Adaptive dual-buffer advanced driver assistance system

By adopting an adaptive dual-buffer configuration in the ADAS system, and using the secondary buffer data to generate an electronic horizon when the primary buffer is lost, the system interruption problem caused by the loss of the electronic horizon is solved, thus realizing the continuous operation of the ADAS system and the stability of autonomous vehicles.

AI Technical Summary

Technical Problem

Existing advanced driver assistance systems (ADAS) cannot promptly recover navigation information when the electronic horizon is lost, especially in autonomous vehicles, leading to system malfunctions or operational interruptions.

Method used

An adaptive dual-buffer configuration is adopted, including a primary map data buffer and a secondary map data buffer. When the primary buffer loses data, the system switches to the secondary buffer and uses the map data in the secondary buffer to generate an electronic horizon, ensuring the continuity and stability of the system.

Benefits of technology

It enables seamless switching when the electronic horizon is lost, ensuring the continuous operation of the ADAS system, avoiding operational interruptions of autonomous vehicles, and improving the system's reliability and stability.

Abstract

A method of operating an advanced driver assistance system (ADAS) can include performing a map data reload operation on a first map data buffer containing map data obtained from a first source. A switching operation can be performed to switch from the first map data buffer to a second map data buffer containing map data obtained from a second source. An electronic horizon can be generated based on the map data contained in the second map data buffer and used to perform a first ADAS operation. Another switching operation involves switching back from the second map data buffer to the first map data buffer, which now contains map data obtained from the first source during the map data reload operation. Then, another electronic horizon can be generated based on the map data contained in the first map data buffer and used to perform one or more ADAS operations.
