Description

Technical Field

[0001] The present application relates to the technical field of power generation, and in particular to a multifunctional control system of a power generation system. Background Art

[0002] As an advanced hybrid vehicle, the power generation system of the extended-range vehicle integrates traditional internal combustion engines and electric drive technology. The system usually includes batteries, energy recovery control systems, internal combustion generators, drive motors, and vehicle transmission systems. The internal combustion generator generates kinetic energy by burning fuel, which is then converted into electrical energy and stored in the battery. At the same time, the drive motor is electrically connected to the vehicle transmission system, which is not only responsible for driving the vehicle, but also converts kinetic energy into electrical energy for storage during braking or deceleration, realizing efficient energy recovery and utilization.

[0003] However, despite the significant technological progress of extended-range vehicles, there are still obvious deficiencies in data processing after vehicle accidents, especially serious accidents such as brake failure. At present, it is difficult for ordinary users and third-party institutions to directly obtain relevant data after vehicle accidents. This inconvenience in data acquisition not only affects the timely and accurate analysis of the cause of the accident, but also hinders the further development and optimization of related safety technologies. Summary of the invention

[0004] The purpose of the present application is to provide a multifunctional control system for a power generation system, which can improve the above-mentioned problems.

[0005] The embodiment of the present application is implemented as follows:

[0006] In the first aspect, the present application provides a multifunctional control system of a power generation system, which is installed on a range-extended vehicle having a power generation system, wherein the power generation system includes a battery, an energy recovery control system, an internal combustion generator, a drive motor, a vehicle transmission system, and a control pedal, wherein the internal combustion generator converts the kinetic energy generated by burning fuel into electrical energy and stores it in the battery, the control pedal is connected to the vehicle transmission system through a mechanical structure, the drive motor is electrically connected to the vehicle transmission system, the drive motor is used to drive the vehicle transmission system to operate, and is used to convert kinetic energy into electrical energy and store it in the battery during braking or deceleration, and the energy recovery control system is used to monitor and adjust the energy recovery state of the power generation system during braking or deceleration. The multifunctional control system includes a first monitoring device, a second monitoring device, and a processor.

[0007] a first monitoring device, detachably mounted around the control pedal, for monitoring pedal operation data of the control pedal;

[0008] A second monitoring device is detachably mounted on the power supply line of the driving motor and is used to monitor first current data of the power supply line;

[0009] A processor is respectively connected to the first monitoring device, the second monitoring device and the energy recovery control system, and the processor is used to execute steps S1 to S3, wherein S1, S2, etc. are only step identifiers, and the execution order of the method is not necessarily in the order of numbers from small to large, for example, step S2 may be executed first and then step S1, and this application does not impose any restrictions.

[0010] S1, judging a brake operation according to the pedal operation data, and judging whether the drive motor is in a driving state or a power generation state according to the first current data;

[0011] S2, receiving energy recovery status fed back by the energy recovery control system;

[0012] S3, if the drive motor does not enter the power generation state within a preset time after the brake operation, and the energy recovery state feedback is a normal state, it is determined that the extended-range vehicle is in a first dangerous state, and a corresponding first safety decision is executed.

[0013] It can be understood that, under normal circumstances, the drive motor should enter the power generation state within a preset time after the brake operation, that is, the energy recovery control system should feedback that the energy recovery state is a normal state. If the drive motor does not enter the power generation state within a preset time after the brake operation, the extended-range vehicle may be in two states: 1. A dangerous state of suspected brake failure; 2. A faulty state of the energy recovery control system. Therefore, if the drive motor does not enter the power generation state within a preset time after the brake operation, and the energy recovery state is fed back as a normal state, then the second situation can be ruled out, and the extended-range vehicle may currently be in the first dangerous state of suspected brake failure.

[0014] It can be understood that the present application proposes a multifunctional control system for an extended-range vehicle, which is detachably mounted on the vehicle as a peripheral. It integrates a first monitoring device, a second monitoring device and a processor, and can monitor the control pedal operation and the state of the drive motor in real time, and judge the brake operation and energy recovery state. When a dangerous state is detected, safety decisions such as recording accident logs are taken. This multifunctional control system can not only detect and intervene in dangerous events in a timely manner, but also effectively improve the safety of extended-range vehicles; at the same time, the accident logs recorded by the system help to accurately analyze the causes of accidents, and provide strong support for the research and development and optimization of automobile safety technology.

