Description

Technical Field

[0001] This invention belongs to the field of automotive coasting energy recovery driving binding technology, specifically relating to an automotive coasting energy recovery driving binding system, method, and electric vehicle. Background Technology

[0002] Vehicle energy consumption has become one of the most pressing issues for the industry. Currently, most automakers offer multiple levels of coasting energy recovery, and the braking process is combined with the deceleration generated by pressing the brake pedal. Many automakers now use brake-by-wire, resulting in several levels of coasting deceleration, braking feel, power mode, and steering. If these OEMs don't implement customized strategies and allow customers to choose for themselves, two main problems arise: First, the selection process is complex and information-intensive, making it inconvenient to use. Second, the selected mode is often not optimal; for example, combining strong coasting energy recovery with strong braking can cause a sudden increase in braking intensity, leading to extreme discomfort and complaints from passengers.

[0003] Given the technical problems existing in the above-mentioned vehicle coasting energy recovery driving, there are currently no relevant solutions; therefore, there is an urgent need to find effective solutions to address these issues. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a vehicle coasting energy recovery driving binding system, method, and electric vehicle, aiming to solve the problem of driving mode selection during existing vehicle coasting energy recovery.

[0005] This invention provides a vehicle coasting energy recovery driving binding system, the driving binding system including a vehicle coasting energy detection module, a pedal module and a vehicle driving module;

[0006] The vehicle coasting energy detection module is configured to classify energy recovery modes according to the deceleration of the vehicle coasting.

[0007] The pedal module is configured to divide the braking force according to the pedal travel into multiple pedal feel modes;

[0008] The vehicle driving module is configured to divide the vehicle into multiple driving modes based on its output power;

[0009] Each energy recovery mode configured in the car coasting energy detection module is pre-bound and matched with a pedal mode configured in the pedal module and a driving mode designed in the car driving module, thereby enabling the car to automatically bind the energy recovery mode, pedal feel mode and driving mode to form a driving binding mode during coasting driving.

[0010] Furthermore, the vehicle coasting energy detection module determines the coasting deceleration A based on the condition that A > 1.5 m / s². 2 At that time, it is classified as a high-level energy recovery mode;

[0011] The pedal module is classified into a low pedaling feel mode when the braking force F of the pedal travel meets the following condition: 35N≤F≤40N.

[0012] The vehicle driving module classifies the vehicle into energy-saving driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition that T > 9 seconds.

[0013] When the car is coasting, the high-level energy recovery mode, low pedal feel mode and energy-saving driving mode are automatically linked and matched to form the car's first driving binding mode, so as to keep the pedal feel consistent.

[0014] Furthermore, the vehicle coasting energy detection module assumes that the vehicle's coasting deceleration A satisfies: 0.8 ≤ A ≤ 1.5 m / s². 2 At that time, it was classified as a medium-level energy recovery mode;

[0015] The pedal module is classified into a high pedaling feel mode when the braking force F of the pedal travel meets the following condition: 25N≤F≤30N.

[0016] The vehicle driving module classifies the vehicle into a comfort driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition: 8s≤T≤9s.

[0017] When the car is coasting, the low-level energy recovery mode, high pedal feel mode and comfort driving mode are automatically linked and matched to form a second driving binding mode, so that the pedal feel of the car remains consistent.

[0018] Furthermore, the vehicle coasting energy detection module assumes that the vehicle's coasting deceleration A satisfies the condition: A < 0.8 m / s². 2 At that time, it is classified as a low-level energy recovery mode;

[0019] The pedal module is classified into a medium pedal feel mode when the braking force F of the pedal travel meets the condition: 30N < F < 35N.

[0020] The vehicle driving module classifies the vehicle into sport driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition that T < 8 seconds.

[0021] When the car is coasting, the low-level energy recovery mode, medium pedal feel mode and sport driving mode are automatically linked and matched to form a third driving binding mode, so as to keep the pedal feel consistent.

