ABSTRACT:
A laser transmitter is configured to transmit a laser beam at an object, and a laser receiver is configured to receive a reflection of the laser beam. A speed sensor is connected to a vehicle speedometer system and receives vehicle speed information from the vehicle speedometer system. A processing unit receives laser pulse data from the laser receiver and road condition data from a road condition switch, and the vehicle speed information from the speed sensor. The processing unit calculates a relative speed of the object with respect to the vehicle, a distance from the object to the vehicle, and a relative acceleration of the object with respect to the vehicle. The processing unit further calculates a safe following distance based on the road condition data and the vehicle speed information, and compares the safe following distance to the actual distance from the object to the vehicle. The processing unit further calculates a collision time based on the relative speed of the object, the distance from the object to the vehicle, and the relative acceleration of the object. The collision time is displayed on a collision time display. A linear light display indicates the relative level of safety or danger based on following distance and collision time.
