The control unit is configured for selectively outputting an inflation signal and a deflation signal. The pneumatically inflatable protective cover is configured for being attached to a bumper of a vehicle and is normally in a deflated condition. The air pump is electrically connected to the control unit and is fluid communicatively connected to the protective cover. The air pump supplies compressed air to the protective cover for inflating the protective cover when the inflation signal is outputted by the control unit. The air pump facilitates deflation of the protective cover when the deflation signal is outputted by the control unit. ## Claims ### Claim 1 A vehicle bumper protection system comprising: a control unit configured for selectively outputting a first control signal and a second control signal;
