Abstract
A multicore hybrid-electric powertrain controller includes an electric motor control unit and a thermal engine control unit. The electric motor control unit and the thermal engine control unit can be connected by one or more serial connections and an analog/discrete connection. Each of the electric motor control unit and the thermal engine control unit include two processing channels, such as for redundancy and fallback protection.
Claims20
A multicore hybrid-electric powertrain controller comprising:
- an electric motor control unit comprising:
- a first electric motor control channel comprising a first controller of an electric motor and a first electric motor protection processor;
- a second electric motor control channel comprising a second controller of the electric motor and a second electric motor protection processor;
- and
- a switching driver connected to the first electric motor control channel and the second electric motor control channel, wherein the switching driver is configured to provide control inputs determined in at least one of the first electric motor control channel or the second electric motor control channel to the electric motor;
- a thermal engine control unit comprising:
- a first engine control channel comprising a first thermal combustion engine controller and a first thermal engine protection processor;
- a second engine control channel comprising a second thermal combustion engine controller and a second thermal engine protection processor;
- and
- an output drive connected to first engine control channel and the second engine control channel;
- a first serial connection between the electric motor control unit and the thermal engine control unit, wherein the first serial connection is configured to pass control inputs and sensor data between the thermal engine control unit and the electric motor control unit;
- a second serial connection between the electric motor control unit and the thermal engine control unit, wherein the second serial connection is configured to pass the control inputs and the sensor data between the thermal engine control unit and the electric motor control unit;
- and
- an analog/discrete connection between the electric motor control unit and the thermal engine control unit;
- and
- the first and second serial connections between the electric motor control unit and the thermal engine control unit is configured, as an independent communication path and the redundancy of analog/discrete connection;
- and
- the analog/discrete connection is configured, to provide faster protective functions, or responsive to failure of the first serial connection and the second serial connection, to pass the control inputs and the sensor data between the thermal engine control unit and the electric motor control unit.
