    摘要: A method for controlling driving on a hill of an all-wheel drive vehicle, wherein vehicle acceleration is determined and the gravitational acceleration is measured. To improve the accuracy of the determination of the vehicle reference speed in all-wheel drive vehicles, the method comprises the following steps: determining the acceleration at the secondary axle (Tc4wdHaAcc) from one or both of the two wheel speeds, determining the deviation (Slope) between the acceleration at the secondary axle (Tc4wdHaAcc) and the measured acceleration (LoSenAcc), filtering the determined deviation (SlopFilt) with a time constant (T1Slope), comparing the deviation (Slope) with the filtered deviation (SlopFilt), determining driving situations representing the conditions ‘traction slip control is active’ or ‘traction slip control is not active’, and determining the slope in dependence on the comparison result and the driving situation.

    摘要: A method of improving the control performance of a traction slip control system so that faulty control activations of the TCS control system are prevented in critical situations such as driving downhill. The invention concerns a method wherein a vehicle reference speed and a vehicle deceleration signal are derived from the rotational behavior of the vehicle wheels and wherein a vehicle deceleration signal is obtained by way of a longitudinal deceleration sensor. The course of the two deceleration signals is compared and analyzed for detecting stable or unstable wheel rotational behavior. Preferably a difference signal is formed indicating the difference between the two deceleration signals. The difference signal is evaluated by a multistage filter arrangement.

    摘要: Disclosed is a method and a computer program product for compensating for gradient influence when determining a reference velocity. The method includes determining a controller nominal torque (MRnominal) in a vehicle controller (1) from at least one actual wheel speed (vwheel-actual) and one predefined nominal wheel speed (Vwheel-nominal), determining a feedback torque (Mfeedback), which is proportional to an estimated roadway gradient ({dot over (ω)}wheel−{dot over (ω)}longit.), calculating an engine nominal torque (MMnominal) from the controller nominal torque (MRnominal) and the feedback torque (Mfeedback), and sending the engine nominal torque (MMnominal) to a vehicle controlled system (2) for determining the actual wheel speed (vwheel-actual) from the engine nominal torque (MMnominal).
