Abstract

Automatic emergency braking systems combine a forward-looking sensor(s), driver alerts, and automatic vehicle braking. These systems are designed to reduce or prevent rear-end collisions in which the large truck strikes another vehicle (and, to a lesser extent, head-on collisions). The forward-looking sensor is used to detect a lead vehicle within a preset distance or time-to-collision. The system alerts the large-truck driver of the lead vehicle's proximity through haptic, audible, visual, or a combination of warnings. At this point, the driver maintains control of the vehicle and can decide to reduce speed and/or steer to avoid the lead vehicle. However, if the driver does not apply the brakes or steer away from the lead vehicle and the system detects that a crash is imminent (i.e., a crash will occur if the truck continues at the current rate of speed and headway), the automatic emergency braking system will assume active control of the truck's brakes to prevent or mitigate the imminent crash...
