Definitions

  • the invention relates to a motor vehicle that is designed for autonomous driving, according to the preamble of claim 1, and to a method for producing a motor vehicle designed for autonomous driving.
  • the autonomous driving of a motor vehicle is understood in particular to mean that it can cover a certain distance without the driver having to intervene to control the motor vehicle.
  • the motor vehicles in question have powerful computers for controlling the motor vehicle during autonomous driving.
  • the need for such a powerful computer simply arises from the fact that - in order to ensure safe autonomous driving - the computer that controls the autonomously driving motor vehicle must evaluate a large number of data from a comparatively complex sensor system in the motor vehicle. This is necessary so that the computer is able to correctly record complex traffic situations with the highest level of reliability.
  • the decisions that have to be made by the computer to ensure safe autonomous driving are correspondingly complex and must be made in the shortest possible time.
  • the computer is difficult to access in this position, which makes maintenance work, which can be necessary on such a complex computer, more difficult. Furthermore, the computer is not as well protected in this position as one might assume due to the difficulty of accessing the computer. For example, spilled drinks in the back seat area pose a risk of possible damage to the computer.
  • the invention is therefore based on the object of demonstrating a motor vehicle designed for autonomous driving and a method for its production in which the disadvantages described above do not occur or at least occur to a reduced extent.
  • the motor vehicle is designed for autonomous driving.
  • a motor vehicle designed for autonomous driving is understood to mean, in particular, a motor vehicle that has the necessary sensors to enable an autonomous process, at least in some areas. This means in particular that the vehicle does not have to be able to handle any traffic situation autonomously.
  • a motor vehicle trained for autonomous driving is to be understood in particular as meaning a motor vehicle that can travel autonomously, for example following a route of a navigation system, and in particular can detect and independently handle complex traffic situations, and not just a motor vehicle that is trained to do so is to enable only individual, discrete driving maneuvers, such as automated parking, autonomously.
  • the motor vehicle has a computer for controlling the vehicle during autonomous driving.
  • the computer can in particular be a liquid-cooled computer.
  • Liquid cooling has the advantage of being comparatively large To enable computing performance, as the resulting heat can be effectively dissipated using liquid cooling.
  • the object is achieved in particular in that the computer is attached to a support element arranged in the rear of the motor vehicle body and attached to the body of the motor vehicle. Attaching the computer to such a support element allows the arrangement of a powerful and therefore heavy computer in question in the rear of the motor vehicle.
  • the support element in particular enables a connection between the computer and the motor vehicle body.
  • the computer can be arranged in the rear of the vehicle in such a way that, even in the event of a frontal collision of the motor vehicle, it is held sufficiently securely by the motor vehicle body and does not break loose and thus become a threat to the occupants of the motor vehicle. Otherwise, if the computer is arranged in the rear of the motor vehicle body, these could be hit from behind by the computer flying around and be seriously injured.
  • the arrangement of the computer in the rear of the motor vehicle body is advantageous. There the computer is not exposed to the influences that come from the people in the motor vehicle as described above.
  • the computer in the rear of the motor vehicle is easily accessible, for example for maintenance purposes.
  • the arrangement in the rear can in particular mean the arrangement in a spatial area within the motor vehicle body, which is the case with conventional, i.e. H. Motor vehicles that do not drive autonomously are typically used as trunks.
  • Such an arrangement of the computer enables, in particular, the greatest possible use of conventional motor vehicle bodies, for which the support element creates a suitable installation option for the computer.
  • the support element can be arranged in particular in the manner of a rack in the rear of the motor vehicle body.
  • the computer can be arranged behind a last row of seats of the motor vehicle as seen from the front of the vehicle. In most motor vehicle bodies there is a suitable space behind the last row of seats in a motor vehicle that can be used for arranging the computer. By attaching the computer using the support element and the resulting anchoring in the motor vehicle body, this also becomes safe with regard to frontal accidents.
  • the computer can be arranged in particular behind a rear seat back of the last row of seats of the motor vehicle. As a result, the computer is particularly at a height at which it On the one hand, it is largely safe from escaping liquids that come from the passenger area of the motor vehicle, and on the other hand, it is arranged at a height that is easily accessible for maintenance work.
  • the computer can be arranged behind a partition that separates the computer from a cargo hold that is arranged in front of the computer in the direction of travel.
  • the vehicle can in particular be a commercial vehicle, for example a transporter.
