This invention relates to the development of an Android Based Hybrid Electric Smart Car
named as PIXY (see figure 1), which combines an electric propulsion system with a
conventional internal combustion-engine (ICE). PIXY is a light weight small hybrid electric car
with a small petrol internal combustion engine. Petrol engine is used to fulfill more power
requirement when needed and it can also be used as an alternative when battery backup is not
enough. PIXY is a two seater smart car which is developed to meet the need of commuters, city
travelers and disable persons. Auto Pilot Mode (APM) is extremely helpful for disable persons in
traffic jam or slow moving conditions.
Software controlled integrated Dual Power
Transmission Switch (DPTS) is developed to
switch or select the power/fuel type between
Electric and Petrol. A GUI based Smart Car
Control System (SCCS) (see figure 2) is
developed, which can be easily installed on any
Android based smart phone or tablet. SCCS can
communicate with DPTS, Door opening system,
GPS navigation system and music system of
PIXY through Bluetooth. The smart phone or
tablet can be easily mounted on the front
Figure 1 Pixy Smart Car
dashboard of PIXY. The commuter can easily select the buttons on touch screen of smart phone
to switch the desired power source either electric or petrol, moreover other functions can also be
operated like opening/closing the doors, music player, GPS navigation etc.

PRIOR ART AND PROBLEM TO BE SOLVED
The smart cars already available in the market does not have duel power mode, which can be
switched from Battery to Petrol and vice versa through Android based smart phone or tablet, they
are either Petrol or Battery and smart features are not available like Gull Wing Doors, Auto Pilot
Mode and RFID system to access. The car which I developed named as PIXY, have hybrid
solution for Battery and Petrol. This is electric car, which combines an electric propulsion system
with a conventional internal combustion engine (ICE). PIXY is a light weight small hybrid
electric car with a small petrol internal combustion engine. Petrol engine is used to fulfill more
power requirement when needed and it can also be used as an alternative when battery backup is
not enough. PIXY is a two seater smart car which is developed to meet the need of commuters,
city travelers and disable persons. Auto Pilot Mode (APM) is extremely helpful for disable
persons in traffic jam or slow moving conditions. PIXY having Gull Wing doors which is
operated through Smart phone or manual push buttons. PIXY having RFID system to open and
close the doors through RFID Smart Card, these features make this car smart and unique.
