SUMMARY

A method for operating a driver assistance system of a motor vehicle is provided. The driver assistance system is configured as a parking aid system. In an embodiment, a determining takes place of a parameter characterizing an impending parking procedure of the motor vehicle in the longitudinal direction of the vehicle. In addition, a determining takes place of a first distance d1 of a lateral face of the motor vehicle on the driver's side to a parking space periphery on the driver's side. In addition, a determining takes place of a second distance d2 of a lateral face of the motor vehicle on the passenger's side to a parking space periphery on the passenger's side. Furthermore, an issuing of information takes place for a centered parking of the motor vehicle relative to the parking space periphery on the driver's side and to the parking space periphery on the passenger's side, based on the determined first distance d1 and the determined second distance d2 by an issuing device.

The method according to an embodiment enables a further improved parking aid. This takes place by the determining of the first distance d1 and of the second distance d2 and the issuing of information for a centered parking of the motor vehicle. Thereby, information is provided to the driver of the motor vehicle, by means of which the motor vehicle can be parked in a centered manner, i.e. can be parked such that the first distance d1 corresponds substantially to the second distance d2. Thereby, the motor vehicle has as equal as possible a distance to the parking space peripheries on the driver's and passenger's sides, whereby the likelihood of damage to the motor vehicle during and after the parking procedure can be reduced. The method therefore enables in particular a safe and easier parking of the motor vehicle in a car-wash or in a garage or respectively parking space. Furthermore, the method is advantageous for parking procedures in parking garages. Moreover, the method enables a greater comfort for the driver of the motor vehicle during parking procedures.

In an embodiment, the information contains the determined first distance d1 and the determined second distance d2. In this embodiment, the driver of the motor vehicle is therefore provided with the determined distances, whereby he can park the motor vehicle in a simple manner with as equal a lateral distance as possible. In addition, the information can contain the position of the motor vehicle together with the respective distances d1 and d2. Furthermore, the information can contain instructions for turning a steering wheel of the motor vehicle for a centered parking of the motor vehicle.

The issuing device can be configured as an acoustic and/or visual issuing device. For example, the issuing device can be a component of an instrument cluster of the motor vehicle or of an information and entertainment system of the motor vehicle.

In another embodiment, a method for operating a driver assistance system of a motor vehicle is provided wherein the driver assistance system is configured as a parking aid. The method has the following steps here. A determining takes place of a parameter characterizing an impending parking procedure of the motor vehicle in the longitudinal direction of the vehicle. In addition, a determining takes place of a first distance d1 of a lateral face of the motor vehicle on the driver's side to a parking space periphery on the driver's side. Furthermore, a determining takes place of a second distance d2 of a lateral face of the motor vehicle on the passenger's side to a parking space periphery on the passenger's side. Furthermore, an automatic actuation of a steering device of the motor vehicle takes place based on the determined first distance d1 and the determined second distance d2, such that the motor vehicle is parked in a centered manner to the parking space periphery on the driver's side and to the parking spacing periphery on the passenger's side.

The method according to this embodiment also enables a further improved parking aid, wherein in this arrangement a centered parking of the motor vehicle takes place by the automatic actuation of the steering device.

The sensor of the motor vehicle can be configured in particular as a parking sensor and/or as a sensor for blind spot monitoring. The sensors can therefore be used for the method and thereby the number of additionally required components for the method can again be reduced.

The parameter characterizing an impending parking procedure of the motor vehicle in the longitudinal direction of the vehicle can be an engaging of a reverse gear, in particular of a gear transmission of the motor vehicle. Furthermore, the parameter can be a falling below of a predetermined speed of the motor vehicle. The parameters are particularly suited here to determine such an impending parking procedure of the motor vehicle in the longitudinal direction of the vehicle.

Furthermore, the parameter can be an actuation of an activating device of the driver assistance system by an occupant of the motor vehicle, in particular by the driver of the motor vehicle. Thereby, he can automatically activate the parking aid function on driving into the parking space.

DETAILED DESCRIPTION

The following detailed description is merely exemplary in nature and is not intended to limit the various embodiments or the application and uses thereof. Furthermore, there is no intention to be bound by any theory presented in the preceding background or summary or the following detailed description.

FIG. 1 shows a flow diagram of a method for operating a driver assistance system of a motor vehicle according to an embodiment. The driver assistance system is configured here as a parking aid system. The motor vehicle is, for example, an automobile or a truck.

