汽车电路的画法目前有以线为主的画法和以表达原理为主的画法。前者注重汽车电器的实际安装位置,连接导线的始末端、编号、颜色、线径;后者以表达整车电路工作原理为主。本文对这两种画法进行了比较,吸取两者的优点,提出了另一种画法。该画法在整车电路布局上,采取表达原理为主的画法,即一般电子电路所采用的上正下负的方法,但从电源正极引出的导线仍按原始接法,不合并为一根,同样,因各电路搭铁方式不同,不强求用统一的一根搭铁线;在线路连接上全车都采用插接件,注重连接导线的始末端位置,不随意中途连接。并以改画的拉巴(RA'BA)L26重型载贷汽车电路图为例进行探讨。At present, there are two ways of drawing the automobile circuit diagrem, that is, the method of drawing mainly by lines, and by expressing principle. The former emphasizes actual installment position of autoeleetric equipments,the start and end of the connection wires, editoral number, colour and diameter of wire; the latter places emphasis on expressing operating principle of the whole automobile circuit. The article compares these two methods, adopts their merits and puts forward another
