Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a vehicle integrated controller system and a vehicle. Background Technology

[0002] In related technologies, with the development of the times, vehicles have gradually become an indispensable necessity in modern life. As vehicles become increasingly integrated into daily life, people are placing higher demands on various details of vehicles. Furthermore, as vehicles themselves become more intelligent with technological advancements, the number of control units installed in vehicles to control different functional modules is also increasing.

[0003] However, how to improve the processing capabilities of various control units and make the most of their computing power remains an urgent problem to be solved. Summary of the Invention

[0004] This application provides a vehicle integrated controller system and a vehicle.

[0005] According to a first aspect of the embodiments of this application, a vehicle integrated controller system is provided for controlling different functional modules of a vehicle, including a central controller. The central controller includes a central control circuit board and multiple central control units integrated on the central control circuit board. The system includes domain controllers that are independently configured and electrically connected to the central controller.

[0006] The domain controller includes a domain control circuit board and multiple domain control units integrated on the domain control circuit board.

[0007] The domain control unit is used to control low-power functional modules. The central control unit is used to control high-power functional modules.

[0008] As can be seen from the embodiments of this application, by integrating the domain control unit for controlling low-power functional modules and the central control unit for controlling high-power functional modules into the central controller and domain controller respectively, control units with similar power can be integrated together. Since control units with similar power also have similar energy consumption, operating temperature, and heat dissipation requirements, based on the separate integration of the domain control unit and the central control unit, separate power supply and heat dissipation systems can be set for the central controller and the domain controller. This allows the domain control unit and the central control unit to operate within their respective optimal temperature ranges and unify their power supply requirements, thereby improving the efficiency of the domain control unit and the central control unit, and increasing the computing power of each control unit. Furthermore, it can reduce the complexity of the power supply circuitry, thereby reducing process difficulty and manufacturing costs.

[0009] In some embodiments, the domain controller is located closer to the functional module than the central controller.

[0010] This configuration, by integrating the domain control unit into the domain controller and placing the domain controller closer to the functional modules than the central controller, allows functional modules that are far from the central controller's wiring harness to be electrically connected to the domain controller. The domain controller is then electrically connected to the central controller via a wiring harness. This reduces the required wiring harness length compared to directly connecting the functional modules to the central controller, thereby reducing the length of the wiring harness laid out in the vehicle, simplifying the vehicle's wiring design, and reducing the interior space occupied by the wiring harness.

[0011] In some embodiments, the domain controller includes a left domain controller and a right domain controller.

[0012] The left domain controller is located to the left of the central controller, and the right domain controller is located to the right of the central controller.

[0013] This configuration, by setting up left and right domain controllers, allows functional modules located on the left and right sides of the central controller to be electrically connected to either the left or right domain controller. This further reduces the required wiring harness length compared to directly connecting the functional modules to the central controller, thereby further reducing the length of the wiring harness arranged in the vehicle, reducing the difficulty of vehicle wiring design, and reducing the interior space occupied by the wiring harness.

[0014] In some embodiments, the left domain controller and the right domain controller are symmetrically arranged on both sides of the central controller.

[0015] This configuration allows the installation of the vehicle integrated controller system to be compatible with both left-hand drive and right-hand drive vehicles, thereby simplifying vehicle manufacturing and reducing production costs.

[0016] In some embodiments, the left domain controller, the right domain controller, and the central controller are used to control different functional modules.

[0017] This configuration avoids overlap between the functional modules controlled by the left domain controller, right domain controller, and central controller. In particular, it avoids overlap between the functional modules controlled by the left domain controller and right domain controller, thus avoiding the need to add wiring harnesses to electrically connect the left domain controller and right domain controller.

[0018] In some embodiments, the power of the low-power functional module is less than or equal to 180 watts, and the power of the high-power functional module is greater than 180 watts.

[0019] This configuration, based on the separate integration of the domain control unit and the central control unit, allows for the provision of separate power supply and cooling systems for the central controller and the domain controller. This enables the domain control unit and the central control unit to operate within their respective optimal temperature ranges and to unify their power supply requirements. Consequently, it can improve the efficiency of the domain control unit and the central control unit, thereby enhancing the computing power of each control unit.

