Control algorithm utilizing autonomous sensors for open on approach side doors

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that, when executed on the data processing hardware, cause the data processing hardware to perform operations, the operations comprising:
• detecting an authenticated device in a proximity zone of a vehicle, the proximity zone comprising one of a plurality of proximity zones that collectively cover a 360-degree area around an exterior of the vehicle;
• based on the proximity zone, activating a portion of a perception system corresponding to the proximity zone of the vehicle while maintaining other portions of the perception system in an inactive state;
• detecting, in user data captured by the portion of the perception system, a user in the proximity zone of the vehicle and approaching the vehicle;
• classifying, based on the user data, an identity of the user in the proximity zone of the vehicle;
• identifying a target door of the vehicle for the user based on the identity of the user;
• and
• instructing the target door of the vehicle to automatically open for the user when the user enters an approach zone within the proximity zone and adjacent to the target door.
