With Electronic Power Steering (EPS), the hydraulic system is replaced with an electric motor that aids the driver only when needed. Its digital assistance control can be modified online to adapt to driving conditions. There are, however, several design constraints to consider. One is that the driver does not want to lack the haptic feedback from the tires, especially when a vehicle is large, such as a truck. Other constraints are determined by safety regulations, particularly for automatic guided vehicles. These constraints require adopting an efficient, accurate and redundant system. Gallium nitride technology helps the designers in all these areas.
