1. A system comprising:
a processor; and
a memory storing machine-readable instructions that, when executed by the processor, cause the processor to:
determine whether a disengagement ratio of a host vehicle is below a predetermined threshold value, the disengagement ratio of the host vehicle being at least one of a ratio between a number of system-initiated disengagements to a predetermined time period and a ratio between an amount of time that the host vehicle is in a manual mode and an amount of time that the host vehicle is in an autonomous mode;
determine whether driving conditions at an upcoming road segment are conducive for disengagement of autonomous vehicle control in the host vehicle, the driving conditions belonging to a domain in which the autonomous vehicle control is designed to operate; and
disengage the autonomous vehicle control in the host vehicle in response to at least the disengagement ratio being below the predetermined threshold value and the driving conditions being conducive for the disengagement of the autonomous vehicle control.
