The invention provides a control method and a control system for transmission shaft excitation. The control method comprises the steps of obtaining a first variable quantity; wherein the first variable quantity is the variable quantity of the distance between the rear axle and the frame. And then determining the target adjusting quantity according to a first corresponding relation between the target adjusting quantity and the first variable quantity. And finally, adjusting the height of the intermediate bearing bracket by using the target adjusting quantity, so that the transmission shaft angle corresponding to the adjusted height of the intermediate bearing bracket is not greater than a preset angle threshold. Therefore, by adjusting the height of the middle bearing bracket and controlling the angle of the transmission shaft corresponding to the height of the middle bearing bracket, the alternating load of the transmission shaft is prevented from being increased, so that the vehicle shaking amplitude under the heavy-load uphill working condition is reduced to a certain extent, and the comfort of the vehicle and the user experience are improved.

    本申请提供了一种传动轴激励的控制方法及控制系统。控制方法包括:获取第一变化量。其中,第一变化量为后桥与车架距离的变化量。然后根据目标调节量与第一变化量的第一对应关系,确定目标调节量。最后利用目标调节量调节中间轴承托架高度,使调整后的中间轴承托架高度对应的传动轴角度不大于预设角度阈值。如此,通过调节中间轴承托架高度,控制中间轴承托架高度对应的传动轴角度,避免传动轴的交变载荷量增加,从而在一定程度上降低了重载上坡工况下车辆抖动幅度,提高了车辆的舒适性和用户体验感。
