Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a method for improving indication stability of a fuel gauge, including:
and S1, acquiring the acceleration data monitored by the inertial measurement unit in real time. Further, the inertia measurement unit is a 6-axis inertia measurement unit.
It should be noted that, in step S1, acceleration data monitored by the inertia measurement unit of the entire vehicle configuration is acquired. An inertial measurement unit is a device that measures the three-axis attitude angle (or angular rate) and acceleration of an object. Generally, an IMU includes three single-axis accelerometers and three single-axis gyroscopes, the accelerometers detect acceleration signals of an object in three independent axes of a carrier coordinate system, and the gyroscopes detect angular velocity signals of the carrier relative to a navigation coordinate system, and measure angular velocity and acceleration of the object in three-dimensional space, and then solve the attitude of the object.
S2, recording the target time period when the vehicle is in a rapid acceleration and deceleration running state; and when the acceleration of the vehicle is judged to be larger than a preset threshold value according to the acceleration data, the vehicle is judged to be in a rapid acceleration and deceleration running state.
In the embodiment of the present invention, further, when it is determined that the acceleration of the vehicle is greater than the preset threshold according to the acceleration data, it is determined that the vehicle is in a rapid acceleration and deceleration running state, specifically:
acquiring an acceleration absolute value of the vehicle in unit time according to the acceleration data;
and when the absolute value of the acceleration of the vehicle in unit time is judged to be larger than a preset threshold value, judging that the vehicle is in a rapid acceleration and deceleration running state.
In the embodiment of the present invention, step S2 is to calculate the time periods during which the vehicle is accelerating rapidly and decelerating rapidly from the acceleration data, and record these time periods.
And S3, filtering the acquired resistance value of the oil quantity indicating system during the target time period.
The fuel quantity indicating system calculates and converts the resistance value output by the fuel sensor into the display value of the fuel gauge, and the embodiment of the invention only extracts the resistance values of the vehicle in a static state, a constant speed state and a state with small acceleration and deceleration fluctuation on a normal road surface for calculation by calculating the time periods of rapid acceleration and rapid deceleration of the vehicle and filtering the resistance values in the time periods, thereby enabling the fuel gauge to be displayed more stably and accurately.

at present, the principle of fuel gauge display of a motorcycle is basically judged according to the resistance value output by an oil sensor in an oil tank. The change of the fuel level in the fuel tank causes the change of a floating ball of the fuel sensor, thereby causing the change of the output resistance value. However, during the rapid acceleration and rapid deceleration of the vehicle, the liquid level in the oil tank will be inclined sharply, which causes the output resistance value to be unstable, and finally causes the fuel gauge to display inaccurately and fluctuate greatly.
As shown in fig. 2-3, during rapid deceleration, the liquid level tilts forward, which drives the float to float upward, causing a drastic change in output resistance.
As shown in fig. 4, in the embodiment of the present invention, the driving state of the vehicle can be determined by using data of a 6-axis Inertial Measurement Unit (IMU) configured in the entire vehicle, the resistance values in the time periods of rapid acceleration and rapid deceleration are filtered, and only the resistance value with small acceleration and deceleration fluctuation (and the constant speed state) on the normal road surface is extracted for calculation, so that the fuel gauge is displayed more stably and accurately.