[0020] In some embodiments, at least a portion of the domain control unit is used to control a plurality of low-power functional modules. At least a portion of the central control unit is used to control a plurality of high-power functional modules.

[0021] This configuration, by having at least some domain control units control multiple low-power functional modules and at least some central control units control multiple high-power functional modules, allows different control commands to be executed by calling the same domain control unit or central control unit. This improves the overall computing power utilization efficiency of the vehicle integrated controller system, thereby achieving better control results with the same or even fewer control units.

[0022] According to a second aspect of the embodiments of this application, a vehicle is provided, including any of the above-described vehicle integrated controller systems. It further includes a front body pillar and a firewall, the firewall being located between the passenger space and the engine space of the vehicle, and the front body pillar being connected to the firewall.

[0023] The central controller is located within the passenger compartment of the vehicle, on the vehicle's central axis, and close to the firewall. The central controller is water-cooled.

[0024] This configuration shortens the wiring distance between the central controller and the high-power functional modules. This allows for a shorter wiring harness to electrically connect the central controller and the high-power functional modules, further reducing the number of wiring harnesses within the vehicle, simplifying wiring design, and minimizing the space occupied by the wiring harnesses. Furthermore, since the central controller is located on the vehicle's central axis, it also prevents it from interfering with the seating arrangement in the passenger compartment.

[0025] In some embodiments, an engine cooling system located in the engine space of the vehicle is also included. The central controller further includes a controller cooling system. The engine cooling system and the controller cooling system are interconnected.

[0026] This design allows the coolant within the engine cooling system to dissipate heat from the central controller, thereby improving the controller's cooling system's heat dissipation capacity. This, in turn, effectively removes the heat generated by the central controller, preventing overheating and ensuring its proper operation. Furthermore, it simplifies the overall structure of the engine and controller cooling systems, thus reducing the manufacturing difficulty and cost of the controller cooling system.

[0027] In some embodiments, the vehicle includes a floor. The front pillars include a left front pillar and a right front pillar. The passenger space includes foot space located on either side of the central controller and close to the floor.

[0028] The left domain controller is positioned on the left front pillar, close to the firewall. The right domain controller is positioned on the right front pillar, close to the firewall. The left and right domain controllers are located above the footwell.

[0029] This configuration allows the domain controller to be supported by a stronger front body pillar, thereby improving the stability of the domain controller.

[0030] In some embodiments, the vehicle includes a floor. The front body pillars include a left front body pillar and a right front body pillar. The domain controller includes a left domain controller and a right domain controller located on either side of the central controller. The passenger space includes foot space located on either side of the central controller and close to the floor. The left domain controller and the right domain controller are located above the foot space.

[0031] When the vehicle is left-hand drive, the left domain controller is located on the left front pillar and close to the firewall. The right domain controller is located on the firewall, close to the upper part of the firewall and away from the right front pillar.

[0032] When the vehicle is right-hand drive, the right domain controller is located on the right front pillar and close to the firewall. The left domain controller is located on the firewall, close to the upper part of the firewall and away from the left front pillar.

[0033] This configuration, when applied to left-hand drive vehicles, allows the left-hand control unit, located on the driver's side, to be integrated into the vehicle's instrument panel structure. Furthermore, it frees up legroom, thereby improving the passenger's comfort.

[0034] In some embodiments, the left domain controller is used to control at least one of the vehicle control module, driver control module, interior light control module, electric vehicle AC control module, left airbag seat belt control module, high-voltage charging and DC / DC conversion control module, and trailer control module.

[0035] The right domain controller is used to control at least one of the air conditioning control module, the passenger seat control module, and the right airbag seat belt control module.

[0036] The central controller is used to control at least one of the following modules: driving information and entertainment host module, intelligent driving control module, vehicle gateway module, parking assistance module, wide-angle vision module, driving recorder module, driver status monitoring and control module, rain sensor module, combination switch control module, in-vehicle infotainment display module, driving information display module, and rear seat entertainment control module.

[0037] With this setup, most of the functional modules of the vehicle 20 can be controlled through the left domain controller, right domain controller and central controller, thus achieving a high degree of integrated control of the entire vehicle.

