1. A driving support device for a vehicle, the driving support device comprising:
a processor configured to execute non-transitory program instructions stored in a memory to:
calculate a sensitivity index value for avoiding a target that is at risk of collision, based on a driving operation content of a driver of the vehicle;
determine a driving support method to be applied to the vehicle as support that is provided to control the distance in the lateral direction between the vehicle and the target when the vehicle passes the target, in a case where the sensitivity index value calculated by the processor is higher than a predetermined threshold, or as support that is provided to control the speed of the vehicle when the vehicle passes by the target in a case where the sensitivity index value is lower than the predetermined threshold; and
execute the support to control the distance in the lateral direction or the support to control the speed of the vehicle determined by the processor;
wherein the processor calculates the sensitivity index value of the driver based on a distance between the vehicle and the target in a front-rear direction, a sense of the driver regarding the distance in the front-rear direction, a distance between the vehicle and the target in a lateral direction, a sense of the driver regarding the distance in the lateral direction, a speed of the vehicle, a speed of the target, and a sense of the driver regarding the speed.
