The invention provides a vehicle control system and a program writing method. The purpose of the present invention is to shorten the work time for managing a program of an ECU mounted in a vehicle and improve the manufacturing efficiency of the vehicle. The vehicle control system is provided with: a vehicle control unit which is provided with a non-volatile program storage unit and which controls a function unit mounted in a vehicle by executing a program stored in the program storage unit; and a main control unit connected to the vehicle control unit, the main control unit including a nonvolatile main storage unit, and the main control unit storing, in the main storage unit, write data for writing a program to the program storage unit. The main control unit is capable of executing a write process for writing a program to a program storage unit included in the vehicle control unit on the basis of the write data, selects a control unit to be processed, which is the target of the write process, from among the plurality of vehicle control units on the basis of a predetermined selection condition, and transmits a wake-up request to the control unit to be processed. Then, write processing is performed on the processing target control unit.

    本发明提供车辆控制系统和程序写入方法。缩短用于管理搭载于车辆的ECU的程序的作业时间,实现车辆的制造效率的提高。该车辆控制系统具备:车辆控制部,其具备非易失性的程序存储部,通过执行存储于程序存储部的程序来控制搭载于车辆的功能部;以及主控制部,其与车辆控制部连接,主控制部具备非易失性的主存储部,主控制部将用于向程序存储部写入程序的写入用数据存储在主存储部中,主控制部能够基于写入用数据执行向车辆控制部所具有的程序存储部写入程序的写入处理,主控制部基于规定的选择条件,从多个车辆控制部中选择作为写入处理的对象的处理对象控制部,主控制部向处理对象控制部发送唤醒请求,之后,针对处理对象控制部进行写入处理。
