The invention relates to a vehicle behavior estimation system and a vehicle behavior estimation method. The vehicle behavior estimation system includes: a yaw rate sensor that detects a yaw rate of a diagnostic target vehicle; a vehicle speed sensor that detects a vehicle speed of the diagnosis target vehicle; and a processor. The processor acquires a first curvature that is a curvature of a traveling trajectory of the diagnosis target vehicle based on the yaw rate and the vehicle speed, and performs a driving diagnosis related to steering of the diagnosis target vehicle based on a criterion and a curvature-related value. The criterion defines a relationship between a steering angle related value, which is a value based on a steering angle of a steering wheel of a reference vehicle, and a behavior of the reference vehicle caused by steering, the reference vehicle being a vehicle different from the diagnostic target vehicle. The curvature-related value is a value based on the first curvature.

    本公开涉及车辆行为估计系统及车辆行为估计方法。所述车辆行为估计系统包括:横摆率传感器,其检测诊断目标车辆的横摆率;车速传感器,其检测所述诊断目标车辆的车速;以及处理器。所述处理器基于所述横摆率和所述车速获取作为所述诊断目标车辆的行驶轨迹的曲率的第一曲率,并且基于标准和曲率相关值执行与所述诊断目标车辆的转向相关的驾驶诊断。所述标准定义了转向角相关值和由转向引起的基准车辆的行为之间的关系,所述转向角相关值是基于所述基准车辆的转向盘的转向角的值,所述基准车辆是与所述诊断目标车辆不同的车辆。所述曲率相关值是基于所述第一曲率的值。
