Abstract
A method and a system for limiting an engine torque of vehicles to a maximum value. In the method, signals representing wheel torques from wheel sensors at the drive train are acquired, the wheel torques, differentiated according to driving situations which can have a harmful influence on the transmission, differential or torque converter, then being checked for a wheel-torque value which is too high. If too high a value is found, the engine torque is limited or reduced.
Claims9
A method for limiting an engine torque of a vehicle, the method comprising, prior to the limiting:
- detecting signals, representing instantaneous wheel torques, with the aid of wheel sensors in a drive train of the vehicle;
- and
- performing a differentiated recognition of the instantaneous wheel torques which are too high for various driving situations.
A system for limiting an engine torque of a vehicle, comprising:
- wheel sensors for supplying signals, for respective wheels of the vehicle;
- an evaluation unit for receiving the signals, determining wheel torques as a function of the signals and supplying the wheel torques;
- a limiting unit;
- and
- a recognition unit for receiving the wheel torques, carrying out an analysis for a specific driving situation and activating the limiting unit when the recognition unit determines that a limiting is necessary.
