1. An alarm system for a motor vehicle provided with an accelerator pedal;

  • the system comprising;

    signalling means able to provide the driver with a sensorial alarm signal indicating a danger situation;

    detector means able to provide signals and/or data representing the situation outside the motor vehicle and/or the travel conditions of the vehicle itself; and

    electronic processing and control means designed to analyse the signals and/or data provided by the detector means and determine the occurrence of predetermined operating situations, such as the presence of any obstacles along the travel path of the motor vehicle, and generate, under predetermined conditions and in accordance with a predefined procedure, warning signals and/or data which can be used for activating the signalling means;

    said signalling means comprising electrically operated actuators associated with the accelerator pedal of the motor vehicle and able, when activated, to apply to said pedal a stress with predefined characteristics, which is perceivable by the driver'"'"'s foot, wherein said electronic processing and control means are designed to generate warning signals and/or data indicating a plurality of different danger levels and to 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 being designed to drive the actuator means so as to cause the application, selectively, to the accelerator pedal of;

    a continuous resistive force tending to oppose the operating force exerted by the driver;

    a sequence of force pulses with a relatively low frequency and relatively high amplitude; and

    a sequence of force pulses with a relatively higher frequency and relatively lower amplitude.
