS nje, enombala ophuzi noma osawolintshi (imvamisa bathi i-PCS ibambe umlilo). Kungaba nezizathu eziningi zokwehluleka. Lokhu kwenzeka ngemva kokuvulwa kwemoto, futhi i-ECU ihlola zonke izinhlelo zokusebenza kwazo.

Isibonelo senkomba yephutha ohlelweni

Ukuqhekeka okungenzeka kwesistimu ye-PCS

Ukuphazamiseka ekusebenzeni Kohlelo Lwe-Check PCS kungabangelwa izizathu ezihlukahlukene. Kulezi zimo ezilandelayo, isibani esikhanyisiwe sizocisha futhi uhlelo luzophinde lutholakale lapho izimo ezijwayelekile zenzeka:

• uma inzwa ye-radar noma inzwa yekhamera iye yashisa kakhulu, isibonelo elangeni;
• uma inzwa ye-radar noma inzwa yekhamera ibanda kakhulu;
• uma inzwa ye-radar kanye nomfanekiso wemoto zimbozwe ukungcola;
• uma indawo ese-windshield phambi kwekhamera yezinzwa ivinjwe okuthile.

Izimo ezilandelayo nazo zingadala amaphutha:

• ukwehluleka kwamafuse kumjikelezo wokuphakelwa kwamandla weyunithi yokulawula ye-PCS noma isekethe yokukhanya kwamabhuleki;
• ukukhishwa kwe-oxidation noma ukuwohloka kwekhwalithi yoxhumana nabo ku-terminal block yalabo abahlotshaniswa nokusebenza kohlelo lokuphepha ngaphambi kokuphahlazeka;
• ukuphula noma ukwephula ukufakwa kwekhebula lokulawula kusuka ku-radar sensor kuya ku-ECU yemoto;
• ukwehla okukhulu kwezinga le-brake fluid ohlelweni noma ukugqoka kwama-brake pads;
• i-voltage ephansi evela ebhethrini, ngenxa yokuthi i-ECU ibheka lokhu njengephutha le-PCS;
• Bheka futhi futhi ulinganise kabusha ama-radar.

Izindlela zesisombululo

Indlela elula engasiza esigabeni sokuqala ukusetha kabusha ulwazi lwephutha ku-ECU. Lokhu kungenziwa ngokuzimela ngokunqamula itheminali enegethivu ebhethrini imizuzu embalwa. Uma lokhu kungasizi, funa usizo kumthengisi weToyota ogunyaziwe noma izingcweti eziqeqeshiwe nezithenjwayo. Bazosetha kabusha iphutha nge-elekthronikhi. Kodwa-ke, uma ngemuva kokusetha kabusha iphutha livela kabusha, udinga ukubheka imbangela yalo. Ukuze wenze lokhu, yenza okulandelayo:

• Hlola i-fuse kusekethe yamandla ye-PCS ukuze uthole i-fuse ephephezelayo.
• KwiToyota Land Cruiser, udinga ukuhlola amandla kuphinikhodi yesi-7 yesixhumi esinamaphini angu-10 weyunithi ye-PCS.
• Hlola oxhumana nabo kuzixhumi zamabhulokhi emilenzeni yomshayeli nomgibeli ukuze uthole i-oxidation.
• Bheka isixhumi sebhande lesihlalo se-ECU ngaphansi kwesiteringi.
• Hlola ubuqotho bekhebuli exhunywe ku-radar yangaphambili (etholakala ngemva kwe-grille). Ngokuvamile le nkinga ivela ngezimoto zeToyota Prius.
• Hlola ifuzi yesekethe yesibani sokumisa.
• Hlanza i-radar yangaphambili kanye nophawu lwegrille.
• Hlola ukuthi i-radar yangaphambili ihambile yini. Uma kunesidingo, kufanele ilinganiswe kumthengisi weToyota ogunyaziwe.
• Hlola izinga le-brake fluid ohlelweni, kanye nokuguga kwama-brake pads.
• Ku-Toyota Prius, isignali yephutha ingase yenzeke ngenxa yokuthi amabhethri okuqala akhiqiza i-undervoltage. Ngenxa yalokhu, i-ECU ikhombisa ngephutha ukwenzeka kwamanye amaphutha, okuhlanganisa nokusebenza kwe-PCS.

ulwazi olwengeziwe

Ukuze uhlelo lwe-PCS lusebenze kahle, udinga ukuthatha izinyathelo zokuvimbelaukuvumela izinzwa ukuthi zisebenze ngokujwayelekile. Ngenzwa ye-radar:

