Abstract:
1. An alarm system for a motor vehicle provided with an accelerator pedal; the system comprising: said signalling means comprising electrically operated actuators associated with the accelerator pedal of the motor vehicle for, when activated, applying to said pedal a stress with predefined characteristics, which is perceivable by the driver's foot, wherein said electronic processing and control means generate at least one of warning signals and data indicating a plurality of different danger levels and operate said actuator means in a corresponding plurality of different modes, so as to apply to the accelerator pedal correspondingly different perceivable stresses, said processing and control means driving the actuator means so as to cause the application, selectively, to the accelerator pedal of: the system further comprising angular position sensor means associated with the accelerator pedal and the abovementioned rotating member, said sensor means being connected to said electronic processing and control means to control the movement of the rotating member based on a predefined mathematical model representing the system comprising the accelerator pedal and the mechanical part of said actuator means.
