 INTRODUCTION

The Government of India felt the need for a permanent agency to expedite the
publication of standards and development of test facilities in parallel when the
work on the preparation of the standards is going on, as the development of
improved safety critical parts can be undertaken only after the publication of the
standard and commissioning of test facilities. To this end, the erstwhile Ministry of
Surface Transport (MoST) has constituted a permanent Automotive Industry
Standards Committee (AISC) vide order No. RT-11028/11/97-MVL dated
September 15, 1997. The standards prepared by AISC will be approved by the
permanent CMVR Technical Standing Committee (CTSC). After approval, the
Automotive Research Association of India, (ARAI), Pune, being the secretariat of
the AIS Committee, will publish this standard.

Ministry of Road Transport took initiative to further increase vehicular safety with
the aim to reduce causes of accidents. Following was the focus while formulation
of this standard:

1. Enhancement in use of safety belts to improve safety

2. Accidents caused due to over speeding of vehicles.
3. Ease of occupant exit in case of electric power failure in a centrally locked
vehicle
4. Reduce possibilities of accidents (child over run) while parking in reverse
gear.
5. Driver airbag mandate as additional passive safety measure.

This standard specifies requirements of special features, which are in addition to

present mandatory requirements to mitigate above causes.

Reverse Park Alert Systems (RPAS) which uses object-detection devices (sensors)
or camera based displays in order to provide the driver with information about
obstacles in specified zone while reversing the vehicle The test objects in this
standard are defined based on systems using ultrasonic sensors and electro-
magnetic sensors which reflect the most commonly used technology. For other
sensing technologies possibly coming up in the future, these test objects shall be
checked and changed if required.

The AISC panel responsible for formulation of this standard is given in Annex 8.

The Automotive Industry Standards Committee (AISC) responsible for approval of

this standard is given in Annex 9.

c) Ambient wind speed: 5.4 m/s Max.
3.1.2 The test shall not be affected by reflected sounds from surrounding walls, auxiliary
test equipment or other objects.
3.2 Test object
The monitoring range capability of the RPAS shall be tested with the following test
objects:
a) Test object H for the horizontal test: plastic tube, grey, 75 mm diameter,
1000 mm length
b) Test object V for the vertical test: plastic tube, grey, 75 mm diameter, 300
mm length
The material of the tube for the test object may be different from the above
specification with agreement between manufacturer & test agency.
3.3 Test procedure
3.3.1 Operational tests for compliance to the specified monitoring range shall be
performed on a vehicle or on a test structure on which the installation conditions of
the RPAS of the selected vehicle model or model range (in fully laden condition) can
be reproduced.
3.3.2 Appropriate aids shall be used for identifying the test object positions.
3.3.3 A log shall be kept of the test positions where the object is detected and where the
object is not detected.
3.4 Test 1 – Horizontal monitoring range test
3.4.1 Position the test object H (1 m long) such that the axis of the tube is standing

Page 24 of 31
 perpendicular to the ground & at positions shown in the grid in Figure 2.
3.4.2 The number of measuring points in each row at 200 mm interval as shown in the
Figure 2 is indicative and will depend upon the actual width of the vehicle.
Referencing for the measuring point pattern shall be from the center of the vehicle.
3.4.3 If the distance from the outermost measuring point of the 200 mm grid to the outer
edge of the vehicle is more than 100 mm, an additional measuring point shall be
located there.
3.4.4 In the case of tippers, the 1.8 m monitoring range shall be measured from the face of
the sensor mounting. Any projections of the tipping superstructure behind the sensor
mounting surface shall be ignored.
3.4.5 The fraction obtained by dividing the number of points at which the test object is
detected by the total number of points at which it is placed shall be at least 0.9.
3.5 Test 2 - Vertical monitoring range test
3.5.1 Position the test object V (300 mm long) so that the axis of the tube is static &
parallel to the ground and its longitudinal center is at the grid measuring points
shown in Figures 3 & 4 as applicable.
3.5.2 The detection of test object V shall be checked at all indicated positions of the test
planes at 500 mm, 800 mm & 1100 mm, as applicable. (See Figure 5)
3.5.3 In case of vehicles where the frame height does not exceed 800 mm, the test at
1100 mm level shall not be performed and in case of vehicles where the frame height
exceeds 800 mm, the test at 500 mm level shall not be performed. Frame height shall
be measured upto the topmost point of the frame from ground.
3.5.4 Further RPAS fitted on Tippers need not provide any detection at 500 mm level (See
Figure 5)
3.5.5 Finally, the fraction obtained by dividing the number of points at which the test
object is detected by the total number of points at which it is expected to be detected
shall be at least 0.9.
