And when the vehicle body inclination angle is judged to be smaller than 0, the controller controls to reduce the front pressure and controls to increase the rear pressure according to the ratio of the vehicle body inclination angle to the corresponding preset auxiliary adjusting coefficient. In this case, the vehicle body inclination Angle Slope _ Angle is a negative number, the auxiliary adjustment coefficient for the Front pressure is B3, the value of B3 requires an absolute value greater than the inclination Angle Slope _ Angle, the ratio of the vehicle body inclination Angle Slope _ Angle to the preset auxiliary adjustment coefficient B3 is used as the compensation coefficient for the Front pressure compensation value at that time, the compensation coefficient is a negative number, and the Front pressure compensation value P _ Front _ Plus at that time is: the Front pressure P _ Front is added to the product of the Front pressure P _ Front and the compensation factor to reduce the Front pressure, which is expressed by the formula: p _ Front _ Plus ═ P _ Front (1+ Slope _ Angle/B3); the auxiliary adjusting coefficient for the rear pressure is B4, the value B4 requires the absolute value of the value Slope _ Angle smaller than the inclination Angle, the ratio of the vehicle body inclination Angle Slope _ Angle to the preset auxiliary adjusting coefficient B4 is used as the compensation coefficient of the rear pressure compensation value at the moment, and the product of the rear pressure P _ Back and the compensation coefficient is subtracted from the rear pressure P _ Back _ Plus at the moment, so that the rear pressure is increased, and the formula is represented as follows: p _ Back _ Plus ═ P _ Back ═ 1-Slope _ Angle/B4.
