Driving force

Viewed from above, one could certainly get the impression that MIRA primarily focuses on car-testing. The automotive engineering specialist’s Nuneaton HQ features 760 acres of impressive high-speed banked tracks and giant sheds that hide its advanced aerodynamic wind tunnels and crash labs.

In fact, vehicle testing — although extensive — counts for less than half of what MIRA does as an organisation. The majority of its work is focused on research and innovation. Co-ordinating this crucial aspect of MIRA’s work is Dr Anthony Baxendale, who has been the organisation’s head of research for the past three years. Whether as part of a collaborative project or internally funded, MIRA is involved in up to 15 research projects every year.

Having celebrated its 60th anniversary last year, MIRA, originally known as the motor industry research association, was set up to pool the research resources of all the major automotive companies in one place. Once a recipient of a government grant, it is now a fully commercial business that divides its work between testing operations and product engineering. ‘Some companies compete with us in certain areas but no one can match what we do in breadth,’ said Baxendale.

One of MIRA’s key innovations is its cutting-edge simulation work that is designed to reduce the amount of physical testing that is required during the design process of a new vehicle. Dubbed its ‘hybrid’ approach, MIRA uses a combination of physical testing of components in its facilities and a series of powerful software packages to accurately model early vehicle prototypes.

As well as working on behalf of its automotive customers — a client base that covers almost every international car manufacturer — MIRA also spends the majority of its surplus on research projects where the company itself is the customer. In conjunction with academia, this is where much of the exciting technology is to be found, said Baxendale.

With Leicester University, MIRA is developing advanced ‘pattern’-based software to run in-car electronics. On the hardware side, reliability is key. ‘In the not-too-distant future all safety-critical aspects of vehicles will be entirely run by the electronics. From active safety systems to advanced cruise control we are gradually moving towards the greater control of functions by software and hardware.’

To this end, MIRA is working with Loughborough University to develop extremely reliable, fault-tolerant microprocessors that can be trusted to work safely in a car. ‘You need to engineer into a car the same level of reliability as you get in an Airbus,’ he said. ‘But it is a completely different approach because while you can afford to spend £1m on a computer system for a plane that is obviously impossible in a car.’

As part of a major project part-funded by the Energy Savings Trust, MIRA is also using its considerable expertise to design an advanced hybrid 4x4 vehicle. Described by Baxendale as the ‘next generation’ of hybrid electric vehicle, the car — code-named H4V — will boast impressive fuel economy figures.

‘We hope it will reach 80 miles per gallon. We are looking at features like electric motors inside wheels and electric braking — all things that aren’t currently legal on UK roads due to safety issues,’ said Baxendale. ‘The clever bit is the strategy it will use when it’s in electric mode by being able to adapt to the style of driver, making it more intelligent.’

Due to be completed in just over a year’s time the H4V demonstrator is an indication of where MIRA’s priorities lie away from the day-to-day vehicle testing work. In fact, according to Baxendale, intelligent transport systems (ITS) are a key area of the association’s future strategy.

As well as his day job as head of research, Baxendale also sits as director of Innovits, a UK centre of excellence in telematics and ITS. Set up by the DTI, Innovitsis designed to help the UK exploit future opportunities in this exciting new area of transport technology and MIRA is taking the lead.

Last year MIRA ran a full-scale demonstration with a fleet of intelligent ITS-enabled vehicles on a section of UK road. It showcased the full range of ITS possibilities from automatic speed limiting and braking to speeding drivers receiving a slap on the wrist via vibrations through the accelerator pedal.

While MIRA developed the ITS for the project an important role was played by Leeds Universitywhich looked at driver behaviour when using ITS technology. Baxendale suggested that it is the public’s reaction to such perceived ‘Big Brother’ tactics that will determine how quickly these ‘active safety’ technologies are taken up. ‘Speed control isn’t something that will go down well with the public. It is not ready yet but attitudes are changing.’
