[0025] The embodiments of the present invention are described in detail below, and the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] In the relevant technical field, domain controllers can usually be defined according to the functions required by the vehicle. Due to the large configuration gradient span of each level of vehicle, the application flexibility of domain controllers is very low. Domain controllers cannot adapt well to the needs of high-end models, and when used in low-end models, resource utilization is low.

[0027] As the functions of automobiles continue to increase and become more and more complex, the number of ECUs (electronic control units) in automobiles has also increased rapidly. The architecture using a large number of ECU modules will lead to low computing efficiency, high data latency, and complex wiring harnesses. It is impossible to guarantee the rapid response ability of the automobile in the face of various emergencies, and the safety is not enough. The installation of domain controllers has become a development trend. The domain controller integrates multiple ECUs, and the vehicle can remove multiple controllers, making the whole vehicle lightweight and improving the efficiency of the whole vehicle. The centralized electronic and electrical architecture of the automobile domain refers to an architecture that divides the automobile into several functional blocks according to its functions, and each functional block is built with the domain controller as the main building. Multiple domain controllers are required to manage the whole vehicle system. For vehicles of different models, the configuration requirements of the vehicles are different, and the domain controllers required to manage the whole vehicle system are also different. For vehicles with high model levels, the configuration requirements of the vehicles are higher, the functions of the vehicles are more complex, and the number of domain controllers required to manage the whole vehicle system is also more. For vehicles with lower model levels, the configuration requirements of the vehicles are lower, the functions of the vehicles are simpler, and the number of domain controllers required to manage the whole vehicle system is also less.

[0028] Vehicle configuration can be divided into several gradients, and the domain control platform is defined by the vehicle configuration. After the development of the domain controller platform is completed, the resource allocation plan is fixed. The current vehicle configuration changes frequently, and this method is difficult to fully cover the vehicle requirements in the platform development stage. In the later application stage, there is often a mismatch between the vehicle electronic and electrical architecture plan and the functions required by the vehicle. Therefore, the domain controller platform needs to be constantly adjusted and replaced in accordance with the vehicle configuration requirements. The platform development workload is large and the cycle is long. The domain controller has low versatility and is difficult to meet the needs of today's vehicle models. In the development stage, the domain controller platform is usually upward compatible to meet the needs of the vehicle model. However, when the configuration gradient of the vehicle model is large, and when it is applied to low-end models, the resource utilization rate of the domain controller is low, resulting in a high cost per vehicle.

[0029] See also Figure 1An embodiment of the present invention provides a control device 1000, including a first controller 100 and a second controller 200, wherein the first controller 100 is configured to communicate signals with the vehicle to realize basic functions of the vehicle; the second controller 200 is configured to communicate signals with the vehicle to realize basic functions or extended functions of the vehicle, the basic functions of the vehicle are functions that every vehicle has, and the extended functions of the vehicle are different from the basic functions of the vehicle.

[0030] Specifically, the functions of a vehicle can be divided into basic functions and extended functions. Basic functions are common to all vehicles, and each vehicle model has basic functions. Vehicle functions other than basic functions are defined as extended functions, and the extended functions of vehicles are different for different vehicle models. For vehicles with lower vehicle models, the vehicle configuration requirements are lower and the vehicle extended functions are relatively few. For vehicles with higher vehicle models, the vehicle configuration requirements are high and the vehicle extended functions are relatively many.

[0031] Signals related to realizing basic functions of the vehicle can be defined as basic signals, and the basic domain controller can realize the basic functions of the vehicle by processing basic signals. For example, the throttle function of the vehicle is a function that every vehicle has, and the signals related to the throttle function of the vehicle can be defined as the basic signals of the vehicle, and the basic domain controller can realize the throttle function of the vehicle by processing the signals related to the throttle function of the vehicle. Signals related to realizing extended functions of the vehicle can be defined as extended signals, and the extended domain controller can realize the extended functions of the vehicle by processing extended signals. For example, some vehicles do not have a radio function, and some vehicles have a radio function. The radio function of the vehicle can be defined as an extended function of the vehicle, and the signals related to the radio function of the vehicle can be defined as the extended signals of the vehicle, and the extended domain controller realizes the radio function of the vehicle by processing the signals related to the radio function of the vehicle.

