With increased car sharing, and autonomous vehicles around the corner, smarter vehicle diagnostics is quickly becoming a necessity. Loose Wheel Indicator is a software solution, combining the car’s existing sensors in a new, high-performance system.It requires no additional sensors whatsoever. Instead, it determines if a wheel – and which wheel – is loose only from the spectrum content of the wheel speed signals. This of course makes it very cost-efficient. Moreover, the system is robust against surface changes, load variations and different driving styles.
