Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] All-terrain control refers to a car or vehicle system that can automatically adjust the vehicle's traction, suspension system, driving performance and other parameters according to different terrain conditions to optimize the vehicle's performance and stability under various road conditions. This system can usually be applied to a variety of terrains, including but not limited to: highways, urban roads, rural roads, ski resorts, deserts, muddy land, rocky roads, rugged mountain roads, water, and ice and snow roads. The all-terrain control system is designed to provide the vehicle with optimal performance and safety under various terrain conditions.

[0044] As a vehicle controller, IBDU is often unable to meet the complex functional requirements of the all-terrain control system due to limited storage space when processing large amounts of data, algorithms and logic. To meet this challenge, some all-terrain control logic and functions can be separated from IBDU and delegated to ESC for execution. However, the joint control of all-terrain commands by IBDU and ESC may lead to control confusion, which in turn endangers the stability and reliability of the all-terrain control system.

The command receiving end is connected to the ZCU, and the ZCU is respectively connected to a plurality of actuators. Specifically, the command receiving end is responsible for obtaining terrain control instructions and sending these instructions to the ZCU. After receiving the instructions, the ZCU converts these terrain control instructions into a plurality of request signals and sends these request signals to the corresponding actuators. The actuator performs corresponding control actions according to the request signal received from the ZCU. The present application not only improves the stability and reliability of the system through centralized control and distribution, but also realizes the optimal utilization of resources, ensuring the optimal performance of vehicle performance under different terrain conditions.

[0049] The command receiving end is used to obtain a terrain control command and send the terrain control command to the ZCU;

[0050] The ZCU is used to convert the terrain control command into a plurality of request signals and send the request signals to corresponding actuators;

[0053] In a possible implementation, the actuator includes:

[0054] Electronic Power Steering System (EPS), Electronic Differential Lock (EDL), suspension, breakable anti-roll bar and electric rear wing.

[0055] Specifically:

[0056] EPS: EPS is a modern steering system that uses an electronic control unit and an electric booster to help the driver provide additional assistance when steering. This system can adjust the steering assist according to parameters such as vehicle speed and steering angle, making the vehicle more flexible at different speeds.

[0057] EPS function: adjusts the vehicle's steering assist based on the received steering assist control signal to improve the vehicle's handling performance under complex terrain conditions.

[0058] EPS function: By adjusting the size of the electric power assist, the driver's operating burden is reduced, and the driving experience and safety of the vehicle are improved. The EDL is used to adjust the locking condition of the vehicle differential based on the differential lock control signal to enhance the traction ability of the vehicle in complex terrain.

[0059] EDL: Electronic differential lock is a control device for vehicle differentials, which simulates or replaces traditional mechanical differential locks through electronic control systems. It can intelligently sense the speed difference between wheels and automatically adjust the working state of the differential to ensure that the vehicle has better traction and stability under complex road conditions.

[0060] EDL function: Adjusts the locking condition of the vehicle's differential based on the received differential lock control signal to improve the vehicle's traction and off-road capability.

[0061] Function of EDL: When the wheels on one side slip, the driving force is transferred to the wheel with grip by locking the differential, ensuring that the vehicle can smoothly pass through complex terrain.

[0062] Suspension: The suspension system is an important part of the vehicle chassis, used to support the vehicle body and reduce shock. The suspension system can adjust the height and posture of the vehicle body to adapt to different road conditions and driving requirements, providing a comfortable driving experience and superior handling.

[0063] Suspension function: Adjust the height and posture of the vehicle body based on the received suspension control signal to adapt to different road conditions.

[0064] Suspension function: By adjusting the height and stiffness of the suspension system, the vehicle's passability and comfort are improved, ensuring that the vehicle can smoothly travel on various complex terrains. The breakable lateral stabilizer bar is used to adjust the connection state of the lateral stabilizer bar based on the stabilizer bar control signal to improve the lateral stability of the vehicle. The lateral stabilizer bar is disconnected when necessary to reduce the body roll and improve the off-road performance of the vehicle.

[0065] Breakaway anti-roll bar: Breakaway anti-roll bar is a vehicle stability control device, usually installed in the vehicle suspension system. It adjusts the connection state according to the lateral movement of the vehicle, helps maintain the stability and grip of the vehicle when driving on a curve, and improves the lateral stability of the vehicle.

