Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a vehicle speed display method according to an embodiment of the present invention, where the embodiment is applicable to displaying a vehicle speed of a vehicle at a current time to reduce fluctuation of numbers or pointers for displaying the vehicle speed, and the method may be implemented by a vehicle speed display device, which may be implemented in hardware and/or software and may be integrated in the vehicle, and referring to fig. 1, the method may include the following steps:
and S110, acquiring a vehicle speed signal value at the current moment and a vehicle speed signal value at the previous moment.
The vehicle speed signal value of this embodiment is exemplified by a CAN (Controller Area Network) signal value. The CAN signal values CAN be acquired in real time in the running process of the vehicle, and the CAN signal values at the current moment and the previous moment are acquired from the CAN signal values. In order to reduce the interference of other signals to the CAN signal values, the obtained CAN signal values may be filtered, and the filtering manner may be selected according to the situation, for example, a first-order low-pass filtering manner may be adopted to filter the CAN signal values at the current time and the last time.
S120, passing formula VN＝k1*(Vn-Vn-1)+VnAnd obtaining the vehicle speed value at the current moment.
Wherein, VNIs the value of vehicle speed, V, at the present momentnIs the value of the vehicle speed signal at the current moment, Vn-1K1 is a positive number greater than 0 and less than 1, and n is a natural number greater than or equal to 2. It CAN be understood that the CAN signal value is easy to jitter or jump under the condition of rapid acceleration or rapid deceleration, and if the value is directly displayed to the user, the appearance of the user is affected. In order to reduce jitter or jump, the present embodiment provides a coefficient k1, and the size of k1 may be set according to the characteristics of the vehicle, for example, when k1 is equal to 0.1, the difference between the CAN signal values at the current time and the last time is reduced to one tenth of the original value, which effectively reduces jitter and sudden change of the CAN signal values. According to the embodiment, the CAN signal value CAN be converted into the vehicle speed value at the current moment through the formula, so that a basis is provided for subsequently determining the actual vehicle speed value of the vehicle at the current moment.
It should be noted that V in the above formula is used when filtering CAN signal values at the current time and the last timenAnd Vn-1The CAN signal values after the current time and the last time are filtered respectively.
And S130, determining the actual vehicle speed value at the current moment and displaying the actual vehicle speed value according to the vehicle speed value at the current moment and the vehicle speed display value at the current moment.
In order to display the real vehicle speed, the present embodiment determines the actual vehicle speed value at the current time according to the vehicle speed value obtained by the conversion and the vehicle speed display value, and displays the actual vehicle speed value. Optionally, a difference between the vehicle speed value obtained by the conversion and the vehicle speed display value may be determined, when an absolute value of the difference is smaller than a set threshold, the vehicle speed display value at the current moment may be used as the actual vehicle speed value at the current moment, and the display is kept unchanged, and when the absolute value of the difference is larger than the set threshold, the actual vehicle speed value at the current moment may be determined according to the actual vehicle speed value at the previous moment and the set threshold, so that the finally displayed actual vehicle speed value tends to be stable, and the user's impression is improved.
The embodiment one of the invention provides a vehicle speed display method, which comprises the steps of obtaining a vehicle speed signal value at the current moment and a vehicle speed signal value at the previous moment; by the formula VN＝k1*(Vn-Vn-1)+VnObtaining the vehicle speed value at the current moment, wherein VNIs the value of vehicle speed, V, at the present momentnIs the value of the vehicle speed signal at the current moment, Vn-1The vehicle speed signal value at the previous moment is k1, which is a positive number greater than 0 and less than 1, and n is a natural number greater than or equal to 2; and determining the actual vehicle speed value at the current moment and displaying the actual vehicle speed value according to the vehicle speed value at the current moment and the vehicle speed display value at the current moment. The scheme reduces the difference value between the vehicle speed signal value at the current moment and the vehicle speed signal value at the previous moment to be k1, wherein k1 is more than 0 and less than 1, thereby effectively reducing the jitter or jump of the vehicle speed signal value, reducing the fluctuation of numbers or pointers when displaying the vehicle speed, and improving the impression of users.
Example two
Fig. 2 is a flowchart of a vehicle speed display method according to a second embodiment of the present invention, where the present embodiment is optimized based on the foregoing embodiment, and referring to fig. 2, the method may include the following steps:
and S210, acquiring a vehicle speed signal value at the current moment and a vehicle speed signal value at the previous moment.
S220, passing formula VN＝k1*(Vn-Vn-1)+VnAnd obtaining the vehicle speed value at the current moment.
Wherein, VNIs the value of vehicle speed, V, at the present momentnIs the value of the vehicle speed signal at the current moment, Vn-1K1 is a positive number greater than 0 and less than 1, and n is a natural number greater than or equal to 2.
And S230, determining the difference value between the vehicle speed value and the vehicle speed display value.
Alternatively, the vehicle speed value obtained by the conversion may be compared with the vehicle speed display value to determine the difference Z ═ VN-VDWherein V isDZ is the difference between the vehicle speed value and the vehicle speed display value.
And S240, whether the absolute value of the difference is smaller than or equal to the absolute value of the set threshold or not is judged, if yes, S250 is executed, and if not, S260 is executed.
The size of the set threshold can be set according to actual conditions, and optionally, can be between 0 and 2, and of course, can also be greater than 2. In this embodiment, the threshold is set to 0.01 as an example. Specifically, when the Z is less than or equal to 0.01, the vehicle speed value at the current moment is used as and displayed on the actual vehicle speed value at the current moment, so that the problem that the vehicle speed display value infinitely approaches to the vehicle speed value but cannot be equal to the vehicle speed value due to the fact that the vehicle speed display value is close to the vehicle speed value is solved. When Z is greater than 0.01, the actual vehicle speed value at the current time needs to be determined according to the set threshold and the actual vehicle speed value at the previous time.
And S250, taking the vehicle speed value at the current moment as the actual vehicle speed value at the current moment.
And S260, determining the actual vehicle speed value at the current moment according to the actual vehicle speed value at the previous moment and the set threshold value.
Optionally, when the absolute value of the difference is greater than the absolute value of the set threshold, the magnitude of the difference needs to be further considered, for example, if the difference is greater than 0, the sum of the actual vehicle speed value at the previous time and the set threshold is taken as the actual vehicle speed value at the current time; and if the difference value is smaller than 0, taking the difference between the actual vehicle speed value at the previous moment and the set threshold value as the actual vehicle speed value at the current moment.
Illustratively, when Z is greater than 0, by formula VD(n)＝VD(n-1)+0.01 to obtain the actual speed value at the current time, when Z is less than 0, the formula V is usedD(n)＝VD(n-1)0.01 obtaining the actual vehicle speed value at the current moment, wherein VD(n)Is the value of vehicle speed, V, at the present momentD(n-1)The actual vehicle speed value at the previous time is 0.01, which is a set threshold value.
And S270, displaying the actual vehicle speed value in a numerical or pointer mode.
On the basis of the embodiment, when sudden acceleration or sudden deceleration occurs or the CAN signal value rapidly changes due to interference and other reasons to cause jump or jitter on vehicle speed display, the jitter CAN be weakened to be k1 times of the original jitter by the scheme, wherein k1 is more than 0 and less than 1; setting a threshold value, for example 0.01, for each change of the number or the pointer in the process that the vehicle speed display value approaches to the vehicle speed value, so that the change of the number or the pointer tends to be smooth; when the vehicle speed display value is close to the vehicle speed value, for example, less than 0.01, the vehicle speed display value is directly used as the actual vehicle speed value to be displayed, and therefore the real vehicle speed is reflected.
