Method for controlling longitudinal dynamics of motor car to adjust target speed of motor car at idle travel, involves determining target acceleration depending on weighting factor for lowering sensitivity of controlling process

摘要

The method involves determining a driving state parameter (Zf), which characterizes a driving status of a motor car (100). A target acceleration of the car is determined depending on the driving state parameter and an environmental parameter i.e. object position- and status data vector (Zo) so as to control longitudinal dynamics of the car depending on the target acceleration by an engine control unit and a brake control unit. The target acceleration is additionally determined depending on a weighting factor for lowering sensitivity of controlling process in less critical situations. An independent claim is also included for a motor car comprising a control device for controlling longitudinal dynamics.
