The automotive industry continues to be a hotbed of innovation, with activity driven by, among other things, the safety of pedestrians or cyclists and the growing importance of technologies such as electrification, connected and autonomous. Acoustic vehicle signalling devices are mostly fitted in electric or hybrid vehicles or of the same types. In many countries, they are not just an option, but are required accessories for nearly silent electric vehicles to improve safety, as per government regulations. The innovation involves a wider approach for better road safety. In the last three years alone, there have been over 1.2 million patents filed and granted in the automotive industry, according to GlobalData’s report on Internet of Things in Automotive: Acoustic vehicle signalling devices. Buy the report here.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilising and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

290+ innovations will shape the automotive industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over 619,000 patents, there are 290+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, smart car seats, tyre sensors, and predictive maintenance systems are disruptive technologies that are in the early stages of application and should be tracked closely. Acoustic vehicle signalling devices, brake temperature monitoring, and autonomous parking are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are disc brake actuators and AI-assisted dimming, which are now well established in the industry.

Innovation S-curve for Internet of Things in the automotive industry

Acoustic vehicle signalling devices is a key innovation area in Internet of Things

The Acoustic Vehicle Alerting System (AVAS) duplicates the noise of a combustion engine in the lower speed range in order to warn other road users of an approaching vehicle.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 20+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of acoustic vehicle signalling devices.
