    • A tire burst predicting device which can predict occurrence of bursting of a tire and gives an alarm properly is provided. A break point frequency is estimated on the basis of time series data of wheel speed detected at a wheel speed sensor from frequency response of a first order model to which a transmission characteristic from a road surface disturbance to a wheel speed is approximated. A braking force gradient corresponding to the estimated break point frequency is estimated, on the basis of a map, which is prestored, representing a relationship between break point frequencies and braking force gradients. Extra high frequency components are eliminated from the estimated braking force gradient by a low pass filter to reduce estimation dispersion. Differentiators detect changing speed of the braking force gradient. An alarm is given when there is a possibility of bursting of tire when the detected changing speed reaches or exceeds a predetermined threshold value.
    • 提供一种可以预测轮胎爆裂发生并发生报警的轮胎爆破预测装置。 基于从车轮速度传感器检测到的车轮速度的时间序列数据,根据从路面干扰到车轮速度的传输特性近似的第一阶模型的频率响应来估计断点频率。 基于预先存储的表示断点频率和制动力梯度之间的关系的映射来估计对应于估计的断点频率的制动力梯度。 通过低通滤波器从估计的制动力梯度中消除超高频分量,以减少估计分散。 微分器检测制动力梯度的变化速度。 当检测到的变化速度达到或超过预定阈值时,当存在轮胎爆裂的可能性时,发出报警。

    • A wheel velocity signal for each wheel detected by a wheel velocity sensor is input to a bandpass filter. Signals from frequency bands unrelated to the unsprung resonance are then removed from the wheel velocity signal and only signals from frequency bands related to the unsprung resonance are output. A road surface &mgr; gradient estimation device uses an online identification method to identify an damping ratio of a second order resonance model similar to a suspension—tire resonance model from the signal output from the bandpass filter. The road surface &mgr; gradient is then estimated from the identified damping ratio. The damping ratio of the second order resonance model corresponds to the road surface &mgr; gradient in the following manner: when the damping ratio is identified as being small, the road surface &mgr; gradient is estimated as being large; and when the road surface &mgr; gradient is identified as being large, the damping ratio is estimated as being small.
    • 由车轮速度传感器检测到的每个车轮的车轮速度信号被输入到带通滤波器。 然后从不同于簧下共振的频带发出的信号从车轮速度信号中除去,并且仅输出与非簧下共振相关的频带的信号。 路面mu梯度估计装置使用在线识别方法从与带通滤波器输出的信号相似的悬挂轮胎共振模型中识别类似于二次谐振模型的阻尼比。 然后根据所识别的阻尼比估计路面μm梯度。 二次谐振模型的阻尼比以下列方式对应于路面μ0的梯度:当阻尼比被识别为小时,路面μ0的梯度被估计为较大; 并且当路面μm梯度被识别为大时,阻尼比被估计为小。

    • A deviation angle, between a progression direction of a vehicle and a direction of a target destination point after a predetermined forward gaze duration on a target course the vehicle is travelling on, is detected by target destination point deviation angle detection unit. A yaw angular speed proportional to the deviation angle detected by the target destination point deviation angle detection unit is predicted by yaw angular speed prediction unit, as a yaw angular speed realized by steering wheel operation by a driver after a predetermined lag time for matching a timing of change in the vehicle movement with a timing of change in curvature of the target course. By so doing, the yaw angular speed due to steering wheel operation by a driver can be predicted with good precision.
