A method includes receiving, by a processing device of a vehicle, a plurality of real-time measurements related to at least one current vehicle condition. The method also includes providing, by the processing device, the plurality of real-time measurements to a long short-term memory (LSTM) machine learning model. The method also includes predicting, by the processing device and using the LSTM machine learning model, a longitudinal speed of the vehicle based on the plurality of real-time measurements. The method also includes determining, by the processing device, a longitudinal slip ratio of each axle or of each wheel. The method also includes initiating, by the processing device based on the determination of the slip ratio, one or more vehicle actions to compensate for the slip ratio.

A vehicular airbag deployment system includes an airbag storage chamber, the airbag storage chamber disposed at a location within a vehicle. The vehicular airbag deployment system also includes an airbag configured to be stored within the airbag storage chamber when the airbag is in a deflated state. The airbag is further configured to be inflated in response to a collision detection event and deploy from the airbag storage chamber. In an inflated state, the airbag extends in a generally horizontal direction between a passenger seating location and a reaction surface at a front interior surface of the vehicle and the airbag contacts the reaction surface in the inflated state.

A method includes receiving, by a processing device of a vehicle, one or more measurements related to a component of the vehicle. The method also includes determining, by the processing device, based on the one or more measurements, a failure rate and a mean time to failure (MTTF) for the vehicle component. The method also includes transmitting, by the processing device using a communication interface, the failure rate and the MTTF to one or more destination systems. The method also includes implementing, by the processing device based on a determination of a failure rate increase for the vehicle component, one or more actions to increase an operation lifetime of the vehicle component.

An electric motor controller is equipped to mitigate drive line induced vehicle vibration. The motor speed is measured at the output of the motor, separately from any measurement of drive shaft or wheel speed. At least bandpass filtering is applied to the measured motor speed, at a pass band based on the natural frequency of the drive shaft. The filtering detects drive line induced oscillations of the motor speed. A controller uses the detected drive line induced oscillations to generate an oscillation control output, subject to limiting. An oscillation mitigation torque signal corresponding to the control output is added to a torque command for desired motor speed, to adjust for the oscillations. The adjusted torque command is used to control the motor, with a significant reduction in the oscillation of the motor's speed.

Common mode voltage discharge shields are disposed over end turns of stator windings for a three phase electric traction motor within an electric vehicle. The common mode voltage discharge shields are capacitively coupled to the end turns to a ground strap, providing a low impedance path for common mode voltages accumulating at a neutral for electric traction motor as a result of high frequency switching of the motor drive voltage to produce desired torque. An insulating layer separates the common mode voltage discharge shields from the end turns. Accumulation of the common mode voltage in excess of a bearing breakdown voltage, and the associated potential for discharge through bearings between the stator and rotor and electrical discharge machining, is reduced or eliminated.

Described herein are steer-by-wire systems and methods of operating these systems in vehicles. A steer-by-wire system comprises a steering wheel assembly, comprising a steering wheel, sensors, and a torque generator. The system comprises a rack assembly, comprising a steering rack, sensors, and a rack actuator. The steering wheel assembly and the rack assembly are communicatively coupled by a steer-by-wire system controller, without having any direct mechanical links between the assemblies. In some examples, the controller instructs the rack assembly to control the steering rack position based on the steering input, such as changes in the steering wheel position. A steering map is used to determine the desired steering rack position based on the current steering wheel position. In some examples, a steering map is selected from a steering map set based on, e.g., the vehicle speed, vehicle direction, driver preference, and the like.

An apparatus includes an interconnect assembly configured to receive and retain multiple batteries. The interconnect assembly includes a retainer configured to receive portions of the batteries and a conductive interconnect layer carried by the retainer. The conductive interconnect layer includes a first layer of conductive material having a first thickness and a second layer of conductive material having a second thickness less than the first thickness. The first and second layers of conductive material are attached together to form the conductive interconnect layer. The second layer of conductive material includes multiple interconnects configured to be coupled to cathodes and anodes of the batteries.
