- 应用说明英语AI 生成的摘要: Power management functions in R-Car Series 3rd Generation address two key automotive requirements: rapid system boot upon engine start and effective heat generation control. Key software features include CPU hotplug, CPU idle, CPU frequency scaling, runtime power management, system suspend to RAM, intelligent power allocation, emergency shutdown, and capacity aware migration. These functions optimize power consumption, manage thermal conditions, and maintain system responsiveness. High-speed booting enables immediate resumption of multimedia and navigation functions, enhancing user comfort. Thermal management prevents overheating by dynamically adjusting CPU performance and power supply. The document details software specifications, relationships between requirements and functions, and practical control examples.
