This hydromechanical automatic transmission provides hydraulic regenerative braking for cars, trucks and buses with an approx. 40% improvement in mpg at a total vehicle cost less than the equivalent conventional vehicle. It provides 60 separate forward gear ratios (approaching continuously variable).
It consists of 8 fixed displacement hydraulic pump/motors,
This type of hill start assist has been developed for a manually driven car and assists the driver to negotiate an inclined terrain by retaining the brakes even after the driver removes his foot from the brake pedal. The brake force gradually decreases depending on the rate of acceleration determined by the clutch position.
Though all engines produces power, not all of them are fully utilised for the vehicle's performance. Nearly half of thus produced power is wasted. The torque produced above the mean torque line of the engine is considered to be excess energy which is wasted.
Usually only 10-16% of the fuel energy is used to drive the vehicle to overcome the air resistance and air drag. Regenerative shock absorbers have the ability to continuously recover a vehicle's vibration energy that is otherwise dissipated due to road irregularities, vehicles acceleration and braking, further using this energy for better suspension control.
Having human staff at night or in remote rural areas poses several practical difficulties, including health hazards, security problems and also it causes disputes in quantity and payment which lead to crowding at fuel stations. Regardless of the transportation method or type of fuel (electricity or gasoline), future vehicles will still regularly need fuel-filling.
To design a prototype of an accident avoiding electronically controlled safety system to provide safety at high speed from frontal collision. By designing electronic systems we are going to prevent the vehicles from accident by detecting the distance of any obstacle while we are following any other vehicle.
The main aim of the project is to prevent accidents that is increasing day by day on the roads. The GPS with micro controller detects the accident black spots that has been preloaded in the memory matching with current latitudes and longitudes.
The Jack Rabbit series of personal transportation vehicles are each built using various configurations of bicycle frames, wrapped in a fitted canvas skin; making it something akin to a bi-plane without wings.
The idea is to replace the standard big car with something you can fit 30 of across your standard city main street. Thus reducing traffic congestion,
The invention concerns a land vehicle positioning system (called LVPS) used in the land transporting mobile machines, such as cars, trucks, buses, motorcycles, trains, bicycles for navigation and determining the current geographic position of the vehicle.
There are different positioning systems based on the receipt of radio signals from different transmitters such as satellites (GPS, Galileo, COMPASS), beacons (LPE),
We replace conventional spark plug by laser ignition. Since spark plug are less efficient, we have chosen a laser ignition system. Laser has many advantages over spark. It wil help to increase efficiency of the engine.
Why Laser Ignition....
Regulations on NOx emissions are pushing us toward leaner air/fuel ratios (higher ratio of air to fuel).
