Claim 0:
1. A method comprising:
operating, by a vehicle, a pre-boot electronic control unit (ECU) in an always on state while at least one ECU is operating in a low-power state;
detecting, by the pre-boot ECU, a triggering of a pre-booting condition based on one or more interactions with a vehicle, wherein detecting the triggering of the pre-booting condition comprises determining that at least one of a plurality of pre-booting conditions was triggered;
transmitting, by the pre-boot ECU, a power-on signal to the at least one ECU, the power-on signal causing the at least one ECU to pre-boot, wherein pre-booting a respective ECU comprises: initializing a bootloader of the respective ECU and pausing the bootloader prior to the bootloader ceding control to an operating system of the ECU;
monitoring, by the pre-boot ECU, a bus of the vehicle to determine if a start condition has been triggered within a time window;
issuing, by the pre-boot ECU, a command to fully boot the at least one ECU upon determining the start condition has been triggered, wherein fully booting the respective ECU comprises issuing a command to the bootloader to resume ceding control to the operating system; and
issuing, by the pre-boot ECU, a second command to power down the at least one ECU if the start condition has not been triggered within the time window.
