A method for controlling power consumption of a compressor of an automotive vehicle climate system may include identifying an energy source providing energy to power the compressor and selecting an operating parameter of the climate system based on the identified energy source to control power consumption of the compressor.

Automotive vehicle and method for controlling power consumption of a compressor therein

A system and method for controlling the electrical power consumption of an accessory device. A power transmission unit is adapted to generate electrical power. The system comprises a first controller, a current sensor and a second controller. The first controller is adapted to control the operation of the accessory device. The current sensor is configured to measure an amount of current being charged and discharged to and from the battery and generate a signal that corresponds to the measured amount of current charged and discharged to and from the battery. The second controller is configured to receive the signal from the current sensor and generate flag signal in response to detecting that current is being charged to the battery. The first controller is further adapted to control the accessory device to consume increased power from the electrical power generated by the power transmission unit in response to the flag signal.

Method and apparatus to control electric power consumption

A method for controlling a powertrain for a hybrid electric vehicle having an engine and a motor and gearing for establishing power flow paths from the engine and the motor with common gear elements to vehicle traction wheels. An engine power bias is applied to an engine power command and a bias to a motor torque command to avoid an operating mode in which motor torque is at or near zero, whereby gear rattle due to torque disturbances is avoided.

Method for reducing gear rattle in a hybrid electric vehicle powertrain

A method and system for limiting motor performance in a hybrid electric vehicle system. During a condition in a primary drivetrain, the method limits performance of an electric motor used in an auxiliary drivetrain to control energy consumed from a battery in the auxiliary drivetrain. A calculation or measurement is made to determine available battery energy remaining in the battery after the condition. The performance of the electric motor is then limited based on the available battery energy.

System and method for operating an electric motor by limiting performance

An automotive climate control system includes an evaporator, a variable speed compressor and a controller. The controller is configured to periodically alter a previous target evaporator temperature at a selected rate to generate a current target evaporator temperature, select a target compressor speed based on a difference between an actual evaporator temperature and the current target evaporator temperature, and command the compressor to operate at the target compressor speed.

Automotive climate system and method of controlling same

A method is disclosed for enhancing reverse driving torque in a hybrid electric vehicle powertrain in which an electric motor is used for providing forward driving torque as well as reverse driving torque. An electric generator, functioning as a motor, supplies an added reverse driving torque using a gearset in which the engine provides a reverse driving reaction torque for the gearset.

Method for controlling a hybrid electric vehicle powertrain with divided power flow paths

A system and method for controlling cycling of high voltage contactors is provided. In one embodiment, the method includes generating a first contactor command and activating the contactor in response to the first contactor command. A timer is initiated upon generation of the first contactor command. The method also includes determining whether a second contactor command should be generated subsequent to the generation of the first contactor command. The method further includes activating the contactor in response to the second contactor command being generated when the timer has expired.

System and method for controlling cycling of a vehicle contactor

A parallel hybrid electric vehicle powertrain and control method wherein an internal combustion engine and an electric motor system define a split power operating mode, a generator drive mode and a parallel power mode. Provision is made, when the motor is inoperable, for preventing discharge of a battery in the electric motor system when the battery state-of-charge is low and for delivering power from the battery when the battery state-of-charge is greater than a predetermined value.

Controller and control method for a hybrid electric vehicle powertrain

A method and system for controllably transferring energy from a high voltage bus to a low voltage bus in a hybrid electric vehicle. A vehicle system controller controls a DC/DC converter coupled between the high voltage bus and the low voltage bus to control the transfer of energy therebetween.
