Description

Technical Field

[0001] The present invention relates to the automotive field, and in particular to a hybrid electric vehicle motor controller power supply architecture and a hybrid electric vehicle control method. Background Art

[0002] With the rapid development of the new energy vehicle industry, pure electric vehicles are facing a bottleneck in their adoption due to insufficient range and limited charging efficiency. Traditional fuel-powered vehicles, however, are constrained by high energy costs and low electrification levels, making them unable to meet the demands for intelligence and comfort. Against this backdrop, hybrid vehicles, which combine the convenience of fuel replenishment with the advantages of electrification, have become a key market development direction.

[0003] However, existing hybrid vehicle motor controllers have inherent flaws. Typically, a hybrid vehicle motor controller includes three functional module power supplies: a voltage regulator module, a generator module, and a driver module. These three modules are typically connected in parallel to a single low-voltage power supply line. If any module short-circuits or overloads, the fault propagates, causing the low-voltage line to disconnect protectively, leading to a simultaneous loss of power to all functional module power supplies. This results in, on the one hand, the vehicle becoming completely disabled if a single module fails, potentially posing a dangerous hazard on highways. On the other hand, the vehicle cannot reach a repair station on its own and must rely on external assistance to be transported there. This significantly increases operational costs and time, creating maintenance cost-effectiveness issues.

[0004] In summary, there is currently no good solution to these problems. Summary of the Invention

[0005] In order to overcome the above technical deficiencies, the present invention aims to provide a hybrid electric vehicle motor controller power supply architecture and a hybrid electric vehicle control method.

Each of the three short-circuit protection devices has one end electrically connected to the low-voltage input power supply and the other end electrically connected to the voltage regulating module power supply, the power generation module power supply or the drive module power supply; so that when one module power supply fails, the corresponding short-circuit protection device is disconnected and the power supplies of the remaining modules are not affected.

[0007] Preferably, the protection module includes a first short-circuit protection device, a second short-circuit protection device, a third short-circuit protection device, and a fourth short-circuit protection device; The first short-circuit protection device is electrically connected to the front axle voltage regulating power supply; The second short-circuit protection device is electrically connected to the rear axle voltage regulating power supply; The third short-circuit protection device is electrically connected to the power supply of the power generation module; The fourth short-circuit protection device is electrically connected to the lower bridge driving power supply.

[0008] Preferably, the power supply architecture further includes an emergency input power supply, which is electrically connected to the lower bridge drive power supply, the front bridge voltage regulating power supply, and the rear bridge voltage regulating power supply.

[0009] Preferably, the short-circuit protection device is an electronic fuse.

[0010] The present application also provides a hybrid vehicle control method, wherein the vehicle includes an engine, a battery, a motor, and a motor controller; the engine is connected to a generator, which is electrically connected to the battery; the battery is also connected to the motor controller; the motor controller includes a power supply architecture as described in any of the above embodiments, and is electrically connected to the generator, the battery, and the motor; When the lower bridge drive power supply fails, the lower bridge drive power supply is disconnected from the low voltage input power supply; the low voltage input power supply supplies power to the upper bridge drive power supply to drive the motor through the upper bridge drive power supply.

[0011] Preferably, when the power supply architecture includes an emergency input power supply: When the power supply architecture includes an emergency input power supply: When the upper bridge drive power supply fails, the low voltage input power supply also fails; the emergency input power supply supplies power to the lower bridge drive power supply and the voltage regulating module power supply, so as to control the motor to stop through the lower bridge drive power supply, and connect the high voltage of the motor controller with the battery through the voltage regulating module to prevent the reverse current generated during the gradual stop of the motor from damaging the motor controller.

[0012] Preferably, when the power supply of the power generation module fails, the power supply of the power generation module is disconnected from the low voltage input power supply; The low voltage input power supplies the voltage regulator module to control the battery to supply power to the motor; The low voltage input power supplies the drive module power supply to control and drive the motor.