[0032] The first controller 100 may be a control unit or a domain controller of a plurality of control units. The first controller 100 may be a basic domain controller that can be used to process basic signals to implement basic functions of the vehicle. The first controller 100 may be applied to each vehicle to implement basic functions of the vehicle.

[0033] The second controller 200 can be a control unit or a domain controller of a plurality of control units. The second controller 200 can be a basic domain controller, which can be used to process basic signals to realize the basic functions of the vehicle. For some vehicles, the first controller 100 is not enough to meet the basic functional requirements of the vehicle. For example, when the body of the vehicle is relatively large, the connection port of the first controller 100 is limited and is not enough to realize all the basic functions of the vehicle. At this time, the second controller 200 can be additionally set, and the first controller 100 and the second controller 200 are used to process the basic signals to realize the basic functions of the vehicle. The second controller 200 can also be an extended domain controller, which can be used to process extended signals to realize the extended functions of the vehicle. After clarifying the requirements of the extended functions of the vehicle, the corresponding second controller 200 can be set according to the extended function requirements of the vehicle. For example, the vehicle needs to have the functions of air conditioning and electric seats, and the second controller 200 is set as a controller that can realize the functions of vehicle air conditioning and electric seats. The first controller 100 can be a controller set when the whole vehicle is first developed, which can solve the basic driving functions of the whole vehicle. In the subsequent development process, the functions of the vehicle can be adjusted by setting the second controller 200 according to the configuration requirements of the vehicle. The first controller 100 can be used every time the whole vehicle is developed, which provides convenience for the development of the whole vehicle.

[0034] In this way, the first controller 100 can be applied to each vehicle to realize the basic functions of the vehicle. After clarifying the functional requirements of the vehicle, the corresponding second controller 200 can be set according to the functional requirements of the vehicle, which can improve the flexibility of the control device 1000, make the final electronic and electrical architecture more suitable for the vehicle model, and improve the utilization rate of the controller resources.

[0035] Reference Figure 2 In some embodiments, the number of the first controller 100 is one, and the number of the second controller 200 is one or more.

[0036] Specifically, after clarifying the functional requirements of the vehicle, the corresponding second controller 200 can be set according to the functional requirements of the vehicle. The second controller 200 can be set with one. The second controller 200 can be a basic domain controller for processing basic signals, or an extended domain controller for processing extended signals. In the case where the second controller 200 is used to process basic signals, the control device 1000 includes two basic domain controllers, and both basic domain controllers are used to process the basic signals of the vehicle. In the case where the second controller 200 is used to process extended signals, the control device 1000 includes a basic domain controller and an extended domain controller, and the basic domain controllers are used to process the basic signals of the vehicle, and the extended domain controllers are used to process the extended signals of the vehicle.

[0037] The second controller 200 may also be set to multiple, and the multiple second controllers 200 may include a basic domain controller and an extended domain controller. The second controller 200 may be set to (n1+n2), and the (n1+n2) second controllers 200 may include n1 basic domain controllers and n2 extended domain controllers. The control device 1000 includes a total of (n1+1) basic domain controllers and n2 extended domain controllers.

[0038] The (n1+1) basic domain controllers are used to process the basic signals of the vehicle to realize the basic functions of the vehicle. For vehicles of different models, the configuration requirements for basic functions are different, and the value of n1 is also different. For example, for vehicles with larger bodies, to realize the basic functions of the vehicle, more basic domain controllers are needed to realize it, and the value of n1 can be set to be relatively large. If the first controller 100 can meet the configuration requirements of the basic functions of the vehicle, n1 can be set to zero, that is, the second controller 200 does not include a basic domain controller.

