These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0056] It should be noted that this application can be used in the field of vehicle technology, or in any field other than vehicle technology. The application field of this application is not limited.

[0057] Figure 1 This application provides an illustration of an application scenario, such as... Figure 1 As shown, the specific application scenario of this application is as follows: The display of battery voltage information in a vehicle is extremely important for driving, especially when the vehicle is started. Vehicle users, such as drivers, need to judge whether the vehicle engine can start normally based on the battery voltage information displayed in the vehicle.

[0058] Based on the above scenarios, it is clear that adding a voltage display device to the battery in a vehicle presents a technical problem: poor user access to information, which in turn reduces the user experience.

[0059] The battery voltage information display method provided in this application integrates a flywheel motor device into the vehicle instrument system. After the vehicle starts, the instrument equipment in the vehicle instrument system controls the flywheel to accelerate and decelerate the discharge process through the flywheel motor device, detects and displays the battery voltage, and solves the technical problem of poor user access to information, which reduces the user experience.

[0060] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0061] Figure 2 This is a flowchart illustrating a method for displaying battery voltage information according to an embodiment of this application. Figure 2 As shown, the method includes:

[0062] 201. In response to the vehicle's start signal, control the vehicle's battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate its rotation.

[0063] For example, the execution subject of this embodiment can be an instrument device in an in-vehicle instrument system. An existing flywheel motor device in the vehicle is integrated into the in-vehicle instrument system. This flywheel motor device is used to control the rotational speed of a target flywheel in the vehicle, such as a flywheel without a counterweight. Figure 3 A logic block diagram of a voltage detection scheme provided in an embodiment of this application is shown below. Figure 3 As shown, when the vehicle starts, it generates a start signal such as Accessory Power (ACC) signal and transmits it to the instrument panel. In response to the start signal, the instrument panel can send a control signal to the battery in the vehicle to control the battery to supply power to the flywheel motor (or flywheel motor for short), so that the flywheel motor can control the target flywheel that is not connected to the counterweight to accelerate its rotation.

[0064] 202. Monitor the current rotational speed of the target flywheel; if the current rotational speed is determined to be greater than or equal to the preset rotational speed, control the battery to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration and discharge state.

[0065] For example, combined Figure 3 During the acceleration of the target flywheel, the instrumentation monitors its rotational speed in real time and compares it with a preset speed. If the instrumentation determines that the current rotational speed of the target flywheel is greater than or equal to the preset speed, it can send a stop signal to the vehicle's battery to control the battery to stop supplying power to the flywheel motor, thus putting the flywheel motor into a deceleration and discharge state to control the target flywheel to decelerate.

[0066] For example, when the flywheel accelerates to a fixed speed 'a', the power supply to the flywheel for acceleration is stopped. The flywheel device switches to a deceleration and power generation state, discharging in reverse and connecting back to the original circuit to control the target flywheel to decelerate and rotate, while simultaneously reversing the charge to the battery.

[0067] It's worth noting that this set speed 'a' is determined by the flywheel calibration. Generally, at this speed, when the flywheel motor enters generator mode, the initial discharge voltage of the flywheel motor should be 1.1 to 1.2 times the rated voltage of the battery. Regarding the upper and lower limits of this multiple, the lower limit should consider that the initial discharge voltage of the flywheel motor is higher than the rated voltage of the battery, while the upper limit should not exceed this range excessively to avoid damage to electrical components. Adjustments can be made based on the vehicle's electrical system configuration, but the lower limit must not be lower than the rated voltage, and the upper limit must not exceed the maximum withstand voltage of the vehicle's electrical system.

[0068] 203. Monitor the discharge current value of the flywheel motor device; if it is determined that the discharge current value drops to zero for the first time, collect the discharge voltage value of the flywheel motor device.

[0069] For example, combined Figure 3 During the deceleration and discharge process of the flywheel motor device, the target flywheel continuously decelerates. As the flywheel decelerates, if the initial discharge voltage of the flywheel device is greater than the battery voltage, the discharge circuit current of the flywheel motor device will gradually decrease from a certain value to zero, and then gradually increase in the opposite direction as the discharge voltage of the flywheel motor device decreases. The instrumentation equipment collects the discharge current value of the flywheel motor device in real time through a current sensor and detects the collected discharge current value. If it is determined that the collected discharge current value drops to zero for the first time, the discharge voltage value of the flywheel motor device at the current moment can be collected through a voltage sensor for further processing.

[0070] 204. Determine the discharge voltage value as the battery voltage information and display the battery voltage information.

[0071] For example, combined Figure 3 The instrumentation equipment determines the collected discharge voltage value as the battery voltage information, that is, obtains the battery voltage, and displays the battery voltage through the instrument in the vehicle instrument system.

