Abstract: A method for evaluating a minimum braking distance of a vehicle, in particular a car. The method comprises the step of obtaining at least one image in a movement direction of the vehicle associated substantially with an actual location of vehicle. A first road type indication from the at least one image is determined by a trained neural network architecture. Second road type indication associated with the actual location of the car are obtained from a database and compared with the first road type indication. If the second road type indication supports the determined first road type indication, an adjustment parameter associated with one of the at least first and second road type indication is selected. If second road type indication does not support the determined first road type indication, a default adjustment parameter as adjustment parameter is selected. Finally, a minimum braking distance using the adjustment parameter is set.

Abstract: The present disclosure relates to a method performed by a luminance assessment system of a vehicle for monitoring of on-board vehicle image capturing device functionality compliance with a predeterminable requirement level. The luminance assessment system obtains at respective one or more time instants (t1, t2, t3), a first image and a second image. A first section of the first images and a second section of the second images respectively cover a primary region. A first luminance value of the first section and a second luminance value of the second section are measured. A luminance deviation is determined by comparing at least one of the first luminance values to at least one of the second luminance values. A determination is made that, when the luminance deviation exceeds a deviation threshold, the first image capturing device or the second image capturing device failed to function according to the requirement level.

Abstract: This document describes techniques and systems for crowd-sourced continuous update data collection for automotive applications. Each vehicle of a vehicle fleet may include a logging system, a data query daemon, and a user application. The logging system logs application metadata or sensor data for a host vehicle. The data query daemon receives data queries from a remote data query system and detects the requested data in the application metadata and/or the sensor data being logged. The user application may provide information related to the data query to the vehicle user and request permission to execute the data query. In this way, application providers for ADAS and AD systems may collect relevant data from an existing vehicle fleet to develop updated or new applications without incurring the recurring cost of expensive data collection campaigns.

Abstract: A method and apparatus for handling outstanding interconnect transactions between a master device and an interconnect component. For example, a transaction intervention module coupled to an interconnect component and a master device of the interconnect component. The transaction intervention module is arranged to receive an indication of a functional state of the master device. If the master device is indicated as being in a faulty functional state the transaction intervention module is further arranged to determine whether any interconnect transactions initiated by the master device with the interconnect component are outstanding. If it is determined that at least one interconnect transaction initiated by the master device is outstanding, the transaction intervention module is arranged to finalize the at least one outstanding interconnect transaction with the interconnect component.

Abstract: A system on a chip (SoC) and method of operation are described. A data processor has a processor data word size of p×octets and is configured to handle data items having a data item size which is a non-integer multiple of the processor data word size. A memory controller is configured to write or read data items to a memory as multiples of m×octets. Data can be sent between the data processor and the memory controller on a bus. A data protection code generator is configured to generate a data protection code for a data item generated by the data processor before transmitting the data item and the data protection code over the bus to the memory controller which writes at least one octet including at least a portion of the data item and at least a portion of the data protection code to an address. A data protection code checker is configured to receive a read data protection code and a read data item and to check the read data item for an error using the read data protection code.
