Abstract
A collision warning apparatus in the form of a portable, housing removably 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 mounted within the housing without reliance on external signals, except for input power, from the host vehicle. The master controller activates visible and/or audible indicators on the housing to alert the driver of the collision threat level.
Claims10
A vehicle collision warning apparatus comprising:
- a portable housing removably mountable in a vehicle;
- the portable housing having only an electrical power connection to the vehicle as a sole external connection to the vehicle;
- a control mounted in the housing and coupled to a sensor mounted in the housing, 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 the 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, carried by the housing, 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 a vehicle.
