Abstract

The invention discloses a redundant braking system supporting complete automatic driving of a commercial vehicle, and belongs to the technical field of commercial vehicle automatic driving. The systemcomprises a main control module, a redundancy control module, a trailer control valve, an air cylinder I, an air reservoir II, an air cylinder III, a first power supply, a second power supply, a first CAN network, a second CAN network, a front axle left brake air chamber, a front axle right brake air chamber, a rear axle left driving air chamber, a rear axle right driving air chamber, a rear axleleft spring parking air chamber and a rear axle right spring parking air chamber, and each wheel of the front axle and the rear axle is respectively provided with two wheel speed sensors; and the main control module and the redundancy control module communicate through an internal CAN network. Safety redundancy is achieved in all aspects of vehicle perception, control and execution, the braking safety requirement of the full-automatic driving technology is met, and the redundant braking system can be widely applied to tractors, cargo trucks and passenger car types such as 4X2 and 6X4 in commercial vehicles.

Description

technical field [0001] The invention belongs to the technical field of automatic driving of commercial vehicles, and in particular relates to a redundant braking system supporting fully automatic driving of commercial vehicles. Background technique [0002] Fully autonomous driving, as the highest form of autonomous driving technology, can greatly improve road safety through the collaboration of sensor perception, 5G communication, artificial intelligence decision-making and other technologies. On the other hand, for commercial vehicles that focus on creating social value, autonomous driving technology can also save labor costs, improve fuel economy, and optimize social resources. Therefore, autonomous driving technology has ushered in a period of rapid development in recent years. As an important part of ensuring the safe driving of vehicles, the braking system of vehicles is an important prerequisite technology to ensure the development of automatic driving technology. ...
