Abstract
A method and a device for automatically deactivating a coasting operating mode in a motor vehicle with an internal combustion engine is disclosed. An activated coasting operating mode is deactivated if the current vehicle speed exceeds a threshold value. The threshold value is set as the sum of a minimum vehicle speed and of a maximum permissible increase in speed.
Claims14
A method for automatically deactivating a coasting operating mode in a motor vehicle with an internal combustion engine, comprising:
- deactivating a coasting operating mode if a current vehicle speed exceeds a threshold value;
- wherein the threshold value is set as a sum of a minimum vehicle speed and a maximum permissible increase in speed;
- and
- setting a coasting prohibition marker for temporarily preventing operation in the coasting operating mode.
1 more element
A method of operating a vehicle in a coasting operating mode, comprising:
- activating a coasting operating mode;
- measuring vehicle speed;
- deactivating the coasting operating mode when a vehicle speed is greater than a minimum speed plus a predefined maximum change in speed, and the predefined maximum change in speed is a non-fixed value dependent on a current vehicle speed;
- and
- setting a coasting prohibition marker for temporarily preventing operation in the coasting operating mode.
