METHOD FOR ESTIMATING AND ADJUSTING THE SPEED AND ACCELERATION OF A VEHICLE

The invention relates to a method for estimating the speed of a motor vehicle, in which: A. a first speed threshold SV1 is defined, corresponding to a minimum speed value provided by an angular wheel speed sensor of the vehicle B. a second speed threshold SV2 is defined, greater than SV1; C. low-spe...

Beschreibung
Zusammenfassung:	The invention relates to a method for estimating the speed of a motor vehicle, in which: A. a first speed threshold SV1 is defined, corresponding to a minimum speed value provided by an angular wheel speed sensor of the vehicle B. a second speed threshold SV2 is defined, greater than SV1; C. low-speed values are estimated when the vehicle travels below SV1 using an adaptive filter estimation method; D. high-speed values are measured when the vehicle travels above SV2 using speed values of the vehicle provided by the angular wheel speed sensor; E. in the intermediate region between SV1 and SV2, a mixing is performed of the high speed with the low speed. 本发明涉及一种用于估计机动车辆的速度的方法，其中：A.定义与由车辆车轮角速度传感器提供的最小速度值相对应的第一速度阈值SV1；B.定义了大于SV1的第二速度阈值SV2；C.当该车辆在SV1以下行驶时，通过使用自适应滤波类型的估计方法来估计低速度值；D.当该车辆在SV2以上行驶时，通过使用由该车轮角速度传感器提供的车辆速度值来测量高速度值；E.在SV1与SV2之间的中间区域中，存在高速度与低速度的混合。
