US 2023/0264641 A1 · Vehicle Power Architecture, Trigger, and Method of Initiating the Wake-Up of Functional Blocks

Abstract

A vehicle power architecture is disclosed that includes a plurality of functional blocks for implementing functions and a power supply input for receiving a power supply. The vehicle power architecture also includes an electronic control unit (ECU) comprising a plurality of power control switches, each being switchable between an open state where at least one of the functional blocks is disconnected from the power supply input and a closed state where the at least one functional block is connected to the power supply input. The vehicle power architecture further includes a trigger having a wake-up input for configuring the plurality of power control switches between the open state and the closed state.
