Calibrations: All about live data
Getting an ADAS job right will largely depend on if the technician is looking at the information coming out of the car
Published: 20 January, 2023
Live data ensures calibrations are done correctly, but what we are seeing is a growth in the collection of the data from vehicles, whether they are single or multi-site operations. The data is accessed via the SRS module and once it has been harvested it becomes an asset to the business. The reason it is an asset is simple. It is because the data helps the business reduce key-to-key times for calibrations, while also enabling them to identify systems that need calibrating after a collision.
An example of this is when a technician uses the live data from a vehicle on the workshop floor to see the forces put on the car pre-and-post-collision. Once this data is reviewed, it enables the technician to understand where the forces have gone through the car easily. The next stage of the process is for the technician to check and carry out specific calibrations such as the radar at the front of the vehicle alongside any calibrations that are required at the rear to complete the job.
Live data also provides the technician with a safety blanket to ensure that the areas of the vehicle that have been worked on are checked and calibrated correctly before the vehicle goes back on the road.
So, live data helps on the workshop floor, but there are also other potential uses for it by insurers, who would use the data differently from the way the technicians on the workshop floor use it. Insurers would want to read and review the live data straight away from the vehicle that had a collision. Once this has been done and based on what they have seen, they could potentially write off the vehicle there and then rather than having a vehicle assessment done. This would be a cost-saving measure for them as they would not have to pay out for any work done.
We know live data is here to stay because ADAS systems are becoming common place on the newer models of car that are coming off the production line. This means that it is important that the people reading and reviewing the live data have the necessary knowledge and training to understand what they are looking at and the ways the data can help them complete jobs more efficiently and benefit their business.
- Rising business energy costs: Running to stand still?
The rise in energy prices is an issue that is not just affecting homeowners it is also causing problems for garage businesses, including bodyshops. It is leading to owners having to think if they can afford to run the business due to the increasing cost of gas and electricity eating into the already tight margins the business runs on. However, it is not all doom and gloom. There are many ways businesses can deal with rising energy costs alongside some new trends designed to respond to this issue.
Tools
Tools are the life blood of a garage or bodyshop and a fair few of the tools used on jobs are powered by rechargeable batteries, which need to be charged regularly. With the charging, the cost of electricity during the day is significantly more expensive, so businesses should look to charge them overnight, which comes under off peak times, when the energy price is cheaper. However, businesses should be reminded to only charge tools at night as long as they do not pose a fire risk.
Conservation
Do not waste electricity. Most of the wastage comes from items not being switched off, so it is important to remind technicians on the workshop floor that when they are not in use they should be turned off. This is especially important to remember when closing in the evening.
Heaters used on the workshop floor to keep staff warm are comfort items to have but they are expensive to run. In addition, they do not work well when processes like welding require heavy ventilation. This means that the heat produced from them will be sucked out of the workshop before it has had a chance to warm anyone up.
Ramps such as a three-phase electric ramp are expensive pieces of kit and are a key cog in the workshop. These ramps use quite a bit of energy however, reducing their energy consumption is pretty simple. It is achieved by ensuring the ramp is correctly maintained and is regularly oiled and serviced. In addition, technicians on the workshop floor should ensure the right ramp is being used for the car that is being serviced.
Price increases?
To combat the rise in prices we are seeing businesses, no matter their size, increasing the prices of jobs that require a lot of energy such as re-spraying and heating ovens to ensure the job is not loss-making. The price increases that are being seen now are here to stay for the foreseeable future, and it is something that the customer will have to be made aware of.
Going green?
Another avenue businesses are going down to cut costs is the use of green parts. Green parts are made up of undamaged and reusable parts from end-of-life and written-off vehicles, which does bring costs down. But they can cause issues once installed. This is highlighted by the fact that the part might have an electric module in it that is programmed for a specific vehicle or chassis. This means that if it is installed on a new vehicle, there is the possibility it may stop the vehicle from starting and it can also be difficult to code, which adds time to the overall job.
- Certifying your future
The rate at which the modern car is developing to include new functions based on new technologies is exponential.
The car owner is often unaware of this, as they see only the ‘HMI’ (human machine interface) that allows them to select and control functions and along with many other electronically controlled ‘things’, the expectation is that ‘it just works’.
