The electrical vehicle application each wheel is powered by different DC motors. The brush less DC is motor is to achieve to power the wheels at high accuracy with low power. In these type of vehicle there are several problems is faced during the speed maintain. During the speed of the wheels in vehicle is change in turning. Normally the time of the turning the vehicle wheels speed not because the inner wheel speed is minimum compare to the outer wheel. Electric vehicles make use of permanent-magnet (PM) synchronous traction motors for their high torque density and efficiency. Recent advances in traffic monitoring systems have made real-time traffic velocity data ubiquitously accessible for drivers. To control PM brushless DC motors, position and speed sensors are indispensable because the current should be controlled depending on the rotor position. However, these sensors are undesirable from standpoints of size, cost, maintenance, and reliability. There are different ways of approaching this problem, depending on the flux distribution. In our proposed we achieve control the speed in DC motor with specific speed during the turning time. Here we use the wavelet based differential control for maintain the speed of the each wheel by turning angle and steering angle of the vehicle.
