Abstract:
A hands-free vehicle door opener utilizes a spring-loaded mechanical pushing device, or other method, to open a vehicle door a few inches upon a laser emitting device sensing a foot in its emitted laser. The laser is emitted from the laser emitter upon the key fob of a smart key being validated by the vehicle's smart key validation system when a user approaches the vehicle with the smart key fob. When the laser beam is interrupted, a signal is sent from a smart ECU to a door lock ECU, which unlocks the vehicle door. Next, a signal is sent to a door open ECU to unlatch the vehicle door. Upon door unlatching, the spring-loaded pushing device pushes open the vehicle door. Instead of a laser emitting device being used as the sensor, a device with electrical contacts, an ultrasonic wave emitting sensing device, or other device could be used.
