[0002] With the popularization of electrification and intelligentization of vehicles, more and more vehicles use full-liquid crystal display instruments to display state parameters such as vehicle speed, rotating speed of components in the vehicle, and battery power in the vehicle. Unlike traditional mechanical pointer instruments, the full-liquid crystal display instrument realizes the movement of the pointer by drawing points and lines on the screen to indicate the current state parameters of the vehicle.

[0050] The specific embodiments of the present application have been shown through the above-described drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the present application concept in any way, but to illustrate the present application concept to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0051] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. In addition, although the disclosure in the present application is introduced according to one or more exemplary examples, it should be understood that each aspect of these disclosures can also constitute a complete embodiment independently.

[0052] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the subsequently described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0053] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not have to be limited to those components clearly listed, but can include other components not clearly listed or inherent to these products or devices.

[0054] The term "module" used in the embodiments of the present application refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or a combination of hardware or / and software code capable of performing the functions associated with that element.

[0055] It should be noted that the user information (including but not limited to user equipment information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards, and provide corresponding operation portal for user to choose authorization or refusal.

[0056] With the popularization of electrification and intelligence of vehicles, more and more vehicles use full-liquid crystal display instruments to display the speed of the vehicle, the rotating speed of the components in the vehicle, the battery power and other state parameters in the vehicle. Unlike traditional mechanical pointer instruments, the full-liquid crystal display instrument realizes the movement of the pointer by drawing points and lines on the screen to indicate the current state parameters of the vehicle.

[0057] The instrument undertakes the interactive work of man-machine information, therefore, the display effect of the pointer in the instrument needs to be smooth and continuous to display the state parameters, avoiding the display of the pointer from being jerky, flickering and other situations that affect the vehicle driver to accurately obtain information.

[0058] In the exemplary technology, a control method for constructing a pointer motion model based on the idea of segmented control is constructed, which sets the acceleration point and the deceleration point in the pointer movement process by task, sets the acceleration segment, the constant speed segment and the deceleration segment of the pointer motion, and sets various critical conditions to adapt to different sections of the vehicle.

[0059] The present inventors find that the segmented control needs to allocate higher computing resources to the vehicle by setting the critical conditions, the acceleration segment, the constant speed segment and the deceleration segment to calculate the position of the pointer, and the vehicle needs to be configured with higher computing resources to realize the continuous display of the pointer, that is, the generality of the continuous display mode of the pointer in the existing instrument is low.

[0060] The present inventors therefore think that the state parameter control curve can be determined by the first state parameter currently collected and the second state parameter collected last time, and the state parameter control curve can be used to control the pointer to display the state parameters of the vehicle smoothly and continuously in the current display period, which simplifies the calculation process required for the continuous display of the pointer, and the vehicle needs less computing resources to realize the continuous display of the pointer, without the need for the vehicle to be configured with higher computing resources, that is, the low-configuration vehicle can also realize the continuous display of the pointer, improving the generality of the continuous display mode of the pointer.

[0061] Reference Figure 1 , Figure 1This is a schematic diagram illustrating an application scenario of the vehicle instrument display method of this application. The vehicle acquires the currently collected first state parameter and the previously collected second state parameter V, and determines the current display cycle of the instrument 100 in the vehicle based on the acquisition interval between the first state parameter and the second state parameter. The vehicle determines the state parameter control curve of the vehicle within the current display cycle based on the first state parameter and the second state parameter. For example, the first state parameter is the first vehicle speed V. n+1 And the second state parameter is the second vehicle speed V. n . Reference Figure 2 , Figure 2 This is the vehicle speed control curve, currently displayed with a period of t. n To t n+1 The pointer 110 in the instrument cluster 100 has a pointer display period, for example, the pointer position is refreshed every 1ms, so the pointer display period is 1ms. The vehicle has multiple pointer display periods in the current display period. The vehicle determines the time period corresponding to each pointer display period within the current display period on the vehicle speed control curve, and thus controls the pointer 110 sequentially according to the time order of each pointer display period within the current display period, so that the pointer points to the vehicle speed corresponding to each target period in the instrument cluster 100. For example, refer to... Figure 1 , t n The vehicle speed at time V n t n+0.2 The vehicle speed at time V n+0.2 t n+0.4 The vehicle speed at time V n+0.4 t n+0.6 The vehicle speed at time V n+0.6 t n+0.8 The vehicle speed at time V n+0.8 t n+1 The vehicle speed at time V n+1 .

[0062] The following is passed Figure 1 as well as Figure 2 The technical solutions shown in this application will be described in detail with reference to specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other, and the same or similar content will not be described again in different embodiments.

