Electric Power Steering (EPS)
Electric power assisted steering (EPAS) systems have gained wide market acceptance over the last several years. The main advantage of an EPAS system over a hydraulic one is the use of an electric motor. This provides directional control to the vehicle driver and reduce engine loading, resulting in improved fuel economy. Typical systems employ avariable-assist feature, which provides more assistance at lower speeds and less assistance at higher speeds. ST, with its broad portfolio of power drivers for brushless motor control, coupled with our advanced 16/32 bit microcontroller product families and an extensive standard product offering, is the obvious choice for any power steering application. A sampling of ST products applicable to power steering control systems are shown in the block diagram above.
