Vehicle control system, non-transitory computer-readable medium, and vehicle steering system

A non-transitory computer-readable medium storing an integrated control program to be applied to a vehicle control system including an integrated control device that centrally controls a plurality of vehicle systems including a vehicle steering system for steering a vehicle, and a steering control device that controls the vehicle steering system, the integrated control device and the vehicle steering system being connected to each other via an in-vehicle network to communicate with each other,

• processes of controlling the vehicle steering system including a first control process to be executed by the integrated control device and a second control process to be executed by the steering control device,
• the integrated control program being configured to cause the integrated control device to execute the first control process, wherein:
• the first control process is a process of calculating a steering control value to be used by the steering control device including a steering control program to control the vehicle steering system in the second control process executed in accordance with the steering control program, and is a process using a control parameter set in association with a behavior of the vehicle;
• and
• in the first control process, the steering control value is calculated based on information obtained from the vehicle steering system via the in-vehicle network.
