The present invention provides a tire state estimating device, a control method of a tire state estimating device, and a non-transitory storage medium. The tire state estimating device (1; 1A) includes an electronic control unit. The electronic control unit is configured to acquire generated force of a tire. The electronic control unit is configured to acquire a friction coefficient between the tire and a road surface. The electronic control unit is configured to derive a grip margin of the tire. The electronic control unit is configured to estimate a contact length of the tire in an uncontrolled drive state. The electronic control unit is configured to estimate a cornering power of the tire, based on the contact length of the tire that is estimated and the generated force of the tire that is acquired.
提供一种轮胎状态估算装置、轮胎状态估算装置的控制方法和非暂态存储介质。该轮胎状态估算装置(1;1A)包括电子控制单元。该电子控制单元被构造成获取轮胎的生成力。电子控制单元被构造成获取轮胎和路面之间的摩擦系数。电子控制单元被构造成导出轮胎的抓地力裕度。电子控制单元被构造成在非受控驱动状态下估算轮胎的接地长度。电子控制单元被构造成:基于所估算出的轮胎的接地长度和所获取到的轮胎的生成力来估算轮胎的转弯能力。
