The invention relates to a semi-active suspension and a semi-active suspension control method and device. A first supporting column assembly is composed of a damping continuously-adjustable electric control shock absorber, and a second supporting column assembly is composed of a frequency damping adjustable shock absorber. The first strut assembly is integrally configured with a signal acquisition system; the method comprises the following steps: acquiring driving state information of a vehicle through a signal acquisition system, and sending the driving state information to a control system; the control system is configured to determine a target damping value for the damping continuous adjustable electric control shock absorber based on the driving state information, and the target damping value is adopted to control the damping continuous adjustable electric control shock absorber to provide shock absorption of partial areas for the vehicle; the frequency damping adjustable shock absorber is used for responding to road excitation to provide shock absorption for partial areas of a vehicle when the vehicle is subjected to road excitation, so that the production cost of the vehicle is reduced on the basis of ensuring the shock absorption efficiency of the vehicle.

    本发明涉及一种半主动悬架、半主动悬架控制方法和装置,使第一支柱总成由阻尼连续可调电控减振器构成,且第二支柱总成由频率阻尼可调减振器构成;使第一支柱总成集成配置有信号采集系统;通过信号采集系统获取针对车辆的行驶状态信息,并将行驶状态信息发送至控制系统;通过控制系统被配置基于行驶状态信息确定针对阻尼连续可调电控减振器的目标阻尼值,并采用目标阻尼值控制阻尼连续可调电控减振器为车辆提供部分区域的减震;使频率阻尼可调减振器用于在车辆受到路面激励时,响应路面激励为车辆提供部分区域的减震,从而实现了在保证了针对车辆的减震效率的基础上,降低了车辆的生产成本。
