Abstract: This disclosure is generally directed to systems and methods for detecting a water depth level using capacitive sensors. The systems and methods disclosed herein receive a first capacitive signal from a first capacitive sensor in a wheel well of an autonomous vehicle (AV) and determine that the first capacitive signal exceeds a threshold value. The AV controller may be configured to determine water levels using a capacitive sensor system, and perform mitigating actions that cause the vehicle to either clean soiled capacitive sensors, or move the vehicle to a location that mitigates the risk of vehicle damage. Other mitigating actions may be performed as well, including disabling or powering down critical vehicle components when the vehicle cannot be moved to another location, providing means for emergency vehicle exit, and sending warning messages to the fleet control server, to occupants of the AV, or to other emergency personnel.

Abstract: An algorithm for use with a restraint control module that controls a signal output to a vehicle fuel pump. The algorithm deploys a fuel cutoff signal when crash sensors sense a vehicle crash condition that meets or exceeds a fuel cutoff threshold employed by the algorithm. The fuel cutoff threshold is generally elliptical.

Abstract: A system and method for regulating the deployment of an airbag inflator in response to an out-of-position occupant is provided. An airbag tether is operatively associated with a tether position sensor which is itself operatively associated with a restraints control module (RCM) through an interface. Upon normal in-position deployment, the primary surface of the airbag cushion deploys car-rearward. In this event the tether acts on the tether position sensor at a normal time. If the airbag cushion contacts an out-of-position occupant, the expansion of the airbag cushion will be slowed and the tether will act on the tether position sensor at a later time. The resistor element signals the RCM of the slowed airbag expansion and, with this information, the RCM may decide to modify the deployment of the airbag by adjusting the inflator's second stage deployment time delay. The decision criteria for the deployment of the second inflator are thus time-based.

Abstract: A smart airbag (14) is monitored by a vehicle restraint control module (24) and includes a state sensor (42) that generates an airbag state signal. A smart airbag fault circuit (40) is coupled to the state sensor (42) and includes multiple state devices (50). Each of the state devices (50) has a characteristic that is indicative of the state of the smart airbag (14). The state devices (50) are configured to be monitored by the vehicle restraint control module (24). A smart airbag state monitor (44) is separate from the vehicle restraint control module (24), is coupled to the state devices (50), and alters the state in response to the airbag state signal.

Abstract: An apparatus in a mechanical returnless fuel system is provided that includes a fuel pump motor for providing fuel to a powertrain system. A powertrain control module provides an activation signal for activating the fuel pump motor. A restraint control system includes a restraint control module for providing a disabling signal for disabling the fuel pump motor in response to a vehicle impact. An electronic relay switch is adapted for coupling to the fuel pump motor to selectably energize the fuel pump motor according to a conductive state and a non-conductive state of the electronic relay switch. A relay controller packaged with the electronic relay switch is responsive to the activation signal and the disabling signal for selecting the conductive state according to the activation signal when the disabling signal is not present and selecting the nonconductive state when the disabling signal is present.
