An over actuated system capable of controlling wheel parameters, such as speed (e.g., by torque and braking), steering angles, caster angles, camber angles, and toe angles, of wheels in an associated vehicle. The system may determine the associated vehicle is in a rollover state and adjust wheel parameters to prevent vehicle rollover. Additionally, the system may determine a driving state and dynamically adjust wheel parameters to optimize driving, including, for example, cornering and parking. Such a system may also dynamically detect wheel misalignment and provide alignment and/or corrective driving solutions. Further, by utilizing degenerate solutions for driving, the system may also estimate tire-surface parameterization data for various road surfaces and make such estimates available for other vehicles via a network.

In order to protect the drivetrain, the protection device has a sensor device and a control device. The sensor device is designed to detect a rolling movement of the motor vehicle counter to the selected direction of travel of an engaged gearspeed of the automatic transmission, and the control device is designed to control a brake system of the motor vehicle as a function of the detected rolling movement, in order to limit a rolling speed of the motor vehicle counter to the selected direction of travel to a maximum speed.

The present invention obtains a controller capable of improving safety of a motorcycle.

The controller that controls vehicle body behavior of the motorcycle includes: an acquisition section that acquires trigger information generated in accordance with peripheral environment of the motorcycle; and an execution section that initiates a control mode making the motorcycle execute an automatic brake operation in accordance with the trigger information acquired by the acquisition section and makes the motorcycle generate a braking force. The acquisition section further acquires seat load information that is information of a load received by a seat of the motorcycle, and the execution section changes the automatic brake operation, which is executed in the control mode, in accordance with the seat load information acquired by the acquisition section.

An object of the invention is to realize an M+ control which is suitable to a driving scene without depending on pedal operation information of a driver. A vehicle motion control device according to the invention sets an absolute value of deceleration generated in the vehicle in a period in which the lateral motion of the vehicle is predicted to be changed from a state where the vehicle takes the lateral motion to a state where the vehicle does not take the lateral motion to be smaller than that generated in a period in which the lateral motion of the vehicle is predicted to be changed from a state the vehicle takes one of right and left lateral motions to a state where the vehicle takes the other lateral motion.

A trailer includes a battery and an axle or a tandem axle with wheels driven by way of electric motors. The battery supplies electricity to the electric motors during trailer travel, and a sensor detects forces on a coupling of the trailer in at least one of the following directions: longitudinal direction of the trailer and/or transverse direction of the trailer and/or perpendicular direction, and a controller controls the electric motors, so that a minimum and/or a maximum limit value is adhered to.

A controller and a control method of a motorcycle brake system including a brake operator, a wheel braking assembly, and a controller. The controller is configured to perform a lean angle obtainment step during turning, and perform a positive gradient setting step. The positive gradient corresponds to the lean angle obtained. The controller is also configured to initiate a braking force suppression operation in states where the motorcycle makes a turn and increases input to the brake operator. This operation is executed to increase braking force generated by the wheel braking assembly in a smaller positive gradient of hydraulic pressure in a wheel cylinder than a positive gradient of hydraulic pressure in a master cylinder when the braking force on the wheel depends only on the input to the brake operator. The braking force suppression operation is initiated in the positive gradient when an initiation reference is satisfied.

A vehicle includes a propulsion system configured to selectively drive at least one wheel of a plurality of wheels, a brake system configured to selectively brake at least one wheel of the plurality of wheels, and a dig lock controller in signal communication with the propulsion system and the brake system. The dig lock controller is configured to, based on a driver request, selectively perform a vehicle rotating dig lock operation by braking one wheel of the plurality of wheels while driving at least one other wheel of the plurality of wheels to move the vehicle laterally about a pivot point at least partially defined by the braked wheel.

A vehicle behavior control device is equipped with an other vehicle detection unit that detects another vehicle, a collision prediction unit that predicts that the other vehicle will collide with a side surface of a user's own vehicle, a physical quantity determination unit that determines a physical quantity relationship between relative physical quantities of the other vehicle and the user's own vehicle, and a brake control unit that is capable of individually and independently controlling brakes corresponding to respective vehicle wheels and that causes a braking force of the brakes on a collision side and a braking force of the brakes on a non-collision side to differ from each other, in accordance with the physical quantity relationship determined by the physical quantity determination unit, in the case that a collision is predicted by the collision prediction unit.

A control device includes an additional deceleration calculation unit that calculates an additional deceleration (G×add) to be applied to the vehicle based on the steering angle, a target control amount calculation unit that calculates the control amount for the vehicle behavior changing device based on the additional deceleration, a rough road level calculation unit that calculates a rough road level of a road based on a wheel speed, and a control amount correction unit that corrects the control amount based on the rough road level, the rough road level calculation unit being configured to correct the wheel speed so as to remove a change thereof caused by the cornering maneuver of the vehicle, and to calculate the rough road level by using the corrected wheel speed.

A vehicle control system, includes: a travel control unit configured to generate a first control signal for controlling a direction control device of a vehicle to make the vehicle travel along a road shape; a stability control unit configured to generate a second control signal for controlling the direction control device to stabilize behavior of the vehicle when the behavior of the vehicle is in a prescribed unstable state; and an arbitration unit configured to receive the first control signal and the second control signal and to output at least one of the first control signal and the second control signal to the direction control device. When the arbitration unit is receiving the second control signal, the arbitration unit reduces a control amount corresponding to the first control signal.
