Method for implementing electronic control domain system of whole vehicle

Abstract

The invention discloses a method for implementing an electric control domain system of a whole vehicle. The method comprises the steps that a signal processing module receives at least one sensor signal used for motor control and inputs the at least one sensor signal into an algorithm module; the algorithm module determines the current state of the vehicle according to the at least one sensor signal, estimates the state of the vehicle at the next moment, and obtains a control instruction according to the current state of the vehicle and the state of the vehicle at the next moment, wherein thecontrol instruction carries a motor identifier; and an instruction output module sends the control instruction to a driver corresponding to the motor identifier according to the motor identifier so asto enable the driver to drive the motor. According to the technical scheme of the invention, the network architecture of controllers of the whole vehicle can be simplified, the number of the controllers on the whole vehicle is greatly reduced, and the development period of the whole vehicle is shortened.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicles, and in particular to a method for implementing a vehicle electronic control domain system. Background technique [0002] The development and application space of automotive domain controllers is very broad. At present, there are a large number of scholars at home and abroad studying domain controllers. However, almost all domain controllers are divided according to functions: the upper layer of multiple controllers that implement the same type of function is added. A domain controller, which integrates the signals of all lower-level controllers to realize some system functions during driving. However, this top-down division method does not essentially simplify the architecture of the vehicle control system, but also increases the number of vehicle control units. If the layout of the vehicle controller unit breaks the conventional division of chassis, power, and body area, ...

Problems solved by technology

This makes it necessary to consider the layout of many motors during the development stage of the vehicle, which prolongs the development cycle

Moreover, the performance and EMC performance of motors from different suppliers are different, which will affect the mass production quality of the final vehicle, which not only increases the development cycle, but also introduces great quality risks.
