Abstract
A method for determining a setpoint acceleration of a motor vehicle and for outputting the determined setpoint acceleration for automatically starting the motor vehicle by an autonomous cruise control system is provided. The method has a first step of ramping up a setpoint acceleration from a first value to a second value. The method has a second step of holding the setpoint acceleration at the second value. The method has a third step of ramping up the setpoint acceleration from the second value to a target acceleration value.

A method for determining a setpoint acceleration of an internal combustion engine of a motor vehicle and for outputting the setpoint acceleration for automatically starting the motor vehicle by an adaptive cruise control system, the method comprising:
- ramping up the setpoint acceleration of the internal combustion engine from a first value to a second value;
- holding the setpoint acceleration of the internal combustion engine at the second value such that running-up of the internal combustion engine is effected;
- and
- ramping up the setpoint acceleration of the internal combustion engine from the second value to a target acceleration value and controlling movement of the motor vehicle based on the second value of the setpoint acceleration and the target acceleration value.
A motor vehicle comprising a closed-loop controller, configured to determine a setpoint acceleration of an internal combustion engine and output the setpoint acceleration for automatically starting the motor vehicle by an adaptive cruise control system, and a torque conversion unit, connected to the closed-loop controller, that is designed to receive the setpoint acceleration output by the closed-loop controller and, based on the setpoint acceleration, to ramp up the setpoint acceleration of the internal combustion engine from a first value to a second value, hold the setpoint acceleration of the internal combustion engine at the second value such that running-up of the internal combustion engine is effected, and ramp up the setpoint acceleration of the internal combustion engine from the second value to a target acceleration value, determine at least one of a setpoint driving torque and a setpoint braking torque and to output the at least one of the setpoint driving torque and the setpoint braking torque to the motor vehicle.
