Abstract: A vehicle includes an engine, an accelerator pedal, and a controller. The controller is programmed to command torque to the engine based on a set speed of adaptive cruise control and is programmed to, in response to the adaptive cruise control being active, a measured lateral acceleration of the vehicle exceeding a user-defined lateral acceleration threshold during a road curve, and the accelerator pedal being released, reduce a speed of the vehicle below the set speed until the measured lateral acceleration is less than the lateral acceleration threshold.

Abstract: A vehicle includes a transmission, friction brakes, and a controller. The transmission has a clutch that is configured to transfer torque from an input of the transmission to a drive wheel. The controller is programmed to, in response to application of the friction brakes resulting in a stationary position of the vehicle, disengage the clutch to establish a neutral condition of the transmission. The controller is also programmed to, in response to a command to launch the vehicle while the transmission is in the neutral condition, engage the clutch. The controller is further programmed to, in response to an estimated wheel torque exceeding a rollback threshold during the clutch engagement, release the friction brakes. The wheel torque is based on an estimated clutch torque which is based on a clutch pressure and a transmission input torque.

Abstract: Systems and methods for reducing perception of transitions from shifting a transmission from neutral to drive are described. In one example, the transmission is shifted from neutral to drive in response to brake pedal motion before the brake pedal is fully released so that timing of pressurizing clutches and engaging a forward gear is advanced to occur while the brake pedal is still applied.

Abstract: A vehicle includes an engine and driven wheels each having an associated friction brake. A brake pedal is operable to engage the friction brakes. The vehicle includes a transmission having an input shaft driveably connected to the engine, an output element driveably connected to the driven wheels, and a gear mechanism adapted to establish at least one torque flow path between the input shaft and the output element. The transmission further includes a shift element that interrupts the torque flow path when disengaged. A gear selector is disposed in the passenger cabin and includes at least one forward-drive position, a reverse position, and a neutral position. At least one vehicle controller is configured to, in response to the gear selector being in the forward-drive position, a speed of the vehicle being zero, the vehicle being within a first predefined distance of a stoplight, and the brake pedal being depressed, disengage the shift element to put the transmission in neutral idle.

Abstract: A transmission controller implements a neutral idle feature to reduce fuel consumption. A brake controller implements a Hill Start Assist feature to prevent roll-back when a vehicle is launching on an uphill grade. The transmission controller and the brake controller communicate to implement these features in a synergistic manner. Within certain road grade ranges, the transmission requests Hill Start Assist before activating neutral idle and does not activate neutral idle until it receives confirmation that Hill Start Assist is active. The transmission controller provides a powertrain torque estimate to the brake controller which the brake controller uses to determine when to release the brakes during an assisted start.

Abstract: A method of controlling a Continuously Variable Transmission (CVT) simulates a step-ratio transmission upshift. To simulate a step-ratio torque phase, the input torque is gradually reduced before beginning to change the variator ratio. Then, as the variator ratio is changed, the input torque is gradually increased to compensate for the decreasing torque ratio, simulating the relatively constant output torque of an inertia phase of a step-ratio upshift.

Abstract: A vehicle includes an electric machine including a rotor. The vehicle further includes a traction battery configured to supply electric power to the electric machine. The vehicle further includes a wheel mechanically coupled to the electric machine. The vehicle further includes one or more controllers programmed to, responsive to detecting a battery temperature below a threshold and the vehicle being parked, rotate the rotor to a preset position such that the wheel rotates.

Abstract: An electric drive system is actively controlled while an electrified vehicle is being towed. The inverter switches are manipulated to preclude exceeding a maximum voltage of a DC bus and also to preclude exceeding a maximum phase current magnitude. During a transition from an inverter off state to a short-circuit state, field-oriented control is utilized.

Abstract: A hybrid vehicle includes an engine, an electric machine, a disconnect clutch configured to selectively couple the engine to the electric machine, and a controller. The controller is programmed to, in response to a request to start the engine with the electric machine, command a target pressure to the disconnect clutch that depends on a seal friction derived from a measured line pressure of the disconnect clutch and a rate change of the measured line pressure.
