Motor bus active rollover-prevention control test device

The invention provides a motor bus active rollover-prevention control test device and belongs to the field of motor bus active safety coefficient tests. The device is characterized in that digital signals of variables such as a bus speed, an acceleration, a suspension displacement are generated by a computer with a virtual motor bus system, and real sensor physical signals are simulated by a D/A conversion circuit through the digital signals, an active rollover-prevention control system collects the real sensor physical signals and makes an active rollover-prevention algorithm decision, the active rollover-prevention control system predicts whether the motor bus has a rollover danger at the next moment according to the driving state of the motor bus, if yes, a control signal of a suspension displacement adjusting device is output, the control signal is converted into a digital signal by an A/D conversion unit, and the digital signal is transmitted to the computer with the virtual motor bus system, so that the
