Abstract: Methods and systems are provided for a traction system of a vehicle. In one example, a method includes selecting between strategies for activating a steady state of an inverter based on an electric motor speed and a de bus voltage. The strategies include activating an active short circuit (ASC) or a hardware active short circuit (HASC) based on an activity of a controller. The strategies may further include a freewheel strategy.

Abstract: A deflector arrangement for a tractor is provided, the tractor being connectable to a trailer that forms an aerodynamic drag source. The deflector arrangement includes a deflector, a mount for connecting the deflector to the tractor, an arrangement for selectively deploying and retracting the deflector relative to the tractor, a sensor arranged to sense that the trailer that forms the aerodynamic drag force is attached to the tractor and send a loaded signal in response thereto, and a controller arranged to receive the loaded signal from the sensor and to control the selectively deploying and retracting arrangement to deploy the deflector in response to the loaded signal.
