20220294029 · 2022-09-15 · ·

A battery resistance measurement system measures an electrical resistance of a battery and comprises a determination unit and a measurement unit. The determination unit determines, based on whether a predetermined condition is satisfied, whether a target battery has switched from a charged state to a discharged state in which while the target battery receives supplied electric power the target battery outputs electric power larger than the supplied electric power. The measurement unit starts measuring the electrical resistance of the target battery at a time when the determination unit determines that the target battery is switched from the charged state to the discharged state.

Steering wheel preconditioning

Heating and/or cooling a vehicle interior, and in particular a steering wheel, may include receiving a heating/cooling request, automatically directing heated/cooled air from an HVAC duct through louvers adjacent to a steering wheel into a passenger compartment, and automatically rotating the steering wheel back-and-forth to change the location where the heated/cooled air is blown onto the steering wheel. This may include automatically telescoping and automatically tilting the steering wheel as well. Moreover, an infrared camera may be employed to determine where best to rotate the steering wheel for heating/cooling.
