Abstract
Embodiments of the present disclosure provide a motor control method, a laser radar, and a movable device. The method includes: determining start times of multiple motors, the start times of the multiple motors being partially or completely different; and controlling each motor of the multiple motors to start at a corresponding start time of the motor.
Claims20
A motor control method, applied to a laser radar including multiple motors, comprising:
- determining start times of the multiple motors, the start times of the multiple motors being partially or completely different, and the start time of one motor of the multiple motors being a time when a rotation speed of the one motor starts to increase from 0 RPM to an operating speed of the one motor;
- and
- controlling each motor of the multiple motors to start at a corresponding start time of the motor.
A laser radar comprising:
- multiple motors;
- and
- a processor configured to:
- determine start times of the multiple motors, the start times of the multiple motors being partially or completely different, and the start time of one of the multiple motors being a time when a rotation speed of the one motor starts to increase from 0 RPM to an operating speed of the one motor;
- and
- control each motor of the multiple motors to start at a corresponding start time of the motor.

A motor control method comprising:
- determining start times of multiple motors of a laser radar, the start times of the multiple motors being partially or completely different;
- and
- controlling the multiple motors to start at corresponding start times of the multiple motors, including, for each one motor of the multiple motors:
- obtaining a target rotation speed of the one motor;
- and
- determining a graded rotation speed less than the target rotation speed according to:
- the target rotation speed and an ambient temperature;
- or
- the target rotation speed, the ambient temperature, and a corresponding relationship between rotation speed and current;
- and
- controlling the one motor to start at the graded rotation speed at the start time of the one motor.
