DETAILED DESCRIPTION

[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

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

[0057] Figure 1 A schematic diagram of an application scenario provided for this application, such as Figure 1 As shown, the specific application scenario of the present application is: the voltage information display of the battery in the vehicle is extremely important for driving the vehicle, especially when the vehicle is ignited and started. The vehicle user such as the driver needs to judge whether the vehicle engine can start normally based on the battery voltage information displayed in the vehicle.

[0058] In combination with the above scenario, it can be seen that by adding a voltage display device to the battery terminal in the vehicle, there is a technical problem that the user is not convenient to obtain information, thereby reducing the user experience.

[0059] The battery voltage information display method provided in the present application integrates a flywheel motor device into the vehicle-mounted instrument system. After the vehicle is started, the instrument equipment in the vehicle-mounted instrument system controls the flywheel acceleration and deceleration discharge process through the flywheel motor device, detects and displays the battery voltage, and solves the technical problem of poor convenience in users obtaining information, thereby reducing user experience.

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

[0061] Figure 2 A flowchart of a method for displaying battery voltage information provided by an embodiment of the present application is shown in FIG. Figure 2 As shown, the method includes:

[0062] 201. In response to a start signal of a vehicle, control a battery in the vehicle to supply power to a flywheel motor device, so that the flywheel motor device controls a target flywheel to rotate faster.

[0063] Exemplarily, the execution subject of this embodiment may be an instrument device in a vehicle instrument system. An existing flywheel motor device in a vehicle is integrated into the vehicle instrument system, and the flywheel motor device is used to control the 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 solution provided in an embodiment of the present application, such as Figure 3 As shown, when the vehicle is started, the vehicle generates a start signal such as an accessory power (ACC) signal, and transmits the start signal to the instrument device. In response to the start signal, the instrument device can send a control signal to the battery in the vehicle to control the battery to supply power to the flywheel motor device (referred to as the flywheel motor), so that the flywheel motor device can control the corresponding target flywheel that is not connected to the counterweight block to accelerate the rotation.

[0064] 202. 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, control the storage battery to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration discharge state.

[0065] For example, in combination Figure 3 During the acceleration of the target flywheel, the instrument device monitors the speed of the target flywheel in real time and compares it with the preset speed. If the instrument device determines that the current speed of the target flywheel is greater than or equal to the preset speed, a stop signal can be sent to the battery in the vehicle to control the battery to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration discharge state, so as to control the target flywheel to decelerate.

[0066] For example, when the flywheel accelerates to a constant speed a, the power supply to the flywheel is stopped to accelerate. The flywheel device switches to a deceleration power generation state, and the discharge is reversely connected back to the original circuit to control the target flywheel to decelerate and rotate, while reversely charging the battery.

[0067] It is worth adding that the constant speed a is set by the flywheel calibration. Generally, at this speed, the flywheel motor device enters the power generation mode, and the initial discharge voltage of the corresponding flywheel motor device should be 1.1~1.2 times the rated voltage of the battery. Among them, for the upper and lower limits of the multiples given here, the lower limit value needs to consider that the initial discharge voltage of the flywheel motor device is higher than the rated voltage of the battery, and the upper limit value should not be too large to avoid causing damage to the electrical appliances. It can be adjusted according to the configuration of the electrical appliances of the whole vehicle, but the lower limit value is not allowed to be lower than the rated voltage, and the upper limit value is not allowed to exceed the maximum withstand voltage of the electrical system of the whole vehicle.

[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, in combination Figure 3 When the flywheel motor device is in the deceleration discharge state, the target flywheel continues to decelerate. As the flywheel decelerates, if the initial discharge voltage of the flywheel device is greater than the battery voltage, as the discharge voltage of the flywheel motor device decreases, the discharge circuit current of the flywheel motor device gradually decreases from a certain value to zero, and then gradually increases in the opposite direction. The instrument equipment collects the discharge current value of the flywheel motor device in real time through the 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 the voltage sensor for processing.

