1. An emergency braking system of a single-track vehicle, which intervenes in a brake of the single-track vehicle, comprising:
a plurality of sensors, each sensor of the plurality of sensors being configured to detect at least one of a plurality of physical variables;
at least one sensor evaluation unit connected to at least one sensor of the plurality of sensors; and
an emergency braking system control unit connected to the at least one sensor evaluation unit, wherein the plurality of sensors includes one or both of a driver bracing sensor and a pillion bracing sensor,
the at least one sensor of the plurality of sensors connected to the at least one sensor evaluation unit is configured to send a sensor signal associated with at least one of the plurality of the physical variables to the at least one sensor evaluation unit, the sensor signal including a signal indicative of a level of bracing of one or both of the driver and a passenger on the pillion generated by one or both of the driver sensor and the pillion bracing sensor,
the at least one sensor evaluation unit is configured to determine from the sensor signal at least one risk value and to send the at least one risk value to the emergency braking system control unit,
the emergency braking system control unit is configured to
weight the at least one risk value, and
determine an accident risk actual value using the at least one risk value resulting from the weight determined by the emergency braking system control unit,
compare the accident risk actual value with an accident risk target value,
determine from sensor signals from the plurality of sensors, including the sensor signal from the at least one sensor, a road distance in which the single-track vehicle is to be stopped and a target braking force characteristic to obtain a vehicle deceleration that results is stopping of the single-track vehicle within the road distance, the vehicle deceleration being no greater than a deceleration above which one or both of the driver and the passenger on the pillion would become unseated from the single-track vehicle while the brake is decelerating the vehicle determined from the level of bracing, and
when the accident risk actual value exceeds the accident risk target value, to initiate actuation of the brake, and
after initiation of actuation of the brake by the emergency braking system control unit, control a braking force of the brake to control an actual braking force characteristic to the target braking force characteristic.