[0015] In an optional embodiment of the present application, the first monitoring device includes at least one of the following:

[0016] A pressure sensor, installed on the control pedal, for monitoring force data of the control pedal and using the force data as pedal operation data;

[0017] The displacement sensor is installed on the control pedal or a mechanism directly connected to the control pedal, and is used to detect the movement data of the control pedal and use the movement data as the pedal operation data.

[0018] In an optional embodiment of the present application, judging whether the drive motor is in a driving state or a power generation state based on the first current data includes: judging the current direction of the power supply line based on the first current data; if the current direction is from the drive motor to the vehicle transmission system, judging that the drive motor is in a driving state; if the current direction is from the vehicle transmission system to the drive motor, judging that the drive motor is in a power generation state.

[0019] In an optional embodiment of the present application, if the power generation system also includes a backup energy recovery control system that is enabled when the energy recovery control system fails, the processor is also used to perform the following steps: S4, if the drive motor does not enter the power generation state within a preset time after the braking operation, and the backup energy recovery state feedback is an enabled state, then the extended-range vehicle is in a first dangerous state, and executes a corresponding first safety decision.

[0020] It is understandable that when the energy recovery system in the extended-range vehicle's power generation system fails, the backup energy recovery system will be activated. The processor will monitor the status of the energy recovery system and the backup energy recovery system at the same time, and within a preset time after the brake operation, if the drive motor does not enter the power generation state and the backup energy recovery system has been normally activated, it can be determined that the vehicle is in the first dangerous state of suspected brake failure and execute the corresponding safety decision.

[0021] In an optional embodiment of the present application, the multifunctional control system also includes a first physical disconnection device electrically connected to the processor, the first physical disconnection device being installed around the drive motor and being used to disconnect the power supply line through a mechanical structure under the drive of a first disconnection control instruction; the first safety decision includes issuing the first disconnection control instruction to the first physical disconnection device.

[0022] It can be understood that the introduction of the first physical disconnection device can quickly disconnect the power supply line through the mechanical structure when the processor issues the first disconnection control instruction. This provides a direct physical protection method for the system, which can immediately cut off the power supply when a serious dangerous state is detected, such as abnormal acceleration of the drive motor, brake failure, etc., to prevent the accident from expanding.

[0023] In an optional embodiment of the present application, the multifunctional control system also includes a communication module electrically connected to the processor; the first safety decision includes at least one of the following: alerting a preset terminal through the communication module; generating a first accident log based on feedback data from the first monitoring device, the second monitoring device and the energy recovery control system, and sending the first accident log to the preset terminal through the communication module.

[0024] It is understood that the above-mentioned preset terminal can be the terminal device of the car owner, or the terminal device of the family / friend designated by the car owner, or an official terminal device. The communication module enhances the remote interaction capability of the system. Once a dangerous state occurs, the system will not only remind the user in the car through the interactive device, but also send an alarm message to the preset terminal and transmit the accident log containing key data to it.

[0025] In an optional embodiment of the present application, the processor is also connected to an interactive device of the extended-range vehicle, and the processor is also used to display and / or express at least one of the following through the interactive device: the first dangerous state; the first safety decision.

[0026] It can be understood that interactive devices, such as display screens or sound prompts, intuitively show the car's dangerous state and safety decisions to the owner. For example, when an abnormality in the brake system is detected, the display screen will immediately display a warning message and suggest safety measures for the owner, such as slowing down, pulling over, etc. This greatly improves the owner's perception and response speed to the car's state, and helps to ensure the owner's safety in an emergency.

[0027] In a second aspect, the present application provides another multifunctional control system for a power generation system, which is different from the multifunctional control system disclosed in the first aspect in that a third monitoring device is added, and the third monitoring device is detachably mounted on a power supply line connecting the internal combustion generator and the battery, and is used to monitor second current data of the power supply line;

[0028] The processor is used to execute steps S5 to S8, where S5, S6, etc. are only step identifiers, and the execution order of the method is not necessarily in the order of numbers from small to large. For example, step S6 may be executed first and then step S5. This application does not impose any restrictions.

