[0050] The following description of exemplary embodiments of the present application is made in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.
[0051] Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0052] It should be noted that the terminal devices involved in the embodiments of the present application may include but are not limited to mobile phones, personal digital assistants (PDAs), wireless handheld devices, tablet computers and other smart devices; display devices may include but are not limited to personal computers, televisions and other devices with display functions.
[0053] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.
[0054] Typically, when an electric vehicle's accelerator is released, the vehicle controller regenerates energy according to the regenerative braking level set by the driver. During this regenerative braking process, the vehicle decelerates. Currently, most electric vehicles display the current target regenerative braking level / gear on their instrument panel, or they may not display the target regenerative braking level / gear at all.
[0055] However, when the vehicle's maximum energy recovery capacity falls short of expectations, the vehicle fails to warn the driver. The driver is unaware of the motor or battery's limited state. When the driver activates high-speed regenerative braking, the vehicle's actual energy recovery capacity is insufficient, and the vehicle's deceleration falls far short of the driver's expectations. This misjudgment by the driver, coupled with the vehicle's failure to decelerate as expected, can lead to dangerous situations such as rear-ending the vehicle ahead or colliding with an obstacle.
[0056] Therefore, there is an urgent need for a vehicle energy recovery control method to realize the real-time energy recovery capability of the vehicle and ensure the safety and reliability of vehicle braking driving.
[0057] Please refer to Figure 1 , which shows a flow chart of a method for controlling vehicle energy recovery provided by an embodiment of the present application. The method for controlling vehicle energy recovery may specifically include:
[0058] Step 101: Acquire operation data of energy recovery gear adjustment of the vehicle.
[0059] Step 102: Determine a target energy recovery gear corresponding to the operation data, and a target energy recovery power corresponding to the target energy recovery gear.
[0060] Step 103: Obtain the current motor limit energy recovery power and the current battery limit energy recovery power of the vehicle.
[0061] Step 104 : Based on the motor limit energy recovery power and the battery limit energy recovery power, a preset screening strategy is used to determine the actual vehicle limit energy recovery power.
[0062] Step 105 : Compare the actual vehicle limit energy recovery power with the target energy recovery power to output actual vehicle energy recovery gear prompt information corresponding to the comparison result.
[0063] At this point, the driver can perform the corresponding braking operation based on the actual vehicle's energy recovery gear prompt information. For example, the driver can step on the brake pedal to make the vehicle achieve the desired deceleration capacity.
[0064] It should be noted that the operation data of the driver adjusting the energy recovery gear of the vehicle may be operation data obtained based on the driver's operation of the energy recovery lever. The operation data may include data of the driver adjusting the energy recovery lever to the desired energy recovery gear.
[0065] It should be noted that the operation data can be used to determine a target energy recovery gear, which can be an energy recovery gear desired by the driver.
[0066] For example, the driver adjusts the energy recovery lever to the second gear, and the second gear may be the target energy recovery gear, and the energy recovery power of the second gear may be the target energy recovery power.
[0067] It should be noted that the energy recovery power corresponding to each energy recovery gear may be pre-set based on the theoretical maximum energy recovery power of the vehicle's battery.
[0068] It can be understood that the current motor limit energy recovery power and the current battery limit energy recovery power may refer to the current motor limit energy recovery power and the current battery limit energy recovery power obtained after the target energy recovery gear is determined.
[0069] In this way, the actual vehicle's maximum energy recovery power can be determined based on the motor's maximum energy recovery power and the battery's maximum energy recovery power, and then the actual vehicle's maximum energy recovery power can be compared with the target energy recovery power to determine whether the current vehicle can actually achieve the driver's expected energy recovery capacity, so as to provide prompts to the driver based on the comparison results. This can avoid the situation where the vehicle rear-ends the vehicle in front or collides with an obstacle because the actual deceleration capacity fails to meet the deceleration capacity corresponding to the target energy recovery power, thereby ensuring the reliability and safety of electric vehicle braking.