[0013] Preferably, when the front axle voltage regulating power supply fails, the front axle voltage regulating power supply is disconnected from the low-voltage input power supply; the low-voltage input power supply supplies power to the rear axle voltage regulating power supply; the rear axle voltage regulating power supply regulates the voltage to supply power to the motor and causes the motor to operate below peak power; When the rear axle voltage regulating power supply fails, the rear axle voltage regulating power supply is disconnected from the low-voltage input power supply; the low-voltage input power supply supplies power to the front axle voltage regulating power supply, and the front axle voltage regulating power supply regulates the voltage to power the motor and makes the motor run below the peak power.

[0014] Preferably, when the front axle voltage regulating power supply fails, the rear axle voltage regulating power supply supplies power to the motor by half-wave boosting; When the rear axle voltage regulating power supply fails, the front axle voltage regulating power supply supplies power to the motor through a half-wave boost method.

[0015] Preferably, when the front axle voltage regulating power supply or the rear axle voltage regulating power supply fails, the power generation module controls the generator so that the generator and the rear axle voltage regulating power supply or the front axle voltage regulating power supply jointly power the motor.

[0016] Compared with the existing technology, the above technical solution has the following beneficial effects: 1. This application achieves electrical decoupling between the voltage regulating module power supply, the power generation module power supply, and the drive module power supply by protecting multiple independently provided short-circuit protection devices in the module power supply. When an overload or short-circuit fault occurs in any functional module power supply, only the corresponding specific short-circuit protection device is triggered to disconnect, completely eliminating the risk of the fault being transmitted to the low-voltage input power supply and other functional module power supplies. This fundamentally solves the problem of the entire vehicle's low-voltage system being paralyzed due to a single module power supply failure, and gives the vehicle the ability to autonomously move to a repair station after the power generation module power supply or the voltage regulating module power supply fails, significantly reducing rescue dependence and operation and maintenance costs; 2. Furthermore, based on the refined setting of the short-circuit protection device, it can be achieved that: 1. The voltage regulating module power supply adopts a front and rear axle dual power supply architecture. When a single bridge arm voltage regulating power supply fails, the low-voltage input power supply can power the other normal bridge arm power supply, maintain the battery buck-boost control function, and realize low-power operation mode; 2. When the power supply of the power generation module fails, the motor controller immediately cuts off the power supply link of the module power supply, and switches the low-voltage input power supply to the drive module power supply and the voltage regulating module power supply, switching to pure battery drive mode to ensure basic driving capability; 3. When the upper bridge drive power supply fails, the entire low-voltage input power supply and the power generation module power supply are turned off, and then the lower bridge drive power supply is independently powered by an independent emergency input power supply, ensuring that the vehicle can enter a safe parking mode, avoiding the reverse damage of the motor and battery caused by the pressure difference caused by the motor reversal; and a resettable electronic fuse is also used as a short-circuit protection device. After the fault is eliminated, the connection can be restored remotely or automatically, avoiding the maintenance time and component loss cost caused by the replacement of traditional fusible fuses.

[0017] 3. A dynamic vehicle energy scheduling strategy, based on the aforementioned power architecture, translates into a complete vehicle operating mode. In the event of a drive power failure, the power supply path is switched based on the position of the failed bridge arm. If the upper bridge fails, the emergency input power source takes over driving the lower bridge. If the lower bridge fails, the low-voltage main power source maintains operation of the upper bridge, maintaining at least single-bridge drive capability. This allows the vehicle to stop smoothly and protects the motor and battery. In the event of a power failure in the generator module, pure electric drive maintains power, enabling autonomous movement to a repair point without external assistance. Finally, in the event of a power failure in the voltage regulator module, low-power output from the battery is achieved through a single bridge, maintaining vehicle mobility. Furthermore, single-phase boost control compensates for the voltage demand of the voltage regulator module, enabling the core electrical system to operate even in a derated operating mode. This coordinated control mechanism ensures that the vehicle maintains basic driving functions despite multiple fault conditions, completely avoiding the risk of high-speed stall and maximizing the drivable range after a fault.

[0025] See also Figure 1 , Figure 1 This is a schematic diagram of the power supply architecture and control components of the hybrid vehicle motor controller provided in this application.

