Post Need a digital cruise control speed display on Torque app.
on: February 23, 2022 (GMT)

I own a Tata Altroz XZ variant where I have cruise control working fine and good. But the issue is that cruise control speed is NOWHERE displayed in the instrument cluster. Yes it sounds as a Blunder by the company and yes the company also has agreed without shame that it has miserably failed to display a simple cruise control set speed in the instrument cluster. Therefore, my request to the developer is to add a digital display where we can extract the details of the cruise control set speed from the register values via the OBD2 scanner. I am pretty sure that the data is somewhere present in the car’s Body control unit and made available to the ODB2 sensor since I have the option to increase/decrease the cruise speed by 2 kmph ( I can feel the change in speed but can’t see it anywhere ), the change happens, but is nowhere displayed.
If you can add this feature in your next update, I would be very thankful since this one feature can resolve this blunder by Tata which is spread all across India. Soon, people from India will slowly start realising this blunder by Tata and this addition of the feature from your end will help us!
Kindly let me know if you need any further data/information such as photos of the instrument cluster, an elaborate explanation of the issue etc, and I will be pleased to provide the same. Do reach out at bhaskarsjois@gmail.com for the same.
By the way, a great app with a very good UI. I am even happy to assist you technically as well since I myself am a programmer.

Thanks!

1. Please don’t expect that Torque shows all the information from your control units automatically. If the car manufacturer doesn’t expose this information, then there is little that Torque app itself can do. BUT: You can put this information in Torque in form of external/custom PIDs! just find out how to get that information from your car’s control block, configure it as external PID – and you can see it in Torque.
2.

“I am pretty sure that the data is somewhere present in the car’s Body control unit and made available to the ODB2 sensor since I have the option to increase/decrease the cruise speed by 2 kmph ( I can feel the change in speed but can’t see it anywhere ), the change happens”

if the car’s control unit does cruise control, it doesn’t mean at all that this information is published by that unit.
As an example: I own Honda CR-V and have same problem – no active cruising speed indication. I have cables and tools from Honda (manufacturer) and have access to all blocks, that are available over OBD2 connector. But unfortunately there is no active speed indication at all – nowhere. The only info for c/c in my car is the c/c keypresses, flag for active cruising, and 10 last reasons of deactivating c/c. So- there is no connection between presense of any information un control units and publishing it over OBD.

Hi!

(just to be a spoilsport :-) – it’s in a DBC file for hondas and they’re usually pretty standardised between model-years so there’s a good chance it’ll work in yours :-))

(from a 2017 crv dbc file):
BO_ 804 CRUISE: 8 PCM
SG_ HUD_SPEED_KPH : 7|8@0+ (1,0) [0|255] “kph” EON
SG_ HUD_SPEED_MPH : 15|8@0+ (1,0) [0|255] “mph” EON
SG_ TRIP_FUEL_CONSUMED : 23|16@0+ (1,0) [0|255] “” EON
SG_ CRUISE_SPEED_PCM : 39|8@0+ (1,0) [0|255] “” EON

For the tata however, there appear to be little to no DBC files currently for it and the information is not likely to be readily available as a PID request (you might try asking tata for this info for their mode 22 PIDs or canbus info, but I suspect they may decline unless you manage to get past their frontline support and magically get to an engineering person)

It’s going to be a case of looking at the CANBUS frames in monitor mode, using TorqueScan (yay) and it’s CAN explorer function.

You’ll then be able to twiddle the speed setting for cruise (if it will let you do it whilst stationary), or use a rolling road (I must point out at this point that safety takes priority over doing anything!). when you change the setting you should see the can frame change (there may be several scores of frames to look at for this so it may take some time)

Once you’ve done that you can start making (or adapting) an existing DBC file to get at the values
