In his paper [2], Urabe has given a method of a posteriori error estimation of approximate solutions for boundary value problems with nonlinear boundary conditions. In the present paper, the author applies Urabe's method to the boundary value problem with nonlinear boundary conditions derived, by means of the author's method [1],from two point boundary value problem concerning piecewise smooth systems in her previous paper [1], and she gives a method of a posteriori error estimation of approximate solutions to the two point boundary value problem in question.
