Abstract

A step motor controller and its control method for the combined meter panel of car feature that the microcontroller is used for acquiring and processing the signals about water temp, fuel oil, voltage, machine oil pressure, air pressure, speed, etc and the step motors are directly controlled to point the working state of car. Said controller is composed of two main control chips, a memory chip, several step motors, buzzer, several alarm LEDs, LCD and UART.

Description

technical field [0001] The stepping motor controller and the control mode of the automobile combination meter of the present invention are a combination meter that uses a microcontroller to collect and process signals and directly controls the stepping motor to indicate the working state of the car. Its structure is suitable for trucks, passenger cars, cars, Motor vehicles, etc., are technically applicable to various types of vehicles. Background technique [0002] At present, domestic automobile instruments mainly adopt traditional mechanical structures, and in a small number of electronic instruments, cross coils are mainly used to drive pointers to indicate the working status of automobiles. The traditional mechanical structure instrument has disadvantages such as high cost, unstable performance, complex structure, and unattractive appearance; while some domestic electronic instruments using the cross coil method have low indication accuracy, easy to accumulate errors, an...
