<p>Provided is a vehicle velocity control device for controlling the vehicle into a sufficient low-velocity state in the event of a battery running out. This vehicle velocity control device (1) is equipped with: a battery (B); a motor (M) for driving wheels (23) of the vehicle (10) to rotate; an inverter (21) that is connected to the battery (B) via electrical paths (101, 102), converts direct-current power from the battery (B) into alternating-current power, and supplies the alternating-current power to the motor (M); and relays (SMR1, SMR2) that are provided on the electric circuits. The vehicle velocity control device (1), which makes a first determination to determine whether the battery (B) is in an out-of-power state or not and turns the relays (SMR1, SMR2) off if the battery (B) is determined to be out of power as a result of the first determination, makes a second determination to determine whether the battery (B) is about to run out or not and controls the motor (M) such that the velocity (V) of the vehicle (10) reaches a vehicle velocity (V2) or lower at which the SMRs can be turned off if the battery (B) is determined to be about to run out as a result of the second determination.</p> |
