Systems and methods for hands-free liftgate activation

A method comprising:

• receiving a liftgate activation signal;
• receiving first data from a sensor of a vehicle at a first time and second data from the sensor at a second time;
• determining that a first difference between a second value associated with the second data and a first value associated with the first data is greater than a first threshold amount;
• disabling, based on the determination that the first difference is greater than the first threshold amount, activation of a liftgate of the vehicle;
• receiving third data from the sensor;
• determining that a second difference between a third value associated with the third data and the first value is less than a second threshold amount;
• and
• enabling, based on the determination that the second difference is less than the second threshold amount or a determination that a first timer has elapsed, activation of the liftgate.

A non-transitory computer-readable medium storing computer-executable instructions, that when executed by a processor, cause the processor to perform operations of:

• receiving a liftgate activation signal;
• receiving first data from a sensor of a vehicle at a first time and second data from the sensor at a second time;
• determining that a first difference between a second value associated with the second data and a first value associated with the first data is greater than a first threshold amount;
• disabling, based on the determination that the first difference is greater than the first threshold amount, activation of a liftgate of the vehicle;
• receiving third data from the sensor;
• determining that a second difference between a third value associated with the third data and the first value is less than a second threshold amount;
• and
• enabling, based on the determination that the second difference is less than the second threshold amount or a determination that a first timer has elapsed, activation of the liftgate.
