The invention discloses a dangerous driving early warning and braking system based on a multi-core heterogeneous chip, which comprises sensor equipment, the multi-core heterogeneous chip and an executing mechanism, the sensor equipment acquires physiological signals, body reaction signals and vehicle state information of a driver and transmits the physiological signals, the body reaction signals and the vehicle state information to the multi-core heterogeneous chip, and the multi-core heterogeneous chip processes the received information and controls the executing mechanism to execute the dangerous driving early warning and braking. And the execution mechanism gives an alarm or brakes according to the information processing result. According to the method, data from different sensors are effectively integrated, consistency explanation of the mental state of a driver is facilitated, and the false alarm or missed alarm phenomenon caused by a single method is greatly reduced; a multi-core heterogeneous chip is adopted for implementation, different tasks can be processed at the same time, different cores execute different tasks, the data processing efficiency is greatly improved, power consumption is reduced, and the number and cost of chips are reduced; the method has high expandability, and the FPGA can integrate different function IPs required by users, so that the purpose of expanding applications is achieved.
