LTA, please clarify whether ERP 2.0 OBU power consumption is too high??

[dontwastetime]

a fine not exceeding $2,000 or to imprisonment for a term not exceeding 12 months or to both.

Wah shorter by 3 months only compared to Fujian gang

My friend is just a lowly engineer and he's not even part of the program - he was just used as a guinea pig

I have not seen the specifics on how they plan to do distance charging, whether it's by the M or KM, but generally GPS is accurate to within 10 metres bah

Anyway, I am just guessing but the same route may yield different pricing if they really implement distance and traffic based pricing i.e. if the road is packed and virtual gantries come into play, we may end up paying more, hence taking a longer route may be cheaper

They could handle the distance accuracy issue through virtual check points. Since we cannot just suka suka go off-road, it is relatively simple to charge based on the “checkpoints” or gantries if you prefer the term.

If there's a difference or not being accurate, the whole system is not reliable from the start.

Not sure about their system but GPS on the whole has improved a lot but still there is a tolerance of +/- 10 metres bah

Could be - can't be a pure GPS-based system - there has to be some form of check points to recalibrate the system, especially should there be any blind spots etc

 

[Mystyque]

Just came to me, since ERP 2.0 cannot off one. If our car breakdown and is towed, do we still kenna charges along with tow truck?

 

[focus1974]

i have this feeling might explode when temperature feels like 40.....

wait for the kancheong spiders to install and test it out first.

by year end, if got problem, the kancheong spiders would have reflected that.

There are 2 grades in the GPS system.

Military grade is extremely precise.

Civilian grade is usually off slightly in terms of precision.

During any conflicts in the region, the US can adjust their gps to reduce the accuracy.

I have been experimenting with gps loggers for some time. Even when logging my daily route with no deviation, the milage can be different for every trip. Logging done on my hp, which with Assisted GPS, it should be able to get a satellite lock fast even on a cold startup.

Problem is sinkie pwn sinkie mentality, since they kena the ugly design, they keep quiet of the problems to pwn others for a good night sleep.

Yes. that would probably be a reasonable assumption. lol

United they fall.

‘OBU’s power draw is comparable to an in-car camera’: LTA clarifies misconceptions about ERP 2.0 unit​

The rollout of the On-Board Unit (OBU) for ERP 2.0 has led to some questions about the three-piece setup for motor vehicles, and whether the new components will cause a huge power drain.

Responding to AsiaOne, a spokesperson from the Land Transport Authority (LTA) has confirmed that "the power draw is comparable to that of an in-car camera".

Comprising a touchscreen display, processing unit and an antenna, the new OBU is a computing device that allows motorists to access essential ERP and gantry information, real-time traffic updates and road safety alerts, while also enabling seamless payment with Cepas cards.

The OBU is part of the government's efforts to replace the existing ERP system, which has been in use for over 25 years and is approaching the end of its operational lifespan.

At present, more than 18,000 vehicles have been fitted with the new unit since installations began last August.

What's the fuss about the OBU's placement?
Placing the processing unit under the glove compartment has raised eyebrows. Netizens pointed out that such placement could potentially cause inconvenience or safety issues for drivers.

In fact, early adopters of the OBU had also raised the same concerns.

In response to this feedback, LTA announced back in March that drivers will have the flexibility to choose where to put their processing unit. In May, LTA further pointed out that the processing unit can be placed in locations such as under the driver's footwell or at the front passenger's footwell, as long as it is "technically feasible".

Existing car owners will be able to choose the preferred location of their OBU during installation, while new car owners should ask about possible placements at an authorised dealer.

Another updated feature following early adopters' feedback is a button on the display unit, which allows motorists to temporarily deactivate the Cepas card for complimentary parking without the need to manually remove the card. This feature does not affect payments for ERP charges.

Single-piece OBU not feasible for cars due to heat​

Netizens observed that vehicles would have three components installed, whereas motorcycles would only have one unit.

For motorcycles, the single-piece OBU was feasible given the outdoor ambient conditions. Considering that temperatures inside an enclosed vehicle may soar higher than typical outdoor levels, placing the processing unit on the dashboard could lead to overheating, potentially affecting its reliability.

With these improvements, is the OBU now more user-friendly? Watch the video for a round-up of everything you need to know about the fuss behind the new OBU and how to get yours installed fuss-free.

[GreatPumpkin]

IIRC dash cams that are on 24/7 need their own power supply.
Did LTA elaborate whether the OBU will totally off when the car is off?
And this equipment we are talking about was conceived last decade.

draw comparable power as dash cam, bigger than dash cam yet cannot tahan same conditions as dash cam

 

[gilcrest]

For something to overheat, means the current draw must be substantial.

LTA please clarify how much is the power draw when the car is parked, how long can we leave our cars parked before the car battery becomes too weak to start the engine

Can LTA please quash the rumours that the OBU would suffer permanent damage if internal battery of OBU becomes flat

Chiu expect them to be open about technical data? Similar to asking how much reserves sinkieland has

 

[HelloEllo]

Does it come with a power off button to turn off?

 

[jack-320]

Force people to pump and pay more oil

government indirectly earns more

really forward thinking

 

[SuperGreenHorn]

What's wrong with disclosing the power consumption of a device that is drawing power 24/7?
How does that affects national security?

And this equipment we are talking about was conceived last decade.

Precisely! dash cams that are on 24/7 either have their own auxiliary (battery) power supply or they have software settings that would shutdown the cam if battery voltage falls below a preset level to ensure there is still enough charge in the battery to start the engine.

Does OBU have own power supply or draws from our car battery?
Does it have settings to ensure that it does not deep discharge our car battery until engine cannot be started?

Why reporter nvr ask one?

Exactly, they are not being upfront here

As for why the reporter never ask, they just report what is being said and job is done

Coming back to the OBU and potential power drain - who's going to be responsible when our car batteries prematurely die due to the OBU?

 

[carey]

Does it come with a power off button to turn off?

According to some folks, NO

And if for any reason that we switch it off, we apparently need to go down to LTA to pay to re-start it
