Passive entry passive start verification with two-factor authentication

A system, comprising:

• a processor;
• and
• a memory for storing executable instructions, the processor programmed to execute the instructions to:
• receive, from a passive key device carried by a user, a first gait of the user approaching a vehicle;
• determine, via a vehicle perception system onboard the vehicle, a second gait of the user;
• determine that the first gait is within an acceptable similarity measure range to the second gait;
• and
• authenticate a vehicle access signal responsive to determining that the first gait is within the acceptable similarity measure range to the second gait.

A non-transitory computer-readable storage medium in a vehicle controller, the computer-readable storage medium having instructions stored thereupon which, when executed by a processor, cause the processor to perform steps that authorize a vehicle access signal using two independent signal verifications:

• receive, from a device associated with a user, a first gait of the user approaching a vehicle;
• determine, via a vehicle perception system onboard the vehicle, a second gait of the user;
• determine that the first gait is similar, within an acceptable similarity measure threshold, to the second gait;
• and
• authenticate the vehicle access signal responsive to determining that first gait is similar, within the acceptable similarity measure threshold, to the second gait.
