盖世汽(qi)(qi)车(che)(che)网讯(xun) 继(ji)电(dian)(dian)器(qi)是(shi)汽(qi)(qi)车(che)(che)零(ling)部件中一(yi)款重要的(de)(de)(de)电(dian)(dian)子元器(qi)件，其在汽(qi)(qi)车(che)(che)中的(de)(de)(de)应用(yong)量仅次于电(dian)(dian)子传感器(qi)。汽(qi)(qi)车(che)(che)舒(shu)适性、安全性的(de)(de)(de)不断提(ti)高，必(bi)然(ran)导致其对汽(qi)(qi)车(che)(che)继(ji)电(dian)(dian)器(qi)需求的(de)(de)(de)不断上(shang)升(sheng)。预计(ji)到2013年(nian)，平(ping)均每(mei)辆汽(qi)(qi)车(che)(che)所用(yong)的(de)(de)(de)继(ji)电(dian)(dian)器(qi)总(zong)数将(jiang)由现在的(de)(de)(de)20只(zhi)左右上(shang)升(sheng)到30～35只(zhi)。

　　随着(zhe)近(jin)年(nian)(nian)来汽(qi)(qi)车(che)电(dian)(dian)(dian)(dian)子(zi)(zi)、电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)产品的(de)(de)(de)发展，汽(qi)(qi)车(che)继电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)也得到(dao)了(le)跨越(yue)式(shi)的(de)(de)(de)发展，世(shi)界汽(qi)(qi)车(che)继电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的(de)(de)(de)生产和(he)销售正呈逐步(bu)上(shang)升趋(qu)势。预计未(wei)来几年(nian)(nian)，汽(qi)(qi)车(che)的(de)(de)(de)电(dian)(dian)(dian)(dian)子(zi)(zi)化(hua)程度将会不断提升，汽(qi)(qi)车(che)行业对汽(qi)(qi)车(che)电(dian)(dian)(dian)(dian)子(zi)(zi)电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的(de)(de)(de)需(xu)求也将日益增加。2011年(nian)(nian)世(shi)界汽(qi)(qi)车(che)保有量(liang)将达到(dao)10亿辆(liang)(liang)，年(nian)(nian)产量(liang)为(wei)7500万(wan)辆(liang)(liang)，如(ru)以(yi)每(mei)辆(liang)(liang)汽(qi)(qi)车(che)上(shang)继电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)平(ping)均用(yong)量(liang)为(wei)20只(zhi)、每(mei)辆(liang)(liang)汽(qi)(qi)车(che)每(mei)年(nian)(nian)维修用(yong)继电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)平(ping)均用(yong)量(liang)为(wei)10只(zhi)、汽(qi)(qi)车(che)修配(pei)量(liang)按保有量(liang)的(de)(de)(de)10%计算，则2012年(nian)(nian)世(shi)界汽(qi)(qi)车(che)继电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)市(shi)场需(xu)求量(liang)将突破25亿只(zhi)。由此可见，汽(qi)(qi)车(che)继电(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的(de)(de)(de)发展空间(jian)非常巨大。