[0038] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0045] This application provides a vehicle integrated controller system 10. Figure 1 This is a schematic diagram of the vehicle integrated controller system 10. (As shown...) Figure 1 As shown, the vehicle integrated controller system 10 is used to control different functional modules of the vehicle, including a central controller 11. The central controller 11 includes a central control circuit board (not shown in the figure) and multiple central control units (not shown in the figure) integrated on the central control circuit board.

[0046] Specifically, the functional modules controlled by the vehicle integrated controller system 10 may include: a vehicle control module, a driver control module, an interior light control module, an electric vehicle AC control module, a left-side airbag seatbelt control module, a high-voltage charging and DC / DC conversion control module, a trailer control module, an air conditioning control module, a passenger seat control module, a right-side airbag seatbelt control module, a driving information and entertainment host module, an intelligent driving control module, a vehicle gateway module, a parking assistance module, a wide-angle viewing module, a driving recorder module, a driver status monitoring control module, a rain sensor module, a combination switch control module, an in-vehicle infotainment display module, a driving information display module, and a rear seat entertainment control module.

[0047] The vehicle integrated controller system 10 also includes a domain controller 12 that is independently configured and electrically connected to the central controller 11.

[0048] The domain controller 12 includes a domain control circuit board 121 and a plurality of domain control units 122 integrated on the domain control circuit board 121.

[0049] Domain control unit 122 is used to control low-power functional modules. Central control unit is used to control high-power functional modules.

[0050] Because vehicles contain functional modules with varying power ratings, the control units used to control these modules also have different power requirements. Low-power modules require control by low-power control units, while high-power modules require control by high-power control units. These control units differ significantly in energy consumption, operating temperature, and heat dissipation requirements. Integrating these control units together can easily lead to discrepancies in energy consumption, operating temperature, and heat dissipation requirements, making it difficult for each control unit to operate within its optimal temperature range. Furthermore, the varying power supply requirements increase the complexity of the power supply circuitry, raising manufacturing difficulty and production costs.

[0051] By integrating the domain control unit 122, which controls low-power functional modules, and the central control unit, which controls high-power functional modules, into the central controller 11 and domain controller 12 respectively, control units with similar power can be integrated together. Since control units with similar power also have similar energy consumption, operating temperature, and heat dissipation requirements, by integrating the domain control unit 122 and the central control unit, separate power supply and heat dissipation systems can be set for the central controller 11 and the domain controller 12. This allows the domain control unit 122 and the central control unit to operate within their respective optimal temperature ranges and unify their power supply requirements, thereby improving the efficiency of the domain control unit 122 and the central control unit, and increasing the computing power of each control unit. Furthermore, it reduces the complexity of the power supply circuitry, thus reducing manufacturing difficulty and costs.

[0052] In some embodiments, such as Figure 1 As shown, the domain controller 12 is positioned closer to the functional modules than the central controller 11.

[0053] Because the central controller 11 is functionally critical and occupies a significant amount of space, it inevitably needs to be designed along the vehicle's central axis. To control the functional modules within the vehicle, wiring harnesses are required to electrically connect the central controller 11 and the functional modules. However, the distance between the wiring harnesses and the central controller 11 varies; some functional modules require longer distances and traverse more structures. This makes the wiring harness layout complex and increases the difficulty of vehicle wiring design. Furthermore, the wiring harness itself requires considerable interior space for routing, inevitably affecting the layout of the passenger space. The wiring harness distance refers to the length of the wiring harness required to electrically connect the functional modules and the control unit.

[0054] By integrating the domain control unit 122 into the domain controller 12, and positioning the domain controller 12 closer to the functional modules than the central controller 11, functional modules that are far from the wiring harness of the central controller 11 can be electrically connected to the domain controller 12. The domain controller 12 is then electrically connected to the central controller 11 via a wiring harness. This reduces the required wiring harness length compared to directly connecting the functional modules to the central controller 11, thereby reducing the length of the wiring harness arranged in the vehicle, simplifying the vehicle's wiring design, and reducing the interior space occupied by the wiring harness.

[0055] In some embodiments, such as Figure 1 As shown, domain controller 12 includes a left domain controller 123 and a right domain controller 124.

[0056] The left domain controller 123 is located to the left of the central controller 11, and the right domain controller 124 is located to the right of the central controller 11. Figure 1 The diagram shows axis Y, which passes through the central axis of central controller 11. The left side of axis Y is left domain Y1, and the right side is right domain Y2. Therefore, the left side of central controller 11 is left domain Y1, and the right side of central controller 11 is right domain Y2. Left domain controller 123 is located in left domain Y1, and right domain controller 124 is located in right domain Y2.