[0066] Disconnectable lateral stabilizer bar function: adjusts the connection status of the lateral stabilizer bar based on the received stabilizer bar control signal to reduce body roll and improve vehicle stability.

[0067] Function of the detachable anti-roll bar: Disconnect the anti-roll bar when necessary to reduce body roll and improve the vehicle's off-road capability and passability, especially when driving on rough roads.

[0068] Electric rear wing: The electric rear wing is an aerodynamic design installed at the rear of the vehicle, and its position and tilt angle are adjusted by an electric motor or hydraulic system. The electric rear wing can adjust its posture according to the vehicle speed and driving status, improve the aerodynamic effect of the vehicle, improve driving stability and reduce aerodynamic resistance.

[0069] Electric rear wing function: adjusts the posture of the vehicle's rear wing based on the received rear wing control signal, optimizes aerodynamic performance, and improves stability during high-speed driving.

[0070] Function of the electric rear wing: By adjusting the posture of the rear wing, the aerodynamic characteristics of the vehicle are improved, wind resistance is reduced, and stability at high speeds is improved, especially in high wind speeds or high speeds.

[0071] In a possible implementation, the request signal further includes: an engine control signal, a transmission control signal, a stability control signal, and a torque distribution signal.

[0072] In a possible implementation, the actuator further includes: an engine management system (EMS), a transmission controller (TCU), an ESC and a transfer case control unit (TCCU).

[0073] Specifically:

[0074] EMS: EMS is the core control unit of the vehicle, responsible for monitoring, controlling and optimizing the operation of the engine. EMS collects data about engine status, environmental conditions, etc. through sensors, and then adjusts parameters such as fuel supply and ignition timing based on these data to ensure that the engine runs efficiently and reliably and meets emission standards.

[0075] EMS function: adjusts the operating parameters of the vehicle engine based on the received engine control signals.

[0076] Function of EMS: By adjusting parameters such as engine speed, ignition timing, and fuel injection amount, it ensures the optimal performance of the engine under different working conditions and improves fuel efficiency and power output.

[0077] TCU: TCU is an important part of the vehicle's automatic transmission, used to monitor and control the gear shifting process. TCU detects information such as vehicle speed and throttle position through sensors, and adjusts hydraulic valves or actuators based on these data to achieve smooth gear shifting, improve driving comfort and fuel economy.

[0078] TCU function: Adjust the shifting logic and mode of the vehicle transmission based on the received transmission control signal.

[0079] Function of TCU: By adjusting the gearshift timing and method of the transmission, it optimizes the vehicle's power transmission under different terrain conditions and improves driving smoothness and power response speed.

[0080] ESC: ESC is a vehicle dynamic stability control system designed to help the driver maintain vehicle stability in emergency situations. ESC senses changes in the vehicle's lateral motion and, when it detects a risk of skidding or loss of control, it corrects the vehicle's posture through the braking system or reduces engine output to avoid loss of control and improve driving safety.

[0081] ESC function: Monitors vehicle stability based on the stability control signal received, and intervenes in the braking system and engine output to prevent the vehicle from skidding or losing control.

[0082] Function of ESC: By monitoring the vehicle's motion state in real time, when the vehicle is detected to be unstable, it quickly adjusts the braking system and engine output to prevent the vehicle from skidding or losing control, thereby improving driving safety.

[0083] TCCU: TCCU is a key component of the four-wheel drive system, used to control and adjust the torque distribution ratio between the front and rear wheels. TCCU can automatically adjust the torque distribution between the front and rear wheels according to road conditions and driving needs to provide better traction and stability, so that the vehicle can achieve better performance and handling performance in complex terrain.

[0084] TCCU function: Adjust the torque distribution ratio between the front and rear wheels in the vehicle's four-wheel drive system based on the received torque distribution signal.

[0085] Function of TCCU: By dynamically adjusting the torque distribution between the front and rear wheels, it ensures the vehicle's optimal traction and stability under different road conditions, especially when driving on wet or soft surfaces.

[0086] In a possible implementation manner, the request signal further includes: a lighting control signal.

[0087] In a possible implementation, the actuator further includes: an atmosphere light;

[0088] The atmosphere light is used to adjust the interior lighting and atmosphere effects of the vehicle based on the light control signal.

[0089] Specifically:

[0090] Ambient lighting refers to a type of lighting installed inside or outside a vehicle to create a specific atmosphere or environmental effect. This type of lighting is usually designed to provide soft light and can present different colors and brightness to enhance driving comfort or improve the visual appeal of the vehicle interior.

