A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.

A system and method for modifying the engine pull-up (EPU) logic within a hybrid vehicle based on max motor torque that accounts for the drop or change in available motor torque due to the opening/slipping of a torque converter bypass clutch during engine starts is disclosed. An engine pull-up threshold is determined from max available motor torque at a virtual impeller speed, where the virtual impeller speed is the impeller speed that would result if the torque converter bypass clutch was open/slipping and transferring the same amount of torque.

An operating strategy optimized for dynamic requirements for 48V drive systems of MHEV.

A vehicle includes a main drive unit, a sub drive unit, and a control unit. The main drive unit includes a main drive rotary electric machine. The sub drive unit includes a sub drive rotary electric machine. The control unit includes a driving force distribution ratio setting unit configured to set a driving force distribution ratio between the main driving force and the sub driving force and is configured to control the outputs of the main drive unit and the sub drive unit so that the main driving force and the sub driving force have the driving force distribution ratio set by the driving force distribution ratio setting unit. The driving force distribution ratio setting unit is configured to set the driving force distribution ratio to minimize electric power loss of the vehicle based on a vehicle speed of the vehicle and a required driving force of the vehicle.

A control system algorithm is provided for the computer control of a solid-state switching device in a Stirling-electric hybrid vehicle. The algorithm satisfies the demands for electrical energy management, regulation, allocation and distribution to the electrical system of the vehicle during the operation thereof. The control system controls the management, regulation, allocation and distribution of electrical current throughout the vehicle's electrical system in response to the commands of the vehicle operator. This includes the operation of wheel motors, electrical storage systems, the drivetrain and a plurality of other components, accessories and subsystems.

A vehicle includes a powertrain having an electric machine and a controller. The controller is programmed to, responsive to an accelerator pedal position exceeding a first threshold for a predetermined time period or a lateral acceleration of the vehicle being greater than a second threshold, transition the powertrain from a nominal driving mode to a performance driving mode. The controller is also programmed to, responsive to an increase in a steering wheel angle while in the nominal mode, maintain a power output of the electric machine at a driver demanded power defined by the accelerator pedal position. The controller is further programmed to, responsive to an increase in a steering wheel angle while in the performance driving mode, reduce a power output of the electric machine to less than the driver demanded power.

A method of automatically controlling vehicle auto-hold includes: collecting information on a vehicle traveling condition that applies when a driver operates a brake pedal while a vehicle is traveling; selecting learning data for learning on a pattern of a driver's operation from among pieces of the information collected in the collecting of the information on the vehicle traveling condition and storing the selected learning data; performing the learning on the pattern of the driver's operation based on the learning data and generating a categorization model for the pattern of the driver's operation according to a result of the learning; and determining whether or not to cause the auto-hold switch to enter an automatic operation mode while the vehicle is traveling, using the categorization model, and selectively causing the auto-hold switch to enter the automatic operation mode according to a result of the determining.

There is provided a hybrid vehicle to suppress hunting (inversion) of a drive mode in a short time. The hybrid vehicle has an engine, a motor, a battery, an air conditioning system configured to condition air in a passenger compartment, and map information, and sets a drive route from the present location to the destination, and creates a drive support plan in which one of the drive modes including CD mode and CS mode is assigned to each drive section of the drive route to perform the drive support control. The drive support plan is created based on the battery remaining capacity taking into account the power consumption of the air conditioning system. When the predetermined condition that is based on the battery remaining capacity without taking into account the power consumption of the air conditioning system is satisfied while performing the drive support control, the driving state is continued.

A controller drives a shifting actuator to move a first engagement member from an original position of a first engagement portion in one direction along a relative motion path and acquires first position information representing a first position, the first position being a position where the first engagement portion moved in the one direction contacts a second engagement portion. The controller drives the shifting actuator to move the first engagement member from the original position in the other direction along the relative motion path and acquires second position information representing a second position where the first engagement portion moved in the other direction contacts the second engagement portion. The controller calculates a center position of the first engagement portion on the relative motion path from the acquired first position information and the acquired second position information, compares the calculated center position to the original position.

A control device of a vehicle capable of traveling according to a plurality of traveling modes including a first traveling mode and a second traveling mode is provided. The control device includes a traveling mode control unit and an internal combustion engine control unit. The internal combustion engine control unit increases a rotational speed of a internal combustion engine at a predetermined increase rate as a vehicle speed increases when the vehicle is traveling in the first traveling mode. The traveling mode control unit includes a prediction increase rate acquisition unit configured to acquire a prediction increase rate, and a transition prohibition setting unit configured to prohibit transition to the second traveling mode when a transition condition is satisfied, based on the prediction increase rate acquired by the prediction increase rate acquisition unit and the increase rate.
