Abstract: Systems and methods are provided for mitigating motion sickness. When motion sickness is predicted, the motion sickness mitigation system alters vehicle performance, cabin conditions, and/or alerts the occupant to upcoming vehicle actions, to avoid or alleviate motion sickness. A controller includes a processor that receives an occupant profile and traffic information for an upcoming trip of the vehicle on a route. Using the occupant profile and the traffic information, the processor calculates whether the occupant will experience motion sickness when the vehicle travels on the route. A vehicle performance signal correlated to the calculation, is delivered by the processor to initiate motion sickness mitigation. The vehicle performance signal varies operation of a steering actuator, an acceleration actuator, and/or a brake actuator to implement the motion sickness mitigation.

Abstract: A vehicle including a hybrid battery pack includes a first battery pack and a second battery pack. The first battery pack has a higher energy density than the second battery pack. The second battery pack has a higher power density than the first battery pack. A power inverter module is connected between the hybrid battery pack and a motor generator unit (MGU) that is connected to a powertrain of the vehicle. The power inverter module is configured to regulate power flow between the hybrid battery pack and the MGU. A battery management module is configured to: control switching of the power inverter module; selectively charge and discharge at least one of the first battery pack and the second battery pack; and selectively charge the first battery pack with power from the second battery pack.