[0030] S6, determining a second current value of the power supply line according to the second current data;

[0031] S7, judging whether the power generation system is in a second dangerous state according to the first current value and the second current value;

[0032] S8: If it is determined that the power generation system is in a second dangerous state, a corresponding second safety decision is executed.

[0033] It can be understood that the present application also provides another multifunctional control system for a power generation system, in which a third monitoring device is added on the basis of the multifunctional control system disclosed in the first aspect, and the third monitoring device is installed on the power supply line connecting the internal combustion generator and the battery, and is specifically used to monitor the second current data of the power supply line. This design is mainly to monitor the current state of the power generation system more comprehensively, especially focusing on the current generated by the internal combustion generator and the current converted by the drive motor in the power generation state, so as to prevent these currents from being too large and exceeding the safe charging threshold of the battery, thereby avoiding dangerous situations such as battery overheating, damage and even spontaneous combustion. This multifunctional control system provides comprehensive monitoring of the current state of the power generation system, which can promptly detect and prevent battery safety problems caused by excessive current, thereby effectively improving the overall safety of the extended-range vehicle. At the same time, through timely alarms and reminders, it also helps the owner to take countermeasures quickly in an emergency to avoid accidents.

[0034] In an optional embodiment of the present application, the S7 includes at least one of the following:

[0035] When the first current value exceeds a first current safety threshold, determining that the power generation system is in a second dangerous state;

[0036] When the second current value exceeds a second current safety threshold, determining that the power generation system is in a second dangerous state;

[0037] When the sum of the first current value and the second current value exceeds a third current safety threshold, it is determined that the power generation system is in a second dangerous state.

[0038] In an optional embodiment of the present application, the multifunctional control system also includes a second physical disconnection device electrically connected to the processor, and the second physical disconnection device is installed around the drive motor, and is used to disconnect the power line through a mechanical structure under the drive of a second disconnection control instruction; the second safety decision includes issuing the second disconnection control instruction to the second physical disconnection device.

[0039] It can be understood that a second physical disconnection device is added to the multifunctional control system, which can quickly disconnect the power line of the drive motor when the processor issues a second disconnection control instruction. This design enhances the physical protection capability of the system when the second dangerous state is detected, and can effectively prevent the accident from expanding. For example, when the current is too large and may cause the battery to overheat or be damaged, the system can immediately cut off the power supply to ensure the safety of the vehicle and passengers.

[0040] In an optional embodiment of the present application, the multifunctional control system further comprises a communication module electrically connected to the processor;

[0041] The second security decision includes at least one of the following:

[0042] Alarming a preset terminal via the communication module;

[0043] A second accident log is generated according to feedback data from the first monitoring device and the third monitoring device, and the second accident log is sent to a preset terminal through the communication module.

[0044] It can be understood that the remote interaction capability of the multifunctional control system is enhanced by introducing the communication module. When the second dangerous state is detected, the system can not only remind the user in the car through the interactive device, but also send an alarm message to the preset terminal and transmit the accident log containing key data. This helps the owner or relevant personnel to understand the vehicle status in time and take countermeasures quickly to avoid accidents or their expansion.

[0045] In an optional embodiment of the present application, the processor is also connected to an interactive device of the extended-range vehicle, and the processor is also used to display and / or express at least one of the following through the interactive device: the second dangerous state; the second safety decision.

