Definitions
- the present invention relates to a method for operating a vehicle with a steer-by-wire steering device and an immobilizer.
- the invention also relates to a vehicle operated in this way.
- the vehicle To steer a vehicle, the vehicle usually has a steering sensor, in particular a steering wheel, which can be moved accordingly. At least one steerable wheel of the vehicle is moved depending on the steering movement of the steering sensor.
- An associated steering device is increasingly designed as a so-called steer-by-wire steering device, in which there is no immediate and direct connection between the steering sensor and at least one wheel.
- Vehicles usually have an immobilizer, which can be used to prevent the vehicle from being steered.
- a corresponding vehicle is known from DE 10046 167 A1.
- the immobilizer is implemented by means of a mechanical locking of the steering device.
- a vehicle with a steer-by-wire steering system and an immobilizer is known from DE 10200969 354 A1.
- the intended use of the vehicle is prevented if, when the vehicle's ignition is switched on, it is determined that the immobilizer is in an unlocked state, i.e. the immobilizer is in a deactivated state.
- the present invention is concerned with the object of providing improved or at least different embodiments for a method for operating a vehicle of the type mentioned at the outset and for such a vehicle, which are characterized in particular by a reduced installation space requirement, reduced weight and reduced costs.
- This object is achieved according to the invention by the subject matter of the independent claims.
- Advantageous embodiments are the subject matter of the dependent claims.
- the present invention is therefore based on the basic idea of implementing the function of an immobilizer by means of electronic control by blocking the transmission of steering information from a steering sensor to a steering actuator and/or the control of a wheel by means of the steering actuator using software.
- mechanical components for implementing the immobilizer can be omitted, resulting in a more compact design and more cost-effective production of a steering device comprising the steering sensor and in particular the steering sensor.
- the more compact design of the steering sensor allows in particular the steering sensor to be designed to be movable, in particular foldable, so that it can be accommodated with reduced installation space requirements if necessary, in particular when the vehicle is driving autonomously.
- the vehicle has a steering axle and at least one wheel associated with the steering axle, as well as a data bus.
- the vehicle also has a steer-by-wire steering device, which is also referred to below as the steering device for short.
- the steering device comprises the steering sensor and a component connected to the steering sensor for detecting a steering movement of the steering sensor, which is also referred to below as the steering receiver component.
- the steering device comprises a steering actuator for controlling at least one wheel of the steering axle.
- the vehicle's immobilizer is communicatively connected to the data bus. The immobilizer can be switched between an active state and a deactive state, with the immobilizer locking the vehicle's steering in the active state and enabling it in the deactive state.
- the steering receiver component detects the steering movement of the steering sensor and transmits steering information dependent on the steering movement to the data bus.
- the steering actuator receives the steering information via the data bus and controls at least one wheel of the steering axle depending on the steering information. If the immobilizer is activated, i.e. it is in the active state, the transmission of the steering information to the data bus is blocked by software in the steering receiver component and/or the control of at least one wheel of the steering axle is blocked by software in the steering actuator.
- the software implementation of blocking the transmission of steering information to the data bus is implemented with a lock that is integrated in the steering slave component in software terms, which is also referred to below as the slave lock.
- the slave lock is therefore integrated in the steering slave component in software terms.
- the immobilizer communicates with the slave lock via the data bus. In the active state, the immobilizer activates the slave lock, i.e. via the data bus, so that the slave lock blocks the transmission of steering information to the data bus.
- Preferred embodiments are those in which the software implementation of the lock for controlling the at least one wheel of the steering axle in the steering actuator is implemented with a lock integrated in the steering actuator, which is also referred to below as a sensor lock.
- the sensor lock is therefore integrated in the steering actuator using software.
- the immobilizer communicates with the sensor lock via the data bus. The immobilizer activates the sensor lock in the active state, so that the sensor lock blocks the control of the at least one wheel of the steering axle.
- the cryptographic communication can be implemented, for example, using a challenge-response method based on a symmetric cipher, also known by the English term "symmetry cipher”, and/or using a "keyed-hash message authentication code”, also known by the abbreviation "HMAC”, and/or using a "block cipher-based message authentication code”, also known by the abbreviation "CMAC”.
- the cryptographic key used in each case is advantageously generated individually for the steering slave component, in particular for the slave lock, and for the steering actuator, in particular for the transmitter lock.
- the challenge is also generated by the steering slave component, in particular by the slave lock, and/or by the steering actuator, in particular by the transmitter lock, using a cryptographic random number generator.
- cryptographic communication can be implemented via an asymmetric signature procedure and/or by means of a procedure based on digital certificates.
- cryptographic communication can be implemented using a one-time password procedure.
- a device for access and driving authorization is provided for the vehicle.
- the device also referred to below as the access and driving authorization device, serves in particular the purpose of switching the immobilizer between the active state and the deactive state.
- the access and driving authorization device can also activate and deactivate a door lock of the vehicle and/or be used to start the vehicle.
- the access authorization device can be, for example, a vehicle key or comprise a vehicle key.
- the access authorization device can be or comprise an individually coded electronic device, for example a smartphone.
- the access authorization device can be implemented using a cryptographic code which is transmitted to the vehicle via a wireless data connection, i.e. in particular online.
- the immobilizer is in the active state when the vehicle is at rest and/or is switched to the active state.
