Driverless vehicle braking system and driverless vehicle

Abstract

The embodiment of the present invention discloses an unmanned vehicle braking system and an unmanned vehicle, including: a first solenoid valve, a main controller, an EBS controller, an ADCU controller, a relay valve, an air storage tank and a first brake gas chamber; the first solenoid valve is connected to the air reservoir through the air circuit, the first solenoid valve is electrically coupled to the ADCU controller and the relay valve respectively, and the relay valve is connected to the first brake air chamber through the air circuit; the ADCU controller It is configured to control the first electromagnetic valve after receiving the EBS controller failure instruction sent by the main controller, so that the first electromagnetic valve controls the relay valve to transfer the air between the air reservoir and the first brake air chamber The road is connected to supply air to the first brake chamber, and the EBS controller failure instruction is generated when the main controller detects that the EBS controller is in an abnormal working state and / or the main controller receives the first fault instruction sent by the EBS controller. The embodiment of the invention improves the safety and stability of the braking system of the unmanned vehicle.

Description

technical field [0001] The embodiments of the present invention relate to the field of unmanned driving, and in particular to a braking system of an unmanned vehicle and an unmanned vehicle. Background technique [0002] One of the core concerns of unmanned vehicle driving technology is the safety performance of the braking system of unmanned vehicles. At present, the braking system of unmanned vehicles generally adopts the air control method, based on the EBS (Electronic BrakeSystems, electronically controlled braking system) controller, and at the same time through the ADCU (Automatic Driving Control Unit, automatic driving control unit) controller , air pump, brake signal sensor, relay valve, ABS (Ant-ilock Brake System, anti-lock brake system) solenoid valve and air storage tank constitute a complete electronic control and air control integrated braking system. The unmanned vehicle braking system based on the EBS controller improves the safety of the braking system, and...

AI Technical Summary

Problems solved by technology

[0003] However, it is found that there are at least the following problems in the prior art: by adding protection valve devices such as steady state valves, although the safety margin of the braking system of unmanned vehicles can be increased to a certain extent, the premise of realization is that the EBS controller In normal working condition, if the EBS controller fails, it will not be able to provide braking force for the braking system of the unmanned vehicle due to the failure of the braking system of the unmanned vehicle, which will affect the safety of the braking system of the unmanned vehicle and stability

The above shows that the safety and stability of the driverless vehicle braking system need to be improved
