The invention discloses a system-on-chip low power consumption control method and device, a system-on-chip, electronic equipment and a vehicle, and the method comprises the steps: receiving low power consumption events sent by a plurality of central processing units of the system-on-chip, the plurality of central processing units belonging to different power domains, and when all the set low-power-consumption events of the central processing unit corresponding to the power domain are received, controlling the power domain to enter a set low-power-consumption mode corresponding to the power domain. In this way, the corresponding set central processing units are configured for the multiple power supply domains of the system on chip respectively, and the corresponding set low-power-consumption modes are configured for the multiple power supply domains respectively. Further, low power consumption modes of the plurality of power domains are controlled through low power consumption events of the plurality of centra
