Additional field descriptors in MME file for active safety

[washausen]

Hello,

this is an initial proposal to add field descriptors to mme file to adopt the format for active safety.
I would like to find some common descriptors and start with these or some of these with an additional "." at the beginning as custom descriptors.

You can find list in the attached Excel file or in the code at the end of this post.

Please give feedback, comments and further ideas in reply to this post.

Hello

here is a revised draft for the additional field descriptors in MME file for active safety.
A list is in the attached Excel and in the table below.

MME-Attributes_for_active_Safety.xlsx

Code: Select all

Field descriptor		Data format	Remark	values (List with semicolon or example)
VUT striking point		string		percentage of the vehicles width which strikes the target without braking in test (Anprallpunkt) in % or ft 	0; 25; 50; 75; -2ft; 0ft; +2ft 
Test function side		string		test function side gives an information of the location oft he target (VUT, main line, blind spot, …) 	right; left 
Lat. vel. test object x 	float		lateral velocity of test object in m/s 	 
Nominal vel. test object X	float		Nominal velocity of test objet to determine validities	 
Overlap VUT to TV		string		Overlap of VUT and target vehicle in Percent 	-50; -75; 100; 75; 50; 10 
Lane marking function line	string		Documentation of lane marking on function side 	Any (comment: continuous  line marking of not specified lane marking or several lane markings); Bot Dots; Dashed; Solid; none (comment: no line marking); Undefined (comment: line marking available ins sections: interrupted marking or different marking in sections)
Lane marking secondary line	string		Documentation of lane marking on secondary  side	Any (comment: continuous  line marking of not specified lane marking or several lane markings); Bot Dots; Dashed; Solid; none (comment: no line marking); Undefined (comment: line marking available ins sections: interrupted marking or different marking in sections)
VUT distance eye to end		float		Distance from the end of the vehicle to the center of the driver's eye ellipse (e.g. 95% Percentile for CNCAP 2021)  in [m]	 
Environment day light		string		day light	day; night; streetlight
Road surface temperature	float		road surface temperature (in Kelvin)	 
Sky conditions			string		Himmel / Bewölkung	cloudless; slightly cloudy; cloudy; not visible (in German: wolkenlos; leicht bewoelkt; bewoelkt; nicht erkennbar)
Precipitation type 		string		description of precipitation	none; rain; snow; hail (in German: kein; Regen; Schnee; Hagel)
Precipitation intensity		string		intensity of precipitation type (in German: Niederschalgsintenität)	not relevant; low; medium; strong (in German: nicht relevant; niedrig; mittel; stark)
Weather obstruction		string		description of obstruction by weather	fog; smog; spray; none (in German: Nebel; Smog; Gischt; keine)
Weight of obstruction		string		intensity of weather obstruction	not relevant; low; medium; strong (in German: nicht relevant; niedrig; mittel; stark)
Wind speed			float		wind speed in m/s	 
Road conditions 		string		properties of road conditions od street or proving ground 	dry; wet; wet; snowy; icy; NOVALUE (in German: trocken; nass; feucht; schneebedeckt; vereist; NOVALUE)
VUT Shape Front			tuples		the count starts on front left side; If the number of tuples is odd, the middle one must lie on the centerline of the vehicle	(x1;y1) (x2;y2) (x3;y3) (x4;y4) (x5;y5) (x6;y6) (x7;y7)
VUT Shape Rear			tuples		the count starts on rear left side; If the number of tuples is odd, the middle one must lie on the centerline of the vehicle	(x1;y1) (x2;y2) (x3;y3) (x4;y4) (x5;y5) (x6;y6) (x7;y7)
Dimension of test object X	tuples		width and length as tuple	(width; length) in [m]
Position of the sun		tuples		Proposal for data type: string Data format: (α; β) with α° as angle to VUT main direction and β° as angle to proving ground	(α; β)
Glare angle			float		Glare angle in degrees	

Currently the proposal for VUT shape is:

Code: Select all

VUT Shape Front   (x1;y1) (x2;y2) (x3;y3) (x4;y4) (x5;y5) (x6;y6) (x7;y7)    the count starts on front left side; If the number of tuples is odd, the middle one must lie on the centerline of the vehicle;
VUT Shape Rear    (x1;y1) (x2;y2) (x3;y3) (x4;y4) (x5;y5) (x6;y6) (x7;y7)    the count starts on front left side; If the number of tuples is odd, the middle one must lie on the centerline of the vehicle

An alternative would be:

Code: Select all

VUT Shape Front X   x1; x2; x3; x4; x5; x6; x7    the count starts on front left side; If the number of tuples is odd, the middle one must be on the vehicle's center line; semicolon as seperator
VUT Shape Front Y   y1; y2; y3; y4; y5; y6; y7    the count starts on front left side; If the number of tuples is odd, the middle one must be on the vehicle's center line; semicolon as seperator
VUT Shape Rear X   x1; x2; x3; x4; x5; x6; x7    the count starts on front left side; If the number of tuples is odd, the middle one must be on the vehicle's center line; semicolon as seperator
VUT Shape Rear Y   y1; y2; y3; y4; y5; y6; y7    the count starts on front left side; If the number of tuples is odd, the middle one must be on the vehicle's center line; semicolon as seperator

But I like the idea of data type “tuples”: (x; y)
with x any y as float. This also fits for

Code: Select all

Dimension of test object X : (width; length)
Position of the sun: (a; b)

For the descriptive attributes, which particularly concern the VUT (Dimesnson, Eye-line,...), the storage in Object/<testnumber>_<testobject>.mmi according to ISO MME 2.1 would also be very interesting.

Please give feedback, comments and further ideas in reply to this post.

Hello,

please find attached an improved version of the attributes. I have incorporated the remarks from today's meeting and compared the attributes with the TB21 4.0.2.
In addition, an attribute for "Nominal lateral velocity of test object to determine validities" has been added.

MME-Attributes_for_active_Safety.xlsx

(18.2 KiB) Downloaded 227 times

The differeces are:

Code: Select all

Draft				TB 21
====================================================
.Nominal vel. test object X	Velocity test object 1 lon.
.Nom. lat.vel. test object X	Velocity test object 1 lat.
.VUT Shape Front		.Profile-X test object 1
				.Profile-Y test object 1

Probably are „test object x” should always be the ending of an test attribute for test objects.
The value type of tuples should be more readable for coordinates.
The shape is not neccessary for other test objects than VUT.

So I would like to stick to the suggestion from the forum.

Kind regards,
Martin Washausen

Dear colleagues,

as decided on the Task Force Meeting (2023-09-20) for the part of this topic that is related to
"Intended Velocity"

The intended velocity will be coded for each test object as:

Code: Select all

Nominal vel. test object X	
Nom. lat. vel. test object X	

like

Code: Select all

Nominal vel. test object 1  :	
Nom. lat. vel. test object 1:	

These descriptors are optional.
This will be added to RED A 2023.

Hello,

please find attached the current list of mme attributes

How are you about the idea to allow the use of “TOB” instead of “test object” in the attribute. Due to the restriction of 28 characters it is hard to find good attribute names.
This would also allow to add more common attributes to the test objects:

Code: Select all

.Striking point TOB X 
.Shape Front TOB X
.Overlap VUT to TOB X
.Position Offset TOB X

instead of

Code: Select all

.VUT striking point
.VUT Shape Front
Overlap VUT to TV

Please see also the discussion in https://iso-mme.org/forum/viewtopic.php?t=699 which could be useful for Euro NCAP.

Kind regards,
Martin
