Description

Technical Field

[0001] This invention relates to the field of automotive drive technology, specifically to a continuously variable torque control drive system, method, device, and medium for electric vehicles based on hub power generation. Background Technology

[0002] Existing electric vehicle drive systems generally adopt a centralized mechanical transmission architecture with a drive motor and a reducer. The vehicle's drive, transmission, and braking are independent mechanical subsystems, lacking a unified energy regulation path between them.

[0003] Under this architecture, the energy recovery function is triggered by braking conditions and can only be briefly engaged when the driver presses the brake pedal or releases the accelerator pedal deeply. During the vehicle's start-up, acceleration, and constant speed cruising phases, the drive system continuously outputs mechanical power, but the wheel ends do not have the structural conditions to generate electricity synchronously, so this part of the kinetic energy cannot be converted into electrical energy recovery.

[0004] When a vehicle is traveling at a stable speed on urban roads, the drive motor continuously consumes the power battery's energy. Since there is neither a power generation structure nor an electromagnetic recovery path at the wheel end, the kinetic energy is output in one direction throughout the entire journey, and the battery charge continues to decrease without any replenishment, resulting in a systemic loss of driving range. Summary of the Invention

[0005] In view of the above-mentioned problems, the present invention provides a continuously variable torque control drive system, method, device and medium for electric vehicles based on hub power generation.

[0006] Therefore, the technical problem solved by the present invention is that during the starting, acceleration and constant speed cruising phases of a vehicle, the drive system continuously outputs mechanical power, but the wheel ends do not have the structural conditions for synchronous power generation, so this part of the kinetic energy cannot be converted into electrical energy for recovery.

The vehicle controller controls the current regulation unit according to the driving condition signal, and changes the electromagnetic damping torque between the generator stator and the generator rotor by adjusting the generator current. The power battery is electrically connected to the hub-type permanent magnet generator and is used to recover the electrical energy of the hub-type permanent magnet generator under all driving conditions.

[0010] As a preferred embodiment of the continuously variable torque control drive system for electric vehicles based on hub power generation described in this invention, the current control unit continuously adjusts the generated current using a PWM closed-loop method; the generated current is directly proportional to the electromagnetic damping torque.

[0011] As a preferred embodiment of the continuously variable torque control drive system for electric vehicles based on hub power generation according to the present invention, the vehicle controller performs graded adjustment of the generated current according to the driving condition signal, wherein the graded adjustment steps include: when the driving condition signal is a starting condition, maintaining the triggering of a first current; when the driving condition signal is a constant speed condition, maintaining the triggering of a second current; and when the driving condition signal is a deceleration braking condition, adjusting the generated current to its maximum value.

[0012] As a preferred embodiment of the continuously variable torque regulation drive system for electric vehicles based on hub power generation according to the present invention, wherein: the four wheel hubs are respectively equipped with the flat wire drive motor, the hub-type permanent magnet generator and the current regulation unit; the vehicle controller adjusts the power generation current according to the vehicle speed of each wheel hub.

[0013] As a preferred embodiment of the continuously variable torque regulation drive system for electric vehicles based on hub power generation according to the present invention, the steps of the vehicle controller controlling the current regulation unit include: preset a normal range; in response to detecting that the wheel slip rate exceeds the normal range, reducing the power generation current of the corresponding wheel; and in response to the recovery of the wheel slip rate, restoring the power generation current to the target value.

[0014] This invention provides a continuously variable torque control drive method for electric vehicles based on hub power generation.

[0015] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a continuously variable torque control drive method for electric vehicles based on hub power generation, comprising: a flat wire drive motor driving a generator rotor to rotate via a coaxial rigid connection; the generator stator rotating synchronously with the wheel hub; a continuous electromagnetic induction being formed between the generator rotor and the generator stator; a vehicle controller continuously adjusting the generator current according to driving condition signals; the change in the generator current generating electromagnetic damping torque under the action of continuous electromagnetic induction; the electromagnetic damping torque being transmitted to the wheel hub via the generator stator to form wheel-end output torque; the wheel-end output torque being continuously controlled by the continuous adjustment of the generator current; and the continuous generation of electricity during the transmission of wheel-end output torque, converting driving kinetic energy into electrical energy and recovering it to the power battery.

