Problems solved by technology

In addition, from a safety point of view, even if the control unit has started the brake operation, there may be a situation where the vehicle rolls for a certain period of time
[0004]In addition to the loss of comfort, there are additional disadvantages associated with this: as mentioned above, the instantaneous speed of the vehicle is very important for the brake operation and the requested brake torque plays a very important role
If the vehicle accelerates due to external influences such as gusts of wind or due to the slope of the parking space, the timing of such acceleration and braking processes may be intensified

Embodiment Construction

[0044] figure 1 A schematic top view of a vehicle 10 that can be operated with the proposed method is shown. The vehicle 10 has an engine 12 , in this application an internal combustion engine, which can also be realized as an electric motor. The engine 12 provides an engine torque via an engine output shaft 14 which is transferred to a torque converter 16 . The torque converter 16 is connected to a driveline 18 with which the drive torque MA provided by the torque converter 16 can be distributed to a plurality of wheels 20 . In the example shown, the vehicle 10 has four wheels 20 , with the front wheels driven via a driveline 18 . For this purpose, the drive train 18 has a suitable differential 22 . The drive torque MA transferred from the torque converter 16 to the driveline 18 may be registered by means of a torque sensor 24 . However, since the characteristics of the engine 12 and torque converter 16 are generally known such that the drive torque MA transmitted from th...

Abstract

The invention relates to a method for decelerating a vehicle (10) moving at low speed (vV), in particular by using a hydraulically or pneumatically operated braking system (26), with the following steps: determining, by means of the speed sensor (32), whether the speed (vV) of the vehicle (10) falls short of a predeterminable first limiting value (vC1); if the speed (vV) of the vehicle (10) fallsshort of the first limiting value, increasing the propulsion torque (MA) transmitted to the drive train (18); and decelerating the vehicle (10) by increasing the braking torque (MB) acting on the wheels (20) by means of the controller (36).

Description

technical field [0001] The invention relates to a method of decelerating a vehicle moving at low speed, in particular by using a hydraulically or pneumatically operated braking system. Furthermore, the invention relates to a computer program product capable of carrying out the method, and also to a vehicle having a computer program product of this type. Background technique [0002] Modern vehicles have braking systems that operate autonomously or partially autonomously to slow the vehicle and regulate the speed of the vehicle. An autonomously operated braking system is suitable for autonomously driven vehicles in which the driver has no possibility—or at most very limited possibility—to influence the driving maneuver performed by the vehicle. In certain driving situations, a partially autonomously operating braking system can initiate a braking maneuver without the driver having to become active for this purpose even if he / she is seated at the controls. An example of such...