[0070] Optionally, in a possible implementation of this embodiment, in step 103, the current first speed of the vehicle's motor, and the first negative torque and first efficiency value corresponding to the first speed can be obtained, and then based on the first speed, and the first negative torque and first efficiency value corresponding to the first speed, the current motor limit energy recovery power can be obtained using a preset first algorithm.
[0071] In this implementation, the current first speed of the motor may be the current motor speed, that is, the motor speed in the current detection cycle. The first negative torque corresponding to the first speed may be the minimum negative torque corresponding to the motor at the first speed. The first efficiency value corresponding to the first speed may be the efficiency corresponding to the minimum negative torque generated by the motor at the first speed.
[0072] Here, the first negative torque corresponding to the first speed may be obtained based on a signal sent by a motor controller.
[0073] In a specific implementation process of this implementation method, the current motor limit energy recovery power can be calculated based on the current motor speed, the minimum negative torque corresponding to the current motor speed, and the efficiency corresponding to the minimum negative torque when the current motor speed is emitted, using a preset first algorithm.
[0074] In this way, by utilizing the preset first algorithm, the current motor limit energy recovery power can be obtained more accurately and effectively according to the first speed, and the first negative torque and the first efficiency value corresponding to the first speed.
[0075] Optionally, in a possible implementation of this embodiment, in step 103, the current first current value and first voltage value of the vehicle's battery can be obtained, and then based on the first current value and the first voltage value, the current battery limit energy recovery power can be obtained using a preset second algorithm.
[0076] In this implementation, the current first current value of the battery may be the current minimum limit negative current, and the first voltage value may be the current operating voltage of the battery.
[0077] Here, the current first current value may be obtained based on a signal sent by the battery controller.
[0078] In a specific implementation process of this implementation, the current battery limit energy recovery power can be calculated based on the current minimum limit negative current and the operating voltage using a preset second algorithm.
[0079] In this way, a more accurate and effective battery limit energy recovery power can be obtained by utilizing the preset second algorithm according to the first current value and the first voltage value.
[0080] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementations to implement the vehicle energy recovery control method of this embodiment. For detailed descriptions, please refer to the relevant content in the aforementioned implementations and will not be repeated here.
[0081] Optionally, in a possible implementation of this embodiment, in step 104, the magnitude relationship between the motor's limit energy recovery power and the battery's limit energy recovery power can be specifically determined, and then based on a preset screening strategy and the magnitude relationship, the motor's limit energy recovery power and the battery's limit energy recovery power can be screened and processed, and based on the result of the screening process, the actual vehicle's limit energy recovery power can be determined.
[0082] In this implementation, the preset screening strategy may be to select the maximum value between the motor limit energy recovery power and the battery limit energy recovery power.
[0083] It is understandable that because the motor's maximum energy recovery power and the battery's maximum energy recovery power are both negative values, the maximum value of the two values can be used as the actual vehicle's maximum energy recovery power, that is, the minimum energy recovery capacity of the motor and battery systems can be used to characterize the actual energy recovery capacity of the entire vehicle.
[0084] In this way, the maximum value of the motor's limit energy recovery power and the battery's limit energy recovery power can be selected as the actual vehicle's limit energy recovery power based on the preset screening strategy and the relationship between the motor's limit energy recovery power and the battery's limit energy recovery power, thereby improving the accuracy of the limit energy recovery power.
[0085] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementations to implement the vehicle energy recovery control method of this embodiment. For detailed descriptions, please refer to the relevant content in the aforementioned implementations and will not be repeated here.
[0086] Optionally, in one possible implementation of this embodiment, the actual vehicle energy recovery gear position prompt information may include a prompt identifier and a prompt mode. In step 105, first, the actual vehicle's limit energy recovery power may be compared with the target energy recovery power. Second, in response to the actual vehicle's limit energy recovery power being less than the energy recovery power corresponding to the target energy recovery gear position, the prompt identifier of the actual vehicle energy recovery gear position prompt information is determined to be the target energy recovery gear position identifier, and the prompt mode is determined to be normal display. Third, the normally displayed target energy recovery gear position identifier is output.
