The invention discloses a calculation method for vehicle self-adaptive cruise optimal control, and belongs to the field of vehicle self-adaptive cruise control. The demands for real-time performance and accuracy of cruise performance optimal control are enhanced; for the problem of vehicle self-adaptive cruise optimal control, the feasible interval of a command acceleration variable quantity at the current sampling moment is calculated on line, the optimal value of the command acceleration variable quantity at the current sampling moment is solved by introducing a golden section method, then the command acceleration value of a vehicle at the current sampling moment is obtained, and self-adaptive cruise optimal control with high real-time performance and accuracy is achieved. With the calculation method, it is unnecessary to calculate gradient information of a cruise performance function, understanding is simple, a few parameters are set, generality is high, and the demands for high real-time performance and a
