• The Mini 1 car reversing aid is an automatic alert system that warns driver's of pontential obstacles while backing up their vehicle.
• The Miniature acoustic sensors transmit a modulated beam signal.
• This beam is capable of seeing through fog, rain, smoke, and snow..day or night.
• When the signal strikes a solid object directly, it bounces back to the receiver and instanteously transmits a signal to the microprocessor.
• The 8 bit microprocessor processes the feedback signals and calculates the vehicle distance to the obstacle.
• The device is only activated when the driver puts their vehicle into reverse.
• The system alerts the driver with a variable multi tone audio pulse.
• The audio pulse intensity increases and the audio tone changes as the vehicle comes closer to the obstacle.
• The voice distance module will SPEAK in a female voice at 8 feet, 5 feet, 3 feet and crash.
• It will also say object in blind area.
• Between these warnings, audible and different tones will indicate as you get close to a object.
• Detecting range 8 feet-12 inches. Small waterproof detection sensors designed to operate in all environments.
• Adhesive mount design eliminates drilling. All wire ties, special mounting tape, wire holders and instructions are supplied.
• Easy to install, 3 sensors mount on your bumper with telephone plugs to the module which snaps in.
• One speaker with 3.5 meters of cable, simply PLUGS into unit.
• No cutting or splicing required other than connecting the power wire to your reverse bulb and a ground. THATS IT!
• The 8-bit microprocessor programmed with ‘Intelligent Control Software’ incorporating ‘fuzzy logic’ processes the target signal to calculate distance or range, as well as the closing speed between the host vehicle and the obstacles in the path of the host vehicle. The processor automatically and continuously computes this information. If the processor determines that the existing conditions require the driver to take any precautionary or corrective action, special emergency sounds are generated.
• The micro series speaker can be mounted anywhere inside the passenger compartment of your vehicle. The system is activated when the driver puts their vehicle into reverse. The system alerts the driver with a variable multi-tone audio pulse. The audio pulse intensity increase and the audio tone changes as the vehicle back closer to an obstacle. In addition to the variable multi-tone audio pulse, the system alerts the driver with our advance VDI (voice distance indicator) module. The VDI module verbally tells the driver the vehicle-to obstacle distance in feet and inches.
