For example, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Communication connection" can be a wired communication connection or a wireless communication connection.

[0028] In addition, in the subsequent description, the use of suffixes such as "module" or "unit" to represent elements is only to facilitate the description of the present application, and has no specific meaning. Therefore, the terms "module" or "unit" can be used mixedly.

[0029] The vehicle described in the present disclosure, without departing from the basic structure of the vehicle, may refer to various types of vehicles, such as passenger cars or commercial vehicles, road vehicles or off-road vehicles; the vehicle may be a hybrid vehicle, a non-hybrid vehicle, an electric vehicle, a fuel cell vehicle or a vehicle of other power types. The vehicle may be an autonomous vehicle, a semi-autonomous vehicle or a non-autonomous vehicle.

[0030] In some exemplary embodiments of the present disclosure, the vehicle is an engineering transport vehicle, such as an off-road dump truck. At present, the electronic and electrical architecture of the off-road dump truck mostly adopts the connection mode of physical lines, and each control unit is divided according to function, and is independent of each other, and controls the engine, brake, steering, battery, door, air conditioning and other components respectively. Each functional unit is connected to each other through a wire harness, and information exchange is realized through a predefined communication protocol.

[0031] However, as the country develops dump trucks for green mines towards intelligence, efficiency, and safety, this electronic and electrical architecture has gradually exposed many problems. For example, with the increase in the application of electronic and electrical products in the whole vehicle, the number of electronic control units (ECUs) has increased significantly. The longer the corresponding wire harness length, the more complex the wiring, and the increased weight of the wire harness. Moreover, the complexity of the wire harness leads to a high failure rate, difficulty in troubleshooting, and is not conducive to maintenance. In addition, the electronic and electrical architecture in which each functional unit is connected by a wire harness often lacks efficient communication and data combing capabilities, which limits the performance and intelligence level of the vehicle and cannot meet the needs of autonomous driving and unmanned driving.

[0032] In view of the above problems, the present disclosure provides an electronic and electrical architecture of a vehicle, referring to Figure 1 As shown, it includes: a power module, a first power distribution domain control module 21 and a second power distribution domain control module 22. The first power distribution domain control module 21 is connected to the power module, and the first power distribution domain control module 21 is configured to supply power to the vehicle controller 3; the first power distribution domain control module 21 is also configured to control the power distribution of the electrical components in the cab of the vehicle; the second power distribution domain control module 22 is connected to the power module, and the second power distribution domain control module 22 is configured to control the power distribution of the electrical components in the chassis of the vehicle.

[0033] The electronic and electrical architecture of the vehicle provided by the present disclosure divides the electrical appliances into electrical components in the cab and electrical components in the chassis according to the physical locations of the various electrical appliances on the vehicle, manages and distributes the power supply to the electrical components in the cab through the first power distribution domain control module 21, and manages and distributes the power supply to the electrical components in the chassis through the second power distribution domain control module 22. On the one hand, the wiring harness can be arranged nearby, the number and length of the wiring harness of the whole vehicle can be reduced, and the failure rate can be reduced; on the other hand, compared with the traditional distribution box, the first power distribution domain control module 21 and the second power distribution domain control module 22 cancel the fuse and relay, and the power supply distribution of the electrical appliances can be realized based on electronic devices. The program can be customized according to the needs, so that the pin functions of the first power distribution domain control module 21 and the second power distribution domain control module 22 can be configured according to the different functions of the vehicle, and the digitalization of the vehicle distribution system can be realized, laying the foundation for the digitalization of the vehicle. In addition, by supplying power to electrical appliances through the first distribution domain control module 21 and the second distribution domain control module 22, the electronic control unit can directly control the load without going through a relay, thereby integrating line protection and control, which is beneficial for controlling and monitoring the power supply line and facilitating fault detection and diagnosis.

[0034] In particular, for off-road wide-body dump trucks, which often work in scenarios such as open-pit mines, the electronic and electrical architecture disclosed in the present invention has higher flexibility and compatibility for remote monitoring, fault diagnosis, and subsequent functional upgrades and expansions of the dump trucks, and can enhance the communication and data processing capabilities of the electrical control system to meet the needs of high performance and intelligence of the vehicle.

