Abstract
Description
Technical Field
[0001] This application relates to vehicles, and more specifically, to an integrated controller and vehicle in the field of vehicles. Background Technology
[0002] In vehicle electrical systems, a single controller controls one actuator (which can be any of the following: power system, hydraulic system, steering system, lighting system, emergency stop device, etc.). This approach can lead to underutilization of the controller's available ports. For example, a hydraulic system controller might have 8 input ports and 8 output ports, but in practice, the control logic only requires 2 input ports and 1 output port. This leaves the remaining 6 input ports and 7 output ports unused, resulting in wasted resources. Utility Model Content
[0003] This application provides an integrated controller and vehicle. This application enables one controller to control multiple execution units simultaneously, reducing the number of controllers in the vehicle. This not only allows the effective ports of the controller to be fully utilized, but also simplifies the use of wiring harnesses, thereby saving resources.
[0004] In a first aspect, an integrated controller is provided for use in a vehicle, the vehicle including a brake pedal, a braking system, a hydraulic handle assembly, a hydraulic system, and a working device; the integrated controller includes: a first input interface, a second input interface, a first output interface, and a second output interface; the first input interface is electrically connected to the brake pedal, and the first output interface is electrically connected to the braking system; the second input interface is electrically connected to the hydraulic handle assembly, and the second output interface is electrically connected to the hydraulic system; the integrated controller is used to receive a stroke signal sent by the brake pedal through the first input interface, and to send the braking force corresponding to the stroke signal to the braking system through the first output interface, so that the braking system outputs the braking force to control the vehicle to decelerate; the integrated controller is also used to receive a mechanical signal sent by the hydraulic handle assembly through the second input interface, and to send a hydraulic control signal corresponding to the mechanical signal to the hydraulic system through the second output interface, so that the hydraulic system controls the working device to operate according to the hydraulic control signal.

[0020] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0021] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0022] In vehicle electrical systems, a single controller controls one actuator (which can be any of the following: power system, hydraulic system, steering system, lighting system, emergency stop device, etc.). This approach can lead to underutilization of the controller's available ports. For example, a hydraulic system controller might have 8 input ports and 8 output ports, but in practice, the control logic only requires 2 input ports and 1 output port. This leaves the remaining 6 input ports and 7 output ports unused, resulting in wasted resources.
[0023] Based on this, this application provides an integrated controller that integrates multiple control functions. Through different input and output interfaces, the control units corresponding to each function are connected to the integrated controller, thereby enabling one controller to simultaneously control multiple execution units. This reduces the number of controllers in the vehicle, not only making full use of the controller's effective ports but also simplifying the wiring harness usage, thus saving resources. Furthermore, because the integrated controller reduces the amount of wiring harness used, the wiring of the entire electrical system is simpler, which not only facilitates daily maintenance but also effectively reduces the difficulty of troubleshooting, improving the system's reliability and maintainability.
[0024] This application provides an integrated controller applied to a vehicle. The vehicle includes a brake pedal, a braking system, a hydraulic handle assembly, a hydraulic system, and a working device. The brake pedal is an operating component used by the driver to control the vehicle's deceleration or stopping. The braking system controls the vehicle's speed, causing it to decelerate or stop. The brake pedal triggers the braking system via a mechanical connection or electronic signal, causing the braking system to transmit braking force to the brakes on the wheels using hydraulic pressure or other methods, generating friction to slow wheel rotation until the vehicle stops. The hydraulic handle assembly is an input device operated by the driver. By converting the mechanical signals corresponding to the driver's mechanical actions into hydraulic signals, it controls the hydraulic system to drive the working device, such as extending or retracting the hydraulic cylinder to raise or lower the boom or adjust the angle of the bucket. When the working device is a bucket for loading tools, the vehicle is a loader; when the working device is a bucket for digging soil, rock, or other materials, the vehicle is an excavator.
