* Question
| What technical requirements do the automotive MCU application systems need to meet while implementing the measurement and control functions? |
* Answer
| Automotive microcontroller applications differ from general-purpose computer systems.The general-purpose computer system is mainly used for data processing, and requires large storage capacity, fast running speed, and strong versatility.The automotive single-chip application system mainly realizes the detection of various signals and the control of various components, and the functions are relatively simple, and do not require strong versatility.Therefore, the reliability is crucial for the automotive single-chip application system. Moreover, in the event of a failure of the automotive single-chip system, an emergency backup system can temporarily replace the automotive single-chip microcomputer to maintain the operation of the vehicle.Electromagnetic interference and voltage fluctuations generated by various electrical equipments will have a certain impact on the normal operation of the automotive single-chip system.Therefore, in order to make the automotive single-chip system work reliably and trouble-free, the following requirements must be met: 1 The temperature range is -40 to 125 0C.
(3) It has perfect input/output channel and real-time control capability. In order to detect and control the running process of the car, it needs to transmit a large amount of data and various types of signals. Therefore, the automotive single-chip system is required to have relatively complete analog and digital inputs./ Output channel. (4) Easy to operate and maintain The automotive single-chip system is installed in the car. The user is not a professional computer personnel. Therefore, the operating system and signal control system should be simple and clear, and easy to operate.In the event of a failure, the cause can be identified in a timely manner and quickly eliminated.And should leave a data interface, so that maintenance personnel can use the fault code reader to read the fault code from the single-chip system, which is convenient for maintenance.The reliability of the work of the automotive single-chip application system is guaranteed from the software. |
