Design an intelligent car carrier instrument system with voice function to strength the assistant driving function. The system adopts SPCE061A single chip as the control core, together with sensor unit、display/keyboard、reproduce and other parts . At work, the system displays the data detected by sensor on the LCD and adopts SACM_A2000 voice algorithms to begin to broadcast the rate of the vehicle、the oil mass of the tank 、the temperature of the cooling liquid and other key parameters, when the driver presses the bottom of the voice broadcast. To enhance the effectiveness of the broadcast parameters, firstly, broadcast the initial voice of the parameters; then, detect and broadcast the parameters in the software design. Simulation results show that the system with the advan-tage of reasonably practicable design good real-time parameters and clear voice. And the system with low-cost and anti-interference can widely use in various types of vehicles Instruments.
