Electric power steering

[dodge man]

With traditional power steering you weren稚 suppose to hold the wheel against lock for more than a couple of seconds. It would make the pump go into relief like a pump on a tractor will.

Does the same rule hold true for electric power steering?

 

[grapeview8n]

holding at lock will cause over temperature protection to kick in. you will loose assist temporarily until steering motor cools off enough for operation. same goes for extended parking lot type operation.

I'm not sure why you would. It doesn't turn any sharper.

Electric power steering works differently that hydraulic. As you turn the steering wheel and the wheels don't you put pressure on a switch. When the pressure is great enough on that switch it turns on the electric motor to assist you. How much force it gives you is based on how much power is sent to the motor. It's all computer controlled. The computer knows the position of the steering wheel, which direction you are turning it, how fast you are going, and the position of the steering box. I would doubt that they would put that much engineering into the system and not add in limit switches to stop putting extra pressure on the steering system when the system was being overloaded (trying to turn your wheels when against a curb, reaching the racks limits, etc). In the future it will most likely be fly by wire and the steering wheel wont be connected to nothing but sensors and a force feedback system like a joystick for a computer game has.

"fly by wire" Is that the same thing as "flying by the seat of your pants" when the electronics and computers do what they do when they go "haywire"?

We've had 2 cars with electric steering. No problems at full lock on either one.

Have an F150 with electric steering (lol) and to be honest I don't notice any difference between it and any other vehicle. I am not a lock to lock "turn tighter **** it" person though.

Actually, there are some cars with no actual connection between the wheel and the steering gear unless there is a failure in the electronics. The future is now. Unless, of course, you want real steering "feel" in your car.

I am not a fan of EPS; snowmobiling a couple years ago, we got ready to leave the camp, -25*F. Started the truck( half an hour) to warm everything up, backed onto the highway, turned the steering wheel and the dash panel lit up like a Christmas (sorry, holiday tree). 185 miles of wondering if we were going to go into limp mode and take us 2 weeks to get home. Give me the old hydraulic steering anyday. The repair was a power steering pressure sensor for $125 + and a PITA to change

Experienced electric steering failure on my 2012 f150 at 65k. Very disappointed. Cost about 1600 to repair and ford lost a customer. Almost caused a wreck too.

Electrical power steering is a requirement for self driving cars and trucks.

Not sure if this counts or not. We use ATV's and UTV's which all have electric assist steering and done so for +-15 years. These are all work machines and see many, many hours of hard use before retirement. Among these, we've had zero failures or maintenance on these units. The UTV we have now weights about 1800lbs and you can steer it while static and on pavement. Its quite powerful! We'd not get a machine without it.

At that weight it would be like having a tractor without power steering.

.......... the steering wheel wont be connected to nothing .......

When I was a kid, we had a Morris Minor given to us. Its steering would occasionally do this.

Neighbor had the EPS take a dump on him, he then hit a curb and was stranded...

He said it cost him 1K to get it fixed...
