Abstract

Vehicles fitted with collision protection such as air bags, self locking safety belts etc. require sufficient warning of impending collisions. The invention provides a protective electro magnetic field around the vehicle with detectors spaced around the outside of the body. The presence of other vehicles is readily detected and the relative approach speeds calculated. The safety systems are activated if a threshold speed is exceeded. The extend of the protective field can be automatically increased with vehicle speed. A microwave, or radar system could also be used.
