Abstract: A system includes a steering-system motor, a first electronic control unit (ECU) and a second ECU each electrically connected to the steering-system motor, a communication line directly communicatively connecting the first ECU and the second ECU, and a gateway module communicatively connecting the first ECU to a controller area network (CAN) bus and communicatively connecting the second ECU to the CAN bus. The first ECU is programmed to, upon detecting a fault, transmit a fault code to the second ECU via the communication line and via the gateway module. The second ECU is programmed to, upon detecting a fault, transmit a fault code to the first ECU via the communication line and via the gateway module.

Abstract: A system for a vehicle includes first and second electronic control units (ECUs) each electrically connected to a steering-system motor, and a computer. The computer is programmed to instruct the first and second ECUs to each provide one-half of a value of a torque signal to the steering-system motor upon determining that both ECUs have a full performance capability.

Abstract: Methods and systems are disclosed for activating a vehicle ignition system. An example vehicle includes an ignition system, a plurality of sensors, and a processor. The processor a processor is configured to determine, based on data received from the sensors, (i) that a person occupies a driver's seat of the vehicle, (ii) that a key fob corresponding to the vehicle is present, and (iii) that an input has been received at a shifter of the vehicle. The processor is also configured to responsively activate the ignition system.

Abstract: A manual steering torque input is measured. A manual steering mode of a vehicle is actuated when the manual steering torque input is below a first torque threshold and above a second torque threshold for longer than a time threshold that is based on a vehicle speed.

Abstract: A system includes a computer that is programmed to determine a vehicle steering wheel angle based on a vehicle steering torque and a vehicle pinion angle and to determine a compensated steering torque by applying a high-pass filter to the determined vehicle steering wheel angle. The computer is programmed to actuate a vehicle component based on the determined compensated steering torque. A parameter of the high-pass filter is based on a vehicle speed.

Abstract: Methods and apparatus for virtual torsion bar steering controls are disclosed. A disclosed example apparatus includes a sensor associated with a steering system to measure an operational angle of the steering system, a virtual torsion bar operatively coupled to the steering system, the virtual torsion bar to calculate a control torque based on a request angle and the operational angle, and a torque compensator to control an output torque of the steering system based on the control torque.
