While checking functional correctness for automated driving is often achieved through vast amounts of automated and manual field testing, automating specification verification is essential for developing and releasing fully self-driving vehicles. This paper presents an automatic bounded model checking approach for functional specifications over longitudinal vehicle controller implementations. The proposed method checks the actual embedded program, rather than an extracted abstract model. The specification is converted into a monitor that is interleaved with the execution of the program over a finite time horizon in closed-loop simulation. A decomposition is proposed to tackle the verification complexity. This allows verifying the program for whole parameter sets using a software model checker as opposed to testing only individual samples. The approach is capable of identifying functional flaws in several exemplary longitudinal controllers with variable complexity.    «
