[0028] See Fig. 1 and Fig. 3, an electronic and electrical architecture, comprising a functional electrical control device, i.e. a power distributor 6, embedded with a master control unit 1, a power supply, i.e. a battery 7, the master control unit 1, hybrid cables 22 and 23, a branch hybrid cable 24, a plurality of intelligent electrical terminal 321, 322 and 331, 332, 333. Among them, the master control unit 1 is embedded in the power distributor 6, the battery 7 is connected to the master control unit 1 in it through the power input end 61, and the master control unit 1 is connected to two hybrid cables, which are connected to the hybrid cable 22 through the terminal 62 and connected to the hybrid cable 23 through the terminal 63.

[0029] The three external connection terminals 610, 620 and 630 of the power distributor 6 provide three power supplies for the outside.

[0030] Among them, the hybrid cables 22 and 23 contain power supply buses L1 for transmitting power and communication buses L2 and L3 for multiplex communication, and the power supply buses and communication buses are integrally formed by one-time injection molding (Fig. 2).

[0031] The intelligent electrical terminal 321 and 322 are connected to the hybrid cable 22, and the intelligent electrical terminal 331, 332 and 333 are connected to the hybrid cable 23. Among them, the intelligent electrical terminal 333 is connected to the hybrid cable 23 through the branch hybrid cable 24 and the branch terminal 234.

[0032] The hybrid cable 24 contains the same electrical wires as the hybrid cables 22 and 23, i.e. contains power supply buses and communication buses, but the form is not necessarily the same, i.e. the hybrid cable 24 is an integrally formed cable structure by one-time injection molding (as shown in Fig. 2), or it can be a small wire bundle after the power supply buses and communication buses are separately injection molded.

[0033] Among them, the intelligent electrical terminal 321 and 322 are connected to the hybrid cable 22 in the form of quick connector, and the intelligent electrical terminal 331 and 332 are connected to the hybrid cable 23 in the form of quick connector. The physical properties of the electrical wires contained in the hybrid cables 22 and 23 after connecting the intelligent electrical terminal do not change, i.e. the physical structure and form of the power supply buses and communication buses contained in the hybrid cables do not change after the intelligent electrical terminal is connected by quick connector.

[0034] The distribution of intelligent electrical terminals on the vehicle body is planned and designed according to the position and nature of the vehicle body electrical appliances, and meets the principle of accessing local electrical appliances nearby.

[0035] The intelligent electric appliance terminal connects the electric appliances in the specific area of the vehicle, including electric appliances (such as horn, lamp, motor), sensors (such as temperature, oil quantity, Hall angle), switches (such as high side, low side level signal, temperature alarm threshold signal) and bus control unit nodes (such as ultrasonic position sensing control unit connected by LIN bus) and the like.

[0036] The connection of the intelligent electric appliance terminals 321, 322, 331, 332 and 333, the hybrid cables 22 and 23 and the master control unit 1 forms an area control network system, which is controlled according to the set logic, and thus constitutes an electronic and electrical architecture of the application.