[0072] This embodiment provides a method for displaying battery voltage information. The existing flywheel motor device in the vehicle is integrated into the vehicle instrument system. After the vehicle is started, the instrument device in the vehicle instrument system controls the flywheel acceleration and deceleration discharge process through the flywheel motor device to detect and display the battery voltage. No new hardware is required to reduce costs, and it is convenient for users to directly obtain the battery voltage information, thereby improving the user experience.

[0073] Figure 4 A flowchart illustrating another method for displaying battery voltage information provided in this application embodiment is shown below. Figure 4 As shown, the method includes:

[0074] 301. In response to the vehicle's start signal, control the vehicle's battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate its rotation.

[0075] For example, this step can be referred to as step 201, which will not be repeated here.

[0076] 302. Monitor the current rotational speed of the target flywheel; if the current rotational speed is determined to be greater than or equal to the preset rotational speed, control the battery to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration and discharge state.

[0077] For example, this step can be referred to as step 202, which will not be repeated here.

[0078] 303. Monitor the discharge current value of the flywheel motor device; if it is determined that the discharge current value drops to zero for the first time, collect the current speed of the target flywheel; and determine the discharge voltage value of the flywheel motor device based on the current speed of the target flywheel.

[0079] For example, during the deceleration and discharge process of the flywheel motor device, the target flywheel continuously decelerates. As the flywheel decelerates, the instrument uses a current sensor to collect the discharge current value of the flywheel motor device in real time and detects the collected discharge current value. If the instrument determines that the collected discharge current value drops to zero for the first time, it can monitor the current rotational speed of the target flywheel using a speed sensor. Based on the current rotational speed of the target flywheel, the electromotive force generated by the flywheel motor device at the current rotational speed can be calculated using a preset formula. Alternatively, if the flywheel motor device is in a discharge state, it acts like a generator. Based on the current rotational speed of the target flywheel, the speed at which the flywheel motor device cuts magnetic field lines is determined, and this cutting speed corresponds to a voltage value. Thus, the discharge voltage value of the flywheel motor device is obtained. Furthermore, when the current value becomes zero, the corresponding flywheel discharge voltage is obtained through the flywheel rotational speed and used to represent the battery discharge voltage. This avoids the influence of loop resistance and other factors, improving the accuracy of the instrument in measuring the battery voltage.

[0080] 304. Determine the discharge voltage value as the battery voltage information.

[0081] For example, this step can be referred to as step 203, which will not be repeated here.

[0082] 305. If it is determined that the voltage value corresponding to the voltage information does not meet the voltage value required for starting the engine in the vehicle, the voltage information and a prompt message will be displayed; the prompt message is used to inform the user that the current battery voltage is insufficient.

[0083] For example, Figure 5 A logic block diagram of an emergency startup function scheme provided in an embodiment of this application is shown below. Figure 5As shown, after the vehicle's battery voltage detection is completed, the instrument device judges the detected battery voltage information. If it is determined that the voltage value corresponding to the voltage information does not meet the voltage value required for starting the vehicle's engine, such as being less than a certain preset threshold, the instrument device will directly display the voltage information. At the same time, the instrument device will generate and display a prompt message to remind the user that the current battery voltage is insufficient.

[0084] In one example, after step 304, the method further includes: if it is determined that the voltage value corresponding to the voltage information meets the voltage value required for starting the engine in the vehicle, then display the voltage information.

[0085] For example, combined Figure 5 After the vehicle's battery voltage is detected, the instrument panel judges the detected battery voltage information. If it is determined that the voltage value corresponding to the voltage information meets the voltage value required for starting the vehicle's engine, such as being greater than or equal to a certain preset threshold, the voltage information is displayed on the instrument panel.

[0086] For example, once the vehicle voltage detection is complete, if the voltage detection module of the instrument panel determines that the battery voltage is sufficient to start the engine, the battery voltage will be displayed on the instrument panel, and no emergency start action will be performed; if the battery voltage is determined to be insufficient to start the engine, the battery voltage value will be displayed on the instrument panel, and a message indicating insufficient voltage will be displayed.

[0087] 306. Display soft switch; wherein, the soft switch is used to indicate whether the user has selected the emergency start state.

[0088] For example, combined Figure 5 Once the vehicle's battery voltage detection is complete and the battery voltage information is displayed, a soft switch can be set and displayed on the instrument panel via the in-vehicle instrument system. This soft switch indicates whether the user has selected the emergency start mode, meaning the driver decides whether to activate the emergency start.

[0089] 307. In response to a user's touch operation on the soft switch within a preset interval, the target flywheel is connected to the counterweight; wherein the touch operation is used to indicate the current selection of the emergency start state.

