Electric automatic driving automobile brake energy monitoring device and method

The invention provides an electric automatic driving automobile brake energy monitoring device conforming to function safety. The device comprises a main control module and a monitoring module, and ischaracterized in that the main control module comprises a brake control module, a safety deceleration monitoring module and a battery remaining capacity SOC monitoring module; the monitoring module comprises a main monitoring module, a current overcurrent monitoring module and a watchdog module. The requirement for functional safety can be met. Reasonable distribution of mechanical braking and regenerative braking is monitored, and unexpected insufficient braking force is prevented; when the automobile generates braking energy feedback, the residual electric quantity of the power supply battery is monitored, battery overcharge and instantaneous current overlarge are avoided, so that the automobile reaches a safe state in the braking process. 本发明创造提供了一种符合功能安全的电动自动驾驶汽车制动能量监控装置，包括主控模块和监控模块，所述主控模块包括制动控制模块、安全减速度监控模块、电
