High engine output torque may lead to high slip ratios of driven wheels and low utilization ofroad friction coefficients on a slippery road. 为了解决低附着路面上发动机输出力矩过大引起的驱动轮过度滑转及路面附着系数利用率低的问题,提出了牵引力控制系统中最优驱动力矩控制的概念并给出了其实现方法。
The method consists of three steps. First, we created labeled friction coefficient image datasets representing asphalt concrete surfaces under four moisture conditions. Second, we used a diffusion model to enhance the dataset, increasing sample diversity. Finally, we trained a TNT model on the ...
The formula can quickly calculate the friction coefficient between layers of asphalt pavement. Findings Based on quantitative analysis to the contacting state between layers of asphalt pavement in cold area, the relationships between generalized friction coefficient and resilient modulus of asphalt mixtures,...

Estimation of friction coefficient of asphalt concrete road surfaces using the fuzzy logic approachdoi:10.1139/l07-045Murat Ergun
the effects of aggregate texture, on a basis of texture scanning and pavement testing of the dynamic friction coefficient, traffic volume, and rock characteristics on pavement slide decay resistance were studied, and the accuracy of the developed prediction model of friction coefficient was thereafter ...
The main aim of this paper is to estimate the friction behavior of asphalt concrete road surfaces at any speed using the fuzzy logic approach. Friction is defined in the paper, and the effects of road surface characteristics, mainly macrotexture and microtexture properties, on the friction ...
