Safety device for motor vehicle and method for operating a motor vehicle
First Claim
1. A safety device for a motor vehicle (1) with at least one sensor unit (2) for detecting the environmental conditions and for the output of environmental data, an evaluation unit (4) for merging the environmental data and an evaluation unit (5) for detecting free spaces and objects (O), and the position and movement thereof, and with at least one sensor unit (20) for detecting the state of the environment and for the output of environmental status data and an evaluation unit (24) for merging the environmental data with the environmental status data to determine a proposed coefficient of friction, and with at least one sensor unit (30) for detecting the vehicle state and for the output of vehicle status data and an evaluation unit (34) for merging the vehicle status data with the proposed coefficient of friction and the driver input data to determine the driving state, and with at least one sensor unit (40) for detecting the driver inputs and for the output of driver input data and an evaluation unit (44) for merging the driver input data with the vehicle status data to determine the driver'"'"'s setpoint course, characterized in that a driving safety coordinator (6) predictively and situatively determines at least one permissible driving corridor (K1, K2, K3, K4 to Kn) in order to ensure operational safety and restricts the driver input to the driving corridor using actively addressable components (9) and keeps the motor vehicle (1) in the driving corridor (K1, K2, K3, K4 to Kn) using the actively addressable components (9).

Abstract
The application relates to a device and a method for increasing the safety of a motor vehicle. A first sensor unit (2) senses the surroundings, in particular in order to detect free spaces and objects (0), and the position and movement thereof. A second sensor unit (20) senses the state of the surroundings, a third sensor unit (30) senses the state of the vehicle, and a fourth sensor unit (40) senses the driver'"'"'s commands. The data are merged and a driving safety coordinator (6) determines at least one reliable driving corridor (K1, K2, K3, K4 to Kn) predictively and situationally in order to determine the operational safety. The driver'"'"'s command can be limited to the driving corridor (K1, K2, K3, K4 to Kn) by means of components (9) which can be actuated actively and/or the motor vehicle (1) can be kept in the driving corridor (K1, K2, K3, K4 to Kn) by means of the components (9) which can be actuated actively.
