[0033] In order to facilitate understanding of the technical solutions provided by the embodiments of the present application, a kind of automobile electric appliance system provided by the embodiments of the present application is described below in conjunction with the drawings.

[0034] Although the drawings show the exemplary embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein.

[0035] In the claims and specification of the present application and the drawings accompanying the specification, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0036] Compared with the prior art, the number of sensors and controllers is large and the distribution is relatively dispersed, which causes the cables and power supply lines of other high-power devices between the components to be bundled together and subject to electromagnetic interference, affecting the stability of the automobile control; in the embodiments of the present application, each sensor group includes at least one sensor, and since the signal acquisition device is located in the threshold area of the automobile, at least one sensor is also located in the threshold area of the automobile, that is, a plurality of sensors are concentrated in the threshold area of the automobile instead of being dispersedly distributed in a plurality of different areas of the automobile; in addition, for each signal processing device, the signals collected by the sensor group are processed by the signal processor, and the cables between the signal processor and the sensors are relatively concentrated, and the target signal obtained by the signal processor is sent to the controller group instead of directly sending the collected signals to the controller group by the dispersed plurality of sensors; in addition, the controller group composed of at least one controller is located in the area between the passenger cabin floor and the cabin carpet of the automobile instead of being dispersedly distributed in a plurality of positions of the automobile, thereby reducing the phenomenon of cables and high-power electric appliance power supply lines being bundled together, reducing the electromagnetic interference on the communication between components, and improving the stability of the automobile control.

[0037] Please refer to Figure 1 , Figure 1is a structural schematic diagram of an automobile electrical system provided by an embodiment of the present application. As shown in Figure 1 the automobile electrical system 100 in the embodiment of the present application includes a cable connector 101, a controller group 102 including at least one controller, and at least one signal acquisition device;

[0038] Figure 1 In the embodiment, the controller group 102 takes the controller 103 and the controller 104 as an example. In actual application, the controller group 102 includes at least one controller. The controller group 102 can also include one controller or more than two controllers.

[0039] Figure 1 In the embodiment, the at least one signal acquisition device takes the signal acquisition device 105 and the signal acquisition device 106 as an example. In actual application, the at least one signal acquisition device can also include one signal acquisition device or more than two signal acquisition devices.

[0040] The automobile electrical system includes three parts. The first part is the cable connector. The second part is the controller group, which includes at least one controller. The third part is the at least one signal acquisition device. It can be understood that the system can also include other parts in addition to the three parts, which are not limited by the embodiment of the present application.

[0041] In the embodiment of the present application, the at least one signal acquisition device is located in different threshold areas of the automobile respectively. Taking the signal acquisition device 105 located in the first threshold area and the signal acquisition device 106 located in the second threshold area as an example, in actual application, the signal acquisition device can also be in other ways in the threshold area of the automobile.

[0042] The number of signal acquisition devices can be more than one. The signal acquisition device is located in the threshold area of the automobile. In the case of more than one signal acquisition device, different signal acquisition devices are located in different threshold areas of the automobile. The different threshold areas of the automobile refer to the areas where different signal acquisition devices are located belong to different threshold areas.

[0043] Further, for example, in the case of four doors of the automobile and four signal acquisition devices, the four signal acquisition devices are respectively located in the threshold areas of the four doors of the automobile. It can be understood that the number of signal acquisition devices is specific, and how the signal acquisition devices are distributed in the threshold area is not limited by the embodiment of the present application.

[0044] In the embodiments of the present application, for each of the signal acquisition devices, a signal processor is included for processing signals collected by a sensor group including at least one sensor to obtain target signals, and the signal processor is configured to send the target signals to a corresponding controller in the controller group. Figure 1 In the embodiments of the present application, the signal acquisition device 105 includes a signal processor 107 and a sensor group 108, the signal acquisition device 106 includes a signal processor 109 and a sensor group 110,

[0045] Each of the signal acquisition devices refers to each of the at least one signal acquisition device. Each of the signal acquisition devices includes two parts: a first part is a signal processor; and a second part is a sensor group including at least one sensor. It can be understood that each of the signal acquisition devices can further include other parts in addition to the two parts, and the embodiments of the present application do not limit the same.

