Abstract
A method is provided for generating an alarm signal in a vehicle for indicating that the vehicle is in the proximity of an object includes detecting a degree of proximity to the object, calculating a value of the distance (d) between the vehicle and the object, generating the alarm signal at least as an audio signal when the distance (d) is less than a predetermined first threshold value (d1), and generating the alarm signal in the form of a sequence of signal stages as the distance (d) decreases. A system is also provided for generating an alarm signal in a vehicle.
Claims14
A method for generating an alarm signal in a vehicle for indicating that the vehicle is in the proximity of an object, the method comprising:
- detecting a degree of proximity to the object;
- calculating a value of a distance (d) between the vehicle and the object;
- generating the alarm signal at least as an audio signal when the distance (d) is less than a predetermined first threshold value (d1);
- and
- generating the alarm signal in the form of a sequence of signal stages as the distance (d) decreases;
- wherein a first signal stage is generated in the form of a combination of an audio signal and a vibratory signal causing vibrations in a steering wheel in the vehicle, a second signal stage is generated in the form of an audio signal gradually increasing in volume and treble, and with a gradually decreasing level of reverb, as the distance (d) between the vehicle and the object decreases, and a third signal stage is generated in the form of a combination of a vibratory signal causing vibrations in the steering wheel and an audio signal being of higher volume than during the first signal stage.
A system for generating an alarm signal in a vehicle for indicating that the vehicle is in the proximity of an object, the system comprising:
- at least one detector unit configured for detecting a degree of proximity to the object;
- and
- a control unit configured for calculating a value of a distance (d) between the vehicle and the object and for generating the alarm signal in at least an audible manner if the distance (d) is less than a predetermined first threshold value (d1);
- wherein the control unit is configured for generating a first signal stage in the form of a combination of an audio signal and a vibratory signal causing vibrations in a steering wheel in the vehicle, a second signal stage in the form of an audio signal gradually increasing in volume and treble, and with a gradually decreasing level of reverb, as the distance (d) between the vehicle and the object decreases, and a third signal stage in the form of a combination of a vibratory signal causing vibrations in the steering wheel and an audio signal being of higher volume than during the first signal stage.
