Abstract: Technical solutions are described for facilitating an electric power steering (EPS) system to determine an operating mode of a vehicle that is equipped with the EPS, where the operating mode is indicative of a level of autonomous driving being used by the vehicle. The technical solutions further facilitate detecting a change in the operating mode of the vehicle, and facilitating a transition in computing an assist signal for the EPS system during the transition between the operating modes.

Abstract: One or more embodiments are provided for an inverter. The inverter includes a phase switch configured to supply AC power via an output terminal. The phase switch includes a high-side leg and a low-side leg. The high-side leg includes a high-side solid-state switch configured to selectively conduct current between a high-side conductor of a DC bus and the output terminal, and the low-side leg includes a low-side solid-state switch configured to selectively conduct current between the output terminal and a low-side conductor of the DC bus. The high-side solid-state switch has a first conducting-state resistance value, and the low-side solid-state switch has a second conducting-state resistance value different than the first conducting-state resistance value. A shunt resistor may be connected in series with a corresponding one of the high-side solid-state switch or the low-side solid-state switch, balancing the resistances of the high-side leg and the low-side leg.

Abstract: A pulley assembly for a road wheel actuator assembly includes a driven pulley assembly, a driven pulley, and a belt. The driven pulley assembly includes a driven pulley and a retainer. The driven pulley is at least partially disposed about a ball nut that is operatively connected to a rack bar. The retainer is received within the driven pulley. The belt is arranged to connect the driven pulley assembly to the drive pulley.
