Platformized vehicle body control framework system

Abstract

The invention discloses a platformized vehicle body control framework system which comprises adjustment of a vehicle body framework, construction of a vehicle body control platform and construction ofa vehicle body bus communication platform. The adjusted vehicle body framework comprises a vehicle body control box, a wireless receiving module, a ripple window anti-pinching module and an engine antitheft system module. A vehicle body CAN bus, a power CAN bus, an entertainment CAN bus, a new energy CAN bus and a chassis CAN bus interactively construct the vehicle body bus communication platformthrough an independent gateway. A keyless entry system, the wireless receiving module and the ripple window anti-pinching module of the vehicle body framework are all connected with the vehicle bodycontrol box through the vehicle body CAN bus. All control functional modules, such as vehicle backing radar, a rainfall sensor, front parking radar, atmosphere lamps, running water steering lamps andthe engine antitheft system module of a vehicle body jointly construct the vehicle body control platform. The vehicle backing radar, the rainfall sensor, the front parking radar, the atmosphere lamps,the running water steering lamps and the engine antitheft system module are connected with the vehicle body control box through an LAN bus.

Description

technical field [0001] The invention relates to a body control framework of a vehicle electronic control system. Background technique [0002] Joint venture models (such as Ford, Volkswagen, etc.) will develop a platform-based function & network architecture system. After the development is completed, multiple models will share the components under the same architecture system. In order to achieve the following goals: 1) Saving human resources of the main engine factory: multiple models are developed at one time, and subsequent models only need to be calibrated; 2) High reliability: Since the parts have been verified and verified in the first development Improvement, the reliability will be greatly improved in the continued use of the project; 3) Reduce the development cost of parts: due to the use of multiple models, the usage of parts will be greatly improved, and the price will also have a greater discount.

AI Technical Summary

Problems solved by technology

The traditional automotive SUV platform using this body control system architecture system has the following problems: 1) poor versatility: the body control components are less common among various projects; 2) powertrain suppliers are strong: some engine ECUs on the body CAN, The signal of the gearbox TCU varies greatly on different models

3) Function non-allocation aging: the distribution methods of each function are quite different, and the integration degree is not high

4) Shortage of human resources: multiple projects develop the same type of products at the same time, and human resources are repeatedly invested; 5) Reliability is difficult to guarantee: due to the short cycle of some projects, some newly developed body parts will expose problems in the initial stage of project production
