摘要： A device for estimating a friction coefficient between a road surface and an automotive tire through determination of a steering torque during a steering maneuver of a slow-rolling or stationary vehicle includes a computer configured for constructing a brush model for a description of the steering torque across a contact patch between the tire and road surface. The steering torque is a torque acting on a steering axis required to overcome resistance to tire twisting on the road surface at a wheel velocity and a steering rate. The steering torque depends on a tire brush vertical load distribution and relative motion of tire brushes and the road surface. The device further includes sensors for measuring the wheel velocity and the steering rate and mechanism for measurements or estimation of the steering torque. The friction coefficient is estimated based on the measurements or estimation of the steering torque and the brush model.

摘要： Provided is a travel evaluation method of making an evaluation related to travel of a vehicle capable of traveling in a leaning position, the method including: obtaining a tire force which is an external force exerted on a wheel of the vehicle from a ground surface; and deriving an evaluation index related to travel of the vehicle. The evaluation index includes a positive evaluation index as a rating of a positive evaluation related to travel of the vehicle. In deriving the evaluation index, the positive evaluation index is set higher as the tire force increases, and the evaluation index is corrected based on an influential parameter other than the tire force.

摘要： A drive device for an all-wheel drive, two-track motor vehicle, in the drive train of which a first motor vehicle axle and, via a center clutch, a second motor vehicle axle are driven permanently by a drive assembly in driving operation. In the closed state of the center clutch, the second vehicle axle is engaged with the drive train, and, in the open state of the clutch, the second vehicle axle is decoupled from the drive train. In a driving situation with engaged all-wheel drive as well as with axle friction coefficients of varying size, a greater wheel torque can be taken up at the vehicle axle with a large axle friction coefficient than at the vehicle axle with a small axle friction coefficient, and a control instrument is provided, which, for engine torque limitation, limits the drive assembly to a maximum allowed engine torque.
