Abstract: A system includes a camera housing and a control device associated with an autonomous vehicle. The camera housing houses a camera, and is mounted to an autonomous vehicle. The camera housing comprises a glass positioned in front of the camera. The glass is coated with a set of materials comprising a hydrophobic material and an anti-reflective material. The set of materials is configured to reduce ghosting effect on an image captured by the camera. The camera housing further comprises a top portion and a bottom portion. The top portion extends beyond the bottom portion to form a tilt angle. The tilt angle is configured to reduce indirect light from coming into a field of view of the camera. The processor facilitates autonomous driving of the autonomous vehicle using at least the image. The ghosting effect is reduced in the image due to using the set of materials.

Abstract: A system for granting access to an autonomous vehicle comprises the autonomous vehicle, a control device, and a communication device associated with the autonomous vehicle. The communication device receives a signal from a device associated with a user that indicates the user requests the autonomous vehicle to pull over. The control device pulls the autonomous vehicle over to a side of road traveled by the autonomous vehicle. The control device receives a credential associated with the user. The control device determines whether the credential is verified. In response to determining that the credential is verified, the control device grants the user to access the autonomous vehicle.

Abstract: Techniques are described for transitioning control of a steering system from an autonomous mode in a vehicle to a driver-controlled mode where the driver can control the steering wheel of the steering system. A method includes receiving values that describe an amount of torque and a direction of torque in response to a torque applied to a steering wheel of a steering system operated in an autonomous mode, determining that the values are either greater than or equal to a threshold value or are less than or equal to a negative of the threshold value, determining that the values are measured over a period of time greater than or equal to a pre-determined amount of time, and transitioning the steering system from being operated in the autonomous mode to being operated in a driver-controlled mode in which the steering system is under manual control.

Abstract: Devices, systems, and methods for a vehicular safety system in autonomous vehicles are described. An example method for safely controlling a vehicle includes selecting, based on a first control command from a first vehicle control unit, an operating mode of the vehicle, and transmitting, based on the selecting, the operating mode to an autonomous driving system, wherein the first control command is generated based on input from a first plurality of sensors, and wherein the operating mode corresponds to one of (a) a default operating mode, (b) a minimal risk condition mode of a first type that configures the vehicle to pull over to a nearest pre-designated safety location, (c) a minimal risk condition mode of a second type that configures the vehicle to immediately stop in a current lane, or (d) a minimal risk condition mode of a third type that configures the vehicle to come to a gentle stop.

Abstract: Technique for performing camera calibration on a vehicle is disclosed. A method of performing camera calibration includes emitting, by a laser emitter located on a vehicle and pointed towards a road, a first laser pulse group towards a first location on a road and a second laser pulse group towards a second location on the road, where each laser pulse group includes one or more laser spots. For each laser pulse group: a first set of distances are calculated from a location of a laser receiver to the one or more laser spots, and a second set of distances are determined from an image obtained from a camera, where the second set of distances are from a location of the camera to the one or more laser spots. The method also includes determining two camera calibration parameters of the camera by solving two equations.

Abstract: Devices, systems and methods for controlling an exterior and dashboard lights of an autonomous vehicle are described. One example of a method for controlling one or more exterior lights includes receiving, from an autonomous driving system (ADS) of the vehicle, an input to control one or more exterior lights that are part of a lighting system of the vehicle, and transmitting, based on the input, a message to a controller area network (CAN) bus of the lighting system, the message being further based on a driver command upon a determination that a driver-initiated message is received. In an example, the lighting system of the vehicle further comprises a plurality of dashboard lights.
