The invention discloses a peripheral starting method and device of a vehicle-mounted controller, equipment and a storage medium. The method is applied to a control chip in a vehicle-mounted controller. The control chip at least comprises a high-performance core and a real-time core; the method comprises the following steps: responding to a power-on signal of a control chip, loading a real-time operating system on a real-time core, and loading a time-sharing operating system on a high-performance core; initializing the non-critical peripheral according to the first configuration task through a time-sharing operation system of the high-performance core so as to start the non-critical peripheral; the first configuration task is allocated to the time-sharing operation system by the control chip; initializing the key peripheral according to the second configuration task through a real-time operating system of the real-time core so as to start the key peripheral; the second configuration task is allocated to the real-time operating system by the control chip. According to the technical scheme, the starting of the key peripheral is executed by the real-time operating system, so that the starting efficiency of the peripheral is improved.
