Tactile signaling
First Claim
Patent Images
1. A system for a motor vehicle comprising:
- at least one operator control unit of the motor vehicle having a functionality that is free of a fault condition; and
a monitoring unit monitors the fault-free functionality of the at least one operator control unit and generates signals to notify the operator of a need to service the control unit so that fault-free functionality is maintained;
the monitoring unit generates tactile signals when limit-value functions of the at least one operator control unit occur so the status of the at least one operator control unit can be communicated haptically to a driver of the motor vehicle, the tactile signal is generated with a time offset such that the driver does not become aware of the haptic communication until the motor vehicle is in a non-critical driving situation as determined by an electronic stability program, the tactile signal is communicated continuously after the motor vehicle has reached the non-critical driving situation until a time in which the monitoring unit is reset.

Abstract
The invention relates to a system for a motor vehicle having a monitoring unit which monitors a fault-free functionality of at least one operator control unit of the motor vehicle and generates warning signals in the case of limit-value functions of the at least one operator control unit. The monitoring unit generates tactile signals as warning signals so that degradation of performance of the at least one operator control unit can be communicated haptically to a driver of the motor vehicle.