[0057] By setting up the left domain controller 123 and the right domain controller 124, the functional modules located on the left and right sides of the central controller 11 can be electrically connected to the left domain controller 123 or the right domain controller 124 nearby. This can further reduce the required wiring harness length compared to directly connecting the functional modules to the central controller 11, thereby further reducing the length of the wiring harness arranged in the vehicle, reducing the difficulty of vehicle wiring design, and reducing the interior space occupied by the wiring harness.

[0058] After repeated experiments and calculations, the inventors discovered that this integrated design can reduce the overall wiring harness length of a vehicle by nearly one kilometer.

[0059] In some embodiments, the left domain controller 123 and the right domain controller 124 are symmetrically arranged on both sides of the central controller 11. (See reference) Figure 1 As shown, the left domain controller 123 and the right domain controller 124 are symmetrically arranged on both sides of the Y-axis.

[0060] This configuration allows the vehicle integrated controller system 10 to be installed in both left-hand drive and right-hand drive vehicles, thereby simplifying vehicle manufacturing and reducing production costs.

[0061] In some embodiments, the left domain controller 123, the right domain controller 124, and the central controller 11 are used to control different functional modules.

[0062] Specifically, the left domain controller 123 can be used to control: the vehicle control module, the driver control module, the interior light control module, the electric vehicle AC control module, the left airbag seat belt control module, the high-voltage charging and DC / DC conversion control module, and the trailer control module.

[0063] The right domain controller 124 can be used to control: the air conditioning control module, the passenger seat control module, and the right airbag seat belt control module.

[0064] The central controller 11 can be used to control: the driving information and entertainment host module, the intelligent driving control module, the vehicle gateway module, the parking assistance module, the wide-angle viewing module, the driving recorder module, the driver status monitoring and control module, the rain sensor module, the combination switch control module, the in-vehicle infotainment display module, the driving information display module, and the rear seat entertainment control module.

[0065] This configuration avoids overlap between the functional modules controlled by the left domain controller 123, the right domain controller 124 and the central controller 11. In particular, it avoids overlap between the functional modules controlled by the left domain controller 123 and the right domain controller 124, thus avoiding the need to add wiring harnesses to electrically connect the left domain controller 123 and the right domain controller 124.

[0066] In some embodiments, the power of a low-power functional module is less than or equal to 180 watts, and the power of a high-power functional module is greater than 180 watts.

[0067] Specifically, a very small number of functional modules controlled by domain controller 12 may have higher power, while the vast majority of functional modules controlled by domain controller 12 are low-power. Therefore, domain control unit 122 is still considered to be used to control low-power functional modules. For example, the trailer control module controlled by domain controller 12 is controlled by domain controller 12 because the wiring harness distance from the central controller 11 is too long. However, the domain control units 122 that control other modules besides the trailer control module have lower power. Therefore, domain control unit 122 is still considered to be used to control low-power functional modules.

[0068] With this configuration, based on the integration of the domain control unit 122 and the central control unit, the central controller 11 and the domain controller 12 can be equipped with their own power supply and heat dissipation systems. This allows the domain control unit 122 and the central control unit to operate in their respective optimal temperature ranges and unify their power supply requirements. Consequently, the efficiency of the domain control unit 122 and the central control unit can be improved, thereby enhancing the computing power of each control unit.

[0069] In some embodiments, at least some domain control units 122 are used to control multiple low-power functional modules. At least some central control units are used to control multiple high-power functional modules. That is, some domain control units 122 may be used to control multiple low-power functional modules, or all domain control units 122 may be used to control multiple low-power functional modules. Similarly, some central control units may be used to control multiple high-power functional modules, or all central control units may be used to control multiple high-power functional modules.

[0070] When the control unit is only electrically connected to a functional module, if the functional module does not need to function, the control unit will not be in operation, and its computing power will be idle. This obviously leads to a waste of the control unit's computing power, thus reducing the overall computing power utilization efficiency of the vehicle integrated controller system 10.