[0022] Furthermore, the braking force of the pedal travel is divided into pedal feel modes based on the deceleration of the pedal travel; the driving restraint system is used in electric vehicles, which are divided into multiple driving modes based on the output power of their drive motors.

[0023] Accordingly, in conjunction with the above solutions, the present invention also provides a method for vehicle coasting energy recovery driving binding, used in the driving binding system described above; the binding method includes the following process:

[0024] When the car coasting energy detection module detects the car's deceleration A, it should satisfy the condition: A > 1.5 m / s². 2 At that time, it is classified as a high-level energy recovery mode;

[0025] When the braking force F of the pedal travel is satisfied according to the pedal travel, the pedal module is classified as low pedaling mode.

[0026] When the vehicle's driving module determines the driving mode to be energy-saving based on the vehicle's 0-100 km / h acceleration time T, which satisfies T > 9 seconds;

[0027] When the car is coasting, the high-level energy recovery mode, low pedal feel mode and energy-saving driving mode are automatically linked and matched to form the car's first driving binding mode, so as to keep the pedal feel consistent.

[0028] Furthermore, the vehicle coasting energy recovery driving binding method provided by the present invention also includes the following process:

[0029] When the car coasting energy detection module detects the car's deceleration A, which satisfies the condition: 0.8 ≤ A ≤ 1.5 m / s² 2 At that time, it was classified as a medium-level energy recovery mode;

[0030] The pedal module is classified into a high pedaling feel mode when the braking force F of the pedal travel meets the following condition: 25N≤F≤30N.

[0031] The vehicle driving module classifies the vehicle into a comfort driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition: 8s≤T≤9s.

[0032] When the car is coasting, the low-level energy recovery mode, high pedal feel mode and comfort driving mode are automatically linked and matched to form a second driving binding mode, so that the pedal feel of the car remains consistent.

[0033] Furthermore, the vehicle coasting energy recovery driving binding method provided by the present invention also includes the following process:

[0034] The car coasting energy detection module assumes that the car's deceleration A during coasting meets the condition: A < 0.8 m / s². 2At that time, it is classified as a low-level energy recovery mode;

[0035] The pedal module is classified into a medium pedal feel mode when the braking force F of the pedal travel meets the condition: 30N < F < 35N.

[0036] The vehicle driving module classifies the vehicle into sport driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition that T < 8 seconds.

[0037] When the car is coasting, the low-level energy recovery mode, medium pedal feel mode and sport driving mode are automatically linked and matched to form a third driving binding mode, so as to keep the pedal feel consistent.

[0038] Accordingly, in conjunction with the above solutions, the present invention also provides an electric vehicle having a coasting energy recovery system; the electric vehicle includes the aforementioned vehicle coasting energy recovery driving restraint system.

[0039] Furthermore, the electric vehicle is also equipped with a vehicle controller, a DVD module, and a knob. The DVD module and the knob are electrically connected to the vehicle controller. The DVD module has a touch screen structure and can be used to select various driving binding modes of the vehicle. The knob can be rotated to select various driving binding modes of the vehicle.

[0040] The vehicle coasting energy recovery driving binding solution provided by this invention has a one-to-one correspondence between three levels of coasting energy recovery, driving modes ECO, Normal, and Sport, and low, medium, and high brake pedal feel. Drivers and passengers can switch synchronously by simply adjusting the driving mode button, and the braking process will not cause discomfort due to the change in coasting energy recovery level, which can effectively meet the experience of existing electric vehicles.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] like Figure 1 As shown, this invention provides a vehicle coasting energy recovery driving traction system, applicable only to vehicles with coasting energy recovery and vehicles where coasting energy recovery is superimposed; specifically, the driving traction system includes a vehicle coasting energy detection module, a pedal module, and a vehicle driving module; wherein,

[0051] The vehicle coasting energy detection module is configured to divide the energy recovery mode into multiple modes based on the deceleration of the vehicle coasting. That is, it is designed with multiple levels of energy recovery mode based on the deceleration of the vehicle during coasting. Each level of energy recovery mode is pre-designed and used directly in the vehicle coasting energy recovery system.

