- the perception layer engine 418 also continuously updates that representation.
- the perception layer engine 418 generates this perception layer 424 by using all of the sensor data from the truck 102 as well as from the sensors in the system 100 (i.e., the cameras, radar, localization sensors, etc.).
- the perception layer 424 is a compressed abstraction of the real world that reflects the position, speed and direction of movement (heading) of the truck and all objects within view of the truck’s sensors, including, for example but without limitation, (i) the roads and other drivable areas, lane markings, medians, street signs, bridges, overpasses, toll booths and permanent and temporary barriers, (ii) conditions of the roads and drivable areas such as potholes, wetness, accumulated water or snow, falling rain or snow, oil spills, etc., and (iii) other vehicles, pedestrians, bicyclists, animals, debris, etc. Aspects of the perception layer 424 are used for various features of the applications 420 as needed.
- FIG. 9 is a flow chart 700 showing steps performed in a process performed by the lane keeping application 610 in FIG. 6A.
- the lane keeping application 610 assists the truck 102 to stay within the lane in which it is currently driving.
- the application 610 receives information from the perception layer 424 that represents centerlines and left and right boundaries of lanes a distance ahead of the truck.
- the lane keeping application 610 predicts the path that the truck 102 must follow in order to be centered on the centerline and within the left and right boundaries of the current lane by the time the truck arrives at the distant locations.
- the lane keeping application 610 then automatically controls the truck’s steering by outputting a command via the CAN bus to the steering actuator 130 to steer the truck 102 according to the predicted path and thus keep the truck within the lane. This occurs continuously as the truck is moving to keep the truck within its lane.
- FIG. 10 is a flow chart 720 showing steps performed in a process performed by the adaptive cruise control application 614 in FIG. 6A.
- the adaptive cruise control application 614 assists the truck to maintain a speed of travel input by the driver or a speed of travel automatically determined based on the perception layer 424 as appropriate in view of posted speed limits and environmental conditions.
- the adaptive cruise control application 614 receives information from the perception layer 424 that represents other vehicles and objects ahead of and adjacent to the truck.
- the adaptive cruise control application 424 analyzes the information to determine if the truck needs to slow down in order to maintain a safe distance from any such object.
- the adaptive cruise control application 614 decreases the speed of the truck by using one or more of releasing the throttling, applying engine brakes or applying foundation brakes. This is accomplished by sending a command via the CAN bus to the corresponding actuators of the truck. Additionally, after the truck has been slowed, if information from the perception layer 424 indicates that there no longer are objects requiring the truck to stay at the slower speed (and thus can return to the original speed or a speed between the slower speed and the original speed), then the adaptive cruise control application 614 increases speed by automatically releasing any brakes that may be engaged and applying throttling.
- the adaptive cruise control application 614 is capable of taking the truck to a full stop, if needed, and then initiating throttling to return to an appropriate speed thereafter, including, for example, operating fully automatically in stop-and-go traffic.
- FIG. 11 is a flow chart 740 showing steps performed in a process performed by the lane aware navigation application 618 in FIG. 5.
- the lane aware navigation application 618 uses data provided from the perception layer 424 to more accurately determine precise navigational instructions, at a lane level. This enables the ability to inform the truck operator miles in advance if the truck is in the correct lane or not, and whether or not one or multiple lane changes are necessary, in order to successfully take an exit or make a turn.
- the lane aware navigation application 618 recommends when a left or right lane change should be made, and when it is safe to do so, by utilizing information from the perception layer 424, which may also include the weight and length of the truck.
- This lane aware navigation application 618 uses information from the perception layer 324 to determine this and thus guide the operator to avoid or stay in the current lane and thus avoid making an unnecessary lane change or a needed lane change too late and thus hastily.
- the lane aware navigation application 618 therefore helps reduce the total amount of lane changes needed, and also helps to provide that lane changes are made on time and thus more safely, and therefore helps reduce the potential accident likelihood.
- the lane aware navigation application 618 may work in conjunction with any of the lane change applications described further below to fully or partially automate any needed lane change. [0082] Automated Electronic Logging

- FMCSA Federal Motor Carrier Safety Administration
- the automated electronic logging application 622 addresses these requirements with fewer interactions than prior systems.
- the automated electronic logging application 622 uses information from the perception layer 424 along with the CAN bus 120 data connected to the controller 400 to determine each of four driving states: On-Duty Driving, On-Duty Not-Driving, Sleeper Cab, Off-Duty.
- On-Duty Driving state is automatically determined by utilizing CAN bus 120 wheel speed/motion information with output of the perception layer 424 and the driver facing camera 326 (and second driver facing camera) in the sun visor 304 for additional verification.
- On-Duty Not- Driving state is automatically determined by utilizing CAN bus 120 data sources such as the vehicle ignition switch, selected transmission gear, tractor and trailer parking brakes, as well as information outputs from the perception layer 424 that recognize whether the vehicle operator has exited the truck through either side door. Additional confirmation through a driver facing camera 326 may be used if the sun visor 304 is in its lowered (open) position, or through a second driver facing camera if the sun visor 304 is in its upper (closed) position.
- a verification for whether a driver is entering a warehouse for a delivery he/she is performing, or whether the driver has finished his/her duty for the day may be requested through the touch screen interface 314, or by using a mobile application installed on a device carried by the driver, such as a smartphone, or a fleet manager from a remote work station.
- Sleeper Cab state is automatically determined through the detection of additional power/current draw from the vehicle’s batteries, or an auxiliary power generation source.
- Additional confirmation through the driver facing camera 326 may be used if the sun visor 304is in its lowered (open) position, or through a second driver facing camera if the sun visor 304 it in its upper (closed) position, and/or by providing motion detection sensors in the sleeper area of the cab connected to the system 100.
