Vehicle body controller based on functional safety

The utility model discloses a vehicle body controller based on functional safety. The vehicle body controller comprises a main MCU module, a first input signal processing module, a main output controland detection module, a functional safety control module, a functional safety output driving module, a second input signal processing module and a power supply module. Through the double-MCU controltechnical scheme of the main MCU module and the functional safety control module, when the main MCU module breaks down, low-voltage power supply of the whole vehicle, a windscreen wiper, a brake lamp,a dipped headlight, a steering lamp, a position lamp and a passenger door are controlled through the functional safety control module, and the safety of the whole vehicle in the running process is ensured. 本实用新型公开了一种基于功能安全的车身控制器，包括主MCU模块、第一输入信号处理模块、主输出控制及检测模块、功能安全控制模块、功能安全输出驱动模块、第二输入信号处理模块和电源供电模块。本实用新型通过主MCU模块和功能安全控制模块的双MCU控制技术方案，实现主MCU模块发生故障时，通过功能安全控制模块实现对整车低压供电、雨刮器、制动灯、近光灯、转向灯、位置灯以及乘客门的控制，确保了整车运行时的安全性。
