Subaru Electric Power Steering: How It Works and Boosts Your Driving Experience

If you’re a car enthusiast or a mechanic, you might be familiar with the traditional hydraulic power steering system, which uses fluid to help drivers turn the steering wheel. However, Subaru has introduced an innovative electric power steering (EPS) system that provides many benefits. In this article, we’ll explore how Subaru’s EPS system works, its differences from hydraulic steering, and its advantages and disadvantages.

Understanding Electric Power Steering

Electric power steering is a system that uses an electric motor instead of hydraulic fluid. The motor is connected to the steering gear and assists the driver by helping turn the wheels.

The Subaru EPS system is made up of two main components: the power assist motor and the steering angle sensor. The motor provides the necessary power to assist the driver in turning the wheel, while the sensor constantly measures the position of the steering wheel and the direction of the car.

Pros and Cons of Electric Power Steering

Electric power steering has several advantages over hydraulic steering. One of the most significant benefits is improved fuel efficiency. Without the hydraulic fluid, the EPS system reduces the load on the engine, allowing for better gas mileage.

Another benefit of electric power steering is its speed-sensitive assistance. The EPS system can adjust its level of assistance based on the speed of the vehicle. At low speeds, such as when maneuvering in a parking lot, the steering wheel’s effort is lightened, making it easier to turn. As the vehicle’s speed increases, the system reduces the assistance, giving the driver more control for highway driving.

However, there are some drawbacks to electric power steering as well. One of the most significant drawbacks is that it’s entirely dependent on electrical power, so if something goes wrong with the electrical system, the EPS system will stop working. Additionally, the steering wheel may feel less natural than with hydraulic steering, which some drivers may find less appealing.

Subaru Electric Power Steering

Subaru’s EPS system is specifically designed to improve the driver’s experience. One of its primary features is the vehicle stability control, which helps keep the car stable during turns. The system works by using the steering angle sensor to detect when the vehicle is about to understeer or oversteer. It then sends a signal to the vehicle stability control module to apply brakes to individual wheels, resulting in better stability and control.

The Subaru EPS system also includes an emergency self-diagnostic function. If the system detects an electrical or mechanical malfunction, it will automatically switch to a fail-safe mode to maintain basic steering capabilities. This ensures that the driver can still safely operate the vehicle until they can take it in for repairs.

Conclusion

In conclusion, electric power steering offers many benefits over hydraulic steering, including improved fuel efficiency and speed-sensitive assistance. Subaru’s specific EPS system includes features like vehicle stability control and emergency self-diagnostic functions, making it a great option for drivers who want improved control and safety. Understanding Subaru’s EPS system, its pros and cons can help drivers make an informed decision when choosing a car with this technology.
