Abstract:
The present invention relates to a method for running of a vehicle, such that said vehicle comprises a combustion engine which can selectively be connected to at least one driveshaft (104, 105) to deliver driving force to said driveshaft (104, 105) for propulsion of said vehicle, said vehicle can be run in a first mode (Ml) in which it is run with said engine connected to said driveshaft (104, 105) and in which fuel supply to said engine is substantially shut off, in a second mode (M2) in which it is run with said engine disconnected from said at least one driveshaft (104, 105). In a situation where the vehicle is or will be travelling on a downgrade the method comprises - determining whether running said vehicle on said downgrade in said first mode (Ml) will result in a speed increase for said vehicle, and - running the vehicle in said second mode (M2) if it is determined that running it in said first mode (Ml) would result in a speed increase for said vehicle (100).
Abstract:
The present invention relates to a method and a system for estimating a road gradient a by using a sensor fusion. The present invention detects whether at least one dynamic process is affecting said vehicle. Estimation of said gradient a is then conducted by means of the sensor fusion by joint weighting of at least two input signals to said sensor fusion. The at least two input signals comprise an input signal based on an accelerometer and an input signal based on at least one force equation. At least one of said at least two input signals and/or at least one weighting parameter for the sensor fusion are determined on the basis of said detection of whether said at least one dynamic process is affecting the vehicle.
Abstract:
A wading sensor for a vehicle comprises an ultrasonic parking distance control. An embodiment detects wading by sensing the difference in the settling time of the diaphragm of a transmitter/receiver, in water and in air. Other embodiments are disclosed.
