What determines whether a consumer will "love a car"? its how the car "feels" when a person drives the car Does it feel liek they are one with the car or do they feel plush an separated from the automobile technology? This is a personal preference and should remain so, some people like a "plush driving feel while other prefer a tight gokart experience. Many assume that to drive in a tight city should be a certain experience, and the aim of this concept is to allow the car to "change the way it feels to drive the car", while the mechanicals of the car provide the most efficient operation for a given road condition or environment. For example, city driving in the future may be limited to speeds of less than 30 miles per hour with an electric drivetrain at 90 degree turns going up and down city blocks. For such operating conditions a small vehicle with a tight suspension and low end gearing might suffice for maximum energy conservation. Thsi vehicle will "feel" a certain way to the consumer. By varying this feel and enabling people to adjust the "feel" of the car to their preferences, they will "enjoy" driving the car more in that environment. For example driving a gofl cart versus an M3 on a twisty road. The M3 is much more communicative and "at one" with the driver than the M3. Body cell separated from the suspension components. Magmetic rheological components to limit body lean and flexure. Active shocks to tighten on the entrance of a tight turn and then loosen on the exit to make the tight 90 degree turn "feel" more exciting. Central body component retains it center of gravity despite body rolland flex. Use 3 preference settings, loose, communicative and sporty. User selects and chooses from a central touchscreen An other way to control the system is to measure how fast does the driver react, very fast and twitchy means car is driving beyond them and scaring them, tune it down. Also reads the grip on the steering wheel and vocal commands "whoa" if said more than once. Laugh and smile means tighten the dynamic if able to gauge the facial expressions with a camera. Design: 3 point magnetorheologcial dampners on each suspension hardpoint for 3 way dynamics. A three piece magneto-rheological (MR) bushing consisting of 3 components, two metal machined pieces that move within each other. The outer metal piece attaches to the upper A" arm or suspension component. The inner metal piece bolts to the chassis, this component may have a magnetic property. Sandwiched in between these two is a variably compressible donut or c-shaped piece that can vary the compressibility via magneto-rheological solution. The upper suspension component (a-arm etc.) is bound to a triangular metal bracket, with a bushing on each apex of the bracket. By varying the compressibility of each bushing or independently, the toe-in, castor and camber can be adjusted by the user to adjust ride properties to their preference. With adjustable shocks (MR), the ride can further be tailored to the drivers individual preference. With increasing one rearward bushing in stiffness, the weight of the car may displace the suspension forward some distance (1-5mm) thus changing the driving dynamic.
