The radar sensor is a device which detects a location of an object by use of a reflected wave generated by emission radiation of a radio wave when transmission and reception are performed in the same place.
To prevent a difficulty in distinguishing a transmitted radio wave and a received radio wave due to the transmitted radio wave and the received radio wave overlapping each other, the radar sensor utilizes a Doppler effect, changes a frequency of the transmitted radio wave according to a time, or outputs a pulse wave as the transmitted radio wave.
For reference, the LiDAR sensor has higher detection accuracy in a lateral direction as compared with a radio detecting and ranging (RaDAR) sensor, improving accuracy of determining whether a path is present ahead.

The autonomous driving control apparatus 180 controls autonomous driving of the vehicle based on input information related to the inputter, image information related to the image acquirer 172, detection information related to the distance detector 171, detection information related to the speed detector 174, and location information related to the location receiver 173.
The autonomous driving control apparatus 180 may be a driving control apparatus having an HDA function of performing autonomous driving when a current location of the vehicle of the vehicle is a highway and releasing an autonomous driving mode when the current location of the vehicle is a road which is not a highway.
The autonomous driving control apparatus 180 may further include the storage 182 in addition to the controller 181 and may further include a communicator configured to receive information from the image acquirer 172, the distance detector 171, the location receiver 173, and the speed detector 174.
The communicator may include at least one component configured for communicating with various devices in the vehicle, and for example, may include at least one of a short-range communication module, a wired communication module, and a wireless communication module.
When a selection signal of a navigation mode selected through the input portion 131 of the terminal is received, the controller 181 confirms a current location of the vehicle received by the location receiver 173, confirms a destination of the vehicle selected through the input portion of the terminal, confirms map information stored in the storage 182, searches for a route from the current location to the destination, matches the found route to a map, and displays the map, to which the route is matched, on the display portion 132 of the terminal.
When a selection signal of an autonomous driving mode is received, the controller 181 activates operations of the image acquirer 172 and the distance detector 171, performs interworking with a navigation mode, and controls driving of various driving devices based on navigation information, image information, distance information, and speed information to allow the vehicle to autonomously travel from the current location to the destination.
During the autonomous driving mode, the controller 181 confirms a location of the other vehicle travelling in a lane in a left direction or a right direction of a lane of the vehicle based on distance information to an obstacle detected by the distance detector 171, confirms a distance to the other vehicle corresponding to the confirmed location of the other vehicle, and adjusts a speed of the vehicle based on the confirmed distance of the other vehicle.
When image information related to a road is received during the autonomous driving mode, the controller 181 performs image processing, recognizes a lane of the road, and recognizes a lane in which the vehicle travels based on location information related to the recognized lane.
During the autonomous driving mode, the controller 181 controls a driving (steering) direction of the vehicle to maintain or change a lane based on a distance to the other vehicle, a current location of the vehicle, a recognized lane, a recognized carriageway, and a found route.
During the autonomous driving mode, the controller 181 may also display images in front, back, left and right directions of the vehicle acquired by the image acquirer 172 and may also display map information and road guidance information, to which a route is matched, by interworking with the navigation mode.
Here, navigation information includes destination information and map information and further includes a name of a road, location information related to the road, a kind of the road, and a route number of the road in a map.
Furthermore, when a highway driving mode is selected, the controller 181 determines whether the vehicle has entered a highway based on the navigation information and the location information. When it is determined that the vehicle has entered the highway, the controller 181 controls autonomous driving on the highway using the HDA function. When it is determined that the vehicle has exited the highway, the controller 181 exits the highway driving mode.
Furthermore, when the autonomous driving mode is released, the controller 181 performs a manual driving mode. That is, during the manual driving mode, the controller 181 may adjust a speed of the vehicle by controlling a power device and a brake based on operation information related to a brake pedal and operation information related to an accelerator pedal, which are operated by a driver. Furthermore, the controller 181 may adjust a driving direction of the vehicle by controlling a steering device based on steering information related to the steering wheel operated by the driver.
When image information acquired by the image acquirer is received, the controller 181 may also process and recognize an image to recognize a toll gate, a high pass lane, and a toll ticket lane and recognize a speed restriction section.
The controller 181 may also recognize a speed restriction section, a school zone, and a curvy road based on navigation information.