In a step 40 a determining takes place of a parameter characterizing an impending parking procedure of the motor vehicle in the longitudinal direction of the vehicle. The parameter can be the engaging of a reverse gear of a gear transmission of the motor vehicle. Furthermore, the parameter can be a falling below of a predetermined speed of the motor vehicle. In a further arrangement, the parameter is an actuation of an activating device of the driver assistance system by an occupant of the motor vehicle, for example, by the driver of the motor vehicle.

In a step 50 in the embodiment which is shown a determining takes place of a first distance d1 of a lateral face of the motor vehicle on the driver's side to a parking space periphery on the driver's side. In addition, in the step 50 a determining takes place of a second distance d2 of a lateral face of the motor vehicle on the passenger's side to a parking space periphery on the passenger's side. The lateral face on the driver's side can be formed here by a side wall of the motor vehicle on the driver's side. Accordingly, the lateral face on the passenger's side can be formed by a side wall of the motor vehicle on the passenger's side. The corresponding peripheries here can be, for example, walls of a garage or of a car wash. Furthermore, the peripheries can also be formed by lateral faces of other motor vehicles.

In an embodiment, the determining of the first distance d1 and of the second distance d2 takes place at the same time by data of a first sensor and of a second sensor of the motor vehicle. The first and/or the second sensor is, for example, chosen from an electromagnetic sensor, in particular a radar or lidar sensor, and an acoustic sensor, in particular an ultrasonic sensor. The first and/or the second sensor can additionally be configured as a parking sensor and/or as a sensor for blind spot monitoring. However, it is also possible that the first and/or the second sensor is provided in addition to a parking sensor or a sensor for blind spot monitoring.

In a step 60 in the embodiment which is shown, an issuing of information takes place for a centered parking of the motor vehicle relative to the parking space periphery on the driver's side and to the parking space periphery on the passenger's side based on the determined first distance d1 and on the determined second distance d2 by an issuing device of the motor vehicle. The information, in an embodiment, contains the determined first distance d1 and the determined second distance d2 and further the position of the motor vehicle relative to the parking space peripheries. Furthermore, it is possible that the information contains instructions for turning a steering wheel of the motor vehicle for a centered parking of the motor vehicle. The issuing device is configured, for example, as an acoustic and/or visual issuing device and can be a component of an instrument cluster or of an information and entertainment system of the motor vehicle.

The steps 50 and 60 are carried out repeatedly, i.e. the determining of the first distance d1 and the determining of the second distance d2 and the issuing of the information take place repeatedly, until the parking procedure of the motor vehicle is completed and it is parked as centered as possible to the parking space periphery on the driver's side and on the passenger's side.

FIG. 2 shows a flow diagram of a method for operating a driver assistance system of a motor vehicle according to another embodiment. The driver assistance system is again configured as a parking aid system and the motor vehicle is, for example, an automobile or a truck.

In the embodiment which is shown, in a step 40 a determining takes place of a parameter characterizing an impending parking procedure of the motor vehicle in the longitudinal direction of the vehicle in accordance with the step 40 of the embodiment shown in FIG. 1.

Furthermore, in a step 50 a determining takes place of a first distance d1 of a lateral face of the motor vehicle on the driver's side to a parking space periphery on the driver's side and of a second distance d2 of a lateral face of the motor vehicle on the passenger's side to a parking space periphery on the passenger's side in accordance with the step 50 of the first embodiment shown in FIG. 1.

In addition, in the embodiment which is shown, in a step 60′ an automatic actuating of a steering device of the motor vehicle takes place based on the determined first distance d1 and the determined second distance d2, such that the motor vehicle is parked centered to the parking spacing periphery on the driver's side and to the parking space periphery on the passenger's side.

The steps 50 and 60′ are again carried out repeatedly in order to enable a substantially centered parking of the motor vehicle.

In the embodiments which are shown, therefore for example by the lateral parking sensors, which are used for measuring a parking space, the driver of the motor vehicle or respectively the motor vehicle is directed with as equal as possible lateral distance for example into a car wash entrance or garage entrance, so that the vehicle can be parked in a centered manner. On driving into the garage or into the car wash, the center of the vehicle or respectively the lateral distances of the motor vehicle to the corresponding parking space peripheries is determined by the lateral parking sensors for measuring a parking space. The position and the distance to the respective lateral faces or respectively side walls can be indicated to the driver in a vehicle display. In the embodiment shown in FIG. 2, the function is coupled with a fully automatic parking function in the form of an electronic steering wheel intervention. When driving into a garage or into a car wash, the driver can therefore activate the function for example by a switch, and the corresponding driver assistance system of the motor vehicle determines automatically the center of the entrance or respectively steers the vehicle automatically into the center. The parking sensors are included here so that the vehicle does not cause any contact with the wall.

