Description

Technical Field

[0001] This application relates to the field of new energy vehicle technology, specifically to a vehicle safety control method, device, electronic equipment, and storage medium. Background Technology

[0002] With the increasing popularity of new energy vehicles, more and more people are choosing to drive them for transportation. The controllers and various electronic components of new energy vehicles work together to enhance the technological experience for drivers. However, new energy vehicles are highly dependent on electronic technology, and the information transmission between these components affects vehicle safety, which has always been a top concern for both users and manufacturers. Currently, vehicle safety is primarily monitored and detected through the controller. When an anomaly is detected, the controller takes action, but this approach cannot comprehensively monitor vehicle safety and take corresponding measures, thus failing to reduce the risk factor.

[0003] Therefore, how to comprehensively control vehicle safety and take corresponding measures is a technical problem that urgently needs to be solved.

[0004] Prior art document 1 (CN114675568A) provides a functional safety control system for an electric vehicle and an electric vehicle, relating to the field of automotive technology. This functional safety control system for an electric vehicle includes: a domain controller integrated from at least two controllers, wherein the domain controller includes: a functional safety module; an input module and an execution module connected to the functional safety module; wherein the functional safety module verifies the signals input by the input module and, if the verification is successful, sends control commands to the execution module. Prior art document 1's technical solution is simplistic, only verifying the signals from the input module and sending control commands only upon successful verification, thus failing to achieve comprehensive vehicle monitoring.

[0005] Prior art document 2 (CN105416206B) relates to an electric vehicle controller. The controller is electrically connected to a battery and a high-voltage relay in the battery pack. The controller includes a main processor, a slave processor, and a drive output module connected to the coil of the high-voltage relay. The main processor and the slave processor are connected via an SPI bus, and the slave processor monitors the main processor. The main processor is connected to the drive output module to control the high-voltage relay through the drive output module. The slave processor is connected to the battery to monitor the battery voltage. The slave processor is also connected to the drive output module to disable the drive output module. Prior art document 2 only monitors the high-voltage relay and battery voltage in the vehicle, and cannot provide comprehensive control. It cannot proactively monitor for other problems that may occur while the vehicle is in motion. Summary of the Invention

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.

[0035] The inventors' research revealed that while new energy vehicles have become a common mode of transportation, users prioritize safety when choosing them. Therefore, safety is a constantly evolving and evolving issue, with a focus on achieving near-perfect safety. Current technologies primarily rely on controllers to monitor and detect vehicle safety, thus enabling safety control. However, when anomalies occur, the inability to fully control and monitor the vehicle, and the inability to take appropriate measures, creates safety hazards while driving.

[0036] To address the aforementioned problems, this invention provides a vehicle safety control method, device, electronic device, and storage medium; by monitoring multiple circuits in the vehicle, comprehensive monitoring of the vehicle is achieved; when one of the circuits in the vehicle malfunctions, a reset signal is output; a detection signal is generated based on the reset signal; and a reset operation of the vehicle's control chip is performed based on the reset signal and the detection signal.

[0037] Figure 1 This is a flowchart illustrating a vehicle safety control method as shown in an exemplary embodiment of this application.

[0038] like Figure 1 As shown, in an exemplary embodiment of this application, the vehicle safety control method includes at least the following steps:

[0039] S110 provides a drive circuit, analog signal circuit, battery circuit, control chip and braking circuit. The control chip collects the control signals output by the drive circuit, analog signal circuit and battery circuit and determines the level of the control signal.

[0040] S120, the control chip generates a reset signal based on the control signal;

[0041] S130, The braking circuit generates a detection signal based on the reset signal. When the reset signal is low, the detection signal is switched from low to high.

[0042] S140. If the duration of the low-level reset signal and the high-level detection signal is greater than or equal to the preset time threshold, the braking circuit sends a reset command to the control chip.

[0043] In detail, in an exemplary embodiment of this application, the driving circuit includes a high-side diagnostic unit and a low-side diagnostic unit. In step S110, the control signal of the driving circuit is acquired by the control chip, and the level of the control signal is determined, including: acquiring a first diagnostic signal output by the high-side diagnostic unit and a second diagnostic signal output by the low-side diagnostic unit; determining the level of the control signal based on the first diagnostic signal and the second diagnostic signal; when the high-side diagnostic unit and the low-side diagnostic unit are abnormal, the first diagnostic signal is high and the second diagnostic signal is low, and the control signal is low; when the high-side diagnostic unit and the low-side diagnostic unit are normal, the first diagnostic signal is low and the second diagnostic signal is high, and the control signal is high.

