”運筆" means brush strokes or strokes of a writing (painting). I have never seen the word "将車" in any Japanese writings. If it is "将軍", it means a shogun or a general.

As Kazuko-san also mentioned, I don't recognize 将車 neither. It can be an old Japanese word. But I am wondering if you meant 書写（しょしゃ）. If so, 書写　means copying a sample writing of Japanese characters to practice how correctly and beautifully to write the Japanese character(s). When we practice 書写, 運筆 is one of the important keys to write a word correctly and beautifully.