[0026] like Figure 1 As shown, the present invention discloses a hybrid electric vehicle motor controller power supply architecture, including: Voltage regulating module power supply, the voltage regulating module power supply includes front axle voltage regulating power supply and rear axle voltage regulating power supply; Power generation module power supply, the power generation module power supply includes an upper bridge power generation power supply and a lower bridge power generation power supply; Drive module power supply, which includes upper bridge drive power supply and lower bridge drive power supply; A low-voltage input power supply, the low-voltage input power supply is electrically connected to the voltage regulating module power supply, the power generation module power supply and the drive module power supply; The protection module includes at least three short-circuit protection devices. Each of the three short-circuit protection devices has one end electrically connected to the low-voltage input power supply and the other end electrically connected to the voltage regulating module power supply, the power generation module power supply or the drive module power supply; so that when one module power supply fails, the corresponding short-circuit protection device is disconnected and the power supplies of the remaining modules are not affected.

[0027] It can be understood here that three module power supplies are provided in the motor controller of the car, namely: a voltage regulating module power supply connected to the power battery for increasing the power battery voltage (for example, increasing a battery of about 300V-400V to 500V-600V, thereby obtaining better motor power and energy consumption performance), a power generation module power supply for driving the generator so that the engine can drive the generator to generate electricity (the type of engine here is not limited, it can be used only as a generator, or it can be used as both a generator and a power source, and this application is not limited here) and a drive module power supply for driving the motor.

[0028] The multiple independently arranged short-circuit protection devices in the protection module of this application realize the electrical decoupling between the voltage regulating module power supply, the power supply of the power generating module and the power supply of the driving module. When an overload or short-circuit fault occurs in the power supply of any functional module, only the corresponding specific short-circuit protection device is triggered to disconnect, completely eliminating the risk of the fault being transmitted to the low-voltage input power supply and the power supply of other functional modules. This fundamentally solves the problem of the entire vehicle's low-voltage system being paralyzed due to the failure of a single module power supply, and gives the vehicle the ability to move autonomously to a maintenance station after the power supply of the power generating module or the voltage regulating module fails, greatly reducing rescue dependence and operation and maintenance costs.

[0029] The above is an explanation of the basic principles of this application. The following will describe in detail the specific possible power supply architecture design with reference to the accompanying drawings.

[0030] It should be noted that the motor controller may include more or fewer devices than the aforementioned ones. For example, as shown in the figure, the hybrid vehicle motor controller power supply architecture provided in this application is to supply power to the driver chips corresponding to each module power supply (such as the Boost_F upper bridge driver chip in the figure, etc.), thereby controlling various components of the entire vehicle through the driver chips.

[0031] Furthermore, it is understandable that the power supplies of each module do not directly participate in the subsequent control of the various components of the vehicle. The power modules (for example, the voltage regulating module corresponding to the voltage regulating module power supply, etc.) still control the various components of the vehicle. However, this application mainly focuses on circuit design and solutions after the power supply of each module fails. Therefore, the modules themselves will not be described in detail here, but only the control method of the module power supply will be explained.

[0032] The specific implementation of the low-voltage input power supply is also not limited, such as Figure 1 As shown, in a possible implementation, the low-voltage input power supply is realized through a KL30 (in a possible implementation, it can be understood as the positive pole of the car battery) through a voltage regulator.

[0033] like Figure 1 As shown, further, the protection module includes a first short-circuit protection device, a second short-circuit protection device, a third short-circuit protection device, and a fourth short-circuit protection device; The first short-circuit protection device is electrically connected to the front axle voltage regulating power supply; The second short-circuit protection device is electrically connected to the rear axle voltage regulating power supply; The third short-circuit protection device is electrically connected to the power supply of the power generation module; The fourth short-circuit protection device is electrically connected to the lower bridge driving power supply.

[0034] This can be understood as follows: the front-axle and rear-axle voltage-regulating power supplies of the voltage-regulating module are each equipped with a short-circuit protection device. The entire power generation module power supply corresponds to a short-circuit protection device. In the driver module power supply, only the lower-axle driver power supply and the low-voltage power supply are connected via a short-circuit protection device. The upper-axle driver power supply is directly connected to the low-voltage power supply.

