How does an electric power steering system work?
The electric power steering uses an electric motor that draws energy from the vehicle’s electrical system to provide steering assistance. Sensors detect the torque or effort that the driver is applying at the steering wheel, and a computer decides how much assist needs to be added.
What is electronic steering system?
Electric power steering (EPS) is a key technology for highly automated driving. The Bosch EPS variants meet the requirements for small, mid-range, sports cars as well as light commercial vehicles. The EPS has an electric motor which controls the vehicle steering.
What are the three operating modes for the EPS system?
The system has three operating modes: a “normal” control mode in which left or right power assist is provided in response to input from the steering torque and rotation sensor’s inputs; a “return” control mode which is used to assist steering return after completing a turn; and a “damper” control mode that changes with …
How do you maintain electric power steering?
How to Maintain the Power Steering System
- Have your power steering fluid checked regularly.
- Change your Power Steering Filter Yearly.
- Keep your fluid clean by have a power steering flush performed.
- Most issues within the power system arise because of power steering fluid leaks.
What is difference between electric and power steering?
The Electric power steering simply uses a electric motor to direct the steering commands made by the driver easily whereas, a Hydraulic power steering uses pumps and piston for the same. The electric power steering is more efficient and works to the point.
What are the components of electronic power steering system?
What is it made up of? Electronic power steering or electronic power assisted steering (EPAS) is comprised of four main parts; the motor, reduction gear, torque sensor, and a module that collects and sends out information.
What are the components of electric power steering system?
What are the four primary types of electric power assist steering systems?
There are four forms of EPS based on the position of the assist motor. They are the column assist type (C-EPS), the pinion assist type (P-EPS), the direct drive type (D-EPS) and the rack assist type (R-EPS).
What are the types of power steering?
3 Types of Power Steering Systems
- Hydraulic Power Steering.
- Electro-Hydraulic Power Steering.
- Electric Power Steering or Motor-Driven Power Steering.
How is electric power steering diagnosed?
The main indication you’ll get if there is a malfunction with the electric power steering system is that the EPS light will illuminate on the dashboard. Specifically, the warning light will come on when the EPS system is off.
What is the advantage of electric power steering?
Advantages include: Energy efficiency / fuel efficiency since the power steering pump is a parasitic device at all times whereas the electric motor only needs energy when turning. Lower mechanical complexity and less weight, also contributing to fuel efficiency.
What is the principle of electric power steering?
Principle of operation •When the driver turns the steering wheel, electric power steering provides an assistive torque to help to steer the wheels. •This assistive torque is provided by an electric motor. The torque is applied to the rack -and pinion system via a motor and reducing gear assembly.
What is an electric steering assistance motor?
•The electric motor is called the steering assistance motor. The power which the control unit requests to drive the motor is dependent on two variables: the torque applied to the steering wheel and the vehicle’s speed.
How do you diagnose electric power steering systems?
Diagnosing electric power steering systems requires an understanding of voltage, current and loads. Also, a technician must understand how the modules and sensors work together to determine the level of assist. Most electric power steering systems use a three-phase electric motor powered by a pulse width modulated DC voltage.
What is EPAS (electric power assisted steering)?
As EPAS (electric power assisted steering) systems have been developed and refined however, manufacturers like Porsche have managed to create electronic systems that all but match the feel of a hydraulic system and then go on to surpass the mechanical method in many fields.
