1. A vehicle speed control device implemented using one or more hardware processors, the vehicle speed control device comprising:
an information acquisition section implemented using one or more of the one or more hardware processors and configured to acquire information on an AP opening rate representing an opening rate of an accelerator pedal which is to be operated to input a request for accelerating a vehicle;
a target driving force setting section implemented using one or more of the one or more hardware processors and configured to set an AP opening rate-target driving force characteristic representing a target driving force to be applied to the vehicle for at least the AP opening rate; and
a deceleration controller implemented using one or more of the one or more hardware processors and configured to perform deceleration control according to the AP opening rate-target driving force characteristic,
wherein the deceleration controller is further configured to, when a deceleration operation element provided in the vehicle is operated for deceleration in a state where pressing on the accelerator pedal has been released, change the AP opening rate-target driving force characteristic to a second AP opening rate-target driving force characteristic, the AP opening rate-target driving force characteristic before change being a first AP opening rate-target driving force characteristic,
wherein the second AP opening rate-target driving force characteristic represents, for a deceleration force to be applied due to the release of pressing on the accelerator pedal, a second deceleration force larger than a first deceleration force that is based on the first AP opening rate-target driving force characteristic, and
wherein the deceleration controller is further configured to terminate the deceleration control according to the second AP opening rate-target driving force characteristic when a target driving force that is based on a result of applying the AP opening rate to the second AP opening rate-target driving force characteristic has reached a target driving force that is to be applied at the release of pressing on the accelerator pedal according to the first AP opening rate-target driving force characteristic.
