1. A device for controlling speed reduction of a vehicle dependent upon a measured value, the device comprising:
- a vehicle having a frame that extends in a longitudinal direction that essentially coincides with the normal direction of movement of the vehicle, the vehicle having at least two wheel axles and at least two wheels on at least one of the axles;
a detector for detecting a first value in a vertical direction of the vehicle frame to detect tilt of the frame, the detector being adapted to detect the ground pressure on each of the two wheels on the at least one wheel axle and to detect the difference between the ground pressures on the two wheels as the first value;
a vehicle speed reducing device connected to the two wheels on the at least one axle;
a control unit for receiving a signal from the detector as to the first value and for sending a signal to the vehicle speed reducing device for operating the vehicle speed reducing device on the moving vehicle to counteract the tilt of the frame, the control unit being operable to operate the vehicle speed reducing device for the two wheels on the at least one axle so that a first substantially equal speed reducing force is applied to each wheel on the at least one axle in response to the first value detected by the first detector.

Abstract
To control the tilt of a multi-axle vehicle, a first detector detects the vehicle tilt and sends a signal to a control unit for causing selected vehicle speed reduction for controlling the tilt. To control the direction of the vehicle, another sensor detects the actual course of the vehicle, compares that with a desired course and sends a signal to the control unit also for causing a selected vehicle speed reduction device at the wheels for restoring the course of the vehicle. The signals for tilt and direction may be superimposed for setting the speed reduction on the wheels.

11. A device for controlling speed reduction of a vehicle dependent upon a measured value, the device comprising:
-
a vehicle having a frame that extends in a longitudinal direction that essentially coincides with the normal direction of movement of the vehicle, the vehicle having at least two wheel axles and at least two wheels on at least one of the axles; a first detector for detecting a first value in a vertical direction and substantially transverse to the longitudinal direction of the vehicle; a device in the vehicle for the setting a desired course and longitudinal direction for the vehicle; a second detector for detecting a second value corresponding to the deviation of the vehicle longitudinal direction from the desired course; a vehicle speed reducing device connected to the two wheels on the at least one axle and comprising a brake at each wheel on the at least one axle; a control unit for receiving a signal from the detector as to the first value and for sending a signal to the vehicle speed reducing device for operating the vehicle speed reducing device on the moving vehicle to counteract the tilt of the frame, the control unit being operable to operate the vehicle speed reducing device for the two wheels on the at least one axle so that a first substantially equal speed reducing force is applied to each wheel on the at least one axle in response to the first value detected by the first detector; the control unit also receiving a signal from the second detector as to the second value and for sending a signal to the vehicle speed reducing device in response to an identified deviation of the vehicle from its desired course for restoring the vehicle direction toward the direction of its desired course; the control unit also sends a signal to the vehicle speed reducing device for applying a second speed reducing force non-uniformly to the wheels on the at least one axle in response to the signal received by the control unit as to the second detected value; the control unit comprises a processor adapted for emitting a first signal corresponding to the first speed reducing force and a second signal corresponding to the second speed reducing force, and further comprises a distribution unit for activating each of the brakes in response to the first and second signals; and the distribution unit is adapted to activate the brake of one of the wheels on the at least on axle with the first force plus half of the second force and to activate the brake on the other wheel on the at least one axle with the first force minus half of the second force.
