本發明涉及(ji)燃(ran)料電(dian)池(chi)汽車(che),尤(you)其涉及(ji)一種(zhong)燃(ran)料電(dian)池(chi)汽車(che)的跛行控制(zhi)方法(fa)及(ji)燃(ran)料電(dian)池(chi)汽車(che)。
背景技術:
1、燃料電池車(che)(che)輛發生(sheng)動力電池故障時,需要協(xie)調好各個部件(jian)的功(gong)能,使整(zheng)車(che)(che)在安全的前提(ti)下進入跛行模(mo)式,防(fang)止(zhi)整(zheng)車(che)(che)拋錨及危險的發生(sheng)。
2、中國專利cn114228494b的(de)方案公開了在(zai)動力電池發生故障,且動力電池控(kong)(kong)制(zhi)器無法上高(gao)壓時(shi),可以(yi)通過整(zheng)車(che)控(kong)(kong)制(zhi)器執(zhi)行跛(bo)行控(kong)(kong)制(zhi)策(ce)略,確(que)定電機扭(niu)矩,實(shi)現(xian)跛(bo)行功能。
3、中(zhong)國專利cn116176366a的(de)方案公(gong)開了計算燃料(liao)(liao)電(dian)(dian)(dian)池(chi)發(fa)動機(ji)的(de)允許加(jia)載(zai)功(gong)率(lv)(lv),限(xian)制(zhi)驅(qu)動電(dian)(dian)(dian)機(ji)的(de)最大(da)輸出功(gong)率(lv)(lv)不大(da)于允許加(jia)載(zai)功(gong)率(lv)(lv);將驅(qu)動電(dian)(dian)(dian)機(ji)工作在跛行(xing)模式,計算驅(qu)動電(dian)(dian)(dian)機(ji)的(de)目(mu)標請求功(gong)率(lv)(lv),通(tong)過燃料(liao)(liao)電(dian)(dian)(dian)池(chi)發(fa)動機(ji)響應目(mu)標請求功(gong)率(lv)(lv)。在動力(li)電(dian)(dian)(dian)池(chi)失(shi)效后,燃料(liao)(liao)電(dian)(dian)(dian)池(chi)發(fa)動機(ji)作為獨立的(de)動力(li)源給整車提供動力(li)。
4、上述方案(an)均未(wei)斷(duan)開動力(li)電(dian)(dian)(dian)池(chi),可能導致燃(ran)料電(dian)(dian)(dian)池(chi)發動機輸(shu)出電(dian)(dian)(dian)壓(ya)也就(jiu)不(bu)能跟隨(sui)動力(li)電(dian)(dian)(dian)池(chi)的母線電(dian)(dian)(dian)壓(ya),也就(jiu)不(bu)能滿足整車(che)無(wu)法(fa)正常運行,無(wu)法(fa)到達維(wei)修地點進行故(gu)障維(wei)修。
技術實現思路
1、鑒于上(shang)述的(de)分(fen)析,本發明實施例旨(zhi)在提供(gong)一種燃(ran)料(liao)電池(chi)汽(qi)車的(de)跛行(xing)控制方法及燃(ran)料(liao)電池(chi)汽(qi)車,用以解決現有技術(shu)存在無(wu)法跛行(xing)至設定維(wei)修站風險的(de)問題。
2、一方(fang)面,本(ben)發明實施例提供了一種(zhong)燃料(liao)電池(chi)汽車的跛(bo)行(xing)控(kong)制方(fang)法,包括如(ru)下(xia)步驟:
3、s1.定(ding)時識別燃料電池汽(qi)車是(shi)否進入跛行模式(shi);若是(shi),執行下一步;否則,控制車上能量管理(li)單元進入正常工作模式(shi);
4、s2.啟動燃料電(dian)池(chi)發動機為整(zheng)車(che)電(dian)機和整(zheng)車(che)電(dian)機外其他(ta)車(che)上(shang)用電(dian)負載供電(dian),車(che)上(shang)能(neng)量管理單元不響應加(jia)速踏(ta)板的開度,車(che)上(shang)動力電(dian)池(chi)斷開;
5、s3.獲取跛行模(mo)式(shi)下的整車需求功率(lv),控制燃料(liao)電池發動機工作在恒輸出信號模(mo)式(shi)以響(xiang)應所述整車需求功率(lv);
6、s4.控(kong)制燃(ran)料電池發動機正常工作(zuo)直(zhi)到跛行至設定維修(xiu)站,控(kong)制燃(ran)料電池汽(qi)車關機。
7、上述(shu)方案的有益效果是:提(ti)供了(le)一(yi)種燃(ran)(ran)料(liao)電(dian)(dian)(dian)池(chi)汽車(che)(che)(che)的跛(bo)(bo)行控(kong)制方法(fa),在整(zheng)車(che)(che)(che)電(dian)(dian)(dian)氣架構(gou)方案中,不增加整(zheng)車(che)(che)(che)物理的電(dian)(dian)(dian)氣部(bu)件。在跛(bo)(bo)行時動(dong)(dong)(dong)(dong)(dong)力電(dian)(dian)(dian)池(chi)無法(fa)為燃(ran)(ran)料(liao)電(dian)(dian)(dian)池(chi)車(che)(che)(che)輛提(ti)供能量(liang),此時立即斷開車(che)(che)(che)上動(dong)(dong)(dong)(dong)(dong)力電(dian)(dian)(dian)池(chi),并使用(yong)燃(ran)(ran)料(liao)電(dian)(dian)(dian)池(chi)發動(dong)(dong)(dong)(dong)(dong)機為整(zheng)車(che)(che)(che)電(dian)(dian)(dian)機和整(zheng)車(che)(che)(che)電(dian)(dian)(dian)機外其他車(che)(che)(che)上用(yong)電(dian)(dian)(dian)負載供電(dian)(dian)(dian)。燃(ran)(ran)料(liao)電(dian)(dian)(dian)池(chi)發動(dong)(dong)(dong)(dong)(dong)機輸(shu)出(chu)為恒輸(shu)出(chu)信號模式(shi)(根據需(xu)要選擇恒電(dian)(dian)(dian)壓(ya)模式(shi)或恒電(dian)(dian)(dian)流模式(shi)),避免了(le)出(chu)現燃(ran)(ran)料(liao)電(dian)(dian)(dian)池(chi)發動(dong)(dong)(dong)(dong)(dong)機輸(shu)出(chu)電(dian)(dian)(dian)壓(ya)不能跟隨動(dong)(dong)(dong)(dong)(dong)力電(dian)(dian)(dian)池(chi)的母線(xian)電(dian)(dian)(dian)壓(ya)導致整(zheng)車(che)(che)(che)無法(fa)正常運行的情況(kuang)。待燃(ran)(ran)料(liao)電(dian)(dian)(dian)池(chi)汽車(che)(che)(che)跛(bo)(bo)行回設定維(wei)修(xiu)站后,車(che)(che)(che)上各(ge)個控(kong)制器進入休眠(mian)模式(shi)。用(yong)戶體驗佳,降(jiang)低了(le)售后維(wei)修(xiu)成本(ben)。