[0024] Figure 3 The flowchart illustrates a continuously variable torque control drive method for electric vehicles based on hub power generation, as provided in one embodiment of the present invention. Detailed Implementation

[0025] To make the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] Example 1, referring to Figure 1 This is one embodiment of the present invention, which provides a continuously variable torque control drive system for electric vehicles based on hub power generation, including a flat wire drive motor, a hub-type permanent magnet generator, a current control unit, a vehicle controller, and a power battery.

[0027] Each of the four wheel hubs is equipped with a flat wire drive motor, a hub-type permanent magnet generator, and a current regulation unit. Each wheel is independent of the others, and the vehicle controller coordinates the regulation of the power generation current of each wheel. The power battery is centrally located at the bottom of the vehicle body and is connected to the four current regulation units and four flat wire drive motors through high-voltage wiring harnesses.

[0028] In this embodiment, both the flat wire drive motor and the hub-type permanent magnet generator are axial flux adjustable motors.

[0029] Example 2, refer to Figure 2 As shown, this is one embodiment of the present invention. Based on the previous embodiment, a continuously variable torque control drive system for electric vehicles based on hub power generation is provided, including a flat wire drive motor.

[0030] The flat wire drive motor adopts a flat wire winding structure, and the stator winding cross section is a rectangular flat wire. The slot fill factor is improved compared with the round wire motor, and the output torque per unit volume is greater.

[0031] The flat wire drive motor is fixedly installed inside the vehicle body suspension structure. Its output shaft is rigidly connected to the generator rotor of the hub-type permanent magnet generator through a coupling. The two share the same axis of rotation and rotate synchronously. There are no intermediate gears or reduction mechanisms.

[0032] The power battery continuously supplies power to the flat wire drive motor, which outputs rotational power and directly drives the generator rotor to rotate via the coaxial rigid connection.

[0033] This embodiment also provides a hub-type permanent magnet generator. The hub-type permanent magnet generator includes a generator rotor and a generator stator, both of which adopt a flat wire winding structure. The generator stator and the wheel hub are integrally formed, and the generator stator coils are directly cast and fixed to the inner wall of the wheel hub. The generator stator rotates synchronously with the wheel hub, forming the sole load-bearing body of the wheel. All radial and axial loads on the wheel are borne by this integrated structure.

[0034] Reference Figure 2 As shown, the generator rotor has a built-in permanent magnet array, which is evenly arranged along the circumference of the rotor. The generator rotor is located inside the generator stator, and there is an annular air gap between the generator rotor and the generator stator. Energy is transferred between the generator rotor and the generator stator only through the magnetic field in the annular air gap, and there is no mechanical contact.

[0035] When the flat wire drive motor drives the generator rotor to rotate, the magnetic field generated by the permanent magnet array built into the generator rotor rotates with the generator rotor, cutting the generator stator coil. A continuous electromagnetic induction is formed between the generator rotor and the generator stator, and an induced electromotive force is generated in the generator stator coil, outputting the generator current.

[0036] At the same time, continuous electromagnetic induction generates electromagnetic damping torque between the generator stator and the generator rotor. The electromagnetic damping torque is transmitted from the generator rotor to the generator stator through the annular air gap magnetic field, which in turn drives the wheel hub, which is integrally formed with the generator stator, to rotate, thereby providing driving force for the vehicle.

[0037] Example 3 is an embodiment of the present invention, which provides a current regulation unit.

[0038] The current regulation unit is electrically connected to the hub-type permanent magnet generator and is arranged on the suspension structure near the corresponding wheel.

[0039] The current control unit uses a PWM closed-loop method to continuously regulate the generator current, and achieves continuous linear change of the generator current within the range of 0 to 100% by adjusting the PWM duty cycle.

[0040] The generating current is directly proportional to the electromagnetic damping torque. That is, when the generating current increases, the electromagnetic damping torque between the generator stator and the generator rotor increases synchronously, and the driving torque transmitted to the wheel hub increases accordingly. When the generated current decreases, the electromagnetic damping torque decreases synchronously, and the driving torque on the wheel hub decreases accordingly.

[0041] The current regulation unit rectifies the electrical energy output by the generator and then recharges it back to the power battery.

[0042] This embodiment also provides a vehicle controller.