[0044] It should be noted that, Figure 2 This is a schematic block diagram of a driving circuit shown in an exemplary embodiment of this application, as follows: Figure 2 The driving circuit shown includes a high-side diagnostic unit, a low-side diagnostic unit, a first driving unit, a second driving unit, a first execution unit, and a second execution unit.

[0045] Specifically, the first diagnostic signal output by the high-side diagnostic unit is acquired, and the first diagnostic signal is output by comparator U1. In the high-side diagnostic unit, Vbat is the power supply voltage, VDS is the first fixed standard voltage, R1 is a pull-up resistor, U1 is a voltage comparator, and Q1 is a transistor. The first drive unit provides drive for the first execution unit. The non-inverting input of comparator U1 is connected to the first fixed standard voltage 1VDS. When the first execution unit is open-circuited, the voltage acquired by the inverting input of comparator U1 is close to Vbat, and the output of comparator U1 outputs a high level. When the first execution unit is normally connected, the first execution unit is grounded, and the inverting input of comparator U1 is grounded after being connected in series with the first execution unit, and the output of comparator U1 outputs a low level.

[0046] Specifically, the second drive signal output by the low-side diagnostic unit is acquired, and the second diagnostic signal is output by comparator U2. In the low-side diagnostic unit, VDL is the second fixed standard voltage, R2 is a pull-down resistor, U2 is a comparator, and Q2 is a transistor. The second drive unit provides drive to the second execution unit, and the second execution unit provides power supply voltage Vbat to the low-side diagnostic unit. When the second execution unit is open-circuited or short-grounded, the second execution unit is grounded, the non-inverting input of comparator U2 is grounded, and the output of comparator U2 outputs a low level. When the second execution unit is normally connected, the non-inverting input of comparator U2 is connected to the power supply voltage Vbat, and the output of comparator U2 outputs a high level.

[0047] Specifically, the level of the control signal is determined based on the first diagnostic signal and the second diagnostic signal. When the high-side diagnostic unit diagnoses the first execution unit as having an open circuit abnormality and the low-side diagnostic unit diagnoses the second execution unit as having an open circuit or short ground, the first diagnostic signal is at a high level and the second diagnostic signal is at a low level, so the control signal is at a low level. When the high-side diagnostic unit diagnoses the first execution unit as normal and the low-side diagnostic unit diagnoses the second execution unit as normal, the first diagnostic signal is at a low level and both the second diagnostic signals are at a high level, so the control signal is at a high level.

[0048] In detail, in an exemplary embodiment of this application, the analog signal circuit includes a first analog unit and a second analog unit. In step S110, the control signal of the analog signal circuit is acquired by the control chip, and the level of the control signal is determined, including: acquiring a first reference voltage of the first analog unit and a second reference voltage of the second analog unit; comparing the first reference voltage with the second reference voltage; when the first reference voltage is equal to the second reference voltage, the control signal is at a high level; when the first reference voltage is greater than or less than the second reference voltage, the control signal is at a low level.

[0049] Specifically, Figure 3 This is a schematic diagram of an analog signal circuit illustrated in an exemplary embodiment of this application, such as... Figure 3 As shown, the voltage management integrated unit controls the output of the first reference source and the second reference source. The first analog unit includes a first reference source, resistors R3 and R4, and the second analog unit includes a second reference source, resistors R5 and R6. When the analog signal circuit is working normally, the first reference voltage V1 of the first analog unit is acquired, which is the voltage divider voltage between resistors R3 and R4. The second reference voltage V2 of the second analog unit is also acquired, which is the voltage divider voltage between resistors R5 and R6. Based on the first reference voltage V1 and the second reference voltage V2... A voltage-generated control signal is used to compare a first reference voltage V1 with a second reference voltage V2. If both the first and second reference voltages are 5V, and the first and second reference voltages are equal, the control signal is high. If both the first and second reference voltages are 3V, and the first and second reference voltages are 5V, and the first and second reference voltages are less than the second and second reference voltages, the control signal is low. If both the first and second reference voltages are 5V, and the first and second reference voltages are 2V, and the first and second reference voltages are greater than the second and second reference voltages, the control signal is low.

