Abstract

A two-wheeled vehicle having a first spring device of a front wheel and a second spring device of a rear wheel, and at least one acceleration and rate-of-rotation sensor, which are situated on a vehicle frame and are operationally connected to a control device, wherein the first and the second spring device are provided with a spring travel sensor in each case, which are operationally connected to the control device.

First claim

1 - 10 . (canceled)

11 . A control unit for use on a two-wheeled vehicle, the two-wheeled vehicle including a first spring device of a front wheel, a second spring device of a rear wheel, and at least one acceleration and rate-of-rotation sensor, which are situated on a vehicle frame , wherein the control unit has a first and a second spring sensor, which are situated on the first and on the second spring device, respectively, wherein the control unit is designed so that at least one of: i) a drive torque control at the rear wheel is activated only when a maximum spring travel at the front wheel has been reached, and ii) a brake force control at the front wheel is activated only when a maximum spring travel at the rear wheel has been reached, wherein an online calibration for determining the available spring travels takes place in a position in which the acceleration and rate-of-rotation sensor outputs an angle of essentially zero in relation to the direction of the earth's gravitational force.

12 . The control unit as recited in claim 11 , wherein at least one of the drive torque control and the brake force control is activated before a respective maximum spring travel is reached.

13 . The control unit as recited in claim 11 , wherein at least one of the brake force control and the drive torque control is carried out as a function of a coefficient of friction of at least one of the front wheel and the rear wheel.

14 . The control unit as recited in claim 11 , wherein at least one of the brake force control and the drive torque control is carried out as a function of limits of lateral guidance forces of at least one of the front wheel and the rear wheel.

15 . A two-wheeled vehicle having a first spring device of a front wheel, a second spring device of a rear wheel, and at least one acceleration and rate-of-rotation sensor, which are situated on a vehicle frame, operationally connected to a control unit, the first and the second spring device respectively provided with a spring travel sensor, which are operationally connected to the control device, the control device designed so that at least one of: i) a drive torque control at the rear wheel is activated only when a maximum spring travel at the front wheel has been reached, and ii) a brake force control at the front wheel is activated only when a maximum spring travel at the rear wheel has been reached, wherein an online calibration for determining the available spring travels takes place in a position in which the acceleration and rate-of-rotation sensor outputs an angle of essentially zero in relation to the direction of the earth's gravitational force.
