Abstract: A number of illustrative variations may include a method for use in a vehicle having an electronic steering system, a position control module, an electronic steering system rack force observer, and a rack force observer vehicle diagnostic, wherein the method includes the steps of providing a vehicle that may include an electronic steering system, a position control module, an electronic steering system rack force observer, and a rack force observer vehicle diagnostic; measuring the steering angle and steering velocity of the vehicle; communicating a steering angle of the vehicle to the position control module and the electronic steering system rack force observer; communicating a steering velocity of the vehicle to the electronic steering system rack force observer; communicating electronic steering system motor commands to the electronic steering system rack force observer; and estimating rack force data and communicating the rack force data to the rack force observer vehicle diagnostic; and determining a co

Abstract: In a number of illustrative variations, a method may include the steps of providing a vehicle that may include at least one sensor; providing at least one signage constructed and arranged to convey a known geolocation of the at least one signage to the at least one sensor; determining a detected geolocation of the vehicle via the at least one sensor; reading the known geolocation of the at least one signage; comparing the detected geolocation to the known geolocation; and identifying discrepancies between the detected geolocation and the known geolocation.

Abstract: A number of illustrative variations may include the steps of providing a first vehicle including at least one sensor, a controller configured to process sensor data, and a vehicle communication system; providing a driving surface having an actual coefficient of friction; determining at least one estimated driving surface coefficient of friction; communicating the at least one estimated driving surface coefficient from the first vehicle to the vehicle communication system; and communicating the at least one estimated driving surface coefficient from the vehicle communication system to at least one other vehicle directly or indirectly.

Abstract: A number of illustrative variations may include a method of diagnosing and/or calibrating components in vehicles.

Abstract: A rear automatic braking system is automatically overridden and released if the accelerator pedal is depressed with the rate of change which is greater than empirically determined threshold beyond a predetermined percentage of its travel for at least a predetermined length of time and if the vehicle's brake pedal is not depressed.

Abstract: A number of illustrative variations may include a method or product for monitoring and responding to component, system, or module changes in an autonomous driving system.

Abstract: A trigger event is detected based on a vehicle malfunction that limits maneuverability of a vehicle. An alert message is generated based on the detected trigger event, and the alert message is broadcast via a Vehicle-to-Everything (V2X) communication. Based on the detected trigger event, a receive channel mask and a transmit channel mask are generated, and a channel mask flag is set. When the channel mask flag is set, one or more incoming message channels are selected based on the incoming channel mask and the channel mask flag, and incoming V2X messages are received and processed only on the selected one or more incoming message channels. When the channel mask flag is cleared, incoming V2X messages are received and processed on the selected one or more incoming message channels and at least one additional incoming message channel.

Abstract: A rear automatic braking system is automatically overridden and released if the accelerator pedal is depressed with the rate of change which is greater than empirically determined threshold beyond a predetermined percentage of its travel for at least a predetermined length of time and if the vehicle's brake pedal is not depressed.

Abstract: A brake system for a motor vehicle includes a first control module coupled to a first hydraulic brake circuit and a second hydraulic brake circuit. The first control module is configured to control fluid pressure within both the first hydraulic brake circuit and the second hydraulic brake circuit. A second control module coupled to the first hydraulic brake circuit and the second hydraulic brake circuit, wherein the second control module is configured to control fluid pressure within both the first hydraulic brake circuit and the second hydraulic brake circuit independent of the first control module. The first control module is disposed in series with the second control module in the first hydraulic brake circuit and the second hydraulic brake circuit.
