Method and brake system for actuating a brake actuator in order to reduce tensioning of a vehicle

A brake system including an electronically controllable pneumatic brake system for a vehicle for actuating a brake actuator in a braked, stationary vehicle, the brake system comprising:

• a sensor unit for monitoring a state variable (Z1, Z2, Z3) defining a state of loading of the vehicle;
• a displacement sensor for detecting a stress in the vehicle produced by a level change;
• and,
• a control device having a signal connection to said sensor unit and to said displacement sensor;
• said control device being configured to release the brake actuator in a response to the detection of a stress and wherein at least one of the following applies:
• i) for the case wherein the state variable (Z1, Z2, Z3) can be assigned to the predefined value range to actuate a first target braking level;
• and,
• ii) for the case wherein the state variable (Z1, Z2, Z3) cannot be assigned to the predefined value range to actuate a second target braking level.

A vehicle including a commercial vehicle, the vehicle comprising:

• an axle suspended on trailing arms or semi-trailing arms;
• and,
• a brake system for actuating a brake actuator in a braked, stationary vehicle;
• said brake system including:
• a sensor unit for monitoring a state variable (Z1, Z2, Z3) defining a state of loading of the vehicle;
• a displacement sensor for detecting a stress in the vehicle produced by a level change;
• and,
• a control device having a signal connection to said sensor unit and to said displacement sensor;
• said control device being configured to release the brake actuator in a response to the detection of a stress and wherein at least one of the following applies:
• i) for the case wherein the state variable (Z1, Z2, Z3) can be assigned to the predefined value range to actuate a first target braking level;
• and,
• ii) for the case wherein the state variable (Z1, Z2, Z3) cannot be assigned to the predefined value range to actuate a second target braking level.