[0035] Specifically, the first power distribution domain control module 21 may include one or more first power distribution domain controllers, and the first power distribution domain controller may include a microprocessor, a power circuit, a communication interface, and a non-volatile memory, which is used to process the signal input to the first power distribution domain control module 21, and execute the algorithm obtained through the communication interface or stored in the non-volatile memory to manage and distribute the power supply of the electrical components in the cab. The first power distribution domain controller may also include hardware required for other services. Exemplarily, the second power distribution domain control module 22 may also include one or more second power distribution domain controllers, and the hardware structure of the second power distribution domain controller may be similar to that of the first power distribution domain controller, for example, including a microprocessor, a power circuit, a communication interface, and a non-volatile memory. Each pin of the second power distribution domain controller may be configured according to the number, signal type, and power of the chassis electrical components, and is used to process the signal input to the second power distribution domain control module 22, and execute the corresponding algorithm to manage and distribute the power supply of the chassis electrical components. Of course, the second power distribution domain controller may also include hardware required for other services.

[0036] The power module may include a battery 1, and the battery 1 is connected to the first power distribution domain control module 21 and the second power distribution domain control module 22 respectively. The first power distribution domain control module 21 can supply the low-voltage electricity provided by the battery 1 to the low-voltage power-consuming components in the cab; the second power distribution domain control module 22 can supply the low-voltage electricity provided by the battery 1 to the low-voltage power-consuming components on the chassis. Exemplarily, for non-electric vehicles, the power module may also include a generator, and the generator may be connected to the first power distribution domain control module 21 and the second power distribution domain control module 22 in parallel with the battery 1 to supply power to the first power distribution domain control module 21 and the second power distribution domain control module 22. Exemplarily, for new energy vehicles, the power module may also include a power battery and a DC / DC converter, the input end of the DC / DC converter may be connected to the power battery through a high-voltage distribution box, and the output end of the DC / DC converter may be connected to the first power distribution domain control module 21 and the second power distribution domain control module 22 in parallel with the battery 1 to supply power to the first power distribution domain control module 21 and the second power distribution domain control module 22.

[0037] The vehicle control unit 3 (VCU) is the core control unit of the vehicle. A high-performance microprocessor can be used as the core controller to receive and process signals from various systems on the vehicle, and to control the vehicle as a whole through preset algorithms and control strategies. In an exemplary embodiment of the present disclosure, the vehicle control unit 3 also supports the transmission of all data to the unmanned driving background.

[0038] In an exemplary embodiment of the present disclosure, reference Figure 1 As shown, the first power distribution domain control module 21 and the second power distribution domain control module 22 are both connected to the vehicle controller 3 via CAN communication. Specifically, the communication interface of each first power distribution domain controller can be connected to the vehicle controller 3 via CAN communication, and the communication interface of each second power distribution domain controller can be connected to the vehicle controller 3 via CAN communication. The vehicle controller 3 can output control instructions to the first power distribution domain control module 21 through the controller area network (CAN) bus to control the first power distribution domain control module 21 to distribute power to electrical components in the cab; the vehicle controller 3 can output control instructions to the second power distribution domain control module 22 through the CAN bus to control the second power distribution domain control module 22 to distribute power to electrical components in the cab.

[0039] In an exemplary embodiment of the present disclosure, the first power distribution domain control module 21 and the second power distribution domain control module 22 may also input the vehicle status information to the vehicle controller 3 via the CAN bus. Figure 1 As shown, the first power distribution domain control module 21, the second power distribution domain control module 22 and the vehicle controller 3 can communicate through the CAN bus to achieve data transmission and processing, thereby reducing the vehicle wiring harness, reducing vehicle failure points, and improving the flexibility of the vehicle wiring harness layout and circuit reliability. In an exemplary embodiment of the present disclosure, the vehicle controller 3 can wake up the first power distribution domain control module 21 and the second power distribution domain control module 22, and interact and transmit messages with the first power distribution domain control module 21 and the second power distribution domain control module 22.

[0040] Exemplarily, the electronic and electrical architecture of the vehicle includes multiple sensors. Sensors are divided into cab sensors and chassis sensors according to their physical locations; the cab sensor is connected to the first power distribution domain control module 21, for example, connected to the signal input pin of the first power distribution domain controller, and the first power distribution domain control module 21 is used to obtain the sensor signal of the cab sensor; the chassis sensor is connected to the second power distribution domain control module 22, for example, connected to the signal input pin of the second power distribution domain controller, and the second power distribution domain control module 22 is used to obtain the sensor signal of the chassis sensor. The sensor signal of the cab sensor may include, for example, a temperature signal, a light switch signal, a horn switch signal, a wiper switch signal, etc.; the sensor signal of the chassis sensor may include, for example, a cargo box proximity switch signal, an air pressure alarm signal, a light horn signal light at the rear of the vehicle, etc. Specifically, the types of sensors may include air pressure sensors, pressure transmitters, proximity switches, thermistors, inclinometers and other sensors.

