GF42.45-W-2002MP | Intervention of stability control (SR) when there is a risk of risk of tipping, function | 3.10.02 |
MODEL 375.4, 934, 944, 954 with CODE (BB7) Stability control (SR)
Requirements
Vehicle speed > 10 km/h
Stability control (SR) is switched on, the stability control indicator lamp (INS) has gone out.
If the stability control indicator lamp flashes, switch on the stability control (SR) with the SR shutoff switch
Function
Apart from the course behavior of the tractor vehicle the vehicle dynamics control (FDR) control unit monitors deviations between the nominal and actual course, in addition to detecting tendencies to tip over, the lateral acceleration when cornering. For this purpose the vehicle dynamics control (FDR) control unit evaluates the signals of the integrated lateral acceleration sensor.
The vehicle dynamics control (FDR) control unit triggers a reduction in vehicle speed via the engine control, as soon as an exceeding of the permissible lateral acceleration with increased risk of tipping is achieved due to a cornering speed which has not been adapted.
If cornering is not stabilized in spite of reduced vehicle speed, the vehicle dynamics control (FDR) control unit initiates automatic braking of the entire semitrailer tractor combination.
The stability control indicator lamp in the instrument (INS) lights up during the reduction in speed or braking of the entire semitrailer/tractor combination.
