一种低冰点尿素报警方法、装置、介质及车辆
By determining the type of urea used in the vehicle and the regional temperature information, a prompt message is generated to remind the user to replace the urea, which solves the problem of low-freezing-point urea crystallizing in northern regions and ensures the normal use of the vehicle.

AI Technical Summary
Existing urea alarm methods are not effective for use in northern regions where low-freezing-point urea is used, leading to crystal buildup that affects ultrasonic detection and causes vehicle malfunctions.
By determining whether the urea used in the vehicle is low-freezing-point urea, and combining the vehicle's current location and historical temperature information, a prompt message is generated to remind the user to replace the urea, and the urea concentration is continuously monitored to avoid crystallization problems.
During non-cold periods or in non-cold regions, promptly remind users to replace urea to prevent low-freezing-point urea crystallization from affecting vehicle use, ensure the accuracy of urea concentration monitoring, and improve the reliability of normal vehicle use.
