Electric power steering (EPS) is a power steering system that uses computers, electronic sensors and a small electric engine to replace traditional, hydraulic power steering. While there are numerous advantages to this system, including increased fuel mileage and a less labor intensive fix, there are also certain disadvantages to electric power steering. Maruti Suzuki Estilo has the powerful EPS to drive with a full throttle.
Electric power steering systems improve auto efficiency and safety. However, electric power steering is still relatively new and costly compared with traditional hydraulic steering.
Upgrading a traditional vehicle's hydraulic power steering system to an electric power steering system is a big project with a hefty cost. Newer cars are built with electric power steering systems in mind, whereas hydraulic systems are larger, clunkier and arranged differently.
Active Steering Systems are evolving in the direction of giving an increasing support in terms of agility, safety and comfort improvement
The automotive industry is showing a growing interest towards the usage of EPS (Electric Power Steering) systems. With the enhancements in mechatronic technologies, they are spreading from small size cars to medium and large size cars. EPS systems provide a number of advantages with respect to hydraulic power steering: first of all lower fuel consumption, then higher product standardization and finally easier customization of feeling performances.
Nowadays, EPS systems are extending their influence from the driving feeling optimization to other driving features including safety, agility and comfort. This is achieved by modifying the conventional assistance torque, based on driver torque and steer angle, through the introduction of contributions based on signals that other ECUs, integrated in braking, vision, obstacle detection systems, compute and make available to the vehicle CAN network. These “torque overlays” determine a useful haptic feedback for the driver, recommending specific wheel steer commands suitable for the peculiar dynamic scenario of the vehicle.
