Abstract
This paper intends to explore and study how to reasonably layout design the sensor of the self-driving car, to ensure the safety of the self-driving car. At the same time, the design of the dual-bus and vehicle circuit distribution of the self-driving car is needed, and the circuit structure and data transmission difference between the self-driving car and the conventional car are clarified. Of course, it should also consider the reliability redundancy design of the car, such as the design of the dual controller, dual actuator and dual power system.
By consulting relevant literature, we can understand the working principle and structural composition of self-driving car, and study the feasibility of the project objectives. Learning and studying the principles and characteristics of related sensors (including cameras, radars) of the Context-Aware system, we design and optimize the optimal redundancy, and ensure that the self-driving car sensor arrangement can bring enough security. Understanding the working principle of CAN bus, we know the data communication mode between components, and divide the CAN network nodes in a targeted manner to optimize the node layout while ensuring normal data communication. To consult the relevant literature to understand the driving safety redundancy design of self-driving cars, and we develop a dual-controller, dual-actuator, dual-supply and dual-bus system design for self-driving cars to ensure that a car can still operate normally withfaults in some components and systems. On the basis of the above, we organize all the data, and use the drawing software to design the layout and draw the relevant drawings.
Through design analysis, this paper has a relatively systematic normative design on the overall layout of self-driving car, and has a solution to the redundant design of autonomous vehicles, which has certain practical significance.
Key Words：Redundant design; Vehicle circuit; Bus design; Context-Aware system.
