The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0026] In the description of the embodiments of this application, technical terms such as "first" and "second" are used solely to distinguish between different objects and should not be understood to indicate or imply relative importance, or to implicitly indicate the quantity, specific order, or primary and secondary relationship of the technical features indicated. In the description of the embodiments of this application, "multiple" means two or more (including two). Similarly, "multiple groups" means two or more (including two groups), and "multiple sheets" means two or more (including two sheets), unless otherwise specifically defined.

[0027] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0029] Motor energy recovery refers to the ability of the motor to convert some of the vehicle's kinetic energy into electrical energy while the vehicle is in motion and feed it back to the battery or other power-consuming devices. Currently, the motor's recovery capacity is limited by the battery's recovery capacity + accessory power consumption - reserved power. However, when the battery is fully charged, it has no recovery capacity. Inaccurate reporting of accessory power consumption at this time may result in the motor's recovered power not being fully utilized by the accessories, causing some to be diverted to the battery, resulting in overcharging.

[0030] In response to the above technical problems, an embodiment of the present application provides a vehicle motor energy recovery control method, which can change the motor's recovery capacity limit from an open loop to a closed loop, thereby adjusting the motor's recovery capacity in real time according to the battery overcharge situation, thereby preventing the motor from overcharging a fully charged battery when recovering energy.

[0031] like Figure 1 As shown in [A18], some embodiments of the present application provide a vehicle motor energy recovery control method, the vehicle motor energy recovery control method comprising: S101. While the vehicle is driving, if it is detected that the driver releases the accelerator or steps on the brake, obtain the actual charging power of the battery; S102, determining the current motor recovery capacity limit based on the actual battery charging power; S103 : Limiting the closed-loop control of the vehicle according to the current motor recovery capacity to execute a corresponding motor energy recovery operation to decelerate the vehicle. In some embodiments [A19], if it is detected that the driver steps on the accelerator, the motor drive torque is adjusted to accelerate the vehicle.

[0032] For example, when a driver presses the accelerator pedal, the method can capture this action through the accelerator pedal position sensor, convert it into an electrical signal, and transmit it to the vehicle's control unit (ECU). Upon receiving this signal, the ECU can perform a comprehensive analysis and calculation based on the current vehicle driving status (such as speed and gear position), as well as various other information such as the battery charge level and the motor's operating temperature. This calculation result enables the ECU to generate a precise command signal and transmit it to the motor controller. Upon receiving the command, the motor controller can rapidly adjust the on and off states of its internal power switching devices, thereby changing the voltage and current applied to the motor windings and their phase. Based on these changes, the motor adjusts its magnetic field strength and rotational speed, thereby varying the output drive torque, increasing the drive torque and ultimately accelerating the vehicle in accordance with the driver's intention to press the accelerator.

[0033] In some embodiments, if the driver is detected to be releasing the accelerator or applying the brakes, the motor is used to recover energy to achieve deceleration. To prevent overcharging of the battery when the motor is recovering energy, the method can change the motor's recovery capacity limit from an open loop to a closed loop, adjusting the motor's recovery capacity in real time based on the battery's overcharge condition. The corresponding calculation formula is as follows: The original maximum recovery power of the motor = the maximum recovery power of the battery + the power consumed by the accessories - the reserved power.

[0034] In the above embodiment [A20], the method can dynamically adjust the motor recovery capacity limit according to the actual charging power of the battery, avoid battery overcharging, optimize the energy recovery process, improve battery performance and service life, and ensure safe deceleration of the vehicle.

[0035] In some embodiments [A21], determining the current motor recovery capacity limit based on the actual battery charging power includes: Obtain the original maximum regenerative power of the motor and the allowable charging power of the battery; Calculate the current battery supercharge power based on the original maximum regenerative power of the motor and the actual charging power of the battery; When the current battery is overcharged according to the current battery supercharge power, the current motor recovery capacity limit is determined according to the current battery supercharge power, the actual charging power of the battery, the original maximum recovery power of the motor and the battery allowable charging power.

[0036] In the above embodiment [A22], the method can accurately evaluate the battery charging status. By combining the original maximum recovery power of the motor, the actual charging power of the battery and the allowable charging power of the battery, the current motor recovery capacity limit can be dynamically and reasonably determined, thereby effectively preventing battery overcharging, ensuring battery health and safety, and optimizing energy recovery efficiency.

[0037] In some embodiments [A23], the current motor recovery capacity limit is determined based on the current battery overcharge power, the actual battery charging power, the original maximum motor recovery power, and the battery allowable charging power, including: When the current battery overcharge power is greater than the first power threshold, the current motor recovery capacity limit is determined based on the original maximum motor recovery power, the actual battery charging power, the battery allowable charging power and the maximum power threshold; When the current battery overcharge power is not greater than the first power threshold and greater than the second power threshold, the current motor recovery capacity limit is determined based on the original maximum motor recovery power and the first power threshold; When the current battery overcharge power is less than the second power threshold, the current motor recovery capacity limit is determined based on the original maximum motor recovery power and the second power threshold; The maximum power threshold is greater than the first power threshold, and the first power threshold is greater than the second power threshold.

[0038] In some embodiments [A24], the first power threshold may be 5 kW; the maximum power threshold may be 8 kW; and the second power threshold may be 3 kW.

[0039] For example, when the battery overcharge exceeds 5 kW, the motor recovery capacity limit is adjusted to: the original maximum motor recovery power - max [actual battery charging power - battery allowed charging power, 8 kW]; When the battery overcharge is greater than 3kw and less than 5kw, the motor recovery capacity limit is adjusted to: the original maximum motor recovery power - 5kw; When the battery overcharge is less than 3kw, the motor recovery capacity limit is adjusted to: the original maximum motor recovery power - 3kw.

[0040] In the above embodiment [A25], the method can finely control the motor recovery capacity limit through a graded threshold strategy, dynamically adapt the recovery power according to different ranges of battery overcharging power, maximize the energy recovery efficiency while avoiding battery overcharging, and achieve a balanced optimization of safety and energy efficiency.

[0041] In some embodiments [A26], the method further comprises: When it is determined that the current battery is not overcharged based on the current battery overcharge power, the original motor recovery capacity limit is obtained; The original motor recovery capacity limit is adjusted upward according to the original maximum motor recovery power and a preset adjustment range to obtain the current motor recovery capacity limit.

[0042] For example, when the maximum battery recovery power minus the actual battery charging power is greater than a certain value and lasts for a certain period of time, it means that the battery is no longer overcharged. At this time, the motor recovery capacity can be slowly adjusted upward, adding 100w every 100ms, and must not exceed the original maximum motor recovery power.

[0043] In the above embodiment [A27], the method can fully tap the energy recovery potential by flexibly increasing the motor recovery capacity limit (within a preset safety range) when the battery is not overcharged, further improving the vehicle's endurance and energy efficiency while ensuring the stability of the system operation.

[0044] In some embodiments [A28], obtaining the original maximum recovered power of the motor includes: Obtain the maximum battery recovery power, accessory power consumption, and reserved power; Calculate the original maximum regenerative power of the motor based on the maximum regenerative power of the battery, the power consumed by the accessories, and the reserved power.

[0045] In the above embodiment [A29], the method can comprehensively consider battery performance, vehicle accessory energy consumption, and safety redundancy requirements, accurately calculate the original maximum recovery power of the motor, and provide benchmark parameters that are more in line with actual working conditions for energy recovery control, thereby improving system reliability and energy efficiency optimization effects.
