Abstract
A model for emergency reaction of a vehicle (or its driver) to an obstacle ahead helps us to understand, predict, and calculate. This paper suggests how alternative models can be constructed. the basis is specification of (1) a small number of states of the vehicle (e.g., normal driving, braking, stationary), (2) rules for transitioning between states, and (3) a dependent variable (e.g., impact speed). The rules will include one or more parameters that are characteristic of the vehicle (or driver), and which need to be estimated by testing. The models generated are intended for application in, for example, interpreting the results of testing a vehicle equipped with an AEB (autonomous emergency braking) system--in particular, in inferring what would happen in conditions (e.g., challenge distances and travelling speeds) that are not directly tested.
