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.
