The vehicle attitude control system for controlling the attitude of a vehicle in which a road wheel suspension is configured such that a roll axis of the vehicle inclines downwardly in a forward direction. The vehicle attitude control system includes: a road wheel speed sensor operable to detect a road wheel speed; a brake actuator operable to apply a braking force to each road wheel of the vehicle; and a brake control device operable to cause the brake actuator to generate the braking force, based on a detection signal of the road wheel speed sensor, wherein the brake control device executes vehicle attitude control of applying a first braking force to the inner rear road wheel, based on a difference in road wheel speed between an inner and an outer rear road wheels of the vehicle being turning, during turning of the vehicle.

A method for controlling a hydraulic brake system where a hydraulic fluid is displaced in the direction of at least two-wheel brakes by means of a brake cylinder. One of the at least two-wheel brakes is at least partially hydraulically isolated from the brake cylinder in order to adapt the at least two-wheel brakes with regard to their hydraulic braking force to an incipient or present wheel load distribution. In addition or alternatively, in the method, it is furthermore the case that at least one volume fraction of the hydraulic fluid is displaced between the at least two wheel brakes in order to adapt the at least two wheel brakes with regard to their hydraulic braking force to a changing wheel load distribution over the course of the braking process and/or to a changing generator braking torque over the course of the braking process.

A method for preventing a forward flip-over or a flip-over about the vehicle transverse axis of a single-track motor vehicle, during a braking action of its front wheel. In the method, a lift-off indicator parameter is ascertained, which represents the flip-over hazard by a rear wheel at risk of lifting off or already having lifted off the ground surface, and the braking force at the front wheel is reduced as a function thereof to prevent a flip-over.

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.

A brake fluid pressure control device for vehicles with bar handle, includes: an acceleration acquiring unit which is configured to acquire acceleration that occurs in the vehicle; and a control unit which is configured to judge a probability of occurrence of a rear-wheel lift based on the acceleration acquired by the acceleration acquiring unit, and which is configured to perform a pressure reduction control on a front wheel brake when judging that the occurrence of the rear-wheel lift is probable, the control unit which is configured to adjust a degree of pressure reduction of the pressure reduction control based on a differentiation value of the acceleration acquired by the acceleration acquiring unit.

An undercarriage having an undercarriage leg carrying at least one stub, the stub being provided with a hollow element. An onboard device comprises a bar and at least one measurement unit. The measurement unit comprises two pieces of equipment, one of the pieces of equipment comprising a measurement member and one of the pieces of equipment comprising a wall. One of the two pieces of equipment is secured to the bar and one of the two pieces of equipment is secured to the hollow element, the onboard device including a test system. The test system has movement means for imparting, on request, relative movement between the pieces of equipment in order to detect a potential malfunction and in order to generate an alert if a malfunction is detected.

A tipping avoidance system configured to modify operation of a collision avoidance system. The tipping avoidance system may include a payload determination system configured to generate a payload signal, and a load position determination system configured to generate a load position signal. The tipping avoidance system may also include a tipping avoidance controller configured to receive the payload signal and the load position signal, and determine, based at least in part on the payload signal and the load position signal, a minimum stopping distance at or above which the machine will not tip due at least in part to deceleration of the machine from a travel speed to a stopped condition. The tipping avoidance controller may be configured to communicate with a braking controller, such that the braking controller adjusts a stop triggering distance based at least in part on the minimum stopping distance.

Provided is a wheel load estimation device configured to acquire wheel speed information of each wheel included in a vehicle from a wheel speed sensor provided in the vehicle; to calculate a front-rear load ratio and a left-right load ratio based on the wheel speed information; and to calculate a wheel load ratio expressing a relative wheel load between the wheels included in the vehicle, with respect to at least one wheel of the vehicle, based on the front-rear load ratio and the left-right load ratio. The front-rear load ratio is a ratio between a load applied to a front wheel of the vehicle and a load applied to a rear wheel of the vehicle, and the left-right load ratio is a ratio between a load applied to a left wheel of the vehicle and a load applied to a right wheel of the vehicle.

In a braking performance evaluation method including the steps of acquiring a tire ground contact pressure distribution, acquiring a sliding friction coefficient table, and calculating a friction force of an entire tire using a brush model having a function representing the tire ground contact pressure distribution and the sliding friction coefficient table, the step of acquiring the tire ground contact pressure distribution includes the step of acquiring a first ground contact pressure distribution on a road surface on which no water film is present via actual measurement or calculation and the step of acquiring a second ground contact pressure distribution by applying reduction in a ground contact pressure due to a water film intruded between the tire and the road surface to the first ground contact pressure distribution and using the second ground contact pressure distribution as the tire ground contact pressure distribution used for the calculating.

The invention relates to an operating method for an automatic transmission, particularly for an automatic variable-speed transmission and/or dual-clutch transmission, for a motor vehicle. The automatic transmission can be operated in a cost-effective manner, particularly with reduced component wear and increased service life, and/or the driving comfort of the vehicle can be improved such that when lifting of at least one driven vehicle wheel off the roadway during braking is detected by the operating method, then for the length of said braking process, in the event of an incomplete gear change into a gear of the transmission, the engagement of a gear is prevented and/or the beginning of a gear change into a gear of the transmission is prevented.
