Method for regulating the longitudinal dynamics of a motor vehicle

摘要

The invention relates to a method (24) for longitudinal dynamics control of a motor vehicle (2), in which a target acceleration value (28) is provided and a pilot control torque (36) is created by means of a pilot control (34) on the basis of the target acceleration value (28). The pilot torque (36) and a compensation torque (38) are added to a target torque (40), and an actuator (18) for influencing the longitudinal dynamics of the motor vehicle (2) is acted upon by the target torque (40), so that Motor vehicle (2) is accelerated, a theoretical acceleration torque (42) being estimated by means of the actuator (18). An inverse feedforward control (60) is used to create a theoretical target acceleration value (58) from the theoretical acceleration torque (42), and an actual acceleration value (44) is recorded. The actual acceleration value (44) and the theoretical target acceleration value (58) are fed to a controller (46), by means of which the compensation torque (38) is created. The invention further relates to a device (20) for regulating the longitudinal dynamics of a motor vehicle (2) and a motor vehicle (2).
