Rollover prevention plays important role on instability of the vehicle. About 35% of accidents are caused due to rollover. Therefore, this brings a need to prevent accidents caused by rollover of vehicles. So, this system prevents the eventual rollover of the vehicle by a method of counter steering mechanism which turns or moves the vehicle in the direction where an eventual rollover is occurring by applying a physical principle of neutral equilibrium which is displacing an object while not changing the position of its center of gravity. Counter steering brings the vehicle into a neutral equilibrium state thus avoiding the rollover. The rollover is sensed by the MPU-6050 accelerometer cum gyroscope sensor which detects the roll angle, roll acceleration of the vehicle. The programming is done for the ATMEGA controller using Arduino IDE software for continuous monitoring of roll angle and roll acceleration of the vehicle. When the roll acceleration of the roll angle exceeds the rollover threshold value calculated by mathematical modeling, the controller sends the control signal through the H-bridge which changes the direction of the motor to turn the vehicle on the same side of the rollover which drives the ring gear on the steering column to create an effect of counter steer thus maintaining a neutral equilibrium and bringing the vehicle back to the ground and avoiding the rollover.