[0087] In this implementation, the number of energy recovery gears is multiple. The prompt mark can be a gear mark. The prompt mode can include normal display, flashing display, etc.
[0088] In a specific implementation of this method, first, in response to the actual vehicle's maximum energy recovery power being greater than the target energy recovery power, a first energy recovery power for the first energy recovery gear is obtained, where the first energy recovery power is greater than the target energy recovery power. Second, in response to the actual vehicle's maximum energy recovery power being less than the first energy recovery power, a prompt indicator for the actual vehicle's energy recovery gear prompt information is determined to be the first energy recovery gear indicator, and a prompt mode is determined to be flashing. Third, the flashing first energy recovery gear indicator is output.
[0089] In this implementation, exemplarily, the number of the energy recovery gears may be three, and the energy recovery gears include a first gear, a second gear, and a third gear.
[0090] In another specific implementation of this method, when the target energy recovery gear is the third gear, first, the actual vehicle's limit energy recovery power can be compared with the energy recovery power corresponding to the third gear. Second, in response to the actual vehicle's limit energy recovery power being less than the energy recovery power corresponding to the third gear, the prompt indicator of the actual vehicle's energy recovery gear prompt information is determined to be the third gear indicator, and the prompt mode is set to normal display. Third, the normally displayed third gear indicator is output.
[0091] One scenario of the specific implementation process is that, when the target energy recovery gear is the third gear, in response to the actual vehicle's limit energy recovery power being greater than the energy recovery power corresponding to the third gear, the energy recovery power corresponding to the second gear is obtained, and the actual vehicle's limit energy recovery power is compared with the energy recovery power corresponding to the second gear; in response to the actual vehicle's limit energy recovery power being less than the energy recovery power corresponding to the second gear, the prompt identifier of the actual vehicle's energy recovery gear prompt information is determined to be the second gear identifier, and the prompt mode is flashing display, so as to output a flashing second gear identifier.
[0092] Another situation of this specific implementation process is that, when the target energy recovery gear is the third gear, in response to the actual vehicle's limit energy recovery power being greater than the energy recovery power corresponding to the second gear, the energy recovery power corresponding to the first gear is obtained, and the actual vehicle's limit energy recovery power is compared with the energy recovery power corresponding to the first gear. In response to the actual vehicle's limit energy recovery power being less than the energy recovery power corresponding to the first gear, the prompt identifier of the actual vehicle's energy recovery gear prompt information is determined to be the first gear identifier, and the prompt mode is flashing display, so as to output the flashing first gear identifier.
[0093] In another specific implementation of this method, when the target energy recovery gear is the second gear, first, the actual vehicle's limit energy recovery power can be compared with the energy recovery power corresponding to the second gear. Second, in response to the actual vehicle's limit energy recovery power being less than the energy recovery power corresponding to the second gear, the prompt indicator of the actual vehicle's energy recovery gear prompt information is determined to be the second gear indicator, and the prompt mode is set to normal display. Third, the normally displayed second gear indicator is output.
[0094] One case of this specific implementation process is that, when the target energy recovery gear is the third gear, in response to the actual vehicle's limit energy recovery power being greater than the energy recovery power corresponding to the second gear, it is determined whether the actual vehicle's limit energy recovery power is less than the energy recovery power corresponding to the first gear; if so, it is determined that the prompt mark of the actual vehicle's energy recovery gear prompt information is the first gear mark, and the prompt mode is a flashing display, so as to output a flashing first gear mark.
[0095] In another specific implementation process of this implementation method, voice prompt information of the actual vehicle energy recovery gear prompt information can also be output.
[0096] During the specific implementation process, the voice prompt information may include that the current energy recovery capability of the vehicle cannot reach the energy recovery capability of the target energy recovery gear.
[0097] It is understandable that when the actual vehicle's limit energy recovery power is greater than the target energy recovery power of the target energy recovery gear, a voice prompt may be output: "The current energy recovery capability of the vehicle cannot reach the energy recovery capability of the target energy recovery gear."
