Abstract

The invention discloses a driving control method and system, and the method comprises the steps that a micro-control unit transmits to-be-transmitted data to a driving chip through a microsecond bus, and the to-be-transmitted data comprises the operation state information and driving state information of the micro-control unit; and the driving chip receives data to be transmitted and stores the data to be transmitted in the register. The microsecond bus is used for transmitting the driving signal, so that the technical problems that too many driving chip pins are occupied and are easily interfered by EMC due to the fact that I / O driving control is used in the prior art are solved, and the technical effects that the driving chip pins are saved, chip integration is improved, system space is saved, and the EMC performance and safety of a driving system are improved are achieved; and the possibility of driving misoperation caused by the abnormal driving state is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of drive control, and in particular, to a drive control method and system. Background technique [0002] In the existing drive mode, the drive control uses the I / O (input / output) control mode. This drive mode uses many pins. In functional safety, driver abnormality is an unacceptable risk, and occupying more pins will make the driver chip suffer from EMC interference. Contents of the invention [0003] The present invention provides a drive control method and system, which solves the technical problems of using I / O drive control in the prior art that occupy too many pins of a drive chip and are susceptible to EMC interference. [0004] An embodiment of the present invention provides a driving control method, and the driving control method includes: [0005] The micro control unit transmits the data to be transmitted to the driver chip through the microsecond bus, wherein the dat...
