Information processing apparatus i.e. personal computer, for electrical power steering system to support steering operation of steering wheel in vehicle, has CPU comprising writing unit for writing new data into ROM by carrying out program

摘要

The apparatus has a CPU (41) receiving a new data write command from an external device (15) and controlling a new letter of data stored in a ROM (42). The CPU comprises a program transmission unit for transferring a reprogramming program, which is required for a data new recording mode determined by a reprogramming mode determining unit, from the ROM to a RAM. The CPU comprises a new data writing unit for writing new data into the ROM by carrying out the reprogramming program transferred to the RAM. The ROM includes a program area for storing the reprogramming program.
