Abstract:
A method of for authenticating a mobile device for operating a vehicle may include receiving, by a receiver of the vehicle, an operation request from the mobile device to actuate an operation of the vehicle and generating, by a controller of the vehicle, a locally-perceivable signal indicative of a passcode granting a connection with the mobile device, in response to the received operation request. The method may further include receiving, by the receiver of the vehicle, information relating to the passcode from the mobile device, and establishing the connection with the mobile device for actuating the operation of the vehicle if the received information is authenticated.
Abstract:
Certain embodiments are described that provide a method for measuring battery parameters under discharge/charge. (a) A battery at rest is provided having an initial State of Charge (SoC). (b) A discharge/charge excitation is applied for a first period of time. (c) The battery is allowed to rest for a second period of time. (d) A discharge/charge is applied, having a higher current and shorter duration than the discharge/charge of step (b). (e) The battery is allowed to rest for a third period of time. (f) Steps (b)-(d) are repeated. Parameters of the battery are measured during a plurality of the steps.
Abstract:
A three-phase current sensor for measuring currents running in three conductors of a three-phase conductor system includes at least a first magnetic measuring device. The magnetic measuring device includes a magnetic circuit provided with at least two gaps and a magnetic field sensor arranged in each gap of the magnetic circuit. The magnetic field sensors are positioned on both sides of a cavity sized to receive one of the three conductors. The gaps and thus the magnetic field sensors are positioned such that stray magnetic flux from an adjacent conductor has substantially equal amplitude passing through each of the sensors.
Abstract:
A system and method for adjusting drive mode of a vehicle are disclosed. According to certain embodiments, the system may include a processor configured to: receive sensor data generated by one or more sensors in communication with the processor; determine motion of the vehicle based on the sensor data; determine, based on the motion of the vehicle, characteristics of the surface or driving behavior of a user of the vehicle; and determine a drive mode of the vehicle based on the determined characteristics of the surface or driving behavior of the user. The system may further include one or more actuators configured to implement the drive mode.
Abstract:
Certain aspects relate to systems and techniques for flexibly and movably mounting a charge port in front-facing portions of an electric vehicle. When not in use the charge port can be concealed by the body of the vehicle. In a pre-charging or charging mode the charge port can be automatically moved to a charging position where it is exposed through the vehicle body and thus available for coupling with a charging connector at a charging station. Further, the charge port can be flexibly mounted to the vehicle so as to absorb impact forces in one or more directions. The charge port can include oscillation dampening mechanisms for electrical cables coupled to the charge port.

Abstract:
A camera system for a vehicle may include a control interface configured to receive an input from a driver and generate a signal, and at least one camera configured to capture video of an interior of the vehicle. The camera system may also include a display configured to output video to the driver, and a controller in communication with the control interface, the camera, and the display. The controller may be configured to receive the signal from the control interface, actuate the at least one camera to capture video based on the signal, and output the video to the display based on the signal.
Abstract:
A camera system for a vehicle may include a manual control configured to receive an input from an occupant indicative of a vehicle operation and responsively generate a signal. The camera system may also include a turn signal configured to illuminate and a camera configured to capture video of an area exterior to the vehicle. The camera system may further include a display configured to display video, and a controller configured to receive the signal from the manual control, actuate the turn signal to illuminate based on the signal, actuate the camera to capture a video based on the signal, and output the video to the display based on the signal.
