Abstract

The invention belongs to the field of automobile unmanned driving, and particularly relates to an unmanned vehicle braking system which comprises a service braking system and a parking braking system EPB. The service braking system comprises a hydraulic braking system and an electromagnetic braking system. The hydraulic braking system comprises a brake-by-wire power assisting system, a vehicle body stabilizing system ESC and a hydraulic brake actuator integrated in a hub motor. The brake-by-wire power assisting system comprises a brake fluid storage pot, a main cylinder, a push rod, a brake control system ECU and a brushless motor. The brake control system ECU controls the brushless motor to work to drive the push rod to work, and the push rod pushes the main cylinder to form required oil pressure, so that the whole vehicle hydraulic brake system is pushed to work. Electro-hydraulic coupling braking is achieved, electromagnetic braking of the motor is utilized to the maximum degree to meet the whole vehicle braking requirement, the vehicle body posture and the wheel cylinder pressure can be adjusted through the vehicle body stabilizing system ESC, and the safety and stability of vehicle running are improved.

Description

technical field [0001] The invention belongs to the field of unmanned driving of automobiles, and in particular relates to a braking system of an unmanned vehicle. Background technique [0002] As the future research direction of automobiles, unmanned driving has a profound impact on the automobile industry and even the transportation industry. The advent of driverless cars will liberate human hands, reduce the frequency of traffic accidents, and ensure people's safety. [0003] Automatic braking system is undoubtedly one of the important components of self-driving vehicles. Since automatic control is inseparable from electric energy and signal transmission, when the system unexpectedly loses power or the signal transmission is interrupted unexpectedly, the failure of the braking system will bring extremely serious consequences. At present, there is no standard for the braking system of unmanned vehicles, and there is an urgent need for a universal and safe braking system. ...
