Abstract

Data concerning a pressure between driver and the seat (110) of vehicle and data concerning a vibration of seat or vehicle are acquired using acceleration sensor (120). A frequency response between the concerned data is determined for indicating a muscular impedance. The determined frequency response is compared with a reference frequency response and the deflection in the frequency responses is analyzed for indicating whether the driver is in fatigue condition. Independent claims are included for the following: (1) driver condition monitoring system; and (2) computer executable program comprising code for performing driver condition monitoring method.
