Abstract: A system and method for accessing coherent data on a controller. The system and method include a first buffer and a second buffer that each may be read from or written to and an indicator that indicates which of the first or the second buffer is read from while the other of the first or second buffers is written to. The system and method also include a read synchronization protocol that allows the coherent data to be read from the buffer that the indicator indicates is the read buffer and a write synchronization protocol that allows the coherent data to be written to the buffer that the indicator indicates is the write buffer.

Abstract: A system according to the principles of the present disclosure includes an exhaust braking enabling module, a driver torque module, and an engine actuator control module. The exhaust braking enabling module selectively enables exhaust braking based on driver input and independent of an accelerator pedal position. The driver torque module selectively determines a driver torque request based on a powertrain braking torque capacity when exhaust braking is enabled. The engine actuator control module controls fuel delivery to cylinders of an engine and a vane position of a turbocharger based on the driver torque request.
