I suggest you apply for the direction of automotive electronics in Tongji vehicle engineering, which can be cross-professional. As for the teaching materials, I recommend several books: Automobile Structure by Chen Jiarui, Automobile Theory by Yu Zhisheng, Automobile Design by Wang, Engine Principle by Wu Jianhua, and General Mechanical Design, all of which are the main courses of vehicles. Life is short, maybe we will die tomorrow, so do what you like bravely! Good luck!
