AI Technical Summary

⚠Technical Problem

Existing screen heating control methods suffer from coarse control, slow response, temperature overshoot, and high energy consumption in extreme low-temperature environments, and may also affect the stability of the power supply system, making them unsuitable for the complex dynamic low-temperature operating conditions of industrial vehicles.

⚗Method used

An adaptive predictive heating method based on a dynamic thermal inertia model is adopted. By acquiring the screen and ambient temperatures in real time, the dynamic thermal inertia model is used to predict the temperature change trend, dynamically adjust the heating power, and combine it with adaptive PID control to achieve precise temperature control and energy consumption optimization.

🎯Benefits of technology

Achieving stable screen temperature control under extreme low temperatures reduces energy consumption, extends vehicle battery life, avoids battery undervoltage protection, ensures screen display stability and clear information reading, and adapts to complex operating conditions.

Abstract

The application discloses a screen self-adaptive predictive heating method based on a dynamic thermal inertia model, and belongs to the technical field of electronic device display. The method comprises the following steps: acquiring a screen temperature and an ambient temperature in real time; when the screen temperature is lower than a first temperature threshold, entering a starting heating stage, and controlling a heating unit to heat at a first power; when the screen temperature reaches or is higher than a second temperature threshold and is lower than the first temperature threshold, entering a predictive temperature control stage, and performing first predictive control; the first predictive control is based on the screen temperature, the ambient temperature and thermal characteristic parameters of the screen, the future change trend of the screen temperature is predicted through a dynamic thermal inertia model, and the heating power is dynamically adjusted according to the prediction result; when the screen temperature approaches the first temperature threshold, entering a steady-state adjustment stage, and adopting a proportional-integral-derivative (PID) control algorithm with self-adaptive adjustment parameters to control the temperature.
