[0029] To make the objectives, technical solutions and advantages of the present invention clearer, the following will refer to the drawings in the embodiments of the present invention and clearly and completely describe the technical solutions of the present invention through the embodiments. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the basic concepts disclosed and prompted by the embodiments of the present invention, all other embodiments obtained by those skilled in the art belong to the scope of protection of the present invention.

[0030] Embodiment 1

[0031] Figure 1FIG. 0 is a schematic structural diagram of an instrument control system of an electric vehicle provided in Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the situation where a user monitors the power state of an electric vehicle in real time through an instrument display. This system can be implemented in a software and / or hardware manner and can be integrated into devices such as electric vehicles.

[0032] As Figure 1 shown, the instrument control system of the electric vehicle provided in this embodiment includes: an energy controller 100 and an instrument display component 200; the energy controller 100 is configured to collect kinetic energy signals generated during the driving of the electric vehicle according to the driving state of the electric vehicle, convert the kinetic energy signals into feedback power signals, and determine their feedback power parameters; the instrument display component 200 is electrically connected to the energy controller 100, and is configured to receive the feedback power parameters output by the energy controller 100 and display the feedback power parameters, and the feedback power parameters at least include a charging current.

[0033] The energy controller 100 collects kinetic energy signals generated during driving states such as braking and coasting of the electric vehicle in real time, converts the collected kinetic energy signals into feedback power signals, and realizes the recycling of energy. The energy controller 100 determines the corresponding feedback power parameters according to the converted feedback power signals, and sends the feedback power parameters to the instrument display component 200. The instrument display component 200 displays the feedback power parameters sent by the energy controller 100 received in real time on its display screen. The feedback power parameters at least include a charging current. The larger the charging current, the greater the energy feedback strength, that is, the more the charging amount. The intuitive display of the feedback power parameters facilitates the user to monitor the power state of the whole vehicle in real time and improves the user experience.

[0034] Among them, the content, display method, and display position of the feedback power parameters are not limited and can be set according to market demands and user selections. For example, the feedback power parameters may include the charging current and charging amount generated due to energy feedback during the braking process of the electric vehicle; the charging current can be reflected by setting current columns of different colors and / or different lengths on the instrument display component, and the darker the color and / or the longer the current column length, the greater the energy feedback strength; the charging amount can be displayed in digital form on the instrument display component, which can be the charging amount of a single ride and is automatically cleared after the electric vehicle is turned off; according to the user's selection requirements, the feedback power parameters can be continuously displayed during driving or the display can be turned off at any time; the display position of the feedback power parameters can be adjusted according to actual situations such as the instrument style, and can be below the display screen of the instrument display component or on the left and right sides of the display screen. The real-time display of the feedback power parameters by the instrument display component 200 facilitates the user to master the relationship between the driving state of the electric vehicle and the charging amount, and gradually enables the user to form a good habit of energy-saving riding, such as reducing braking and increasing coasting on complex roads to increase the charging amount of energy feedback.

[0035] For example Figure 1 Optionally, it further includes: a memory 300, in which a charging current database is stored. The charging current database includes a first charging current range to an Mth charging current range, and the charging current value of the ith charging current range is less than that of the (i + 1)th charging current range, where 1 ≤ i ≤ M.

[0036] For example Figure 1 As shown, the instrument control system of the electric vehicle provided in this embodiment further includes a memory 300. A charging current database is stored in the memory 300. The charging current database includes M charging current ranges, and the charging current value of the ith charging current range is less than that of the (i + 1)th charging current range, where 1 ≤ i ≤ M. The energy controller 100 converts the kinetic energy signal generated during the driving of the electric vehicle into a feedback power signal, determines the corresponding feedback power parameters, and sends the feedback power parameters to the instrument display component 200. The instrument display component 200 compares the charging current in the received feedback power parameters with the charging current ranges in the memory 300. When it detects that the charging current is in the ith charging current range, it can display the charging current color and / or current bars of different lengths corresponding to the ith charging current range on its display screen to reflect the corresponding energy feedback strength. For the first charging current range to the Mth charging current range, the corresponding charging current values increase in sequence, indicating that the energy feedback strength increases in sequence. For example, it can be set that for the first charging current range to the Mth charging current range, the color of the charging current displayed on the display screen of the instrument display component 200 changes from light to dark, and / or the length of the current bar changes from short to long, to indicate the increase in energy feedback strength. The display method of the charging current intensity is not limited. In other embodiments, the charging current strength can also be represented by different numbers of vertical current bars. The more the number of vertical current bars, the stronger the charging current. The real-time and intuitive display of the charging current facilitates the user to monitor the power state of the whole vehicle and improves the user experience.

