An embodiment of the present invention provides a coolant temperature display method and device, the method comprising: if the first calorific value of the engine combustion into the coolant is greater than the second calorific value of the coolant exported through the radiator, and the thermostat is closed , then calculate the first time required for the coolant at the inlet of the thermostat to rise from the current temperature to the first set temperature; display the current temperature, the first set temperature and the first time on the display device; if the first calorific value If it is greater than the second calorific value and the thermostat is fully open, then the second time period required for the coolant at the inlet of the thermostat to rise from the current temperature to the second set temperature is calculated. The driver can directly know the future operating state of the cooling system without experience, and provides strong support for the driver to perform effective and safe driving operations.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of automobiles, in particular to a method and device for displaying coolant temperature. Background technique [0002] A car's cooling system is designed to keep the system from getting too hot and too cold. When the temperature of the coolant rises too fast, too slow, approaches or exceeds the limit, the driver needs to judge and predict based on experience. In the actual operation of the whole vehicle, predicting how long the current operating condition will last until the coolant target value is reached will help the driver to predict and eliminate anxiety, and it will also help to give the driver timely warning when a fault occurs. Reminder to better control the use of the car [0003] At present, in the prior art, the temperature of the coolant is mostly displayed on the instrument in the form of a pointer, a column or a numerical value, and the color of the scale area or the col...
