Problems solved by technology

Although the traditional electronic control braking system can implement braking through the electronic control system, since the electronic control system is only a loop of the braking system, once it fails, the driver can only rely on the driver to step on the brake pedal to achieve braking.

Embodiment Construction

[0031] The specific implementation manner of the patent of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032]An electronically controlled braking system for unmanned commercial vehicles, which is composed of a main ADV controller, a backup ADV controller, a main battery pack, a backup battery pack, a front dual-channel pressure control module, a rear dual-channel pressure control module, a brake gas Chamber, spring brake cylinder, ring gear and wheel speed sensor, gas pipeline for connection, wire harness, etc.

[0033] The two sets of ADV controllers in the present invention belong to the whole vehicle controller, which are responsible for judging whether to perform braking, whether to release the braking, and the magnitude of the braking intensity according to the vehicle state information transmitted by the environmental perception system, and through the CAN line to the front, The rear dual-channel pressure contr...

Abstract

The invention relates to an electronically controlled braking system with redundant functions, and discloses an electronically controlled braking system for unmanned commercial vehicles, which consists of a main ADV controller, a backup ADV controller, a main battery pack, a backup battery pack, Front dual-channel pressure control module, rear dual-channel pressure control module, brake chamber, spring brake cylinder, ring gear, wheel speed sensor, gas pipeline for connection, and wire harness; two sets of ADV controllers belong to the vehicle The controller is powered by an independent battery pack. The front and rear dual-channel pressure control modules are integrated with a controller chip module, four sets of two-position two-position normally closed solenoid valves, two sets of relay valves to speed up the response of the service brake, and two Group air pressure sensor. The invention can ensure that the vehicle will not exit the electronic control braking in the case of any single failure by adopting dual electronic control circuits, dual power supplies and dual CAN communication, effectively ensuring the braking safety of the unmanned vehicle, and can meet the requirements of L5 Level unmanned level of braking system requirements.

Description

technical field [0001] The invention relates to an electronically controlled brake system with redundant functions, in particular to an electronically controlled service brake system for unmanned commercial vehicles using a double-circuit air brake system. Background technique [0002] With the development of automobile technology, intelligence has become the development strategic goal of automobile manufacturers in various countries, and the ultimate goal of automobile intelligence is unmanned driving. On the one hand, the unmanned driving technology of commercial vehicles can solve the pressure of rapidly increasing labor costs, and on the other hand, it can also avoid traffic accidents caused by fatigue driving, especially in relatively closed places such as mines and ports. The application prospect is very broad. For unmanned commercial vehicles, it is particularly important to have a safe and reliable braking system. Although the traditional electronically controlled ...
