What does the letter 'A' on the Haval H6 tachometer indicate?
1 Answers
Haval H6 tachometer displaying 'A' signifies that the intelligent start-stop system is activated and currently operational. The working principle of an automotive tachometer involves processing digital pulse signals received by the tachometer, which are then directly input into the CPU's counting port. The software calculates the rotational speed and corresponding needle position, after which the CPU's control port amplifies and drives the stepper motor to rotate clockwise or counterclockwise, indicating the respective RPM value (each step of the stepper motor moves just one-third of a degree). The Haval H6 is the flagship model under the Haval brand, positioned as an urban intelligent SUV, with body dimensions measuring 4640mm in length, 1825mm in width, and 1690mm in height.
