Abstract: A system includes a reference speed module and a motor control module. The reference speed module is configured to determine a reference speed range based on a speed of a left wheel of a pair of front or rear wheels of a vehicle and a speed of a right wheel of the pair of front or rear wheels. The right wheel is disconnected from the left wheel. The motor control module is configured to control at least one of a first electric motor and a second electric motor based on the reference speed range. The first electric motor is connected to the left wheel. The second electric motor is connected to the right wheel.

Abstract: A longitudinal vehicle speed sensor for a vehicle includes a first sensor configured to generate a first measured speed based on one of a wheel speed of the vehicle receiving output torque from a drive unit and an output of a global positioning system (GPS). A second sensor is configured to generate a second measured speed. A speed weighting module is configured to apply a first weight to the first measured speed to generate a first weighted speed. A speed weighting module is configured to apply a second weight to the second measured speed to generate a second weighted speed. An output module is configured to generate a speed estimate based on the first weighted speed and the second weighted speed.

Abstract: A method of determining a commanded friction brake torque is disclosed. The method uses inputs, such as from a gearshift sensor, an accelerator pedal sensor, a brake pedal sensor, and engine torque output sensor, a transmission speed input sensor and a transmission speed output sensor, to determine how much engine braking or regenerative braking is occurring. The method then uses this information combined with the braking command information from the brake pedal sensor to determine the amount of friction braking to apply to the friction brakes.

Abstract: A method of operating a powertrain system during coasting operation, wherein the powertrain system includes a driveline component (e.g., a transmission, drive shaft, differential, axle or wheel) having an output torque profile. The method includes: (i) determining a desired output torque transition profile for the driveline component between a first transition point before an end of a first state, and a second transition point after a beginning of a second state; and (ii) in response to a braking torque request, generating a friction braking torque command to operate a friction braking system, and adjusting the friction braking torque command during a transitional state between the first and second transition points by an amount corresponding to a difference between a magnitude of the output torque profile and a magnitude of the desired output torque transition profile.
