1.1 literature survey as a driver, there are times when every seat is taken and the boot is crammed full. aside from a generally reduced performance and the need to drive slightly differently with a heavier load, this is not something to which one typically gives much thought. maybe there will be fewer miles to the gallon and stopping distances will be increased, but the thought that one might actually be overloading the car or need to change tyre pressures is not something that crosses most drivers' minds. it should. in fact, it's rather obvious when you think about it. while commercial vans and vehicles have strict loading weights that are noted somewhere prominent on the vehicle, day-to-day consumer cars do not. do you know your car maximum load and how would you go about measuring it? this is the issue that engineers at international automotive supplier continental have been mulling over for some time and it now believes it has a solution. as part of on-going developments it is developing and widening the range of functions available to its tyre pressure sensors. overloading is the scourge of fleets. it creates an unsafe vehicle that can cause injuries and fatalities, which will invariably result in a lawsuit. statistics show that overloaded and improperly loaded trucks are among the leading causes of truck accidents. overloading is a growing industry problem. one reason is that more fleets are seeking to lower acquisition costs by selecting lower-gvw trucks. although this "strategy" saves money on the front end, the inevitable overloading increases operating costs on the back end. a corollary reason for spec'ing lower-gvw trucks is to avoid dot regulations, which require drivers to have a commercial driver's license (cdl) to operate vehicles greater than 26,001-lbs. gvw. also, with higher fuel costs, carrying larger loads results in fewer trips, increasing per-trip profitability   1.2 problem formulation in realizing and perfecting the control of loading in vehicle concept: the total weight of the car, including its passengers and cargo may be within the load limit of the tires when you start the trip. but since tires lose air while on the road, a point may be reached when the tire pressure is too low for the total original weight of the car. in that case, the car is considered overloaded. to avoid this scenario, you can avail of certain safety devices which can be installed into the tires and which monitors the tire pressure in real time. using the chart given by the vendor of the tire, the driver can ascertain if his vehicle is overloaded and take the proper measure to remedy the situation. overloading makes driving a hazard for everything and everyone involved. the driver himself will find the wheels sticky; the suspension of the car will sag and eventually give out with repeated overloading. the clutch will also be adversely affected by too much weight in the vehicle. because of the constant danger of blowing the tires, overloading is a potential hazard for other motorists on the road. overloaded vehicles will also be harder to get to a full stop. this may impair the ability of the driver to bring the car or truck to stop in time to prevent an accident from happening. the following scientific and technological (s&t) objectives have been established to design prototype test and validate the control of loading in vehicle systems: o to increase a vehicle's service and operating expenses. o to stop failure of equipment, personal injuries, and possible liabilities. o to stop the premature wear-and-tear on tires and suspension components. o to increase handling capability. o to decrease braking distance. o to stop the roll-over of vehicle while taking a sudden turn.   2. methodology 2.1 – basic steps of formation step – 1: in this project we choose a printed circuit board (pcb) and equip it with a comparator, analog to digital converter (adc), a microcontroller and a driveric as shown in fig.1 & fig. 2. fig.1 fig.2 step-2 secondly we attach a small electric vehicle with the printed circuit board. the vehicles of the wheel are driven by two motors respectively. fig.3 fig. 4 step -3 now we take a digital weighing scale. this is used for measuring the applied load. the digital weighing scale is being attached with the printed circuit board. fig.5 step -4 our next step is to connect weight sensor to the weighing scale. fig.6 fig.7 step -5 our next is the programming part. in this part a program is compiled in the pcb. and specifying the limit of the load after which the motor will stop its motion. fig.8 step-6 now our electric motor vehicle is ready for its operation. the vehicle is started and the load is applied gradually over the weight sensor. after the specified weight load limit is reached then the vehicle’s motion stops. 2.2 schematic arrangement of model flexi force sensor electric motor vehicle
