Problems solved by technology

[0003] When the vehicle is running, the driver will accelerate or decelerate, and the change of acceleration and deceleration will cause the liquid level of the urea tank to fluctuate, so the actual liquid level of the urea tank detected by the sensor is inaccurate
In addition, when the liquid level of the urea tank fluctuates, due to the difference in the length and width of the urea tank matched with the vehicle, the difference in the installation position of the sensor, and the actual current urea liquid level, the urea liquid level sensor will also be detected There is a big difference in the remaining liquid level of the urea tank
The frequent fluctuation of urea liquid level leads to inaccurate percentage of remaining urea liquid level displayed on the instrument panel, thus affecting the driving experience of the driver

Abstract

The invention discloses a urea liquid level detection method and device, a storage medium and electronic equipment. The method comprises the following steps: determining a current vehicle state and anoriginal urea liquid level value; acquiring the acceleration of the current vehicle, the current liquid level of an urea tank and the position parameters of an urea liquid level sensor according to the current vehicle state as the driving state; and determining the urea liquid level value of the current vehicle according to the acceleration, the current liquid level of the urea box and the position parameters of the urea liquid level sensor. Therefore, by adopting the method, the fluctuation of the urea liquid level of an instrument can be reduced, and the display accuracy is improved.

Description

technical field [0001] The invention relates to the field of automotive electronic control, in particular to a urea liquid level detection method, device, storage medium and electronic equipment. Background technique [0002] With the rapid development of society, cars have become an indispensable part of every household. Automotive urea is a liquid used in selective catalytic reduction technology to reduce nitrogen oxides in diesel vehicle exhaust. After the car is started, the trip computer collects data from the urea level sensor and displays the urea level on the dashboard in real time. [0003] When the vehicle is running, the driver will accelerate or decelerate, and the change of acceleration and deceleration will cause the liquid level of the urea tank to fluctuate, so the actual liquid level of the urea tank detected by the sensor is inaccurate. In addition, when the liquid level of the urea tank fluctuates, due to the difference in the length and width of the ure...