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

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

[0072] In this embodiment, a method for displaying battery voltage information is provided, in which an existing flywheel motor device in a vehicle is integrated into an on-board instrument system. After the vehicle is started, the instrument equipment in the on-board instrument system controls the flywheel acceleration and deceleration discharge process through the flywheel motor device, detects and displays the battery voltage, and does not require additional hardware to reduce costs. It is also convenient for users to directly obtain battery voltage information, thereby improving user experience.

[0073] Figure 4 A flow chart of another method for displaying battery voltage information provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the method includes:

[0074] 301. In response to a start signal of a vehicle, control a storage battery in the vehicle to supply power to a flywheel motor device, so that the flywheel motor device controls a target flywheel to rotate faster.

[0075] Exemplarily, this step may refer to step 201 and will not be described in detail here.

[0076] 302. 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, control the storage battery to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration discharge state.

[0077] Exemplarily, this step may refer to step 202 and will not be described in detail 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 rotation speed of the target flywheel; and determine the discharge voltage value of the flywheel motor device according to the current rotation speed of the target flywheel.

[0079] Exemplarily, during the process of the flywheel motor device being in the deceleration discharge state, the target flywheel continues to decelerate. As the flywheel decelerates, the instrument device collects the discharge current value of the flywheel motor device in real time through the current sensor, and detects the collected discharge current value. If the instrument device determines that the collected discharge current value drops to zero for the first time, the current speed of the target flywheel can be monitored through the speed sensor, and according to the current speed of the target flywheel, the electromotive force generated by the flywheel motor device at the current speed can be calculated through a preset formula; or, the flywheel motor device is in a discharge state, which is equivalent to a generator. According to the current speed of the target flywheel, the speed of the flywheel motor device cutting the magnetic flux lines is determined, and the speed of cutting the magnetic flux lines will correspond to a voltage value; and then 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 speed, which is used to represent the battery discharge voltage, which can avoid the influence of loop resistance and the like, and improve the accuracy of the instrument in measuring the battery voltage.

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

[0081] Exemplarily, this step may refer to step 203 and will not be described in detail 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 is displayed, and a prompt message is displayed; wherein the prompt message is used to prompt the user that the current battery voltage is insufficient.

[0083] For example, Figure 5 A logic block diagram of an emergency start function solution provided in an embodiment of the present application, such as Figure 5As shown, after the battery voltage detection of the vehicle is completed, the instrument device judges the voltage information of the detected battery. 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, for example, it is less than a preset threshold, the voltage information is directly displayed through the instrument device. At the same time, a prompt message is generated and displayed by the instrument device to prompt 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 satisfies the voltage value required for starting the engine in the vehicle, displaying the voltage information.

[0085] For example, in combination Figure 5 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 meets the voltage value required for starting the engine in the vehicle, for example, greater than or equal to a preset threshold, the voltage information is displayed through the instrument device.

[0086] For example, after the vehicle voltage detection is completed, based on the voltage detection module of the instrument equipment, if it is determined that the battery voltage is sufficient to start the engine, the battery voltage will be displayed on the instrument equipment and the emergency start action will not be performed; if it is determined that the battery voltage is insufficient to start the engine, the battery voltage value will be displayed on the instrument equipment and an indication of insufficient voltage will be given.

[0087] 306. Display a soft switch; wherein the soft switch is used to indicate whether the user currently selects the emergency start state.

[0088] For example, in combination Figure 5 When the vehicle's battery voltage detection is completed and the battery voltage information is displayed, based on the instrument equipment, the vehicle instrument system can be set and the instrument display soft switch can be used to indicate whether the user currently selects the emergency start state, that is, it is up to the driver to decide whether to start the emergency start.

[0089] 307. In response to a touch operation performed by a user on a soft switch within a preset interval, control the target flywheel to be connected to the counterweight; wherein the touch operation is used to indicate a currently selected emergency start state.

