[0025] In order to more clearly understand the purpose, technical solutions and advantages of the present application, the present application is described and illustrated below in conjunction with the accompanying drawings and embodiments.
[0026] like Figure 1As shown, the all-terrain vehicle 100 includes: a vehicle body 11, wheels 12, a seat 13, a shifting device 14, a power system 15 and a control module 16. The wheels 12 include a front wheel 121 and a rear wheel 122; the seat 13 is supported by the vehicle body 11, and the seat 13 includes at least a driver's seat; the shifting device 14 is disposed on the vehicle body 11; the power system 15 is supported by the vehicle body 11 and is used to provide power for the all-terrain vehicle 100, and at least one of the front wheel 121 and the rear wheel 122 is connected to the power system 15.
[0027] It should be noted that the power system 15 may include an engine, and the all-terrain vehicle is driven by fuel; the power system 15 may also include a power battery and a drive motor, and the all-terrain vehicle is driven by electricity; the power system 15 may also include an engine, a motor and a power battery, and the all-terrain vehicle is driven by a hybrid of oil and electricity, including series hybrid drive and parallel hybrid drive.
[0028] The control module 16 of the all-terrain vehicle 100 is connected to the power system 15. The control module 16 can control the power system 15 to execute different driving modes, including at least a first driving mode and a second driving mode. The driving mode can be a sports mode, an energy-saving mode, a standard mode, etc.
[0029] like Figure 2 As shown, the shift device 14 of the all-terrain vehicle 100 includes a shift interaction module 141, and the shift interaction module 141 can generate corresponding gear instructions based on the driver's operation. Taking the shift interaction module 141 as a button type as an example, each button represents a gear, such as P gear, R gear, N gear, D gear, etc., P gear is the parking gear, R gear is the reverse gear, N gear is the neutral gear, and D gear is the forward gear. When the driver presses a button, the shift interaction module 141 converts the driver's operation into a gear instruction. For example, when the driver presses the P gear button, the shift interaction module 141 can output the P gear instruction. The shift interaction module 141 can also be a knob type, a lever type, etc. The type of the shift interaction module 141 does not affect the implementation of this solution, as long as the shift interaction module 141 can issue the desired gear instruction according to the demand.
[0030] The shift device 14 of the all-terrain vehicle 100 also includes a shift execution component 142, which can execute the shift based on the gear command. When the driver makes a gear shifting action, such as pressing a button, turning a knob, or toggling a shift lever, the shift interaction module 141 outputs the corresponding gear command, and the shift interaction module 141 is connected to the control module 16. After receiving the gear command, the control module 16 determines whether the current state of the all-terrain vehicle 100 can shift gears. If it can shift gears, the gear command is sent to the shift execution component 142, such as a transmission. After receiving the gear command, the transmission executes the shift by changing the transmission ratio.
[0031] When the driver is in the driver's seat, after receiving the gear command, the control module 16 can also determine the driving mode corresponding to the gear command based on the gear command, and control the power system 15 to execute the corresponding driving mode. For example, when the driver makes a gear switching action, the gear shifting interaction module 141 outputs the corresponding gear command. After receiving the gear command, the control module 16 determines the corresponding driving mode in combination with the current operating state of the all-terrain vehicle 100 and the gear command, and controls the power system 15 to execute the corresponding driving mode. The control module 16 receives the gear command sent by the gear shifting interaction module 141, and determines the driving mode corresponding to the gear command in combination with the operating state of the all-terrain vehicle 100. The driver does not need to operate a driving mode switch such as a driving mode knob, a button, etc. to switch the driving mode of the all-terrain vehicle 100, which can save the driving mode switch and the hard wires connecting the driving mode switch and the control module 16, thereby reducing the hardware cost of the all-terrain vehicle 100 and making the wiring harness layout simpler.
[0032] It should be noted that the control module 16 can be a vehicle controller, which is the core controller of the all-terrain vehicle 100. It can interact with the accelerator pedal, transmission, instrument 17, battery, shift device 14, etc., and has a strong integration capability for the working status of each component of the all-terrain vehicle 100 and the running status of the all-terrain vehicle 100. The vehicle controller has a strong computing capability. The vehicle controller can be used to determine whether the gear command can be executed. For example, the all-terrain vehicle 100 cannot be engaged in the parking gear when driving at high speed. When the all-terrain vehicle 100 is driving in the forward gear, engaging the neutral gear is effective but engaging the reverse gear is invalid to prevent damage to the gearbox. The vehicle controller can also determine the driving mode corresponding to the gear command and control the power system 15 to execute the corresponding driving mode, which can improve the accuracy and safety of driving mode switching.