[0071] By using at least some domain control units 122 to control multiple low-power functional modules and at least some central control units to control multiple high-power functional modules, different control commands can be executed by calling the same domain control unit 122 or central control unit, thereby improving the overall computing power utilization efficiency of the vehicle integrated controller system 10. As a result, better control effects can be achieved by using the same or even fewer domain control units 122 or central control units.

[0072] The aforementioned better control effect means that the computational load can be shared by multiple domain control units 122 or central control units to achieve a faster response speed, and that the same task can be performed by calling more domain control units 122 or central control units to maintain normal control after some control units are damaged, thus achieving system safety redundancy, but not limited to this.

[0073] This application also provides a vehicle 20. The vehicle includes any of the aforementioned vehicle integrated controller systems 10. Furthermore, as... Figure 1 As shown, the vehicle also includes a front body pillar 21 and a firewall 22. The front body pillar 21 is the commonly known A-pillar structure of a car.

[0074] Firewall 22 is located between the passenger space 201 and the engine space (not shown) of vehicle 20, and the front body pillar 21 is connected to firewall 22. That is, firewall 22 also serves to separate the passenger space 201 and the engine space of vehicle 20.

[0075] The central controller 11 is located within the passenger space of the vehicle 20, on the central axis of the vehicle 20, and close to the firewall 22. That is, the central controller 11 is located on the central axis of the vehicle, and the axis Y is also the central axis of the vehicle.

[0076] Since the high-power functional modules that are electrically connected to the central controller 11 within the vehicle 20 are generally located directly on the side of the firewall 22 facing the passenger space, placing the central controller 11 close to the firewall 22 can shorten the wiring distance between the central controller 11 and the high-power functional modules. This allows for a shorter wiring harness to be used to electrically connect the central controller 11 and the high-power functional modules, further reducing the number of wiring harnesses within the vehicle, simplifying the wiring design, and minimizing the interior space occupied by the wiring harnesses. Furthermore, since the central controller 11 is located on the central axis of the vehicle 20, it also prevents the central controller 11 from interfering with the seating arrangement within the passenger space 201.

[0077] In some embodiments, Figure 2 A partial enlarged view of the central controller 11 within the passenger compartment 201 is shown. Figure 3 The diagram shows the connection between the controller cooling system 111 and the engine cooling system 30. (See attached diagram.) Figure 1 , Figure 2 and Figure 3 As shown, vehicle 20 also includes an engine cooling system (not shown) located in the engine space of vehicle 20. Central controller 11 also includes controller cooling system 111. The engine cooling system and controller cooling system 111 are interconnected.

[0078] Specifically, the controller cooling system 111 also includes a cooling pipe 112 and a connecting hole 23 disposed on the firewall 22. The cooling pipe 112 extends into the engine space through the connecting hole 23 and connects to the engine cooling system 30, so as to realize the interconnection between the engine cooling system 30 and the controller cooling system 111.

[0079] Among them, reference Figure 4 The diagram shows a partial structure of the engine cooling system 30. The engine cooling system 30 includes a valve 31 and an engine cooling pipe 32. Coolant enters the cooling pipe 112 from the engine cooling pipe through the valve 31, cooling the central controller 11. The valve 31 can be a solenoid valve and is used to control the flow rate of coolant dissipating heat from the central controller 11. By adjusting the coolant flow rate in the cooling pipe 112 according to the heat generated by the central controller 11 under different operating conditions, the central control unit can be kept operating within its optimal temperature range, thereby improving its computing power.

[0080] Since the engine cooling system and the controller cooling system 111 are interconnected, the coolant in the engine cooling system can dissipate heat from the central controller 11. Furthermore, because the engine cooling system is responsible for cooling the engine, its heat dissipation capacity is stronger than that of typical electronic device cooling systems. This enhances the heat dissipation capacity of the controller cooling system 111, allowing for timely removal of the heat generated by the central controller 11 and preventing overheating that could affect its operation.

[0081] Furthermore, since the engine cooling system and the controller cooling system 111 are interconnected, there is no need to set up a separate condenser or other structure for the controller cooling system 111, which simplifies the overall structure of the engine cooling system and the controller cooling system 111. As a result, the manufacturing difficulty and manufacturing cost of the controller cooling system 111 can be reduced.