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

[0091] For example, combining Figure 5After collecting the voltage information, whether to select emergency start within the interval time T, if the user selects emergency start through the soft switch within the interval time T, the target flywheel is connected to the counterweight block; if the user does not select emergency start through the soft switch within the interval time T, the battery is controlled to supply power to the flywheel motor device, and stop supplying power, etc., to re-detect the voltage information of the battery.

[0092] 308. Control the storage battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate rotation, so as to perform the vehicle ignition starting operation.

[0093] For example, after the target flywheel is connected to the counterweight, the instrument device can send a control signal to the battery based on the battery power feeding start module of the instrument device to control the battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate, and the target flywheel accelerates to store energy for the vehicle to perform the vehicle ignition start operation and complete the emergency start operation. Furthermore, the voltage detection module in the instrument device is combined with the battery power feeding start module to reduce the complexity of the device, so that the battery in the vehicle can support the vehicle ignition start through the flywheel energy storage discharge in the power feeding state.

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

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

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

[0097] For example, in combination Figure 5After the target flywheel is connected to the counterweight, the instrument device can send a control signal to the battery to control the battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate, and the target flywheel accelerates to store energy. At the same time, the instrument device detects the current speed of the target flywheel in real time to obtain the countdown for the current speed of the target flywheel to reach the preset critical speed, that is, the countdown information, and displays the countdown information through the instrument display function of the instrument device. If the instrument device monitors that the current speed of the target flywheel reaches the preset critical speed, it sends a stop signal to the battery to control the battery to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration discharge state, the target flywheel stops accelerating, the flywheel motor device switches to the power generation mode, and the discharge is reversed and connected back to the original circuit to supply power to the battery, so as to support the driver to perform the vehicle ignition start operation.

[0098] In particular, the critical speed required for acceleration in the flywheel counterweight state should be that after switching to the discharge state, the initial discharge voltage is the rated voltage of the battery.

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

[0100] Specifically, combined Figure 5 After the driver starts the vehicle, the instrument equipment monitors the ignition status of the vehicle. If it is determined that the vehicle has not been successfully ignited, the battery is controlled to supply power to the flywheel motor device, so that the flywheel motor device controls the flywheel to accelerate energy storage, and then enters the battery voltage information detection and display stage.

[0101] In this embodiment, on the basis of the above embodiment, a flywheel motor device is integrated in the instrument. After the vehicle is started (ACC power), the instrument equipment controls the discharge process of the flywheel after acceleration through the flywheel motor device, and detects the discharge voltage of the flywheel motor device as the battery voltage, so that the battery voltage measurement is more accurate; on the other hand, in the power feeding state, the flywheel energy storage discharge supports the vehicle ignition start, which conveniently solves the power feeding start problem.

[0103] The first control module 401 is used to control the battery in the vehicle to supply power to the flywheel motor device in response to a start signal of the vehicle, so that the flywheel motor device controls the target flywheel to rotate faster;

[0104] The second control module 402 is used to monitor the current speed of the target flywheel; if it is determined that the current speed is greater than or equal to the preset speed, the storage battery is controlled to stop supplying power to the flywheel motor device, so that the flywheel motor device is in a deceleration 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] The display module 404 is used to determine the discharge voltage value as the voltage information of the battery and display the voltage information of the battery.

[0107] In a possible implementation, the display module 404 is specifically used to: 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, then display the voltage information and display a prompt message; wherein the prompt message is used to prompt the user that the current battery voltage is insufficient.

[0108] In a possible implementation, the display module 404 is specifically used, after being used to display the prompt information, to: display a soft switch; wherein the soft switch is used to indicate whether the user currently selects the emergency start state; in response to the user's touch operation on the soft switch within a preset interval, control the target flywheel to be connected to the counterweight block; wherein the touch operation is used to indicate that the emergency start state is currently selected; control the battery to supply power to the flywheel motor device, so that the flywheel motor device controls the target flywheel to accelerate rotation to perform the vehicle ignition start operation.
