摘要： 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.

摘要： 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.