[0098] In this way, by comparing the actual vehicle's limit energy recovery power with the target energy recovery power of the target energy recovery gear and the energy recovery power of other gears, the corresponding prompt information can be accurately determined, further improving the safety and reliability of vehicle driving.
[0099] It should be noted that the specific implementation process provided in this implementation can be combined with the various specific implementation processes provided in the aforementioned implementations to implement the vehicle energy recovery control method of this embodiment. For detailed descriptions, please refer to the relevant content in the aforementioned implementations and will not be repeated here.
[0100] In order to better understand the method of the embodiment of the present application, the method of the embodiment of the present application is described below with reference to the accompanying drawings and specific application scenarios.
[0101] Figure 2 FIG. 1 is a flow chart of a method for controlling vehicle energy recovery provided by another embodiment of the present application. Figure 2 In this embodiment, the vehicle energy recovery control method can be applied to a vehicle controller, and the vehicle energy recovery control method may include:
[0102] Step 201: Acquire operation data of an energy recovery gear adjustment of a vehicle in response to a driver's operation of an energy recovery lever.
[0103] Step 202: Determine a target energy recovery gear and a target energy recovery power corresponding to the target energy recovery gear based on the operating data.
[0104] In this embodiment, the vehicle is equipped with an energy recovery lever, and the driver adjusts the energy recovery lever to control the energy recovery level, i.e., the energy recovery gear. The gear position to which the driver adjusts the energy recovery lever, i.e., the energy recovery gear, can be used as the target energy recovery gear.
[0105] In this embodiment, the operation data may include signal data for adjusting to the energy recovery gear position expected by the driver. Based on the operation data, the energy recovery gear position expected by the driver, ie, the target energy recovery gear position, may be obtained.
[0106] In this embodiment, the energy recovery power corresponding to the energy recovery gear may be pre-configured based on the theoretical maximum energy recovery power of the vehicle's battery.
[0107] Optionally, there may be multiple energy recovery gears.
[0108] For example, the energy recovery gears may include a first gear, a second gear, and a third gear, i.e., gear 1, gear 2, and gear 3. The energy recovery power of the energy recovery gears may be pre-configured based on the theoretical maximum energy recovery power of the battery. The energy recovery power of the three energy recovery gears may be calculated using the following formulas (1) to (3):
[0109]
[0110] P3=P Bat_Max +P offset (3)
[0111] Among them, P1 can be the energy recovery power corresponding to gear 1, P2 can be the energy recovery power corresponding to gear 2, P3 can be the energy recovery power corresponding to gear 3, and P Bat_Max The theoretical maximum energy recovery power of the battery, P Bat_Max is a negative constant, P offst Correction of power deviation, take positive value
[0112] Step 203: Obtain the current motor limit energy recovery power and battery limit energy recovery power.
[0113] In this embodiment, first, the current first speed of the vehicle's motor, as well as the first negative torque and first efficiency value corresponding to the first speed, can be obtained from the motor controller. Then, based on the first speed, the first negative torque and first efficiency value, a preset first algorithm can be used to obtain the current motor's maximum energy recovery power.
[0114] Here, the first speed may be the current speed of the motor, the first negative torque corresponding to the first speed may be the minimum negative torque corresponding to the motor at the current speed, and the first efficiency value corresponding to the first speed may be the efficiency corresponding to the minimum negative torque generated by the motor at the current speed.
[0115] Preferably, the motor limit energy recovery power can be used for the real limit recovery capability of the motor, and the preset first algorithm can be shown as the following formula (4):
[0116] P mot_Peak =T Peak N / (9549η1) (4)
[0117] Among them, P mot_Peak is the motor's maximum energy recovery power, N is the motor's current first speed, T Peak is the minimum negative torque corresponding to the motor at the current speed N, that is, the first negative torque, and η1 is the negative torque T generated when the motor works at the current speed N. Peak The efficiency corresponding to , that is, the first efficiency value.
