Power Steering
Electric power assisted steering (EPAS) systems have gained wide market acceptance over the last several years. The main advantages of an EPAS system over hydraulic is the use of an electric motor to provide directional control to the vehicle driver and the reduction in engine loading resulting in improved fuel economy. Typical systems employ variable assist, which provides more assistance at lower speeds and lower 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 that are applicable to Power Steering Control systems can be found in the following block diagram.
