Driving support device, driving support method, and driving support program

A driving support method comprising the steps of:

• obtaining an end point of a reference speed zone in which a host vehicle travels at a reference speed by controlling an adjustment amount of a drive source output of the host vehicle, without applying a preset correspondence relation regarding an accelerator pedal position and the adjustment amount of the drive source output of the host vehicle;
• and
• after the host vehicle passes the end point of the reference speed zone, changing the adjustment amount by a first degree of change if an actual adjustment amount and an adjustment amount corresponding to application of the correspondence relation with the accelerator pedal position do not coincide.

A computer-readable medium encoded with a driving support program for causing a computer to execute the functions of:

• obtaining an end point of a reference speed zone in which a host vehicle travels at a reference speed by controlling an adjustment amount of a drive source output of the host vehicle, without applying a preset correspondence relation regarding an accelerator pedal position and the adjustment amount of the drive source output of the host vehicle;
• and
• after the host vehicle passes the end point of the reference speed zone, changing the adjustment amount by a first degree of change if an actual adjustment amount and an adjustment amount corresponding to application of the correspondence relation with the accelerator pedal position do not coincide.