[0082] In some embodiments, such as Figure 1 As shown, vehicle 20 includes floor 24. Front body pillars 21 include left front body pillar 211 and right front body pillar 212. Passenger space 201 includes foot space 202, which is located on both sides of central controller 11 and close to floor 24.

[0083] The left domain controller 123 is located on the left front pillar 211, near the firewall 22. The right domain controller 124 is located on the right front pillar 212, near the firewall 22. The left domain controller 123 and the right domain controller 124 are located above the footwell 202.

[0084] By positioning the left domain controller 123 and the right domain controller 124 on opposite sides of axis Y, the vehicle integrated controller system 10 can be compatible with both left-hand drive and right-hand drive vehicles, thereby simplifying vehicle manufacturing and reducing production costs. Furthermore, since the left domain controller 123 and the right domain controller 124 are located above the footwell 202, the domain controller 12 is prevented from occupying the footwell 202, thus providing ample footwell space 202 for the driver and passengers in the passenger compartment 201 and improving the riding experience.

[0085] Meanwhile, since the strength of the front body pillar 21 is generally much greater than that of structures such as the firewall 22, placing the domain controller 12 close to the front body pillar 21 allows the stronger front body pillar 21 to provide support for the domain controller 12, thereby improving the stability of the domain controller 12.

[0086] In some embodiments, such as Figure 1As shown, vehicle 20 includes a floor 24. Front pillars 21 include a left front pillar 211 and a right front pillar 212. Domain controller 12 includes a left domain controller 123 and a right domain controller 124 located on either side of the central controller 11. Passenger space 201 includes foot space 202 located on either side of the central controller 11 and close to the floor 24. Left domain controller 123 and right domain controller 124 are located above the foot space 202.

[0087] When vehicle 20 is left-hand drive, the left domain controller 123 is located on the left front pillar 211 and close to the firewall 22. The right domain controller 124 is located on the firewall 22, close to the upper part of the firewall 22 and away from the right front pillar 212.

[0088] When vehicle 20 is a right-hand drive vehicle, the right domain controller 124 is located on the right front pillar 212, close to the firewall 22. The left domain controller 123 is located on the firewall 22, close to the upper part of the firewall 22, and away from the left front pillar 211.

[0089] With this configuration, when applied to a left-hand drive vehicle, the left domain controller 123, being located on the driver's side, can be integrated into the dashboard structure of the vehicle 20.

[0090] Furthermore, when the front passenger seat is reclined, the passenger's legs are raised quite high. If the right-side controller 124 is positioned on the right front pillar 212, it may inadvertently interfere with the passenger's legs, affecting their comfort. Positioning the right-side controller 124 on the firewall 22 further frees up legroom 202, thus improving the front passenger's comfort. The advantages of applying this to right-hand drive vehicles are similar to those for left-hand drive vehicles.

[0091] In some embodiments, the left domain controller 123 is used to control at least one of the vehicle control module, driver control module, interior light control module, electric vehicle AC control module, left side airbag seat belt control module, high voltage charging and DC / DC conversion control module, and trailer control module.

[0092] The right domain controller 124 is used to control at least one of the air conditioning control module, the passenger seat control module, and the right airbag seat belt control module.

[0093] The central controller 11 is used to control at least one of the following modules: driving information and entertainment host module, intelligent driving control module, vehicle gateway module, parking assistance module, wide-angle vision module, driving recorder module, driver status monitoring and control module, rain sensor module, combination switch control module, in-vehicle infotainment display module, driving information display module and rear seat entertainment control module.

[0094] Preferably, the left domain controller 123, the right domain controller 124, and the central controller 11 are each used to control all the aforementioned functional modules. Thus, most of the functional modules of the vehicle 20 can be controlled through the left domain controller 123, the right domain controller 124, and the central controller 11, thereby achieving highly integrated control of the entire vehicle.

[0095] In some embodiments, certain functional modules are not controlled by the central controller 11 or the domain controller 12, such as the door unlocking module and the fuse box module.

[0096] After conducting forward collision safety simulation experiments, the inventors removed some functional modules that required higher system redundancy when vehicle 20 collided from the central controller 11 and domain controller 12, thereby improving the safety performance of vehicle 20.

[0097] The above embodiments of this application can complement each other without causing conflict.

[0098] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers.
