Description

Technical Field

[0001] This application relates to the field of automatic voltage control, specifically to methods, apparatus, electronic devices, and storage media for adjusting the power supply voltage of a controller. Background Technology

[0002] With the rapid development of automotive intelligence, automotive products are showing a trend towards integration, and the controller is a product of this integration process. Functionally, a vehicle can be divided into five domains: powertrain, chassis, cockpit, autonomous driving, and body. The controller's power supply voltage is fundamental to vehicle integration, requiring long-term stability and automatic voltage recovery to ensure proper vehicle control. Current technologies typically use hardware circuits for passive voltage protection, but these measures cannot fundamentally address overvoltage and undervoltage issues; they only provide temporary output limitations.

[0003] In the prior art, reference document 1 (CN217824236U) discloses a sensor power supply protection circuit. This circuit includes: a voltage threshold setting circuit, an overvoltage protection circuit, an undervoltage protection circuit, and a current limiting circuit. The voltage threshold setting circuit sets overvoltage and undervoltage thresholds. When the supply voltage exceeds the overvoltage threshold or falls below the undervoltage threshold, the overvoltage and undervoltage protection circuits disconnect the power supply circuit. The current limiting circuit sets a current limiting threshold to limit the maximum current consumption of the sensor's downstream circuit. Reference document 1 directly disconnects the power supply circuit through the voltage threshold setting circuit, which can only temporarily limit the supply voltage of the power supply circuit and cannot achieve active protection of the supply voltage.

[0004] Therefore, given a known supply voltage, how to actively control the supply voltage within a preset range to reduce its harmful effects on subsequent circuits is a pressing technical problem that needs to be solved. Summary of the Invention

The step of comparing the supply voltage with multiple preset voltage thresholds includes: when the supply voltage is less than the first voltage threshold, the voltage threshold range is a low voltage range; when the supply voltage is greater than or equal to the first voltage threshold and less than or equal to the second voltage threshold, the voltage threshold range is a normal voltage range; when the supply voltage is greater than the second voltage threshold, the voltage threshold range is a high voltage range; wherein, the first voltage threshold is less than the second voltage threshold.

[0012] In the technical solution provided by the embodiments of this application, when the voltage threshold range is a low-voltage range, the step of adjusting the power supply voltage of the controller includes: sending a boost request to an external power supply system through the controller; during the time interval in which the boost request is not responded to by the external power supply system, if the power supply voltage is greater than a third voltage threshold, setting the output of the controller to a low-voltage mode; if the power supply voltage is less than or equal to the third voltage threshold, setting the power supply voltage of the controller to zero; after the external power supply system responds to the boost request, if the power supply voltage is greater than a fourth voltage threshold, setting the output of the controller to a low-voltage mode; wherein, the third voltage threshold is less than the fourth voltage threshold, and the low-voltage module is used to limit the voltage output capability of the controller.

[0013] In the technical solution provided in the embodiments of this application, the controller supplies power normally when the voltage threshold range is within the normal voltage range.

[0014] In the technical solution provided by the embodiments of this application, when the voltage threshold range is a high voltage range, the step of adjusting the power supply voltage of the controller includes: sending a voltage reduction request to the external power supply system through the controller; during the time interval in which the external power supply system does not respond to the voltage reduction request, if the power supply voltage is less than a fifth voltage threshold, then setting the output of the controller to a high voltage mode; if the power supply voltage is greater than or equal to the fifth voltage threshold, then setting the power supply voltage of the controller to zero; after the external power supply system responds to the voltage reduction request, if the power supply voltage is less than a sixth voltage threshold, then setting the output of the controller to a high voltage mode; wherein, the fifth voltage threshold is greater than the sixth voltage threshold, and the high voltage mode is used to limit the voltage output capability of the controller.

[0015] In the technical solution provided in the embodiments of this application, before obtaining the power supply voltage, the method further includes: filtering the initial voltage to obtain the power supply voltage.

[0016] According to one aspect of the embodiments of this application, an apparatus for adjusting the power supply voltage of a controller is provided.