[0046] The sensor group includes at least one sensor, and the at least one sensor is configured to collect signals. The at least one sensor refers to that the number of sensors in the sensor group can be one or multiple. In the case of multiple sensors, the multiple sensors in the sensor group can be of the same type or different types, and the embodiments of the present application do not limit the same.

[0047] Compared with the prior art in which multiple sensors are distributed at different positions of the vehicle, the multiple sensors need longer cables for transmitting the collected data, and the multiple sensors are distributed at different positions of the vehicle, so that the above cables and power supply lines of other high-power devices are bundled, electromagnetic interference affects signal transmission, and signal attenuation is caused. In the embodiments of the present application, the positions of the sensors are relatively concentrated, and in each signal acquisition device, the signals collected by the sensors are sent to the controller group through the signal processor, so that the required cables are less, the bundling of the cables for signal transmission and other high-power charging lines is reduced, and the stability of the vehicle control is improved.

[0048] Compared with the prior art, in which the cables are usually distributed in different areas of the automobile and the cables of the connecting components are usually pulled for a long distance, resulting in high cost and weight, in the embodiment of the application, the sensors are distributed in a relatively concentrated manner, the signals collected by the sensors are processed by the corresponding signal processors and then transmitted to the controller group, and the controller group is also located in a relatively concentrated area, so that the length of the cables is shortened and the cost and weight of the cables are reduced. The signal processor is configured to process signals collected by the sensor group to obtain a target signal. The signal processed by the signal processor is derived from the sensor group, and the signal processor and the sensor group belong to the same signal acquisition device. The signal processor can perform processing such as summarizing, classifying, integrating, and calculating on the signals collected by the sensor group; the signal processor obtains the target signal after processing the signals collected by the sensor group, and the signal processor transmits the target signal to the corresponding controller in the controller group. The signal processor transmits the target signal to the corresponding controller in the controller group, rather than transmitting data from the sensor group, thereby reducing the cables required for transmitting data by at least one sensor in the sensor group.

[0049] The signal processor is configured to transmit the target signal to the corresponding controller in the controller group. The controller group includes at least one controller. Since the signal processor is part of the signal acquisition device, the corresponding relationship between the signal processor and the controller is the corresponding relationship between the signal acquisition device and the controller; this corresponding relationship can be preset in advance. The controller group includes at least one controller. When the controller group includes only one controller, the signal processor is configured to transmit the target signal to the controller.

[0050] The controller group includes at least one controller. Generally, the controllers in the automobile each have a respective control function. For the target signal, there are at least two cases: first, the target signal can include signals (or information corresponding to the signals) collected by all sensors in the sensor group; second, the target signal can include signals (or information corresponding to the signals) required by the controller corresponding to the current signal processor. For the first case, the signals collected by all sensors in the sensor group are transmitted to the controller group, and at least one controller in the controller group can selectively receive / utilize as needed to achieve the control function; for the second case, the sensor group selectively collects / transmits signals of at least one sensor, and at least one controller in the controller group can achieve the control function according to the target signal.

[0051] In the embodiment of the present application, the controller group is located in the area between the passenger cabin floor and the cabin carpet of the automobile, and is connected with the automobile wiring harness outside the system through the cable connector; wherein at least one controller in the controller group is used to control the automobile according to the received target signal.

[0052] The controller group is located in the area between the passenger cabin floor and the cabin carpet of the automobile, and the role is to reasonably utilize the space of the automobile, so that the controller group is more concentratedly distributed. Since the components contained in the system mainly include sensors, signal processors and controllers, in order to realize the control effect of the controller, the control instruction of the controller can be executed by other components of the automobile, and therefore the controller is connected with the automobile wiring harness outside the system through the cable connector, so as to realize the control of the controller on the automobile.