Isibonelo sendawo yenzwa ye-radar

• njalo gcina inzwa kanye nomfanekiso wemoto uhlanzekile, uma kunesidingo, usule ngendwangu ethambile;
• ungafaki noma yiziphi izitikha, kuhlanganisa nezibonisa ngale, kwinzwa noma uphawu;
• ungavumeli ukushaywa okunamandla ku-sensor kanye ne-radiator grille; uma kwenzeka umonakalo, thintana ngokushesha ne-workshop ekhethekile ukuze uthole usizo;
• ungayiqondi inzwa ye-radar;
• ungashintshi isakhiwo noma isifunda senzwa, ungayimbozi ngopende;
• shintsha inzwa noma i-grille kuphela komele iToyota ogunyaziwe noma esiteshini sokuhlinzeka ngamasevisi esinamalayisensi afanele;
• ungayisusi ilebula kunzwa eshoyo ukuthi ihambisana nomthetho ophathelene namaza omsakazo ewasebenzisayo.

Ngekhamera yenzwa:

• njalo gcina iwindshield ihlanzekile;
• ungafaki i-antenna noma unamathisele izitika ezihlukahlukene ku-windshield phambi kwekhamera yezinzwa;
• lapho i-windshield ebhekene nekhamera yenzwa ihlanganiswe ne-condensate noma iqhwa, sebenzisa umsebenzi wokuqeda inkungu;
• ungambozi ingilazi ebhekene nekhamera yenzwa nganoma yini, ungafaki i-tinting;
• uma kukhona imifantu ku-windshield, yishintshe;

• ungawashintshi amalambu emoto;
• uma udinga ukulungisa umthwalo omkhulu ophahleni, qiniseka ukuthi awuphazamisi ikhamera yenzwa.

Isistimu ye-PCS ingaphoqeleka ukuthi icishe. Ukuze wenze lokhu, sebenzisa inkinobho etholakala ngaphansi kwesondo lokuqondisa. Ukuvala shaqa kufanele kwenziwe ezimweni ezilandelayo:

• lapho udonsa imoto yakho;
• lapho imoto yakho idonsa inqola noma enye imoto;
• lapho uthutha imoto kwezinye izimoto - umshini noma izinkundla zesitimela, imikhumbi, izikebhe, njalonjalo;
• ngenkathi uphakamisa imoto ku-elevator nethuba lokujikeleza kwamahhala kwamasondo;
• lapho uhlola imoto ebhentshini lokuhlola;
• lapho ulinganisa amasondo;
• uma kwenzeka i-bumper yangaphambili kanye/noma inzwa ye-radar ilimele ngenxa yomthelela (njengengozi);
• lapho ushayela imoto enephutha;
• lapho ushayela ngaphandle komgwaqo noma unamathela kusitayela sezemidlalo;
• ngomfutho wesondo ophansi noma uma amathayi egqoke kakhulu;
• uma imoto inamanye amathayi kunalawo ashiwo emibhalweni;
• ngamaketanga afakwe emasondweni;
• lapho isondo eliyisipele lifakwe emotweni;
• uma ukumiswa kwemoto kushintshiwe;
• lapho ulayisha imoto ngemithwalo esindayo.

isiphetho

I-PCS yenza imoto yakho iphephe kakhulu ekusebenzeni. Ngakho-ke, zama ukuyigcina isesimweni sokusebenza futhi uyigcine ivuliwe njalo. Nokho, uma ngesizathu esithile kwehluleka, kunjalo ayigxeka. Zihlole futhi ulungise inkinga. Esimeni lapho awukwazanga ukukwenza ngokwakho, thintana nomthengisi weToyota ogunyaziwe endaweni yangakini noma izingcweti eziqeqeshiwe.

Ngokwezibalo, abantu abasebenzisa ama-anchor plug ebhande lesihlalo kungenzeka kakhulu babe nenkinga ye-PCS. Iqiniso liwukuthi lapho uhlelo luqalwa, amabhande aqiniswa kusetshenziswa ama-motor eyakhelwe ngaphakathi kanye nokushintsha. Nokho, uma uzama ukuvula amabhande, kuvela iphutha okunzima ukulikhipha esikhathini esizayo. Yingakho ke asikweluleki ukuthi usebenzise amapulaki amabhandeuma imoto yakho ifakwe uhlelo lwangaphambi kokushayisana.
