influence of the slipping of the driving wheels

Wheel-slip control, power limiting and variable acceleration functions are provided.

Described is a method of improving vehicle control when braking, in which target slip values are determined and adjusted with a wheel-slip controller.

Vehicles shall be fitted with wheel-slide devices to control the sliding of wheels in the event of reduced adhesion between wheel and rail

Drive imagery showed the surface material crumbling and causing the wheels to slip.

Operating characteristics of the train such slid wheel events and handling impacts can be monitored and stored.

But under hard acceleration, or if the front wheels begin to slip, as much as 50 percent of that power can be sent to the rear wheels.

When the slip ratio of the front wheels (2) or the rear wheels (3) is higher than a threshold value, the controller determines whether or not the vehicle speed is higher than or equal to a reference speed.

If the slip angle of the rear wheels exceeds that of the front, the vehicle is said to be oversteering.

If the rear slip angle is greater than the front, the vehicle is said to over-steer.

If the slip angle of the front wheels exceeds that of the rear, the vehicle is said to be understeering.

An integrated multiplate clutch ensures additional traction and optimum directional stability as soon as the wheels show any sign of slipping.

Vehicles shall be fitted with wheel-slide devices to control the sliding of wheels in the event of reduced adhesion between wheel and rail,

The following parameters are estimated: longitudinal vehicle speed VX, longitudinal vehicle acceleration VX, wheel-slip values μ, longitudinal forces FB and transverse speed VY.

It facilitates the change from direct to inverse transmission, without requiring the use of tools, and it achieves a clutch effect through the sliding of the wheels in relation to the tubes.