[0025] like Figure 1 As shown, Figure 1 This illustration shows a schematic diagram of an integrated controller provided in an embodiment of this application; the integrated controller 100 includes: a first input interface 101, a second input interface 103, a first output interface 102, and a second output interface 104; as shown Figure 2 As shown, Figure 2This illustration shows a schematic diagram of the connection between the input / output interfaces of an integrated controller provided in this application and various vehicle components; the first input interface 101 is electrically connected to the brake pedal, and the first output interface 102 is electrically connected to the braking system; the second input interface 103 is electrically connected to the hydraulic handle assembly, and the second output interface 104 is electrically connected to the hydraulic system; the integrated controller 100 is used to receive the stroke signal sent by the brake pedal through the first input interface 101, and to send the braking force corresponding to the stroke signal to the braking system through the first output interface 102, so that the braking system outputs braking force to control the vehicle deceleration; the integrated controller 100 is also used to receive the mechanical signal sent by the hydraulic handle assembly through the second input interface 103, and to send the hydraulic control signal corresponding to the mechanical signal to the hydraulic system through the second output interface 104, so that the hydraulic system controls the working device to operate according to the hydraulic control signal.
[0026] In one exemplary embodiment, to reduce the number of controllers in the vehicle, fully utilize the effective ports of the controllers, and simplify the controller circuitry, a single controller manages both hydraulic control and braking control functions. The integrated controller 100 receives the brake pedal travel signal via its first input interface 101, determines the braking force corresponding to the travel signal, and sends the braking force to the braking system via its first output interface 102. The braking system, using hydraulic or other methods, transmits the braking force to the wheels, generating friction to slow wheel rotation until it stops. The integrated controller 100 determines the braking force corresponding to the travel signal using a conventional lookup table method. The integrated controller 100 pre-calculates and stores a series of relationships between brake pedal travel signals and corresponding braking force values. During operation, the integrated controller 100 searches the stored relationships between brake pedal travel signals and corresponding braking force values to find the braking force that matches the current brake pedal travel signal. This matching braking force is the braking force corresponding to the travel signal. The integrated controller 100 receives mechanical signals from the hydraulic handle assembly via its second input interface 103. The integrated controller 100 then determines the corresponding hydraulic control signal and sends it to the hydraulic system via its second output interface 104. The hydraulic system controls the working device's movement based on the hydraulic control signal, such as raising or lowering the working device. The mechanical signal refers to the physical action signal generated by the driver operating the hydraulic handle assembly, based on changes in its position, direction of movement, and amplitude. It reflects the specific position, direction of movement, and amplitude of the hydraulic handle assembly, thus conveying the driver's operating instructions. The integrated controller determines the hydraulic control signal based on the mechanical signal. It can pre-build the relationship between changes in the position, direction of movement, and amplitude of the hydraulic handle assembly and the control signal. After determining the changes in the position, direction of movement, and amplitude of the hydraulic handle assembly, it searches for the hydraulic signal corresponding to the current changes in the position, direction of movement, and amplitude of the hydraulic handle assembly within this relationship, thus obtaining the hydraulic control signal corresponding to the mechanical signal. Integrating the vehicle's hydraulic and braking control functions into a single controller not only reduces the amount of data and wiring harnesses in the controller, thus lowering the overall complexity of the vehicle's electrical system, but also reduces the number of connection points between the controller and the actuator, as well as between controllers themselves. This reduces potential sources of failure at these connection points, thereby improving the vehicle's operational stability.
[0027] For example, such as Figure 3 As shown, Figure 3This illustration shows a schematic diagram of another integrated controller provided in an embodiment of this application. The integrated controller 100 can be divided into different control units according to the integrated function type, such as a vehicle control unit a and a hydraulic control unit b. When the vehicle is in park, neutral, or drive gear, if the brake pedal inputs a travel signal to the integrated controller 100, the vehicle control unit a of the integrated controller 100 determines the braking force (e.g., zeroing the torsion of the drive motor in the power system) based on the travel signal and sends the braking force to the braking system. When the vehicle is in park, neutral, or drive gear, when the hydraulic handle assembly inputs a lifting signal (mechanical signal) to the integrated controller 100, the hydraulic control unit b of the integrated controller 100 outputs a hydraulic control signal (e.g., the speed and positive torque of the hydraulic motor) to the hydraulic system. The hydraulic system controls the lifting of the working device, wherein the hydraulic control signal determines the rotational speed of the hydraulic motor in the hydraulic system, thereby determining the lifting speed of the working device. When the hydraulic handle inputs a lowering signal (mechanical signal) to the integrated controller 100, the hydraulic control unit b outputs a hydraulic control signal (e.g., the speed and negative torque of the hydraulic motor) to control the hydraulic motor in the hydraulic system to reverse its movement, causing the vehicle's working device to lower.
