Embodiment 1
[0051] Assuming that a high-speed train is running, the driver is told that an obstacle suddenly appears on the track 1km ahead, and it takes 30 seconds to remove the obstacle. The driver inputs these two pieces of information into the danger distance / processing time input unit, and at this time the current vehicle speed transmitted by the vehicle speed sensor to the central control MCU is 300km / h. The central control MCU immediately starts to run the internal orthogonal configuration optimization method, and its operation process is as follows: image 3 Shown as:
[0052] Step E1: The initialization module 32 starts to run, the number of segments of the braking process time is set to 20, and the initial guess value F of the braking strategy is set. (k) (t) is -0.5, with Both are 1, set the numerical calculation accuracy tol to 0.01, and set the number of iterations k to zero;
[0053] Step E2: Set the initial value of the ODE equations to x 1 (t 0 ) and x 2 (t 0 ), ...