[0035] The purpose of such refined settings is to: 1. The voltage regulator module adopts a dual power supply architecture for the front and rear axles. When a single bridge arm voltage regulator fails, the low-voltage input power supply can power the other normal bridge arm power supply, maintaining the battery buck-boost control function and achieving low-power operation mode. Second, if the power supply of the power generation module fails, the motor controller immediately disconnects the power supply link of the module and switches the low-voltage input power supply to the power supply of the drive module and the voltage regulator module, switching to pure battery drive mode to ensure basic driving capability. Therefore, there is no need to further decouple the power supply of the power generation module, and the car can operate normally; 3. When the lower bridge drive power supply fails, disconnect the lower bridge drive power supply, and the power supply of other modules will not be affected.

[0036] Fourth, with lower hardware costs, the power supply of each module of the motor controller is decoupled, thereby maximizing the robustness of vehicle driving while meeting functional safety requirements.

[0037] Furthermore, the power supply architecture also includes an emergency input power supply, which is electrically connected to the lower bridge drive power supply, the front bridge voltage regulating power supply, and the rear bridge voltage regulating power supply.

[0038] This can be understood as follows: the lower bridge drive power supply is electrically connected to the low-voltage input power supply via a fourth short-circuit protection device, thereby providing power; and a separate emergency input power supply is also provided for it. Therefore, if the upper bridge drive power supply fails, the entire low-voltage input power supply and the power supply of the power generation module are shut down, and then the independent emergency input power supply is used to supply power to the lower bridge drive power supply and voltage regulator power supply, ensuring that the vehicle can enter a safe parking mode and preventing the reverse voltage difference caused by motor reversal from damaging the motor and battery.

[0039] Those skilled in the art will appreciate that the specific implementation of the short-circuit protection device in any of the aforementioned embodiments is not limited.

[0040] In a possible implementation, the short circuit protection device may be a conventional fuse. Figure 1 As shown, in another possible implementation, the short-circuit protection device is preferably an electronic fuse. By using a resettable electronic fuse as the short-circuit protection device, the connection can be restored remotely or automatically after the fault is eliminated, avoiding the time-consuming maintenance and component loss costs associated with replacing traditional blown fuses.

[0041] The above is a detailed description of the hybrid electric vehicle motor controller power supply architecture provided by this application. The following describes the vehicle control method corresponding to this power supply architecture.

[0042] See also Figure 2-Figure 6 , Figure 2-Figure 3 This is a schematic diagram of the architecture of the hybrid vehicle motor controller power supply architecture provided by this application when the voltage regulator module has a power failure; Figure 4 This is a schematic diagram of the hybrid vehicle motor controller power architecture provided by this application when the power supply of the power generation module fails; Figure 5-Figure 6 This is a schematic diagram of the hybrid vehicle motor controller power architecture provided in this application when the drive module power supply fails.

[0043] like Figures 1-6 As shown, the present application also provides a hybrid vehicle control method, wherein the vehicle includes an engine, a generator, a battery, a motor, and a motor controller; the engine is connected to the generator; the battery is electrically connected to the motor; the motor controller includes a power supply architecture as described in any of the above embodiments, and is electrically connected to the engine, the battery, and the motor; When the lower bridge drive power supply fails, the lower bridge drive power supply is disconnected from the low voltage input power supply; the low voltage input power supply supplies power to the upper bridge drive power supply to drive the motor through the upper bridge drive power supply.

[0044] Preferably, when the power architecture includes an emergency input power supply: When the upper bridge drive power supply fails, the low voltage input power supply also fails; the emergency input power supply supplies power to the lower bridge drive power supply and the voltage regulating module power supply, so as to control the motor to stop through the lower bridge drive power supply, and connect the high voltage of the motor controller with the battery through the voltage regulating module to prevent the reverse current generated during the gradual stop of the motor from damaging the motor controller.