[0090] For example, when a user touches the soft switch within a preset interval to indicate that the current emergency start state is selected, the instrument can respond to the touch operation by sending a control signal to a drive device, causing the drive device to control the target flywheel to connect with the counterweight, thereby increasing the inertia of the target flywheel itself.

[0091] For example, combining Figure 5After collecting voltage information, the system checks whether emergency start is selected within an interval T. If the user selects emergency start within the interval T via a soft switch, the target flywheel is connected to the counterweight. If the user does not select emergency start within the interval T via a soft switch, the system performs operations such as controlling the battery to supply power to the flywheel motor and stopping power supply, in order to re-detect the battery voltage information.

[0092] 308. Control the battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate rotation in order to perform the vehicle ignition and start operation.

[0093] For example, after the target flywheel is connected to the counterweight, the instrument's battery-powered start-up module can send a control signal to the battery to control the battery to supply power to the flywheel motor. This causes the flywheel motor to control the target flywheel to accelerate and rotate, storing energy for the vehicle to perform ignition and start-up operations, thus completing an emergency start-up. Furthermore, by combining the voltage detection module in the instrument with the battery-powered start-up module, the complexity of the device is reduced, allowing the vehicle's battery to support vehicle ignition and start-up through flywheel energy storage and discharge even when the battery is depleted.

[0094] In one example, step 308 includes the following steps:

[0095] The first step is to control the battery to supply power to the flywheel motor and display the countdown information of the target flywheel; the countdown information represents the countdown before the current speed of the target flywheel reaches the preset critical speed.

[0096] The second step is to control the battery to stop supplying power to the flywheel motor if the current speed of the target flywheel is detected to reach the preset critical speed, so that the flywheel motor is in a deceleration and discharge state to perform the vehicle ignition and start-up operation.

[0097] For example, combined Figure 5After the target flywheel is connected to the counterweight, the instrument can send a control signal to the battery to control the battery to supply power to the flywheel motor. This causes the flywheel motor to control the target flywheel to accelerate and store energy. Simultaneously, the instrument monitors the current speed of the target flywheel in real time to obtain a countdown timer for when the current speed reaches a preset critical speed. This countdown information is displayed on the instrument's display. If the instrument detects that the target flywheel's current speed has reached the preset critical speed, it sends a stop signal to the battery to stop supplying power to the flywheel motor. This puts the flywheel motor in a deceleration and discharge state, the target flywheel stops accelerating, and the flywheel motor switches to generator mode, reversing the discharge to supply power to the battery, thus enabling the driver to start the vehicle.

[0098] Specifically, the critical speed required for acceleration under flywheel counterweight conditions should be the initial discharge voltage of the battery rated voltage after switching to discharge mode.

[0099] In one example, after step 308, the method further includes: if the ignition status of the vehicle indicates that the vehicle has not been successfully ignited, then controlling the battery to supply power to the flywheel motor.

[0100] Specifically, in combination Figure 5 After the driver starts the vehicle, the instrument panel monitors the vehicle's ignition status. If it is determined that the vehicle has not started successfully, it controls the battery to supply power to the flywheel motor, which then controls the flywheel to accelerate energy storage. The system then enters the stage of detecting and displaying the battery's voltage information.

[0101] In this embodiment, based on the above embodiments, a flywheel motor device is integrated into the instrument panel. After the vehicle starts (ACC power), the instrument panel controls the flywheel to accelerate and then decelerate to discharge through the flywheel motor device. The discharge voltage of the flywheel motor device is detected as the battery voltage, making the battery voltage measurement more accurate. On the other hand, in the power-off state, the flywheel stores energy and discharges to support the vehicle ignition and start-up, conveniently solving the problem of starting when the power is off.

[0102] Figure 6 This is a schematic diagram of the structure of a battery voltage information display device provided in an embodiment of this application, as shown below. Figure 6 As shown, this device is applied to the instrument equipment in an in-vehicle instrument system, which also includes a flywheel motor device; the device includes:

[0103] The first control module 401 is used to respond to the vehicle's start signal and control the vehicle's battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate its rotation.

[0104] The second control module 402 is used to monitor the current rotation speed of the target flywheel; if it is determined that the current rotation speed is greater than or equal to the preset rotation speed, it controls the battery to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration and discharge state.

[0105] The acquisition module 403 is used to monitor the discharge current value of the flywheel motor device; if it is determined that the discharge current value drops to zero for the first time, the discharge voltage value of the flywheel motor device is acquired.

[0106] Display module 404 is used to determine the discharge voltage value as the battery voltage information and to display the battery voltage information.
