TL;DR: In this paper, the authors present a method and a system for controlling a stand-by braking torque applied to an automotive vehicle under a condition of approaching or following an obstacle preceding the vehicle, the automotive vehicle having a powering system for applying a driving torque to the vehicle in response to an operator power demand.
Abstract: The present invention pertains a method and a system for controlling a stand-by braking torque applied to an automotive vehicle under a condition of approaching or following an obstacle preceding the vehicle, the automotive vehicle having a powering system for applying a driving torque to the vehicle in response to an operator power demand. A brake controller executes a series of instructions for determining a variable indicative of dynamic situation of the vehicle, for sampling the determined values of the dynamic situation indicative variable immediately before an operator braking action to reduce the speed of the vehicle is imminent, for using the sampled values of the dynamic situation indicative variable as a basis to establish a parameter, and for using the established parameter as a basis to determine a target value of stand-by braking torque.

TL;DR: In this article, an electro-hydraulic brake system for an extended range electric vehicle equipped with axle motors was modeled and an optimal braking strategy was proposed to maximize energy recovery.
Abstract: This work focuses on modelling of an electro-hydraulic brake system for an extended range electric vehicle equipped with axle motors, and proposing an optimal braking strategy which utilises a two-layer split of braking action such that the desired braking force is first distributed to the front and rear axles in order to track the ideal brake force distribution factor and, then, to the electro-hydraulic friction brakes and electric motors in order to maximise energy recuperation. With simulation results, it is shown that the proposed regenerative braking strategy achieves the dual objective of ensuring a good dynamic performance and optimal energy recovery.

25 Oct 1977TL;DR: In this paper, a drive train includes a hydrostatic transmission unit and a multiple speed range transmission unit arranged in series between a prime mover and a primary output shaft, variable displacement and torque transmitting capacity of the transmission unit being adjusted by hydraulic controls including a speed control valve for developing a differential pressure signal proportional to a desired rate of operation.
Abstract: A drive train includes a hydrostatic transmission unit and a multiple speed range transmission unit arranged in series between a prime mover and a primary output shaft, variable displacement and torque transmitting capacity of the hydrostatic transmission unit being adjusted by hydraulic controls including a speed control valve for developing a differential pressure signal proportional to a desired rate of operation, a modulating valve for regulating the differential pressure signal corresponding to accelerating and decelerating operation of the transmission, a directional control valve for determining the direction of operation of the hydrostatic transmission unit, and a range selector valve for shifting the operating speed range of the multiple speed range transmission as the hydrostatic transmission approaches a limit of displacement, the displacement of the hydrostatic transmission being automatically reset in response to shifting of the multiple speed range transmission. Operating speed limits are automatically established for the drive train by an override speed control valve which manually adjusts the differential pressure signal for reduced torque transmission through the drive train when the prime mover is operating below a minimum speed. A speed limiting control valve responds to operation of the prime mover above a maximum selected speed for automatically applying a brake within the drive train in order to supplement dynamic braking capacity of the transmission unit, the speed limiting control valve including means producing a feedback signal for resisting manual operation of the override speed control valve in proportion to engagement of the brake within the drive train.

TL;DR: In this article, a method for controlling the braking force of motorcycles, which includes storing the vehicle deceleration value which was measured when a lift-off signal occurred as an optimal limit value, was proposed.
Abstract: A method for controlling the braking force of motorcycles, which includes storing the vehicle deceleration value which was measured when a lift-off signal occurred as an optimal deceleration limit value and reducing the braking force applied to the front brakes if the motorcycle deceleration approaches or exceeds this limit. A lift-off signal is generated if after a predetermined time from the initiation of a braking cycle, it is determined that the rear wheel has lost adherence to the grounds.