[0028] In this embodiment, an integrated controller is provided with a first input interface 101, a second input interface 103, a first output interface 102, and a second output interface 104. The first input interface 101 is electrically connected to the brake pedal, and the first output interface 102 is electrically connected to the braking system. The integrated controller is used to receive the travel signal sent by the brake pedal through the first input interface 101, and to send the braking force corresponding to the travel signal to the braking system through the first output interface 102, so that the braking system outputs braking force to control the vehicle deceleration. The second input interface 103 is electrically connected to the hydraulic handle assembly, and the second output interface 104 is electrically connected to the hydraulic system. The integrated controller is also used to receive the mechanical signal sent by the hydraulic handle assembly through the second input interface 103, and to send the hydraulic control signal corresponding to the mechanical signal to the hydraulic system through the second output interface 104, so that the hydraulic system controls the working device to operate according to the hydraulic control signal. This system integrates multiple control functions into a single integrated controller. Through different input and output interfaces, the corresponding control units for each function are connected to the integrated controller, allowing one controller to simultaneously control multiple execution units. This reduces the number of controllers in the vehicle, fully utilizing the controller's available ports and simplifying wiring harness usage, thus saving resources. Furthermore, the reduced wiring harness size of the integrated controller simplifies the overall electrical system wiring, facilitating routine maintenance, reducing the difficulty of troubleshooting, and improving system reliability and maintainability.
[0029] In one possible implementation, the vehicle further includes a powertrain, a transmission system, a gear shifter, and an accelerator pedal; the integrated controller further includes: a third input interface 105, a fourth input interface 107, a third output interface 106, and a fourth output interface 108; the third input interface 105 is electrically connected to the gear shifter, the third output interface 106 is electrically connected to the transmission system; the fourth input interface 107 is electrically connected to the accelerator pedal, and the fourth output interface 108 is electrically connected to the powertrain; the integrated controller 100 is also used to receive a shift signal sent by the gear shifter through the third input interface 105, and send the target gear corresponding to the shift signal to the transmission system through the third output interface 106, so that the gearbox in the transmission system shifts the vehicle's current gear to the target gear; the integrated controller 100 is also used to receive a pedal opening signal sent by the accelerator pedal through the fourth input interface 107, and send the target driving force corresponding to the pedal opening signal to the powertrain through the fourth output interface 108, so that the powertrain outputs the target driving force to drive the vehicle.
[0030] To further reduce the number of controllers in the vehicle, eliminate communication delays between multiple controllers, and reduce synchronization errors in action response, power control and gear shift control functions are also integrated into the integrated controller. The target gear can be forward or reverse; see [link / reference]. Figure 1 and Figure 2 When the gear shifter (such as a gear shift lever) is switched to a forward gear, the integrated controller 100 receives the forward gear signal sent by the gear shifter through the third input interface 105, determines the target gear corresponding to the forward gear signal, and sends the target gear to the transmission in the transmission system, causing the transmission to switch the current gear to the target gear. The integrated controller 100 receives the pedal opening signal sent by the accelerator pedal through the fourth input interface 107, determines the target driving force corresponding to the pedal opening signal, and outputs the target driving force to the power system through the fourth output interface 108, thereby driving the vehicle forward through the target driving force. When the gear shifter (such as a gear shift lever) is switched to reverse gear, the integrated controller 100 receives the reverse gear signal sent by the gear shifter through the third input interface 105, determines the reverse gear corresponding to the reverse gear signal, and sends the reverse gear to the transmission in the transmission system, causing the transmission to switch the current gear to reverse gear. The integrated controller 100 receives the pedal opening signal sent by the accelerator pedal through the fourth input interface 107, determines the target driving force corresponding to the pedal opening signal, and outputs the target driving force to the power system through the fourth output interface 108, thereby driving the vehicle to reverse.
[0031] See Figure 3Since the shifting function is integrated into the integrated controller, a shifting control unit c can be defined within the integrated controller based on the shifting function. The shifting control unit c determines the target gear corresponding to the shifting signal and sends the target gear to the transmission system. The integrated controller 100 determines the target gear corresponding to the shifting signal using the existing lookup table method. In the integrated controller 100, a series of relationships between shifting signals of shifters and corresponding gears are pre-calculated and stored. When the integrated controller 100 is running, based on the current shifting signal of the shifter, the gear matching the shifting signal is searched in the stored relationship between shifting signals of shifters and corresponding gears. This gear is the target gear corresponding to the shifting signal.