[0050] In detail, in an exemplary embodiment of this application, in step S110, the control signal of the battery circuit is acquired by the control chip, and the level of the control signal is determined, including: acquiring the voltage value of the power supply voltage in the battery circuit; comparing the voltage value with a preset voltage threshold; if the voltage value is less than the preset voltage threshold, the control signal is at a low level; if the voltage value is equal to the preset voltage threshold, the control signal is at a high level.

[0051] Specifically, Figure 4 This is a schematic block diagram of a battery circuit illustrated in an exemplary embodiment of this application, as shown below. Figure 4 As shown, the battery circuit includes a power supply battery and a backup battery. The power supply battery supplies power to the vehicle's small battery and the first DC power source. The vehicle's small battery provides power to the power management integrated unit. The voltage value of the power supply battery is collected. If the power supply battery or the vehicle's small battery experiences a power supply failure due to a collision or hardware malfunction, the backup battery boosts its voltage through a boost unit to supply power to the power management integrated unit. The voltage value of the power supply battery is also collected. When the voltage value is less than a preset voltage threshold, it indicates an abnormality in the power supply battery or the vehicle's small battery, and the control signal is low. The control signal is transmitted to the control chip through the second DC power source and the communication unit. When the voltage value equals the preset voltage value, it indicates that the vehicle's power supply battery is supplying power normally, and the control signal is high.

[0052] In detail, in an exemplary embodiment of this application, in step S120, the control chip generates a reset signal based on the control signals, including: analyzing the three control signals output by the drive circuit, analog signal circuit, and battery circuit; if one or more of the three control signals are low, the reset signal is low; if all three control signals are high, the reset signal is high. It should be emphasized that by acquiring the three control signals output by the drive circuit, analog signal circuit, and battery circuit, analyzing the levels of the control signals, and if one or more of the three control signals are low, the vehicle safety control mode is triggered, and a reset signal is generated; the reset signal is low. If all three control signals are high, the reset signal is high.

[0053] In detail, in an exemplary embodiment of this application, in step S130, the braking circuit generates a detection signal based on the reset signal, including: when the reset signal is high, switching the detection signal from high to low; the braking circuit sends a stop reset command to the control chip through the high-level reset signal and the low-level detection signal. Specifically, Figure 5This is a schematic diagram of a braking circuit shown in an exemplary embodiment of this application. The braking circuit includes a power management integrated unit and a detection signal generation unit. A reset signal is output through the I / O port of the control chip. Transistor Q3 is a PMOS transistor. When the reset signal is high, transistor Q3 in the detection signal generation unit is cut off. The detection signal is the voltage output from the drain of transistor Q3. The drain of transistor Q3 is grounded through a series resistor R7. The detection signal output by the detection signal generation unit is low. The power management integrated unit acquires the reset signal through the first input terminal F0 and the detection signal through the second input terminal F1. When the reset signal acquired by the power management integrated unit is high and the detection signal is low, the power management integrated unit sends a stop reset command to the control chip. The control chip then normally acquires control signals from multiple circuits.

[0054] In detail, in an exemplary embodiment of this application, in step S140, if the duration of the low-level reset signal and the high-level detection signal is greater than or equal to a preset time threshold, the braking circuit sends a reset command to the control chip. Specifically, if the duration of the reset signal and the detection signal is 1 second, and the preset time threshold is 1 second, then the braking circuit sends a reset command to the control chip; if the duration of the reset signal and the detection signal is 1.2 seconds, and the preset time threshold is 1 second, then the braking circuit sends a reset command to the control chip.

[0055] Specifically, in an exemplary embodiment of this application, if the duration of the low-level reset signal and the high-level detection signal is less than a preset time threshold, the braking circuit sends a stop reset command to the control chip. Specifically, if the duration of the reset signal and the detection signal is 0.5 seconds, and the preset time threshold is 1 second, and the duration of 0.5 seconds is less than the preset time threshold of 1 second, then the braking circuit sends a stop reset command to the control chip.

[0058] The first signal processing module 620 is used to control the chip to generate a reset signal based on the control signal;

[0059] The second signal processing module 630 is used by the braking circuit to generate a detection signal based on the reset signal, and to convert the detection signal from low level to high level when the reset signal is low level.

[0060] The execution module 640 is used to send a reset command to the control chip if the duration of the low-level reset signal and the high-level detection signal is greater than or equal to a preset time threshold.
