DRIVE ASSIST DEVICE, AND DRIVE ASSIST METHOD

摘要

According to an embodiment, there is provided a drive assist device including an index calculation unit configured to calculate an index relating to a relative relationship between a vehicle and a target object and a drive assist determination unit configured to determine whether to execute a drive assist control of the vehicle based on the index and as the vehicle width direction component of the relative speed between the vehicle and the target object decreases, the index calculation unit calculates the index with increasing a degree of influence of the relative relationship relating to the vehicle width direction component, or as the vehicle width direction component of the relative distance between the vehicle and the target object increases, the index calculation unit calculates the index with increasing the degree of influence of the relative relationship relating to the vehicle width direction component.

主权项

1. A drive assist device comprising:
an index calculation unit configured to calculate an index relating to a relative relationship between a vehicle and a target object; and a drive assist determination unit configured to determine whether to execute a drive assist control of the vehicle based on the index, wherein, as a vehicle width direction component of a relative speed between the vehicle and the target object decreases, the index calculation unit calculates the index with increasing a degree of influence of the relative relationship relating to the vehicle width direction component among the relative relationships between the vehicle and the target object, or as a vehicle width direction component of a relative distance between the vehicle and the target object increases, the index calculation unit calculates the index with increasing the degree of influence of the relative relationship relating to the vehicle width direction component among the relative relationships between the vehicle and the target object.
