TL;DR: In this article, the braking force provided by the engine brake or retarder in dependence on the difference in the rotation between the braked wheels and the non-braked wheels was determined.
Abstract: the control system determines the braking force provided by the engine brake or retarder in dependence on the difference in the rotation between the braked wheels and the non-braked wheels. The braking force is reduced when the difference in the wheel rotation rates exceeds a value which is below the threshold value used for activating anti-locking braking regulation. Pref. the reduction in the braking force is defined by the differential of the difference in the wheel rotation rates, with stepped reduction of the braking in successive cycles.

TL;DR: In this article, a braking system for two-wheelers is provided with a normal-duty actuation member which acts on both a front braking assembly and a rear braking assembly, and with an emergency actuation mechanism which acts only on one of the two braking assemblies.
Abstract: A braking system for two-wheelers is provided with a normal-duty actuation member which acts on both a front braking assembly and a rear braking assembly, and with an emergency actuation member which acts on one only of said braking assemblies; means are provided for balancing the actuation force applied by the normal-duty actuation member and the actuation force applied by the emergency actuation member on the common braking assembly, which enable the greater of the two braking actions to be applied as the braking action, for the purpose of preventing the jamming, and hence the skidding of the vehicle wheel on which such common braking assembly acts.

TL;DR: In this article, the principles involved and the many factors that influence braking temperatures are considered, and analytical and numerical methods are described that enable temperature distributions in the brake to be determined for both transient and continued braking.
Abstract: Friction brakes must be designed and dimensioned so that they can dissipate the heat generated during braking and yet avoid excessive temperatures and stresses at the friction interface. In this paper the principles involved and the many factors that influence braking temperatures are considered. Analytical and numerical methods are described that enable temperature distributions in the brake to be determined for both transient and continued braking. The solutions obtained by considering a one-dimensional heat problem have been applied to single stops made from high vehicle speeds and to continued braking down a steep Alpine descent as severe applications of importance to railway brake engineers.

TL;DR: In this article, a new regenerative braking strategy tailored specially for parallel hydraulic hybrid vehicles (PHHV) was proposed to improve the fuel economy, based on the analysis of the characteristics of braking in the city drive cycle and high power density of HV.
Abstract: Parallel hydraulic hybrid vehicles (PHHV) have the potential of improving fuel economy by operating the engine in the optimum efficiency range and making use of regenerative braking during deceleration. Based on the analysis of the characteristics of braking in the city drive cycle and high power density of hydraulic hybrid vehicles, a new regenerative braking strategy tailored specially for PHHV was proposed to improve the fuel economy. The simulation results shown that hydraulic regenerative braking strategy reasonably distributed the hydraulic regenerative braking torque and traditional friction braking torque, effectively regenerated braking energy of the vehicle under the premise of safety brake and improved the braking performance.

TL;DR: In this article, a mathematical model-based study of the limit braking of a high-performance motorcycle and rider is described, where both front and rear brakes are operable independently, and parameters of the braking control schemes are derived with the help of an optimization process, minimising the final speed in braking from high speed over a fixed time interval.
Abstract: A mathematical-model-based study of the limit braking of a high-performance motorcycle and rider is described. Front and rear brakes are operable independently. A dry road and high friction are presumed, such that full braking of the front wheel would lead to an overturn or ‘stoppie’ in colloquial parlance. Effective braking needs to maintain some loading on the rear wheel. A planar but otherwise detailed system model is set up and braking strategies for front and rear are devised. Parameters of the braking control schemes are derived with the help of an optimisation process, minimising the final speed in braking from high speed over a fixed time interval. Simulation results are examined critically and the strategy is developed until efficient use of the friction available is made. The nature of optimal braking events is demonstrated. The influences of slipper-clutch torque setting and the rear-tyre target load chosen are shown.
