Design of a hydraulic anti-lock braking modulator and an intelligent brake pressure controller for a light motorcycle 总被引:1,自引:0,他引:1

The object of this paper is to design a new hydraulic modulator and an intelligent sliding mode pulse width modulation (PWM) brake pressure controller for an anti-lock braking system, for application to light motorcycles. The paper presents a design principle and a mathematical analysis of the hydraulic anti-lock braking modulator. The intelligent sliding mode PWM brake pressure controller based on vehicle acceleration is designed and tested. A three-phase pavement experiment and a rear brake influence test are undertaken to verify the performance of the controller and the modulator. A light motorcycle is built for the real vehicle anti-lock braking experiments. The experimental results show that both the intelligent controller and the hydraulic modulator designed in the study perform well in the anti-lock braking operation. 相似文献

According to European regulations, if the amount of regenerative braking is determined by the travel of the brake pedal, more stringent standards must be applied, otherwise it may adversely affect the existing vehicle safety system. The use of engine or vehicle speed to derive regenerative braking is one way to avoid strict design standards, but this introduces discontinuity in powertrain torque when the driver releases the acceleration pedal or applies the brake pedal. This is shown to cause oscillations in the pedal input and powertrain torque when a conventional driver model is adopted. Look-ahead information, together with other predicted vehicle states, are adopted to control the vehicle speed, in particular, during deceleration, and to improve the driver model so that oscillations can be avoided. The improved driver model makes analysis and validation of the control strategy for an integrated starter generator (ISG) hybrid powertrain possible. 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
