The invention discloses a method and a system for determining a vehicle speed maximum value in a stake environment. The road control module sends a road working condition signal to the vehicle dynamics module, and sends a stake code signal, a stake radius signal, a stake X coordinate signal and a stake Y coordinate signal to the stake collision judgment module; the control module sends a control signal to the vehicle dynamics module and sends a brake control signal to the test bed module; the test bed module sends a wheel cylinder hydraulic signal to the vehicle dynamics module; the vehicle dynamics module sends a control signal to the test bench module, and sends a vehicle mass center X coordinate, a vehicle mass center Y coordinate, a vehicle geometric length, a vehicle geometric width and a vehicle mass center side slip angle signal to the stake collision judgment module; the stake collision judgment module sends a stake collision identifier, a collision stake code, a collision stake X coordinate signal and a collision stake Y coordinate signal to the vehicle speed iteration module; the maximum vehicle speed iteration module iterates the vehicle speed value in a loop mode.
