Scalable software-defined vehicle platform management and functions

A vehicle power management system, comprising:

• a central compute node comprising a power management control subsystem and a vehicle platform power management subsystem instantiated in the central compute node;
• a memory device configured to store data;
• and
• processing circuitry associated with the central compute node, the processing circuitry configured to:
• evaluate data that enumerates characteristics of multiple electronic control units (ECUs) of a vehicle;
• determine power usage characteristics of respective ECUs of the multiple ECUs of the vehicle from the data, the power usage characteristics including power requirements and available power states;
• determine a power usage policy to apply in the vehicle based on the power usage characteristics of respective ECUs and operational conditions of the vehicle,
• wherein the power usage policy includes restrictions for the vehicle and the respective ECUs;
• and
• generate, based on the power usage policy of the vehicle, control signals to change power states used by the respective ECUs,
• wherein the vehicle platform power management subsystem receives data from the respective ECUs of the vehicle and provides, based on the received data, data structures to the power management control subsystem that enumerate power management capabilities of the respective ECUs.

A process of making a central compute node for a vehicle, comprising:

• assembling circuitry and a storage device of the central compute node, the central compute node to be installed in the vehicle;
• and
• loading instructions in the storage device, wherein the instructions, when executed by the circuitry, cause the central compute node to:
• instantiate a power management control subsystem to control power usage of multiple electronic control units (ECUs) of the vehicle,
• wherein the control of the power usage is based on:
• power usage characteristics of respective ECUs of the vehicle, the power usage characteristics including power requirements and available power states;
• and
• a power usage policy applied in the vehicle based on the power usage characteristics of the respective ECUs, power usage characteristics of the vehicle, and operating conditions of the vehicle and the respective ECUs;
• and
• providing, based on the power usage policy of the vehicle, control signals to change power states of the respective ECUs,
• wherein the control signals are generated via a central compute node of the vehicle comprising a power management control subsystem and a vehicle platform power management subsystem, and
• wherein the vehicle platform power management subsystem receives data from the respective ECUs of the vehicle and provides, based on the received data, data structures to the power management control subsystem that enumerate power management capabilities of the respective ECUs.
