Automobile electronic control unit (ECU) and sensor connecting system and method

Abstract

The invention provides an automobile control unit (ECU) and sensor connecting system and method. An ECU battery module and a sensor module are mutually independent and are in communication through a communication network module; the ECU battery module internally integrates a plurality of first ECUs and a plurality of second ECUs, and the first ECUs and the second ECUs form the master-slave backuprelation; and the sensor module internally integrates a plurality of sensors, each sensor is connected with an executor, and each sensor and the corresponding executor cooperate jointly to drive partsof an automobile to operate. The problems, generated by hundreds of the ECUs of the automobile, of complex development, management, testing and maintenance cost, and the problem that an over-the-airtechnology (OTA) is inconvenient due to a Bug generated in ECU software can be solved, a large number of wire harnesses are prevented from being adopted to be interconnected, the cost is lowered, andsystem expansion and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a system and method for connecting an automotive electronic ECU and a sensor. Background technique [0002] Second-hand car control by wire is a technological trend. Mid-level cars basically have 30 ECU (Electronic Control Unit) electronic control units, also known as "driving computers", and high-end cars have up to hundreds of ECUs. So many ECUs involve complex development, management, testing, and maintenance costs; ECUx software bugs are not convenient for OTA (Over-the-Air Technology), that is, space download technology; a large number of wire harnesses are used in the existing technology to interconnect ECUs and sensors. One-to-one interconnection increases the cost, so a structure is needed to change this unfavorable situation. [0003] The prior art related to this application is the patent document CN103158757B, which discloses an integrated steering and ...