[0063] Reference Figure 3 , Figure 3 This is a flowchart illustrating the vehicle instrument display method provided in the embodiments of this application. Figure 1 Vehicle instrument panel display methods include:

[0064] Step S301, obtaining the first state parameter of the vehicle collected currently and the second state parameter of the vehicle collected last time, and determining the current display period of the pointer in the instrument in the vehicle according to the collection interval time length between the first state parameter and the second state parameter.

[0065] In the embodiment, the vehicle is provided with an instrument, which is a liquid crystal display instrument. The liquid crystal display instrument is provided with a display screen. A virtual dial and a pointer are arranged in the display screen. A plurality of state parameter scales are arranged on the virtual dial. The state parameter is, for example, vehicle speed. The state parameter scale is, for example, 1 km / h. The pointer moves by one state parameter scale, which indicates that the vehicle speed changes by 1 km / h.

[0066] The vehicle collects the state parameter of the vehicle at regular intervals. The collected state parameter is reported in the form of a message. The vehicle obtains the state parameter collected currently from the current message. The state parameter is defined as the first state parameter. The vehicle obtains the state parameter collected last time from the last message. The state parameter collected last time is defined as the second state parameter. The first state parameter and the second state parameter can be the vehicle speed, the engine speed in the vehicle, the battery capacity in the vehicle, and the like. The types of the first state parameter and the second state parameter are the same. For example, the first state parameter is the vehicle speed, and the second state parameter is also the vehicle speed.

[0067] The vehicle determines the current display period of the instrument in the vehicle based on the collection interval time length between the first state parameter and the second state parameter. For example, the vehicle collects the state parameter at a preset interval. The preset interval is the collection interval time length. The time length of the current display period is the collection interval time length. The starting time point of the current time period is the ending time point of the last collection interval time length.

[0068] Step S302, determining the state parameter control curve of the vehicle in the current display period according to the first state parameter and the second state parameter.

[0069] The device determines the state parameter control curve of the vehicle in the current display period based on the first state parameter and the second state parameter after determining the first state parameter and the second state parameter. For example, the vehicle is provided with a relational expression corresponding to the state parameter. The first state parameter and the second state parameter are substituted into the relational expression, and the state parameter control curve is obtained. For details, refer to Figure 2 The state parameter is the vehicle speed, Figure 2 The vehicle speed collected currently and the vehicle speed collected last time are input into the relational expression to obtain the vehicle speed control curve. For example, t n t n+1 is the last display period. The vehicle speed displayed in the instrument in the vehicle changes from V n to V n+1 ; tn+1 t n+2 is the current display period, the speed displayed in the instrument in the vehicle from V n+1 is displayed to V n+2 It should be noted that the instrument displays the second state parameter collected last time at the start time point of the current display period, and displays the first state parameter collected at the end time point of the current period, so the collection interval time cannot be too long, that is, the collection interval time is less than the preset time, for example, the collection interval time is 100 ms.

[0070] In step S303, the target state parameter corresponding to each target period contained in the current display period in the state parameter control curve is determined, and the target period is used to indicate the pointer display period of the pointer in the instrument.

[0071] After the vehicle obtains the state parameter control curve, the target state parameter corresponding to each target period contained in the current display period is determined, and the target period is used to indicate the pointer display period corresponding to the pointer in the instrument. The pointer display period refers to the period of movement of the pointer once, for example, the pointer display period is 1 ms. The time length of the current display period is greater than the time length corresponding to the pointer display period, so the pointer needs to move multiple times in the current display period, for example, the time length corresponding to the current display period is 100 ms, so the current display period contains 100 pointer display periods, and thus the state parameter corresponding to each pointer display period needs to be determined based on the state parameter control curve, and the state parameter corresponding to the pointer display period is defined as the target state parameter, and the types of the first state parameter, the second state parameter and the target state parameter are the same.

[0072] For example, after the vehicle obtains the state parameter control curve, the state parameter control curve is discretely processed, and the discrete processing satisfies T=t n+1 -t n =k·T z , where T is the time length of the current display period, t n is the start time point of the current display period, t n+1 is the end time point of the current display period, k is the number of pointer display periods contained in the current display period, and T z is the time length of the pointer display period. For example, the speed control curve is obtained, and the serialized speed value Y={y i} i＝1…k is obtained by discretely processing the speed control curve, for example, y1 is the target speed of the first pointer display period in the current display period, y2 is the target speed of the second pointer display period in the current display period, and y3 is the target speed of the third pointer display period in the current display period.