[0043] The vehicle controller collects accelerator pedal opening signal, brake pedal signal, vehicle speed signal of each wheel, and slip ratio signal of each wheel as driving condition signals. Based on the driving condition signals, it sends instructions to the current control unit of each wheel to independently adjust the power generation current of each wheel.

[0044] The vehicle controller performs graded adjustment of the generator current based on the driving condition signal. The execution steps are as follows: When the vehicle speed signal detection value is zero or lower than the preset starting speed threshold, and the accelerator pedal opening signal increases positively from 0%, and the brake pedal signal is not triggered, it is judged as a starting condition.

[0045] When the driving condition signal is in the start-up condition, the vehicle controller detects that the accelerator pedal opening is increasing from 0%. It first controls the drive motor to establish a basic rotational speed for the hub generator rotor, and simultaneously controls the hub generator to gradually increase the generating current from zero current in a ramp-up manner. This allows the electromagnetic coupling traction force between the stator and rotor to increase smoothly, gradually overcoming the vehicle's static friction resistance and enabling a smooth start-up of the wheel hub. Through gradual current control, problems such as magnetic coupling lock-up, drive motor overload, start-up jitter, and stalling caused by instantaneous high current are avoided, achieving a smooth and stable magnetic coupling start-up. At the same time, the hub-type permanent magnet generator converts some of the kinetic energy during the start-up phase into electrical energy, which is then recovered into the power battery.

[0046] The accelerator pedal sensor opening continues to increase, the brake pedal sensor has no braking signal input, and the vehicle speed continues to rise. The vehicle controller determines that the current driving condition is a continuous acceleration condition.

[0047] When the driving condition signal is acceleration, the vehicle controller linearly and synchronously increases the generator current of the in-wheel generator based on the steady-state current at start-up, progressively increasing the magnetic field coupling strength between the stator and rotor, and continuously increasing the positive traction electromagnetic torque of the rotor on the stator of the wheel hub, so that the wheels obtain continuously increasing driving power and the vehicle can accelerate continuously. At the same time, the vehicle controller limits the maximum generator current threshold, prioritizes the output of driving power, and recovers and stores the remaining excess power as electrical energy, balancing acceleration performance and energy recovery efficiency.

[0048] If the vehicle speed signal detection value is higher than the preset starting vehicle speed threshold, and the absolute value of the vehicle speed change rate is lower than the preset vehicle speed change rate threshold, and the absolute value of the accelerator pedal opening signal change rate is lower than the preset pedal change rate threshold, and the brake pedal signal is not triggered, and the duration of the above state is not less than the preset stability determination time, the vehicle controller determines the current driving condition as a constant speed condition.

[0049] When the driving condition signal is constant speed, the vehicle controller detects that the accelerator pedal opening is stable and the vehicle speed is constant. Based on the current vehicle speed, driving resistance, and battery state of charge, it dynamically calculates and locks a constant medium-current generation, so that the electromagnetic coupling traction torque generated by the hub generator is dynamically balanced with the vehicle's wind resistance and rolling resistance, maintaining stable vehicle speed. Without affecting constant speed driving, the system continuously maintains a stable power generation state, continuously converting excess mechanical energy from driving into electrical energy for storage, achieving uninterrupted energy recovery during cruising.

[0050] When the accelerator pedal sensor opening is zero, the brake pedal sensor has no input signal, and the vehicle speed signal detection value is greater than zero, the vehicle controller determines that the vehicle has entered a coasting state.

[0051] When the driving condition signal is coasting, the vehicle controller quickly increases the generator current of the hub generator, which generates a high-intensity reverse electromagnetic damping torque between the stator and rotor. The magnetic damping drags the hub to achieve smooth deceleration, efficiently converting the vehicle's inertial kinetic energy into electrical energy and recovering it to the power battery, thus achieving electronically controlled deceleration and kinetic energy recovery without mechanical wear.

[0052] The brake pedal sensor outputs a braking signal corresponding to the pedal travel and pressure, while the accelerator pedal sensor remains at zero. The vehicle controller determines that the vehicle is in normal braking condition.

