An electric machine and internal combustion engine are coordinated to provide traction control for an automotive vehicle. A propulsive torque limit is set by a controller during a loss of traction. When the machine torque limit is greater than the propulsive torque limit, the engine is pulled down. When the machine torque is less than the propulsive torque limit, the engine is pulled up. The controller coordinates the pulled up engine with the machine such that the engine is subordinated to the machine.

Traction control for a hybrid electric powertrain

A stability control system for a vehicle that has an electric traction motor that provides torque to an axle through a differential. The traction motor responds to an instability event that is sensed by sensors on the vehicle by initially reducing the torque provided to the traction wheels to regain steering control. The traction motor then pulses increased torque in sequence with the application of braking force to provide enhanced direct yaw moment control.

Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission are described. In one example, regenerative torque and torque of an electronically controlled differential clutch are adjusted to increase utilization of a vehicle's kinetic energy.

Methods and system for hybrid vehicle regenerative braking

A method according to an exemplary aspect of the present disclosure includes, among other things, controlling a torque output of an electric machine of an electrified vehicle during a vehicle creep condition, the torque output calculated based at least on a road grade estimate and a vehicle mass estimate.

Creep compensation using road grade and mass estimation

A method and a system augment or improve a distance until charge (DUC) estimation for a vehicle such as a plug-in hybrid electric vehicle (PHEV) by using location information. Such location information may be provided by a global positioning system (GPS) or the like associated with the vehicle. The method and the system generally estimate the DUC value as a function of past driving pattern historical data that is relevant to a current driving situation. To this end, the method and the system ignore past driving pattern historical data that is not relevant to the current driving situation when estimating the DUC value.

A vehicle and vehicle system are provided with a controller that is configured to generate output indicative of a road gradient based on at least one of a first estimation, a second estimation and a third estimation. The road gradient is based on the first estimation when a vehicle speed is less than a speed threshold and an input indicative of a longitudinal acceleration is available. The road gradient is based on the second estimation when the vehicle speed is greater than the speed threshold and the longitudinal acceleration is available. The road gradient is based on the third estimation when the longitudinal acceleration is not available.

Road gradient estimation arbitration

A method for restarting an engine of a vehicle stopped on a grade, comprising the steps of engaging a gear of a transmission through which the engine and wheels of the vehicle are drivably connected mutually, using brake pressure to engage wheel brakes and produce a road gradient wheel torque that holds the vehicle stationary on the grade, initiating an engine restart, operating the engine to produce wheel torque equal to or greater than the road gradient wheel torque, and releasing the brake pressure.

Brake assisted vehicle engine restart on a road grade

A method includes controlling a torque output of an electric machine of an electrified vehicle based on estimated loads present during a transmission engagement of the electrified vehicle. Controlling the torque output may include merging a first feed-forward torque with a feedback torque if an input shaft of a transmission gearbox is spinning, or merging a second, different feed-forward torque with the feedback torque if the input shaft is not spinning.

Vehicle system and method for controlling torque delivery during transmission engagements with road grade and mass estimation

An exemplary electrified vehicle charging method includes waking a portion of an electrified vehicle, reading a state of charge for a battery of the electrified vehicle during the waking, charging the battery using an internal combustion engine in response to the reading if the electrified vehicle is in an open space, and disabling the charging if the electrified vehicle is in an enclosed space.

Electrified vehicle method and system for charging during a non-drive cycle

A vehicle may include a processor programmed to control operation of the vehicle. The processor may control operation of the vehicle according to an indication of a direction of travel. The indication of direction of travel may be based on signs of data representing jerk of the vehicle. The signs of data representing jerk may be derived from acceleration and speed sensor outputs. The indication may be such that the indication is reverse in response to the signs being opposite when the vehicle is in a forward drive gear.

Indication of vehicle direction of travel

A trailer backup assist system for a vehicle reversing a trailer is provided herein. The system includes a brake system and a steering system of the vehicle. A controller is configured to output a brake torque request to the brake system and a steering command to the steering system, wherein the brake torque request and the steering command are each based at least in part on a trailer mass.

Trailer backup aid speed limiting via braking

A plugin hybrid electric vehicle includes an internal combustion engine, a battery, an electric machine, and a controller. The vehicle is operable in a primary electric vehicle driving mode (EV mode) and in a hybrid electric vehicle driving mode (HEV mode). The controller is programmed to receive input from the driver representing a desired operating mode and a desired energy reservation. If the desired operating mode is HEV mode, then a state of charge (SOC) offset is established as the smaller of a maximum SOC offset and an allowable SOC offset, otherwise, the SOC offset is established based on the desired energy reservation. The vehicle is operated based on the SOC offset.

Plug-in hybrid electric vehicle battery state of charge hold function and energy management

A controller may be configured to adjust a brake apply and release detection calibration based on a detection sensitivity associated with a predicted driver start/stop intention for a vehicle and an associated confidence level indicative of a likelihood of the predicted driver intention; and perform at least one of engine startup and engine shutdown according to the adjusted brake pedal detection calibration.

Informational based engine stop/start sensitivity control for micro-HEV

An example trailer road grade estimating method includes calculating a road grade beneath a trailer vehicle based on a difference between a first estimated mass and a second estimated mass.

Estimating a trailer road grade

A method and a system for controlling camera orientation in training and exhibition systems. The method and system use a control algorithm to drive the orientation of a camera system at a determined reference velocity in order to place the aim-point of the camera system following a target aim-point in a local coordinate system. In some embodiments, the position and velocity of the target aim-point in the local coordinate system are determined based on dynamically filtered position and motion of a target object, where the position and motion of the target object are measured from a local positioning system.
