Mike Dabrowski told me he put an ammeter on the EPS and measured currents as high as 20amps, but he didn't say under what conditions.If you had an ammeter on the EPS, I'd bet it would be less than an amp at 30 mph and up.
Yes, and as I understand it there is no load if you are steering straight ahead? And does it draw current only to angle the front wheels, or does it continue to draw current to keep the wheels turned?The EPS will only use as much power as it needs. Just like hydraulic power steering, the 'boost' is proportional to the load. If you are moving fast, there isn't much load on the steering shaft, so the boost is low.
Still, I'm at a loss to figure out why Honda included it on the Insight-I when they went to such extreme lengths to save weight and conserve energy in other areas. And the fact remains that manual steering was perfectly adequate on many previous vehicles of even greater weight, plus the Insight-I's skinny tires shouldn't require a lot of effort to steer. Perhaps the EPS is lighter than a manual steering system?Low speed, you get the boost to help turn the wheels.
