Abstract
A vehicular driving control system and a method for operating the same are provided, may include an information provider to provide information on a front road of a vehicle, a transmission controller to control gear shifting by predicting a condition on the front road based on the information on the front road, and a diagnosing device to diagnose a failure status by comparing the information on the front road with real front road information measured by a sensor, and to restrict a predictive gear-shifting controlling operation of the transmission controller, according to a result of the diagnosing.
Claims17
A vehicular driving control system comprising:
- an information provider configured to provide information on a front road of a vehicle;
- a transmission controller configured to control gear shifting of the vehicle by predicting a condition on the front road, according to the information on the front road;
- and
- a diagnosing device configured to:
- diagnose a failure status by comparing the information on the front road with real front road information measured by a sensor, wherein diagnosing the failure status includes determining failure as being caused;
- restrict a predictive gear-shifting controlling operation of the transmission controller, according to the diagnosing of the failure status,
- wherein the diagnosing of the failure status further includes:
- determining an information difference between predicted front road information based on the information on the front road and the real front road information measured by the sensor;
- determining a failure status as being caused when the information difference is equal to or greater than a first threshold value;
- determining a failure level when the failure status has been determined as being caused;
- wherein the failure level is determined from a plurality of failure level options, and each of the plurality of failure level options is matched with an adding count that is non-zero and different from the adding counts matched with the other failure level options,
- setting the adding count depending on the failure level;
- and
- increasing a failure count based on by adding the adding count whenever the failure level is determined.
A method for operating a vehicular driving control system, the method comprising:
- controlling, by a transmission controller, gear shifting by predicting a condition on a front road according to information on the front road, which is provided from an information provider;
- diagnosing, by a diagnosing device, a failure status by comparing the information on the front road with real front road information measured by a sensor, wherein diagnosing the failure status includes determining failure as being caused;
- restricting, by the diagnosing device, a predictive gear-shifting controlling operation of the transmission controller, according to the diagnosing of the failure status,
- wherein the diagnosing of the failure status further includes:
- determining, an information difference between predicted front road information based on the information on the front road and the real front road information measured by the sensor;
- determining, a failure status as being caused when the information difference is equal to or greater than a first threshold value;
- determining a failure level when the failure status has been determined as being caused,
- wherein the failure level is determined from a plurality of failure level options, and each of the plurality of failure level options is matched with an adding count that is non-zero and different from the adding counts matched with the other failure level options;
- setting the adding count depending on the failure level;
- and
- increasing a failure count by adding the adding count when a valid failure is determined.