[0053] Further, the system meets the automobile electrical appliance topology structure contained in the electrical appliance system of the embodiment of the present application, and can also include other components according to actual needs, and the types and quantities of the components do not affect the implementation of the embodiment of the present application.

[0054] Further, in the embodiment of the present application, the at least one signal acquisition device is respectively located in different door sill areas of the automobile, which can include: for each signal acquisition device, the at least one sensor in the sensor group is close to the metal plate on the vehicle outer side of the door sill; wherein the metal plate on the vehicle outer side of the door sill has a hole corresponding to the position, and the hole is filled with a non-metal material.

[0055] The signal collected by the sensor for vehicle control is usually generated by the object / environment outside / surrounding the automobile; in order to reduce the influence of the automobile itself on signal acquisition, such as the structure of the automobile body or the material of the automobile body, etc., the signal shielding or shielding in the signal acquisition process, in the embodiment of the present application, the sensor can be close to the metal plate on the vehicle outer side of the door.

[0056] Due to the metal characteristics of the metal plate, the signal will be shielded to a certain extent, in order to reduce this shielding effect and improve the effectiveness of signal acquisition, in the embodiment of the present application, a hole can be opened in the position corresponding to the metal plate on the vehicle outer side of the door sill; here, the corresponding position refers to the position where the sensor is close to the metal plate structure; the shape and size of the hole can be determined according to the shape and size of the sensor.

[0057] The hole will damage the original metal plate structure of the automobile, and in order to reduce the influence of the hole on the metal plate structure on the vehicle, such as reducing the inflow of rainwater into the hole to affect the normal operation of the vehicle, a non-metal material can be filled in the hole; the non-metal material is used to reduce the shielding of the signal and reduce the influence of the metal plate on signal acquisition. The present application does not limit the type of non-metal material used.

[0058] Furthermore, in the embodiments of this application, at least one sensor in the sensor group may include at least one of the following: radar, camera, antenna, and temperature sensor.

[0059] The radar can be different radars based on different technologies, such as one or more of lidar, millimeter-wave radar, and ultrasonic radar; the camera can be a camera with different field of view to increase the shooting range of the entire system; the antenna can be an antenna with different functions or transmitting different types of signals, such as a GNSS antenna used as a transmitting antenna in a co-frequency repeater system, or a 4G / 5G antenna used to transmit 4G / 5G signals; the temperature sensor can be used to detect the temperature inside and / or outside the vehicle, and specifically, it can also be used to detect the temperature of the area where the at least one signal acquisition device is located. The above sensor types / quantities are merely examples, and the at least one sensor included in the sensor group can also be other types, or a combination of multiple sensors. The specific type and number of sensors included do not affect the implementation of the embodiments of this application.

[0060] Furthermore, in this embodiment, at least one controller in the controller group may include at least one domain controller. In a vehicle, a "domain" refers to dividing the vehicle's electronic system into several functional blocks. Each functional block may have its own system architecture, which can be built around a domain controller. The domain controller is used to control components / devices in different domains of the vehicle. The domain controller may include a body domain controller, chassis domain controller, cockpit domain controller, powertrain domain controller, etc., or a combination of several domain controllers. The sensor type / number is merely an example; the at least one controller group included in the controller group may also be of other types, or a combination of multiple controller groups. The specific type and number of controller groups included do not affect the implementation of this embodiment.

[0061] In contrast to existing technologies, where multiple sensors and controllers are typically distributed across different locations within a vehicle, the cables used to transmit signals from the sensors are long and scattered throughout the vehicle. This results in these cables being bundled together with the power lines of other high-power devices, leading to electromagnetic interference affecting signal transmission. In this embodiment, however, a sensor group consisting of at least one sensor and a signal acquisition device consisting of a signal processor are located in the vehicle's door sill area, resulting in a more concentrated sensor area. At least one sensor in the sensor group sends its acquired signal to the processor, which then sends the processed signal to the controller group for vehicle control. The controller group is concentrated in the area between the passenger compartment floor and the interior carpet, thus consolidating the existing cable layout and reducing cable usage. This reduces electromagnetic interference caused by the bundled cables and high-power devices, improving the stability of vehicle control. Furthermore, it reduces the overall cable length and weight, thereby lowering costs.

