Abstract

A driver information system for a motor vehicle having an operator control for operating the driver information system, a device for detecting travel of the motor vehicle, and a control for limiting and/or preventing an operation of the driver information system via the operator control in the case that motor vehicle travel is recognized, in which a device for detecting the occupancy of a passenger seat of the vehicle is provided, and the control is designed to at least partially cancel the limitation and/or prevent the operation of the driver information system. A driver information system advantageously makes use of a signal that is available in many vehicles and indicates the occupancy of a passenger seat, in order to influence a speed-lock function of the driver information system and, thus, also during vehicle travel, to render possible an operation of the driver information system to a full extent or to an extent that is at least expanded as compared to the speed-lock function. At the same time, the advantages of the speed-lock function, namely that the driver is distracted to a lesser degree by the operation of the vehicle information system, are retained, so that the result is better concentration on the actual driving task and, ultimately, improved traffic safety.

Claims

1. A driver information system for a motor vehicle, comprising:

an operator control for operating a driver information system;

a first device for detecting travel of the vehicle;

a second device for detecting an occupancy of a passenger seat of the vehicle; and

a control for at least one of limiting and preventing an operation of the driver information system via the operator control in the case that vehicle travel is recognized, the control being adapted to at least one of at least partially cancel the limitation and prevent the operation of the driver information system.

2. The driver information system according to claim 1, wherein a seat belt for a safety belt assigned to the passenger seat emits a signal indicating the occupancy of the passenger seat.

3. The driver information system according to claim 1, wherein the passenger seat has a sensor for emitting a signal indicating the occupancy of the passenger seat.

4. The driver information system according to claim 3, wherein the sensor is a weight sensor.

5. The driver information system according to claim 1, wherein at least one of the partial cancellation of the limitation and prevention of the operation of the driver information system includes tasks that are limited compared to standstill of the vehicle via an output device of the driver information system.