[0041] Exemplarily, depending on the type of vehicle, the sensor signal of the cab sensor is also different, and the pin information of the first power distribution domain control module 21 can be configured according to the needs of the vehicle. For example, the number of input pins of the first power distribution domain control module 21 is configured to match the number of input signals of the cab sensor. Specifically, according to the number and type of input signals of the cab sensor, the first power distribution domain control module 21 may include one or more first power distribution domain controllers, and according to the type and number of input signals of the cab sensor, the number of digital switch quantities and the properties of the digital switch quantities, the number of analog quantities and the properties of the analog quantities of each first power distribution domain controller in the first power distribution domain control module 21 are set accordingly.

[0042] For another example, depending on the type of vehicle, the electrical components in the cab are also different, and the number of output pins of the first power distribution domain control module 21 is configured to match the number of loads connected to the first power distribution domain control module 21. Specifically, the number of output pins of each first power distribution domain controller is configured according to the number of loads in the cab. Exemplarily, the output pins of each first power distribution domain controller may include a plurality of configurable power supply pins, and the output pins may be configured to normal power, power controlled by CAN messages, or power controlled by one or more input pin signals, etc., through the host computer, so as to meet the power supply requirements of the electrical components in the cab.

[0043] Exemplarily, the total power output of the first power distribution domain control module 21 is configured to match the total power of the load connected to the first power distribution domain control module 21. This ensures that the first power distribution domain control module 21 can stably supply power to the electrical components in the cab.

[0044] At the same time, the input signal of the cab sensor connected to the input pin of the first power distribution domain control module 21 and the state of the output pin of the first power distribution domain control module 21 can interact with the vehicle control unit, including but not limited to the vehicle controller 3, through the communication bus. Exemplarily, the first power distribution domain control module 21 can interact with the vehicle controller 3 through CAN communication. Exemplarily, the local area network and Ethernet of the vehicle controller 3 can communicate with each other through the target communication gateway, so that the vehicle can realize functional iteration and upgrade, and users can subscribe to vehicle service functions according to their needs.

[0045] In an exemplary embodiment of the present disclosure, the first power distribution domain control module 21 is configured to supply power to the autonomous driving system; the actuators of the autonomous driving system may include a laser radar, a switch, a 5G network module, a vehicle-road cooperative on-board unit, etc. The electrical components in the cab may include, but are not limited to: a wiper motor, cab lights, a cigarette lighter, an air conditioner, a key, a handle, a data recorder, a navigation system, and an on-board T-BOX (Telematics BOX, also known as a telematics control unit). In an exemplary embodiment of the present disclosure, the first power distribution domain control module 21 is also configured to supply power to the steering system. The steering system can be arranged under the cab. The steering system is powered by the first power distribution domain control module 21, which is more conducive to the arrangement of the wiring harness in terms of physical location, and is conducive to further reducing the wiring harness of the entire vehicle.

[0046] Exemplarily, depending on the type of vehicle, the sensor signal of the chassis sensor is also different, and the pin information of the second power distribution domain control module 22 can be configured according to the needs of the vehicle. For example, the number of input pins of the second power distribution domain control module 22 is configured to match the number of input signals of the chassis sensor. Specifically, according to the number and type of input signals of the chassis sensor, the second power distribution domain control module 22 may include one or more second power distribution domain controllers, and according to the type and number of input signals of the chassis sensor, the number of digital switch quantities and the properties of the digital switch quantities, the number of analog quantities and the properties of the analog quantities in the second power distribution domain control module 22 are set accordingly.

[0047] For another example, depending on the type of vehicle, the chassis electrical components are also different, and the number of output pins of the second power distribution domain control module 22 is configured to match the number of loads connected to the second power distribution domain control module 22. Specifically, the number of output pins of each second power distribution domain controller is configured according to the number of chassis loads.

[0048] For example, for different vehicles, the number and type of actuators on their chassis may be different. For example, some vehicles are equipped with centralized lubrication systems and automatic switching systems for main and auxiliary fuel tanks, and vehicles in cold areas may be equipped with liquid heaters, which will cause the number and type of loads connected to the second power distribution domain control module 22 to change. Exemplarily, the output pins of each second power distribution domain controller include multiple configurable power supply pins. The output pins can be configured to normal power, power controlled by CAN messages, or power controlled by one or more input pin signals, etc., through the host computer, so as to meet the power supply requirements of chassis electrical components.

