For this reason, most sports cars have used hydraulic power steering or no power steering at all for decades. The PSCM combines inputs such as steering shaft torque sensor, vehicle speed (via serial data), calculated system temperature, and steering tuning setting to determine the amount of assist required for example, greater assist would be provided at slow-speed parking than during a high-speed lane change and commands the correct amount of current (or assist) to the power steering motor. Without power assist, the steering of most vehicles would be extremely heavy, particularly during low-speed maneuvers such as pulling into a parking spot, turning a 90-degree corner in the city, or maneuvering in a crowded gas station. Electric power steering systems are relatively simple and consist of just a few components. Electric steering is a relatively new technology, and as such, there is not a lot of information available on what happens when it fails. The EPS system is more efficient than hydraulic systems since it only needs to provide assist when the driver is actually steering (rather than robbing energy from the vehicle's engine to rotate the hydraulic pump constantly), and it keeps the environmentalists happy since there's no harmful fluid involved that needs to be flushed or drained.

If you buy a car today, it will likely have a major difference in the power steering than cars from 10 or even just 5 years ago: The steering system will rely on an electric motor instead of a hydraulic piston for power boost. In a fully electric power steering system, . A computer rates the amount of turn input from the driver, then sends instructions to actuators at either a steering rack or the front wheel control rods. Check the Battery Voltage Signal on the scan tool as well as checking the actual available voltage and ground supply at the PSCM. They are a far cry from manual steering that needs tons of force to turn the wheels. They range from mildly annoying to downright scary so it's important to locate the cause of the problem quickly. If you are interested in purchasing a new car, it is a good idea to research which models have this technology.

They are becoming increasingly common, so it is likely that more and more cars will be fitted with them in the future.". Turning the steering wheel to the right increases Signal 1 Voltage and decreases Signal 2 Voltage. | (Photo by Justin Sullivan/Getty Images) An electric power steering utilizes an electric motor in place of the hydraulic pump. Every other electric power steering system uses a regular steering column connected to a regular rack and pinion with a motor to assist. EPS uses an electric motor that draws energy from the vehicle's electrical system to provide the steering assistance. The Signal 1 and Signal 2 voltages increase and decrease, staying within 2.5 to 2.8 volts of each other as the steering wheel is turned. This electric motor can be located either directly on the steering rackthis arrangement is more expensive and tends to be used on the sports- and luxury-car end of the spectrumor mounted to the steering column.

Therefore, if you are driving a car with electric steering, it is important to be aware of the possibility that the electric motor could fail, and be prepared to take appropriate action if this happens. Electric Power Steering Conversion Kits. But these cars got away without it due to their light weight and relatively narrow tires. The engine speed, which varies from 1,200 to 6,500rpm in a typical car, affects the hydraulic pump speed. However, the good news is that engineers have spent much time and effort through the years evolving electric power steering and creating sophisticated algorithms that faithfully re-create the steering sensations lost after the switch from hydraulic units. Given the advantages of EPAS, I expect more cars to convert to this system as they receive model updates. It is becoming increasingly common, as it is seen as a more efficient and environmentally-friendly alternative to traditional hydraulic power steering. Contact between the front stabilizer shaft and its bushings. Others can sense wheel speed and traction control input. A Ford Focus and Fusion electronic power assisted steering (EPAS) lawsuit won't be certified as a class-action after a judge ruled the plaintiffs can't prove all owners experienced harm from the alleged defect. housing.
