The invention relates to the technical field of automobile emergency braking, in particular to an unmanned vehicle emergency braking device. The device comprises a parking air cavity, a parking air source, a parking control valve and a standby parking control mechanism. An air inlet of the parking control valve is connected with the parking air source, an air outlet of the parking control valve is connected with the parking air cavity, and the air inlet is connected with a control air port in an on-off mode; and the control air port is configured in the mode that when set pressure is kept, the air outlet is disconnected with the exhaust port, and the air inlet is communicated with the air outlet, so that the pressure in the parking air cavity is kept; during pressure relief, the air outlet is communicated with the exhaust port so as to exhaust air in the parking air cavity; and the standby parking control mechanism is connected with the control air port and used for enabling the control air port to keep the set pressure or relieve pressure according to the control signal so as to control the pressure in the parking air cavity, and emergency parking is achieved. The problems that in the prior art, when an ADCU fails suddenly or is powered off, an EBS and an EPB brake system do not work and cannot be stopped, and safety accidents are likely to happen can be solved.
Description
technical field [0001] The invention relates to the technical field of emergency braking of automobiles, in particular to an emergency braking device for unmanned vehicles. Background technique [0002] In order to meet the driving safety requirements of ordinary commercial vehicles, two sets of independent parking devices, the driving brake and the parking brake, are designed. The driving brake is controlled by the electronic braking system (hereinafter referred to as EBS), and the parking brake is controlled by the electronic parking system. These two systems are directly controlled by the driver. When a car in normal condition needs to brake during driving, the driver steps on the foot brake, and the service brake system starts to work, resulting in braking. The vehicle decelerates; if a special situation occurs, emergency braking is required and the electronic control part of the EBS system fails, the driver depresses the brake pedal, and the mechanical part of the EBS s...
