The invention relates to a method for controlling a drive system for an axle of a motor vehicle, wherein the drive system has at least one drive unit, a drive shaft driven by the drive unit, a first output shaft and a second output shaft, as well as a first clutch connecting the drive shaft to the first output shaft and a second clutch connecting the drive shaft to the second output shaft, and furthermore comprises a control unit for controlling the clutches, wherein the clutches are able to be operated at least at certain operating points with a micro-slip control in which a speed differential between the drive shaft and the output shaft of more than zero revolutions per minute and no more than 50 revolutions per minute is set at the respective clutch, wherein the method comprises at least the following steps: a) establishing a travel state of the motor vehicle, wherein at least the following travel states are detected: traveling straight ahead and cornering in the pull mode; b) selecting and applying a control strategy for each clutch, wherein the control strategy is different for different travel states.
CONTROL APPARATUS FOR ELECTRIC VEHICLE
A control apparatus for an electric vehicle includes a requested torque calculator, a command torque calculator, and a driving controller. The requested torque calculator is configured to calculate requested torque. The command torque calculator includes a change rate adjuster configured to adjust respective upper limit change rates of left command torque and right command torque that follow the requested torque. The change rate adjuster is configured to, on the basis of a predetermined operation of turning back a steering angle performed on a steering unit of the electric vehicle, lower the upper limit change rate of a driving wheel, serving as an inner wheel among left and right driving wheels of the electric vehicle before turning back the steering angle, than the upper limit change rate of the driving wheel, serving as an outer wheel among the left and the right driving wheels before turning back the steering angle.
Control system for a vehicle
A control system for a vehicle having a first wheel (101) arranged to be driven by a first drive source and a second wheel (101) arranged to be driven by a second drive source, wherein the first wheel and the second wheel are transversely located on the vehicle, the control system comprising a controller (102) and a monitoring device, wherein the monitoring device is arranged to monitor the power differential between the power being applied to the first wheel by the first drive source and the power being applied to the second wheel by the second drive source, wherein upon a determination that the power differential between the power being applied to the first wheel and the second wheel is greater than a predetermined value, the controller is arranged to reduce the power differential.
METHOD FOR PREVENTING ROLL-OVER OF A MOTOR VEHICLE BY MEANS OF TORQUE VECTORING
Systems and methods for preventing roll-over of a motor vehicle in the event of a transverse load change. The motor vehicle has an individual-wheel drive designed to drive a wheel that is loaded by the transverse load change independently of the at least one other wheel of the motor vehicle. One methods includes identifying a critical state of the motor vehicle in the event of a transverse load change, applying a drive torque by the individual-wheel drive to the motor vehicle wheel that is loaded by the transverse load change such that the wheel that is loaded by the transverse load change is caused to slip, and steering the motor vehicle wheel that is loaded by the transverse load change in the direction of the direction of travel such that a roll-over of the motor vehicle can be prevented.
SYSTEMS AND METHODS FOR CONTROLLING DRIVING DYNAMICS IN A VEHICLE
A system for controlling movement of a vehicle includes a user input device and computing system. The user input device dynamically controls a settings or balance of driving dynamics in a vehicle, and the user input device is configured to receive a manual input from a user. The computing system controls the settings of the vehicle driving dynamics and/or balance of the vehicle, the computing system is in data communication with the user input device and configured to change the driving dynamics balance proportionately to the manual input upon receiving an input command based on the manual input from the user input device.
BEV POWERTRAIN/STEERING CONTROLS FOR ENHANCED STABILITY ON INCLINED SURFACES
A vehicle control system may include a sensor network sensing vehicle attitude information and a controller operably coupled to the sensor network to determine, based on the vehicle attitude information, movement of a center of gravity of the vehicle relative to an axis of rotation of the vehicle. The controller may further determine a modification to a torque application of the vehicle based on the movement of the center of gravity of the vehicle relative to the axis of rotation of the vehicle.

A traveling vehicle includes a pair of left and right driving wheels, a pair of left and right motors capable of driving the pair of left and right driving wheels independently of each other, an operational amount reception section capable of receiving operational amounts respectively for the pair of left and right motors, a setting section capable of setting a period of a first control method having a predetermined first control parameter and a period of a second control method having a predetermined second control parameter, within a predetermined control cycle for controlling driving of the motors, in accordance with the operational amounts and a motor driving section capable of driving the respective motors based on result of setting made by the setting section.
VEHICLE TRAVELING CONTROL DEVICE
The steering controller calculates a target steering angle for causing the own vehicle to travel along the target course acquired by the traveling road information acquirer. The braking/driving force controller calculates a target yaw moment for correcting the positional displacement of the own vehicle from the target course. The control ratio setter sets a control ratio of cooperative control of steering control and yaw moment control based on the deviation amount of a lateral position of the own vehicle from the target course. The control ratio is set so that when the positional displacement of the own vehicle from the target course is relatively small, the ratio at which the steering control occupies is reduced, and the yaw moment control is dominant, and when the positional displacement of the own vehicle from the target course is relatively large, the ratio at which the steering control occupies is increased.
Vehicle and control method for vehicle
A monitor unit of a vehicle acquires an object left-right difference parameter corresponding to a command left-right difference parameter or corresponding to a measurement left-right difference parameter. The monitor unit compares the object left-right difference parameter and a first left-right difference threshold. If the object left-right difference parameter exceeds a first left-right difference threshold, the monitor unit limits the motive power of a first rotary electric machine and a second rotary electric machine.
Method for controlling driving force of vehicle
A method for controlling driving force of a vehicle in which driving force of the vehicle is controlled by pre-reflecting vertical load information of tires in real time during turning of the vehicle, to solve repeated occurrence of wheel slip and wheel slip control performance degradation due to roll motion, includes determining, by a controller, a basic torque command in real time based on vehicle driving information obtained while driving of the vehicle, obtaining information related to left wheel and right wheel vertical loads in real time based on information collected by the vehicle, determining a torque upper limit from the real-time vertical load information, determining a final torque command limited so as not to exceed the determined torque upper limit from the real-time determined basic torque command, and controlling operation of a driving device in accordance with the determined final torque command.
