US Patent 10173681 Method and device for automatically regulating vehicle longitudinal dynamics

Automatically regulating vehicle longitudinal dynamics in accordance with a preceding vehicle includes determining a first state variable dependent on vehicle acceleration, a second state variable dependent on engine drive torque, a third state variable dependent on the operating state of at least one permanent brake, and information about the preceding vehicle, and adjusting at least one regulating parameter of a regulation function and regulating the longitudinal dynamics depending on the at least one regulating parameter. A first sensor determines the vehicle speed, a second determines the drive torque, a third determines the operating state of the at least one permanent brake, a fourth determines information about the preceding vehicle and an analysis/adjustment/regulating unit analyzes the speed, the drive torque, the operating state of the at least one permanent brake and the information about the preceding vehicle, adjusting the at least one regulating parameter and regulating the vehicle longitudinal dynamics depending on the at least one regulating parameter.
