An unmanned vehicle communication system

Abstract

The invention relates to an unmanned vehicle communication system, belongs to the technical field of unmanned driving, and solves the problems that an existing intelligent vehicle communication systemis weak in structural expandability and low in data transmission efficiency among modules. The system comprises an upper-layer communication system and a bottom-layer communication system, and the upper-layer communication system comprises data exchange equipment, an Ethernet CAN conversion module and a CAN1 network; Wherein the data exchange equipment receives environment and positioning information and sends the environment and positioning information to the industrial personal computer, and the industrial personal computer generates vehicle operation control quantity, converts the vehicleoperation control quantity into CAN signals through the Ethernet CAN conversion module and sends the CAN signals to the bottom communication system through the CAN1 network; The bottom communication system comprises a CAN2 network and a CAN3 network, and the vehicle control unit receives the vehicle operation control quantity through the CAN1 network and performs information interaction with the energy controller; The whole vehicle controller is communicated with the whole vehicle control bottom layer driving equipment through a CAN2 network; And the energy controller communicates with the energy control bottom layer driving equipment through a CAN3 network. The system is convenient for function expansion, high in data transmission rate and low in network load rate.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to an unmanned vehicle communication system. Background technique [0002] With the rapid development of modern science and technology, various high and new technologies are being rapidly applied to people's production practice. Among them, under the theme of intelligence and cleanliness, electric vehicles and unmanned vehicles are developing rapidly. At the same time, the vehicle platform based on wire-controlled electric drive has advantages in the technical realization of intelligent vehicles. The demand for vehicle intelligence puts forward higher requirements on the accuracy and timeliness of the vehicle communication system when transmitting a large amount of data. [0003] At present, the communication system of the intelligent vehicle platform is single, and the structure is not scalable, which cannot meet the efficient data transmission between the modules...
