What is Electric Steering and how does it work? What are the advantages of electric steering?
Today, hydraulic steering systems are commonplace (Hydraulic power steering / HPS). It has been replaced by the electric steering system (Electronic power steering / EPS). . The greatest advantage of EPS is its ability to provide steering support for the driver, even when the engine stops. This can be a drawback. You may lose steering assistance if there is an electrical or electronic fault in the EPS.
Electric steering systems are more fuel efficient, require fewer parts, and have lower maintenance costs. These are just a few of the many benefits that this system offers.
The electronic steering wheel includes the steering pump, hoses and drive belt. This eliminates the need for certain parts. Instead, it uses an electrical motor. It is lighter and smaller than hydraulic systems. It features a variable power balance system which provides more support for low vehicle speeds than high speeds. It does not start the EPS motor continuously like power steering systems which run a continuous hydraulic pumps. It saves fuel more than cars with an HPS system. It offers a 0.2-liter fuel saving per 100 km
The EPS system also has the advantage that the ECU software is easily adjustable. You can enjoy many benefits, such as better steering feel, speed functionality, vehicle-specific settings, and a lower cost. EPS can also compensate for unilateral forces, such as a flat tires. It can also be used to assist in emergency maneuvers and has electronic stability control. The steering wheel can be controlled by the ECU, and the vehicle can also park itself. ECU and sensors can be combined to track the vehicle’s position using the lane tracking feature.
Safety mechanisms in EPS systems can shut down engine power if an ECU problem is detected.
What are Electric Steering Faults (ESF)?
An electric assisted steering wheel is made by connecting a shaft to the steering wheel, and a geared motor to the rack-and-pinion mechanism. These steering wheels offer high driving comfort as they are quieter. But, emissions and fuel consumption are very low. The most serious problem with electric power steering, however, is the electrical fault within the motor. Other malfunctions are also possible.
Some of these malfunctions may be listed here:
Steering Stiffness: Steering wheel stiffness can be caused by excessive resistance or force. To understand why this happens, you should inspect the steering box, ball joints and king pin.
Roaming: This is when the car doesn’t follow the steering wheel’s instructions and instead takes a different route.
Steering Warning Light Not On: Normal for the warning lamp to turn on after starting the engine is turned on is. Problem is, the warning lamp doesn’t go out when the engine starts. This is a sign of a system problem.
Steering Angle Sensor Failure: The steering angle sensor detects the steering angle of your vehicle steering wheel and calculates the angular velocity. The steering system still works mechanically, even if it is disabled. There may be an angle sensor malfunction that is causing difficulty in turning the steering wheels.
Failure of Steering Controller Unit: Control The steering control unit is responsible for controlling the pump motor’s angular speed and vehicle speed. Hydraulic oil heat can cause the system to fail.
