A method for determining whether the driver of a vehicle is holding the steering wheel includes steps of repeatedly determining (S) the steering wheel angle, repeatedly determining (S) an error value based on a current determined steering wheel angle value and a previously determined steering wheel angle value; comparing (S) a determined current error value with previously determined error values to determine a correlation between the error values; determining (S) that the driver is holding the steering wheel if the correlation between the error values is above a threshold value or if the driver is not holding the steering wheel if the correlation between the error values is below a threshold value. Also, a system for determining whether the driver of a vehicle is holding the steering wheel by performing the method. Also a computer program and a computer program product for practicing the method.

Method and system for determining whether the driver of a vehicle is holding the steering wheel

A method for guidance of driver behavior during driving of a vehicle () in hilltop driving: the steps of continuously determining topography along the vehicle's itinerary for determining a profile of the vehicle's speed (v); presenting (S) the vehicle driver with suggestions for action concerning the driving of the vehicle for a desired reduction of fuel consumption, the action includes reduced power mobilization before a hilltop transition. A profile of the vehicle speed (v) is determined as a result of the action, whereby the step of presenting (S) the vehicle's driver with suggestions for said action, is subject to consideration to subconditions. The subconditions include requirements in response to reduced power mobilization, the speed of the vehicle () relative to a reference level (v) should: drop by a predetermined largest amount before the hilltop transition; drop by a predetermined smallest amount before the hilltop transition; reach or exceed the reference level (v) after the hilltop transition. Also disclosed is a system for guidance of driver behavior during driving of a vehicle in hilltop driving, a motor vehicle practicing the method and a system and a computer program for executing the method.

Method (), calculation device () and display () for causal analysis of the fuel/energy consumption in a vehicle (), which is driven by a driver (): Division () of the vehicle's fuel/energy consumption over a number of fuel/energy consumers, calculation () of the subdivided () fuel/energy consumers' fuel/energy consumption in a calculation device (), and visualization () of the subdivided () fuel/energy consumers' calculated () fuel/energy consumption, on a display (), which is controlled by the calculation device ().

Fuel consumption analysis in a vehicle

A method for assessment of driver behavior during driving by continuously characterizing (S) the driver's braking processes by determining (S) the cause of a chosen braking process such as a camera view, map and location data, evasive maneuvers, ambient conditions, road conditions, and assessing (S) whether the chosen braking process is the appropriate response. Also a system for assessment of driver behavior during driving, a motor vehicle with the system and a computer program for performing the process.
