Vehicle driving assistance apparatus and method

摘要

A driving assistance apparatus assists turning operation of a vehicle at an intersection by taking critical variables into account. The apparatus first estimates friction coefficient of a road to determine a suitable acceleration in turning, and then calculates a required period of time to finish turning by using other variables such as a width of the road derived by one of the functions of the apparatus. Based on the comparison with the time that the oncoming vehicle in the opposite lane will take to arrive at the intersection and the required time for turning, driving assistance for the vehicle to turn safely at the intersection can be appropriately provided.
