Abstract
A method for determining the time to collision between a host vehicle and an oncoming target vehicle, and for determining the necessary host vehicle deceleration for bringing the host vehicle to a standstill at the moment of collision. The method furthermore comprises the steps: determining the position (p) of the host vehicle as a function of time; determining the position (p) of the target vehicle as a function of time; for the moment of collision, as a first condition, setting the position (p) of the host vehicle equal to the position (p) of the target vehicle, and, as a second condition, setting the velocity (v) of the host vehicle to zero; using the positions and the conditions above to solve for the time to collision and the necessary host vehicle deceleration; and choosing the solution for time to collision that is positive and has the largest value.
