The invention provides a slip state detection device and a suspension control device. The suspension control device unit has a slip state detection device for detecting the slip state of the wheel. The slip state detection device has a second slip rate calculation unit, a slip rate allocation calculation unit, and a third slip rate calculation unit. The second slip rate calculation unit obtains a slip rate (second slip rate) taking into account tire characteristics on the basis of the front-rear acceleration (front-rear acceleration) of the vehicle detected by the front-rear acceleration sensor and the tire characteristics (slip rate coefficient). The slip rate allocation calculation unit calculates the ratio of the slip rate of each vehicle. A third slip rate calculation unit corrects a slip rate (second slip rate) in consideration of tire characteristics at a ratio of the slip rate of each wheel obtained from the rotational speed signal of each wheel, and obtains a corrected slip rate (third slip rate) of each wheel.
一种滑移状态检测装置及悬架控制装置。悬架控制装置单元具有用于检测车轮的滑移状态的滑移状态检测装置。滑移状态检测装置具有第二滑移率计算部、滑移率分配计算部、第三滑移率计算部。第二滑移率计算部根据由前后加速度传感器检测出的车辆的前后加速度(前后加速度)和轮胎特性(滑移率系数)求出考虑轮胎特性的滑移率(第二滑移率)。滑移率分配计算部计算各车辆的滑移率的比例。第三滑移率计算部以根据各车轮的转速信号求出的各车轮的滑移率的比例修正考虑轮胎特性的滑移率(第二滑移率),求出各车轮的修正滑移率(第三滑移率)。
