A method is provided for decelerating a vehicle. The vehicle has an electro-pneumatic brake system, at least one front axle, at least one rear axle, and a brake value transmitter. The vehicle further includes at least one axle modulator for the front axle of the vehicle, for performing control of at least one front axle brake pressure at the at least one front axle, and/or at least one axle modulator for the rear axle of the vehicle, for performing control of a rear axle brake pressure at the at least one rear axle of the vehicle. The method includes generating a redundancy signal at a first axle, the front axle or rear axle, or at a trailer control valve, and performing open-loop and/or closed-loop control of an auxiliary brake pressure at another axle, the front axle or the rear axle, via the redundancy signal.

A controller for a vehicle is provided. One of a prime mover that drives a front wheel and a prime mover that drives a rear wheel is referred to as a first prime mover, and the other one is referred to as a second prime mover. The controller generates, when a required torque required for a drive wheel of the vehicle is a braking torque, the braking torque from the first prime mover. The controller limits, when the required torque changes from the braking torque to a driving torque, an increase in the driving torque generated from the first prime mover during a set period. The controller generates, from the second prime mover that does not generate the braking torque, the driving torque required during execution of the torque limit process.

A vehicle pedal emulator assembly comprising a housing and a sleeve both defining an interior cavity. The sleeve is adapted for sliding movement in the interior cavity of the housing. Respective first, second, third, and fourth springs located in opposed ends of the interior cavity of the housing are compressible in parallel in response to the sliding movement of the sleeve in the interior cavity of the housing. The first and second springs surround the shaft and extend between one end of the housing and one end of the shaft. The third and fourth springs extend between one end of the sleeve and the other end of the sleeve. The combination of an inductive sensor and a Hall Effect sensor are adapted for measurement of the position of the sleeve relative to the housing.

A control system includes one or more processing circuits comprising one or more memory devices coupled to one or more processors. The one or more memory devices are configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to acquire speed data regarding current speeds of tractive elements of the vehicle from tractive element speed sensors of the vehicle, determine speed references for the tractive elements to perform autonomous driving operations where the speed references indicate speeds at which each of the tractive elements should rotate to accommodate the autonomous driving operations, and control at least one of a driveline or a brake system of the vehicle to selectively alter the current speeds of the tractive elements of the vehicle based on the current speeds and the speed references to accommodate the autonomous driving operations.
