Method For Estimating The Mass Of A Vehicle Which Is Being Driven On A Road With A Varying Gradient And Method For Estimating The Gradient Of The Road Upon Which The Vehicle Is Being Driven
First Claim
1. Method for estimating the mass of a vehicle which is being driven on a road with varying gradient, comprising the following method steps:
- measurement of the vehicle'"'"'s speed for generating input data for a calculation device;
measurement of a variable which comprises a longitudinal force acting on the vehicle for generating input data for a calculation device;
characterized in that said calculation device generates an estimate of the weight of the vehicle by means of a recursive process by using a statistical filter using said input data comprising the speed of the vehicle and said variable and a statistical representation of a road with varying gradient.
