AI summary

A vehicle control system is communicably connected with an electronic controller and a control circuit. The control circuit is controlled by the electronic controller as a control target. The vehicle control system communicates with the electronic controller using a control communication frame and communicates with the control circuit using a circuit communication frame. The control communication frame and the circuit communication frame have different formats from one another. The vehicle control system includes at least one of a first sequence circuit converting the control communication frame into the circuit communication frame or a second sequence circuit converting the circuit communication frame into the control communication frame.
