In this paper. we consider the Homicidal Chauffeur (HC) problem as an interesting and practical differential game. At first. we introduce a bilevel optimal control problem (BOCP) and prove that a saddle point solution for this game exists if and only if this BOCP has an optimal solution in which the optimal value of the objective function is equal to $1$. https://fitnessgravesyardes.shop/product-category/kit/