[0053] When the driving condition signal is a normal braking condition, the vehicle controller, based on the braking depth requirement, prioritizes increasing the generator current of the in-wheel generator to the maximum allowable safe value, and uses high-intensity electromagnetic damping torque to achieve electric braking deceleration, converting the braking kinetic energy into electrical energy to be recovered into the power battery; when the electromagnetic braking force is insufficient to meet the total braking demand, the system maintains the maximum generator current unchanged, and the remaining braking force is supplemented by the mechanical braking system, realizing the coordinated braking logic of electric braking priority and mechanical braking assistance.

[0054] When the ABS system detects that the wheels are about to lock up and sends an intervention signal to the vehicle controller, the vehicle controller determines that the vehicle is in emergency braking and ABS anti-lock braking mode.

[0055] When the driving condition signal is emergency braking and ABS operation, the vehicle controller immediately cuts off the hub generator power generation load circuit, quickly returns the power generation current to zero, completely decouples the electromagnetic damping effect between the stator and rotor, and all braking force is independently borne by the mechanical braking system, completely avoiding electromagnetic torque interference with the vehicle stability control logic, and ensuring the safety and reliability of emergency braking.

[0056] This embodiment also provides an anti-slip control.

[0057] When the vehicle controller detects that the slip rate of a certain wheel exceeds the normal range, the vehicle controller sends a current reduction command to the current regulation unit of the corresponding wheel to reduce the power generation current of the corresponding wheel. As a result, the electromagnetic damping torque of the corresponding wheel decreases, and the adhesion between the wheel and the ground is restored. After the slip ratio of the corresponding wheel returns to the normal range, the vehicle controller restores the power generation current of the corresponding wheel to the target value, which is determined by the current driving condition signal.

[0058] The power generation current of the four wheels can be adjusted independently without interfering with each other, and the vehicle controller can simultaneously perform anti-skid control on multiple wheels.

[0059] Example 4, as Figures 1-2 As shown, this is an embodiment of the present invention, which provides an operating condition for a continuously variable torque control drive system for electric vehicles based on hub power generation.

[0060] In this embodiment, we take starting a vehicle on a wet and slippery road surface as an example.

[0061] When the vehicle is stationary, the vehicle controller detects an increase in the accelerator pedal opening and sends a command to the current control unit of each of the four wheels to trigger the first current. The four flat wire drive motors synchronously drive the corresponding generator rotors to rotate, and the four wheel hubs start under the electromagnetic damping torque driven by the first current.

[0062] During the vehicle start-up process, the vehicle controller detects the slip ratio of the four wheels. When the slip ratio of the left front wheel exceeds the normal range, the vehicle controller immediately sends a current reduction command to the left front wheel current regulation unit to reduce the power generation current of the left front wheel. The electromagnetic damping torque of the left front wheel decreases, and the adhesion of the left front wheel is restored. The power generation current of the other three wheels remains unchanged at the first current, and continues to provide driving torque, so that the vehicle can start smoothly.

[0063] Once the slip ratio of the left front wheel returns to the normal range, the power generation current of the left front wheel returns to the target value corresponding to the first current, and the four wheels resume coordinated driving.

[0064] Throughout the start-up process, four hub-type permanent magnet generators continuously generate electricity, converting the kinetic energy of the start-up phase into electrical energy and recovering it into the power battery.

[0065] Example 5, refer to Figure 3 As shown, this is an embodiment of the present invention, which provides a continuously variable torque control drive method for electric vehicles based on hub power generation, including the following steps: The flat wire drive motor drives the generator rotor to rotate through a coaxial rigid connection, and the generator stator rotates synchronously with the wheel hub. A continuous electromagnetic induction is formed between the generator rotor and the generator stator. The vehicle controller continuously adjusts the generator current according to the driving condition signal, and the change in the generator current generates electromagnetic damping torque under the continuous electromagnetic induction. The electromagnetic damping torque is transmitted to the wheel hub through the generator stator to form the wheel end output torque, and the wheel end output torque is steplessly controlled by the continuous adjustment of the generator current. The wheel-end output torque transmission process continuously generates electricity, converting driving kinetic energy into electrical energy and recovering it into the power battery.

[0066] This embodiment also provides an electronic device applicable to a continuously variable torque control drive method for electric vehicles based on hub power generation, comprising: a memory and a processor; the memory is used to store computer-executable instructions, and the processor is used to execute the computer-executable instructions to realize a continuously variable torque control drive system for electric vehicles based on hub power generation as proposed in the above embodiment.