[0118] In this embodiment, first, the current first current value and first voltage value of the vehicle battery can be obtained from the battery controller. Then, based on the first current value and the first voltage value, a preset second algorithm is used to obtain the current battery limit energy recovery power.
[0119] Here, the first current value may be the current minimum limit negative current of the battery, and the first voltage value may be the current operating voltage of the battery.
[0120] Preferably, the battery limit energy recovery power can be used for the real limit recovery capability of the battery, and the preset second algorithm can be shown as the following formula (5):
[0121] P Bat_Peak =A Peak U / (1000) (5)
[0122] Among them, P Bat_Peak is the battery's ultimate energy recovery power, A Peak is the current minimum limit negative current, that is, the first current value, and U is the current operating voltage, that is, the first voltage value.
[0123] It is understood that the vehicle's ultimate energy recovery capability can be characterized by its ultimate energy recovery power. The ultimate energy recovery power of an actual vehicle can be determined based on the ultimate energy recovery power of the motor and the ultimate energy recovery power of the battery.
[0124] Step 204 : Select a maximum value from the motor limit energy recovery power and the battery limit energy recovery power, and use the maximum value as the actual vehicle limit energy recovery power.
[0125] In this embodiment, the actual vehicle limit energy recovery power can be obtained by the screening strategy shown in formula (6):
[0126]
[0127] Among them, P Bat_Peak It can recover the maximum energy of the actual vehicle. It can be the motor's limit energy recovery power, P Bat_Peak Can recover power for battery limit energy.
[0128] It is understandable that because the motor's maximum energy recovery power and the battery's maximum energy recovery power are both negative values, the maximum value of the two values can be used as the actual vehicle's maximum energy recovery power, that is, the minimum energy recovery capacity of the motor and battery systems can be used to characterize the energy recovery capacity of the entire vehicle.
[0129] Step 205: Compare the actual vehicle's limit energy recovery power with the target energy recovery power.
[0130] Step 206 : When the comparison result shows that the actual vehicle limit energy recovery power is less than the target energy recovery power, the prompt mark of the actual vehicle energy recovery gear prompt information is determined to be the target energy recovery gear mark, and the prompt mode is normal display.
[0131] Step 207: Output the target energy recovery gear position identifier for normal display.
[0132] In this embodiment, if the actual vehicle's maximum energy recovery power is less than the target energy recovery power, this indicates that the vehicle's actual maximum energy recovery capability has reached the target energy recovery capability, i.e., the deceleration capability corresponding to the target energy recovery gear. This allows the target energy recovery gear indicator to be displayed normally on the instrument panel.
[0133] Step 208 : When the comparison result shows that the actual vehicle limit energy recovery power is greater than the target energy recovery power, obtain a first energy recovery power of the energy recovery gear that is greater than the target energy recovery power.
[0134] Step 209: Compare the actual vehicle's limit energy recovery power with the first energy recovery power. If the comparison result shows that the actual vehicle's limit energy recovery power is less than the first energy recovery power, determine that the prompt mark of the actual vehicle's energy recovery gear prompt information is the first energy recovery gear mark and the prompt mode is flashing display.
[0135] In this embodiment, when the actual vehicle limit energy recovery power is greater than the target energy recovery power and less than the first energy recovery power, the first energy recovery gear position identifier of the actual vehicle energy recovery gear position prompt information can be determined and the prompt mode is flashing.
[0136] In this embodiment, if the actual vehicle's maximum energy recovery power is greater than the target energy recovery power but less than the first energy recovery power, this indicates that the vehicle's actual maximum energy recovery capability cannot reach the target energy recovery capability, but can reach the capacity corresponding to the first energy recovery power, i.e., the deceleration capability corresponding to the first energy recovery gear. Thus, a flashing first energy recovery gear indicator can be displayed on the instrument panel to inform the driver that the vehicle's current deceleration capability is equivalent to the deceleration capability corresponding to the first energy recovery gear and cannot reach the deceleration capability corresponding to the target energy recovery gear.
[0137] Step 210: Output a flashing first energy recovery gear position indicator.
