Control unit for starting control of commercial vehicle, has comparison element for determining lower value of two clutch moment gradients as clutch moment target gradient and transmitting actuating signal to clutch actuator of clutch

摘要

The unit has a clutch control circuit (1) for adjusting clutch moment of a clutch, and a motor control circuit (2) for adjusting motor torque produced by a drive motor. A maximum clutch moment gradient is determined in a full load branch (3) under consideration of dynamic operational characteristics of the drive motor. A clutch moment gradient is determined based on performance requirement of a driver. A comparison element (5) determines lower value of two clutch moment gradients as a clutch moment target gradient and transmits an actuating signal to a clutch actuator of the clutch. The drive motor is designed as a turbo-loaded diesel combustion engine, and the clutch is designed as an automated friction clutch e.g. single plate dry clutch and multi-plate dry clutch, or a hydrodynamic clutch e.g. turbo-coupling clutch and hydrodynamic torque converter.