[0039] The n2 extended domain controllers are used to process the extended signals of the vehicle to realize the extended functions of the vehicle. For vehicles of different models, the configuration requirements for the extended functions are different, and the value of n2 is also different. For example, for vehicles with higher model levels, the configuration requirements of the vehicle are high, and the extended functions of the vehicle are relatively many. To realize the extended functions of the vehicle, it is necessary to use more extended domain controllers to realize them, and the value of n2 can be set to be relatively large. If the vehicle has no demand for extended functions, n2 can be set to zero, that is, the second controller 200 does not include an extended domain controller. In the case where the extended domain controller is set to multiple, the multiple extended domain controllers can be the same controller for realizing the same extended functions, and the multiple extended domain controllers can also be different controllers for realizing different extended functions. For example, in the case where multiple extended domain controllers are used to realize the air conditioning function of the vehicle, these multiple extended domain controllers can be the same controller. In the case where one extended domain controller is used to realize the radio function of the vehicle and another extended domain controller is used to realize the air conditioning function of the vehicle, the two extended domain controllers are different extended domain controllers.

[0040] In this way, the control device 1000 includes (n1+1) basic domain controllers and n2 extended domain controllers. After clarifying the configuration requirements of the vehicle, the values ​​of n1 and n2 can be set according to the configuration requirements of the vehicle (the values ​​of n1 and n2 can be set to zero). Such a control device 1000 is more flexible in vehicle application and can better cope with frequent configuration changes during the vehicle design stage to shorten the R&D cycle.

[0041] In some embodiments, the first controller 100 or the second controller 200 is configured to collect detection signals from sensors of the vehicle.

[0042] In certain embodiments, the first controller 100 or the second controller 200 is configured to drive an actuator of the vehicle to operate.

[0043] Specifically, refer to Figure 3 The signals of the whole vehicle can be divided into three categories. The first category is the detection signal given by the sensor to the controller, such as digital signal, analog signal, DSI (Digital input serializer) signal, etc. These signals can reflect the working status of the whole vehicle and the needs of users; the second category is the signal given by the controller to the actuator, such as bridge drive, high-side drive, low-side drive, PWM (pulse width modulation) drive, DSI drive, etc. The controller can drive the actuator to work by outputting these signals; the third category is the communication signal between controllers or vehicle modules, such as CAN network (Controller Area Network, bus interface), Lin (Local Interconnect Network, serial communication) network, Ethernet, etc.

[0044] In this way, both the basic domain controller and the extended domain controller collect detection signals from various sensors to determine the status of the vehicle and user needs, and drive various actuators to work to realize the corresponding basic functions and extended functions.

[0045] In some embodiments, the hardware interface of the first controller 100 is connected to the vehicle to enable signal communication between the first controller 100 and the vehicle, or the hardware interface of the second controller 200 is connected to the vehicle to enable signal communication between the second controller 200 and the vehicle.

[0046] Specifically, the first controller 100 and the second controller 200 are provided with corresponding hardware interfaces, which are connected to corresponding components on the vehicle through the hardware interfaces to control the vehicle to realize basic functions. For example, if the first controller 100 wants to realize the throttle function of the vehicle, the hardware interface corresponding to the first controller 100 can collect the detection signal of the sensor, determine the operation action performed by the user on the throttle according to the detection signal of the sensor, and after determining the operation action performed by the user on the throttle, control the throttle device of the vehicle to work, so as to realize the throttle function of the vehicle.

[0047] The controller can also be equipped with redundant hardware interfaces, which can be referred to Figure 4 , Figure 4The controller in the figure can be the first controller or the second controller. The controller needs to meet the requirements of vehicle configuration A, configuration B and configuration C. Some hardware interfaces a1, a2 and a3 of the controller are used to implement the function of configuration A, hardware interfaces b1, b2 and b3 are used to implement the function of configuration B, hardware interfaces c1, c2 and c3 are used to implement the function of configuration C, and hardware interfaces d1, d2 and d3 are reserved as hardware interfaces. When the vehicle needs new configuration requirements, the reserved hardware interfaces can be used to implement the new configuration requirements, which is more flexible in vehicle model application.