[0037] For example Figure 1 and Figure 2 Optionally, the instrument display component 200 includes a driving circuit 210 and a charging current display area 220. The charging current display area 220 includes a first display partition to an Mth display partition arranged in sequence along a first direction. The display partition 221 includes at least one display element; the driving circuit 210 is electrically connected to the energy controller 100 and the memory 300 respectively, and is used to obtain the charging current through the energy controller 100, and when it detects that the charging current is in the ith charging current range, drive the display elements of the first display partition to the ith display partition to emit light synchronously.

[0038] For example Figure 1As shown, the instrument display component 200 includes a drive circuit 210 and a charging current display area 220. The charging current display area 220 includes a first display partition to an M-th display partition arranged in sequence along a first direction. The display partition 221 includes at least one display element. For details, see Figure 2 . The first display partition to the M-th display partition in the charging current display area 220 correspond to the first charging current range to the M-th charging current range in the memory 300. The drive circuit 210 compares the charging current in the feedback power parameters sent by the received energy controller 100 with the charging current ranges in the memory 300. When it detects that the charging current is in the i-th charging current range, the drive circuit 210 drives the display elements of the first display partition to the i-th display partition in the charging current display area 220 to emit light synchronously ( Figure 2 shown in black for emitting light), to represent the charging current of the corresponding intensity, and thus reflect the corresponding energy feedback strength. The larger the i of the display partition 221 that emits light in the charging current display area 220, the larger the charging current value and the stronger the energy feedback strength.

[0039] Among them, the number and light-emitting color of the display elements are not limited. One display partition 221 can correspond to one light-emitting element, or one display partition 221 can correspond to multiple light-emitting elements. The light-emitting colors of the display elements corresponding to different display partitions 221 can be the same or different, as long as the energy feedback strength information can be transmitted to the user through the light-emitting color, number, etc. of the display elements of the display partition 221. The first direction is not limited and can be set according to the actual situation. For example, the first direction can be the horizontal direction or the vertical direction. The position of the charging current display area 220 and the shape of the display partition 221 are not limited. For example, the charging current display area 220 can be set on the left side or the lower right corner of the display screen, and the display partition 221 can be rectangular, circular, etc. The real-time and intuitive display of the charging current facilitates the user to master the power state of the whole vehicle, helps the user form the habit of energy-saving cycling, and improves the user experience.

[0040] For example Figure 1 and Figure 2 , optionally, the feedback power parameter further includes the charging amount; the instrument display component 200 further includes a charging amount digital display area 230, and the drive circuit 210 drives the charging amount digital display area 230 to perform different digital displays; the drive circuit 210 is used to obtain the charging amount through the energy controller 100 and drive the charging amount digital display area 230 to perform charging amount digital display.

[0041] For example Figure 1As shown, the instrument display component 200 further includes a charge quantity digital display area 230. The feedback power parameter sent by the energy controller 100 also includes the charge quantity. The driving circuit 210 obtains the charge quantity sent by the energy controller 100 and drives the charge quantity digital display area 230 to display the corresponding charge quantity value, such as 8.88 Ah shown in Figure 2. The digital display of the charge quantity digital display area 230 can represent the cumulative charge quantity of a single ride. The charge quantity digital display area 230 can be set at the upper left or lower part of the display screen, and the specific position is not limited. Through the digital display of the charge quantity digital display area 230, the user can directly obtain the charge quantity information of the energy feedback, which is convenient for the user to master the relationship between the driving condition of the electric vehicle and the charge quantity, and helps the user form a good habit of energy-saving riding.

[0042] Optionally, the display element is a light-emitting diode or a quantum dot light-emitting element.

[0043] The type of the light-emitting element in the display partition 221 of the charging current display area 220 is not limited and can be selected according to requirements. It can be a light-emitting diode or a quantum dot light-emitting element. Through the light-emitting element, the intensity of the corresponding charging current can be reflected, and further the magnitude of the energy feedback force can be reflected.

[0044] The instrument control system of the electric vehicle provided by the embodiment of the present invention collects the kinetic energy signal generated by the electric vehicle during driving through the energy controller according to the driving state of the electric vehicle, converts the kinetic energy signal into a feedback power signal, and determines its feedback power parameter; uses the instrument display component to receive and display the feedback power parameter output by the energy controller. By collecting and converting the kinetic energy signal into a feedback power signal through the energy controller and using the instrument display component to display the feedback power parameter, the power state of the kinetic energy generated during driving and fed back to the whole vehicle can be displayed on the instrument in real time and intuitively, which is convenient for the user to master the power information of the whole vehicle, helps the user form a habit of energy-saving riding, and improves the user experience.