[0062] Furthermore, in this embodiment of the application, the system may also include a supercapacitor; wherein the supercapacitor serves as a backup power source for the system, and the supercapacitor and the controller group are located in the same area.

[0063] Supercapacitors, also known as electrochemical capacitors, are electrochemical devices that store energy by polarizing an electrolyte. Unlike traditional chemical power sources, supercapacitors are a type of power source with unique properties, falling between traditional capacitors and batteries. They rely on the electric double layer and redox pseudocapacitive charges to store electrical energy. However, no chemical reaction occurs during the energy storage process in supercapacitors; this energy storage process is reversible, which is why supercapacitors can typically be charged and discharged hundreds of thousands of times. Supercapacitors are characterized by fast charging speeds and long lifespans.

[0064] The supercapacitor is located in the same area as the controller group, that is, in the area between the passenger compartment floor and the carpet in the car. The controller group and the supercapacitor are located in a relatively concentrated area, which helps to reduce the amount of cables used and facilitates the centralized distribution of cables, thereby reducing electromagnetic interference and improving the stability of car control.

[0065] Furthermore, in this embodiment, the at least one signal acquisition device may include four signal acquisition devices; the at least one signal acquisition device is located in different sill areas of the vehicle, and may include: the four signal acquisition devices are located in the left front sill, left rear sill, right front sill, and right rear sill areas of the vehicle, respectively. Currently, common vehicles have four doors. Setting four signal acquisition devices in the left front sill, left rear sill, right front sill, and right rear sill areas, distributing the sensors around the vehicle body, rather than just on one side, facilitates more comprehensive collection of signals around the vehicle, thereby enabling more rational / intelligent vehicle control. Moreover, distributing the sensors around the vehicle body can, to a certain extent, achieve full utilization of the vehicle space. It is understood that whether the at least one signal acquisition device meets the above-mentioned quantity and distribution does not affect the implementation of this embodiment.

[0066] Furthermore, when the at least one signal acquisition device includes multiple signal acquisition devices, the sensor groups included in the multiple signal acquisition devices may be identical, so as to improve the signal acquisition range without excessively increasing the space occupied by the sensors; or the included sensor groups may be different, to meet different signal acquisition requirements. It is understood that whether the at least one signal acquisition device satisfies the above-mentioned quantity and distribution does not affect the implementation of the embodiments of this application.

[0067] Furthermore, in this embodiment, the system may further include a heat dissipation device; wherein the heat dissipation device is used to dissipate heat for the system, and the heat dissipation device and the controller group are located in the same area. The heat dissipation device is located in the same area as the controller group, that is, in the area between the passenger compartment floor and the carpet in the car; since the controller group may generate a lot of heat during operation, placing the heat dissipation device in the same area as the controller group is beneficial for dissipating heat from the controller group, ensuring the normal operation of the controller group to a certain extent, thereby improving the stability of the entire system; compared with the prior art where multiple components have their own heat dissipation devices, in this embodiment, the heat dissipation devices are more concentratedly distributed in the same area as the controller group, which has the beneficial effect of reducing the space occupied by the heat dissipation devices and increasing the space available to passengers in the vehicle. It is understood that whether the system includes a heat dissipation device or not does not affect the implementation of this embodiment.

[0068] Furthermore, if the system also includes a heat dissipation device, the heat dissipation device may include a first heat dissipation device and a second heat dissipation device. See also... Figure 2 , Figure 1 This is a schematic diagram of the structure of an automotive electrical system provided in another embodiment of this application. For example...Figure 2 As shown, the components 201-210 included in the automotive electrical system 200 in this embodiment of the application respectively correspond to Figure 1 The components 101-110 of the China Automotive Electrical Systems Institute 100 are not described in detail here.

