Abstract:
A computer-implemented method includes displaying a plurality of power consuming and producing vehicle components. The method also includes determining what components are currently consuming power and what components are currently delivering power, and to what magnitude the power is flowing between components. The method additionally includes displaying one or more arrows showing a powerflow from at least one power producing component to at least one power consuming or producing component. The method further includes displaying an indicia indicating the magnitude of the powerflow associated with the one or more arrows. Also, the method includes, for at least one power consuming component, displaying a gauge relating to a level of power being consumed by the at least one power consuming component.
Abstract:
A hybrid system includes a transmission control module, a power source, a transmission, and a drive train. The transmission control module partially operates the hybrid system and receives operating information from various components of the system, calculates power losses in the drive train, and calculates the driving torque needed to reach a target power profile determined from a driver's input.
Abstract:
A control apparatus for a vehicle may include an engine, a fuel tank, a feed pump, a pressure sensor, a motor and an electric storage apparatus. The feed pump feeds the fuel to a port injection valve. The pressure sensor detects a fuel pressure that is fed to the port injection valve. The motor performs cranking of the engine at start time of the engine. The control apparatus includes an ECU. The ECU controls the feed pump based on a detection value of the pressure sensor and controls the motor in order to start the engine. The ECU controls the feed pump and the motor such that the electric storage apparatus feeds electric power to the motor in preference to the feed pump, when an electric power that the electric storage apparatus is able to output at the start time of the engine is less than a determination threshold.
Abstract:
A method of forcibly charging a high-voltage battery using a motor and a Hybrid Starter Generator (HSG) is provided. The method forcibly charges the high-voltage battery with maximum charging power using the motor and the HSG simultaneously. Particularly, the method includes calculating maximum chargeable power for the high-voltage battery using three dimensional (3D) maximum charging power maps of the motor and the HSG and adjusting maximum charging power using energy integration during forced charging using the motor and the HSG simultaneously. Additionally, excessive temperature prevention logics are applied for protecting the motor and the HSG from an excessive temperature in a forced charging mode.

A vehicle includes a powertrain having an engine and an electric machine (M/G) connected by an upstream clutch, and a gearbox connected to the M/G by a torque converter. A controller is configured to, in response to a Park or Neutral gear selection and an electrical power request from the M/G, operate the engine at an engine speed and an engine torque based on the request and M/G speed and torque for improved powertrain efficiency. A method is provided for controlling a vehicle. In response to a Park or Neutral gear selection and an electrical power request from the M/G, the engine is operated at an engine speed and an engine torque based on the request and M/G speed and torque for improved powertrain efficiency.

Abstract:
An engine, a transmission unit which is connected to the engine and is shifted by an engagement apparatus, and a differential unit which connects the transmission unit and a drive wheel are included. The differential unit includes a first rotary element connected to an output element of the transmission unit, a second rotary element connected to a first rotary machine, and a third rotary element connected to the drive wheel. When an output from the first rotary machine is limited, the engagement apparatus is slipped and an operation point of the engine is changed. The change of the operation point can cause an increase in torque of the engine.
Abstract:
An engine start control apparatus/method for a series hybrid vehicle is provided. The vehicle includes an engine, a motor/generator, a battery unit chargeable with electric power generated by the motor/generator, and a traction motor operable to receive electric power from the battery unit or motor/generator. A demanded power level is determined based on a sensed vehicle speed level and a sensed accelerator pedal position. A discharge capacity level of the battery unit is determined in terms of a power level available from the battery unit. The engine starting procedure is initiated upon the determined demanded power level reaching a predetermined relationship with the determined discharge capacity level so that the motor/generator is enabled to generate electric power before the determined demanded power level reaches the determined discharge capacity level.
Abstract:
A vehicle and a method of controlling the vehicle are provided. The vehicle controller is configured to (i) in response to the user interface receiving input selecting an electric-only operating (EV) mode, disable the engine such that the vehicle is propelled by the electric machine, (ii) in response to the user interface receiving input overriding EV mode, re-enabling the engine for a predetermined time period. A vehicle is provided with a controller. In response to input selecting an electric-only operating (EV) mode, an engine is disabled such that the vehicle is propelled by an electric machine. In response to user power demand being greater than power available during the EV mode, a prompt is generated inquiring whether to override the EV mode. In response to user confirmation to override the EV mode, the engine is re-enabled to satisfy the user power demand.