[0045] The principle behind this is explained: if either the upper or lower bridge drive power supply fails, the vehicle can no longer drive the motor using a single power supply alone. However, a secondary power supply is still required to ensure a smooth motor stop and safe braking. When the battery no longer drives the motor in the forward direction, a significant back EMF is generated at the wheel. If this energy enters the motor controller unchecked, it could cause a reverse overshoot and damage the controller. Therefore, the voltage regulator module can be understood as channeling this back EMF, creating a controlled path for the wheel-end back EMF energy to flow through the motor controller and then into the battery. This prevents damage to the motor controller due to reverse overshoot, reducing repair costs and improving the overall vehicle's maintenance efficiency.

[0046] The above is the control method of the car after the drive module power failure.

[0047] Furthermore, when the power supply of the power generation module fails, the power supply of the power generation module is disconnected from the low voltage input power supply; The low voltage input power supplies the voltage regulator module to control the battery to supply power to the motor; The low voltage input power supplies the drive module power supply to control and drive the motor.

[0048] Furthermore, when the front axle voltage regulating power supply fails, the front axle voltage regulating power supply is disconnected from the low voltage input power supply; the low voltage input power supply supplies power to the rear axle voltage regulating power supply; the rear axle voltage regulating power supply regulates the voltage to supply power to the motor and causes the motor to operate below peak power; When the rear axle voltage regulating power supply fails, the rear axle voltage regulating power supply is disconnected from the low-voltage input power supply; the low-voltage input power supply supplies power to the front axle voltage regulating power supply, and the front axle voltage regulating power supply regulates the voltage to power the motor and makes the motor run below the peak power.

[0049] Those skilled in the art will appreciate that, when any voltage-regulating power source fails, the specific manner of using another voltage-regulating power source to control the battery is not limited.

[0050] like Figure 1-Figure 3 As shown, in a possible implementation, when the front axle voltage regulating power supply fails, the rear axle voltage regulating power supply supplies power to the motor by half-wave boosting; When the rear axle voltage regulating power supply fails, the front axle voltage regulating power supply supplies power to the motor through a half-wave boost method.

[0051] This can be understood as follows: through the half-wave boost method, when one voltage-regulating power supply fails, the other voltage-regulating power supply can still make the battery work through the half-wave boost method, but it runs at lower than the standard power, still maintaining some mobility of the car.

[0052] Furthermore, when the front axle voltage regulating power supply or the rear axle voltage regulating power supply fails, the power generation module controls the generator so that the generator and the rear axle voltage regulating power supply or the front axle voltage regulating power supply jointly power the motor.

[0053] This can be understood as follows: when the voltage-regulated power supply module only has one regulated power supply operating, in order to maintain a constant voltage for normal motor operation, it needs to run twice as long, using a half-wave boost method to boost the battery voltage. This causes the regulated power supply to heat up quickly, forcing it to operate at reduced power. In this case, the generator can be controlled by the power supply of the power generation module, and the power generated by the generator can also be connected to the circuit to power the motor. This not only reduces the pressure on the regulated power supply, but also ensures more stable operation. Furthermore, the combined power supply of the two provides a stronger output capacity than if the motor were powered solely by the regulated power supply, alleviating the problem of motor power limitation and enhancing the vehicle's mobility.

[0054] In summary, the vehicle's dynamic energy scheduling strategy, based on the aforementioned power supply architecture, translates into a complete vehicle operating mode: In the event of a drive power failure, the power supply path is switched based on the position of the failed bridge arm. If the upper bridge fails, the emergency input power source takes over driving the lower bridge. If the lower bridge fails, the low-voltage main power source maintains operation of the upper bridge, maintaining at least single-bridge drive capability at all times, allowing the vehicle to stop smoothly and protecting the motor and battery. Furthermore, in the event of a power failure in the generator module, pure electric drive maintains power, enabling autonomous movement to a repair point without external assistance. Finally, in the event of a power failure in the voltage regulator module, a single bridge achieves low-power output from the battery, maintaining some mobility. Furthermore, single-phase boost control compensates for the voltage demand of the voltage regulator module, enabling the core electrical system to operate even in a derated operating mode. This coordinated control mechanism ensures that the vehicle maintains basic driving functions despite multiple fault conditions, completely avoiding the risk of high-speed stall and maximizing the drivable distance after a fault.

[0055] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
