    Abstract: A vehicle brake system 10 is provided which compensates for brake pedal feel variation so as to provide for enhanced braking feel to the vehicle operator. The brake system 10 includes a brake command input 10, an accelerometer 22 for sensing longitudinal acceleration of the vehicle, and friction brakes 26 and regenerative brakes 29 for generating braking force to be applied to brakes on the vehicle. The vehicle brake system 10 further includes a controller 12 for detecting a brake torque variation as a function of the sensed acceleration and the brake demand signal. The controller 12 further adjusts a torque command signal to adjust the amount of braking torque generated by the brakes 26 so as to compensate for brake torque variation.

    Abstract: The invention relates to a control device for operating a road-coupled all-wheel drive vehicle having at least one electronic control unit, having at least a first drive motor as a primary motor assigned to a primary axle and having at least a second drive motor as a secondary motor assigned to a secondary axle. According to the invention, the control unit has a gradient-limiting module for performing a torque gradient limiting function in such a manner that, in the event of a change of the target all-wheel drive factor on the basis of a defined driver's request signal, first the new target all-wheel drive factor is predetermined in a sudden manner and second, in the course of the subsequent adjustment of the all-wheel drive factor, the gradient of the driver's request signal forms the gradient limitation for the maximum admissible adjustment of the torque of the primary motor and/or secondary motor.

    Abstract: Control systems and methods for an electrified powertrain of an electrified vehicle include performing, by a main control system, a sequence of first processes based on an initial input including a set of signals indicative of at least one of a driver torque request and expected vehicle behavior and other intermediary inputs to generate a sequence of first outputs and performing, by a secondary monitoring system distinct from the main control system, a sequence of second processes based on the initial input and other intermediary inputs to generate a sequence of second outputs. The secondary monitoring system then attempts to rationalize each first output relative to its respective second output. Based on the rationalization, one of these outputs is used as an intermediary output in the sequence until a rationalized final output is obtained and used to generate control commands for torque actuators of the electrified powertrain.
