The invention discloses a rearview mirror control system. The rearview mirror control system comprises a communication chip, an on-off detection circuit, a single chip microcomputer, a driving circuit, a current monitoring circuit and a motor; the communication chip is connected with the single chip microcomputer for transmitting a received communication signal to the single chip microcomputer; the on-off detection circuit is connected with the single chip microcomputer for transmitting a rearview mirror on-off signal to the single chip microcomputer; the current monitoring circuit is connected with the single chip microcomputer and the motor separately for feeding back the current signal of the motor to the single chip microcomputer in real time; and the driving motor is connected with the single chip microcomputer and the motor separately so as to drive the motor to work according to control of the single chip microcomputer. Therefore, the current signal of the motor, namely the current value in rotation of the motor, can be fed back to the single chip microcomputer in real time through the current detection circuit, and then the single chip microcomputer controls the driving circuit to further control the motor to rotate or stop according to the current value in rotation of the motor; and compared with the control system adopting a sensor, the control system adopting the current detection circuit is low in hardware cost, so that the hardware cost can be further lowered. In addition, the invention also discloses a rearview mirror control method with the above-mentioned effect.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a rearview mirror control method and system. Background technique [0002] As consumers and relevant government departments continue to increase their requirements for automotive safety, comfort, environmental protection, and reliability, electronic technology is becoming more and more important in automotive applications, and has become the most important for developing new models and improving automotive performance. Therefore, cars are becoming more and more electronic and intelligent. [0003] As an important part of the car body, the exterior rearview mirror needs to be folded or unfolded according to the user's requirements (rearview mirror switch, remote control key, etc.). The electronic control of folding or unfolding of the rearview mirror is generally realized by driving a DC motor through a controller. At present, there are mainly four schemes for controlling th...
