Latest Patents

Eriksson is associated with 1 patent, titled “Model-Based Road Estimation.” The patent describes a computer-implemented method for estimating the geometry of the road on which a vehicle is traveling. Its model-based approach can represent roads with varying numbers of lanes, including entrance lanes such as on-ramps and exit lanes such as off-ramps.

The disclosed method uses a Bayesian approach to track multiple lanes across different traffic scenarios, including highway driving. It estimates lane-center curves by combining vehicle-motion data, such as speed and angular velocity, with perception data from sources such as cameras, lidar, and radar. The perception data may identify lane markers, road edges, barriers, guardrails, other road markings, and other road users.

Career Highlights

Eriksson’s listed work at Zenseact AB connects his invention to the development of vehicle technologies. The patent’s focus on combining motion and perception data reflects an approach to estimating complex road geometry from multiple sources of information.
