Modern cars have a lot of features and electronic system which causes the driver in dangerous driving Situation. one of such system has the task to measure and control the pressure of tyre that is automated tyredpressure system. This system will help to maintain the pressure in the tyre. The idea of building this Automatic Braking & self-Tyre inflation" was at aimed at different aspects but at the Same time made sureit was even Budget friendly, the aspects that we Aimed is the tyre its life. the impact of it on the fuel economy of vehicle and the safety of aspects. Is hold during Braking with ABS, low Braking initial speed Cause the brake pressure in long time. The why because there is a extending application time of brake pressure & response time of solenoid valve. this paper will help to maintenance Vehicles handling Characteristics.
