Methods for providing steering assistance for an electromechanical steering system having a redundant control unit with a primary and a secondary control path. Respective primary and secondary control paths each have a computing unit, gate driver module, and power module. The method includes detecting an applied steering torque; calculating a primary and secondary motor target torque in the primary computing unit as a function of the applied steering torque; transmitting the primary motor target torque to a primary motor controller of the primary computing unit; determining primary motor currents to operate a primary electric motor or a primary winding group of the electric motor in the primary motor controller; transferring the secondary motor target torque from the primary computing unit to a secondary motor controller and determining secondary motor currents for operation of a secondary electric motor or a secondary winding group of the electric motor.

Method for providing steering assistance for an electromechanical steering system of a motor vehicle comprising a redundantly designed control device

A motor electric control unit (ECU) for an electromechanical power steering mechanism, which controls current through an electric assist motor in response to steering mechanism sensors' signals. The ECU may comprise at least two channels. Each channel has the steering mechanism sensors in a redundancy concept. At least one voter that is assigned to an actuator and is configured to vote on the correct steering mechanism sensors' outputs of the at least two channels. The steering mechanism sensors may include a steering column torque sensor and an RPS sensor for sensing a rotor angle of the electric assist motor. Each of the at least two channels may include processors that have different software to protect against systematic faults.

Multichannel electronic control unit architecture for electromechanical power steering systems

A controller may have a plurality of self-diagnostic functions, each of which is configured for checking a function of an assigned hardware component of the controller. Each of the self-diagnostic functions may have at least one safety limit value, which is configured such that when the at least one safety limit value is exceeded the corresponding hardware component is switched off. Each of the self-diagnostic functions may have at least one quality limit value, the absolute value of which is smaller than an absolute value of the at least one safety limit value. The at least one quality limit value can be configured such that a quality-relevant state can be detected in the assigned hardware component when the at least one quality limit value is exceeded.

Controller with an early warning function designed to detect a signal reduction present in a hardware component

A motor electric control unit (ECU) for an electromechanical power steering mechanism, which controls current through an electric assist motor in response to sensed vehicle signals, wherein the ECU comprises an application specific integrated circuit (ASIC) design, that implements safety and platform features in hardware.

Hardware implemented motor control and platform for EPS

A method can be employed to provide a remote online software update to a motor vehicle. The motor vehicle may have an ECU with an MCU having an internal memory, and with an external memory that is located outside the MCU and is configured to communicate with the MCU via a communication link. The method may involve starting to download a new software version, storing the new software version in the external memory, and once the new software version is fully downloaded deleting the software version running on the MCU and programming the new software version from the external memory.
