Abstract
A method for determining a maximum speed for a vehicle, including: receiving items of state information concerning a state of at least one vehicle component of the vehicle; and determining a maximum speed of the vehicle on the basis of the state information, such that a stopping path of the vehicle from a recognition of a dangerous state until the vehicle is at a standstill is less than or equal to a specified value.
Claims9
A method of a vehicle, the method comprising:
- the vehicle monitoring a state of a braking system of the vehicle;
- a processor of the vehicle determining, as a first time period and based on the monitored state of the braking system, an amount of time required for building up a maximum braking potential in the braking system;
- the processor determining, as a second time period, an amount of time required to bring the vehicle to a standstill after the maximum braking potential is built up in the braking system;
- the processor determining a maximum speed of the vehicle based on the first and second time periods, such that a stopping path of the vehicle from a recognition of a dangerous state until the vehicle is at a standstill is less than or equal to a specified value;
- and
- the processor outputting an indication of the determined maximum speed to a user interface or performing an automatic control of the vehicle speed based on the determined maximum speed.

A device of a vehicle, the device comprising:
- a processor;
- and
- an input interface;
- wherein the processor is configured to:
- receive state information about, and obtained by the vehicle monitoring, a state of a braking system of the vehicle;
- determine, as a first time period and based on the monitored state of the braking system, an amount of time required for building up a maximum braking potential in the braking system;
- determine, as a second time period, an amount of time required to bring the vehicle to a standstill after the maximum braking potential is built up in the braking system;
- determine the maximum speed of the vehicle based on the first and second time periods so that a stopping path of the vehicle from a recognition of a dangerous state until the vehicle is at a standstill is less than or equal to a specified value;
- and
- output an indication of the determined maximum speed to a user interface of the device or perform an automatic control of the vehicle speed based on the determined maximum speed.

An automated driving system for a vehicle, the automated driving system comprising:
- a device including a processor and an input interface, wherein the processor is configured to:
- receive state information about, and obtained by the vehicle monitoring, a state of a braking system of the vehicle;
- determine, as a first time period and based on the monitored state of the braking system, an amount of time required for building up a maximum braking potential in the braking system;
- determine, as a second time period, an amount of time required to bring the vehicle to a standstill after the maximum braking potential is built up in the braking system;
- determine the maximum speed of the vehicle based on the first and second time periods so that a stopping path of the vehicle from a recognition of a dangerous state until the vehicle is at a standstill is less than or equal to a specified value;
- perform an automatic control of the vehicle speed based on the determined maximum speed.
