Abstract: Systems and methods to park a semi-autonomous follower vehicle involve performing path planning to determine a path from a current location of the follower vehicle to a parking space, and controlling longitudinal movement of the follower vehicle using an accelerator control mechanism and a brake control mechanism operated by a driver of a leader vehicle that is not physically coupled to the follower vehicle. The accelerator control mechanism includes a pedal, knob, or lever and the brake control mechanism includes a pedal, knob, or lever. Lateral movement of the follower vehicle is controlled in order to follow the path to the parking space.

Abstract: A system and method to perform automatic alignment of an optical sensor of a vehicle involve disposing two or more active targets at known locations in an alignment station. Each of the two or more active targets have at least two visibly different states. The method includes coding a change among the at least two visibly different states for the two or more active targets. Images obtained by the optical sensor of the two or more active targets are processed to identify features and perform the alignment of the optical sensor with another sensor of the vehicle or with the vehicle.

Abstract: A method and system to perform dynamic demosaicing for a camera in a vehicle involve an array of image sensors of the camera to obtain light intensity values. Each image sensor of the array of image sensors represents a pixel. An array of filters of the camera overlays the array of image sensors and restricts a wavelength range for which the one image sensor of the array of image sensors obtains the light intensity value. The array of filters includes at least two different types of filters corresponding with two different wavelength ranges. A processor estimates a current state associated with the vehicle and selects a demosaicing algorithm based on the current state such that, for each pixel, the demosaicing algorithm facilitates an estimate of the light intensity value at a different wavelength range than the wavelength range for which the corresponding image sensor obtained the light intensity value.

Abstract: A system includes an impairment sample module, impairment value calculator module, threshold comparison module, warning alert module, and intervention module. The impairment sample module may be configured to obtain a first impairment sample for an operator of a vehicle while the vehicle is running. The impairment value calculator module may be configured to calculate a first impairment value based on the first impairment sample. The threshold comparison module may be configured to compare the first impairment value to a first threshold value corresponding to a first range of impairment and a second threshold value corresponding to a second range of impairment. The warning alert module may be configured to generate a warning alert in response to determining that the first impairment value exceeds the first threshold value. The intervention module may be configured to execute driver intervention protocol if the first impairment value exceeds the second threshold value.

Abstract: A drive control system of a vehicle includes a vehicle speed module configured to determine whether the vehicle is moving and set a state of a signal based on the determination. A shift control module is configured to shift a transmission of the vehicle based on a signal from a range selector. Independently of the signal from the range selector, the shift control module is configured to selectively shift the transmission of the vehicle based on a signal from a combination park and ignition switch and the signal from the vehicle speed module. An ignition control module is configured to selectively shut down an engine of the vehicle based on the signal from the combination park and ignition switch and the signal from the vehicle speed module.

Abstract: An override system of a vehicle includes a command module configured to: receive a concentration of a chemical in a driver's body measured using a chemical measurement device of the vehicle; and when the concentration of the chemical is greater than the predetermined concentration of the chemical, prevent movement of the vehicle. An override module is configured to, in response to receipt of user input indicative of an override request while the concentration of the chemical is greater than the predetermined concentration of the chemical, selectively generate a command to override the prevention of movement of the vehicle. The command module is further configured to, in response to the command, selectively allow movement of the vehicle.
