Abstract: A redundant safety controller configured to monitor communications between at least one controller and a by-wire control system. The at least one controller has a first hardware architecture and is configured to manage operation of the by-wire control system. The redundant safety controller has a second hardware architecture. The first hardware architecture is different from the second hardware architecture. The at least one controller is configured to implement a first instruction set architecture. The redundant safety controller is configured to implement a second instruction set architecture. The first instruction set architecture is different from the second instruction set architecture. The redundant safety controller is configured to determine whether the at least one controller has failed and assume management of the operation of the by-wire control system based on the determination.

Abstract: Systems and methods for controlling a vehicle. One example system includes a deceleration actuator coupled to a first wheel of the vehicle and an electronic processor communicatively coupled to the deceleration actuator. The electronic processor is configured to receive a vehicle park command. The electronic processor is configured to, responsive to receiving the vehicle park command, determine a maximum holding pressure threshold.

Abstract: A system for detecting actuator misconfiguration in a vehicle includes actuators and a control module. Each actuator is assigned a unique identifier. The control module includes interface ports in communication with the actuators via serial data links. Each interface port is in communication with two of the actuators. Each actuator is in communication with two of the interface ports. The control module is configured to receive a message from an actuator installed at a location of the vehicle, the message including the unique identifier assigned to the actuator, compare the received unique identifier assigned to the actuator to a stored identifier specific to the location of the vehicle, and in response to the received unique identifier being different than the stored identifier, transmit an error signal indicating a failure associated with the actuator. Other examples systems and methods for detecting actuator misconfiguration in vehicles are also disclosed.

Abstract: A method and apparatus for sensing wheel torque of a highly automated driving (HAD) vehicle includes a wheel hub configured to rotate around a rotation axis as the vehicle moves and a brake caliper, including a brake pad, configured to apply a caliper force to the wheel hub. A reaction carriage is interconnected with the brake caliper and is configured to have a reaction force applied to it when the brake caliper applies the caliper force to the wheel hub. The wheel torque sensor includes a hydraulic chamber having a hydraulic fluid and a pressure sensor, interconnected with the hydraulic chamber, that senses pressure applied to the hydraulic fluid in response to the reaction force.

Abstract: A dual tire pressure monitoring system (TPMS) and wheel torque sensor system generates a single wireless signal containing both tire pressure data and wheel strain data. The wheel strain data is functionally related to wheel torque. The dual sensor has a transceiver that generates the wireless signal for a remote controller. A body of the dual sensor is positioned on the interior of the wheel under the tire, near the valve stem. The wheel torque is used to control braking, propulsion or steering of a Highly Automated Driving (HAD) vehicle, and to improve vehicle stability control and vehicle diagnostics.
