Embodiment Construction

[0071] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0072] If classified according to the role of each part of the car, it can be divided into several domains. For example, based on Bosch's classic five-domain classification, the vehicle is divided into power domain, chassis domain, cockpit domain / intelligent information domain, automatic driving domain and body domain. An embodiment of the present invention provides a chassis domain controller, figure 1 For a schematic structural diagram of a chassis domain controller provided by an embodiment of the present inve...

Abstract

The embodiment of the invention discloses a chassis domain controller. The chassis domain controller comprises a power management module, a multi-core microprocessor minimum system module, a CAN-FD receiving and transmitting module, a PWM signal processing module, a switching signal processing module, an analog signal processing module, a multi-path intelligent low-side driving module, a current closed-loop driving module, an intelligent high-side driving module, a storage module, an acceleration sensor processing module, and a PSI5 signal processing module. The power supply management module is connected with the multi-core microprocessor minimum system module, the multi-core microprocessor minimum system module is connected with the other modules, and the multi-core microprocessor minimum system module achieves the purpose of controlling the chassis area of the vehicle by controlling the modules. And the power management module is used for converting the voltage provided by the storage battery into the voltage required by each module. According to the embodiment of the invention, the problems of system safety and high controller cost of a traditional chassis domain controller are solved.

Description

technical field [0001] The embodiment of the present invention relates to the chassis domain control technology, in particular to a chassis domain controller. Background technique [0002] As passenger car users have higher and higher requirements for the comfort and safety of passenger cars, the number of various controllers in the car is also increasing. [0003] The current chassis domain control is controlled by multiple controllers, which are subdivided from a functional perspective to provide computing power for various operations. Each controller is single purpose. [0004] However, there are some problems in this architecture. Since the current chassis domain control is obtained by connecting multiple controllers, it is difficult to ensure system security, and the total cost of multiple controllers is relatively high. In the context of increasing computing power, the number of controllers is increasing, and the resulting cost problem needs to be solved urgently. ...