It not only adjusts abnormal power supply voltages at their source but also has a hysteresis effect, ensuring the long-term stability of the controller's power supply voltage.

[0029] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0032] The inventors' research revealed that with the rapid development of automotive intelligence in recent years, vehicle products are showing a trend towards integration, and the controller is a crucial product of this integration process. Automotive controllers can be functionally divided into the powertrain domain, chassis domain, cockpit domain, autonomous driving domain, and body domain. The powertrain controller is responsible for controlling the three-electric system (battery, motor, and electronic control), including the three-in-one system, battery management system, and vehicle controller; the chassis controller includes brakes, steering, airbags, and shock absorbers; the cockpit domain includes intelligent cockpits such as instrument clusters, central control screens, and head-up displays; the body controller includes wipers, windows, and car keys; the autonomous driving domain requires capabilities such as multi-sensor fusion, localization, path planning, wireless communication, decision control, and high-speed communication. Its core is the chip's processing power, and the ultimate goal is to meet the computing power requirements of autonomous driving, simplify equipment, and improve the integration of the autonomous driving system. The controller's power supply voltage is fundamental to the integration of the vehicle. Large fluctuations in the controller's power supply voltage can cause unnecessary problems for vehicle control and may even endanger the safety of passengers and the driver during operation. Therefore, ensuring the stability of the controller's power supply voltage is crucial and closely related to vehicle control. However, in the existing technology, passive protection measures are implemented for voltage through hardware circuits. But passive protection measures cannot fundamentally solve the cause of voltage abnormality. They can only cut off the voltage output, which has a significant impact on subsequent circuits.

[0033] To address the aforementioned issues, this invention acquires the power supply voltage, compares it with a preset voltage threshold, determines the voltage threshold range within which the power supply voltage exists, and adjusts the power supply voltage within this range to achieve automatic adjustment and reduce the harm caused by abnormal power supply voltage to subsequent circuits.

[0034] like Figure 1 As shown, in one embodiment of this application, the method for adjusting the controller power supply voltage includes at least the following steps:

[0035] S110, Obtain the power supply voltage;

[0036] S120. Compare the supply voltage with multiple preset voltage thresholds to determine the voltage threshold range to which the supply voltage belongs;

[0037] S130. Adjust the power supply voltage of the controller according to the voltage threshold range.

[0038] In detail, in an exemplary embodiment of this application, the preset voltage threshold includes a first voltage threshold and a second voltage threshold. The step of comparing the supply voltage with multiple preset voltage thresholds includes: when the supply voltage is less than the first voltage threshold, the voltage threshold range is a low voltage range; when the supply voltage is greater than or equal to the first voltage threshold and less than or equal to the second voltage threshold, the voltage threshold range is a normal voltage range; when the supply voltage is greater than the second voltage threshold, the voltage threshold range is a high voltage range; wherein, the first voltage threshold is less than the second voltage threshold.

[0039] It should be noted that, as Figure 2 As shown, the preset voltage thresholds include a first voltage threshold of 12V and a second voltage threshold of 17V. The supply voltage is compared with the first voltage threshold of 12V and the second voltage threshold of 17V. When the supply voltage is less than the first voltage threshold of 12V, the voltage threshold range is the low voltage range. When the supply voltage is greater than or equal to the first voltage threshold of 12V and less than or equal to the second voltage threshold of 17V, the voltage threshold range is the normal voltage range. When the supply voltage is greater than the second voltage threshold of 17V, the voltage threshold range is the high voltage range.

[0040] More specifically, in an exemplary embodiment of this application, the step of adjusting the power supply voltage of the controller when the voltage threshold range is a low-voltage range includes: sending a boost request to an external power supply system through the controller; during the time interval in which the boost request is not responded to by the external power supply system, if the power supply voltage is greater than a third voltage threshold, setting the output of the controller to a low-voltage mode; if the power supply voltage is less than or equal to the third voltage threshold, setting the power supply voltage of the controller to zero; after the external power supply system responds to the boost request, if the power supply voltage is greater than a fourth voltage threshold, setting the output of the controller to a low-voltage mode; wherein the third voltage threshold is less than the fourth voltage threshold, and the low-voltage module is used to limit the voltage output capability of the controller.