The methods according to the embodiments enable a benefit to the customer through a greater comfort and provide a new function. Furthermore, a safe and easier parking of the motor vehicle is enabled for example in a car wash or in a garage or respectively parking space.

FIGS. 3A and 3B show an example of a parking procedure in which the methods according to the embodiments can be used, in particular the methods according to the embodiments shown in FIGS. 1 and 2. Components with the same functions are designated here by the same reference numbers.

In the situation illustrated in FIG. 3A, a motor vehicle 2, which in the example shown is an automobile, travels in a travel direction represented diagrammatically by an arrow A. The travel direction corresponds substantially to a vehicle longitudinal direction of the motor vehicle 2.

The motor vehicle 2 is situated at the start of a parking procedure in the longitudinal direction of the vehicle, i.e. in the travel direction of the motor vehicle 2, into a parking space arranged in the longitudinal direction of the vehicle, of which a parking space periphery 4 on the driver's side and a parking space periphery 6 on the passenger's side are illustrated. The corresponding peripheries can be, for example, walls of a garage or of a car wash. Furthermore, the peripheries can also be formed by lateral faces of further motor vehicles, for example in a parking garage.

In the embodiment which is shown, the motor vehicle 2 has sensors 9 and 9′ on the driver's side and sensors 10, 10′ on the passenger's side. The sensors 9 and 10 are situated here in the region of a front bumper and the sensors 9′ and 10′ in the region of a rear bumper of the motor vehicle 2. The sensors 9, 9′, 10 and 10′ are configured for example as electromagnetic sensors, in particular as radar or as lidar sensors, or as acoustic sensors, in particular as ultrasonic sensors. Furthermore, the sensors can be configured as a parking sensor of the motor vehicle.

The sensors 9 and 9′ have diagrammatically illustrated detection ranges 18 or respectively 18′, which extend respectively into a region of the lateral environment of the motor vehicle 2 on the driver's side. The sensors 10 and 10′ have detection ranges 19 or respectively 19′, which extend respectively into a region of the lateral environment of the motor vehicle 2 on the passenger's side.

In the situation shown in FIG. 3A, the parking space periphery 4 on the driver's side is situated at least partially within the detection range 18 of the sensor 9, and the parking space periphery 6 on the passenger's side is situated at least partially within the detection range 19 of the sensor 10. Thereby, by data of the sensor 9, a first distance d1 can be determined of a lateral face 3 of the motor vehicle 2 on the driver's side to the parking space periphery 4 on the driver's side, and by data of the sensor 10, a second distance d2 can be determined of a lateral face 5 of the motor vehicle 2 on the passenger's side to the parking space periphery 6 on the passenger's side.

In the situation shown in FIG. 3A at the start of the parking procedure, the first distance d1 is greater than the second distance d2. As will be explained in further detail in connection with the following figures, a centered parking of the motor vehicle 2 can be enabled by a driver assistance system configured as a parking aid system.

FIG. 3B shows the motor vehicle 2 at the end of the parking procedure, wherein by the corresponding driver assistance system a centered parking has taken place, i.e. the first distance d1 of the lateral face 3 on the driver's side to the parking space periphery 4 on the driver's side corresponds substantially to the second distance d2 of the lateral face 5 on the passenger's side to the parking space periphery 6 on the passenger's side.

In the situation which is shown, by the sensors 9 and 10 the first distance d1 or respectively the second distance d2 is determined at a front end of the motor vehicle 2. In addition, by the sensors 9′ and 10′ a distance d1′ of the lateral face 3 on the driver's side to the parking space periphery 4 on the driver's side or respectively a distance d2′ of the lateral face 5 on the passenger's side to the parking space periphery 6 on the passenger's side is determined at a rear end of the motor vehicle 2. The first distance d1 corresponds in the situation shown substantially to the distance d1′ and the latter in turn substantially to the distance d2′. The motor vehicle 2 is therefore parked in a centered manner in the parking space both in the front region and also in the rear region.

FIG. 4 shows a driver assistance system 1 of the motor vehicle shown in FIGS. 3A and 3B according to an embodiment. Components with the same functions as in FIGS. 3A and 3B are designated by the same reference numbers and are not explained again in the following.