[0048] For the hardware interface of the controller, the same hardware interface can be used to implement multiple configuration requirements. For example, for multiple circuit modules of a vehicle, the power supply voltage can come from the same power supply voltage source, so that the connection end of a power supply voltage source can be used to power multiple circuit modules of the vehicle, thus realizing the reuse of a hardware interface. Multiple functions of the vehicle can be realized at the same time through the combination of multiple hardware interfaces. For details, please refer to Figure 5 , an extended domain controller can realize the configuration A, configuration B, configuration C and configuration D of the vehicle. Some hardware interfaces that realize the function of configuration A can also be used to realize the function of configuration D. For example, the controller can output a driving signal to drive device A through hardware interfaces a1-a3, and the controller can also output a driving signal to drive device D through hardware interfaces a1-a2. In this way, hardware interfaces a1-a2 can be used to output driving signals to drive devices A and D at the same time. In this way, by reasonably matching the hardware interfaces of the controller, the reuse of the hardware interfaces of the controller can be realized, thereby maximizing the use of the resources of the controller.

[0049] In some embodiments, the first controller 100 is a domain controller, or the second controller 200 is a domain controller.

[0050] Specifically, the first controller 100 or the second controller 200 can be set as a domain controller of the vehicle. The vehicle as a whole can be divided into multiple control areas according to the position, orientation relationship, etc., and a corresponding domain controller is set in each control area, and the hardware interface of the domain controller is connected to the corresponding control area.

[0051] In this way, the domain controller can realize local signal transmission within the corresponding control area, which is beneficial to saving costs such as the number of hardware and space layout, and is also beneficial to reducing the length of network cables and the complexity of network cable wiring.

[0052] In certain embodiments, the basic functions of the vehicle include functions related to the vehicle's throttle, brake system, or doors.

[0053] Specifically, each vehicle has the basic functions of the vehicle, which can be functions that can support the basic driving of the vehicle. The basic driving functions of the vehicle can be realized by the power domain, chassis domain and body domain of the vehicle. The power domain includes the throttle function of the vehicle, the chassis domain is composed of the transmission system, the driving system steering system and the braking system, and the rotation of the car is implemented through the cooperation of various systems. The body domain mainly includes functions related to door control.

[0054] In some embodiments, the extended functions of the vehicle include functions related to seats or air conditioning of the vehicle.

[0055] Specifically, some vehicles do not have extended functions. For vehicles with lower vehicle models, the configuration requirements are lower and the extended functions are fewer. For vehicles with higher vehicle models, the configuration requirements are higher and the extended functions are more. The extended functions of a vehicle can be non-driving functions of the car. The extended functions of a vehicle do not include basic driving functions. Vehicles without extended functions can also be used normally. For example, the electric adjustment function, heating function, ventilation function and radio function of the vehicle seat, even if the vehicle does not have these functions, the vehicle can still be used normally.

[0056] An embodiment of the present invention provides a control system, which includes a sensor, an actuator, and a control device 1000 according to any one of the above embodiments, and the control device 1000 is used to control the actuator according to a signal from the sensor.

[0057] Specifically, sensors, actuators and control device 1000 can be set according to the configuration requirements of the vehicle. The control device 1000 collects detection signals from various sensors to determine the state of the vehicle and user needs, and drives various actuators to work to realize corresponding vehicle functions.

[0058] An embodiment of the present invention provides a vehicle, the vehicle includes a control device 1000 of any one of the above embodiments or a control system of any one of the above embodiments, and the control device 1000 or the control system is arranged on a vehicle body.

[0059] Specifically, two types of controllers may be included in the vehicle, wherein the first controller 100 is used to implement the basic driving functions of the vehicle, such as the vehicle's throttle, braking system or door system are set in the first controller 100, and the second controller 200 is used to implement the vehicle's non-driving functions, such as the vehicle's air conditioning thermal management, cockpit entertainment system are set in the second controller 200.

[0060] The first controller 100 can be a controller set at the beginning of the vehicle development, which can solve the basic driving functions of the vehicle. In the subsequent development process, the vehicle functions are adjusted through the second controller 200 according to the vehicle configuration requirements. The first controller 100 can be used every time the vehicle is developed, which provides convenience for the vehicle development.

[0061] The second controller 200 is provided with a redundant hardware interface. If the redundant hardware interface on the second controller 200 can meet the new configuration requirements of the vehicle, the original control device 1000 architecture can be maintained, which can reduce the R&D cost and R&D cycle of the entire vehicle.