[0045] Embodiment 2

[0046] Figure 3 FIG. is a schematic structural diagram of an instrument control system of an electric vehicle provided by Embodiment 2 of the present invention. The technical solution of this embodiment is applicable to the situation where the user monitors the power state of the electric vehicle in real time through the instrument display. The system can be implemented in a software and / or hardware manner and can be integrated into devices such as electric vehicles.

[0047] As Figure 3As shown in the figure, the instrument control system of the electric vehicle provided in this embodiment includes: an energy controller 100 and an instrument display component 200; the energy controller 100 is used to collect the kinetic energy signal generated during the driving of the electric vehicle according to the driving state of the electric vehicle, convert the kinetic energy signal into a feedback power signal, and determine its feedback power parameters; the instrument display component 200 is electrically connected to the energy controller 100, and is used to receive the feedback power parameters output by the energy controller 100 and display the feedback power parameters. The feedback power parameters at least include the charging current.

[0048] Optionally, it further includes: a energy storage module 400 electrically connected to the energy controller 100, and the energy storage module 400 is used to supply power to the electric vehicle; the energy controller 100 is used to charge the feedback power signal into the energy storage module 400, and is also used to determine its power consumption power parameters according to the kinetic energy signal generated by the electric vehicle during driving. The power consumption power parameters at least include the discharge current.

[0049] As Figure 3 As shown in the figure, the instrument control system of the electric vehicle provided in this embodiment includes: an energy controller 100, an instrument display component 200 and an energy storage module 400. The energy controller 100 collects in real time the kinetic energy signal generated during the driving states such as braking and coasting of the electric vehicle, converts the collected kinetic energy signal into a feedback power signal, realizes the recycling of energy, and determines the corresponding feedback power parameters according to the converted feedback power signal. The energy controller 100 sends the feedback power parameters to the instrument display component 200, and the instrument display component 200 displays in real time on its display screen the feedback power parameters sent by the received energy controller 100. The feedback power parameters at least include the charging current. The energy controller 100 also charges the feedback power signal into the energy storage module 400 for supplying power to the electric vehicle, and determines its power consumption power parameters according to the kinetic energy signal generated by the electric vehicle during starting and climbing. The power consumption power parameters at least include the discharge current. The energy controller 100 sends the power consumption power parameters to the instrument display component 200, and the instrument display component 200 displays in real time on its display screen the power consumption power parameters sent by the received energy controller 100. The power consumption power parameters at least include the discharge current. The larger the discharge current, the more power is consumed. The intuitive display of the charging power parameters and the power consumption power parameters facilitates the user to monitor the power state of the whole vehicle in real time and improves the user experience.

[0050] Among them, the content, display mode, and display position of the power consumption parameters are not limited and can be selected according to market demands. For example, the power consumption parameters may include discharge current and discharge amount; the discharge current can be reflected by setting current columns of different colors and / or different lengths to indicate the amount of power consumption. The darker the color and / or the longer the current column, the more power is consumed; the power consumption can be displayed in numerical form, which can be the power consumption of a single ride and will be automatically cleared after the electric vehicle is turned off; according to the user's selection requirements, the power consumption parameters can be displayed or turned off at any time during driving; the display position of the power consumption parameters can be adjusted according to the actual situation, and can be set adjacent to the feedback power parameters or separately displayed from the feedback power parameters. The real-time display of the power consumption parameters by the instrument display component 200 facilitates the user to understand the relationship between the driving state and power consumption of the electric vehicle. For example, during acceleration and starting or climbing, the discharge current will increase sharply, increasing the power consumption, gradually enabling the user to form a good habit of energy-saving riding.

[0051] For example Figure 3 and Figure 4 , optionally, it further includes: a memory. A discharge current database is stored in the memory 300. The discharge current database includes the first discharge current range to the Nth discharge current range. The discharge current value of the jth discharge current range is less than the discharge current value of the (j + 1)th discharge current range, where 1 ≤ j ≤ N; the instrument display component 200 includes a driving circuit 210, a charging current display area 220, and a discharge current display area 240. The discharge current display area 240 includes the first display partition to the Nth display partition arranged in sequence along the second direction. The display partition 241 includes at least one display element; the driving circuit 210 is electrically connected to the energy controller 100 and the memory 300 respectively, and is used to obtain the discharge current through the energy controller 100, and when it detects that the discharge current is in the jth discharge current range, drive the display elements of the first display partition to the jth display partition to emit light synchronously.