During the autonomous driving mode, the controller 181 compares a current location of the vehicle with a preset location. When it is determined that the current location is the preset location, the controller 181 reduces revolutions per minute (RPM) of an engine or controls braking of the brake to reduce a driving speed.
When the driving speed is reduced, the controller 181 may check a speed limit corresponding to a characteristic of a location and control the driving speed to be reduced based on the checked speed limit.
Here, the speed limit corresponding to the characteristic of the location may include a speed limit of a tollgate entry section and may further include a speed limit on a curvy road, a speed limit on a speed bump, and a speed limit in a school zone.
During the autonomous driving mode or the manual driving mode, the controller 181 may control operation of the suspension to adjust a height of the vehicle body and a damping force based on a surface state of a road.
That is, when the surface state is an uneven state or a speed bump is present, the controller 181 controls the suspension to reduce a damping force of a damper. When the surface state is an even state, the controller 181 controls the suspension to increase the damping force of the damper.
When the vehicle travels on the toll ticket lane in the manual driving mode, the controller 181 controls the opening and closing device to open a window adjacent to a driver seat of the vehicle and controls the suspension to adjust the height of the vehicle body based on a height of a toll ticket dispenser.
The controller 181 confirms a distance between a current location of the vehicle and a destination. When it is determined that the distance between the current location and the destination is a reference distance, the controller 181 controls the radio to be turned off, controls an audio device to be turned off, and controls the operation of the suspension to adjust the height of the vehicle body.
When it is determined that the current location is spaced the reference distance from the destination, i.e., the current location is near the destination, the controller 181 may control at least one of the air conditioner, the radio, the audio device, and the suspension.
The controller 181 compares location information related to the current location with location information related to the destination. When it is determined that the current location is the destination, the controller 181 confirms illuminance detected by the illumination detector. When it is determined that the confirmed external illuminance is less than or equal to a reference illuminance, the controller 181 controls the opening and closing device to open a window.
When it is determined that the current location is the destination, the controller 181 confirms the illuminance detected by the illumination detector and a temperature detected by the temperature detector. When the confirmed external illuminance is less than or equal to the reference illuminance and the confirmed temperature is greater than or equal to reference temperature, the controller 181 controls operation of the opening and closing device to open the window.
Furthermore, a setting of window opening during parking according to an external temperature may be selected or released by a user.
When it is determined that the current location is the destination, the controller 181 determines whether the auto hold function and the ISG function are being performed. When it is determined that the auto hold function and the ISG function are being performed, the controller 181 may release the auto hold function and may also release the ISG function.
When it is determined that the current location is the destination, the controller 181 may also control operation of the steering device to set a turning radius and a gear ratio that facilitate parking.
In the case of a vehicle including a rear wheel steering (RWS) device, the controller 181 controls the RWS device such that the vehicle has a turning radius that facilitates parking.
In the case of a vehicle including an active front steering (AFS) device, the controller 181 sets a steering ratio of the AFS device to be a gear ratio that facilitates parking.
Here, the turning radius and the gear ratio may be set by a user.
The controller 181 may be a central processing unit (CPU), a main control unit (MCU), or a processor.
The controller 181 may be implemented as a memory configured to store data on an algorithm for controlling operations of components in the vehicle or store data on a program for reproducing an algorithm, and a processor configured to execute such an operation using the data stored in the memory. In the instant case, each of the memory and the processor may be implemented as a separate chip. Alternatively, the memory and the processor may be implemented as a single chip.
The storage 182 stores map information, a name of a road, a kind of the road, a route number of the road, and location information related to the road in a map and stores location information and image information related to a preset location.
The preset location may be a tollgate, a curvy road with a curvature greater than or equal to a preset curvature, a speed bump, or a school zone.
The storage 182 may store location information related to a destination of the vehicle and may also store a reference distance for determining the vicinity of the destination.
The storage 182 may be implemented as at least one of a non-volatile memory device such as a cache memory, a read-only memory (ROM), a programmable ROM (EPROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), or a flash memory, a volatile memory device such as a random access memory (RAM), and a storage medium such as a hard disk drive (HDD) or a CD-ROM, but the present invention is not limited thereto. The storage may be a memory implemented as a chip separate from the processor described above in connection with the controller and may be implemented as a single chip together with the processor.
The storage 182 stores reference illuminance and reference temperature.
The storage 182 may also store a turning radius of the RWS device or a gear ratio of the AFS device.
At least one component may be added or removed according to performances of the components of the vehicle shown in
