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.
