Case Study:

Research Into Driver Pedal Feel Preference

HORIBA MIRA’s client was keen to find out how their customers would react to a new form of braking technology: brake-by-wire. In order to achieve this a test group of ‘non-industry professionals’ was set up across a broad demographic to ensure that the findings would involve feedback from users of all ages, sexes and driving ability levels.

Before testing could be conducted HORIBA MIRA carried out ethical checks including psychological profiling and briefing sessions to ensure that the participants’ well-being was maintained at all times. HORIBA MIRA were also responsible for sourcing the test participants and establishing the necessary test criteria.

A technically advanced demonstrator car was created in order to carry out the research. The set-up allowed technicians to change pedal feel and braking characteristics whilst the vehicle was moving in order to see how users reacted ‘on-the-fly’ when driving around HORIBA MIRA’s proving ground.

HORIBA MIRA built a number of prototype parts for the demonstrator, including a bespoke control unit, hydraulic modules and an ECU - allowing brake feel to be altered up to speeds of 70mph.

After carrying out in-depth research involving the test’s participants, a strong set of results were obtained. This enabled HORIBA MIRA to provide the client with an informative insight into user preference - allowing the customer to optimise the design of their brake-by-wire control system and hardware on future models.

HORIBA MIRA’s industry leading brake capability and engineering expertise enabled the excellent set of results to be successfully obtained and advanced demonstrator created also performed well throughout the tests.

The success of the initial test led to further research work that was carried out at HORIBA MIRA’s Nuneaton headquarters - which looked into how drivers respond to braking system failure.