[0033] The forward gear of the all-terrain vehicle 100 includes at least a first forward gear and a second forward gear. When the gear position of the all-terrain vehicle 100 is the first forward gear, the control module 16 can control the power system 15 to execute the first driving mode. When the gear position of the all-terrain vehicle 100 is the second forward gear, the control module 16 can control the power system 15 to execute the second driving mode. During the driving of the all-terrain vehicle 100, the driver can switch between the first forward gear and the second forward gear to switch between different driving modes and obtain a richer driving experience.
[0034] Among them, the first driving mode can be a sports mode, and the second driving mode can be an energy-saving mode. At the same vehicle speed, when the all-terrain vehicle 100 is in the first driving mode, the output torque of the power system 15 is greater than the output torque of the power system 15 when the all-terrain vehicle 100 is in the second driving mode; or, at the same accelerator pedal voltage (stroke), when the all-terrain vehicle 100 is in the first driving mode, the output instantaneous torque of the power system 15 is greater than the output instantaneous torque of the power system 15 when the all-terrain vehicle 100 is in the second driving mode, and the same applies to the same accelerator handle opening. The all-terrain vehicle 100 can have stronger power and higher speed in the first driving mode, and the all-terrain vehicle 100 is more energy-saving and economical in the second driving mode, which can meet the driver's needs in different states and different environments of the all-terrain vehicle 100. For example, when the remaining fuel or power of the all-terrain vehicle 100 is low, switching to the second driving mode can extend the operating time of the all-terrain vehicle 100.
[0035] It should be noted that the control parameters corresponding to different driving modes can be adjusted according to needs. For example, the maximum speed of the all-terrain vehicle 100 in the second driving mode, i.e., the energy-saving mode, can be set to 50 km / h to limit the power output of the all-terrain vehicle 100 and save energy.
[0036] The driving mode of the all-terrain vehicle 100 also includes a third driving mode, which can be a standard mode. At the same vehicle speed, the output torque of the power system 15 of the all-terrain vehicle 100 in the standard mode is less than the output torque in the sports mode and greater than the output torque in the energy-saving mode; or, at the same accelerator pedal voltage (stroke), the output instantaneous torque of the power system 15 of the all-terrain vehicle 100 in the standard mode is less than the output instantaneous torque in the sports mode and greater than the output instantaneous torque in the energy-saving mode, and the same applies to the same accelerator handle opening. When the gear position of the all-terrain vehicle 100 is the reverse gear, the control module 16 controls the power system 15 to execute the third driving mode, i.e., the standard mode, to avoid the danger of reversing too fast to the driver while ensuring the power output of the all-terrain vehicle 100.
[0037] When the gear position of the all-terrain vehicle 100 is the parking gear or the neutral gear, the control module 16 controls the power system 15 to execute the third driving mode. If the all-terrain vehicle is in the sport mode when the gear position is in the parking gear or the neutral gear, when the driver switches the gear position to the forward gear, there may be a switching delay in the driving mode, resulting in the all-terrain vehicle starting in the sport mode state, the response speed is too fast, and there is a certain danger. The all-terrain vehicle in the third driving mode when the gear position is in the parking gear or the neutral gear can avoid this situation.
[0038] It should be noted that when the gears of the all-terrain vehicle 100 can be increased, the forward gear can also include a third forward gear. When the gear of the all-terrain vehicle 100 is the third forward gear, the control module 16 controls the power system 15 to execute the third driving mode such as the standard mode, so that the all-terrain vehicle 100 outputs moderate power and enriches the driver's driving experience.