[0091] In cars, ambient lights are usually installed in seats, footwells and other places in the car, and can be controlled by switches or remote controls. Their functions are not limited to providing lighting, but can also adjust the color and brightness of the light according to needs, creating a warm, relaxing or unique atmosphere, increasing driving pleasure and riding comfort. Many modern cars are equipped with ambient light functions to bring drivers and passengers a more pleasant driving and riding experience.

[0092] Ambient lighting function: adjusts interior lighting and ambient effects based on received lighting control signals.

[0093] Ambient lighting function: By adjusting the color, brightness and mode of the ambient lighting in the car, the visual effect in the car is enhanced, and the driving experience and comfort are improved. In addition, by adjusting the ambient lighting according to different driving modes (for example, off-road mode, city mode, etc.), the driver's awareness of the vehicle status can be enhanced.

[0094] In a possible implementation, the actuator is further configured to send an execution completion signal to the ZCU after completing the execution of the corresponding control action.

[0095] In addition to executing the corresponding control actions, the actuator is also responsible for sending the execution completion signal to the ZCU after the execution is completed. This ensures that each actuator of the system reports the execution status to the ZCU after completing the specified task, so that the system as a whole can monitor and coordinate the work of each component in real time. Through the transmission of the execution completion signal, the ZCU can promptly know the execution status of the actuator, and then adjust the operating status of the entire system to meet the needs of the vehicle or equipment and ensure the stability and reliability of the system.

[0096] In a possible implementation, the system further includes an instrument display screen (Instrument Pack, IPK). The IPK is connected to the ZCU.

[0097] The ZCU is further configured to convert the execution completion signal into a feedback signal, and send the feedback signal to the IPK.

[0098] The IPK is used to display the current terrain status based on the feedback signal.

[0099] In this application, the ZCU is connected to the IPK as the main control unit, which receives the execution completion signal from the actuator and converts it into a feedback signal. The ZCU then transmits the feedback signal to the IPK, which in turn displays the current terrain status on the instrument display based on these feedback signals. This structure can provide real-time feedback of the operating status of the vehicle or equipment to the driver or operator, helping them to better understand the vehicle's current working conditions and terrain environment, thereby enhancing the driver's awareness and grasp of the driving situation.

[0100] In a possible implementation, the instruction receiving end includes:

[0101] Advanced Terrain System Switch (ATSSW), Front Entertainment Control Module (FICM) and voice module.

[0102] Specifically, the ATSSW is used to receive user manual selection commands and convert these manual selection commands into terrain control instructions. The user can manually select different terrain modes or settings through the all-terrain system switch ATSSW to adjust the vehicle's performance and performance under different terrain conditions.

[0103] FICM is used to receive user firmware interface selection commands and convert these firmware interface selection commands into terrain control instructions. FICM is part of the vehicle's central control system and is responsible for handling functions related to multimedia and infotainment.

[0104] The voice module is used to receive the user's voice selection commands and convert them into terrain control commands. The voice module allows the driver to control various functions of the vehicle, including terrain control commands, through voice commands, improving the convenience and safety of operation.

[0105] The existence of these command receiving components allows users to interact with the all-terrain system in different ways and select different terrain control modes or settings, thereby adjusting the vehicle's driving characteristics and performance as needed, providing a more flexible driving experience and better adaptability.

[0106] The embodiment of the present application provides an all-terrain control system, which mainly includes three main components: a command receiving end, a ZCU and multiple actuators. Specifically, the command receiving end serves as the input interface of the system, is responsible for obtaining terrain control instructions from the outside, and transmits these control instructions to the ZCU. The ZCU plays a key role in command and coordination. It not only receives the control instructions transmitted by the command receiving end, but also converts them into specific request signals, and distributes these signals to each corresponding actuator according to different control requirements. Each actuator is directly connected to the ZCU, and their task is to perform predetermined control actions according to the specific request signal received from the ZCU. The present application converts terrain control instructions into request signals through the ZCU and distributes them to the actuators to achieve centralized and decentralized coordinated control. At the same time, the ZCU processes complex logic to improve the stability and reliability of the all-terrain control system.

[0107] It should be noted that each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. Some or all of them can be selected according to actual needs to achieve the purpose of the embodiment scheme.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