[0069] Figure 2 In the automotive electrical system 200, a first heat dissipation device 211 and a second heat dissipation device 212 are included. The first heat dissipation device 211 is located in front of the controller group, and the second heat dissipation device 212 is located behind the controller group. The front of the controller group is in the direction from the rear of the vehicle to the front of the vehicle. The air inlets and outlets of the first heat dissipation device 211 and the second heat dissipation device 212 have the same direction, and are both from the front of the controller group to the rear of the controller group, or from the rear of the controller group to the front of the controller group.

[0070] The front of the controller group faces the direction from the rear of the car to the front, and the rear of the controller group faces the direction from the front of the car to the rear. A heat dissipation device consisting of a first heat dissipation device 211 and a second heat dissipation device 212 is located on both sides of the controller group 202 to improve heat dissipation efficiency. The air inlets and outlets of the first and second heat dissipation devices 211 and 212 are arranged in the same direction to create air convection between the controller group 202, further improving heat dissipation efficiency. It is understood that whether or not the heat dissipation device is arranged in the above manner does not affect the implementation of the embodiments of this application.

[0071] Furthermore, in this embodiment, the system can be integrated into a single structural component. To reduce labor costs, the cable connectors, controller group including at least one controller, and at least one signal acquisition device in the system can be integrated into a single structural component. On the automotive assembly line, the structural component integrating the system can be directly installed on the vehicle. Compared to the prior art method of installing electrical components and wiring harnesses one by one on the production line, this embodiment can reduce the labor costs in the assembly plant and increase the installation cycle time of the production line. Furthermore, the structural component can also include backup power supplies, heat dissipation devices, and other components according to actual needs. It is understood that whether the system is integrated into a single structural component does not affect the implementation of this embodiment.

[0072] Furthermore, the heat dissipation device includes a first heat dissipation device and a second heat dissipation device. The first heat dissipation device is located in front of the controller group, and the second heat dissipation device is located behind the controller group. The front of the controller group is in the direction from the rear of the car to the front of the car. The system can be integrated into a single structural component, wherein the air inlets and outlets of the first and second heat dissipation devices have the same direction and are both in the direction from the front of the controller group to the rear of the controller group. On the structural component, corresponding to the left front sill, left rear sill, right front sill, and right rear sill areas of the car, air vents communicating with the outside of the system are provided.

[0073] Since the sensor group, processor, and controller group in the at least one signal acquisition device may also include other components, they are in a relatively concentrated distribution. While multiple components may be in a relatively concentrated distribution, heat dissipation for the entire system can improve the stability of the entire system's operation and, to a certain extent, ensure its normal operation. The air vents corresponding to the left front sill, left rear sill, right front sill, and right rear sill areas of the vehicle are connected to the outside of the system to increase airflow rate, thereby improving heat dissipation efficiency and promoting air circulation between the structural components and the outside of the system, thus enhancing the system's heat dissipation efficiency.

[0074] Furthermore, as the level of intelligent driving in automobiles increases, the types, quantities, and power consumption of components such as sensors, controllers, and backup power supplies required for intelligent driving gradually increase, and these components are typically distributed throughout the vehicle. In this situation, the cables for these components, scattered throughout the vehicle, are easily bundled together with the power cables of other high-power devices, making them susceptible to electromagnetic interference, reducing the stability of intelligent driving signal transmission, and affecting intelligent driving safety. Therefore, in the system described above, the sensors included in the sensor group of the signal acquisition device, and the controllers included in the controller group, can be sensors and controllers used to implement intelligent driving-related functions. The backup power supply and the heat dissipation device can be components used to provide functions related to intelligent driving. For example, the controller can be an intelligent driving controller used to control the vehicle to achieve functions related to intelligent driving.

[0079] The controller group 305 includes four domain controllers: body domain controller 3051, chassis domain controller 3052, cockpit domain controller 3053, and powertrain domain controller 3054.

[0080] The system is integrated into a structural component 306; the structural component 306 has a recess in the area partially enclosed by the left front sill area, the area where the controller group is located, and the left rear sill area; the structural component also has a recess in the area partially enclosed by the right front sill area, the area where the controller group is located, and the right rear sill area.

