In steer-by-wire vehicle, it is possible to design the characteristics of vehicle dynamics like the yaw response. However, the gain and phase of the frequency response of linear systems are coupled which limits the tunability. Therefore, when one characteristic is changed, the other is changed ...

There are a number of procedures of analysing the zig-zag test to obtain the steering quality parameters of a relevant ship, ranging from the simple method with the first-order (K and T) equation to the phase-plane analysis taking the hi... Kensaku,Nomoto,Kuniji,... - 《Journal of the...
In (A.5), the first fractional equation is a kinematic formula for the actual yaw rate ract. Replacing that part with ract and rearranging results in (A.6) VRR and VRL are substituted for from (A.2) and (A.3). Rearranging results in (A.7) which can be reexpressed as the recu...
Desired yaw rate provides the expected vehicle path information; however, due to external disturbance such as cross wind, asymmetric friction coefficients on front, and rear tires, there exists an error in the yaw rate and it can be calculated using the following equation: (8) In order to ...
wheels of the vehicle, said tongue length estimation controller calculating the estimate of the tongue length of the trailer based on all of the front wheel angle signal, the rear wheel angle signal, the vehicle yaw rate signal, the vehicle speed signal and the actual trailer yaw rate signal....
logging ■ Motion-activated functions ■ Intelligent power-saving for handheld devices ■ Free-fall detection LGA-28L (4.4x7.5x1.1mm) Description The LSM320HAY30 is a low-power system-in- package featuring a 3D digital linear acceleration sensor and a 2D analog angular rate pitch and yaw ...
From input quantities, the controller determines a desired steering gear ratio by using equations of motion so that a desired steady state side slip angle (尾), and a desired steady state yaw rate gain (G) can be obtained, and further determines a desired rear wheel steer angle by using ...
