一种基于路谱信息的空气悬挂系统及控制方法
摘要：
本发明涉及一种基于路谱信息的空气悬挂系统，包括ECU单元、储气罐、与ECU单元相连接的空气压缩机、分配阀、左前高度传感器、右前高度传感器、左后高度传感器、右后高度传感器、左前可变阻尼减震器、右前可变阻尼减震器、左后可变阻尼减震器、右后可变阻尼减震器、至少一个加速度传感器、电子陀螺仪、前路谱传感器、后路谱传感器，储气罐、分配阀均与空气压缩机相连接，储气罐与分配阀相连接，分配阀连接有左前空气弹簧、右前空气弹簧、左后空气弹簧、右后空气弹簧。本发明还涉及一种基于路谱信息的空气悬挂系统的控制方法。本发明能够有效降低对减震器和空气弹簧执行器件响应速度的要求，减小执行器的影响，提高空气悬挂系统的舒适性和安全性。
摘要（英）：

The invention relates to an air suspension system based on road spectrum information. The air suspension system based on the road spectrum information comprises an ECU unit, an air storage tank, an air compressor connected with the ECU unit, a distribution valve, a left front height sensor, a right front height sensor, a left rear height sensor, a right rear height sensor, a left front variable damping shock absorber, a right front variable damping shock absorber, a left rear variable damping shock absorber, a right rear variable damping shock absorber, at least one acceleration sensor, an electronic gyroscope and a front road spectrum sensor and a rear path spectrum sensor; the air storage tank and the distribution valve are all connected with the air compressor; the air storage tank is connected with the distribution valve; and the distribution valve is connected with a left front air spring, a right front air spring, a left rear air spring and a right rear air spring. The inventionalso relates to the control method of the air suspension system based on the road spectrum information. According to the air suspension system based on the road spectrum information and the control method, the requirement on the response speed of a shock absorber and an air spring actuating device can be effectively reduced, the influence of an actuator is reduced, and the comfort and safety of the air suspension system are improved.
