Abstract
A method for monitoring a vehicle (1) having a vehicle superstructure (2), a chassis (3) connected to the vehicle superstructure (2), and a monitoring unit (11) which monitors the chassis (3) for damage. In the event that chassis damage is detected, the monitoring unit produces a warning signal (S) by means of a warning signal generator, where the warning signal generator has at least one drive unit (10) by means of which the warning signal (S) is produced in the form of a tactile mechanical vibration.
Claims13
A method for monitoring a vehicle which comprises a vehicle superstructure, a chassis connected to the vehicle superstructure and a monitoring unit which monitors the chassis for damage, the method comprising:
- detecting chassis damage with the monitoring unit based on vibrations detected in the chassis by sensors arranged in at least one of the chassis and the vehicle superstructure;
- comparing, with the monitoring unit, the vibrations detected in the chassis to different characteristic vibration patterns that are stored in the monitoring unit, the stored different characteristic vibration patterns correspond to different types of chassis damage;
- identifying, with the monitoring unit, the type of chassis damage by associating the vibrations detected in the chassis to one of the different characteristic vibration patterns and an associated type of chassis damage;
- producing a warning signal that corresponds to the type of chassis damage identified with the monitoring unit, the warning signal being produced with a warning signal generator which has at least one drive unit, the at least one drive unit being actuatable to produce the warning signal which is formed as a tactile mechanical vibration;
- and
- communicating the warning signal to an operator of the vehicle by transmitting the warning signal from the warning signal generator into the chassis and/or the vehicle superstructure such that the chassis and/or the vehicle superstructure mechanically vibrates.

- and
- transmitting the warning signal from the warning signal generator into the chassis and/or the vehicle superstructure such that the chassis and/or the vehicle superstructure mechanically vibrates;
- and
- wherein the vehicle comprises a vehicle drive unit which forms the warning signal generator, and at least one vehicle motor that forms the at least one drive unit, the method further including controlling the at least one vehicle drive motor as a function of the warning signal to produce intermittent and/or periodic accelerations of the vehicle.
