Abstract
The present disclosure relates to a driver assistance system having a controller and a method of controlling the driver assistance system. The driver assistance system may include: at least one sensor; a driving device configured to be controlled on the basis of a sensing result by the sensor; and a controller configured to control the driving device by providing a control signal generated on the basis of information from the sensor, and to determine a point to read information from the sensor in response to an event signal based on a predetermined condition provided from the sensor. Accordingly, it is possible to quickly obtain information with small load, thereby effectively controlling the system.
Claims16
A controller comprising:
- a sub-controller configured to control an external driving device by providing a control signal generated on the basis of information from at least one sensor, and to determine a point to read information from the sensor in response to an event signal based on a predetermined condition provided from the sensor,
- wherein the sub-controller operates in one of an interrupt mode in which the sub-controller reads information from the sensor in real time and a polling mode in which the sub-controller periodically reads information from the sensor in accordance with a predetermined polling period.
A driver assistance system comprising:
- at least one sensor;
- a driving device configured to be controlled on the basis of a sensing result by the sensor;
- and
- a controller configured to control the driving device by providing a control signal generated on the basis of information from the sensor, and to determine a point to read information from the sensor in response to an event signal based on a predetermined condition provided from the sensor,
- wherein the controller operates in one of an interrupt mode in which the sub-controller reads information from the sensor in real time and a polling mode in which the sub-controller periodically reads information from the sensor in accordance with a predetermined polling period.
A method of controlling a driver assistance system, the method comprising:
- receiving a signal from at least one sensor;
- determining whether information sensed by the sensor satisfies a predetermined condition in response to the signal;
- reading the information in real time when the information satisfies the condition, and waiting a predetermined period and then reading the information when the information does not satisfy the condition;
- and
- controlling an external driving device by providing a control signal generated by processing the information to the driving device.