- the GPS location of the truck may be used to verify a map location point-of-interest that matches to a truck stop, parking lot, gas station, etc.
- Off-Duty state is automatically determined in similar methods to that of On-Duty Not-Driving state, where a driver exiting the truck near the driver’s 11 -hour daily limit can be assumed to be finishing his or her work for the day. Additional information may be used in making the determination of driving state, including location information from a driver’s smartphone.

Programming for controlling the color of the driving lights 1250 can be provided so that certain colors signify certain states. For example, but without limitation, the color red can be used to signify that the truck is waiting to be loaded, the color green can be used to signify that the truck is waiting to be unloaded, the color yellow can be used to signify that the truck is currently being unloaded, and the color purple can be used to signify that the truck is being remotely piloted. Other states can also be signified with light colors. Additionally, states can be signified not only by color but also by blinking patterns of the lights.
- the driving lights 1250 also cast light out through the front side of front deflector portion 1221.
- the areas of the hardware module 1228 and front deflector portion 1221 at which the cameras 1228, 1230, 1234 and thermal vision sensor 1218 peer through, and at which the driving lists 1250 cast out light, are individually and collectively hereinafter referred to as “View Openings.”
- the shield 1223 is configured and shaped to cover the View Openings.
- the shield 1213 is comprised generally of an opaque material, but has localized areas, view windows 1260, corresponding with the View Openings and which are transparent so as not to block the ability of the cameras and sensor to peer through, and the driving lights to cast light through, the shield 1223.
- the shield 1223 is comprised of a transparent polycarbonate material.
- An opaque or semi-transparent coating may be applied to the back side of the shield 1223 except at the areas defining the view windows 1260 so that the view windows 1260 remain transparent.
- the entirety of shield 1223 may be kept transparent.
- the shield 1223 is comprised of an opaque or semi transparent material and openings corresponding to windows 1260 are formed in shield 1223 into which pieces of transparent material, such as a polycarbonate, are inserted and secured to create windows 1260. In the latter embodiment, the material out of which the pieces of transparent material defining windows 1260 are made may be different from one another.
- the material for windows 1260 for cameras 1228, 1230, 1234 may be polycarbonate and the material for window 1260 for thermal vision sensor 1218 may be germanium or silicon. Any suitable material may be used for the windows 1260, and may differ from one window to another as best suited for the camera, sensor or light in question.
- the material forming windows 1260 could cause refraction affecting the accuracy or other performance characteristics of the cameras or sensors. In that event, the cameras and/or sensors could be calibrated to correct for any unwanted refraction.
- an insect deflector mounted on the wind deflector body 1204 adjacent to each forward facing camera 1208 and thermal vision sensor 1218.
- the insect deflectors reduce or prevent accumulation of insects or other debris on windows 1260 associated with the cameras 1208 during operation.
- one or more shield wipers 1270 may be mounted on the wind deflector body 1240 adjacent to the hardware module 1228 to wipe away or otherwise clear rain, moisture, insects, dust, debris or any other liquid or solid from the windows 1260 associated with the forward facing cameras 1208 and, if desired window(s) associated with the thermal vision sensor 1218. In one embodiment as shown in FIG.
- shield wiper 1270 positioned to wipe all the windows 1260 associated with the three forward facing cameras 1208 and the thermal vision sensor 1218.
- the wiper may rotate in an oscillating, back and forth motion or, for example, may rotate in one direction for 360° and then continue to repeat the circular motion.
- the two shield wipers 1270 may be situated so that the blades extend in opposite directions in the resting position, as shown in FIG. 32.
- the shield wipers 1270 may be situated so that the blades extend towards each other in the resting position, as shown in FIG. 33. In the latter configuration, it may be necessary for the ends of the blades to overlap, as shown in FIG. 33, to ensure they extend across all intended windows 1260 during operation.
- the shield wipers 1270 may operate with offset timing. Any number, arrangement and motion of shield wipers 1270 may be used to achieve the desired effect of clearing the windows.
- the shield wipers 1270 are recessed into the wind deflector body 1204 when not in use (i.e., in “off’ state), and a linear motor is be used to extend the shield wipers 1270 out of the wind deflector body 1204 for use (i.e., in “on” state).
- This embodiment helps to make the deflector body 1204 more aerodynamic when the shield wipers 1270 are in the off state, and thus in the recessed position.
- the contour of the outer surfaces of the shield wipers 1270 may be configured to match the contour of the outer surface of the wind deflector body 1204 had the shield wipers not been present, so that, when the shield wipers are in the recessed position, the outer surface of the wind deflector is smooth.
- the outer surface of the shield wipers 1270 may have the same color and finish as the outer surface of the wind deflector body 1204 so that they blend in and their presence is less obvious to an onlooker.
- the wind deflector portion 1200 also includes a map database unit 1430.
- the map database unit 1430 is stored locally on a hard drive and updated via LTE or Wi-Fi connectivity.
- the map database unit 1430 is a HERE Maps database. Alternative map database units with similar specifications or any suitable specifications may be used.
- the map database unit 1430 is connected to and provides an output to programming in the controller 1400.
- the wind deflector portion 1200 operates in system 100 generally in the same was as described for the wind deflector portion 200 in connection with FIGS. 4A and 4B.
- the front facing cameras 1208, the rear facing cameras 1212 and 1216, the side facing cameras 1230 and 1234 and the radar units 1254 are connected to and provide their output to the controller 1400.
- the controller 1400 is operable to run various programming 1406 including an operating system, such as real-time embedded Linux, and other programs and applications as described herein.
- the operating system may include APIs and/or a marketplace/app-store for outside developers to support cross-platform integrations.
