AI Technical Summary

Technical Problem

In the existing unmanned vehicle technology, the broadcast signal propagation of the CAN bus causes all ECUs to be awakened, increasing the power consumption of the vehicle resource and reducing the battery life.

Method used

A domain controller for an unmanned vehicle is designed, which communicates with the physical key control component through the first control module and the second control module communicates with the digital key device, and switches to the working mode only when a corresponding wake-up signal is received, reducing unnecessary wake-up.

Benefits of technology

Reduces the number of wake-up controllers, increases the power-on startup speed, saves the power consumption of the domain controller, reduces the power consumption of the entire vehicle, and extends the battery life.

Abstract

The invention discloses a domain controller for an unmanned vehicle, the unmanned vehicle comprises at least one entity key control assembly, the unmanned vehicle can communicate with digital key equipment, the domain controller comprises a first control module, and the first control module can communicate with the entity key control assembly; the second control module can communicate with digital key equipment, and the second control module is connected with the first control module; when the first control module receives a wake-up signal of the entity key control assembly, the first control module is switched from the sleep mode to the working mode, and when the second control module receives a wake-up signal of the digital key device, the second control module is switched from the sleep mode to the working mode. Vehicle power consumption can be reduced, and the service life of the battery is prolonged.