[0052] For example Figure 3 As shown, the instrument control system of the electric vehicle provided in this embodiment further includes a memory 300. A discharge current database is stored in the memory 300. The discharge current database includes N discharge current ranges. The discharge current value of the jth discharge current range is less than the discharge current value of the (j + 1)th discharge current range, where 1 ≤ j ≤ N. The instrument display component 200 includes a driving circuit 210, a charging current display area 220, and a discharge current display area 240. The discharge current display area 240 includes the first display partition to the Nth display partition arranged in sequence along the second direction. The display partition 241 includes at least one display element. For details, see Figure 4。The first display partition to the Nth display partition in the discharge current display area 240 correspond to the first discharge current range to the Nth discharge current range in the memory 300. The drive circuit 210 compares the discharge current in the power consumption electrical energy parameter sent by the received energy controller 100 with the discharge current range in the memory 300. When it detects that the discharge current is in the jth discharge current range, the drive circuit 210 drives each display element in the first display partition to the jth display partition in the discharge current display area 240 to emit light synchronously, so as to represent the discharge current of the corresponding intensity, and further reflect the corresponding power consumption. The larger the j of the illuminated display partition 241 in the discharge current display area 240, the larger the discharge current value and the more power consumption.

[0053] Among them, the second direction is not limited and can be set according to the actual situation. For example, the second direction can be the horizontal direction or the vertical direction. The position of the discharge current display area 240 and the shape of the display partition 241 are not limited. For example, the discharge current display area 240 can be set on the right side of the display screen, and the display partition 241 can be rectangular, elliptical, etc. The real-time and intuitive display of the discharge current facilitates the user to master the discharge state of the whole vehicle, helps the user form the habit of energy-saving riding, and improves the user experience.

[0054] Such as Figure 4 , optionally, the first display partition to the Nth display partition are divided into at least two display groups arranged in sequence, and the display elements of adjacent two display groups have different light-emitting colors, and the display elements of the same display group have the same light-emitting color.

[0055] Such as Figure 4 As shown, the first display partition to the Nth display partition in the discharge current display area 240 are divided into at least two display groups arranged in sequence. Different display groups represent different discharge current intensities. From the first display partition to the Nth display partition, the corresponding discharge current increases in turn, indicating that the power consumption increases in turn. It can be set that the display elements of adjacent two display groups have different light-emitting colors, and the display elements of the same display group have the same light-emitting color. The setting of the light-emitting colors of the display elements of each display group makes the display of the discharge current more intuitive and facilitates the user to understand the power consumption status of the whole vehicle.

[0056] Such as Figure 4 , optionally, the first display partition to the kth display partition are divided into a low-current display group, and the (k + 1)th display partition to the Nth display partition are divided into a high-current display group, 1 < k < N; the display elements of the low-current display group all have a green light-emitting color, and the display elements of the high-current display group all have a red light-emitting color.

[0057] Such as Figure 4As shown, the first display partition to the Nth display partition in the discharge current display area 240 are divided into two sequentially arranged display groups: the first display partition to the kth display partition is the low-current display group, and the (k + 1)th display partition to the Nth display partition is the high-current display group, where 1 < k < N. The low-current display group represents small-current discharge, and the high-current display group represents large-current discharge. It is possible to set the light-emitting color of the display elements in the low-current display group to be all green, and the light-emitting color of the display elements in the high-current display group to be all red. When the electric vehicle is traveling at a constant speed, the current output is stable, and the output power opening of the energy controller 100 is generally between 30% and 60%, which is small-current discharge. The light-emitting elements in the low-current display group emit green light and shine in a slightly dynamic manner. When the electric vehicle starts or climbs a slope, according to the magnitude of the current output, the light-emitting elements in the low-current display group emit green light in sequence along the second direction. When the output power opening of the energy controller 100 exceeds 60%, the light-emitting elements in the high-current display group emit red light in sequence along the second direction. When the output power opening exceeds 75% or more, all the light-emitting elements in the display partition 241 in the discharge current display area 240 emit light. By setting the low-current display group to display green and the high-current display group to display red, and setting different numbers of light-emitting display partitions 241 according to the magnitude of the current output and the output power opening of the energy controller 100, the discharge current information can be intuitively provided to the user, facilitating the user to understand the power consumption status of the entire vehicle.

[0058] In the instrument control system of the electric vehicle provided by the embodiment of the present invention, the energy controller collects and converts the kinetic energy signal into a feedback electric energy signal, and charges the feedback electric energy signal into the energy storage module to supply power to the electric vehicle. The energy controller also determines its feedback electric energy parameter and power consumption electric energy parameter according to the feedback electric energy signal and kinetic energy signal generated during the driving of the electric vehicle respectively. The instrument display component is used to display the feedback electric energy parameter and power consumption electric energy parameter, so that the power state of the kinetic energy generated during driving and fed back to the entire vehicle can be displayed intuitively in real time on the instrument, facilitating the user to master the charging and discharging information of the entire vehicle, helping the user to form the habit of energy-saving riding, and improving the user experience.