- a vehicle operated in this way also belongs to the scope of this invention.
- the vehicle in particular the steering receiver component and/or the steering actuator, is designed accordingly.
- the steering sensor can be designed in any way.
- the steering sensor can be a steering wheel.
- the steering sensor is free of mechanical locks for implementing the immobilizer. As explained above, this leads to a compact design of the steering sensor and reduced manufacturing costs.
- the steering sensor is foldable.
- the steering sensor is foldable and free of mechanical locks. This means that the steering sensor can be compactly housed if required, particularly in an autonomous driving mode of the vehicle, and thus requires little or no installation space in the vehicle, particularly in the passenger compartment.
- the steering system and/or the immobilizer are completely free of mechanical locks.
- the steering device is free of mechanical locks between the steering sensor and the steering receiver component. This results in a more compact design and further reduced manufacturing costs.
- the steering device is preferably free of mechanical locks between the steering actuator and the at least one wheel of the steering axle.
- Fig. 1 is a highly simplified, schematic and circuit diagram-like representation of a vehicle.
- a vehicle 1, as shown in Figure 1 in a highly simplified and circuit-diagram-like manner, has a steering axle 2 and at least one wheel 3 associated with the steering axle 2.
- the vehicle 1 has, purely by way of example, two wheels 3 associated with the steering axle 2.
- the vehicle 1 has a data bus 4 for data transmission.
- the vehicle 1 has a link device 5 for steering the vehicle 1, which is designed as a steer-by-wire steering device 5.
- the steering device 5 has a steering sensor 6, which can be moved by a user, wherein such a movement of the steering sensor 5 is referred to below as a steering movement.
- the steering sensor 6 is designed purely by way of example as a steering wheel 7.
- the steering device 5 also has a component 8 for detecting the steering movement of the steering sensor 6, which is connected to the steering sensor 6 and is also referred to below as the steering receiver component 8.
- the steering receiver component 8 is able to transmit steering information dependent on the steering movement of the steering sensor 6 to the data bus 4.
- the steering device 5 also has an actuator 9 for controlling the at least one wheel 3 of the steering axle 2, which is also referred to below as steering actuator 9.
- the steering actuator 9 is thus able to control the at least one wheel 3 for steering the vehicle 1.
- the vehicle 1 also has an immobilizer 10.
- the immobilizer 10 can be activated and deactivated, i.e. can be switched between an active state and a deactive state.
- the steering receiver component 8 detects the steering movement of the steering sensor 6 and transmits steering information dependent on the steering movement to the data bus 4.
- the steering actuator 9 receives the steering information via the data bus 4 and controls at least one wheel 3 of the steering axle 2 depending on the steering information.
- the immobilizer 10 If the immobilizer 10 is activated, i.e. it is in the active state, steering of the vehicle 1 is prevented and thus blocked.
- the transmission of the steering information to the data bus 4 in the steering receiver component 8 is blocked by software and/or the control of at least one wheel 3 in the steering actuator 9 is blocked by software.
- both the transmission of the steering information to the data bus 4 in the steering receiver component 8 and the control of at least one wheel 3 in the steering actuator 9 are blocked by software.
- an associated lock 11 is integrated in the steering slave component 8 by software, which is also referred to below as slave lock 11.
- the immobilizer 10 communicates with the slave lock 11 via the data bus 4. In the active state, the immobilizer 10 activates the slave lock 11 so that the slave lock 11 blocks the transmission of the steering information to the data bus 4. In the deactive state of the immobilizer 10, the slave lock 11 is deactivated so that the steering information is transmitted to the data bus 4.
- An associated lock 12 is integrated in the steering actuator 9 in terms of software, which is also referred to below as the sensor lock 12.
- the immobilizer 10 communicates with the sensor lock 12 via the data bus 4. In the active state, the immobilizer 10 activates the sensor lock 12 so that the sensor lock 12 blocks the control of at least one wheel 3. In contrast, the sensor lock 12 is deactivated in the deactive state of the immobilizer 10 so that the steering actuator 9 controls at least one wheel 3 depending on the steering information.
- the steering device 5 is free of mechanical locks between the steering sensor 6 and the steering receiver component 8 and between the steering actuator 9 and the at least one wheel 3 of the steering axle 2.
- the steering sensor 6 is free of mechanical locks and is thus designed to be compact.
- the steering sensor 6 is also foldable.
- the steering sensor 6 can therefore be folded more easily, particularly due to the lack of a mechanical lock, and can be accommodated in a space-saving manner, for example when the vehicle 1 is driving autonomously.
- the communication between the immobilizer 10 and the slave lock 11 as well as the master lock 12 via the data bus 4 takes place cryptographically, for example by means of a challenge-response procedure and/or by means of an asymmetric signature procedure and/or by means of a procedure based on digital certificates and/or by means of a one-time password procedure.
- the activation and deactivation of the immobilizer 10, i.e. the switching of the immobilizer 10 between the active state and the deactive state takes place in the embodiment shown via a device 13 for access authorization to the vehicle 1, which is also referred to below as access authorization device 13.
- the access authorization device 13 can, for example, comprise a vehicle key (not shown).
- the immobilizer 10 is in the active state when the vehicle 1 is in a rest state or is switched to the active state.
