In this paper, we propose a new control strategy for an antilock braking system (ABS) to maintain the braking force at maximum. The popularization of the ABS that prevents the wheels from locking has resulted in an improvement of the vehicle stability and shortening of the braking distance. Further improvement is anticipated if the maximization of the braking force is realized. We found an interesting phenomenon in which the characteristics of the resonance system composed of the vehicle body and the wheel and road surface reflects the slip condition of the road surface. Using this phenomenon, we realized a control method for maintaining the maximum value of the braking force. 相似文献

Braking Force Distribution Control for Improved Vehicle Dynamics and Brake Performance 总被引:1,自引:0,他引:1

This paper describes the feasibility of improving the braking performance of a commercial vehicle by using an electronic braking system. An electronic braking system enables the braking force at each wheel to be independently controlled. Braking force distribution control makes the braking force at each wheel proportional to each wheel's load. Results of computer simulation and vehicle test showed that the proposed control laws can eliminate the effects of a laden condition on the braking distance and can increase the degree of deceleration at which wheel lock occurs, resulting in improved vehicle attitude stability during a critical maneuver. 相似文献

A study on effective use of rear braking force to improve a brake performance and vehicle dynamics are carried out. On a ordinary condition, the rear braking force could be more increased to a conventional braking force distribution. Based on this thought, the brake performances are estimated. The results show the effects not only improve the brake performance but also reduce a pitching at braking and moderate a vehicle OS behavior in a turn during braking. These are verified by experimental test vehicle equipped with a rear braking force control system. 相似文献

防抱制动系统控制算法的仿真研究 总被引:8,自引:0,他引:8
本文用要平面法分析了目前汽车上广泛使用的P1R3逻辑控制算法在不同条件下的收敛性,因这种算法只能使车轮的滑移率在μ-S曲线的峰值点变化,故采用逻辑控制的ABS系统不能充分发挥它的最佳效能,本文进一步通过仿真研究了基于滑移率S的控制算法,并根据逻辑控制和滑移率控制的缺陷,提出了基于路面附着系数μ的控制算法,在理想状态下的证实了所提算法的有效性。 相似文献
