1. A vehicle comprising:
- a frame;
a locomotion source supported to the frame for use in providing locomotion for the vehicle;
a passenger door supported to the frame for access to a portion of an interior of the vehicle, the passenger door having a locked condition for prohibiting the passenger door from opening and an unlocked condition for allowing the passenger door to open;
a wheel supported to the frame;
a seat supported to the frame;
a transmission supported to the frame for operatively connecting the locomotion source to the wheel, the transmission comprising;
a park condition for maintaining the wheel in a parked condition; and
,a moving condition;
an occupant detection system mounted to the frame for determining whether the seat adjacent the passenger door is occupied; and
,a passenger door unlocking system comprising;
a control unit mounted to the frame having an integrated circuit, the control unit for selectively unlocking the passenger door comprising;
an input for receiving a signal from the occupant detection system;
a logic unit for determining whether to send an unlock signal to the passenger door based upon the input; and
,an output for selectively sending the unlock signal to the passenger door when the transmission is changed from the moving condition to the park condition.

9. A method of operating a locking system for a vehicle, the vehicle comprising a transmission having a park condition and a moving condition, a door having a lock, and a seat positioned adjacent the at least one door, the method comprising the steps of:
-
detecting an occupancy condition of the seat; detecting the locked condition of the lock when the transmission is moved from the park condition; locking the door while the transmission is placed in the moving condition; and determining whether to unlock the lock when the transmission is moved back to the park condition based on the occupancy condition of the seat and the condition of the lock when the transmission was moved from the park condition. wherein an occupant detection system mounted to the frame detects the occupancy condition of the seat; and
,wherein a control unit having an integrated circuit mounted to the frame detects the locked condition of the lock and determines whether to unlock the lock. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A vehicle comprising:
-
a frame; a locomotion source supported to the frame for use in providing locomotion for the vehicle; a passenger door supported to the frame for access to a portion of an interior of the vehicle, the passenger door having a locked condition for prohibiting the passenger door from opening and an unlocked condition for allowing the passenger door to open; a wheel supported to the frame; a seat supported to the frame; a transmission supported to the frame for operatively connecting the locomotion source to the wheel, the transmission comprising; a park condition for maintaining the wheel in a parked condition; and
,a moving condition; and
,a passenger door unlocking system comprising; a control unit mounted to the frame and having an integrated circuit, the control unit for selectively unlocking the passenger door comprising; an input for receiving a signal from the passenger door identifying whether the passenger door is in the locked condition or the unlocked condition when the transmission is changed from the park condition to the moving condition; a logic unit for determining whether to send an unlock signal to the passenger door based upon the input; and
,an output for selectively sending the unlock signal to the passenger door when the transmission is changed from the moving condition to the park condition. - View Dependent Claims (18, 19, 20)
