RPAS OVERVIEW

Reverse Park Assist System is an aiding system, which will assist the driver in the reverse gear while

parking at a speed of less than 5 kmph.

On reversing the vehicle, system will detect the obstacle behind the vehicle within the sensing zone which

cannot be viewed by internal rear view mirror or the outside rear view mirrors. The system indicates the

driver with the distance and direction of the detected obstacle along with the alert sound , which is

proportional to the distance. As the distance becomes smaller, the interval between the beeps becomes

shorter.

RPAS system consists of

1. RPAS ECU located below the co-driver seat.

2. Four RPAS Sensors located in the rear bumper.

Working of the Functionality

Start the Engine and engage the gear in reverse. RPAS image will get displayed in the infotainment

system as shown below.

1 Bars in the zones will get OFF (syncs with the background color) according to obstacle direction (left,

right or center) and as per the distance

a. If obstacle is in between 100 to 120cm –Bar 4 in that direction will be switched OFF

b, If obstacle is in between 75 to 100cm –Bar 3 & 4 in that direction will be switched OFF

c.If obstacle is in between 50 to 75cm –Bar 2, 3 & 4 in that direction will be switched OFF

d.If obstacle is less than 50cm –All bars in that direction will be switched OFF

2.Distance indicator is to display the distance of the closest obstacle. It will display the distance in multiples

of 2cm, whichever is shortest. Distance indicator will display as STOP if any of the obstacle is less than

50cm from vehicle bumper

3.Along with the display, a beep sound will come from front speakers.Frequency of the beep will increase if

obstacle is coming closer (crossing each zones) and the sound will be continuous if any of the obstacle is

less than 50cm.