[0081] The system also includes a first heat dissipation device 307 and a second heat dissipation device 308.

[0082] The first heat dissipation device 307 is located in front of the controller group 305, and the second heat dissipation device 308 is located behind the controller group 305. The front of the controller group is in the direction from the rear of the car to the front of the car, and the rear of the controller group is in the direction from the front of the car to the rear of the car.

[0083] The first heat dissipation device 307 has an air inlet 3071 and an air outlet 3072, and the second heat dissipation device 308 has an air inlet 3081 and an air outlet 3082. Air enters the first heat dissipation device 307 through the air inlet 3071 and leaves the first heat dissipation device 307 through the air outlet 3072. During this process, the air flow direction is roughly from the front of the car to the rear of the car. Air enters the second heat dissipation device 308 through the air inlet 3081 and leaves the second heat dissipation device 308 through the air outlet 3082. During this process, the air flow direction is roughly from the front of the car to the rear of the car.

[0084] Since the first heat dissipation device 307 and the second heat dissipation device 308 are located in front of and behind the controller group 305 respectively, air in the area where the controller group 305 is located flows from the first heat dissipation device 307 to the controller group 305, and then to the second heat dissipation device 308.

[0085] On the structural component 306, corresponding to the left front sill, right front sill, left rear sill, and right rear sill areas of the automobile, air vents 309, 310, 311, and 312 are respectively provided. Air vents 309-312 are all connected to the outside of the system. Air vents 309 and 311 are opposite to each other so that air can be convected between them. Air vents 310 and 312 are opposite to each other so that air can be convected between them.

[0086] The flow to the second heat dissipation device 308 can enter the left rear door sill and right rear door sill areas where the third signal acquisition device 303 and the fourth signal acquisition device 304 are located, respectively. Air vents 311 and 312 are respectively provided for the left rear door sill and right rear door sill areas of the car.

[0087] Since air enters the left and right rear door sill areas through the second heat dissipation device 308, taking the left rear door sill area as an example, after the air enters the area, the air in the area is compressed and flows out to the external environment of the system through the air vent 311, which plays the role of accelerating the heat dissipation of the system.

[0088] Taking the left front door sill area as an example, after the air flows out of this area, the air pressure in this area decreases, and it flows from the external environment of the system into the left front door sill area through the air outlet 309, which accelerates the heat exchange between this area and the external environment of the system, and plays a role in accelerating the heat dissipation of the system.

[0089] Since vents 309 and 311 are opposite each other, and the space in the car body is limited, the distance between vents 309 and 311 is limited. Therefore, the air flowing out of the structural component from vent 311 and the air flowing into the structural component from vent 309 easily form airflow. Taking the left front sill area as an example, after the airflow between vents 311 and 309 enters this area, under the action of the first heat dissipation device 307, it further forms airflow with the airflow flowing from the first heat dissipation device 307 to the second heat dissipation device 308, and enters the left rear sill area and the right rear sill area respectively. Therefore, for the left side of the car, the first cooling device 307, controller group 305, second cooling device 308, left rear sill area, left front sill area, and the first cooling device 305 sequentially form a circulating airflow; similarly, the right side of the car also forms a circulating airflow through the first cooling device 307, controller group 305, second cooling device 308, right rear sill area, right front sill area, and the first cooling device 307, thereby improving the system's heat dissipation efficiency. In summary, although the components in the system are relatively concentrated in this embodiment, high-efficiency heat dissipation can be achieved through a certain method while saving space occupied by the cooling devices. The same principle applies to the accelerated heat dissipation of the other three sill areas.

[0090] The system 300 also includes a supercapacitor; wherein the supercapacitor serves as a backup power source for the system 300, and the supercapacitor and the controller group 305 are located in the same area;

[0091] The controller group 305 is located in the area between the passenger compartment floor and the interior carpet of the vehicle, and is connected to the vehicle wiring harness outside the system via the cable connector 313; wherein, at least one controller in the controller group 305 is used to control the vehicle according to the received target signal.

Various modifications to these embodiments will be readily 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 this application.