[0041] Specifically, when the voltage threshold range is in the low-voltage range, the power supply voltage of the controller is adjusted, such as... Figure 2 As shown, the third voltage threshold is 8V, and the fourth voltage threshold is 9V. Figure 3 As shown, during the 0-1 second (S) period, the supply voltage is within the normal voltage range, and the controller's voltage output capability is 100%. When the supply voltage is lower than the first voltage threshold of 12V, the controller sends a boost request to the external power supply system. During the 1-5 second (S) period, the external power supply system does not respond to the boost request, and the supply voltage shows a decreasing trend. During the 1-3 second (S) period, the supply voltage drops from the first voltage threshold of 12V to the third voltage threshold of 8V, and the controller's output is set to low-voltage mode, such as... Figure 3 As shown, the low-voltage mode is used to limit the controller's voltage output capability. When the supply voltage drops from the first voltage threshold of 12V to the third voltage threshold of 8V, the controller's voltage output capability changes with the supply voltage: from 100% to 0%. When the supply voltage is less than or equal to the third threshold voltage of 8V, the controller's voltage output capability is 0%. During 3-5 seconds (S), the supply voltage continues to drop to 6V. At the 5th second (S), the external power supply system responds to the boost request and charges the controller, causing the supply voltage to begin to rise. During 5-7 seconds (S), the supply voltage rises from 5V to the fourth voltage threshold of 9V. When the supply voltage exceeds the fourth voltage threshold of 9V, the controller's voltage output capability begins to gradually recover. During 7-9 seconds (S), the supply voltage rises from the fourth voltage threshold of 9V to the first voltage threshold of 12V, setting the controller's output to low-voltage mode. Figure 3 As shown, the low-voltage mode is used to limit the voltage output capability of the controller. When the supply voltage rises from the fourth voltage threshold of 9V to the first voltage threshold of 12V, the voltage output capability of the controller changes with the supply voltage: gradually recovering from 0% to 100%.

[0042] More specifically, in an exemplary embodiment of this application, the controller supplies power normally when the voltage threshold range is within the normal voltage range. For example... Figure 2 As shown, when the supply voltage is greater than or equal to the first voltage threshold of 12V and less than or equal to the second voltage threshold of 17V, the controller's voltage output capability is 100%. If the supply voltage is 16V, the controller outputs a supply voltage of 16V.

[0043] More specifically, in an exemplary embodiment of this application, the step of adjusting the power supply voltage of the controller when the voltage threshold range is a high-voltage range includes: sending a step-down request to an external power supply system through the controller; during the time interval in which the step-down request is not responded to by the external power supply system, if the power supply voltage is less than a fifth voltage threshold, setting the output of the controller to a high-voltage mode; if the power supply voltage is greater than or equal to the fifth voltage threshold, setting the power supply voltage of the controller to zero; after the external power supply system responds to the step-down request, if the power supply voltage is less than a sixth voltage threshold, setting the output of the controller to a high-voltage mode; wherein the fifth voltage threshold is greater than the sixth voltage threshold, and the high-voltage mode is used to limit the voltage output capability of the controller.