[0032] In one possible implementation, the vehicle further includes a power battery, a charging detection circuit, and a battery management system; the integrated controller 100 also includes a fifth input interface 109 and a fifth output interface 1010; the fifth input interface 109 is electrically connected to the charging detection circuit, and the fifth output interface 1010 is electrically connected to the battery management system; the integrated controller 100 is also used to receive a charging request signal sent by the charging detection circuit through the fifth input interface 109, and when it is determined that the charging conditions of the power battery are met, to send a charging command to the battery management system through the fifth output interface 1010, so that the battery management system controls the power battery to charge.
[0033] See Figure 1 and Figure 2 When the charging detection circuit detects that the charging port of the vehicle is connected to the charging gun, it sends a charging request signal to the integrated controller 100 through the fifth input interface 109. After receiving the charging request signal, the integrated controller 100 communicates with the battery management system. The integrated controller 100 detects whether the high-voltage load of the vehicle is in a normal state. The high-voltage load of the vehicle includes the inverter, drive motor, hydraulic motor, charger, and related cooling system. The battery management system is responsible for monitoring and managing the status of the power battery, including parameters such as charge, temperature, and voltage. When the high-voltage load of the vehicle is in a normal state and the power battery is in a normal state, the integrated controller 100 sends a charging command to the battery management system through the fifth output interface 1010. The battery management system controls the power battery to charge. During the charging process, the battery management system continuously monitors the status of the power battery. Once the preset charging endpoint is reached (such as reaching the set state of charge percentage), the battery management system notifies the integrated controller 100. The integrated controller 100 sends a disconnect command to the battery management system to stop the charging process, ensuring that the circuit is safely disconnected and allowing the user to safely remove the charging gun.
[0034] One possible implementation is, such as Figure 4 As shown, Figure 4This illustration shows a schematic diagram of a working device provided in an embodiment of this application. Figure 4 The following explanation uses a loader as an example. The vehicle also includes a first position sensor A and a second position sensor B. The first position sensor A is located at the first end 3011 of the linkage mechanism 301 in the working device, and the second position sensor B is located at the second end 3012 of the linkage mechanism 301 in the working device. The first end 3011 is the end of the linkage mechanism 301 that is close to the wheel, and the second end 3012 is the other end of the linkage mechanism 301 that is away from the wheel.
[0035] The integrated controller 100 also includes a sixth input interface 1011 and a seventh input interface 1013;
[0036] The integrated controller 100 is also used to receive first position information sent by the first position sensor through the sixth input interface 1011, and send the first stop command corresponding to the first position information to the hydraulic system through the second output interface 104, so that the hydraulic system controls the working device to stop descending;
[0037] The integrated controller 100 is also used to receive second position information sent by the second position sensor through the seventh input interface 1013, and send the second stop command corresponding to the second position information to the hydraulic system through the second output interface 104, so that the hydraulic system controls the working device to stop rising.
[0038] A first position sensor A is provided on the end 3011 of the linkage mechanism 301 near the wheel in the working device, and a second position sensor B is provided on the end 3012 of the linkage mechanism 301 away from the wheel in the working device. (See also...) Figure 1 , Figure 2 and Figure 4The first position sensor A sends the detected position information to the integrated controller 100. The integrated controller 100 determines whether the position of the working device has reached the first predetermined position based on the received position information. If the first position sensor A is an optical encoder, the first position sensor A records the number of pulses output by the optical encoder as the initial position value when the working device descends to the lowest position. During the movement of the working device, the number of pulses output by the encoder is monitored in real time, and the number of pulses monitored in real time is compared with the number of pulses corresponding to the initial position value. If the difference between the number of pulses monitored in real time and the number of pulses corresponding to the initial position value is within a preset range, it indicates that the working device has descended to the lowest position, that is, the position of the working device has reached the first predetermined position. The integrated controller 100 sends the first stop command to the hydraulic system through the second output interface 104, so that the hydraulic system controls the working device to stay in the low-position flat position and will not continue to descend. The second position sensor B sends the detected position information to the integrated controller 100. The integrated controller 100 determines whether the working device has reached the second predetermined position based on the received position information. If the second position sensor B is also an optical encoder, it records the number of pulses output by the optical encoder as the initial position value when the working device rises to its highest position. During the movement of the working device, the number of pulses output by the encoder is monitored in real time, and compared with the number of pulses corresponding to the initial position value. If the difference between the real-time monitored pulse number and the number of pulses corresponding to the initial position value is within a preset range, it indicates that the working device has risen to its highest position, that is, the working device has reached the second predetermined position. The integrated controller 100 then sends a second stop command to the hydraulic system through the second output interface 104, causing the hydraulic system to control the working device to remain at the current lifting position, thus maintaining the lifting state. By monitoring position information with position sensors, issuing commands based on the position information with the integrated controller, and responding to the commands with the hydraulic system, precise operation control is achieved, which not only improves work efficiency but also enhances operational safety and stability.
