TL;DR: In this article, a control unit connected for signal communication to the regenerative braking unit, and configured to perform the following: measuring a wheel speed deviation defined as a difference between a front wheel set of the vehicle and a speed of a rear wheel set.
Abstract: A regenerative braking control apparatus for a wheeled vehicle, includes: a regenerative braking unit arranged to produce a regenerative braking effort for the vehicle; and a control unit connected for signal communication to the regenerative braking unit, and configured to perform the following: measuring a wheel speed deviation defined as a difference between a speed of a front wheel set of the vehicle and a speed of a rear wheel set of the vehicle; and controlling the regenerative braking effort in accordance with the wheel speed deviation during cornering. The control unit is configured to control the regenerative braking effort to decrease with an increase in the wheel speed deviation during cornering braking, and configured to perform braking for the vehicle in accordance with an operation of slowdown request, prioritizing a regenerative braking effort for one of the front wheel set and the rear wheel set of the vehicle.

TL;DR: In this article, a brake control system for a railway vehicle having an a. c. inverter drive for an induction type motor capable of being operated in a regenerative mode to effect vehicle retardation by either supplying current flow to the system supply source (regenerative braking) for use by other vehicles operating in a power mode or by dissipating the current flow in the form of heat at resistive grids (dynamic braking).
Abstract: A brake control system for a railway vehicle having an a. c. inverter drive for an induction type motor capable of being operated in a regenerative mode to effect vehicle retardation by either supplying current flow to the system supply source (regenerative braking) for use by other vehicles operating in a power mode or by dissipating the current flow in the form of heat at resistive grids (dynamic braking). The system is normally conditioned so that regenerative braking provides the primary source of vehicle retardation with the torque effort produced being compared with the brake or torque command to effect a friction brake application in accordance with the difference therebetween. The friction brake thus supplements the regenerative brake up to a predetermined point at which it is desired to establish dynamic braking. Once the dynamic brake applies, the combined regenerative and dynamic brake effectiveness results in the torque effort being increased so that the difference between torque effort and torque command is reduced and accordingly the friction brake is released proportionately, thereby providing for combining the friction, dynamic and regenerative brakes, or any combination thereof, in an attempt to provide and maintain a constant rate of deceleration irrespective of variable conditions affecting the degree of regenerative and dynamic braking available.

TL;DR: In this paper, a braking and driving system for electrically operated vehicles including an electric motor for driving the vehicle which may be operated as a generator to provide additional braking and recovery of braking energy by charging the battery.
Abstract: A braking and driving system for electrically operated vehicles including an electric motor for driving the vehicle which may be operated as a generator to provide additional braking and recovery of braking energy by charging the battery. Hydraulic braking on the drive axle is delayed until the maximum level of electromotive braking is reached. This allows the design distribution of braking between the front and rear axles to be maintained while insuring a maximum recovery of braking energy through charging of the battery.
