Abstract: Monitoring for thermal events in a vehicle may be provided while the vehicle is in a sleep mode. The monitoring may be performed by periodically switching one of several processing cores of an electrical control unit (ECU) of the vehicle to a run or wake state to obtain and analyze sensor data. A duty cycle for the periodic wakeups of the one of the several processing cores may be determined based on a balancing of an amount of time for sensing and analyzing the sensor data, a time corresponding to a characteristic feature of a thermal event, and/or a power constraint associated with the sleep mode of the vehicle.

Abstract: An electronic fuse is configured to sense a measured current through the electronic fuse and calculate a summation based on an amount of the measured current over time. The electronic fuse evaluates the summation with respect to an area defined according to a current squared with respect to time (I2t) plot for a wire specification. The electronic fuse shuts off current through the electronic fuse if the summation exceeds the area. The electronic fuse may control the flow of current to a device through a wire according to the wire specification. The electronic fuse may be part of a vehicle, such as a battery electric vehicle.

Abstract: A vehicle may include an east electronic control unit (ECU), a west ECU, or a third ECU. The first ECU may operate first components on a first side of a longitudinal axis of the vehicle, while the second ECU may operate second components on a second side of the longitudinal axis. The longitudinal axis may be defined as an imaginary line running from the front of the vehicle to the rear along its center, dividing the vehicle into the first and second sides. The third ECU may be positioned at the rear of the vehicle.

Abstract: Methods, systems, and apparatuses for jumpstarting an electric vehicle may include an electronic control unit (ECU) accepting external power connected to an externally accessible location of the vehicle and performing recovery functions. The ECU may conduct diagnostics on the received power and execute jumpstart mode steps if the power is acceptable. These steps may include powering and activating a vehicle access system to authenticate a user, activating latches to allow vehicle access, or providing power to seats or other components in order to obtain battery access. The ECU may determine whether to charge the low voltage battery based on diagnostic results.

Abstract: Voltage control of electric vehicle batteries is provided. A system can include an electrical circuit of an electric vehicle that can include a plurality of power supplies and a driver component that can be configured to be energized by the plurality of power supplies and provide a voltage greater than a threshold from a battery of the electric vehicle to a motor of the electric vehicle. The electrical circuit can include a switch module that connects the driver component with the plurality of power supplies. The switch module can detect that the electric vehicle generated a signal to actuate an element of the electric vehicle and disconnect, in response to the detection, the driver component from the plurality of power supplies to reduce the voltage provided to the motor below the threshold.

Abstract: Systems and methods are provided for controlling power modes of a vehicle and for providing passive entry to the vehicle. A sleep command can be sent from a central controller to multiple domain controllers to enter a sleep state. When the sleep command is received by a first domain controller, a sleep state is entered. When the sleep command is received by a second domain controller, a stealth state is entered. While in the stealth state, the second domain controller periodically wakes up from a sleep state to monitor a condition. In response to detecting a first condition, the second domain controller returns to the sleep state. In response to detecting a second condition, the second domain controller sends a notification of the second condition to the central controller.

Abstract: Some embodiments may provide a method for a desired operating environment. A signal to place a vehicle in a designated mode corresponding to a desired operating environment may be received. The designated mode may include modifications to one or more default operating characteristics of the vehicle. The modifications may be while the vehicle is in parked mode and a vehicle access key associated with the vehicle is within proximity of the vehicle. In response to receiving the signal, characteristics of the vehicle to be modified in order to create the desired operating environment may be identified. The default operating characteristics may relate to lighting or displays controlled by the vehicle, sounds controlled by the vehicle, or a passive entry system of the vehicle. One or more settings of the vehicle to change the default operating characteristics of the vehicle while in the designated mode may be modified.

Abstract: Particular embodiments may enable configuring settings of a vehicle in a designated mode. A signal to perform a vehicle leveling process using an electronically controlled suspension of a vehicle may be received. A roll angle and a pitch angle of the vehicle as parked may be assessed based on data received from a position sensor built into the vehicle. Signals to adjust an electronically controlled suspension of the vehicle to reduce the roll angle or the pitch angle so that the vehicle is level as parked may be sent based on the assessed roll angle and pitch angle exceeding a threshold value. Data may be transmitted to present information related to the vehicle leveling process in a graphical user interface.

Abstract: A virtual high voltage interlock is disclosed that utilizes a software-based function (e.g., an electronic control unit) to determine if there are any open wires or connectors, based on voltage signals reported by internal components, to prevent high voltage exposure. The electronic control unit instructs a power source to charge a DC bus to a safety voltage, receives measured voltage readings, via a control area network, from at least one high voltage component coupled to the DC bus, and provides an operating voltage to the DC bus in response to the measured voltage readings being acceptable.
