Estimation of the Maximum Tire-Road Friction Coefficient
We develop and test a ‘‘slip-based’’ method to estimate the maximum available tire-road friction during braking. The method is based on the hypothesis that the low-slip, low-m parts of the slip curve used during normal driving can indicate the maximum tire-road friction coefficient, mmax . We find support for this hypothesis in the literature and through experiments. The friction estimation alg...
متن کاملRoad Friction Coefficient Estimation For Vehicle Path Prediction
One of the most noticeable trends of the automotive industry in the 1990's is the emerging of active safety technologies. Instead of passive protection and crash worthiness, emphasis has been shifted toward accident prevention and damage reduction using active safety techniques. To develop effective active safety devices, it is necessary to estimate vehicle motions accurately, and reliable road...
متن کاملTire-road friction estimation and traction control strategy for motorized electric vehicle
In this paper, an optimal longitudinal slip ratio system for real-time identification of electric vehicle (EV) with motored wheels is proposed based on the adhesion between tire and road surface. First and foremost, the optimal longitudinal slip rate torque control can be identified in real time by calculating the derivative and slip rate of the adhesion coefficient. Secondly, the vehicle speed...
متن کاملSlip-based Estimation of Tire|road Friction
An approach to estimate the tire{road friction during normal drive using only the wheel slip, that is, the relative diierence in wheel velocities, is presented. The driver can be informed about the maximal friction force and be alarmed for sudden changes. Friction related parameters are estimated using only signals from standard sensors in a modern car, and the physical relation between these p...
متن کاملEstimation of Tire-Road Friction by Tire Rotational Vibration Model
Tire-road friction is the most important piece of information used by active safety systems. However, most conventional friction estimation/ detection methods are accurate only within the non-linear region. In addition, such methods require numerous sensors, such as yaw rate sensors, acceleration sensors, and steering angle sensors. In this paper, a friction estimation method using a tire vibra...