[0073] Step S304: According to the time sequence of each target cycle within the current display cycle, control the pointer sequentially to point to the target status parameter corresponding to each target cycle in the instrument.

[0074] After obtaining the target status parameters, the vehicle controls the pointers in the instrument panel to point to the target status parameters corresponding to each target cycle in the time sequence of each target cycle within the current display cycle.

[0075] For example, if the target state parameter is the target vehicle speed, then the target vehicle speed Y = {y} in each target cycle. i} i＝1…k For example, y1 is the target vehicle speed in the first pointer display cycle within the current display cycle, y2 is the target vehicle speed in the second pointer display cycle within the current display cycle, y3 is the target vehicle speed in the third pointer display cycle within the current display cycle, ..., y k This refers to the target vehicle speed in the k-th pointer display cycle within the current display period. Therefore, when the current time point is in the first pointer display cycle, the control pointer points to the target vehicle speed y1 in the instrument panel; when the current time point is in the second pointer display cycle, the control pointer points to the target vehicle speed y2 in the instrument panel; when the current time point is in the third pointer display cycle, the control pointer points to the target vehicle speed y3 in the instrument panel; and so on. When the current time point is in the k-th pointer display cycle, the control pointer points to the target vehicle speed y1 in the instrument panel. k .

[0076] In this embodiment, the vehicle obtains a state parameter control curve for the current display cycle using the currently collected first state parameters and the previously collected second state parameters. The target state parameters for each pointer display cycle within the current display cycle are determined from this control curve. Then, following the chronological order of the pointer display cycles within the current display cycle, the pointers are sequentially controlled to point to the target state parameters corresponding to each pointer display cycle, thus achieving a continuous and smooth display of the vehicle's state parameters. In this application, the state parameter control curve is determined using the currently collected first state parameters and the previously collected second state parameters. This curve allows for smooth and continuous display of the vehicle's state parameters within the current display cycle, simplifying the computational process required for continuous pointer display. The vehicle requires fewer computational resources to achieve continuous pointer display, eliminating the need for high-end vehicle configurations. This means even low-configuration vehicles can achieve continuous pointer display, improving the versatility of the continuous pointer display method.

[0077] Reference Figure 4 , Figure 4 This is a flowchart illustrating the vehicle instrument display method of this application. Figure 2 ,based on Figure 3In the illustrated embodiment, step S302 comprises:

[0078] Step S401, determining the transfer function corresponding to the second order damping control.

[0079] In the present embodiment, the vehicle simulates the smooth and continuous movement of the pointer in the control instrument frame by frame. To this end, the vehicle determines the transfer function corresponding to the second order damping control, which refers to the damping control in an automatic control system for a system that can be described by a second order linear ordinary differential equation. The closed-loop transfer function of the second order damping control system is:

[0080]

[0081] where ω n and ζ are characteristic parameters of the second order system, ω n is the undamped natural oscillation frequency, and ζ is the damping ratio. When the value of ζ is in the range of ζ>1, the system is in an over-damped state, there are two negative real roots, and the poles are all in the left half of the complex plane, the system is stable, and the unit step response curve of the system is monotonously rising and does not exist overshoot. In this method, the over-damped state (ζ>1) of the system is simulated by mechanical damping, and the values of ζ and ω n are determined according to the specific scene, condition, and response effect by combining the parameter formula of the second order system model. For example, ζ=1.5, ω n =0.5, and the closed-loop transfer function of the second order simulation damping system is set as:

[0082]

[0083] Step S402, determining the state parameter control curve of the vehicle in the current display period based on the first state parameter, the second state parameter, and the transfer function.

[0084] The vehicle can determine the state parameter control curve of the vehicle in the current display period based on the first state parameter, the second state parameter, and the transfer function. For example, referring to Figure 5 , G(s) is the above-mentioned closed-loop transfer function, the first state parameter and the second state parameter are vehicle speeds, and the two vehicle speeds are input into G(s) to obtain a vehicle speed control curve y. The vehicle speed control curve y is discretely processed to obtain Y={y i} i＝1…k .

[0085] The pointer moving control method based on the second-order damping control provided in the embodiment is designed based on the automatic control principle and the original mechanical pointer damping characteristics, and the virtual pointer control method with good human-computer interaction experience is simulated, so that the sensory experience of the driver is greatly improved, the vehicle information is effectively conveyed, and a feasible scheme is provided for the intelligentization and humanization of the automobile instrument.

