Intelligent Brake Systems for Electric Vehicles: Predictive Modelling and Control of Friction Brake Squeal Using Redundant Actuation Systems

Brake noise reduction, especially squeal, indirectly supports EU’s Euro 7 standard goals by minimising brake wear emissions. This project aims to enhance vehicle noise standards and address the amplified impact of brake squeal in electric vehicles, where the absence of engine noise makes brake-related sounds more prominent and disruptive. It investigates the fundamental mechanisms underlying brake-induced noise and vibrations (specifically squeal and judder), developing control mechanisms using a smart calliper system, including redundant actuation. The Leeds Brake Dynamometer facility will be used for validation. The impact of the developed techniques on vehicle performance and brake noise, will be tested under various driving conditions such as the WLTP standard brake test cycles.

<p style="margin-bottom:11px"><strong>Project Aims:</strong></p> <p>This PhD project aims to investigate and reduce the nonlinear vibration problem that led to brake squeal and judder. By developing modelling techniques, and control strategies, it will seek to:</p> <ul> <li>Identify the critical parameters influencing brake noise and vibration, with specific focus on squeal and judder.</li> <li>Develop predictive models to simulate brake behaviour under WLTP test conditions or similar driving cycles.</li> <li>Design new actuation mechanisms to control squeal and judder in real-time.</li> <li>Validate the proposed solutions through experimental test results using the Leeds Brake Dynamometer.</li> </ul> <p><strong>Potential Impact</strong></p> <p>In the short-term, this PhD research will yield advanced modelling and control methods to reduce brake noise and vibration, improving vehicle comfort and safety. Longer-term impacts include enhanced brake lifespan, supporting sustainable transportation through reduced brake wear and lower particulate emissions. The outcomes will be shared at various academic and industry events, such as the UK Automatic Control Council's (UKACC) PhD showcase, Euro Brakes conference, and will have feedback opportunities from partners such as Jaguar Land Rover. The interdisciplinary skills and insights gained will also have broader applications in nonlinear dynamics and control, benefiting a range of engineering fields.</p> <p><strong>External Partner</strong></p> <p>The applicants are seeking collaboration with industrial partners such as Jaguar Land Rover who will provide critical expertise in brake system design and EV performance. Such partnerships will strengthen the University’s industry ties, enabling practical applications and enhancing future research opportunities.</p>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
