Acceleration sensor simulation method applied to IBC system

The embodiment of the invention discloses an acceleration sensor simulation method applied to an IBC system, and the method comprises the steps: obtaining vehicle signals of a controller in a vehicle at all moments through a CAN bus under the condition that the vehicle runs on a ramp, and obtaining the angular speeds of wheels at all moments through a wheel speed sensor; calculating the vehicle speed and the vehicle acceleration along the ramp at each moment according to the wheel angular velocity at each moment; calculating the ramp resistance at each moment in real time according to the vehicle parameters corresponding to the vehicle signal at each moment, the wheel angular velocity and the vehicle speed and the vehicle acceleration along the ramp: decomposing the vehicle acceleration along the ramp at each moment according to the ramp resistance at each moment to obtain the vehicle acceleration along the horizontal direction and the vertical direction at each moment; the function of the acceleration sensor
