[0026] It should be noted that SOA (Service Orient Architecture) here refers to service-oriented architecture. The cruise control and state management unit can implement adaptive cruise logic control and state machine jump. The unit can handle speed planning services, vehicle status services, and HMI notification services. Based on the service interface, the unit can obtain the current controlled vehicle speed and vehicle status information, and calculate the longitudinal control force that the current vehicle should output, and perform braking and torque control.

The unit can call the sound alarm unit and the visual alarm unit for combined control. Preferably, the unit can provide an external service interface, and other units can communicate by calling, that is, the service of the unit can be called by functional units other than the adaptive cruise system.
