Abstract
Provided herein are systems and methods of alerting occupants in electric or other vehicles to assume manual control of vehicular functions. An environment sensing module can identify a condition to have an occupant within the vehicle assume manual control of a vehicular function. A chassis control module can control actuation of a suspension system, an acceleration system, a brake system, and a steering system. The chassis control module can have a normal mode and an escalation mode. The normal mode can reduce an external force feedback from outside the vehicle. The escalation mode can mechanically induce an internal force feedback from within the vehicle. A policy enforcement module can cause the chassis control module to change from the normal mode to the escalation mode to use one of a plurality of defined feedback patterns as the mechanically induced internal force feedback to convey the identified condition to the occupant.
