The following is an example in which the first speed threshold is 5 km/h and the second speed threshold is 60 km/h:
when a vehicle speed signal received by the vehicle body controller 6 from the vehicle body electronic stabilizing system 15 is accelerated from 0 km/h and the vehicle speed is greater than 5 km/h, the vehicle body controller 6 determines the closing conditions of the left front door, the right front door, the left rear door and the right rear door through the left front door state switch 5, the right front door state switch 4, the left rear door state switch 3 and the right rear door state switch 2, if any one or more of the four doors are opened, the vehicle body controller 6 determines that the vehicle is opened and the vehicle starts to run, at this moment, the vehicle body controller 6 considers that the condition of a first dangerous running state is met, the vehicle body controller 6 triggers the door opening speed limiting function, and the CAN signal of 'dangerous driving 1' is sent to the vehicle body electronic stabilizing system 15, the combination instrument 16 and the engine electronic control unit 17. The vehicle body electronic stabilizing system 15 receives the CAN signal of the dangerous driving 1 sent by the vehicle body controller 6, and the vehicle body electronic stabilizing system 15 judges the vehicle speed in real time and controls the vehicle speed to be not higher than 60 km/h.
The electronic engine control unit 17 receives the CAN signal of "dangerous driving 1" from the vehicle body controller 6, the electronic engine control unit 17 limits the accelerator opening to below 30% through internal logic, and controls the engine system to work according to 30% if the driver steps on the accelerator to a depth exceeding 30%, so as to control the output power of the engine and reduce the braking energy required by the electronic vehicle body stabilizing system 15.
The combination meter 16 receives the CAN signal of the dangerous driving 1 sent by the vehicle body controller 6, the combination meter 16 gives an audible and visual alarm to remind a user, and the audible and visual alarm comprises: the combination meter 16 is used for carrying out text reminding on 'the vehicle door is opened and the speed is limited', and meanwhile, the combination meter 16 simulates to send out an emergency alarm sound to remind a user.

The vehicle body electronic stabilizing system 15 receives the CAN signal of the dangerous driving 2 sent by the vehicle body controller 6, the vehicle body electronic stabilizing system 15 decelerates the vehicle according to the calibrated brake pressure, judges the vehicle speed in real time and controls the vehicle to accelerate at-6 m/S2(the deceleration of the door-opening deceleration function of the vehicle can be calibrated, and the acceleration is-6 m/S in the embodiment2) And decelerating until the vehicle speed reaches below 60 km/h, and controlling the vehicle speed to be not higher than 60 km/h.
The electronic engine control unit 17 receives a CAN signal of 'dangerous driving 2' sent by the vehicle body controller 6, the electronic engine control unit 17 limits the opening of an accelerator to be below 50% through internal logic, and controls an engine system to work according to 50% if the driver steps on the accelerator to exceed 50%, so as to control the output power of the engine and reduce the braking energy required by the electronic vehicle body stabilizing system 15, but the stability of the vehicle and the uncertainty of road conditions during high-speed driving are considered, so that the output power of the engine is higher than the door opening speed limiting function.
After the vehicle body controller 6 informs the vehicle body electronic stabilization system 15 to decelerate the vehicle, the vehicle body controller 6 will drive the left front steering lamp 11, the left rear steering lamp 12, the right front steering lamp 13 and the right rear steering lamp 14 to flash at the same time, and the flashing frequency is according to the frequency of emergency alarm.
The combination meter 16 receives the CAN signal of the 'dangerous driving 2' sent by the vehicle body controller 6, the combination meter 16 gives an audible and visual alarm to remind a user, and the audible and visual alarm comprises: the combination instrument 16 is used for carrying out text reminding on 'opening of a vehicle door and passive deceleration', and meanwhile, the combination instrument 16 simulates and sends out an emergency alarm sound to remind a user.
