[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] As described in the background section, current automotive generators are designed and matched based on the maximum power consumption of the vehicle. Under normal use, they are in a state of excess power generation, resulting in energy waste and uneconomical fuel consumption for the vehicle.

[0024] Therefore, according to one aspect of the embodiments of this application, a control method for an automotive generator is provided, see below. Figure 1 As shown, the process of this method may include the following steps:

[0025] S10. Obtain the remaining battery power and vehicle operating parameters.

[0026] S20. Determine the current operating condition of the vehicle based on the vehicle operating condition parameters, wherein the operating condition characterizes the vehicle's power consumption status and / or the vehicle's driving environment.

[0027] S30. Control the generator's operating status based on the remaining power and / or the operating conditions.

[0028] In this embodiment, by real-time detection of the remaining battery power and the vehicle's operating conditions, a control strategy for the generator's operating status is comprehensively determined based on the current remaining battery power, the vehicle's power consumption, and the vehicle's driving environment. This ensures full utilization of the battery's power, avoids overcharging and over-discharging, improves the battery's lifespan and utilization rate, and reduces the vehicle's fuel consumption.

[0029] As an exemplary embodiment, controlling the generator's operating state based on the remaining power and / or the operating condition includes: controlling the generator to start working when the remaining power is less than a first preset value and / or the operating condition meets a first operating condition, wherein the first operating condition indicates that the vehicle's power consumption is greater than a first power consumption and / or the engine's required torque is less than a first torque.

[0030] In this embodiment, when the remaining battery power is detected to be less than a first preset value, continuing to control the battery to power the vehicle may result in over-discharge, reducing the battery's lifespan. Therefore, when the remaining battery power is detected to be less than the first preset value, the generator can be controlled to start working, supplying power to the vehicle while charging the battery. When the vehicle's current power consumption is determined to be greater than a first power consumption based on the vehicle's operating parameters, it indicates that the vehicle's power consumption is high. If the vehicle is powered solely by the remaining battery power, the consumption will be too rapid and may not meet the vehicle's power needs, thus affecting the vehicle's operation. Therefore, the generator can be controlled to start working at this time, allowing the battery and generator to supply power to the vehicle simultaneously. When the engine's current torque requirement is determined to be less than a first torque based on the vehicle's operating parameters, the vehicle may be on a downhill section or the brake pedal may be depressed. At this time, the generator can be controlled to start working to increase the vehicle's braking force. By detecting the remaining battery power and the vehicle's operating parameters, the vehicle's current usage needs are determined, improving the reliability of vehicle operation and enhancing the user experience.

[0031] It should be noted that the first preset value can be 10%-20% to avoid excessive battery discharge. The first power consumption and the first torque can be set experimentally according to the vehicle model, and are not intended to limit the embodiments of this application.

[0032] As an exemplary embodiment, the control method for an automotive generator further includes: controlling the generator to stop working when the remaining power is greater than a second preset value and / or the operating condition meets a second operating condition, wherein the second operating condition indicates that the vehicle's power consumption is less than a second power consumption and / or the engine's required torque is greater than a second torque.

[0033] In this embodiment, when the remaining battery charge is detected to be greater than a second preset value, continuing to control the generator to charge the battery would lead to overcharging, reducing battery life, increasing vehicle fuel consumption, and wasting energy. In this case, the generator can be stopped. When the vehicle's current power consumption is determined to be less than a second preset value based on vehicle operating parameters, indicating that the vehicle's power consumption is low, the generator can also be stopped, using the remaining battery charge to power the vehicle. The generator will start working again when the remaining battery charge is less than a first preset value. When the engine's current torque requirement is determined to be greater than a second preset value based on vehicle operating parameters, the vehicle may be on an uphill section or the accelerator pedal is being pressed. In this case, the generator can be stopped to increase the torque provided by the engine and meet the vehicle's current torque requirement. By detecting the remaining battery charge and vehicle operating parameters, the vehicle's current usage needs are determined, improving vehicle reliability, enhancing user experience, and reducing vehicle fuel consumption.

[0034] It should be noted that the second preset value can be 85%-95% to avoid overcharging of the battery. The second power consumption and the second torque can be set experimentally according to the vehicle model, and neither is intended to limit the embodiments of this application.

[0035] As an exemplary embodiment, when the vehicle is in cruise control mode, the control method further includes: when the remaining battery power is less than a third preset value, controlling the generator to start working, the third preset value being greater than the first preset value; when the remaining battery power is greater than a fourth preset value, controlling the generator to stop working, the fourth preset value being less than the second preset value.

[0036] In this embodiment, when the car is cruising, the vehicle speed is relatively constant, and the overall power consumption is also relatively stable. Therefore, the remaining battery charge can be controlled to remain between a third preset value and a fourth preset value, keeping the battery in its efficient operating range. When the remaining charge is less than the third preset value, the generator is controlled to operate; when the remaining charge is greater than the fourth preset value, the generator is controlled to stop operating, further improving energy utilization and reducing overall fuel consumption. The third preset value can be 45%-55%, and the fourth preset value can be 65%-75%. These settings can also be made differently depending on the vehicle model, engine model, and the vehicle's electrical equipment, and are not intended to limit the scope of this embodiment.

[0037] As an exemplary embodiment, the vehicle operating parameters include at least one of vehicle speed, engine speed, brake pedal signal, accelerator pedal signal, slope recognition signal, and vehicle electrical signals.

[0038] According to another aspect of the embodiments of this application, a control system for an automotive generator is provided, see [link to relevant documentation].Figure 2 As shown, the system includes a controller 10, which is used to execute the control method of the automobile generator as described in any one of claims 1-4, and further includes a battery 20, a control switch 30, and a generator 40; wherein the controller 10 is electrically connected to the battery 20 and the control switch 30 respectively; the control switch 30 is disposed between the battery 20 and the generator 40, and is used to receive the control signal from the controller 10 and change the on / off state based on the control signal.

[0039] In this embodiment, the controller 10 is electrically connected to the battery 20 and the control switch 30, respectively. It is used to receive information about the remaining power of the battery 20 and send control signals to the control switch. The controller controls the working state of the control switch 30 through the control signals, thereby controlling whether the generator 40 works. By real-time detection of the remaining power of the battery 20 and the operating conditions of the vehicle, the controller comprehensively determines the control strategy for the operating state of the generator 40 based on the current remaining power of the battery 20, the power consumption of the vehicle, and the driving environment of the vehicle. This ensures that the power in the battery 20 is fully utilized, avoids overcharging and over-discharging, improves the service life and effective utilization rate of the battery 20, and reduces the fuel consumption of the vehicle.

[0040] As an exemplary embodiment, the control system of the vehicle generator 40 also includes a key power switch connected in series between the control switch 30 and the battery 20.

[0041] In this embodiment, the control switch 30 may be a normally closed control switch, such as a normally closed relay or a normally closed transistor. When the key switch is closed during normal vehicle startup, the generator 40 starts to work. At the same time, the controller 10 starts to acquire the remaining power of the battery 20 and the vehicle operating parameters, and controls the conduction state of the control switch 30 based on the remaining power and the vehicle operating parameters, thereby controlling the working state of the generator 40 so that the vehicle can operate with high energy utilization and low fuel consumption.
