In accordance with an exemplary embodiment, methods and systems are provided for controlling automatic overtake functionality for a host vehicle. In on such exemplary embodiment, a disclosed method includes: (i) obtaining, via a plurality of sensors, sensor data pertaining to the host vehicle and a roadway on which the host vehicle is traveling; (ii) determining, via a processor, when an automatic overtake is recommended, using the sensor data in conjunction with one or more threshold values; (iii) receiving driver inputs pertaining to the automatic overtake; and (iv) adjusting, via the processor, the one or more threshold values for the automatic overtake based on the driver inputs.

Method and system to adapt overtake decision and scheduling based on driver assertions

Methods and systems are provided for providing fault notifications for vehicles. A notification unit is configured to provide a notification when a fault is detected for a vehicle. A processor is coupled to the notification unit, and is configured to provide instructions to the notification unit to provide the notification when the fault is detected, and restrict operation of the vehicle, when the fault is detected, until an action is taken in response to the notification.

Fault notifications for vehicles

A system includes first and second modules of a vehicle. The first module stores at least one seed value, calculates a key based on the at least one seed value, forms a seed key pair based on the calculated key and the at least one seed value, generates a data bus message including the seed key pair and data corresponding to operation of the first module, and transmits, over a distributed vehicle network, the data bus message. The second module receives the data bus message over the distributed vehicle network, retrieves the seed key pair from the data bus message, determines whether the calculated key matches an expected key, and selectively verifies integrity of the first module based on the determination of whether the calculated key matches the expected key.

Method of performing microprocessor ALU integrity test over a distributed asynchronous serial communication network for ASIL-D level safety critical applications

A position diagnostic test for a shift-by-wire system is provided. The shift-by-wire system includes a shift lever configured to move along a shift path, a first and a second position sensor configured to generate a first and a second position signal, respectively, of the shift lever along the shift path, and a controller configured to receive the first and second position signals. The first position sensor includes a first x-coordinate value and a first y-coordinate value, and the second position sensor includes a second x-coordinate value and a second y-coordinate value. The position diagnostic test includes performing a rationality test on each of the coordinate values. If at least one predetermined condition exists for a particular coordinate value, then it fails the rationality test, and the position signal containing the coordinate value may be disregarded.

There is provided a method and system for facilitating communications between a remote access point and a mobile platform during a shutdown period. The mobile platform is equipped with a first receiver and a wireless communications receiver. A wake-up signal is wirelessly transmitted from a remote wireless device to the first receiver of the mobile platform. The communications receiver is activated based upon the wake-up signal. The remote access point is controlled to communicate with the communications receiver subsequent to the activation of the communications receiver.

Method and system for facilitating communication of information to a mobile platform

There is provided a method for selectively communicating from a remote system to a subset of a plurality of vehicles. Each of the vehicles is equipped with a first wireless communications device and a second wireless communication device. The method comprises broadcasting a common message from the remote system to the vehicles via the first wireless communication device. A subset of the plurality of vehicles is selected based upon the common message. A communications link is established between the remote system and the second wireless communication device of each of the selected subset of vehicles to transmit formatted electronic data therebetween.
