Toner

A driver assistance apparatus is configured to carry out processing including: detecting a moving body and surrounding environment around the vehicle; predicting driving actions of the moving body detected; calculating collision risks between the moving body and the vehicle after a predetermined period of time, for the respective driving actions predicted of the moving body, on the basis of distances between the moving body and the vehicle after the predetermined period of time and probabilities that the moving body takes the respective driving actions; and setting a driving condition of the vehicle that provides a smallest one of the collision risks.

Driver assistance apparatus and recording medium containing computer program

An object recognition apparatus includes at least one processor and at least one memory communicably coupled to the processor. The processor sets one or more object presence regions in each of which an object is likely to be present, on the basis of observation data of a distance sensor. The processor estimates an attribute of the object that is likely to be present in each of the one or more object presence regions. The processor sets, on the basis of the attribute of the object, a level of processing load to be spent on object recognition processing to be executed for each of the one or more object presence regions by using at least image data generated by an imaging device. The processor performs, for each of the one or more object presence regions, the object recognition processing corresponding to the set level of the processing load.
