Electrical system for controller with distribution type architecture and power supply redundancy electric intelligent vehicle

Abstract

The invention relates to an electrical system for a controller with a distribution type architecture and a power supply redundancy electric intelligent vehicle. The electrical system comprises a power supply unit, a key switch (16), a whole vehicle controller unit, a line control power-assisted unit and a vehicle part controller which are mutually connected through a power supply line, wherein the power supply unit is composed of a main storage battery (12) and an auxiliary storage battery (11); the power supply line is composed of a main constant electric line, an auxiliary constant electric line, a main ACC line, an auxiliary ACC line, an ON line and a START line which are respectively connected with the key switch (16); the whole vehicle controller unit is composed of a whole vehicle controller (18) and a redundancy whole vehicle controller (20); the line control power-assisted unit is composed of a line control power-assisted device and a redundancy line control power-assisted machine; and the vehicle part controller is connected with the main ACC line and the auxiliary ACC line through a single-pole double-throw relay. Compared with the prior art, the electrical system solves the requirement of an electric intelligent vehicle for redundancy and improves the running safety of the vehicle.

Description

technical field [0001] The invention relates to an electrical system of an electric intelligent vehicle, in particular to a controller of a distributed architecture and an electrical system of an electric intelligent vehicle with redundant power supply. Background technique [0002] The existing research and development of electric smart vehicles is generally based on pure electric vehicles, and the corresponding electrical systems are also developed based on the electrical systems of pure electric vehicles. Currently commonly used in automobiles, the controller is combined with corresponding components, and the architecture in which different controllers are distributed in the vehicle network is a distributed architecture. Chinese patent CN102501770A describes a pure electric vehicle electrical system. The electrical system describes the working mode of the pure electric vehicle electrical system in detail, but does not design redundancy for the electric intelligent vehicle...

Problems solved by technology

Chinese patent CN102501770A describes a pure electric vehicle electrical system, which describes the working mode of the pure electric vehicle electrical system in detail, but does not make redundant designs for the electric intelligent vehicle control system and the wire control system

If the development is still based on the original pure electric vehicle electrical system, when there is a problem with the key controller, key components or power supply, it will bring safety hazards to the entire vehicle and passengers
