Vehicle function impairment detection

A method comprising:

• receiving, using a receiver module, at least one radar signal;
• generating, using a control module that includes a processor that is configured to execute instruction stored in a nontransitory memory, a Fourier transformation based on the at least one radar signal;
• determining, using the control module, a presence of wave interference based on the Fourier transformation having a harmonic distortion value that is greater than a threshold harmonic distortion value;
• and
• generating, using a primary indicator module and in response to the control module determining the presence of wave interference, an indication, wherein the indication corresponds to the presence of wave interference;
• wherein:
• the primary indicator module includes at least one of a vibration module, an LED module, and an auditory alert module;
• the vibration module includes a vibration motor, a switching element, and a filtering element,
• the method further comprises:
• in response to the control module determining the presence of wave interference, providing, using the control module, an indication signal to the switching element;
• in response to the switching element receiving the indication signal, activating, using the switching element, the vibration motor;
• and
• in response to the vibration motor being activated, generating, using the vibration motor, the indication, wherein the indication is a haptic alert.

An apparatus comprising:

• a receiver module that is configured to receive, at a first location associated with at least one of (i) a user of the apparatus and (ii) a first road, at least one radar signal transmitted by at least one vehicle;
• a control module that includes a processor that is configured to execute instruction stored in a nontransitory memory, wherein the control module is configured to:
• generate a Fourier transformation based on the at least one radar signal;
• and
• determine a presence of wave interference at the first location in response to the Fourier transformation having a harmonic distortion value that is greater than a threshold harmonic distortion value;
• and
• a primary indicator module that is configured to, in response to the control module determining the presence of wave interference, generate an indication, wherein the indication corresponds to the presence of wave interference;
• wherein:
• the primary indicator module includes at least one of a vibration module, an LED module, and an auditory alert module;
• the vibration module includes a vibration motor, a switching element, and a filtering element;
• in response to the control module determining the presence of wave interference, the control module is configured to provide an indication signal to the switching element;
• in response to the switching element receiving the indication signal, the switching element is configured to activate the vibration motor;
• in response to the vibration motor being activated, the vibration motor is configured to generate the indication;
• and
• the indication is a haptic alert.
