Techniques for identifying certain signals sent over the CAN bus between components of a vehicle are provided herein. Specifically, certain testing maneuvers designed to engage the component of interest are provided to a technician for performing on the vehicle. The messages can be captured from the CAN bus and analyzed, using supervised machine learning algorithms, to isolate the message ids and the byte numbers so that the values of the component of interest may be observed for determining performance metrics. Once identified, these performance metrics may be used to compare with other vehicles or improve the design and performance of the vehicle.

Automotive can decoding using supervised machine learning

Systems and methods for improving operation of a hybrid vehicle driveline are presented. In one example, a margin torque for closing a torque converter clutch is adjusted responsive to a state of engine operation.

Systems and methods for operating a torque converter clutch

Systems and methods for improving operation of a hybrid vehicle driveline are presented. In one example, pressures applied to two different clutches are coordinated such that a pressure boost phase of a driveline disconnect clutch does not occur at a same time as a pressure boost phase of a transmission shifting clutch.

Systems and methods for improving vehicle driveline operation

Systems and methods for operating a vehicle that includes a manual transmission are presented. In one example, a speed rate of change of a driveline torque source is adjusted during a shifting of gears of the manual transmission responsive to a gear that is being disengaged and a gear that is being engaged during the shifting of gears. The torque source may be an electric machine and/or an internal combustion engine.

Systems and methods for operating a hybrid vehicle with a manual shift transmission

A system and method for controlling a hybrid vehicle having an engine selectively coupled by an upstream clutch to an electric machine, which is selectively coupled by a downstream clutch to a step-ratio transmission, include at least one controller programmed to control the engine and the electric machine in response to entering a lash zone in anticipation of a wheel torque reversal to adjust a gain applied to an active motor damping torque controller to reduce driveline oscillations and backlash.

Engine and motor control during wheel torque reversal in a hybrid vehicle

A powered sliding platform assembly may include an actuator, a platform, and a controller. The platform may have a rail defining first and second openings configured to receive a pin of an actuator. The actuator and the rail may be arranged such that while the platform moves between extended and retracted positions, the pin rides along the rail between the openings. The controller may be programmed to, in response to a signal indicative of an object being proximate the platform, inhibit movement of the platform.

Powered sliding platform assembly

A control strategy is provided for a hybrid vehicle that will increase drivability during low or decreasing driver demands. Coordination between shifting the transmission and stopping or (non-demand) starting of the engine can increase drivability. The vehicle includes a motor/generator with one side selectively coupled to the engine and another side selectively coupled to the transmission. The control strategy acts when an engine start or stop is requested while driver demand is decreasing and a shift of the transmission is demanded. To inhibit these events from proceeding simultaneously, the control strategy delays the engine from starting or stopping until the transmission has finished shifting, or vice versa.

Coordinating non-demand engine start and stop with gear shift

A vehicle includes a traction battery and a controller. The controller, in response to termination of current flow from the traction battery to a tool that is plugged in to the vehicle that results in shutting down of the tool, actuates a switch such that current resulting from the shutting down flows from the tool to the traction battery for regenerative energy capture.

Absorbing power down energy of an external motor device in a power generation vehicle

A vehicle includes an engine and an electric machine coupled to a gearbox through a torque converter. The vehicle includes a controller programmed to command an engine torque and an electric machine torque to achieve a predetermined positive torque at the input of the torque converter when a driver demand torque at the torque converter input decreases to fall within a range between the predetermined positive torque and a predetermined negative torque.

System and method to prevent driveline float in lash region

A vehicle includes a clutch to couple a motor and transmission, and a controller that, in response to a regenerative braking request and a temperature being within a first range, partially capacitizes the clutch for regenerative torque transfer therethrough with slip, and in response to another regenerative braking request and the temperature being within a second range less than the first, fully capacitizes the clutch prior to regenerative torque transfer therethough to preclude slip.

Temperature based clutch control

Systems and methods for improving hybrid vehicle cooling are presented. In one example, an electric pump may supply transmission fluid to a transmission and a driveline integrated starter/generator to cool, operate, and lubricate driveline components. The electric pump may be selectively operated to conserve energy and to supply driveline cooling when driveline cooling may be desirable.

Methods and systems for improving hybrid vehicle cooling

A vehicle includes a powertrain and a controller. The powertrain includes a transmission torque converter having a bypass clutch disposed between an electric machine and a drive wheel. The controller is programmed to adjust a closed-state torque capacity of the bypass clutch according and in proportion to the greater in absolute value of a negative impeller torque command to the torque converter and a negative regenerative braking torque request.

Hybrid vehicle clutch control system

A hybrid vehicle includes an engine, an electric machine selectively coupled to the engine, a transmission having a torque converter impeller coupled to the electric machine and a torque converter clutch configured to selectively couple the impeller to a turbine, and a controller configured to control pressure of the torque converter clutch responsive to estimated clutch capacity, which is adjusted by the controller to equal impeller torque responsive to impeller speed exceeding turbine speed during clutch disengagement. A model of estimated torque converter clutch capacity may be stored in memory and adapted to actual clutch capacity by applying a gain or offset determined during opening of the clutch.

Hybrid vehicle control using adaptive transmission torque converter clutch capacity estimation

A vehicle includes a powertrain, an electric machine, a battery, and a controller. The powertrain is configured to transfer motive power to the electric machine to charge the battery during regenerative braking. The controller programmed to, in response to a decreasing demanded powertrain output torque, adjust a regenerative braking torque limit based on an anti-jerk torque schedule, generate an actual regenerative braking torque based on system constraints, and limit the actual regenerative braking torque to the regenerative braking torque limit.

Control system for regenerative braking in a hybrid vehicle

A vehicle includes an engine and an electric machine coupled to a gearbox. A controller is programmed to predict, at an onset of a shift, a supplemental torque profile to fill a torque hole expected during the shift and an available electric machine torque during the shift. The controller is further programmed to, in response to the supplemental torque profile exceeding the available electric machine torque during the shift, operate the engine from the onset to achieve a torque reserve in anticipation of increasing the engine torque.