Two key elements are changing with today’s and tomorrow’s cars. Firstly, they are changing into more sophisticated, interactive electronic systems, which require high levels of software compliance. Frequently this can mean that the vehicle needs ‘updating’ which may apply to one system or the complete vehicle. Today this is increasingly conducted by using standardised interface (vehicle communication interfaces – VCI’s) and pass through programming by establishing a direct connection between the vehicle and the vehicle manufacturer’s website. This is now being used even at the level of replacing basic components, such as a battery or engine management system components.
Secondly, vehicles are increasingly being connected through telematics systems so that the car is becoming part of ‘the internet of things’. This allows remote communication with the vehicle to provide a range of new services to the vehicle owner, driver, or occupants. These broadly fall into two categories – consumer related services, such as internet radio stations, link to e-mails, finding the nearest free parking space and much more, or business related access to in-vehicle data to allow remote monitoring of the status of the vehicle for predictive maintenance, remote diagnostics, vehicle use, pay-as-you-drive insurance etc.
Increasing isolation
The in-vehicle E/E architecture is therefore not only increasingly complicated and inter-active, it is more vulnerable to incorrect repair processes. To ensure that this risk is minimised, the vehicle manufacturers are increasingly isolating any possible external connections from the in-vehicle communication buses and electronic control modules. Effectively, today’s 16 pin OBD connector will no longer be directly connected to the CAN Bus and in turn to the ECU(s) but will communicate via a secure in-vehicle gateway. There may also be a new standardised connection which becomes a local wireless connection in the workshop as well as having remote telematics connection, but in both cases, the access to in-vehicle data is no longer directly connected.
Why is this isolation and protection of the in-vehicle systems so critical? Apart from the obvious protection against any malicious attack, there is an increasing safety issue. Thinking longer term, what happens when semi-autonomous cars or fully autonomous cars come into your workshop?
The key question is how to conduct effective repairs on these vehicle systems. At first glance, it may be the basic servicing still needs to be done, but even this will become more difficult, with certain items already requiring electronic control or re-setting. As this develops into more sophisticated systems, the vehicle manufacturer may try and impose more control over who is doing what to ‘their’ vehicles, based on their claim that they have a lifetime responsibility of the functionality of the vehicle and therefore need to know who is doing what where and when. This may lead to an increasing requirement for independent operators to have some form of accreditation to ensure sufficient levels of technical competence before being allowed to work on a vehicle. However, there is also a strong argument in many European countries (the UK included) that this is a market forces issue and that it is the choice of the customer who they trust to repair their vehicle and it is the responsibility of the repairer to be adequately trained and equipped.
What’s coming?
Will this market forces attitude still continue when the autonomous vehicle systems are part of the intrinsic safety of the vehicle? This is increasingly becoming the case as these semi or fully autonomous systems take over more control of the vehicle and stop any driver control.
Certainly, anyone attempting any DIY repair will find it much more difficult to access the information or the tools/equipment needed to repair their vehicle, as this will be beyond the knowledge and economic reach of the ‘Sunday morning repairer’, but should DIY repairs even be allowed in the future?
This raises an interesting argument about who should be allowed to work on a vehicle as the correct repair procedures become increasingly critical. Of course, vehicle manufacturers will continue to have full access to the vehicle and it’s systems, which increasingly will be via remote (telematics) access. This may even compromise the access available to authorised repairers (main dealers), but is seen as a necessary requirement to ensure that the vehicle has been repaired correctly and that the in-vehicle software is still functioning correctly.
The counter argument is that this also provides unacceptable levels of control and monitoring of the complete independent aftermarket – so what could be a solution?
Controlling competition
No one is trying to say that safety and security are not important, but there must be a balance as independent operators will continue to need access to diagnostic, repair, service and maintenance information and continue to offer competitive services to the consumer. The European legislator must protect competition, but this may also come with appropriate controls and this may mean that tomorrow’s technicians will need to demonstrate certain levels of competence, together with an audit trail of the work which has been performed in the event of a vehicle malfunction.
Independent operators already need high levels of technical competence – necessary for the consumer and the effective operation of their own business, but in the future this may also mean a form of licensing or certification that is required by legislation. If this becomes necessary, then it has to be appropriate, reasonable and proportionate.
The alternative is that the vehicle manufacturer could become the only choice to diagnose, service and repair the vehicles of tomorrow. I am sure we all agree that it is not what we want or need, so it may be that the increasing technology of tomorrow’s vehicles is the reason that the industry should now embrace change to mirror other safety related industry sectors, such as Gas Safe or NICEIC – qualified, competent and registered. The future is changing and the aftermarket needs to change with it.