[0046] It can be understood that by displaying and / or showing the second dangerous state and the second safety decision through the interactive device of the extended-range vehicle, the owner can more intuitively understand the dangerous state and safety decision of the vehicle, and improve the perception and response speed of the vehicle state. In an emergency, this helps the owner to quickly take correct safety measures to ensure the safety of himself and the vehicle.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] First, as Figure 1As shown, the present application provides a multifunctional control system 100 of a power generation system 10, which is installed on an extended-range vehicle having the power generation system 10, wherein the power generation system 10 includes a battery 11, an energy recovery control system 12, an internal combustion generator 13, a drive motor 14, a vehicle transmission system 15, and a control pedal 16. The internal combustion generator 13 converts the kinetic energy generated by burning fuel into electrical energy and stores it in the battery 11. The control pedal 16 is connected to the vehicle transmission system 15 through a mechanical structure. The drive motor 14 is electrically connected to the vehicle transmission system 15. The drive motor 14 is used to drive the vehicle transmission system 15 to operate, and is used to convert kinetic energy into electrical energy and store it in the battery 11 during braking or deceleration. The energy recovery control system 12 is used to monitor and adjust the energy recovery state of the power generation system 10 during braking or deceleration. The multifunctional control system 100 includes a first monitoring device 101, a second monitoring device 102, and a processor 103.

[0057] The first monitoring device 101 is detachably mounted around the control pedal 16 and is used to monitor pedal operation data of the control pedal 16 .

[0058] The second monitoring device 102 is detachably mounted on the power supply line of the drive motor 14 and is used to monitor the first current data of the power supply line.

[0059] The processor 103 is connected to the first monitoring device 101, the second monitoring device 102 and the energy recovery control system 12 respectively. The processor 103 is used to execute steps S1 to S3, wherein S1, S2, etc. are only step identifiers, and the execution order of the method is not necessarily in the order of numbers from small to large. For example, step S2 may be executed first and then step S1. This application does not impose any restrictions.

[0060] S1, judging the brake operation according to the pedal operation data, and judging whether the drive motor 14 is in the driving state or the power generation state according to the first current data.

[0061] In an optional embodiment of the present application, determining whether the drive motor 14 is in a driving state or a power generation state is based on the first current data, including: determining the current direction of the power supply line based on the first current data; if the current direction is from the drive motor 14 to the vehicle transmission system 15, determining that the drive motor 14 is in a driving state; if the current direction is from the vehicle transmission system 15 to the drive motor 14, determining that the drive motor 14 is in a power generation state.

[0062] S2, receiving the energy recovery status fed back by the energy recovery control system.

[0063] In the embodiment of the present application, the energy recovery control system is the core component of the extended-range hybrid vehicle. It realizes the efficient recovery and utilization of kinetic energy during the braking or deceleration of the vehicle through the coordinated work of sensors, controllers, actuators and integrated status monitoring modules. The sensors monitor the key parameters of the vehicle in real time, such as speed, acceleration, motor current and voltage, and provide the necessary data input for the controller. As the "brain" of the system, the controller receives and analyzes these data, determines whether the current working conditions are suitable for energy recovery, calculates the amount of energy to be recovered, and issues instructions to the actuator to adjust the power generation of the motor and the degree of intervention of the braking system. The actuator accurately controls the working state of the motor and the braking system according to the instructions of the controller to achieve efficient energy recovery. The status monitoring module monitors the operating state and performance parameters of the system in real time to ensure the stable operation of the system and the safety of the vehicle. Through the coordinated work of this system, the extended-range hybrid vehicle can convert kinetic energy into electrical energy and store it during braking or deceleration, which improves the energy utilization efficiency of the whole vehicle, and also helps to extend the battery life and reduce the wear of the braking system. This innovative technology not only improves the environmental performance of the vehicle, but also brings users a more economical and efficient driving experience.

[0064] S3: If the driving motor does not enter the power generation state within a preset time after the braking operation, and the energy recovery state feedback is normal, it is determined that the extended-range vehicle is in a first dangerous state, and the corresponding first safety decision is executed.

[0065] It can be understood that, under normal circumstances, the drive motor 14 should enter the power generation state within a preset time after the brake operation, that is, the energy recovery control system 12 should feedback that the energy recovery state is a normal state. If the drive motor 14 does not enter the power generation state within a preset time after the brake operation, the extended-range vehicle may be in two states: 1. A dangerous state of suspected brake failure; 2. A faulty state of the energy recovery control system 12. Therefore, if the drive motor 14 does not enter the power generation state within a preset time after the brake operation, and the energy recovery state is fed back as a normal state, then the second situation can be ruled out, and the extended-range vehicle may currently be in the first dangerous state of suspected brake failure.

