EPAS systems work by using an array of sensors, control units and an electric motor. A torque sensor mounted to your car's steering column measures the amount of force you apply to the steering wheel. The torque sensor, along with vehicle speed and steering angle sensors, sends this information to a control module.

In conclusion, the components of the EPS electric power steering system work together to provide precise and effortless steering assistance. By monitoring the driver''s input and the vehicle''s dynamic conditions, the system ensures optimal steering performance and enhances the overall driving experience.
How Does Electric Power Steering Work The electric power steering system assists the brake system to help operate advanced stability control and accident avoidance systems. If your vehicle loses electrical power or detects a concern when you are driving, the system switches to reduced steering assist or manual steering.
Next came hydraulically-assisted steering, which dominated the automotive world from 1951 when pioneered by Chrysler. This form of system uses a hydraulic pump which is powered from a belt attached to the engine. A power ram is moved by the hydraulic fluid which is pressurised through the movement of the belt.
Increasingly sophisticated electric assistance is the future direction for steering systems. How it works: Electric Power Steering (EPS) Electric power steering (EPS) is yet another of those new-fangled gadgets that has attracted bad press. But there''s a reason why the world''s car manufacturers are adopting it – and it''s all to do
It is the latest type of power steering system in which the hydraulic system from the hydraulic power steering is completely replaced with electric motors and electric sensors, instead of using hydraulic force,the motor driven by the vehicle''s battery is used to apply force on the steering gear and torque provided by the motor is controlled
Learn how a typical power steering system works, familiarize yourself with its components, and see example power steering system diagrams. Need Parts? Download the CarParts App . Most vehicles have either electric power steering (EPS) or hydraulic power steering. There are also a few models that use an electro-hydraulic system, which
Between the hydraulic and electric types of power steering, there''s a hybrid of the two systems called electrohydraulic. It functions like a hydraulic-assist system, only that the hydraulic pressure is created by an electric motor, rather than driving the pump off the engine.
EPAS stands for Electric Power Assisted Steering. Electric Power Steering (EPS) is the another name for EPAS. In almost all modern vehicles, Electric Power Steering is in use. The main purpose of any type of power steering system is to attenuate the driver effort required to steer the vehicle i.e. the torque applied on the steering wheel and it
The Electric Power Steering System with Belt Drive Servo Unit controls and assists the steering for mid-size vehicles, SUVs, transporters and even pick-up trucks with off-road capability. Open solution page. Electric Power Steering Servo Unit on a Second Pinion .
The idea behind EPS is the same as the idea behind hydraulically assisted power steering systems: Reducing the amount of effort needed to turn the steering wheel. EPS simply uses an electric motor to provide the assist rather than use a hydraulic pressure system.
The EPS system uses a brushless motor, where the rotor (armature) turns inside the stator (there are other types). Three separate stator windings produce electromagnets. The polarity of the magnet depends on the direction of current flow so the current flowing through winding A from A1 to A2 will produce a south pole at A1 and north pole at A2.
EPAS has several components that work together to provide power assistance to the steering system. These include: Electric Motor – The electric motor is the main component of the EPAS system. It provides power assistance to the steering system and is controlled by the ECU. Sensors – Sensors are used to detect the steering input from the
Electric power steering systems have gained popularity in recent years due to their efficiency and versatility. Instead of hydraulic pressure, these systems employ an electric motor to assist the driver''s steering inputs.. The electric power steering motor is connected to the steering column and can adjust the steering assistance based on various factors such as
GM vehicles have used electric power steering (EPS) systems for almost a decade now, so odds are good you''ve already worked on a vehicle using the system. Interestingly, it''s not just expensive or luxury models that use EPS.
Some electric power steering systems can alter the amount of resistance the driver feels when turning the wheel. The electric motor can provide more assistance during low-speed maneuvering to lower the level of effort it takes to turn the wheel. That, in turn, makes moving around tight parking lots and side streets less difficult.
A power-steering system should assist the driver only when he is exerting force on the steering wheel (such as when starting a turn). When the driver is not exerting force (such as when driving in a straight line), the system shouldn''t provide any assist. The device that senses the force on the steering wheel is called the rotary valve.
The power steering unit has: A valve body with four valves. Two power cylinders have pistons one on each side.; The Valves will deliver the oil to help in making a turn. This works on the endwise movement of the steering column shaft.
What is power steering and its types? Power steering is a technology used in vehicles to reduce the effort required for steering. There are various types of power steering systems, including Hydraulic Power Steering (HPS) using hydraulic fluid and a pump, Electric Power Steering (EPS) with an electric motor, Electro-hydraulic Power Steering (EHPS)
Electric Power Steering (EPS) revolutionizes steering assistance by harnessing an electric motor and control module to provide effortless torque for steering.This mechanism relies on advanced steering sensor technology to detect the driver''s input and adjust the amount of assistance needed. The electric motor efficiency of EPS systems guarantees that steering
In terms of race modes and sports buttons within performance cars of the last decade, EPAS systems allow adjustments to be made in the weight and speed of the steering input simply by changing...
Also known as EPS or EPAS (Electronic Power Assist Steering), this system featured an electrically driven pump with a normal rack and pinion steering gear. This design was expanded upon and improved vastly during the next two decades. Steering Into the Future. Modern Electric Power Steering systems consist of several cooperating components
Electric power steering (EPS) is the norm on today''s new cars. There''s still a solid metal steering shaft running from the steering wheel to the steering rack, which steers the tires, but the rest
And that means that you need to know how the system works, what goes wrong and how to fix it – quickly, safely and profitably. The idea behind EPS is the same as the idea behind hydraulically assisted power steering
How Does Electric Power Steering Work? Opposed to a hybrid power steering system, where a hydraulic pump is run by an electric motor, electric power steering systems are fully electronic and they work by combining all the information from each of the main components mentioned above. Let''s begin with how EPS systems work.
The motor employed for Electric Power Steering (EPS) system gear assembly is a permanent magnetic field DC motor. This motor generates steering assisting force required to turn the wheels. The motor should be able to produce torque without turning and also, to reverse the rotation rapidly.
2) Electric Power Steering System (EPS) Electric power steering is one of the latest types of power steering systems. In this system, an electric motor is utilized to multiply the steering input force instead of the hydraulic fluid. An electric power steering system works in the following way:
Electronic power steering offers many benefits compared with engine-driven mechanical power steering. But diagnostic and repair procedures are very different. Here''s what you need to know. EPS offers several advantages over hydraulic power steering (HPS). One of the primary drawbacks of HPS is that the hydraulic pump is typically tied to the internal combustion engine
Power steering systems used to have hydraulic operation, which worked by sending fluid from a reservoir through a pump on a car''s steering column to make turning the steering wheel easier. If you''ve driven an older car — or one with a failing power steering pump — you''ve probably noticed how heavy steering is without this assistance.
The first power steering system on a vehicle was apparently installed in 1876 by a man with the surname of Fitts, but little else is known about him. [2] The next power steering system was put on a Columbia 5-ton truck in 1903 where a separate electric motor was used to assist the driver in turning the front wheels. [2] [3]Robert E. Twyford, a resident of Pittsburgh, Pennsylvania,
