Advanced Smart Road Traffic System and Automotive Patents of Electric, Hydraulic and Hybrid Cars

Only about 15% of the energy from the fuel you put in your tank gets used to move your car down the road or run useful accessories, such as air conditioning. The rest of the energy is lost to engine and drive line inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous. With an Electric Passenger Car it costs just €1.60 per 100kms with regenerative brakes more performance than with petrol at €17.00 per 100kms.

The main objective of our advanced vehicle powertrain hybridization is to simultaneously improve the fuel/energy consumption and environment pollutants impact (Eco-score) without decreasing the vehicle performances and other user satisfaction criteria. Based on our simulation model SMART DRIVE, one can evaluate the performances, the emissions and then the Ecoscore and the user satisfaction for different driving scenarios. To establish a rationale methodology for assessing the eco-efficiency character, we adopt a multidisciplinary optimization approach while minimizing / maximizing both Eco-score and user satisfaction objective functions. The proposed approach is then used to establish a comparison between HEV (hybrid electric vehicle) and HHV (hybrid hydraulic vehicle) configuration by highlighting the effect of different energy storage systems (batteries, ultra capacitors, hydraulic system), mechanical and electric components sizes upon the optimized HEV design. The selected application is the comparison of different mild parallel hybrid buses. Results show that the hybrid electric buses using ultra capacitors have almost the same performances as those using batteries, while the HHV technology can compete with HEV because of the hydraulic components low cost and recyclability if possibly using of water as motor/pump fluid.

AUTOMATED POWER SYSTEM FOR HYBRID AND ELECTRIC CARS (EV, HEV & HHV) Patent BG 65421

The automated power system regenerates the mechanical energy when a car stops that has a reversible electric machine. It helps achieve highly efficient recuperation of the kinetic energy when the carstops thanks to the gear-box, which increases the revolutions of the electric machine working as an electric generator when stopping. The system is energy saving and controlled by smart device. It is driven by a reversible electric machine (1) fed by an electric accumulator (2). The machine (1) is coupled to a gear-box (3) converting the motion and transmitting it to at least one wheel (4) of the car, which is controlled by a car driving block (5) that receives signals from an accelerator pedal (6) and by a car breaking block (7) that receives signals from a brake pedal (8). Two actuating mechanisms (9and 10) connected to the driving block (5) as well as other two actuating mechanisms (11 and 12) connected to the breaking block (7) are provided for regulating, respectively of the electric machine (1) as a motor and the gear-box (3) converting and transmitting the motion to at least one drive wheel (4), and vice versa û of the electric machine (1) as an electric generator and the gear-box (3) converting and transmitting the motion from at least one brake wheel (4) to the machine (1).

HYDRAULIC DRIVE-AND-BRAKE SYSTEM FOR VEHICLES (HHV) Patent BG 65480

The hydraulic drive-and-brake system for vehicles comprises at least one wheel (1) driven by at least one reversible hydraulic machine (2) charged by a hydraulic accumulator (3). The axle of the wheel (1) is coupled through a variational reducer/multiplier of the speed to a hydraulic machine (2), whose two-direction regulating valve (5) is controlled by a unit (6) that regulates the machine (2) as a motor and the variational reducer/multiplier (4) transforming and transmitting the motion to at least one drive wheel , and vice versa û the machine (2) as a hydraulic pump and the variational reducer/multiplier (4) transforming and transmitting the motion from at least one brake wheel to the machine (2) working as a hydraulic pump. The control of the hydraulic drive-and-brake system is assisted by an optimizing programmable smart unit (14). The unit inputs are connected to the outputs of a pick-up (15) for individual monitoring of the motion of each wheel and a pick-up (16) for the level of charging of the hydraulic accumulator (3), and the outputs thereof are connected to the units (6 and 8), respectively for driving and braking. The unit (14) makes it possible to save much energy when driving in urban areas in return for restoring the kinetic energy of the stopping vehicle

According to this patented invention number of hydraulic-hybrid car are developing. Hydra-Drive vehicle power trains were aimed at delivery applications that involve short-haul travel with many starts and stops — great for recovering energy with regenerative braking. A Hydra-Drive production package should cost less than battery technology. Unlike today's electric hybrids, hydraulic technology completely decouples the engine from the driveline, so the engine (which now can be smaller) always runs at its most efficient point in charging hydraulic accumulators. In many ways, these hydraulic hybrids conceptually resemble their electric hybrid cousins. Only in this case, energy storage takes place not in a electric battery but in high-pressure hydraulic accumulators usually charged in excess of 3,000 psi.

Design concepts for hydraulic hybrids vary, but typically the car’s diesel or gas engine powers a hydraulic pump motor, which charges that high-pressure accumulator. The accumulator, in turn, drives one or more additional pump motors connected to the wheels. A second lower pressure accumulator typically completes the hydraulic circuit. Depending on the design, there may be one pump motor to drive a pair of wheels through a differential or one pump motor per wheel for an all-wheel-drive version with independent torque control. During braking, the pump motors on the wheels reverse themselves, re-charging the accumulator and capturing energy that would otherwise be lost to heat.

The hydraulic hybrids now under development can communicate with modern engines and do have some electronic controls. Yet in their purest form, they don’t really need any electronics to function. Hydraulic hybrid vehicles aren’t exactly news to everyone. Operators of truck fleets have recently taken an interest.

The simulation results showed 5 seat car with hydraulic drive train was about 95 percent efficient, once you add in the vehicle’s regenerative braking energy. That efficiency is only about 4 percent better than a conventional mechanical drive train. Yet, thanks to the hybrid’s engine optimization and engine-off operations, total fuel conversion efficiency jumped from 19 percent with the traditional vehicle to 37 percent with the hydraulic hybrid.