[0066] It can be understood that the present application proposes a multifunctional control system 100 for an extended-range vehicle, which is detachably mounted on the vehicle as a peripheral. It integrates a first monitoring device 101, a second monitoring device 102 and a processor 103, and can monitor the operation of the control pedal 16 and the state of the drive motor 14 in real time, and judge the braking operation and energy recovery state. When a dangerous state is detected, safety decisions such as recording an accident log are taken. This multifunctional control system 100 can not only detect and intervene in dangerous events in a timely manner, effectively improving the safety of extended-range vehicles; at the same time, the accident logs recorded by the system help to accurately analyze the causes of accidents, providing strong support for the research and development and optimization of automobile safety technologies.

[0069] The displacement sensor is installed on the control pedal 16 or a mechanism directly connected to the control pedal 16, and is used to detect the movement data of the control pedal 16 and use the movement data as pedal operation data.

[0070] In an optional embodiment of the present application, if Figure 2 As shown, if the power generation system 10 also includes a backup energy recovery control system 17 that is enabled when the energy recovery control system 12 fails, the processor 103 is also used to perform the following steps: S4, if the drive motor 14 does not enter the power generation state within a preset time after the braking operation, and the backup energy recovery state feedback is an enabled state, the extended-range vehicle is in a first dangerous state, and the corresponding first safety decision is executed.

[0071] It is understood that when the energy recovery system fails in the power generation system 10 of the extended-range vehicle, the backup energy recovery system will be activated. The processor 103 will monitor the status of the energy recovery system and the backup energy recovery system at the same time, and within a preset time after the brake operation, if the drive motor 14 does not enter the power generation state and the backup energy recovery system has been normally activated, it can be determined that the vehicle is in the first dangerous state of suspected brake failure, and the corresponding safety decision will be executed.

[0072] In the optional embodiment of the present application, continue to refer to Figure 1 The multifunctional control system 100 also includes a first physical disconnection device 104 electrically connected to the processor 103.

[0073] It can be understood that the introduction of the first physical disconnection device 104 can quickly disconnect the power supply line through a mechanical structure when the processor 103 issues a first disconnection control instruction. This provides a direct physical protection means for the system, which can immediately cut off the power supply when a serious dangerous state is detected, such as abnormal acceleration of the drive motor 14, brake failure, etc., to prevent the accident from expanding.

[0074] In the optional embodiment of the present application, continue to refer to Figure 1 The multifunctional control system 100 also includes a communication module 105 electrically connected to the processor 103; the first safety decision includes at least one of the following: alerting a preset terminal through the communication module 105; generating a first accident log based on feedback data from the first monitoring device 101, the second monitoring device 102 and the energy recovery control system 12, and sending the first accident log to the preset terminal through the communication module 105.

[0075] It is understood that the above-mentioned preset terminal can be the terminal device of the car owner, or the terminal device of the family / friend designated by the car owner, or it can also be an official terminal device. The communication module 105 enhances the remote interaction capability of the system. Once a dangerous state occurs, the system will not only remind the user in the car through the interactive device 1, but also send an alarm message to the preset terminal and transmit the accident log containing key data to it.

[0076] In the optional embodiment of the present application, continue to refer to Figure 1 The processor 103 is also connected to the interactive device 1 of the extended-range vehicle, and the processor 103 is also used to display and / or express at least one of the following through the interactive device: a first dangerous state; a first safety decision.

[0077] It can be understood that the interactive device 1, such as a display screen or sound prompt, intuitively displays the dangerous state of the car and safety decisions to the car owner. For example, when an abnormality in the brake system is detected, the display screen will immediately display a warning message and suggest safety measures to the car owner, such as slowing down, pulling over, etc. This greatly improves the car owner's perception and response speed to the car state, which helps to ensure the safety of the car owner in an emergency.

The difference compared with the multifunctional control system 100 disclosed in the first aspect is that a third monitoring device 205 is added, and the third monitoring device 205 is detachably installed on the power supply line connecting the internal combustion generator 13 and the battery 11, and is used to monitor the second current data of the power supply line.