[0138] In this embodiment, a vehicle's energy recovery gear position prompt can be displayed on the vehicle's instrument panel. The prompt information includes a prompt indicator and a prompt mode. The prompt indicator can be a gear position indicator, i.e., a gear position number. The prompt mode can include a normal display and a flashing display.
[0139] In this embodiment, when the result of the comparison processing is that the actual vehicle's limit energy recovery power is greater than the first energy recovery power, a second energy recovery power of the energy recovery gear that is greater than the first energy recovery power can be obtained, and then the actual vehicle's limit energy recovery power and the second energy recovery power can be compared and processed to determine that the second energy recovery gear identifier of the actual vehicle's energy recovery gear prompt information and the prompt mode are flashing displays when the result of the comparison processing is that the actual vehicle's limit energy recovery power is less than the second energy recovery power.
[0140] It can be understood that the above comparison process can be repeated based on each energy recovery gear and the target energy recovery gear of the vehicle until the relationship between the energy recovery power of each energy recovery gear and the actual vehicle's limit energy recovery power is determined, so as to determine the energy recovery gear corresponding to the actual vehicle's energy recovery power and the actual vehicle's energy recovery gear prompt information.
[0141] In this embodiment, when the target energy recovery gear is determined, the prompt information output and displayed can be determined by comparing the relationship between the target energy recovery power and the actual vehicle's limit energy recovery power. If the actual vehicle's limit energy recovery power is less than the target energy recovery power, the prompt information displayed is determined to be the target energy recovery gear, and when the target energy recovery gear is displayed, the gear identification number is not flashing. If the actual vehicle's limit energy recovery power is greater than the target energy recovery power, the actual vehicle's limit energy recovery power is compared with the energy recovery power of other energy recovery gears that are greater than the target energy recovery power to determine the actual energy recovery gear, and the prompt information displayed is determined to be the actual energy recovery gear. When the actual energy recovery gear is displayed, the gear identification number is flashing.
[0142] It is understandable that, when the target energy recovery gear is determined, the prompt information to be output and displayed can also be determined by comparing the relationship between the actual vehicle's limit energy recovery power and the energy recovery power of each energy recovery gear.
[0143] In this embodiment, the energy recovery gears of the vehicle include gear 0, gear 1, gear 2, and gear 3. The energy recovery power of gear 1 is P1, the energy recovery power of gear 2 is P2, the energy recovery power of gear 3 is P3, and the actual vehicle limit energy recovery power is P Real_Peak , when the target energy recovery gear is determined to be gear 3, if P Real_Peak <P3, the gear position symbol of gear 3 is displayed, that is, the gear position symbol of the target energy recovery gear, and the gear position symbol does not flash.
[0144] If P3<P Real_Peak <P2, the gear position symbol of the 2nd gear is displayed and the gear position symbol flashes. The gear position symbol of the 2nd gear may be the actual energy recovery gear, indicating that the energy recovery capability corresponding to the current actual vehicle limit energy recovery power is actually equivalent to the energy recovery capability corresponding to the 2nd gear energy recovery power.
[0145] If P2<P Real_Peak <P1, the gear position symbol of gear 1 is displayed, and the gear position symbol flashes. The gear position symbol of gear 1 may be the actual energy recovery gear, indicating that the energy recovery capability corresponding to the current actual vehicle limit energy recovery power is actually equivalent to the energy recovery capability corresponding to the energy recovery power of gear 1.
[0146] If P Real_Peak >P1, the gear position symbol of gear 0 is displayed and the gear position symbol flashes.
[0147] Here, correspondingly, when the target energy recovery gear is a gear other than the 3rd gear, the prompt information to be displayed can also be determined in accordance with the above-mentioned comparison processing method.
[0148] It is understood that if the vehicle's current recuperation capacity can meet the deceleration expectations of the current target gear, the instrument panel displays the target gear for energy recuperation. If the vehicle's current recuperation capacity cannot meet the deceleration expectations of the current target gear, the instrument panel displays the actual gear corresponding to the energy recuperation capacity, and the gear indicator flashes. The vehicle may also issue an alarm to alert the driver. The alarm message may be "The vehicle's current energy recuperation capacity cannot meet the expected deceleration capacity." When the actual maximum recuperation capacity reaches the target recuperation capacity, the instrument panel displays the target gear, and the flashing and audible alarm stop.