[0052] The pedal module is configured to divide the braking force according to the pedal travel into multiple pedal feel modes. That is, the car's pedals are designed to achieve multiple pedal feel modes based on the braking force and travel, thereby matching different levels of energy recovery modes.

[0053] The vehicle driving module is configured to divide the vehicle into multiple driving modes based on the vehicle's output power. That is, the vehicle itself is designed to implement multiple driving modes based on its power output power, thereby matching different road driving needs.

[0054] Based on the above three module designs, each energy recovery mode configured in the car coasting energy detection module is pre-bound and matched with a pedal mode configured in the pedal module and a driving mode designed in the car driving module. This allows the car to automatically bind the energy recovery mode, pedal feel mode, and driving mode to form a driving binding mode during coasting, eliminating the need for the driver to select the three modules separately. In other words, the energy recovery mode designed in the car coasting energy detection module, the pedal mode configured in the pedal module, and the driving mode designed in the car driving module are pre-designed and bound together, and can be directly used during coasting without the driver having to select the three modules separately, thus improving the driving experience.

[0055] The vehicle coasting energy recovery driving binding system provided by this invention can maximize the utilization of coasting energy recovery without affecting pedal feel, thereby reducing energy consumption and increasing vehicle mileage.

[0056] Preferably, in combination with the above schemes, such as Figure 1 As shown, the specific design is as follows: the car coasting energy detection module detects the car's coasting deceleration A based on the condition that A > 1.5 m / s². 2 At that time, it is classified as a high-level energy recovery mode;

[0057] The pedal module is classified into a low pedaling feel mode when the braking force F of the pedal travel meets the following condition: 35N≤F≤40N.

[0058] The vehicle driving module classifies the vehicle into energy-saving driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition that T > 9 seconds.

[0059] Specifically, during coasting driving, the high-level energy recovery mode, low pedal feel mode, and energy-saving driving mode are automatically linked and matched to form the car's first driving binding mode, thereby keeping the pedal feel consistent.

[0060] Preferably, in combination with the above schemes, such as Figure 1 As shown, the car coasting energy detection module determines the car's coasting deceleration A based on the following condition: 0.8 ≤ A ≤ 1.5 m / s². 2 At that time, it was classified as a medium-level energy recovery mode;

[0061] The pedal module is classified into a high pedaling feel mode when the braking force F of the pedal travel meets the following condition: 25N≤F≤30N.

[0062] The vehicle driving module classifies the vehicle into a comfort driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition: 8s≤T≤9s.

[0063] Specifically, during coasting driving, the low-level energy recovery mode, high pedal feel mode, and comfort driving mode are automatically linked and matched to form a second driving binding mode for the car, thereby keeping the pedal feel consistent.

[0064] Preferably, in combination with the above schemes, such as Figure 1 As shown, the car coasting energy detection module determines the car's coasting deceleration A based on the condition that A < 0.8 m / s². 2 At that time, it is classified as a low-level energy recovery mode;

[0065] The pedal module is classified into a medium pedal feel mode when the braking force F of the pedal travel meets the condition: 30N < F < 35N.

[0066] The vehicle driving module classifies the vehicle into sport driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition that T < 8 seconds.

[0067] Specifically, during coasting driving, the low-level energy recovery mode, medium pedal feel mode, and sport driving mode are automatically linked and matched to form a third driving binding mode for the car, thereby keeping the pedal feel consistent.

[0068] The above three driving binding modes are designed in a matrix combination and matching scheme as shown in Table 1 below. This ensures consistent pedal feel and eliminates the impact of coasting energy recovery on pedal feel. It also ensures the feasibility of each driving mode and provides a better experience for drivers and passengers.

