Instant Mileage Assistance (IMA) in a Geared Two Wheeler

The Instant Mileage Assistance (IMA), as the name indicates, is a system to guide the vehicle users to realize maximum fuel economy (mileage). This system is targeted to provide users with instantaneous mileage indication depending on the current driving pattern, correct gear operating zone (in case of a geared vehicle) through gear up/down shift assist indication and the accurate distance the vehicle can travel before the fuel tank is empty, thereby assisting the user in harnessing maximum fuel economy the vehicle can deliver and also safely reach the next refilling station. The instantaneous mileage is calculated by mapping the distance travelled by the vehicle and the respective amount of fuel consumed, during a particular period of time, and is displayed using an instrument cluster.

Optimization of Damping Characteristics for Two Wheelers

In developing countries roads have a mix of high undulations as well as smooth and flat surfaces on highways. And also two wheelers are used for commuting with one or two people rather than for sport. A variety of spring characteristics are required to maintain the ride height for solo and doubles and wide variety of damping characteristics are required for various road conditions, loading conditions and speeds to achieve desired ride and handling characteristics. The spring and damper characteristics that are desired for good ride comfort will results in poor handling at high speeds. Achieving a very good level of ride comfort on rough and smooth terrains combined with an equally good level of handling with various loading conditions in the speed range of 20 to 120 Kmph is a highly challenging task. So most of the two wheelers are tuned for one loading case (solo or doubles) and either for ride comfort or handling with compromise on the other.