[0044] It should be noted that when the voltage threshold range is within the high-voltage range, the power supply voltage of the controller needs to be adjusted, such as... Figure 2 As shown, the fifth voltage threshold is 19V, and the sixth voltage threshold is 18V. Figure 4 As shown, during the 0-1 second (S) period, the supply voltage is within the normal voltage range, and the controller's voltage output capability is 100%. When the supply voltage exceeds the second voltage threshold of 17V, the controller sends a voltage reduction request to the external power supply system. During the 1-5 second (S) period, the external power supply system does not respond to the voltage reduction request, and the supply voltage shows an upward trend. During the 1-3 second (S) period, the supply voltage rises from the second voltage threshold of 17V to the fifth voltage threshold of 19V, setting the controller's output to high-voltage mode, as shown below. Figure 4 As shown, the high-voltage mode is used to limit the controller's voltage output capability. When the supply voltage rises from the second voltage threshold of 17V to the fifth voltage threshold of 19V, the controller's voltage output capability changes with the supply voltage: from 100% to 0%; when the supply voltage is greater than or equal to the fifth threshold voltage of 19V, the controller's voltage output capability is 0%; during 3-5 seconds (S), the supply voltage continues to rise to 21V; at the 5th second (S), the external power supply system responds to the voltage reduction request and discharges the controller, and the supply voltage begins to decrease. During 5-7 seconds (S), the supply voltage drops from 21V to the sixth voltage threshold of 18V. When the supply voltage is less than the sixth voltage threshold of 18V, the controller's voltage output capability begins to gradually recover. During 7-9 seconds (S), the supply voltage gradually decreases from the sixth voltage threshold of 18V to the second voltage threshold of 17V, setting the controller's output to high-voltage mode, as shown... Figure 4As shown, the high-voltage mode is used to limit the voltage output capability of the controller. When the supply voltage drops from the sixth voltage threshold of 18V to the second voltage threshold of 17V, the voltage output capability of the controller changes with the supply voltage: gradually recovering from 0% to 100%.

[0045] In a specific embodiment of this application, before obtaining the supply voltage, the method further includes filtering the initial voltage to obtain the supply voltage. Filtering the initial voltage to eliminate interference from other signals improves the accuracy of the obtained supply voltage.

[0046] This invention provides a technical solution for adjusting the power supply voltage of a controller. It obtains the filtered power supply voltage, compares it with a preset voltage threshold to determine the voltage threshold range to which the power supply voltage belongs, and adjusts the controller's voltage threshold range accordingly. If the power supply voltage is in the low-voltage range, it is boosted and the output ratio is limited; if the power supply voltage is in the normal range, it is output normally; if the power supply voltage is in the high-voltage range, it is de-energized and the output ratio is limited. This invention limits the power supply voltage based on its voltage threshold range, achieving automatic adjustment of the power supply voltage, addressing the root cause of voltage anomalies, and ensuring gradual voltage recovery, reducing damage to subsequent circuits and maintaining a long-term stable power supply voltage for the controller.

[0053] In detail, in another exemplary embodiment, the adjustment module 530 includes:

[0054] The low-voltage range adjustment unit is used to send a boost request to the external power supply system through the controller when the voltage threshold range is low-voltage. During the time interval when the boost request is not responded to by the external power supply system, if the supply voltage is greater than the third voltage threshold, the controller output is set to low-voltage mode; if the supply voltage is less than or equal to the third voltage threshold, the controller supply voltage is set to zero. After the external power supply system responds to the boost request, if the supply voltage is greater than the fourth voltage threshold, the controller output is set to low-voltage mode. The third voltage threshold is less than the fourth voltage threshold, and the low-voltage module is used to limit the voltage output capability of the controller.

[0055] In detail, in another exemplary embodiment, the adjustment module 530 further includes:

[0056] The normal voltage output unit is used to ensure that the controller is powered normally when the voltage threshold range is within the normal voltage range.

[0057] In detail, in another exemplary embodiment, the adjustment module 530 further includes:

[0058] The high-voltage range adjustment unit is used to send a voltage reduction request to the external power supply system through the controller when the voltage threshold range is in the high-voltage range. During the time interval when the voltage reduction request is not responded to by the external power supply system, if the supply voltage is less than the fifth voltage threshold, the controller output is set to high-voltage mode; if the supply voltage is greater than or equal to the fifth voltage threshold, the controller supply voltage is set to zero. After the external power supply system responds to the voltage reduction request, if the supply voltage is less than the sixth voltage threshold, the controller output is set to high-voltage mode. The fifth voltage threshold is greater than the sixth voltage threshold, and the high-voltage mode is used to limit the voltage output capability of the controller.
