Abstract

The invention relates to a new energy vehicle domain controller safety monitoring chip program updating method and system. The updating method comprises the following steps that A, an MPU of a domain controller receives a safety monitoring chip updating file; B, the MCU of the domain controller processes the security monitoring chip update file; and C, the security monitoring chip of the domain controller is upgraded. According to the updating method, the security monitoring chip in the domain controller can be upgraded, and the upgrading mode is simple, convenient and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicle domain controllers, and in particular relates to a program update technology for a security monitoring chip of a new energy vehicle domain controller. Background technique [0002] At present, the electronic and electrical architecture of new energy vehicles is gradually shifting from a distributed control architecture to an integrated domain control architecture, and the complexity of domain controller product functions is also becoming more and more complex due to the continuous improvement of integration. The computing core of the domain controller is usually composed of a powerful multi-core processor plus a security monitoring processor and an MPU processor. In addition to the conventional common data I / O and analog signal input and output functional interfaces, the external interface resources also have abundant Internal / external communication interface, such as common internal co...