[0062] Reference Figure 6 The present invention provides a method for determining the electronic and electrical architecture of a vehicle, and the method for determining the electronic and electrical architecture of a vehicle includes: obtaining a model of a target vehicle, and determining basic functions and / or extended functions of the target vehicle according to the model of the target vehicle, wherein the basic functions of the vehicle are functions that each vehicle has, and the extended functions of the vehicle are different from the basic functions; determining the number and functions of second controllers according to the basic functions and / or extended functions of the target vehicle, wherein the second controllers are configured to implement the basic functions or extended functions of the vehicle; determining the electronic and electrical architecture of the target vehicle according to the number and functions of the first controller and the second controller, and the first controller is configured to implement the basic functions of the vehicle.

[0063] Specifically, this method is used to determine the type and quantity of controllers to build the corresponding electronic and electrical architecture, and the built electronic and electrical architecture is more in line with the model of the target vehicle. Different vehicle models have different basic functions and extended functions. The vehicle's requirements for basic functions and extended functions can be determined based on the vehicle model, and then the type and quantity of controllers can be determined.

[0064] Controllers can be divided into two categories: basic domain controllers and extended domain controllers. Basic domain controllers are used to implement basic functions of the vehicle, such as the vehicle's running function, and extended domain controllers can be used to implement extended functions of the vehicle, such as the vehicle's non-running function. The electronic and electrical architecture requires a total of (n1+1) basic domain controllers and n2 extended domain controllers. The first controller can be a basic domain controller, and the number is one. The number of the second controller is (n1+n2), including n1 basic domain controllers and n2 extended domain controllers. The values ​​of n1 and n2 can be determined based on the vehicle's requirements for basic functions and extended functions. The electronic and electrical architecture constructed in this way can be more in line with the vehicle model, improving the utilization rate of controller resources.

[0065] In certain embodiments, after determining the electronic and electrical architecture of the target vehicle, the method for determining the electronic and electrical architecture of the vehicle further includes: judging the feasibility of the electronic and electrical architecture of the target vehicle based on the number and function of the first controller and the second controller; if the electronic and electrical architecture of the target vehicle is not feasible, redetermining the number and function of the second controller to determine a new electronic and electrical architecture of the target vehicle.

[0066] Specifically, some systems in the car may have special requirements for hardware interfaces. For example, all hardware interfaces required by some systems must be in one controller. If the hardware interfaces of this vehicle system are connected to different controllers, the electronic and electrical architecture is not feasible. The hardware interfaces of some systems must be connected to different controllers respectively. If the hardware interfaces of this vehicle system are connected to the same controller, the electronic and electrical architecture is not feasible. The electronic and electrical architecture will also have corresponding requirements for the parameters in the circuit module. For example, the use of a certain controller will affect the current parameters or voltage parameters of the circuit module in the vehicle, thereby affecting the normal operation of the circuit module in the vehicle. In this case, the electronic and electrical architecture is not feasible. In the case that the electronic and electrical architecture of the vehicle is not feasible, a new electronic and electrical architecture is re-determined until the new electronic and electrical architecture is feasible.

[0067] In the control device 1000, control system, vehicle and electronic and electrical architecture determination method of the embodiment of the present invention, the control device 1000 includes a first controller 100 and a second controller 200. The first controller 100 is used to realize the basic functions of the vehicle. The basic functions of the vehicle are functions that every vehicle has, so the first controller 100 is a controller required by every vehicle. The second controller 200 is used to realize the basic functions or extended functions of the vehicle. The requirements of different vehicles for basic functions may be different. For vehicles with larger bodies, the first controller 100 is not enough to realize the basic functions of the vehicle. The corresponding second controller 200 can be set according to the basic function requirements of the vehicle. The requirements of different vehicles for extended functions may be different. After clarifying the functional requirements of the vehicle, the corresponding second controller 200 can be set according to the extended function requirements of the vehicle. The second controller 200 can be set according to the requirements of the basic functions or extended functions of the vehicle, which can improve the flexibility of the use of the control device 1000, make the final electronic and electrical architecture and the vehicle model more fit, and improve the utilization rate of the controller resources.
