EB’s software update over-the-air (OTA) solution

Update ECUs using over-the-air technology

Carmakers need to be able to update their software over-the-air (OTA) to guarantee security. A connected, but not updatable vehicle is a huge cybersecurity threat.

Aside from security, consumers are used to short innovation cycles like their smartphones and computers offer. They don’t expect to have to visit a car dealer or pop-in a cd to update vehicle software. That’s why over-the-air updates are becoming the method of choice for distributing everything from infotainment system updates to operating system security patches and system revisions or configuration changes.

With EB´s over-the-air (OTA) solution all this can be done through a secure connectivity gateway.

Benefits

Over-the-air updates save time

Delivering new features and applications wirelessly improves performance and enables fast fixes. Being able to add new features to the infotainment system or update navigation maps helps increase customer loyalty to your brand.
In well prepared environments, software copy operations can be done even while the consumer is driving, avoiding battery limitations. And this advanced scenario allows the flashing procedure to be done in a very short amount of time.

Reduce vehicle recalls and save money

Recalls can cost vehicle manufacturers billions of dollars. Using electronic control units (ECUs) to their full potential as software platform provides great competitive advantages, helping reduce recalls. The potential for savings on maintenance and warranty costs is tremendous.

Competitive advantage through faster time-to-market

The need for speed in automotive development in undeniable. Consumers want new innovations on a regular basis, even after they’ve bought a vehicle. Over-the-air updates make for more satisfied and loyal consumers.

New product offerings

Software is becoming a product in itself within the vehicle. With over-the-air updates, you can offer software to consumers not only at purchase time, but during the whole vehicle lifecycle. This opens additional revenue streams.