[0049] Exemplarily, the total power output of the second power distribution domain control module 22 is configured to match the total power of the load connected to the second power distribution domain control module 22. This ensures that the second power distribution domain control module 22 provides stable power to chassis electrical components.

[0050] At the same time, the input signal of the chassis sensor connected to the input pin of the second power distribution domain control module 22 and the state of the output pin of the second power distribution domain control module 22 can interact with the vehicle control unit, including but not limited to the vehicle controller 3, through the communication bus. Exemplarily, the second power distribution domain control module 22 can interact with the vehicle controller 3 through CAN communication.

[0051] In an exemplary embodiment of the present disclosure, chassis electrical components may include: vehicle lights, horns, fuel filters, dry cans, axle differential solenoid valves, electronic cooling fans, etc. The second power distribution domain control module 22 is configured to supply power to the electronic braking system. The actuators of the electronic braking system may include a service brake module, a power recovery module, a retarding module, an anti-lock brake module, an electronic parking brake module, etc. The second power distribution domain control module 22 is also configured to supply power to the power system. For example, for fuel vehicles, the second power distribution domain control module 22 is configured to supply power to the engine, transmission, dry can, fuel filter, water cold treasure, etc.; for extended-range vehicles and pure electric vehicles, the second power distribution domain control module 22 is configured to supply power to modules such as the range extender, motor controller, extended-range generator controller, thermal management system, electronic cooling fan, and battery management system.

[0052] In an exemplary embodiment of the present disclosure, the first power distribution domain control module 21 is independent of the power supply circuits of each power-consuming device. Each channel of the first power distribution domain control module 21 integrates complete protection and diagnostic functions, including voltage monitoring, current monitoring, overcurrent, overvoltage, short circuit protection functions and programmable automatic retry functions. At the same time, the first power distribution domain control module 21 can also dynamically adjust and optimize energy according to the instructions of the vehicle controller 3.

[0053] Since the first power distribution domain control module 21 supplies power to the electrical components in the cab, the electronic control unit can directly control the load without going through a relay, so that the first power distribution domain control module 21 can monitor each electrical device connected to it in real time, and can synchronize information to the vehicle controller 3, and the vehicle controller 3 can display vehicle information on the instrument and the unmanned driving background, which is convenient for vehicle inspection and maintenance. Since each electrical device is powered separately, when the power supply of any electrical device is abnormal, it will not affect the circuit of the whole vehicle, so the adaptability of the whole vehicle to faults can be improved, and the ability of the vehicle to maintain functional stability under harsh working conditions can be improved. Moreover, since each electrical device is powered separately, and the protection and control of the first power distribution domain control module 21 when supplying power to the electrical components in the cab are integrated, it is convenient to troubleshoot. For any power supply line that fails, a preset fault code can be reported, displayed on the vehicle instrument or reported to the unmanned driving background, which is convenient for maintenance personnel to inspect and troubleshoot faults.

[0054] Exemplarily, the second power distribution domain control module 22 is also independent of the power supply circuits of each electrical device. Each channel of the second power distribution domain control module 22 integrates complete protection and diagnostic functions, including voltage monitoring, current monitoring, overcurrent, overvoltage, short circuit protection functions and programmable automatic retry functions. At the same time, the second power distribution domain control module 22 can also dynamically adjust and optimize energy according to the instructions of the vehicle controller 3. For the beneficial effects of this exemplary embodiment, please refer to the description of the aforementioned exemplary embodiment, which will not be repeated here.

[0055] In an exemplary embodiment of the present disclosure, the electronic and electrical architecture of the vehicle includes an instrument module, and the vehicle controller 3 can obtain sensor signals and generate instrument display signals through the first power distribution domain control module 21 and the second power distribution domain control module 22. The instrument module is connected to the vehicle controller 3 through CAN communication, and the instrument module is used to receive the instrument display signal and display the corresponding instrument information.

[0056] refer to Figure 1 As shown, the instrument module can use a liquid crystal display as a display interface to display the vehicle's operating status, fault information, etc. in real time. The instrument module can display the required content through CAN communication, but does not participate in control. Specifically, in the related art, the instrument module is connected to an air pressure sensor, a vehicle speed sensor, etc., and the air pressure signal and vehicle speed signal are collected and displayed through the instrument module, and transmitted to the vehicle controller 3. In this exemplary embodiment, the instrument module is connected to the vehicle controller 3 through CAN communication. Even if the instrument module fails, it will not affect the operation of the vehicle, which is more friendly to unmanned driving.
