The operation of the reversing radar:

The reversing radar engages when you put the reverse of your Peugeot 207. This one will ring as soon as you are close to an item behind your car. Generally intensity The signal will increase as the distance gets shorter so as to intensify the alert. In this way, the sound signal starts on average at 1 m from your vehicle and will become continuous at 5 cm.

It works using sensors, on average 4, arranged on the rear bumper of your car. Note that generally the sensors must be located at a height of 50 cm from the ground on the bumper, to be able to measure the right distance to ring. These sensors will calculate the purchase between your car and an exterior element, such as a wall or another car. In order to calculate this the catches send ultrasonic (ultrasonic waves) and when they reach the outer element will return an echo. Sensors will time the reception time of the ultrasound echo in order to calculate the purchase . Then they will send this data to a electronic control unit through electrical connections. The control unit will receive the data and send an audible signal to the driver to help them examine the distance left behind the vehicle. Please note, a reversing camera should not replace checking the mirrors.
