PORTABLE COLLISION WARNING APPARATUS

摘要

A collision warning apparatus, mountable in a vehicle to detect collision threat levels between the host vehicle and an object or target detected forward of the host vehicle. All processing and signal generation takes place in a controller in the housing without reliance on external signals, except for input power, from the host vehicle. The controller activates visible and/or audible indicators on the housing to alert the driver of the collision threat level.

1. A vehicle collision warning apparatus comprising:
a control coupled to a sensor, both the control and the sensor mountable in a vehicle, the sensor generating at least a center sensor beam to detect an object external of the vehicle; and the control, responsive to signals solely from the sensor, determining vehicle ground speed through side lobes of the center sensor beam reflecting off a road payment, determining the distance and the relative speed between the vehicle and a detected object external of the vehicle, and activating at least one of a visual and audible indicator indicating the potential for a collision between the vehicle and the detected object based on the vehicle speed and the distance and the relative speed between the vehicle and a detected object external of the vehicle.
