Method for controlling a locking system of a motor vehicle and a motor vehicle
First Claim
1. A method for controlling a locking system of a motor vehicle, said locking system having an unlocked state, a locked state and a safe state, wherein a switchover from the locked state into the unlocked state is enabled by operating a first control element, whereas a switchover from the safe state into the unlocked state is prevented when only the first control element is operated, the method comprising the steps of:
- with an alarm system being deactivated by a user, allowing the locking system to switch only into the locked state, andwith the locking system being switched by the user from the unlocked state into the safe state,automatically determining for a predetermined time interval a first signal indicating a presence or absence of a person inside the motor vehicle and switching the locking system into the unlocked state or the locked state, if the first signal indicates the presence of a person inside the motor vehicle,outputting a warning message indicating that the locking system will be transitioning from the locked state into the safe state, unless a second control element is activated within a predetermined time interval, whereas the locking system remains in the locked state if the second control element is activated, andwith the locking system being in the safe state, when a second signal indicating that a person inside the motor vehicle wishes to exit the motor vehicle is detected, automatically determining a first signal indicating the presence or absence of a person inside the motor vehicle and if the first signal indicates that a person is present inside the motor vehicle, switching the locking system into the unlocked state or the locked state, or outputting inside the motor vehicle an instruction for action via optical and/or acoustical output means, and switching the locking system into the unlocked state or the locked state after the instruction for action is executed within a predetermined time.

Abstract
The invention relates to a method for controlling a locking system of a motor vehicle wherein, as the states of the locking system, there is an unlocked state, a locked state from which it is possible to switch to the unlocked state via at least a first operating element inside the vehicle, and a security state in which by simply activating a first operating element it is not possible to switch to the unlocked state. The aim of the invention is to propose a method that allows a person inside the motor vehicle to still leave the motor vehicle despite user activation of the security state without substantially easing the opening of the motor vehicle from the outside by an unauthorized third party. Four concepts are proposed that can all be implemented in combination to great benefit. They enable a person still inside the vehicle to leave the motor vehicle upon activation of the security state.

20. A motor vehicle comprising a locking system having an unlocked state, a locked state and a safe state, wherein a switchover from the locked state into the unlocked state is enabled by operating a first control element located inside the motor vehicle, whereas a switchover from the safe state into the unlocked state is prevented when only the first control element is operated, wherein the locking system is configured to:
-
with an alarm system being deactivated by a user, switch exclusively into the locked state, and with the locking system being switched by the user from the unlocked state into the safe state, automatically determine for a predetermined time interval a first signal indicating a presence or absence of a person inside the motor vehicle and switch the locking system into the unlocked state or the locked state, if the first signal indicates the presence of a person inside the motor vehicle, or output a warning message indicating that the locking system will be transitioning from the locked state into the safe state, unless a second control element is activated within a predetermined time interval, whereas the locking system remains in the locked state if the second control element is activated, and with the locking system being in the safe state, when a second signal indicating that a person inside the motor vehicle wishes to exit the motor vehicle is detected, automatically determine a first signal indicating the presence or absence of a person inside the motor vehicle and if the first signal indicates that a person is present inside the motor vehicle, switch the locking system into the unlocked state or the locked state, or output inside the motor vehicle an instruction for action via optical and/or acoustical output means, and switch the locking system into the unlocked state or the locked state after the instruction for action is executed within a predetermined time.
