The invention provides a semi-active suspension control method, a controller and an automobile. The method comprises the steps that whether semi-active suspension emergency braking control or semi-active suspension pre-braking control is triggered or not is judged; if the emergency braking control of the semi-active suspension is triggered, damping of an adjustable shock absorber of the semi-active suspension is controlled so as to restrain the forward tilting action of a vehicle body during emergency braking, and the adhesive force of a rear wheel is kept; if the pre-braking control of the semi-active suspension is triggered, the height of an adjustable spring of the semi-active suspension is controlled, so that a vehicle body is adjusted to be in a slight backward leaning state before emergency braking of the vehicle. 本发明提供了一种半主动悬架控制方法、控制器及汽车，上述的该方法包括：判断是否触发半主动悬架紧急制动控制或半主动悬架预制动控制；若触发半主动悬架紧急制动控制，对半主动悬架的可调减振器的阻尼进行控制，以抑制紧急制动时的车身前倾动作，并保持后轮附着力；若触发半主动悬架预制动控制，对半主动悬架的可调弹簧的高度进行控制，使车辆在紧急制动之前调整车身为轻微后仰状态。