[0069] Table 1

[0070]

[0071] Specifically, in conjunction with the above solutions, the driving mode of the car provided by this invention is as follows:

[0072] (1) Energy saving mode (ECO): Recover as much energy as possible, but also consider comfort. Therefore, the pedal feel should not be too aggressive and the braking intensity should be low.

[0073] (2) Comfort mode (Normal): The pedal force is small and the travel is short, but comfort must be ensured. Therefore, the comfort mode selects medium intensity recovery (initial braking response). In the middle and later stages, in order to meet the requirements of small force and short travel;

[0074] (3) Sport mode: powerful and long travel, select medium pedal feel and low coasting energy recovery. Sport mode is mainly for experiencing driving pleasure, without needing to consider energy saving. It is different from comfort mode and pursues driving differences.

[0075] Preferably, in combination with the above schemes, such as Figure 1 As shown, in this application, the braking force of the pedal travel is divided into pedal feel modes according to the deceleration of the pedal travel, specifically divided into: high, medium, and low; furthermore, the driving restraint system is used on electric vehicles, which are divided into multiple driving modes according to the output power of their drive motors, preferably the above-mentioned energy-saving mode, comfort mode, and sport mode.

[0076] Accordingly, in conjunction with the above schemes, such as Figures 1 to 2 As shown, the present invention also provides a method for vehicle coasting energy recovery driving binding, used in the driving binding system described above; the binding method includes the following process:

[0077] When the car coasting energy detection module detects the car's deceleration A, it should satisfy the condition: A > 1.5 m / s². 2 When the vehicle is coasting, it is classified as a high-level energy recovery mode; that is, the high-level energy recovery mode is designed based on the deceleration of the vehicle during coasting. The high-level energy recovery mode is designed in advance and used directly in the vehicle's coasting energy recovery system.

[0078] When the braking force F of the pedal travel meets the condition of 35N≤F≤40N, the pedal module is classified as a low pedal feel mode; that is, the car's pedal is designed to achieve a low pedal feel mode based on the braking force and travel of the pedal, which can be matched with a high-level energy recovery mode.

[0079] When the car's driving module determines the energy-saving driving mode based on the car's 0-100 km / h acceleration time T, which satisfies T > 9 seconds, the car itself is designed to achieve the energy-saving driving mode based on its power output, thereby matching the high-level energy recovery mode and the low pedal feel mode.

[0080] Based on the above three module designs, during coasting driving, the high-level energy recovery mode, low pedal feel mode, and energy-saving driving mode are automatically bound together and matched to form the first driving binding mode of the car, thereby ensuring a consistent pedal feel. In other words, the high-level energy recovery mode designed by the car coasting energy detection module, the low pedal feel mode configured by the pedal module, and the energy-saving driving mode designed by the car driving module are pre-designed and bound together. During coasting driving, they are directly bound together and used without the driver needing to select the three modules separately, thus improving the driving experience.

[0081] Preferably, in combination with the above schemes, such as Figure 1 As shown, the vehicle coasting energy recovery driving binding method also provided by the invention includes the following process:

[0082] When the car coasting energy detection module detects the car's deceleration A, which satisfies the condition: 0.8 ≤ A ≤ 1.5 m / s² 2 At that time, it is divided into medium-level energy recovery mode; that is, it is designed as low-level energy recovery mode according to the deceleration of the car during coasting. The low-level energy recovery mode is designed in advance and used directly in the vehicle coasting energy recovery system.

[0083] The pedal module is classified into a high pedal feel mode when the braking force F of the pedal travel meets the condition: 25N≤F≤30N. That is, the car's pedal is designed to achieve a high pedal feel mode based on the braking force and travel of the pedal. This allows it to be matched with a low-level energy recovery mode to achieve a combination of high and low pedal feel and ensure consistency in pedal feel.

[0084] The vehicle driving module classifies the vehicle into a comfort driving mode when the vehicle's 0-100 km / h acceleration time T satisfies the condition: 8s≤T≤9s; that is, the vehicle itself is designed to achieve a comfort driving mode based on its power output, thereby matching a low-level energy recovery mode and a high pedal feel mode.

