Abstract

The invention provides a brushless motor controller for a dual-input signal vehicle. The brushless motor controller comprises a single chip microcomputer, a pulse width signal control unit and a voltage signal control unit. The pulse width signal control unit comprises a capacitor C27, a diode D4, a resistor R53, a triode Q9, a triode Q10, a resistor R50, a resistor R51, a resistor R49, and a resistor R54. The voltage signal control unit comprises a resistor R17, a resistor R48, a diode D5, a diode D6, and a capacitor C28. The controller can be compatible with voltage and pulse signal input. Through the collection of two paths of signals which are a voltage input signal and a pulse width input signal, the two paths signals are connected to the same input end, and the brushless motor can be controlled to work no matter an external input is a voltage signal or a pulse width signal.

Description

technical field [0001] The invention relates to a dual-input signal vehicle brushless motor controller, and relates to the field of production and manufacturing of brushless motor controllers in the automotive micromotor industry. Background technique [0002] The brushless motor controller has a variety of input control signals, most of which are divided into these types: voltage input control signal, pulse width input control signal, LIN input control signal, CAN input control signal, etc. According to market promotion and application, some car manufacturers are still using voltage input signals to control brushless motors. The disadvantage of voltage input signals is that the voltage signals have energy loss during transmission and cannot achieve precise control. In the signal transmission process, the pulse width input signal has no energy loss and can meet the precise control requirements, so it is more adaptable to the development of the market. Due to the inconsisten...
