1. WELCOME TO ALL PACE INSTITUTIONS and INTEGRATORS

2. Emerging Market Vehicle Project MCU-based SMART BRAKING SYSTEM (SBS)

3. In these days human life is becoming more and more valuable. Accidents are increasing day by day. Driver pre-occupation continues to increase This has lead to many revolutionary strides in automotive technology. A critical intervention is a MCU-based SMART braking system.

4. Automatic braking system using sensors is a highly sensitive braking system which works in coordination with existing braking system. This makes use of sensor arrays, signal conditioners, amplifiers, actuators & micro controller unit.

5. Obstacle Sensor arrays Amplifier Micro controller Deceleration braking Signal Conditioner

6. Sensor arrays

7. Three sensor arrays, capable of tilt and pan are placed at the front & rear bottom ends of the vehicle. The range of these sensor arrays would depend on maximum braking distance Sensor data would be processed for humps, depressions, approaching vehicles or any static or dynamic obstacles, road curvatures, etc The conditioned and amplified signals are received by the microcontroller.

8. The MCU processes these signals from the sensor arrays to decide whether to: –Decelerate the vehicle –Brake the vehicle or –Simply warn the driver –Or perform a hybrid action of all the above

9. Sensor arrays fitted at the rear of the vehicle will work in tandem with the sensors in the front. The pan and tilt of the sensor arrays is also controlled by a Cam-MCU operation

10. ADDITIONAL FEATURES: the brakes are made to apply gradually so that the speed of vehicle is reduced to less than half of its original speed in a very short time. By this, within the range of distance between two vehicles automatic braking is applied & time is obtained for the driver to turn the power steering to avoid the accident. A WARNING SIGNAL system may also be fitted along with this, so that the driver becomes conscious about the danger.

11. The array ranges are so designed that vehicle can be slowed down during humps. This can be a rotating sensor.

12. Perceived Merits 1. Designed to work with electronic ABS systems. 2. A hybrid dynamic system of braking acting on deceleration as well as on brakes 3.Wear and tear significantly reduced on all moving portions of the vehicle 4. Significantly increases mileage in Indian road & traffic conditions 5. Obvious advantages on highways

13. Example According to standard tests, a fatigued driver travelling at the rate of 60 km/h will traverse a distance of 52 m before stopping as the reaction time of the said driver is generally more than 2 seconds With the proposed braking system, the vehicle decelerates automatically at a faster rate resulting in lesser damage and in an accident free scenario.

14. Tasks and Challenges - each in semi-design stage Mechanical –Design of sensor array geometry –Cam mechanism for sensor pan and tilt –Modification of accelerating and braking mechanism Electronics –Design of range sensor arrays –Design of signal conditioners, amplifiers and MUX –Design of input and output drivers –Design of MCU – hardware & software