  • the computer in the rear of the motor vehicle body can be effectively protected from interference from the direction of the loading space; in this case, the loading space can be accessible in particular through one or more doors arranged on the side of the motor vehicle.
  • the support element can, at least essentially, be designed to be flat. Thanks to a flat design, such a support element offers a useful mounting position, not only for the computer, but also for other pieces of equipment of the motor vehicle that may be associated with the computer or the functionality for autonomous driving.
  • the support element can extend in particular in a horizontal plane in the rear. A horizontal extension of the support element advantageously enables the equipment in question to be arranged on it.
  • the computer can be attached to the support element by at least one connecting element attached to the computer.
  • the at least one connecting element can extend upwards along the computer away from the support element.
  • Such connecting elements enable a firm connection between the computer and the support element, since surface sides of the computer that do not face the support element can be used for fastening.
  • the connecting elements extend in particular along the surface of the computer and away from the support element upwards. Due to such a flat extension, the connecting elements offer good options for connecting to the computer and at the same time only minimally increase its space requirement on the support element, so that a corresponding amount of space is available for arranging further equipment next to the computer.
  • a plurality of connecting elements can be present in order to further increase the stability of the attachment of the computer to the support element.
  • the computer can be attached to a crossbar.
  • the crossbar is in particular spaced from the support element.
  • the crossbar can be arranged above the support element.
  • the crossbar offers an effective additional fastening option in order to securely fix the computer, especially in the event of a frontal collision of the motor vehicle.
  • the arrangement above and at a distance from the support element has a positive effect on the resulting mechanical stress on the components involved in the event of a frontal impact.
  • the crossbar can extend in particular in the transverse direction of the vehicle.
  • the crossbar can be attached to the motor vehicle body.
  • the attachment of a motor vehicle body can provide a secure anchoring of the crossbar, in which it can also absorb relatively large forces in the event of a frontal impact and pass them on to the motor vehicle body.
  • the extension of the crossbar transversely to the direction of travel makes it possible in particular to use the crossbar to span an area of the body that is located between two suitable fastening points for the crossbar, but does not itself provide suitable fastening options.
  • This spanned area can, for example, be an opening in the motor vehicle body, such as an opening that can be closed by a tailgate and/or a tailgate. In this way, the crossbar can be used to provide a useful additional fastening for the computer.
  • the crossbar is in particular spaced from the support element in the vertical direction of the vehicle by at least half of the height of the computer, in particular by 75% of the height of the computer.
  • the computer can be attached to the crossbar in particular by the at least one connecting element.
  • the connecting elements can be used advantageously to also attach the computer to the crossbar.
  • the connecting elements also create a mechanical connection between the support element and the crossbar, which contributes to additional stabilization of the overall construction.
  • the crossbar can advantageously provide further attachment points for further equipment arranged on the support element.
  • a coolant tank for a coolant for cooling the computer a cleaning liquid tank for a Cleaning liquid for cleaning sensors of the motor vehicle and / or a battery for supplying the computer and / or other components of the vehicle electronics with electrical energy.
  • Motor vehicles designed for autonomous driving require a large amount of cleaning fluid so that the sensors can be kept free of contamination.
  • This can expediently be kept in a tank which is arranged on the support element.
  • the tank for the cleaning liquid can have a capacity of at least 10 liters, preferably at least 15 liters.
  • the high-performance computers used can benefit from cooling using a coolant.
  • the coolant also has a considerable weight, so that the arrangement of a coolant tank for liquid cooling of the computer on the support element and in particular its attachment to the same is also advantageous.
  • motor vehicles of the type in question often require additional batteries to power the computer and/or other components of the vehicle electronics. This is particularly the case when it comes to an electrically powered vehicle. Batteries of the type in question also have a not inconsiderable weight, which is why attaching them to the support element is also advantageous.
  • the support element can be attached to the body in such a way that mass can be dissipated via the support element to the motor vehicle body.
  • the body In motor vehicles it is common practice to use the body as a ground pole.
  • a suitable attachment of the support element to the body which in particular brings about electrical contact between the body and the support element, in conjunction with a conductive material of the support element, can enable its use as a ground pole for the equipment of the motor vehicle arranged on the support element.
  • the support element can in particular use suitable contacting elements, such as WHT bolts, via the electrical and/or electronic equipment can be electrically connected to the support element.
  • the support element, the at least one connecting element and/or the crossbar can in particular be made of metallic materials.