[0039] In one possible implementation, the integrated controller 100 further includes a CAN network input interface 1015 and a CAN network output interface 1012;
[0040] The integrated controller 100 is also used to receive the operating status information of each component on the vehicle through the CAN network input interface 1015, and send the operating status information of each component to the remote server through the CAN network output interface 1012, so that the remote server can monitor the operating status of the vehicle.
[0041] See Figure 1The integrated controller 100 is equipped with a CAN network input interface 1015, which is used to receive the operating status information of various components on the vehicle (such as the power battery, air conditioner, gear shifter, transmission system, power system, etc.). The integrated controller 100 sends the received operating status information of various components on the vehicle to a remote server through the CAN network output interface 1012, so that the remote server can monitor the operating status of the vehicle based on the operating status information of each component.
[0042] In one possible implementation, the vehicle also includes a display screen;
[0043] The integrated controller 100 also includes a sixth output interface 1014;
[0044] The display screen and the sixth output interface 1014 are electrically connected;
[0045] The integrated controller is also used to send the operating status information of each component to the display screen through the sixth output interface 1014, so that the display screen can display the operating status information of each component.
[0046] See Figure 1 and Figure 2 The integrated controller 100 is provided with a sixth output interface 1014; the integrated controller 100 sends the working status information of each component to the display screen through the sixth output interface 1014 so that the display screen can display the working status information of each component, making it convenient for the driver to view the working status information of each component.
[0047] In one possible implementation, the vehicle also includes air conditioning;
[0048] The integrated controller also includes an eighth input interface 1017 and a seventh output interface 1016;
[0049] The eighth input interface 1017 is electrically connected to the display screen, and the seventh output interface 1016 is electrically connected to the air conditioner;
[0050] The integrated controller is also used to receive temperature control signals sent from the display screen via the eighth input interface 1017, and to send the target temperature corresponding to the temperature control signal to the air conditioner via the seventh output interface 1016 so that the air conditioner operates at the target temperature.
[0051] See Figure 1 and Figure 2 The driver can set the temperature on the display screen. The display screen sends the temperature control information corresponding to the temperature to the integrated controller 100 through the eighth input interface 1017.

[0052] One possible implementation is, such as Figure 5 As shown, Figure 5 The diagram shows the connection between an integrated controller and a hydraulic system and a power system according to an embodiment of this application. The vehicle also includes a multi-function controller 200; the multi-function controller 200 includes a ninth input interface 201 and an eighth output interface 202.
[0053] The second output interface 104 is electrically connected to the ninth input interface 201; the eighth output interface 202 is electrically connected to the hydraulic system.

[0056] The integrated controller 100 is connected to the hydraulic system and power system through the multi-function controller 200, which makes the response speed between the integrated controller 100 and the hydraulic system and power system faster and can prevent damage to the integrated controller 100 when there are abnormal conditions in the hydraulic system and power system.
[0057] The integrated controller 100 is electrically connected to the ninth input interface 201 of the multi-function controller 200 via its second output interface 104, and the multi-function controller 200 is electrically connected to the hydraulic system via its eighth output interface 202. The integrated controller 100 is electrically connected to the tenth input interface 203 of the multi-function controller 200 via its fourth output interface 108, and the multi-function controller 200 is electrically connected to the power system via its ninth output interface 204. This accelerates the data transmission between the integrated controller 100 and the hydraulic and power systems. At the same time, by connecting the integrated controller 100 to the hydraulic and power systems via the multi-function controller 200, damage to the integrated controller 100 can be avoided when there are abnormal conditions in the hydraulic and power systems.