[0039] See also Figure 3 Taking the button-type shift interaction module 141 as an example, the shift interaction module 141 includes a panel 1411, a plurality of buttons 1412 and a gear control unit 1413. The plurality of buttons 1412 are arranged on the panel 1411. Each button represents a gear, namely, P gear, R gear, N gear, DS gear and DE gear. P gear is a parking gear, R gear is a reverse gear, N gear is a neutral gear, DS gear is a first forward gear, and DE gear is a second forward gear. The gear control unit 1413 is connected to the button 1412 to receive a gear command. The gear control unit 1413 is also connected to the control module 16. The gear control unit 1413 sends a gear command to the control module 16. For example, when the driver presses the DS gear button, the gear control unit 1413 can receive the DS gear command and send the DS gear command to the control module 16. The control module 16 can determine that the driving mode is the first driving mode, i.e., the sports mode, according to the DS gear command, so as to control the power system 15 to output a larger power. The button-type shift interaction module 141 can differentiate the gear buttons so that the driver can distinguish them by feel, shape, etc., avoiding driver misoperation, making it safer and making the operation easier and simpler.
[0040] Specifically, the gear shift interaction module 141 also includes a plurality of gear position sensors 1414, such as Figure 4 As shown, the gear position sensors 1414 are respectively arranged in the buttons 1412, and can generate gear position instructions based on the driver's operation. For example, when the driver presses the DE gear button, the gear position sensor 1414 in the DE gear button generates a DE gear position instruction and sends the DE gear position instruction to the gear control unit 1413. Each button 1412 is provided with a gear position sensor 1414 and the gear position sensor 1414 is respectively connected to the gear control unit 1413, so that the generation and transmission of the gear position instruction signal can be more accurate. The button 1412 can also include a background light. When a button is pressed, the background light of the button will turn on to highlight it, reminding the driver that the button is selected, thereby preventing misoperation.
[0041] The gear shift interaction module 141 may also be a lever type, such as Figure 5As shown, the shift interaction module 141 includes a shift lever 1415, a shift slot 1416 and a panel 1417. The linear shift slot 1416 is set on the panel 1417. The shift slot 1416 can also be S-shaped or stepped. The shift interaction module 141 also includes a gear control unit 1413, which is used to receive the gear command input by the driver by operating the shift lever 1415, and send the gear command to the control module 16. The shift interaction module 141 can also be a knob type, and the driver can send the gear command by rotating the knob at a certain angle to the corresponding gear, which will not be elaborated in detail here.
[0042] The gear control unit 1413 and the control module 16 can communicate via a local area network, wherein the local area network communication includes CAN bus communication, LIN bus communication and the like. Taking CAN bus communication as an example, the CAN bus generally uses a twisted pair, the gear control unit 1413 is connected to the CAN bus, and after receiving the gear command, the gear command is sent to the CAN bus via a message, and the control module 16, such as the vehicle controller, reads the message from the CAN bus to receive the gear command. The gear control unit 1413 and the control module 16 communicate via the CAN bus, which can save two hard wires (a sending wire and a receiving wire), and the cost of adding a CAN node is lower than the hard wire cost, which can reduce the hardware cost of the all-terrain vehicle 100.
[0043] In addition, a hard line can be added on the basis of the LAN communication between the gear control unit 1413 and the control module 16, such as Figure 6 As shown, the hard wire connects the gear control unit 1413 and the control module 16. The gear control unit 1413 sends a pulse waveform signal such as a PWM wave signal through the hard wire to transmit the gear instruction to the control module 16. In the event that the CAN node of the gear control unit 1413 fails, the hard wire can ensure that the gear control unit 1413 can send the gear instruction to the control module 16.
[0044] like Figure 7 As shown, the all-terrain vehicle 100 also includes an instrument 17 , which is connected to the control module 16 . The control module 16 can send gear position instructions and driving mode instructions to the instrument 17 , and the instrument 17 can display the current gear position and driving mode of the all-terrain vehicle 100 .
[0045] It should be noted that the meter 17 and the control module 16 can be connected via a CAN bus. After receiving the gear command, the control module 16 determines whether the gear command can be executed, determines the corresponding driving mode, generates the corresponding driving mode command, and sends the gear command and the driving mode command to the meter 17. The meter 17 can display the gear and driving mode, so that the driver can understand the current operating status of the all-terrain vehicle 100. The driving mode can be displayed by an icon. When the driving mode changes, the icon switches, and the icon can also flash for a certain time, such as 10 seconds. The meter 17 can also emit a prompt sound to remind the driver.
