Abstract: Abstract: The more common remote control technology on the market is limited to the realization of auxiliary system control such as door locks, doors and windows, and air conditioners, and has not yet achieved safe and reliable remote speed limit control for the entire vehicle. This paper designs a set of intelligent remote speed limit system for new energy vehicles. According to user needs, the vehicle can be remotely controlled on the App or monitoring platform. The vehicle's on-board terminal receives the remote control command. After that, it is stored in the memory, and the speed limit command is sent to the CAN bus. The vehicle-mounted terminal then feeds back the final execution result to the monitoring platform and App after algorithm integration based on the vehicle status and the execution result fed back by the vehicle controller. In this paper, an intelligent remote speed limit method for new energy vehicles is designed and developed, which realizes the remote setting of multiple gears of the maximum speed for different user vehicle scenarios, so as to ensure the safety of users such as the elderly and children.

摘要： 市场上较常见的远程控制技术仅限于实现门锁、门窗、空调等辅助系统控制，尚未对 整车实现安全、可靠的远程限速控制。文章设计了一套新能源汽车车辆智能远程限速系统， 根据用户需求，可在 App 端或监控平台端对车辆进行远程限速控制。该车辆的车载终端接收 到远程控制指令后存储至内存，并向 CAN 总线发送限速指令。车载终端再根据整车状态及整 车控制器反馈的执行结果，经算法整合后，将最终执行结果反馈至监控平台和 App。文章设 计开发了一种新能源汽车车辆智能远程限速方法，实现了针对不同用户用车场景，远程设置 最高车速多个挡位，确保老人和小孩等用户用车安全。