[0085] When the car is coasting, the low-level energy recovery mode, high pedal feel mode and comfort driving mode are automatically linked and matched to form a second driving binding mode, so that the pedal feel of the car remains consistent.

[0086] Preferably, in combination with the above schemes, such as Figure 1 As shown, the vehicle coasting energy recovery driving binding method also provided by the invention includes the following process:

[0087] The car coasting energy detection module assumes that the car's deceleration A during coasting meets the condition: A < 0.8 m / s². 2 When the vehicle is coasting, it is classified as a low-level energy recovery mode; that is, the low-level energy recovery mode is designed based on the deceleration of the vehicle during coasting. The low-level energy recovery mode is designed in advance and used directly in the vehicle's coasting energy recovery system.

[0088] The pedal module is classified into a medium pedal feel mode when the braking force F of the pedal travel meets the condition: 30N < F < 35N. That is, the car's pedal is designed to achieve a medium pedal feel mode based on the braking force and travel of the pedal. This allows it to be matched with a low-level energy recovery mode to achieve a medium-low combination, and combined with the following sport driving modes to ensure the consistency of the pedal feel.

[0089] The vehicle driving module classifies the vehicle into sport driving mode when the 0-100 km / h acceleration time T satisfies the condition: T < 8s. That is, the vehicle itself is designed to achieve sport driving mode based on its power output, thereby matching a low-level energy recovery mode and a medium pedal feel mode to achieve a combination of sport driving mode and medium-low pedal feel, ensuring consistency in pedal feel.

[0090] When the car is coasting, the low-level energy recovery mode, medium pedal feel mode and sport driving mode are automatically linked and matched to form a third driving binding mode, so as to keep the pedal feel consistent.

[0091] Specifically, in conjunction with the above solutions, the present invention also provides a method for binding vehicle coasting energy recovery driving, which is only applicable to vehicles with coasting energy recovery and vehicles where coasting energy recovery is superimposed.

[0092] This invention also provides a method for binding vehicle coasting energy recovery driving, which does not involve mold opening and other costs, and has a relatively low implementation cost, as it can be achieved by simply adding a binding method; however, it requires two conditions: first, the vehicle has a coasting energy recovery superposition method, which makes the advantages of coasting energy recovery more obvious; second, the vehicle's brake pedal feel is adjustable, and several levels are needed to match the strategy.

[0093] Accordingly, in conjunction with the above schemes, such as Figures 1 to 2 As shown, the present invention also provides an electric vehicle having a coasting energy recovery system; the electric vehicle includes the aforementioned vehicle coasting energy recovery driving restraint system.

[0094] Preferably, in combination with the above schemes, such as Figure 1 As shown, the electric vehicle is also equipped with a vehicle controller, a DVD module, and a knob. The DVD module and the knob are electrically connected to the vehicle controller. The DVD module has a touch screen structure and can be used to select various driving binding modes of the vehicle. The knob can be rotated to select various driving binding modes of the vehicle. Figure 2 This is a schematic diagram based on the principle of the energy recovery strategy of this invention; Figure 2The system shown includes: Driving Mode 1; DVD operation interface 2; physical knob 3; Driving Mode Comfort 4; Driving Mode Eco 5; and Driving Mode Sport 6. Passengers can select a driving mode with a single button based on the current battery level or personal preference. Once the driving mode is selected, the coasting energy recovery mode and brake pedal feel mode will automatically match, requiring no further operation.

[0095] The vehicle coasting energy recovery driving binding solution provided by this invention has a one-to-one correspondence between three levels of coasting energy recovery, driving modes ECO, Normal, and Sport, and low, medium, and high brake pedal feel. Drivers and passengers can switch synchronously by simply adjusting the driving mode button, and the braking process will not cause discomfort due to the change in coasting energy recovery level, which can effectively meet the experience of existing electric vehicles.

[0096] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