[0086] In the embodiment, the mechanical pointer rotation effect is simulated based on the damping concept of the second-order system, the problems of tearing and jerk of the pointer picture caused by discontinuity and mutation during the rotation of the digital pointer are solved, the smooth pointer moving effect is improved, the human-computer interaction feeling is improved, and the method can be applied to the speed dial pointer, the speed dial pointer, the electric quantity dial pointer or the liquid crystal instrument pointer control scene with a dial in a vehicle instrument.

[0087] Reference Figure 6 , Figure 6 The flowchart of the vehicle instrument display method Figure 3 , based on the embodiments shown in Figure 3 or Figure 4 , step S304 comprises:

[0088] Step S601, determining the first pointing position of the pointer in the current target period, and obtaining the state parameter scale of the dial in the instrument.

[0089] In the embodiment, the control of the pointer in each pointer display period of the current display period is described, and the control mode of the pointer in each pointer display period is the same, and the control of the pointer in one pointer display period is described below.

[0090] The vehicle first determines the pointing position of the pointer in the current target period, which is defined as the first pointing position, and obtains the state parameter scale of the dial in the instrument. For example, the state parameter is the vehicle speed, and each movement of the pointer in the dial represents a change of 1km / h in the vehicle speed.

[0091] Step S602, determining the second pointing position of the pointer in the next target period according to the target state parameter corresponding to the next target period, the first pointing position and the state parameter scale.

[0092] The device determines the second pointing position of the pointer in the next target period based on the target state parameter corresponding to the next target period, the first pointing position and the state parameter scale. For example, the target state parameter corresponding to the next target period is 50 km / h, the first pointing position of the pointer in the target period indicates 49 km / h, and one state parameter scale is 1 km / h. The second pointing position is the position of the pointer pointing to 50 km / h on the surface, that is, the pointer needs to move one state parameter scale from the current target period to the next target period.

[0093] In step S603, in the case that the current time point reaches the start time point of the next target period, the control pointer moves to the second pointing position, so that the pointer points to the target state parameter corresponding to the next target period.

[0094] In the case that the current time period reaches the start time point of the next target period, the device controls the specified movement to the second pointing position, so that the pointer points to the target state parameter corresponding to the next target period.

[0095] In this embodiment, the vehicle determines the second pointing position of the pointer in the next target period based on the first pointing position of the pointer in the current target period, the running scale parameter of the dial in the instrument and the target state parameter of the next target period, so as to accurately control the pointing of the pointer in the next target period.

[0096] Reference Figure 7 , Figure 7 The flowchart of the vehicle instrument display method of the present application Figure 4 , based on Figure 6 The embodiment shown in step S603 comprises:

[0097] In step S701, the moving speed of the pointer in the dial is determined according to the first pointing position, the second pointing position and the time length corresponding to the target period.

[0098] In this embodiment, the vehicle determines the moving speed of the pointer in the dial based on the first pointing position, the second pointing position and the time length of the target period. For example, the time length corresponding to the display period of the pointer is 2 ms, and there are 2 state parameter scales between the first pointing position and the second pointing position. Therefore, the moving speed of the pointer in the dial is one state parameter scale per millisecond.

[0099] In step S702, the pointer is controlled to move from the first pointing position to the second pointing position according to the moving speed.

[0100] After the vehicle determines the moving speed of the pointer in the dial, and the current time point reaches the start time point of the next target period, the vehicle controls the pointer to move from the first pointing position to the second pointing position according to the moving speed. Exemplarily, during the movement of the pointer from the first pointing position to the second pointing position, the speed of the pointer is fluctuated around the moving speed, that is, the speed of the pointer is variable.

[0101] Further, the device determines the number of state parameter scales between the second pointing position and the first pointing position, and if the number is greater than a preset number, the vehicle determines the moving speed of the pointer in the dial based on the first pointing position, the second pointing position and the time length corresponding to the target period, that is, in the case that the number of state parameter scales is large, the user can obviously perceive the movement of the pointer, and thus it is necessary to use the moving speed to smoothly move the pointer from the first pointing position to the second pointing position. In the case that the number is less than or equal to the preset number, the amplitude of the movement of the pointer is small, and thus it is not necessary to specially determine the moving speed of the pointer.

[0102] In the embodiment, the device determines the moving speed of the pointer in the dial based on the first pointing position, the second pointing position and the time length corresponding to the target period, so as to control the pointer to continuously and smoothly move from the first pointing position to the second pointing position according to the moving speed.

[0103] In an embodiment, the vehicle acquires the screen refresh rate of the instrument, sets the pointer display period corresponding to the pointer based on the screen refresh rate, and the period time length corresponding to the pointer display period is greater than or equal to the refresh interval time length corresponding to the screen refresh rate.
