ARM Processor based Vehicle Safety System for Indian roads

After drunken driving, mobile phone usage is the leading cause of accidents around the world. Also, at sudden stoppages on cross roads or due to sudden obstructions on road, natural or otherwise the driver cannot anticipate back bumper and side collision. Also, low height railing or pavements in blind spots while parking may damage the vehicle. Costly mobile phone jammers while effective render emergency communication impossible. As alcohol detection and vehicle tracking system are successfully implemented we are proposing an essential vehicle safety kit which is absent in majority of the vehicles on Indian roads. Furthermore this can be an addition to the developing cognitive driver assistance system. The proposed system provides vehicle with safety features like SMS alert facility, blind spot detection and tail gating detector. The vehicle is equipped with ultrasonic sensors and a GSM modem interfaced with Nuvoton ARM cortex processor. The driver has access to a user interface consisting of LCD (128 x 64 pixels), a keypad and switching ports. The driver may access two modes of distance sensing with sensors located on left, right and rear of the car. A braking system is actuated in the parking mode if the distance measured from the sensors crosses the defined threshold. In the traffic mode the driver is alerted and can take preventive action. In case of an emergency the driver can send a text or call from the stored numbers in the memory using the keypad. To save time and to maintain the driver’s focus on the road a default text can be sent to a default number by a single key pad entry. Call service from the system eliminates the need of using the phone and prevents driver’s loss of focus. Further the freedom to choose the number and the corresponding message to be sent is available when the vehicle is at rest. The system thus prevents accidental damage to the vehicle and its passengers while eliminating the use of phone by the driver.
