A method for operating a driver assistance system of an electrically driven motor vehicle includes providing a first and a second driving mode and setting the first driving mode or the second driving mode via an actuating device by a single user input. A first turning maneuver of the motor vehicle is set as the first driving mode and a second turning maneuver of the motor vehicle is set as the second driving mode. During the first turning maneuver, a direction of movement for each of the four wheels of the motor vehicle is respectively set via four control signals such that right side wheels of the motor vehicle and left side wheels of the motor vehicle rotate against each other. Via the driver assistance system, the motor vehicle is operated at least partially autonomously at least during the first driving mode and/or the second driving mode.

A control apparatus for a hybrid electric vehicle includes: an engine control portion for controlling an operation state of an engine; and a driving-mode control portion for controlling the vehicle so as to realize selected driving mode or modes. The driving modes include a main-drive-wheel driving mode in which a drive power is distributed to main drive wheels, and an all-wheel driving mode in which the drive power is distributed to the main and auxiliary drive wheels. When the all-wheel driving mode is selected in the main-drive-wheel driving mode with the engine being in a stopped state, the engine control portion is configured to maintain the stopped state of the engine until completion of switching from the main-drive-wheel driving mode to the all-wheel driving mode, and to start the engine after a predetermined operation is executed by the driver of the vehicle to drive the vehicle.

A control apparatus for a hybrid electric vehicle includes: an engine control portion for controlling an operation state of an engine; and a driving-mode control portion for controlling the vehicle so as to realize selected at least one of driving modes. The driving modes include a low-gear all-wheel driving mode and a high-gear all-wheel driving mode. In a case in which the low-gear all-wheel driving mode is selected in the high-gear all-wheel driving mode when the engine is in a stopped state with a vehicle power transmission apparatus being in a non-driving position that disables transmission of a drive power, the engine control portion maintains the stopped state of the engine until completion of switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode, and starts the engine after the completion of the switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode.

A vehicle with one-pedal driving mode includes a first axle having a first electric machine configured to power first wheels and a second axle having a second electric machine configured to power second wheels. A controller is programmed to, in response to a request for one-pedal driving mode, map pedal positions of the accelerator pedal to speeds of the first and second wheels such that each of the pedal positions corresponds to a driver-demanded speed of the first and second wheels, and control one or more of the electric machine so that the vehicle is propelled according to the driver-demanded speed.

A power transmission device outputting torque from a first power source and a second power source to axles, is provided with: a first shaft coupled with the first power source; a differential configured to differentially distribute the torque to the axles; a first gear set configured to drivingly couple the first shaft with the differential; a second shaft coupled with the second power source; a second gear set drivingly coupled with the second shaft; a clutch configured to receive fluid pressure to drivingly and releasably couple the second gear set with the first gear set; and a pump driven by a third power source at least independent of the first power source and the clutch to generate the fluid pressure, the pump being disposed separate from the clutch and in fluid connection with the clutch to supply the fluid pressure.

A drive-force control apparatus for a vehicle including a first drive apparatus for driving a first pair of wheels and a second drive apparatus for driving a second pair of wheels. Each of the first pair of wheels is one of front and rear wheels of the vehicle, and each of the second pair of wheels is the other of the front and rear wheels. During running of the vehicle on a wave-like road, the control apparatus reduces a drive-force share ratio of one of the first and second drive apparatuses, and to increases a drive-force share ratio of the other of the first and second drive apparatuses, wherein the one of the first and second drive apparatuses includes a weakest part that is to be damaged the most easily among parts composing the first and second drive apparatuses, by resonance caused by the running on the wave-like road.

A disconnector control device and method for an electric vehicle are provided. The disconnector control device includes a disconnector that switches wheel driving manners and a processor that recognizes a driving condition of the vehicle. The processor also acquires at least one factor related to operation of the disconnector and operates the disconnector based on the acquired at least one factor.

A four-wheel drive vehicle includes: a drive-power distribution device for distributing a drive power from an engine to main and auxiliary drive wheels with a drive-power distribution ratio between the main drive wheels and auxiliary drive wheels; and a control apparatus for controlling an electric motor such that the drive-power distribution ratio becomes a target distribution ratio value, by setting an electric-current command value for driving an electric motor. The control apparatus is configured, in a drive-power transmitted state in which the drive power is transmitted to the drive-power distribution device, to execute a command-value reduction control operation for causing the electric motor to be driven with the electric-current command value being set to a value smaller than in a drive-power non-transmitted state in which the drive power is not being transmitted to the drive-power distribution device.

A vehicle control apparatus including a driving force generation unit, a driving force distribution mechanism distributing a driving force from the driving force generation unit to a front wheel and a rear wheel, and an electronic control unit having a microprocessor and a memory. The microprocessor is configured to perform: determining whether a mode switching instruction from self-drive mode enabling a self-drive function to manual drive mode disabling the self-drive function has been input; and controlling the driving force distribution mechanism so that a driving force distribution rate of rear wheel driving force relative to front wheel driving force is a first distribution rate during driving in the self-drive mode, and thereafter so that the driving force distribution rate is a second distribution rate greater than the first distribution rate when it is determined that the mode switching instruction has been input.

A vehicle driving apparatus, configured to drive a vehicle including first and second wheels, includes first and second motors, first and second power transmission mechanisms, and a controller. The first motor is configured to generate first driving torque that rotates the first wheel. The second motor is configured to generate second driving torque that rotates the second wheel in a direction same as a direction in which the first wheel is rotated. The first and second power transmission mechanisms are configured to transmit the first and second driving torque from the first and second motors to the first and second wheels, respectively. The controller is configured to perform torque distribution control in a case where a gear rattle occurrence condition is satisfied. The torque distribution control drives the first motor to thereby decrease the first driving torque and drives the second motor to thereby increase the second driving torque.
