Abstract
An automatic braking system for a vehicle is provided. This system includes generally a speed sensor for monitoring speed of the vehicle and a distance sensor for monitoring a distance between the vehicle and the preceding vehicle. The system determines a marginal time required for the vehicle to collide with the preceding vehicle based on speed relative to the preceding vehicle and the distance to the preceding vehicle to automatically actuate a brake when the marginal time is shorter than a preselected marginal time.
