Ford Motor Company has applied for a patent on technology designed to deliver in-car advertisements by listening to conversations among vehicle occupants and analyzing historical location data, according to a recently published patent application.
The technology, described as “in-vehicle advertisement presentation,” would allow the system to monitor conversations within the car and detect keywords or phrases indicating the passengers’ destinations. For instance, if the system hears occupants discussing grocery shopping, it could serve ads related to nearby grocery stores along the route.
According to the patent, the system gathers information from various sources, such as the car’s location, speed, type of road, and traffic conditions, to further customize ads for the driver. The system may also predict future routes, speeds, and destinations based on previous trips. Additionally, it could pull from audio signals or historical user data to tailor the number and type of ads presented during the trip.
The patent notes that these ads would be delivered either visually or audibly through the vehicle’s human-machine interface (HMI), depending on the context. For example, if passengers are engaged in conversation, the system might prioritize visual ads to avoid disrupting the dialogue.
The patent describes these methods as maximizing “opportunity for ad-based monetization,” using vehicle destination prediction to deliver highly relevant advertisements.
Privacy Concerns and Ford’s Defense
The patent application, filed in February and made public on August 29, does not specify how the collected data would be safeguarded. It outlines the system as being primarily software-based, requiring no additional hardware in vehicles.
While the filing sparked concerns about privacy and the potential for intrusive data collection, Ford defended its decision to pursue the patent. In a statement, a Ford spokesperson emphasized that submitting patent applications is a routine business process, helping the company protect new ideas and build a robust intellectual property portfolio. Ford also stressed that patent filings should not be viewed as definitive indications of product plans, stating that it always puts customer interests first when developing new products and services.
In addition to pulling data from the car’s systems, the patent suggests the potential use of third-party applications to enhance ad customization. It could predict the number of ads a driver should receive based on their input preferences or the type of trip being made, whether it’s a long road trip or a visit to a medical facility.
Previous Controversial Patent Filings
This isn’t Ford’s first patent to raise eyebrows. In July, the company filed a patent for technology allowing cars to monitor nearby vehicles’ speed, capture photos, and send the data to law enforcement, a move that drew sharp criticism from privacy advocates. The patent remains under review by the U.S. Patent and Trademark Office.
Another controversial patent filed by Ford last year proposed a system enabling self-driving cars to repossess themselves if their owners were behind on payments. This technology would allow the car to lock its own steering wheel, brakes, and air conditioning, eventually driving itself to a repossession lot. Following a public backlash, Ford walked away from the application in October 2023.
As the third largest auto manufacturer in the U.S., Ford holds a significant share of the market, securing 12% of new vehicle registrations in 2023, according to Experian. However, these patent filings continue to prompt debate about privacy and consumer rights in the age of increasing technological integration within vehicles.
