Electronic Power Steering (EPS)
Compact and lightweight, EPS eliminates many of the parts used in a conventional hydraulic sterring system (pump, hoses, fluid, etc.) for reduced maintenance and repairs.
Without the drag of a conventional power steering pump, EPS is able to improve both engine power output and fuel economy. (Toyota estimates up to 3% improvement in mpg figures.)
EPS makes you safer.
To understand how Toyota's Electronic Power Steering is more than just another power steering system on Venza you must first understand how Vehicle Stability Control works. VSC is just one part of Toyota's Star Safety System that is standard on the new Venza.
Even the best drivers can get caught by a bend that tightens unexpectedly – or the need to brake suddenly in mid-corner. Either action can unsettle the balance of the car. That's when VSC steps in to help the driver regain control quickly.
Sensors continuously monitor and cross-reference speed, steering angle, yaw rate and deceleration. The instant the system detects a loss of control, VSC steps in and momentarily dictates the individual braking force sent to each wheel. It also moderates the throttle until the tendency of the front to run wide (understeer), or the rear to break away (oversteer), is corrected.
Notice that VSC only controls the brake system and throttle. Steering is other very important input and is left up to the driver. During an unexpected driving situation that leads to a skid many things are happening not the least of which is PANIC! During a skid, what direction do you steer? The answer is that you steer into the direction of the skid and this can be counter intuitive to many people. Even if we know what direction we are supposed to turn the wheel, it isn't something that is common. Your heart is in your throat you see you life pass right in front of your eyes and through all of this you need to be a physics professor and know the correct steering inputs.
