The invention discloses a braking system of a star wheel train turnover unmanned vehicle and a control method of the braking system. The braking system comprises a motor pump, an energy accumulator, a service brake valve, a parking brake valve, a central rotary body, a service brake and a parking brake. The whole machine adopts an electro-hydraulic control braking mode to respectively realize driving braking and parking braking; the brake is mounted at a hub at the tail end of a transmission system, so that the problems of overhigh rotating speed of a motor shaft and insufficient braking force caused by heating of the brake during service braking in the existing scheme are solved, and the service braking safety is ensured; when the whole vehicle is parked, parking braking can be achieved through power failure, an external power source is not needed, and parking safety is guaranteed; an inverse proportion brake valve is adopted, in a certain parking time period, an energy accumulator continuously supplements p
