MOTOR CONTROLLER
A system and a motor controller for a motor vehicle, the motor controller having electronics configured to bring about the energization of the windings of an electric motor. A clock generator is configured to send a clock signal which controls the processes of the electronics. The motor controller is operatively connected to a slave of a bus system in order to transmit and/or receive signals, and the clock of a clock signal being provided by the bus master is used via the slave to synchronize the clock generated by the clock generator of the motor controller.
1 . A motor controller for an electric motor of a motor vehicle, comprising:
electronics configured to bring about an energization of windings of the electric motor; and
a clock generator configured to send a clock signal which controls the electronics, wherein:
the motor controller is operatively connected to a slave of a bus system in order to transmit and/or receive signals; and
a clock of the clock signal provided by a bus master is used via the slave to synchronize the clock generated by the clock generator of the motor controller.
2 . The motor controller of claim 1 , wherein the bus system comprises an LIN bus.
3 . The motor controller of claim 1 , wherein the electric motor comprises a brushless direct current motor.
