Method of controlling a motor vehicle with an automated clutch device
First Claim
1. A method of controlling a motor vehicle with an automated clutch, with an engine that is actuated by an engine control device, with an actuator-controlled automated transmission, and with at least one electronic control device for actuating the transmission and the clutch, the method including the steps of:
- detecting a quantity that is at least representative of a traveling speed of the vehicle, detecting an actuation of at least one of a brake and a fuel-metering element, detecting an operating state of the engine, taking the clutch out of engagement if the engine is found to be running while the vehicle is found to be traveling at a speed greater than a threshold value, and if at the same time neither the brake pedal nor the fuel-metering element is found to be actuated, and subsequently re-engaging the clutch if at least one of the brake pedal and the fuel-metering element is found to be actuated, wherein prior to said re-engaging of the clutch, a transmission input rpm-rate is determined, and an engine rpm-rate is controlled in such a manner that said engine rpm-rate and said transmission input rpm-rate are brought towards a closer agreement.

Abstract
A method of controlling a motor vehicle with an automated clutch and an automated transmission includes the steps of:
detecting the vehicle speed,
detecting if the brake and/or the gas pedal is actuated,
detecting whether or not the engine is running,
disengaging the clutch if the engine is found to be running while the vehicle is found to be moving faster than a threshold speed, and if at the same time neither the brake nor the gas pedal is found to be actuated, and
subsequently re-engaging the clutch if the brake and/or gas pedal is found to be actuated,
wherein prior to re-engaging the clutch, a transmission input rpm-rate is determined, and an engine rpm-rate is controlled in such a manner that the respective rpm-rates of the engine and the transmission are brought towards a closer agreement.

-
detecting a quantity that is at least representative of a traveling speed of the vehicle, detecting an actuation of at least one of a brake and a fuel-metering element, detecting an operating state of the engine, taking the clutch out of engagement if the engine is found to be running while the vehicle is found to be traveling at a speed greater than a threshold value, and if at the same time neither the brake pedal nor the fuel-metering element is found to be actuated, and immediately beginning to re-engage the clutch if the brake pedal is found to be actuated.

24. A method of controlling a motor vehicle with an automated clutch, with an engine that is actuated by an engine control device, with an actuator-controlled automated transmission, and with at least one electronic control device for actuating the transmission and the clutch, the method including the steps of:
-
a) detecting a quantity that is at least representative of a traveling speed of the vehicle, b) detecting an actuation of at least one of a brake and a fuel-metering element, c) detecting an operating state of the engine, d) detecting whether a current traveling situation indicates a need for engine-braking, and e) if the engine is found to be running while the vehicle is found to be traveling at a speed greater than a threshold value, and if at the same time neither the brake pedal nor the fuel-metering element is found to be actuated;
disengaging the clutch if the result of step d) is negative, preventing disengagement of the clutch if the result of step d) is affirmative. - View Dependent Claims (25, 26, 27, 28, 29)
