An electric vehicle noise sniffer and methods of mitigating packet flow interruptions by noise cancellation and avoidance of noise region envelopes are provided. A vehicle comprises: electrical component(s) that operate according to data indications: and a power line that conveys the data indications and power to the electrical component(s). A method comprises: determining an electrical characteristic of the data indications on the power line: determining a present electrical characteristic of noise on the power line and/or estimating a future electrical characteristic of the noise on the power line: and causing the data indications to change to a new electrical characteristic different from the present electrical characteristic and the future electrical characteristic of the noise on the power line to avoid interference of the noise with the data indications. The electrical characteristics are one or more of in frequency space, amplitude space and direct current offset space.

Electric vehicle noise sniffer and methods of mitigating packet flow interruptions by noise cancellation and avoidance of noise region envelopes

There is provided a method for actuating a component of a vehicle. The method may include applying an initial force to the component to actuate the component, and generating a movement indicator based on whether the component moves in response to the initial force. Moreover, the method may include receiving a freezing indicator associated with a likelihood of the component being immobilized due to freezing. If the movement indicator is negative and the freezing indicator is affirmative, the method also includes applying an adjusted force to the component to mobilize the component.

Methods and apparatuses for actuating a vehicle component

There is provided a method for controlling an electric vehicle. The method includes receiving a regenerative braking activation indicator. If the regenerative braking activation indicator is affirmative, the method includes applying regenerative braking at an initial level to an electric motor of the electric vehicle. The method also includes obtaining a vehicle motion parameter of the electric vehicle measured when the regenerative braking is being applied. In addition, the method includes changing the regenerative braking to a modified level based on the vehicle motion parameter.

Methods and apparatuses for controlling an electric vehicle

There is provided a method of controlling an electric motor having a rotor and a stator. The method includes controlling the motor in a low-speed mode by injecting a high frequency (HF) signal into the motor. The HF signal may have an initial voltage and an initial frequency. The method may also include obtaining a speed of the rotor relative to the stator, and obtaining a reference input being sent to the motor. Moreover, the method may include comparing the speed and the reference input with a speed threshold and a reference input threshold respectively. In addition, the method may include reducing at least one of the initial voltage and the initial frequency if the speed is below the speed threshold and the reference input is below the reference input threshold, to reduce an acoustic noise caused by injecting the HF signal into the electric motor.