[0149] In this embodiment, Figure 3 FIG. 1 is a schematic diagram showing the relationship between the energy recovery power and the limit energy recovery capability of multiple gears based on the SOC of the battery provided by another embodiment of the present application, such as Figure 3 As shown in the figure, the battery's state of charge (SOC) can affect the vehicle's ultimate energy recovery capability, which can be characterized by the ultimate energy recovery power. Figure 3 As shown, L1, L2, and L3 can represent the three gears respectively, and P1, P2, and P3 can represent the energy recovery power of the three gears respectively, that is, they represent the expected deceleration capabilities corresponding to the three gears, that is, the energy recovery capabilities corresponding to the three gears. The blue curve represents the limit energy recovery power P Real_Peak , which can represent the vehicle's ultimate deceleration capability. As the SOC value increases, the vehicle's ultimate deceleration capability becomes lower and lower, and it can only respond to the deceleration capability corresponding to the gear with greater energy recovery power. The higher the SOC value, the greater the ultimate energy recovery power P Real_Peak For each gear, when the limit energy recovery power is greater than the energy recovery power corresponding to the gear, the gear cannot perform the expected deceleration capability of the gear. Real_Peak When >P3, L3 expectation cannot be executed.
[0150] Furthermore, if the instrument panel detects that the actual regenerative power is less than the target regenerative power while displaying the actual regenerative gear, meaning that the actual regenerative capacity can meet the expected regenerative capacity of the current target regenerative gear, the actual vehicle regenerative gear indicator will be adjusted to the target regenerative gear indicator, with the indicator not flashing, and the instrument panel will display the target regenerative gear indicator, with the indicator not flashing. This situation often occurs when the vehicle's SOC decreases, the battery's regenerative capacity increases, and the regenerative capacity of the target gear is met.
[0151] In this embodiment, a recuperation level lever is installed inside the vehicle, with the recuperation gear displayed on the instrument panel. The system then determines the relationship between the vehicle's actual recuperation capacity and its target recuperation capacity. If the vehicle's current recuperation limit meets the deceleration target of the target gear, the instrument panel displays the target recuperation gear. If the vehicle's current recuperation capacity fails to meet the deceleration target of the target gear, the instrument panel displays the actual recuperation gear, which flashes and triggers a vehicle alarm. This allows the driver to take appropriate measures to avoid rear-ending the vehicle ahead or colliding with an obstacle, thereby ensuring reliable braking.

[0158] Optionally, in a possible implementation of this embodiment, the actual vehicle energy recovery gear prompt information includes a prompt identifier and a prompt mode, and the prompt output unit 405 is used to compare and process the actual vehicle limit energy recovery power with the target energy recovery power; in response to the actual vehicle limit energy recovery power being less than the energy recovery power corresponding to the target energy recovery gear, determining that the prompt identifier of the actual vehicle energy recovery gear prompt information is the target energy recovery gear identifier and the prompt mode is normal display; and outputting the normally displayed target energy recovery gear identifier.

[0160] In this embodiment, the first acquisition unit can acquire the operation data of the energy recovery gear adjustment of the vehicle, and then the first determination unit can determine the target energy recovery gear corresponding to the operation data and the target energy recovery power corresponding to the target energy recovery gear.

Since the actual vehicle limit energy recovery power can be determined based on the motor limit energy recovery power and the battery limit energy recovery power, and then the actual vehicle limit energy recovery power is compared with the target energy recovery power to determine whether the current vehicle can actually achieve the driver's expected energy recovery capacity, so as to prompt the driver based on the comparison result, it can avoid the vehicle rear-ending the vehicle in front or colliding with an obstacle due to braking deceleration not meeting expectations, thereby ensuring the reliability and safety of the electric vehicle.
