Summary of the patent applications from Bayerische Motoren Werke Aktiengesellschaft on November 30th, 2023

Bayerische Motoren Werke Aktiengesellschaft (BMW) has recently filed several patents related to various aspects of vehicle technology. These patents cover areas such as battery cell design, data provenance in data processing chains, map data determination, and internal combustion engine design.

In terms of battery cell design, BMW has developed a battery cell with multiple electrode units housed together. Each electrode unit has a protective film consisting of an inner layer and an outer layer. The outer layer has a higher melting point compared to the inner layer, providing enhanced protection for the electrode unit.

In the field of data processing, BMW has focused on ensuring transparency of data provenance in a data processing chain. The patent application describes methods, systems, and devices for maintaining transparency and traceability of data throughout the processing chain. Each processing component is assigned a globally unique data identifier, and result data, including the identifier and information about the source data, is transmitted to a data manager.

BMW has also developed a device for determining map data for a specific route portion. This device acquires two sets of observations during separate trips along the route portion and calculates a measure of similarity for each possible pair of observations. Based on the measure of similarity, the device determines one-to-one associations between observations from the two sets, allowing for accurate determination of map data for the route portion.

In the field of internal combustion engine design, BMW has developed an engine design that includes a combustion chamber, an injector, a pre-chamber, and two spark plugs. The pre-chamber, injector, and second spark plug are arranged in a specific order in a plane perpendicular to the cylinder's axial direction, optimizing the combustion process.

Notable patent applications from BMW include a system for detecting a bypass lane at a junction with a traffic light system and adjusting automated longitudinal guidance functions of a vehicle based on this detection. Another application focuses on a vehicle control system that automatically controls the speed of a vehicle based on the distance to a signaling unit ahead. Additionally, BMW has filed patents for a vehicle guidance system that can automatically control the vehicle's movement in relation to a preceding vehicle and an intersection, and a system that determines when a vehicle is starting to drive off and decides whether to continue with automated longitudinal guidance based on certain conditions.