[0079] Processor 203 is used to execute steps S5 to S8, where S5, S6, etc. are only step identifiers, and the execution order of the method is not necessarily in the order of numbers from small to large. For example, step S6 may be executed first and then step S5. This application does not impose any restrictions.

[0083] S8: If it is determined that the power generation system is in a second dangerous state, a corresponding second safety decision is executed.

[0084] It can be understood that the present application also provides another multifunctional control system 200 for a power generation system. A third monitoring device 205 is added on the basis of the multifunctional control system 200 disclosed in the first aspect. The third monitoring device 205 is installed on the power supply line connecting the internal combustion generator 13 and the battery 11, and is specifically used to monitor the second current data of the power supply line. This design is mainly to more comprehensively monitor the current state of the power generation system, especially to pay attention to the current generated by the internal combustion generator 13 and the current converted by the drive motor 14 in the power generation state, so as to prevent these currents from being too large and exceeding the safe charging threshold of the battery 11, thereby avoiding dangerous situations such as overheating, damage or even spontaneous combustion of the battery 11. The multifunctional control system 200 provides comprehensive monitoring of the current state of the power generation system, which can timely discover and prevent safety problems of the battery 11 caused by excessive current, thereby effectively improving the overall safety of the extended-range vehicle. At the same time, through timely alarms and reminders, it also helps the owner to quickly take countermeasures in an emergency to avoid accidents.

[0088] When the sum of the first current value and the second current value exceeds the third current safety threshold, it is determined that the power generation system is in a second dangerous state.

[0089] In the optional embodiment of the present application, continue to refer to Figure 3The multifunctional control system 200 also includes a second physical disconnection device 206 electrically connected to the processor 203. The second physical disconnection device 206 is installed around the drive motor 14 and is used to disconnect the power line through a mechanical structure under the drive of a second disconnection control instruction; the second safety decision includes issuing a second disconnection control instruction to the second physical disconnection device 206.

[0090] It can be understood that a second physical disconnection device 206 is added to the multifunctional control system 200, which can quickly disconnect the power line of the drive motor 14 when the processor 203 issues a second disconnection control instruction. This design enhances the physical protection capability of the system when the second dangerous state is detected, and can effectively prevent the accident from expanding. For example, when the current is too large and may cause the battery 11 to overheat or be damaged, the system can immediately cut off the power supply to ensure the safety of the vehicle and passengers.

[0091] In an optional embodiment of the present application, the multifunctional control system 200 further includes a communication module 207 electrically connected to the processor 203;

[0094] A second accident log is generated according to the feedback data from the first monitoring device and the third monitoring device 205 , and the second accident log is sent to a preset terminal through the communication module 207 .

[0095] It can be understood that by introducing the communication module 207, the remote interaction capability of the multifunctional control system 200 is enhanced. When the second dangerous state is detected, the system can not only remind the user in the car through the interactive device 1, but also send an alarm message to the preset terminal and transmit the accident log containing key data. This helps the owner or relevant personnel to understand the vehicle status in time and take countermeasures quickly to avoid accidents or their expansion.

[0096] In an optional embodiment of the present application, the processor 203 is also connected to the interactive device 1 of the extended-range vehicle, and the processor 203 is also used to display and / or express at least one of the following through the interactive device: a second dangerous state; a second safety decision.

[0097] It can be understood that by displaying and / or representing the second dangerous state and the second safety decision through the interactive device 1 of the extended-range vehicle, the owner can more intuitively understand the dangerous state and safety decision of the vehicle, thereby improving the perception and response speed of the vehicle state. In an emergency, this helps the owner to quickly take correct safety measures to ensure the safety of himself and the vehicle.

[0098] It should be understood that in the embodiments of the present invention, the processor may be a central processing unit (CPU), and the processor may also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc.

[0099] The expressions "first", "second", "the first" or "the second" used in various embodiments of the present disclosure may modify various components regardless of order and / or importance, but these expressions do not limit the corresponding components. The above expressions are only configured for the purpose of distinguishing an element from other elements.
